Answer:

a. 22.5 km

b. 267.52 m

c. 95 m

d. (4.2)(10^{-5}) km

Step-by-step explanation:

a. You can convert from hectometers to kilometers, and then you can make the multiplication:

\frac{5hm}{10}=0.5km

(3km)(0.5km)(15)=22.5km

b. You can convert from centimeters to meters, and then you can make the multiplication:

\frac{44cm}{100}=0.44m\\(19m)(0.44m)(32)=267.52m

c. You only need to divide 1,140 meters by 12:

\frac{1,140m}{12})=95m

d. You can convert from hectometers to kilometers, from decameters to kilometers and from meters to kilometers, and divide this by 15:

\frac{6hm}{10}=0.6km

\frac{7dam}{100}=0.07km

\frac{5m}{1000}=0.005km

\frac{(3km)(0.6km)(0.07km)(0.005km)}{15}=(4.2)(10^{-5}) km

astraxan [27]

Answer:

1 \frac{3}{4} cups

Step-by-step explanation:

Convert the numbers to decimals, then subtract the amount needed from the amount in the juice container:

4.25 - 2.5

= 1.75

This is equivalent to the fraction 1\frac{3}{4}

So, after Yupin makes the punch, there will be 1\frac{3}{4} cups of guava juice left in the container

Evaluate 4x3 + 2 for x = -1
Darina [25.2K]
4 {x}^{3} + 2

Plug in -1 for x

and you'll get this:
4 {( - 1)}^{3} + 2

Solve it further and you'll get:
4( - 1) + 2 \\ = - 4 + 2 \\ = - 2

Therefore,
4 {x}^{3} + 2
where x = -1
