Answer:

Step-by-step explanation:

Givens

h = 14

b1 = 34

b2  = 45

Formula

A = (b1 + b2)*h /2                   Substitute into the formula

Solution

A = (34 + 45)*14/2                 Combine the brackets

A = (79) * 14/2                       Do the division

A = 79 * 7

Area = 553  cm^2

Answer:

616

Step-by-step explanation:

The equation to find the area of a trapezoid is:  A = ½ (b^1+b²) h.

b1=43

b2=45

h=14

Plug the variables in and solve.

A=\frac{1}{2} (43+45)14

A=\frac{1}{2} (88)14

A=\frac{1}{2} (1232)

A=616

Factor completely 6x - 18.<br> 6(x + 3)<br> 6(x-3)<br> 6X (-18)<br> Prime
8090 [49]

Answer:

6(x-3)

Step-by-step explanation:

the common number for 6 and 18 is 6 so if you extract that from the expression then it turns to 6(x-3) which cannot be factored further

Find the surface area of each figure (spheres and hemispheres)
xenn [34]

Answer:

7. 1520.53 cm²

8. 232.35 ft²

9. 706.86 m²

10. 4,156.32 mm²

11. 780.46 m²

12. 1,847.25 mi²

Step-by-step explanation:

Recall:

Surface area of sphere = 4πr²

Surface area of hemisphere = 2πr² + πr²

7. r = 11 cm

Plug in the value into the appropriate formula

Surface area of the sphere = 4*π*11² = 1520.53 cm² (nearest tenth)

8. r = ½(8.6) = 4.3 ft

Plug in the value into the appropriate formula

Surface area of the sphere = 4*π*4.3² = 232.35 ft² (nearest tenth)

9. r = ½(15) = 7.5 m

Surface area of the sphere = 4*π*7.5² = 706.86 m² (nearest tenth)

10. r = ½(42) = 21 mm

Plug in the value into the formula

Surface area of hemisphere = 2*π*21² + π*21² = 2,770.88 + 1,385.44

= 4,156.32 mm²

11. r = 9.1 m

Plug in the value into the formula

Surface area of hemisphere = 2*π*9.1² + π*9.1² = 520.31 + 260.15

= 780.46 m²

12. r = 14 mi

Plug in the value into the formula

Surface area of hemisphere = 2*π*14² + π*14² = 1,231.50 + 615.75

= 1,847.25 mi²

Jameson has 4300 in credit card debt with 14% interest that he wants to pay off in 24 months. He will need to make monthly payme
lakkis [162]

Answer:

Total cost of repayment  = 4955.04

Net interest paid = 655.04

Step-by-step explanation:

Given

Amount taken on loan = 4300

Repayment plan

Monthly installment= 206.46

Yearly installment  = 206.46 * 12 = 2477.52

Rate of interest per year = 14 %

Time Period for repaying the loan = 2 years

The total amount repaid by Jameson at the rate of 206.46 per month for next 24 months

= 206.46 *24\\= 4955.04

Net interest paid

= 4955.04 - 4300\\= 655.04

Total cost of repayment  = 4955.04

Net interest paid = 655.04
