Consider the provided phrase.

Four times the sum of five and a number

Let the number is n and the sum of five and a number can be written as:

n+5

Thus, four times the sum of five and a number can be written as:

4(n+5)

Hence, the required expression is 4(n+5).

What is phrase in math?

In mathematics, we may use a phrase to describe an expression. When we describe an expression in words that incorporates a variable, we are doing so by using an algebraic expression. An example of this may be the phrase "greater than" (an expression with a variable).

run the numbers. to conduct a rational analysis of an issue. You can do the math because I was the last person to depart yesterday night and the first person to arrive this morning, and since only the overweight security guy was present. on April 7, 2005, by Dave L. Flag.

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour. What was their speed in pounds per hour.
allochka39001 [22]

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour.

1/3 of an hour is equal to 1/3 of 60 mins = 1/3 * 60 mins = 20 mins

We have to find their speed in pounds per hour( 60 mins).

Pounds of woods gathered in 1 hour or 60 mins = 15/20*60

= 15 * 3

= 45 pounds

Therefore, their speed in pounds per hour is 45 pounds / hour

Hope this helps ..!!

Thank you :)

The ratio of the width of a rectangle to it's length is 3:4. The length of the rectangle is 36 cm. Find the rectangles width.​
Fiesta28 [93]

Answer:

27 cm

Step-by-step explanation:

So the ratio you have is

width(x) : length (36)= 3:4

Divide 36 (length) by the ratio length. 36÷4=9

They are multiples of nine, so multiply the width by 9 to get the 3.

3×9=27

You have 27:36

If you want to check it, divide both by 9 and you get 3:4

What is the sum of the infinite geometric series? Sigma-Summation Underscript n = 1 Overscript 4 EndScripts (negative 144) (one-
11Alexandr11 [23.1K]

Step-by-step explanation:

∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹

This is a finite geometric series with n = 4, a₁ = -144, and r = ½.

S = a₁ (1 − rⁿ) / (1 − r)

S = -144 (1 − (½)⁴) / (1 − ½)

S = -270

If you wanted to find the infinite sum (n = ∞):

S = a₁ / (1 − r)

S = -144 / (1 − ½)

S = -288
