Geometry, Chapter 9 test

Answer:

B

Step-by-step explanation:

Answer:

E = 12.20(h) - 7.15

h = 6.82 hours

Given:

Pay hour = $12.20 per hour

Bus fare = $7.15

1.Equation:

Assume

She has work for "h" hours

Total earning = E

So,

E = 12.20(h) - 7.15

If,

Total earning = E = $90.45

So,

E = 12.20(h) - 7.15

90.45 = 12.20(h) - 7.15

h = 6.82 hours

Answer:

4/4 its so eassy look at the triangle its give me answer

Answer:

C. -1

Step-by-step explanation:

Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:

y = mx + b

-7 = -3(2) + b

-7 = -6 + b

-1 = b

So, the y intercept is -1.

The correct answer is C. -1

I think you put the number 2

Answer:

1)6

2)20

3)45

Step-by-step explanation:

a=1/2 bh

1) 4*3=12/2=6

2) 8*5=40/2=20

3)15*6=90/2=45

Answer:

1) 6

2) 20

3) 45

Step-by-step explanation:

To find the area of a triangle, use the formula [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the base, and [tex]h[/tex] represents the height. In the first triangle, the base length is 4 and the height is 3, so the area is 6. In the second triangle, the base length is 5 and the height is 8, so the area is 20. In the third triangle, the base length is 15 and the height is 6, so the area is 45.

Answer:

The answer is 85 degrees.

Step-by-step explanation:

This is because all four interior angles of the rectangle should add up to 360 degrees. So 360-85-95-95 equals 85.

Answer:

4,000 miligrams

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

For 3 serving saffron required = 2 grams

So, for 6 (3×2)servings saffron required = 2 × 2grams

= 4 grams

As we know that,

1 gram = 1,000 milligrams

So, 4 grams = 4 × 1,000 milligrams

= 4,000 miligrams

Hence, 4,000 miligrams of saffron would be needed for 6 servings.

Answer:

I would say around 45% chance it is in there while I'm just assuming because the circle is just a little less than half the square

Answer:

Total cost of footpath = 528 m²

Step-by-step explanation:

Width of footpath is 2m.

Thus,

For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²

For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²

Total area = 112 + 64 = 176 m²

cost to tile foot path is $3 per square metres.

Total cost of footpath = 176 × 3

Total cost of footpath = 528 m²

Answer:

5 months

Step-by-step explanation:

Given

[tex]c = 30m + 50[/tex]

[tex]c = 20m + 100[/tex]

Required [Missing from the question]

At what month will the cost be equal

To do this, we equate both expressions

[tex]c = c[/tex]

This gives:

[tex]30m + 50 = 20m + 100[/tex]

Collect like terms

[tex]30m - 20m = 100 - 50[/tex]

[tex]10m = 50\\[/tex]

Solve for m

[tex]m = \frac{50}{10}[/tex]

[tex]m = 5[/tex]

Answer:

D: 40 degrees

Step-by-step explanation:

if the arc going from B to A to C is 320 degrees then 40 degrees is added to that to make 360 degrees so it is 40.

Answer:

6a - 6b + 24

Step-by-step explanation:

Use the distributive property to multiply 6 to the values given in the parentheses.

6(a - b + 4)

6 x a = 6a

6 x - b = 6b

6 x 4 = 24

Combine them:-

=> 6a - 6b + 24

Step-by-step explanation:

Answer:

125 is the correct answer because sum of two opposite interior angles is equal to exterior angle

Complete question is;

Which properties are necessary to claim that the two prisms are congruent? Check all that apply.

1) The lengths of corresponding edges are in a 1:1 ratio.

2) The volumes are equal.

3) Corresponding angles have different measures.

4) Corresponding faces are not congruent.

5) The base areas are equal.

6) The prisms have the same height

Answer:

1) The lengths of corresponding edges are in a 1:1 ratio

2) The volumes are equal.

5) The base areas are equal.

6) The prisms have the same height

Step-by-step explanation:

For two prisms to be congruent, it means they are similar with the following properties;

Each pair of their corresponding angles must be the same.

Each pair of their corresponding lengths must have same ratio.

The ratio of their corresponding lengths will have to be 1:1

Also, they must have same volume and same height.

Thus, looking at the options, the correct ones are 1,2,5,6

Answer:

C

Step-by-step explanation:

Te unoccupied volume (V) of the cube is calculated as

V = volume of cube - volume of sphere

   = 7³ - [tex]\frac{4}{3}[/tex] πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )

   = 343 - [tex]\frac{4}{3}[/tex] π × 3,5³

   = 343 - [tex]\frac{4}{3}[/tex] π × 42.875

   = 343 - 179.59438

   = 163.4....

    ≈ 160 cm³ ( to the nearest 10 cm³ )
