Answer:
A: [tex]7x+y=801[/tex]
B: [tex]18x+3y=1949[/tex]
Step-by-step explanation:
we are given system of equations as
[tex]84x+12y=9612[/tex]
[tex]126x+21y=13643[/tex]
We can simplify each system of equations
[tex]84x+12y=9612[/tex]
we can factor out common terms
[tex]12\times 7x+12\times y=12\times 801[/tex]
[tex]12(7x+y)=12\times 801[/tex]
we can divide both sides by 12
[tex]7x+y=801[/tex]
now, we can simplify second system of equation
[tex]126x+21y=13643[/tex]
Firstly, we can factor
[tex]7\times 18x+7\times 3y=7\times1949[/tex]
[tex]7(18x+3y)=7\times1949[/tex]
we can divide both sides by 7

The area of the rectangular slab of foam insulation is 30 square meters. Find the dimensions of the slab.
m (smaller value)
m (larger value)
The dimensions of the slab are:
Length = 3 meters
Width = 10 meters
To find the dimensions of the rectangular slab, we'll use the given area and the expressions for length and width.
Given:
Area = 30 square meters
Length = w
Width = 2w + 4
We can use the formula for the area of a rectangle to solve for w:
Area = Length × Width
Substituting the given values:
30 = w × (2w + 4)
Expanding the equation:
30 = 2w² + 4w
Rearranging the equation in standard quadratic form:
2w² + 4w - 30 = 0
Now, we can solve this quadratic equation using factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:
w = (-b ± √(b² - 4ac)) / (2a)
In this case, a = 2, b = 4, and c = -30. Substituting these values into the formula:
w = (-4 ± √(4² - 4(2)(-30))) / (2(2))
w = (-4 ± √(16 + 240)) / 4
w = (-4 ± √256) / 4
w = (-4 ± 16) / 4
We have two possible solutions for w:
w = (-4 + 16) / 4 = 12 / 4 = 3
w = (-4 - 16) / 4 = -20 / 4 = -5
Since the width of the slab cannot be negative, we discard the second solution (w = -5).
Therefore, the width of the slab (w) is 3 meters.
Now, we can find the length using the given expression:
Length = w = 3 meters
Therefore, the dimensions of the slab are:
Length = 3 meters
Width = 2w + 4 = 2(3) + 4 = 6 + 4 = 10 meters

a quadrilateral has interior angles 85, 105 and 120 what is the measure of the 4th angle?
__________________
Answer: [tex]50^{\circ}[/tex]
Step-by-step explanation:
By the definition of quadrilateral,
A quadrilateral has four interior angles and the sum of all interior angle of a quadrilateral is always equal to [tex]360^{\circ}[/tex]
Here the measurements of three interior angles are [tex]85^{\circ}[/tex], [tex]105^{\circ}[/tex] and [tex]120^{\circ}[/tex]
Let the measurement of fourth angle is x degree.
Thus, [tex]85^{\circ}+105^{\circ}+120^{\circ}+x=360^{\circ}[/tex]
[tex]310^{\circ}+x=360^{\circ}[/tex]
[tex]x = 360^{\circ}-310^{\circ}=50^{\circ}[/tex]
Thus, the measure of fourth angle is [tex]50^{\circ}[/tex]
The measure of the 4th angle is 50 degrees.
Explanation:To find the measure of the fourth angle of a quadrilateral, we need to know that the sum of all the interior angles of a quadrilateral is always 360 degrees. Therefore, to find the measure of the fourth angle, we can subtract the sum of the other three angles from 360. In this case, the given angles are 85, 105, and 120 degrees, so the sum of these three angles is 85 + 105 + 120 = 310 degrees. To find the measure of the fourth angle, we subtract 310 from 360: 360 - 310 = 50 degrees.

Answer:
A
Step-by-step explanation:
this is a standard right triangle 30-60-90
with legs 1 and [tex]\sqrt{3}[/tex] and hypotenuse 2, hence
s = [tex]\sqrt{3}[/tex] and h = 2
Answer:
A. [tex]\sqrt{3}[/tex] ; 2
Step-by-step explanation:
Since We have all the angles of the triangle and one side we can use SIN, COS, and TAN to find the missing side lengths. SIN which is [tex]sin(x) = \frac{opposite}{hypotenuse}[/tex] can be used to find the hypotenuse
[tex]sin(30) = \frac{1}{h}[/tex]
[tex]\frac{1}{sin(30)} = \frac{h}{1}[/tex] ..... inverse both sides
[tex]\frac{1}{sin(30)} = h[/tex]
[tex]2 = h[/tex]
Now we can use the Pythagorean theorem to find the missing length. The Pythagorean Theorem is [tex]a^{2} +s^{2} = h^{2}[/tex]. So we just plug in the values we already have and solve for s.
[tex]1^{2} +x^{2} = 2^{2}[/tex]
[tex]1+s^{2} = 4[/tex]
[tex]s^{2} = 3[/tex]
[tex]s = \sqrt{3}[/tex]
In Conclusion, s = [tex]\sqrt{3}[/tex] and h = 2

3.a volunteer has 12 pounds of birdseed to put in bird feeders in all of the city parks. there are 3 ¼ Cups of birdseed in pounds, and each bird feeder holds about ¾ cups of birdseed.how many birds feeders can the volunteer fills completely?
Answer:
4 Bird Feeders
Step-by-step explanation:
3 1/4 ALSO is 13/4
13/4 dived by 3/4 or 13/3 witch is 4 and some extra so it can only fill four feeders fully
Answer:
52 bird feeders
Step-by-step explanation:
First, you must determine how much birdseed the volunteer has in cups. To do this, multiply the 12 pounds by the 3 1/4 cups, as there are 3 1/4 cups in one pound. This means the volunteer has 39 cups of birdseed.
Then you must divide the amount of birdseed the volunteer has (39 cups) by the amount of birdseed needed to fill a bird feeder (3/4 cups), which will give you the amount of bird feeders the volunteer can fill (52 bird feeders).
Linda has $9.00 in her wallet. she buys a card for $1.17. she wants to buy some pens that cost $2.65. what is the maximum number of pens can she buy
Answer:
2 pens
Step-by-step explanation:
Let x represent the number of pens Linda buys. Since they cost $2.65 each, this gives us the expression 2.65x.
Adding the cost of the card to this gives us the expression 2.65x+1.17.
She has a total of $9.00; this gives us the equation
2.65x+1.17 = 9.00
Subtract 1.17 from each side:
2.65x+1.17-1.17 = 9.00-1.17
2.65x = 7.83
Divide both sides by 2.65:
2.65x/2.65 = 7.83/2.65
x = 2.95
We cannot buy a portion of a pen, so the most she can buy is 2 pens.
Answer:
The answer is 2 pens.
Step-by-step explanation:
Total amount Linda has in her wallet = $9
Amount spent on buying a card = $1.17
So, amount left with Linda = [tex]9-1.17=7.83[/tex]
Now, she wants to buy pens that cost $2.65, so the maximum number of pens she can buy are = [tex]\frac{7.83}{2.65}= 2.9[/tex]
But, pens cannot be in decimal, so the maximum pens she can buy are 2.

create a real life example using either temperature or money to compare -3 and -5
Example with temperature:
The temperature -3 degrees is warmer than -5 degrees. This applies to celsius or fahrenheit. You might also write "negative 3 degrees" as "3 degrees below zero"; the same applies for -5. The absolute difference between the two temperatures is 2 degrees.
=================================================
Example with money:
If your bank balance is -3 dollars and your friend's bank balance is -5 dollars, then your friend owes more money to the bank (s/he owes $2 more than you do).
Negative balances mean you are in debt. Another way to look at this is to consider you want to buy an item worth $10 but you only have $7. If the store owner lends you the difference, which you pay back later, then 7-10 = -3 is the amount of money on your balance sheet indicating you are in debt $3. The order of subtraction is important. Saying 10-7 = 3 shows a positive bank balance and you wouldn't be in debt (and still have $3 in your pocket).
=================================================
In either example, the value -3 is to the right of -5 on the number line so we would write the inequality -3 > -5 to say that -3 is larger than -5. Have a look at the image attached below.

[tex]x=7.5[/tex]
Step-by-step explanation:
If you look at the large triangle, you will see that the side [tex]x[/tex] is opposite of 30° angle and the side 15 is opposite of 90° angle (side opposite of 90° angle is called the hypotenuse).
We have the angle, we have the side opposite and the hypotenuse. Which trigonometric ratio relates opposite side and hypotenuse? SINE!
So we use the sin ratio and cross multiply and solve for [tex]x[/tex]:
[tex]Sin(A)=\frac{Opposite}{Hypotenuse}\\Sin(30)=\frac{x}{15}\\x=15*Sin(30)\\x=15*(0.5)\\x=7.5[/tex]
Hence, [tex]x=7.5[/tex]
Answer:

[tex]x=7.5\ un.[/tex]
[tex]y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]
[tex]z=\dfrac{15\sqrt{3}}{2}\ un.[/tex]
Step-by-step explanation:
Given triangle is special 30°-60°-90° right triangle. The leg that is opposite to the angle of measure 30° is always equal to half of the hypotenuse. The hypotenuse is of length 15 units, the leg that is opposite to the 30° angle is leg with length of x units, then
[tex]x=\dfrac{15}{2}=7.5\ un.[/tex]
In right triangle with hypotenuse x and legs y and a, angle opposite to the leg a is 30°, then
[tex]a=\dfrac{x}{2}=\dfrac{7.5}{2}=3.75\ un.[/tex]
and
[tex]b=15-a=15-3.75=11.25\ un.[/tex]
By the Pythagorean theorem,
[tex]x^2=y^2+a^2,\\ \\7.5^2=3.75^2+y^2,\\ \\y^2=\left(\dfrac{15}{2}\right)^2-\left(\dfrac{15}{4}\right)^2=\dfrac{225}{4}-\dfrac{225}{16}=\dfrac{675}{16},\\ \\y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]
In right triangle with legs y and b and hypotenuse z, leg y is opposite to 30° angle, then
[tex]z=2y=\dfrac{15\sqrt{3}}{2}\ un.[/tex]

[tex]2(x^2-6x)=-3\times 2[/tex]
step-2:
Simplify it
[tex]x^2-6x=-3[/tex]
step-3:
Add both sides 3^2
[tex]x^2-6x+3^2=-3+3^2[/tex]
now, we can complete square
[tex](x-3)^2=6[/tex]
step-4:
Take sqrt both sides
[tex](x-3)=-\sqrt{6},(x-3)=\sqrt{6}[/tex]
step-5:
Add both sides by 3
we get
[tex]x=3-\sqrt{6},x=3+\sqrt{6}[/tex]
