Find the value of the expression below for r = 4 and t = 2
t^3 - r + 20 divided by r

Answers

Answer 1

Answer:

Answer:

The value of the expression $t^3-r+(20)/(r)$ is, 9

Step-by-step explanation:

Given: The expression $t^3-r+(20)/(r)$

Substitute the value of r=4 and t=2 in above expression to find its value;

$t^3-r+(20)/(r) = (2)^3-4+(20)/(4)$

Cube: the cube of a number t is its third power, the result of the number multiplied by itself twice. i.e, $t^3 = t * t * t$

Now, solve further we have;

$(2)^3-4+(20)/(4) = 8 -4+(20)/(4)$

Further, divide the number 20 by 4 we get the result 5 ;

⇒ 8-4+5 = 4+5 =9

Therefore, the value of the expression $t^3-r+(20)/(r)$ is, 9.

What is 9-4(2p-1)=45?

Answers

9 - 4(2p - 1) =45
5(2p - 1) = 45
10p - 5 = 45
10p = 45 + 5
10p = 50
p = 50/10
p =5 (ans)

9-4(2p-1)=45
5(10p-5)=45
10p-5=45
10(5)-5=45
50-5=45
45=45

B) 100
C) 1000
d) 10,000

Answers

The number should be multiply is 10.

What is multiplication?

In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The twofactors and the product are parts of a multiplication problem.

Given:

n=0.9

Now, there is one number behind decimal point.

So, we have to multiply it by 10 to convert it into fraction from decimal.

Thus,

10n = 0.9*10

10n = 9

n = 9/10

Hence, the number must be multiplied is 10
