Step-by-step explanation:

3y means 3 times y.  It is normally used to shorten an equation with a variable to save room.  The number is always placed before the variable.

Answers:

It's not clear which version of WX your teacher wants, so I provided both of them.

============================================================

Explanation:

Focus on the perimeters. The jump from 36 to 30 means the linear scale factor is 30/36 = 5/6

This means,

WX/YZ = 5/6

WX/5 = 5/6

6WX = 5*5

6WX = 25

WX = 25/6 which is exact

WX = 4.167 approximately

---------------

The linear scale factor is 5/6, so the area scale factor is (5/6)^2 = 25/36.

The area of figure 1 is 216 cm^2, making the area of figure 2 to be 216*(25/36) = 150 cm^2

Answer:

720°

Step-by-step explanation:

(180° x 6) - 360° = 720°

checking:

(right side) 2 angles 90° = 180°

(left side) 0ne pair of supplementary angles = 180°

(center) One angle  180° + ?°

             One angle  180° - ?°

             Equals 2 angles  180°

             Total = 720°

next time please double check your question because it took me a while to figure out 10204 was actually 1024!  

Answer:

32

Step-by-step explanation:

[tex] \triangle ABC \sim \triangle XYZ[/tex] (given)

[tex] \therefore \frac{AB}{XY} = \frac{BC}{YZ} [/tex] (csst)

[tex] \therefore \frac{68}{17} = \frac{a}{8} [/tex]

[tex] \therefore 4= \frac{a}{8} [/tex]

[tex] \therefore 4(8)= a [/tex]

[tex] \therefore a = 32 [/tex]

Answer:

60.5%

Step-by-step explanation:

60% white, 40% black

The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

Answer:

11.1

Step-by-step explanation:

We have the hypotonouse but need the opposite side

We will therefore use SOH

sin(68)=x/12

12sin(68)=x

x=11.1

Answer:

x=11.1

Step-by-step explanation:

12sin(68)

x=11.1

Answer:

5 1/10 c or 3 1/10 +2

When you simplify the expression, you combine like terms. 5 7/10 c and -2 3/5 c are like terms. You multiply two on the numerator and denominator to make it 6/10. You subtract 2 6/10c from 5 7/10c to make it 3 1/10. This next step is easy. 8 and -6 are like terms. So you subtract 6 from 8 to get two. The final step is optional. 3 1/10 + 2= 5 1/10

Answer: C

Step-by-step explanation:

Given

Nancy bought the bag with 1100 beads to make necklaces

She found another bag with 700 beads

So, the total number of beads is the sum of two i.e. 1800 beads

It takes 50 beads per necklace

The number of necklaces that can be formed is

[tex]\Rightarrow \dfrac{1800}{50}\\\\\Rightarrow 36\ \text{Necklaces}[/tex]

rate of blowing balloons of Alexa = 15/20 = 0.75

rate of blowing balloons of Sara = 18/25 = 0.72

rate of blowing balloons of Shirley= 16/21 = 0.76

rate of blowing balloons of Sam = 12/23 = 0.52

from above calculation we concluded Shirley can blow balloons at the fastest rate!

Answer:

188.53 m²

Step-by-step explanation:

Total area of the stage = area of the rectangle + area of the semicircle

Area of rectangle = Length * Width

Length = 16 m

Width = 5.5 m

Area of rectangle = 16*5.5 = 88 m²

Area of semicircle = ½(πr²)

r = ½(16) = 8 m

Area = ½(π*8²)

Area = 100.53 m²

Total area of the stage = 88 + 100.53 = 188.53 m²

Answer:

4)middle

5)77.0

Answer:

87.2º

Step-by-step explanation:

Complimentary angles total 90º

c + 2.8 = 90

c = 90 - 2.8

c = 87.2º

Answer:

Step-by-step explanation:

When angles are complementary, it means that they both add up to 90°.

In this case, one of the angles measures 2.8°.

So, to find the other one, we subtract 2.8 from 90.

90 - 2.8 = 87.2

The measure of the complementary angle is 87.2°
