Fantom [35]3 years ago
4 0

Answer:

Step-by-step explanation:

Direct proportion

0.8 : 3.25 = 5.60: x

Product of Means = 3.25 * 5.60

Product of extremes =0.8*x

0.8*x=3.25*5.60

x = 3.25 * 5.60 / 0.8 = 3.25*56/8

x =3.25*7

x=$ 22.75

ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°, what is the value of m?
Digiron [165]

Answer:

The correct answer is option B.  17

Step-by-step explanation:

It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°

To find the value of m

From the figure we can see that, triangle WYZ is an isosceles  triangle.

ZW = ZY

Then <YXZ = <WXZ = 90°

It is given ∠YXZ  = (6m – 12)°

(6m – 12)° =  90°

6m = 90 + 12  = 102

m = 102/6 = 17

Therefore the value of m = 17

The correct answer is option B.  17

What is the interest earned on $3000 at a rate of 0.04 for three years? The formula is interest equals (principal) (rate) (time)
bekas [8.4K]

<u>Answer:</u>

The interest after 3 years is $360

<u>Explanation:</u>

Given the principal amount (P) = $3000

Rate of interest (R) = 0.04

Time period (T) is given as 3 years

The Simple Interest is calculated by the formula;

SI = Principal \times Rate of Interest \times Time

Substituting the values in the above formula,

SI = 3000 \times 0.04 \times 3

SI = $360

Therefore, the interest after 3 years is $360

Meredith is playing games at an arcade to earn tickets that she can exchange for a prize. She has 287 tickets from a previous vi
Zarrin [17]

if y=367

then you need to figure out this:

367=5x+287

so remove 287 from 367

367-287=80

Then divide by 5

80/5=16

so, x=16
