Answer:
There are 4 chairs in one row.
Step-by-step explanation:
Let [tex]$ x $[/tex] be the number of chairs in one row.
That is the length of one row.
Now, from the given data, three rows of length 3x can be formed with one chair left.
Or, if 15 extra chairs given, we can form 7 rows of the same length.
This means that there are [tex]$ 3x + 1 $[/tex] chairs in the first case. And since with 15 extra chairs we can form 7 rows, the equation would be
[tex]$ (3x + 1) + 15 = 7x $[/tex]
Solving this for '[tex]$ x $[/tex]', we get:
[tex]$ 3x + 16 = 7x $[/tex]
[tex]$ \implies 4x = 16 $[/tex]
[tex]$ \implies x = 4 $[/tex]
Therefore, the length of each row is four.
That is, there are four chairs in one row.

Question # 1 (Top Left)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 29°Right angle = 90°The missing side x can be calculated by the formula:
sinФ = opposite ÷ hypotenuse
sin(29°) = x ÷ 3
0.4848 = x ÷ 3
x ÷ 3 = 0.4848
x = 0.4848 × 3
x = 1.45 cm
Hence, x = 1.45 cm is the length of missing side.
Question # 2 (Top Center)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 21°Right angle = 90°The missing side x can be calculated by the formula:
tanФ = opposite ÷ adjacent
tan(21°) = x ÷ 4
0.3838 = x ÷ 4
x ÷ 4 = 0.3838
x = 0.3838 × 3
x = 1.15 cm
Hence, x = 1.15 cm is the length of missing side.
Question # 3 (Top Right)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 66°Right angle = 90°The missing side x can be calculated by the formula:
cosФ = adjacent ÷ hypotenuse
cos(66°) = x ÷ 8
0.4067 = x ÷ 8
x ÷ 8 = 0.4067
x = 0.4067 × 8
x = 3.25 cm
Hence, x = 3.25 cm is the length of missing side.
Question # 4 (Bottom Right)

16A
Equivalent fractions are fractions multiplied by a same constant, on the numerator and denominator:
[tex]\frac{4*2}{5*2}=\frac{8}{25}=\frac{4*3}{5*3}=\frac{12}{15}[/tex]
[tex]\frac{5*2}{6*2}=\frac{10}{12}=\frac{5*3}{6*3}=\frac{15}{18}[/tex]
15a is False as a common denominator isn't clear; 15b is False because the time in the morning is undefined; 15c is True assuming the morning was 3 hours. 16 needs further clarification.
15a ⇒False. To find the common denominator, we need to look at the fractions given. If there are fractions involved, more context is needed to validate this statement. Please provide relevant fractions.15b ⇒False. There is no concrete information given about the exact time spent in the morning to confirm this statement. If he spent 5 hours in the afternoon and the total time spent isn't specified, we cannot conclude the morning time is 3 hours.15c ⇒True. Since he painted for 5 hours in the afternoon, and we assume the morning time to be 3 hours (as per previous interpretations), Mr. Clements painted 2 hours longer in the afternoon (5 - 3 = 2).So, correct answer is 15a. False 15b. False 15c.True

Answer: Area of Δ DUO = 12.0 square units.
Step-by-step explanation:
From the diagram, Δ DPA is a right angled triangle and right angled at P.
Therefore ∠D will be
Tan ∅° = PA/DP ie, opposite side all over the adjacent.
= 4.5/3.75
Tan∅° = 1.2
to calculate ∅°, we know find the inverse of Tan 1.2
∅ = Tan^-1 1 .2 from your log tables or calculator
∅° = 50.20°.
= 50°
Since line DR is ⊥ to line OP
∠ADR = 90° - 50°
= 40°.
From the diagram,
∠ADR = ∠UDR = 40°
Therefore,
∠ODU = 180 - ( 40 + 40 + 90 ) { Angle on a straight line }
= 180 - 170
= 10°
From Δ UDM , line MU is he height of the required Δ DUO whose area is to be determined.
Now find the height MU
Tan10.0° = MU/10, where MU is the opposite side and 10.0 is the adjacent from the diagram given.
MU = Tan10.0 x 10.0
= 0.1763 x 10.0
= 1.763
Therefore to calculate the area of Δ DUO
= 1/2 x base x height
= 1/2 x line OD x line MU
= 1/2 x 14.0 x 1.763
= 7 x 1.763
= 12.341
= 12.0 square units.

Angle X and angle Y are supplementary angles. Angle Y measures 33 degrees. what is the measure of angle X?
Answer: 147
Step-by-step explanation:
Supplementary: Angles that equal 180
180-33=147
147+33=180
The measure of supplement angle X is 147°.
Given that, angle X and angle Y are supplementary angles.
What are supplementary angles?Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Here,
∠X+∠Y=180°
⇒ ∠X+33°=180°
⇒ ∠X=180°-33°
⇒ ∠X=147°
Hence, the measure of supplement angle X is 147°.

Which of the following statements is true about the values of the coordinate points in a figure when the figure is reflected over the y-axis
Answer:
they will have the same y-coordinate from the point it was reflected because it is reflected over the y-axis.
but you didn't provide the following statements, so i do not know.
The values of the coordinates will be same for y ordinate but will be negated for x abscissa , which means (x,y) will become (-x, y)
How does the reflection works?When the graph is reflected over y axis, then all the x coordinates of all points become negation of themselves. It is because those x coordinates who were on the positive sides now are on the negative sides and those who were on the negative side are now on the positive side.
Thus:
(x,y) turns to (-x,y)
Thus, the values of the coordinates will be same for y ordinate but will be negated for x abscissa , which means (x,y) will become (-x, y)

The tens digit of a two-digit number is 3 less than the units digit. Find the original number, if the sum of that number and the number reversed is 143.
Let...
x=ones digit
x-3=tens digit
The number in terms of x would be...
10(x-3)+x = 11x-30
The number with its digits reversed would be...
10(x)+x-3 = 11x-3
And...
11x-30+11x-3=143 We can solve for x!
22x=176
x=8
The number would be 58.
answer: 58
The two digit number needed is valued 58.
Given that:
The tens of a two digit number = unit's digit - 3
Number reversed + The number itself = 143
Let the ones digit of that two digit number be x and the tens digit be y. Then by place value concept, we have:
[tex]10(y) + x[/tex]
Since the tens digit = unit digit - 3
Thus we have:
[tex]y = x - 3[/tex]
or the number is :
[tex]10(x-3) + x = 11x - 30[/tex]
Now sum of the number and the number reversed is 143, which means:
[tex]143 = 10(x) + (y) + 10(y) + x = 10x + (x-3) + 11x - 30\\143 = 22x - 3 - 30\\x = 8[/tex]
Thus, the number is [tex]10(x-3) + x = 50 + 8 = 58[/tex]

This Christmas, your brother Jack will be 2 years from being twice as old as your sister Jen. The sum of Jacks age and three times Jen's age is 66. How old is Jen?
Age of Jen is 13.6 years old
Solution:
Let "x" be the age of Jack and "y" be the age of Jen
Given that This Christmas, your brother Jack will be 2 years from being twice as old as your sister Jen
The above sentence can be written mathematically as:
Jack age + 2 = twice of age of Jen
[tex]x + 2 = 2y\\\\x = 2y - 2---- eqn 1[/tex]
The sum of Jacks age and three times Jen's age is 66
Jack age + three times Jen age = 66
x + 3y = 66 ---- eqn 2
Substitute eqn 1 in eqn 2
2y - 2 + 3y = 66
5y - 2 = 66
5y = 68
y = 13.6Thus age of Jen is 13.6 years old

A wholesaler buys pairs of sunglasses
for $5.50 each. He then marks up the
wholesale cost 80% to create a retail
price for his customers. Customers must
then pay an additional 7% tax on the
retail price. What is the total cost of a
pair of sunglasses to the wholesaler's
customers, including tax, rounded to
the nearest penny?
A customer will pay $10.59, including sales tax, for a pair of sunglasses.
Step-by-step explanation:
Given,
Purchase price of sunglasses = $5.50
Mark up = 80%
Amount of mark up = 80% of purchase price
Amount of mark up = [tex]\frac{80}{100}*5.50=0.80*5.50[/tex]
Amount of mark up = $4.40
Retail price = Purchase price+mark up
Retail price = 5.50+4.40 = $9.90
Sales tax = 7% of retail price
Sales tax = [tex]\frac{7}{100}*9.90=0.07*9.90[/tex]
Sales tax = $0.69
Total paid by customer = retail price + sales tax
Total paid by customer = 9.90 + 0.69 = $10.59
A customer will pay $10.59, including sales tax, for a pair of sunglasses.

____ in.
Answer:
(1) 9.106 cm
(2) 49.612 inches
Step-by-step explanation:
Answer:
1. C =9.106 cm 2.C =49.612 inches
Step-by-step explanation:
To solve these problems, we will follow the steps below;
First write down the formula for calculating the circumference of the circle
C= 2πr
where c is the circumference of the circle and r is the radius of the circle
1) From the question diameter = 2.9 cm, but radius is half of the diameter, this implies that radius = [tex]\frac{d}{2}[/tex]= [tex]\frac{2.9}{2}[/tex]=1.45 cm
We can now proceed to insert the values into the formula;
C= 2πr
= 2×3.14×1.45
=9.106 cm
C =9.106 cm
2) From the question, radius = 7.9 inches and π=3.14
We can now go ahead to insert the values into the formula C= 2πr
C = 2×3.14× 7.9
=49.612 inches
C =49.612 inches

Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept (0, b)
We have two points (4, 2) and (0, -1) → b = -1.
Calculate the slope:
[tex]m=\dfrac{-1-2}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}[/tex]
Finally:
[tex]y=\dfrac{3}{4}x-1[/tex]
The equation of the line that passes through the points (4, 2) and (0, -1) is y = 0.75x + 1.
Explanation:The subject of this question is Mathematics, and it involves finding the equation of a line given two points. To find the equation of the line that contains the points (4, 2) and (0, -1), we first find the slope (m) using the formula m = (y2 - y1) / (x2 - x1).
Substituting the given points into the formula, we get m = (-1 - 2) / (0 - 4) = -3 / -4 = 0.75.
We then use the point-slope form of a linear equation, y - y1 = m(x - x1), and substituting m = 0.75, x1 = 4, and y1 = 2, we get the equation of our line as: y - 2 = 0.75(x - 4), which simplifies to y = 0.75x + 1.

There are between 50 & 60 eggs in a basket. When roza counts by 3's there are 2 leftover and when she counts by 5's there are 4 leftover. How many eggs are in the basket?
(is there a way to solve this without having to go through all the options)
There are 59 eggs in the basket
Step-by-step explanation:
There are between 50 & 60 eggs in a basket
When Roza counts by 3's there are 2 leftoverWhen she counts by 5's there are 4 leftoverWe need to find how many eggs in the basket
∵ When Roza counts by 3's there are 2 leftover
∵ When she counts by 5's there are 4 leftover
- That means the number of eggs when divided by 3 give
remainder 2 and when divided by 5 give remainder 4
- To find the number look for the numbers that divisible by 5 and
add 4 to them and then check the remainder when they divided
by 3
∵ Between 50 and 60 there is only one number divisible by 5
is 55 (not including 50 or 60)
∵ 55 + 4 = 59
∴ 59 gives remainder 4 when divided by 5
Let us check them with 3
∵ 59 - 2 = 57
∵ 57 is divisible by 3 ⇒ (57 ÷ 3 = 19)
∴ 59 when divide by 3 gives remainder 2
∴ 59 gives remainder 4 when divided by 5 and remainder 2 when
divided by 3
∴ The number of eggs in the basket is 59
There are 59 eggs in the basket

cc fewer cookies than she would have received had all of the cookies been evenly divided among the
8 grandchildren.
Answer:
[tex]12-c[/tex] Cookies
Step-by-step explanation:
The question is to find how many cookies did Cindy receive (write as an expression)?
Total cookies baked = 96
If evenly divided among 8 grandchildren, each would get:
[tex]\frac{96}{8}=12[/tex]
Each grandchildren would have gotten 12 cookies
Now, Cindy received "c" fewer than this (12), so Cindy received:
12 - c Cookies
Cindy Received = 12 - c Cookies
Answer:
96/8 - c.
Step-by-step explanation:
She is divideing among the grandkids so it would be 98/8-c
in the right triangle shown, angle A=30 and AC=18 how long is AB?
Answer:
[tex]AB=9\sqrt{3}\ units[/tex]
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABC
The cosine of angle of 30 degrees is equal to divide the adjacent side to angle of 30 degrees by the hypotenuse
so
[tex]cos(30^o)=\frac{AB}{AC}[/tex]
we have
[tex]cos(30^o)=\frac{\sqrt{3}}{2}[/tex]
[tex]AC=18\ units[/tex]
substitute
[tex]\frac{\sqrt{3}}{2}=\frac{AB}{18}[/tex]
solve for AB
[tex]AB=(18)\frac{\sqrt{3}}{2}[/tex]
[tex]AB=9\sqrt{3}\ units[/tex]

Anita and Susanna are in a 5-mile bike race. The graph shows each racers distance from the start as a function of time. What could describe Anita's race from minute 3 to minute 5
Answer:
The best could describe Anita's race from minute 3 to minute 5, She was standing, not moving, she could have been in an accident.
Step-by-step explanation:
See the attached figure.
As shown in the figure, we can note that the distance from minute 3 to minute 5 is constant which is equal to the distance at minute 3.
So, the average distance from minute 3 to minute 5 will be zero and hence the speed of Anita will be zero
So, From minute 3 to minute 5, She was standing, not moving.
Note: speed of Anita from minute 3 to minute 5
= ( distance difference) / (time difference) = zero / (5-3) = 0/2 = 0
To describe the race from minute 3 to 5, analyze the graph paying attention to the x and y axis and the slope of the curve. A straight line suggests constant speed, an upward line implies acceleration, and a downward line denotes deceleration.
Explanation:To describe Anita's race from minute 3 to minute 5, we need to analyze the provided graph which depicts the distance from the start as a function of time for both racers. In this case, we do not have the actual graph so it's important that when you are presented with a graph you pay attention to the
x and y axis
, which in this instance are time and distance. It's vital to also look at the slope of the curve during those minutes 3 to 5 for Anita. If it's a straight line, it means Anita was biking at a
constant speed
. If the line is going upward, Anita was accelerating, and if the line is going downward, she was decelerating. Without the graph itself, it's hard to provide a definitive answer. But the basic method of reading the graph will help you understand the function of time and distance in the context of a race.
