Commission earned by William is $ 45.84
Solution:Given that,
William makes a commission of 6% percent on everything he sells
He sells a computer for $764.00
To find: Commission amount of William
Given that he makes a commission of 6 % on everything he sells. So he has received a commission of 6 % of $ 764.00
Commission amount of William = 6 % of $ 764.00
a % of b can be written in fraction as [tex]\frac{a}{100} \times b[/tex]
[tex]6 \% \text { of } 764=\frac{6}{100} \times 764=0.06 \times 764=45.84[/tex]
Thus commission earned by William is $ 45.84

Hodi is building a birdhouse. Each of the
four walls of the birdhouse needs to be
5.5 inches long. Hodi has a piece of
board that is 24.5 inches long. Is the
board long enough to be cut into the four
walls of the birdhouse? Estimate using
compatible numbers.
Answer:
This board of 24.5 inches long is not enough to be cut into the four walls of the bird house.
Step-by-step explanation:
Hodi is building a birdhouse. Each of the four walls of the birdhouse needs to be 5.5 inches long.
So, to get four 5.5 inches long walls we need to have (5.5 × 4) = 22 inches ling board from which four equal 5.5 inches board can be made.
Now, Hodi has a piece of a board that is 24.5 inches long.
Therefore, this board is not enough to be cut into the four walls of the birdhouse. (Answer)
the square root of 52 is between which two consecutive intergers?
a) 26 and 27
b) 7 and 8
c) 25 and 26
d) 8 and 9
Answer: 7 and 8
Step-by-step explanation:
The square root of 7 is 49 and the square root of 8 is 64
52 is in between the 2 consecutive integers 7 and 8
Answer: b) 7 and 8
Step-by-step explanation:
The formula for calculating the square root of non perfect square is given as :
square root of non perfect square = square root of the nearest lower perfect square + (difference between the number and the perfect square)/ 2x the perfect square.
To find the square root of 52.
The nearest lower perfect square to 52 is 49 , applying the formula , we have:
[tex]\sqrt{52}[/tex] = [tex]\sqrt{49}[/tex] - [tex]\frac{52-49}{2\sqrt{49}}[/tex]
[tex]\sqrt{52}[/tex] = 7 + [tex]\frac{3}{2(7)}[/tex]
[tex]\sqrt{52}[/tex] = 7 + [tex]\frac{3}{14}[/tex]
This shows clearly that [tex]\sqrt{52}[/tex] is between the integer 7 and 8
The equation 5x - 7(x-1) = ax+b has exactly one solution.
Answer:
a = -2 and b = 7
Step-by-step explanation:
We need to solve for the value of "a" and "b".
We need to distribute and make the left side of the equation same form as the right side of the equation and match the coefficients, simple.
We will use the distributive property shown below to expand the left side and simplify.
Distributive Property: a(b-c) = ab - ac
Now, simplifying left hand side:
5x - 7(x - 1)
= 5x -7(x) -7(-1)
= 5x -7x +7
= -2x + 7
The right hand side is "ax + b".
If we match left-hand side and right-hand side, we see that:
a = -2
and
b = 7
THese are the only solution.

Describe the functional relationship between the two quantities in the graph.
Answer:
[tex]B=\frac{4}{3}A[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have a proportional relationship because the line passes through the origin (0,0)
Find the value of k
[tex]k=\frac{B}{A}[/tex]
take the point (3,4)
A=3,B=4
substitute
[tex]k=\frac{4}{3}[/tex]
The equation of the line is
[tex]B=\frac{4}{3}A[/tex]

Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. How many total kilograms of candy did he buy?
Answer:
1.26 kg.
Step-by-step explanation:
We have been given that Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. We are asked to find the amount of candy bought by Mr. Snow in kilograms.
First of all, we will find the amount of candy in grams by multiplying 90 grams by 14 as:
[tex]\text{Amount of candy bought in grams}=14\times 90[/tex]
[tex]\text{Amount of candy bought in grams}=1260[/tex]
We know that 1 kilogram is equal to 1000 grams. To convert 1260 grams into kg, we will divide 1260 by 1000 as:
[tex]\text{Amount of candy bought in kilograms}=\frac{1260}{1000}[/tex]
[tex]\text{Amount of candy bought in kilograms}=1.26[/tex]
Therefore, Mr. Snow bought 1.26 kilograms of candy.

Point p is chosen at random on KN. Find the probability that p is on LM.
Answer:
[tex]\frac{4}{11}[/tex]
Step-by-step explanation:
The total length of KN is 11 units and the length of LM is 4 units. This means that the probability would be [tex]\frac{4}{11}[/tex]
Answer : The probability that p on LM is, [tex]\frac{4}{11}[/tex]
Step-by-step explanation :
Probability : It is defined as the extent to which an event is likely to occur. That means, it is measured by the ratio of the favorable outcomes to the total number of possible outcomes.
[tex]\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of favorable outcomes}}[/tex]
Favorable outcomes on line KN are, 2, 4, 5
Favorable outcomes on line LM is, 4
Number of favorable outcomes = 4
Total number of outcomes = 2 + 4 + 5 = 11
[tex]\text{Probability}=\frac{\text{Number of favorable outcomes for a multiple of 3}}{\text{Total number of favorable outcomes}}[/tex]
[tex]\text{Probability}=\frac{4}{11}[/tex]
Therefore, the probability that p on LM is, [tex]\frac{4}{11}[/tex]

How much less would a 23-year-old female pay for a $25,000 policy of 20 year life insurance (@ $2.90 per $1000) than straight life (@ $15.78 per $1000)?
Answer:
The female would pay $322.00 less for a policy of $25,000
Step-by-step explanation:
Since we have given that
Amount for policy = $25000
If she opt for 20 year life insurance at $2.90 per $1000.
so, her amount of premium becomes
[tex]25000\times \frac{2.9}{1000}[/tex]
=$72.50
If she opt for straight life insurance at $15.78 per $1000,
Then, her amount of premium becomes
[tex]25000 \times \frac{15.78}{1000}[/tex]
= $394.50
Difference between them is given by
$394.50-$72.5 = $322.00
Answer:
The answer to this question is $322.
Step-by-step explanation:
From the question, we recall the following
23-year-old female pay for a $25,000 policy less policy of 20 year life insurance.
The first step is to calculate the policy of 20 year life insurance
The number of thousands on 2500 is, 25000/1000=25
25*2.9 = 72.5
The next step is to get the straight life
Thus,
25×15.78 = 394.5
Now,
How much less would the 23 year old pay
394.5−72.5 = $322

A group of mountain climbers begin a expedition with 250 pounds of food. They plan to eat a total of 12 pounds of food per day . Write and solve a linear equation to find the number of days their food will last
Answer:
The equation representing total food consumption in [tex]x[/tex] days can be given as:
[tex]y=12x[/tex]
where [tex]y[/tex] represents total food taken which is =250 pounds and [tex]x[/tex] represnts the number of days the food will last.
The food will last for [tex]20\frac{5}{6}[/tex] days.
Step-by-step explanation:
Total pounds of food taken at the beginning = 250 pounds
Food consumed per day = 12 pounds
Let the total food at the beginning be = [tex]y[/tex] pounds
Let number of days the food will last be = [tex]x[/tex] days
Using unitary method to find the food consumed in [tex]x[/tex] days.
If in 1 day food consumed = 12 pounds
Then, in [tex]x[/tex] days food consumption = [tex]12\times x = 12x[/tex] pounds
So,the equation representing total food consumption in [tex]x[/tex] days can be given as:
[tex]y=12x[/tex]
Total food taken =250 pounds
Plugging in [tex]y=250[/tex] in the equation:
[tex]250=12x[/tex]
Solving for [tex]x[/tex]
Dividing both sides by 12.
[tex]\frac{250}{12}=\frac{12x}{12}[/tex]
[tex]\frac{250}{12}=x[/tex]
Simplifying fractions.
[tex]\frac{125}{6}=x[/tex]
Converting fraction to mixed number by writing quotient as whole number, remainder as numerator and divisor as denominator.
∴ [tex]x=20\frac{5}{6}[/tex] days.
Thus, the food will last for [tex]20\frac{5}{6}[/tex] days.

What is the probability of spinning these two spinners and having each one land
on a 3? Write the probability as a decimal.
Answer:
The probabilities are 0.4 and 0.6 respectively.
Step-by-step explanation:
We are given two spinning wheels with numbers on it and we have to find the probability of getting 3.
In the first wheel, there are 5 slots and the numbers are 3, 3, 2, 5 and 4.
So the probability of getting 3 =[tex]\frac{number of 3's}{total number of slots}[/tex]
= [tex]\frac{2}{5}[/tex]
= 0.4
In the second spinner there are three 3's and total of 5 slots.
So probability of getting 3 = [tex]\frac{number of 3's}{total number of slots}[/tex]
= [tex]\frac{3}{5}[/tex]
= 0.6
Hence the probabilities are 0.4 and 0.6 respectively.
Compare the line passing through the points (-2,-9) and (4, 6) with the line given by the equation
y = 2/5x -4.
A) they have the same slope
B) they have the same x-intercept
C) the two lines are perpendicular
D) they have the same Y-intercept
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
[tex]y = mx + b[/tex]
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points:
[tex](x_ {1}, y_ {1}) :( 4,6)\\(x_ {2}, y_ {2}): (- 2, -9)[/tex]
We can find the slope:
[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-9-6} {- 2-4} = \frac {-15} {- 6} = \frac {5} {2}[/tex]
Thus, the equation is of the form:
[tex]y = \frac {5} {2} x + b[/tex]
We substitute one of the points and find "b":
[tex]6 = \frac {5} {2} (4) + b\\6 = 10 + b\\6-10 = b\\b = -4[/tex]
Finally, the equation is:
[tex]y = \frac {5} {2} x-4[/tex]
Thus, it is observed that the lines have the same y-intercept
Answer:
Option D
the sum of 6c- 5c and the opposite of 6c
Answer:
[tex]-5c[/tex]
Step-by-step explanation:
To find: The sum of [tex]6c-5c[/tex] and opposite of [tex]6c[/tex]
Opposite of [tex]6c[/tex] means taking the opposite sign.
[tex]6c[/tex] is positive. So, opposite sign is [tex]-6c[/tex].
Therefore, the addition is given as:
[tex]=6c-5c+(-6c)[/tex]
Opening the parenthesis, we get:
[tex]6c-5c-6c[/tex]
Now, as per PEDMAS rule, we subtract [tex]6c\ and\ 5c[/tex], we get
[tex]6c-5c=(6-5)c=1c[/tex]
Now, we are left with [tex]1c-6c[/tex]
Subtracting a bigger number from a smaller number will give a negative answer.
So, [tex]1c-6c=(1-6)c=-5c[/tex]
Therefore, the final answer is [tex]-5c[/tex]

Fill in the blank with a number to make the expression a perfect square.
w² - 6w + ___
Answer:
9 should be added to the expression to make it a perfect square
Step-by-step explanation:
Given expression:
[tex]w^2-6w+_-[/tex]
To fill in the missing term such that the expression becomes a perfect square.
Solution:
In order to make the expression a perfect square we will use completing the square method.
We have : [tex]w^2-6w[/tex]
By complete the square method we will add the square of the quotient of the co-efficient of the middle term which is [tex]-6w[/tex] and 2.
The co-efficient of middle term = -6
Thus the number to be added will be = [tex](\frac{-6}{2})^2=(-3)^2=9[/tex]
Thus, on adding 9 the expression will become:
[tex]w^2-6w+9[/tex] which is a perfect square of the binomial [tex](w-3)[/tex]
This can be shown as:
[tex](w-3)^2=w^2-6w+9[/tex]
Thus, we add 9 to the expression to make it a perfect square.
Answer:
9
Step-by-step explanation:
Given: [tex]w^{2} -6w+[/tex]
Finding the number to make expression a perfect square.
From the expression we can see that coefficient of variable is 1 and -6.
Now, lets take a= 1 and b= -6 and finding c .
∴ c= [tex]\frac{b^{2} }{4a}[/tex]
Subtituting the value of a and b.
⇒ c= [tex]\frac{-6^{2} }{4\times 1} = \frac{36}{4}[/tex] (∵ [tex]-6\times -6= 36[/tex])
∴ c= 9
Next putting the value in the expression.
[tex]w^{2} -6w+9[/tex]
= [tex](w-3)(w-3)[/tex]
= [tex](w-3)^{2}[/tex]
Hence, 9 is a number to make the expression a perfect square.
