How do we get .375 into a percent

Answers

You turn it into a percent by multiplying by 100 because a percent means out of a hundred so that's how you do it. You just multiply the decimal by 100.

percent is just multiplying 100 to the number,
so multiply 0.375 with 100
which gets you 37.5%

Sole x in the diagram 3x 75

Answers

Answer:

x=25

Step-by-step explanation:

Assuming you meant 3x = 75 what you want to do is isolate x. To isolate x you want to work backward. Since it is 3 times x you want to divide each side by 3 to get x on its own.

(3x)/3 = (75)/3

When you divide 3 and 3 you get one. 1x is represented by just an x so x=25.

Which fraction is equivalent to 6/9ths

A.18/36
B.3/4

D.1/3

Answers

$(6)/(9) = (6\cdot2)/(9\cdot2) = (12)/(18) \ \ \ \Rightarrow\ \ \ Ans.\ C$

the correct answer is c because if you divide 12/18 by 2 you will get 6/9.

What is the volume enclosed by the slanted prism in the diagram 225cm
270cm
300cm
540cm

Answers

To find the volume of a slanted prism, all you need to know is the area of the base and the height of prism. If you know these two things, then the volume of a prism can be calculated using formula

$V_(prism)=A_(base)\cdot H_(prism).$

Since $A_(base)=25 cm^2$ and $H_(prism)=9 cm,$ you have

$V_(prism)=25\cdot 9=225 cm^3.$

Answer: correct choice is A.

we know that
volume of the slanted prism is equal to
$V=B*h$
where
B is the area of the base------> $B=25 cm^(2)$
h is the height of the prism-----> $h=9 cm$
so
$V=25*9 \n V=225 cm^(2)$

the answer is the option
$225 cm^(2)$
