Rewrite the equation 4x - 5y = 20 into slope-intercept form and graph it. ​

Answer:

Step-by-step explanation:

r = 3 in

h = 7 in

volume of cone = ⅓πr²h = 21π in³

cylinder has radius r = 3 and height h.

volume of cylinder = πr²h = 9πh in³

volume of cylinder is two times the volume of cone

9πh = 2×21π

9h = 42

h = 42/9 = 4⅔ in

Step-by-step explanation:

hi, use y=mx+b to help solve

the equation is y= 6x+30, 6 being the cost per t-shirt and 30 being the fee

substitute x for the values on the left in the table. for example, y=0x+30 would give the total cost of 0 t-shirts 30 dollars

for some reson i cant see it

Answer:

Total surface area = 132 square feet

Step-by-step explanation:

Surface area of the triangular prism = Area of the triangular bases + Area of the lateral rectangular sides

Area of the triangular surface = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                 = [tex]\frac{1}{2}\times 5\times 4[/tex]

                                                 = 10 square feet

Area of the rectangular side with dimensions 5ft by 7ft,

Area = 5 × 7 = 35 square feet

Area of the rectangular side with dimensions 7ft by 4ft,

Area = 7 × 4 = 28 square feet

Area of the rectangular side with dimensions 7ft by 7ft,

Area = 7 × 7 = 49 square feet

Total surface area = 2(10) + 35 + 28 + 49

                               = 132 square feet

Answer:

128 m squared

Step-by-step explanation:

Area of rhombus is

[tex] \frac{p \times q}{2} [/tex]

where p and q is the diagonal.

Rhombus's diagonals are equal to each other and bisect each other so just multiply the diagonal of one side by 2. and the other by 2 as well.

The horizontal diagonal is

8x2=16

The vertical diagonal is

8x2=16.

Plug those into the formula

[tex] \frac{16 \times 16}{2} [/tex]

[tex] \frac{256}{2} [/tex]

[tex]128[/tex]

Answer:

128m2

Step-by-step explanation:

8x8=64

64/2=32

32x4=128

Answer:

6.75cm

Step-by-step explanation:

The straw fits diagonally inside the can so it makes a right angled triangle with height and base of the can ( which is the diameter of the can)

So, hypotenuse = length of straw = 22.5cm

perpendicular = 18cm

base = diameter of can(d)

Using pythagoras theorem

h² = p² + b²

(22.5)² = 18² + d²

506.25 = 324 + d²

d² = 506.25 - 324

d² = 182.25

d = 13.5cm

Now radius = d/2 = 13.5/2 = 6.75cm

Answer:

3.44571

Step-by-step explanation:

The hundred thousands place is the fifth number after the decimal.

Answer:

3.44571

Step-by-step explanation:

The 5th number after the decimal is in the hundred thousandth place. to the right of the 0 in the hundred thousandth place there is an 8 which is greater than 4 so we round up the 0 is now a 1 and the rest of the numbers after it are gone

Answer:

13 years

Step-by-step explanation:

Given data

A=50,000

P=20,000

r= 7%

t=??

The compound interest formula is given as

A=P(1+r)^t

Calculate time, solve for t

t = ln(A/P) / r

t= ln(50000/20000)/0.07

t= ln(2.5)/0.07

t= 0.916/0.07

t= 13.0

Hence the time is 13 years

Answer:

x = 7

y = 4

Step-by-step explanation:

Measure of all the angles on right side triangle are equal. So, it is an equilateral triangle.

Therefore,

5y - 4 = 3x - 5..... (1)

Next, measure of two angles in the left side triangle are same, so it is an isosceles triangle.

Therefore,

y + 12 = 3x - 5......(2)

(By isosceles triangle property)

From equations (1) & (2)

5y - 4 = y + 12

5y - y = 12 + 4

4y = 16

y = 16/4

y = 4

Plug y = 4 in equation (2), we find:

4 + 12 = 3x - 5

16 + 5 = 3x

21 = 3x

x = 21/3

x = 7
