PLEASE HELP!!! The right rectangular prism is packed with unit cubes of the appropriate unit fraction edge lengths. Find the vol

never [62]

--------------------------------------------------
Formula :
--------------------------------------------------
Volume = Length x Width x Height

--------------------------------------------------
Find volume :
--------------------------------------------------
$\text { Volume = } 4\dfrac{1}{4} \times 5 \times 2$

--------------------------------------------------
Change to improper fractions :
--------------------------------------------------
$\text { Volume = } \dfrac{17}{4} \times \dfrac{5}{1} \times \dfrac{2}{1}$

--------------------------------------------------
Combine into single fraction :
--------------------------------------------------
$\text { Volume = } \dfrac{170}{4}$

--------------------------------------------------
Simplify:
--------------------------------------------------
$\text { Volume = } 42 \dfrac{1}{2} \ cm^3$

--------------------------------------------------
Answer: Volume = 42 1/2cm³ (Answer c)

6b < 36 or 2b + 12 > 6

Step2247 [10]

Answer:

-3 < b < 6

Step-by-step explanation:

6b < 36 or 2b + 12 > 6

b < $\frac{36}{6}$ or 2b > 6 - 12

b < 6 or b > -3

Simplifying this becomes;

-3 < b < 6

Can anyone help me with this problem ?

Elena L [17]

Come now ! I'm sure you could unravel it if you look at it and think about it
for a minute or two.

What's an angle bisector ? It's a line that splits an angle exactly in half.
The two little angles on each side of it are EQUAL. Each of them is exactly
half of the big angle.

So in this drawing, (3/2 x - 6) is equal to (1/4 x + 4) .
Do you think you could find 'x' ?

3/2 x - 6 = 1/4 x + 4

Add 6 to each side of the equation: 3/2 x = 1/4 x + 10

Multiply each side by 4 : 6 x = x + 40

Subtract 'x' from each side: 5 x = 40

Divide each side by 5 : x = 8

Angle CBD is 1/4 x + 4 . That's 1/4 (8) + 4 = 2 + 4 = <u>6 degrees </u>

∠R and ∠S are complementary. If m∠R = (2x+7) and m∠S = (4x - 13), find m∠R

____ [38]

Answer:

m∠R = 39 degrees

Step-by-step explanation:

As complementary angles add up to 90 degrees, we can set up an equation to get x then find the measure of ∠R:

m∠R + m∠S = 90

2x+7+4x-13=90

6x+7-13=90

6x-6=90

6x=96

x=16

Since m∠R = (2x+7), 2x+7 would be 2(16)+7 or 39 degrees. So in conclusion, m∠R = 39 degrees

What is the smallest whole number that is a multiple of 5, 9, and 12?

Marianna [84]

Answer:180

Step-by-step explanation:

you start by finding the prime factorization of the number

5=1*5

9=3*3

12=2*2*3

the shortest way to find the factors is to find is most of them like example, at max, there are 2 two's, 2 three's and 1 five then you multiply them all together

4*9*5=180 and that's the answer
