If the ratio of the length of a rectangle to its width is
9/4 and it’s length is 18 cm, what is the width of the rectangle?
9514 1404 393
Answer:
8 cm
Step-by-step explanation:
It is convenient to write the proportion with the unknown (width) on top:
width/length = 4/9 = w/(18 cm)
Multiplying by 18 cm gives ...
w = (18 cm)(4/9) = 8 cm
The width of the rectangle is 8 cm.
Answer:
The answer is 8.
Step-by-step explanation:
I did a test with this question on it.
This was the correct answer.
YOUR WELCOME!!! HOPE IT WAS HELPFUL :)
Tell whether each statement is True or False.
a. 2(3 - 4y) = 6 - 4y
b. 3 + 5/9 + 2n) = 48 + 5n
c. 9 - 3ly - 2) = 3 - 3y
d. 3(6x - 2) - 7 = 18x - 13
Answer:
a. FALSE
b. FALSE
c. FALSE
d. TRUE
Step-by-step explanation:
Statement a.
2 (3 - 4 y) = 6 - 4 y
use distributive property on the left:
6 - 8 y which is NOT 6 - 4 y then, FALSE statement
Statement b.
3 + 5 (9 + 2 n) = 48 + 5 n
apply distributive property on the left:
3 + 45 + 10 n = 48 + 10 n which is NOT 48 + 5 n then , FALSE statement
Statement c.
9 - 3 (y - 2) = 3 - 3 y
apply distributive property on the left:
9 - 3 y + 6 = 15 - 3 y which is NOT 3 - 3 y then, FALSE statement
Statement d.
3 (6 x - 2) - 7 = 18 x - 13
apply distributive property on the left:
18 x - 6 - 7 = 18 x - 13 which IS the same as 18 x - 13 then , TRUE statement

Step-by-step explanation:
book is 6 inches wide and 9 inches tall. A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. A publisher wants to use a scale factor of 1.5 to enlarge a book. What will the area of the front of the book be after the book is enlarged? 54 in2 81 in2 121.5 in2 78.75 in2
Answer:
6x1.5=9
9x1.5=13.5
9x13.5=121.5
Step-by-step explanation:
Answer: 121.5 in²
Step-by-step explanation: If you multiply the width (6 in.) by 1.5 to scale is up you get 9 in. and if you do the same with the length (9 in.) you get 13.5 in. ... You can then calculate the area.

Answer:
B: 2 32/48
Step-by-step explanation:
8 4/8 - 5 5/6
Turn to fractions:
8 4/8 = 68/8
5 5/6 = 35/6
Common denominator: 24
68 x 3 = 204
8 x 3 = 24
35 x 4 = 140
6 x 4 = 24
Set-up:
204/24 - 140/24
Solve:
64/ 24
Simplifying to Mixed Number:
64/24 = 8/3 = 2 2/3 = 2 32/48

A 15 meter long cylinder with a diameter of 7 meters has a square prism with a base length of 4 meters hole going all the way through the center of it as shown in the diagram (not to scale). Find the volume of the composite shape rounding to the nearest cubic meter.
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.

Round 4,287,965 to the nearest thousand
Answer:
It is 4,288,000.
Step-by-step explanation:
To round to the nearest thousand, you need to find the thousands place. In the thousands place there is a "7". Okay, we've found it, so the next step is rounding.
To round, there is a handing phrase that we can use to know whether we should round the place up or down. It is "4 or less, let it rest. 5 or more, add 1 more." We need to apply this phrase to the number behind the place we need to round (so apply it to the place behind the thousands place).
When we look behind the thousands place, we see there is a 9. Apply the rule to that. Since 9 is above 5 and not less than 4, we need to add one more to the thousands place.
That means after we round, the 7 turns into a 8. That's how you get 4,288,000.
Hope this makes sense <3

If f(x) = 2 + x and g(x) = 3 - x, what is go f(-1)?
Answer:
g(f(-1)) = 2
Step-by-step explanation:
f(x) = 2 + x
g(x) = 3 - x
if you need to find g(f(-1)); find f(-1) first
f(-1) = 2 + (-1) = 1
f(-1) =1; now plug this into g(1)
g(1) = 3 - 1 = 2
