Step-by-step explanation:

Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)

area of triangle = 1/2 x 20 x (16-7) = 90cm^2

area of rectangle = 20 x 7 = 140cm^2

total area = 90 + 140 = 230cm^2

A road crew can pave 2/5 km in 1 1/2 hours.how many km of road can they pave in 10 hours?

andrey2020 [161]

Answer:

8/3 km

Step-by-step explanation:

we can represent the given information on a table:

Kilometers time (hours)

2/5 ⇔ 1 1/2

and since we want to know how many kilometers (x) will be paved on 10 hours:

Kilometers time (hours)

2/5 ⇔ 1 1/2

x ⇔ 10

The relationship these 3 numbers have can be described by using the <u>rule of three,</u> which is to multiply the cross quantities on the table (2/5 by 10) and then divide by the remaining amount (1 1/2):

x = $\frac{2}{5}*10$ ÷ $1\frac{1}{2}$

x = $\frac{20}{5}$ ÷ $1\frac{1}{2}$

we use $1\frac{1}{2}=\frac{3}{2}$

x = $\frac{20}{5}$ ÷ $\frac{3}{2}$

and we make the division:

x = $\frac{20}{5}$ ÷ $\frac{3}{2}$ = $\frac{20*2}{5*3}=\frac{40}{15}$

we simplify the fraction by dividing the numerator and denominator both by 5, and we get the result:

x = $\frac{8}{3}$

thus, in 10 hours the crew will pave 8/3 km. Which is about 2.66 km.

For each right triangle below, find all unknown side lengths and angle measures:

vlabodo [156]

Answer:

10.

here,

h=c

b=5

p=12

,we know that,

h²=b²+p²(pythagoras theorum )

c=5²+12²

c=25+144

c=169

hence the value of c is 169.

Which expression is equivalent to (m8n-4) 1/4

ser-zykov [4K]

Answer:

D. $\dfrac{m^2}{n}$

Step-by-step explanation:

I assume this is your problem:

$(m^8n^{-4})^{\frac{1}{4}}$

If so, then this is the solution.

$(m^8n^{-4})^{\frac{1}{4}} =$

$= m^{8 \times \frac{1}{4}} n^{-4 \times \frac{1}{4}}$

$= m^2 n^{-1}$

$= \dfrac{m^2}{n}$
