Answer:

3 1/2 divided by 4

Step-by-step explanation:

Think about it.. "3 1/2 pizzas are divided between four friends" then you solve by turning the mixed number into a improper fraction, adding a one under the four because all numbers have a secret denominator of four, then you use KCF (Keep, Change Flip) which leads you to multiply the equation.

Hope this helps.

maxonik [38]

The volume of the cylinder by definition is given by:
V = Ab * h
Where,
Ab: base area
h: height
Substituting values we have:
140 = Ab * 12
To find the area, the first step is:
Pass the 12 dividing.

The graph shows the solution for which inequalities?

Helen [10]

Answer:

Inequalities are,

y ≥ 4x + 2

y ≥ 2

Step-by-step explanation:

Solid yellow line of the graph attached passes through two points (0, -2) and (1, 2).

Let the equation of this line is,

y = mx + b

Slope of the line = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

m = $\frac{2+2}{1-0}$

m = 4

Y-intercept 'b' = -2

Equation of the line will be,

y = 4x - 2

Since shaded area is on the left side of this solid line so the inequality representing this region will be,

y ≥ 4x - 2

Another line is a solid blue line parallel to the x-axis.

Shaded region (blue) above the line will be represented by,

y ≥ 2

Therefore, the common shaded area of these inequalities will be the solution of the given inequalities.

PLS HELP! URGENT!!!! A circular flower bed is 20 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the

krok68 [10]

Answer: Area of sidewalk is 217m²

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle

π is a constant whose value is 3.14

A circular flower bed is 20 meters in diameter.

radius = diameter/2 = 20/2 = 10 meters

Area of the flower bed = 3.14 × 10²

= 314m²

The circular flower bed has a circular sidewalk around it that is 3 meters wide. This means that the total diameter would be

3 + 20 + 3 = 26m

Radius = 26!2 = 13m

Total area = 3.14 × 13² = 530.66m²

Therefore, area of the sidewalk is

530.66 - 314 = 216.66

The area of sidewalk is 217m² to the nearest whole number

Question 10 (7 points) d Elizabeth borrowed $20,000 for five years at a 5% annual interest rate, what is her monthly payment, to

zhenek [66]

Answer:

monthly payment is $377

C is the correct option.

Step-by-step explanation:

The formula for the monthly payment is given by

$C=\frac{Prt(1+r)^n}{(1+r)^n-1}$

Given that,

P = $20,000

n = 5 years = 60 months

r = 0.05

Substituting these values in the formula

$C=\frac{20000\cdot \frac{0.05}{12}(1+\frac{0.05}{12})^{60}}{(1+\frac{0.05}{12})^{60}-1}$

On simplifying, we get

$C=\$377.425\\\\C\approx \$377$

Therefore, the monthly payment is $377

C is the correct option.
