Answer:

Ratio is the proportion between two numbers.

Percent is the ratio times 100.

Rate is the change of a number per unit time.

Step-by-step explanation:

1.A rate refers to the frequency by which a certain event happens while a ratio refers to the relationship between the size, number, or degree of two or more things.

2.A rate is a comparison between two measurements of the same units while a ratio is the proportion of one thing to another.

3.A rate refers to the fixed quantity of two things while a ratio refers to the relationship between various things.

4.A ratio indicates the difference between things while a rate indicates the changes in their measurements or units.

5.A ratio is indicated by the quotient of one quantity divided by the other while a rate is indicated by the comparison between two things.

Hope it helped ! Have a nice day

Solve the system by substitution.<br> x + 6y = -2<br> -x= 3y - 10

TiliK225 [7]

Answer:

x = 22, y = -4

Step-by-step explanation:

x + 6y = -2 --- Equation 1

-x = 3y - 10 --- Equation 2

Equation 2 ×(-1): x = -3y + 10 --- Equation 3

Substitute x = -3y + 10 into Equation 1:

x + 6y = -2

-3y + 10 + 6y = -2

3y + 10 = -2

3y = -2-10

= -12

y = -12 ÷ 3

y = -4

Substitute y = -4 into Equation 3:

x = -3y + 10

x = -3(-4) + 10

= 12 + 10

x = 22

Solve for x

mr Goodwill [35]

Answer:

Option (2). x = 20°

Step-by-step explanation:

In the figure attached,

ΔABC is an equilateral triangle.

By the property of equilateral triangle, all sides of the triangle are equal and measure of all angles of the triangle is 60°.

By this property,

m∠B = 60°

and y = 46 - 16 = 30

By applying Sine rule in ΔBCD,

$\frac{\text{sin}60}{BD}=\frac{\text{sin}80}{46}=\frac{\text{sin}(\angle CBD)}{DC}$

$\frac{\text{sin}80}{46}=\frac{\text{sin}(\angle CBD)}{y}$

sin(∠CBD) = $\frac{30\times \text{sin}80}{46}$

= 0.6423

m∠CBD = 39.96

≈ 40°

m∠ABD = 60° - 40°

= 20°

Therefore, Option (2). 20° will be the answer.

If 75% of budget is 1200, what is the full budget using a table?

Alisiya [41]

Answer: full budget of 100% will be 1600

Step-by-step explanation:

If 75% = 1200

Full budget will be 100%

Represent the question as if 75% = 1200

Then 100% = x

Cross multiply:

75%x = 1200%

Divide both sides by 75%

x = 1200%/75%

x = 16 × 100

= 1600
