1636 cm^2

Step-by-step explanation:

cut in itwo two shapes a rectangle and isosceles trapizoid

Area - 1/2 hight(base x length)

1/2 x 14(6x17) = 714 cm^2

Area of rectangle- 2(wl x hl x hw) = 922 cm^2

l = 17

w = 13

h = 8

add the areas - 922 + 714 = 1636 cm^2

What's the Volume of this??

mr_godi [17]

Answer:

V = 90 cm^3

Step-by-step explanation:

The volume is given by

V = Bh

where B is the area of the base and h is the height

The base is the two sides that are identical, which is the triangle

B = 1/2 bh

= 1/2 (4*3)

= 1/2 (12)

= 6

Substituting into the volume equation, where h = 15

V = 6*15

V = 90 cm^3

1 7/10 x 2/3 what is the product

Ludmilka [50]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{1 \frac{2}{15}}}}}}$

Step-by-step explanation:

$\sf{1 \frac{7}{10} \times \frac{2}{3} }$

Convert the mixed number into improper fraction

$\longrightarrow{ \sf{ \frac{10 \times 1 + 7}{10} \times \frac{2}{3}}}$

$\longrightarrow{ \sf{ \frac{17}{10} \times \frac{2}{3}}}$

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term

$\longrightarrow{ \sf{ \frac{17 \times 2}{10 \times 3}}}$

$\longrightarrow{ \sf{ \frac{34}{30}}}$

$\longrightarrow{ \sf{ \frac{17}{15} }}$

Convert the improper fraction into mixed number

$\longrightarrow{ \sf{1 \frac{2}{15} }}$

Hope I helped!

Best regards! :D

Maddelein deposited $750 into an investment account that earns 1.5% daily compounded interest after year how much money will be

dimulka [17.4K]

1285.37

You can use the formula for compound interest:

P(1+R)^t

P = the principle, the amount of money

(1+R) = the rate, (%) as a decimal plus 1

^t = to the power of the number of years

Substitute the values:

750(1+0.08)^7

750(1.08)^7

1285.37
