Answer:

The distance, D for the given expression is 70 miles

Step-by-step explanation:

Given as :

D = r t

r = 35 mi/ h

t = 2 h

Now, According to question

Distance = speed × Time

Where speed = r

Time = t

Distance = D

Now, from question

D = 35 miles per hour × 2 hours

So, D = 70 miles

Hence The distance, D for the given expression is 70 miles . answer

A chess club with 25 members is electing a new president. Abdul received 23 votes. What percentage of the club members voted for

cluponka [151]

Answer

92%

Explanation

23 out of 25 people voted Abdul.

So that means $\frac{23}{25}$ people voted Abdul.

When you divide 23 by 25 you get 0.92 which is 92% (multiply by 100).

You divide because a fraction means the numerator divided by the denominator.

please help. answer is 62.1m(squared) and the objects are composite! please show the work, no matter what i do i cant seem to ge

Answer:

$SA=62.1\ m^2$

Step-by-step explanation:

step 1

Find the surface area of the smaller rectangular prism

$SA=2B+Ph$

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

$SA=2[(2.5)(1.5)]+2(2.5+1.5)(1.5)$

$SA=7.5+12=19.5\ m^2$

step 2

Find the surface area of the cube

$SA=6s^2$

where

s is the length side of the cube

$SA=6(2.5^2)=37.5\ m^2$

step 3

Find the lateral area of the cylinder

$LA=\pi DL$

where

D is the diameter of the base

L is the length of cylinder

$LA=(3.14)(0.5)(3.5)=5.495\ m^2$

step 4

Find the area of the base of cylinder

$A=\pi r^{2}$

we have

$r=0.5/2=0.25\ m$ ----> the radius is half the diameter

$A=(3.14)(0.25)^{2}=0.19625\ m^2$

step 5

Find the surface are of the composite figure

we know that

The surface area of the composite figure is equal to the surface area of the smaller rectangular prism plus the lateral area of the cylinder, plus the surface area of the cube, minus the area of the two bases of cylinder

$SA=19.5+5.495+37.5-2(0.19625)=62.1\ m^2$
