10. 156.25/6.25= 25 hrs
Answer:
9. x = 7, y = 10
Step-by-step explanation:
9. I first set up an equation x+y=17
then I set up a second equation y = x+3
I substitute y for x+3 and get x+x+3=17 or 2x+3=17
then I just evaluate the equation x=7
I then use my first equation x+y = 17 and substitute the value 7+y= 17 and get y = 10
10. Just divide 156.25 with 6.25 to get the number of hours she had to work to get 156.25 dollars. The answer would be 156.25/ 6.25 = 25

Answers
Answer:
The answer to the question is -1.32
Step-by-step explanation:
The first step will be to write out the equation that we are working with:
This equation is
[tex]0.2b + 0.6a = 12[/tex]
The next step is to write out the values of the figures that we are substituting:
[tex]a = -1.2 b=-3[/tex]
Substitution in mathematics can best be understood as "something being used in place of another thing". This means that wherever the first variable appears in an equation, the substituting values will replace it and multiply the number it is attached to.
In this case, we will replace the 'b' and the 'a' with the - 1.2 and - 3 respectively.
[tex]0.2(-3) + 0.6(-1.2) = -1.32[/tex]

Four basketballs and six baseballs cost $44. Five basketballs and four baseballs costs $48. Determine the cost for one basketball and one baseball.
Answers
Answer:cost for basket ball= $8 and
cost of baseball = $2
Step-by-step explanation:
Step 1
Let the cost of basket ball be represented as x
and cost of baseball = y such that
Four basketballs and six baseballs cost $44 will be expressed as
4x+ 6y= 44 --- eqn 1 also
Five basketballs and four baseballs costs $48 will be expressed as
5x+ 4y= 48--- eqn 2
Step 2
Having obtained two expressions we can now sole
4x+ 6y= 44 --- eqn 1
5x+ 4y= 48--- eqn 2
multiplying eqn 1 by 5 and eqn 2 by 4
20x+ 30y =220---- eqn 3
20x+ 16y=192-----eqn 4
subtracting equation 4 from 3 we now have
14y=28
y= 28/14
y=2 = $2
from equation 1
4x+ 6y= 44, putting the value of y=7 to find x
4x+ 6(2)= 44
4x+12= 44
4x= 44-12
4x=32
x= 32/4
x=8=$8
cost for basket ball= $8 and
cost of baseball = $2

mm long. Its area 9 is ...
(80 mm)(91 mm) = 7280 mm²
__
The two pieces of the net not accounted for above are the "flaps" above and below the central rectangle. Each of those two has an area of 40 mm by 5.5 mm, so their total area is ...
2(40 mm)(5.5 mm) = 440 mm²

What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔEFG
And , the measures of the sides of the triangle are
g = 4.3 cm
e = 9.1 cm
And , measure of angle ∠F = 116°
where c² = a² + b² - 2ab cos(C)
On simplifying , we get
a² = c² - b² + 2abcos ( C )
78.26 ( cos 116° ) - 4.3² - 9.1² = f²
f² = 135.7344
Taking square roots on both sides , we get
f = 11.7 cm
Hence , the length is f = 11.7 cm

PLS HELP The width of Ben's rectangular family
room is 3 feet less than the length.
The perimeter is 70 feet. What is the
length of the family room?
Answers
Answer:
19 feet
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of length and width by 2
width is 3 less than length so if we call the width x the length would be x + 3
2×(x + x + 3) = 4x + 6 and
4x + 6 = 70 subtract 6 from both sides
4x = 64 divide both sides by 4
x = 16
The length is x + 3 so the answer is 19 feet

A polygon has perimeter 12 units. It is dilated with a scale factor of 3/4. What is the
perimeter of its image?
A. 9 units
B. 12 units
C. 16 units
Answers
—————
With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.
Given that, the perimeter of a polygon = 12 units and the scale factor = 3/4.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
So, 3/4 = Dimensions of the new shape/12
= 3/4 × 12
= 3 × 3
= 9 units
With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.
