A bookcase measures 13 ft wide and 24 ft tall. What would the bookcase's measurements be on a scale drawing using the scale 3 cm
qaws [65]

Answer:

19.5 cm wide

36 cm tall

Step-by-step explanation:

The given, 3 cm : 2 ft, is your first fraction (3 cm / 2 ft). We need to figure out how many cm is 13 ft and 24 ft. Let's start with 13 ft. We would use the first fraction, 3 cm / 2 ft, is equal to x cm / 13 ft. Then, you would cross multiply and get an answer of 19.5 cm. Now, we do the same thing but instead of 13 ft we need to use 24 ft. So again, 3 cm / 2 ft is equal to x cm / 24 ft. Then, cross multiply and get a final answer of 36 cm.

What are the factors of x2 − 64?
geniusboy [140]
Well, should be likee thiss correct meh if im wrong or what ever, but
 the answer would be, last one (x + 8)(x - 8), well 1, is because the 64 is a negative so if you would just take that 64 and bring it down then look at this onece the work is donee then when u add the 2 numbers that x would be x² or x2 n  that - 64 is that + 8 (-8) witch would equal out so if you really look at it the CORRECT ANSWER WOULD BE B. (x - 8)(x -8)

HELP PLEASE!
Archy [21]

Answer:

Option 2  50 ≤ s ≤ 100

Option 5 She could deposit $50

Option 6 She could deposit $75

Step-by-step explanation:

Let

s -----> amount of money Layla deposit into a saving account

we know that

25%=25/100=0.25

50%=50/100=0.50

so

s\geq 0.25*200 -----> s\geq \$50

s\leq 0.50*200 -----> s\leq \$100

The compound inequality is

\$50 \leq s\leq \$100

<em>Verify each case</em>

case 1) 25 ≤ s ≤ 50

The statement is false

see the procedure

case 2) 50 ≤ s ≤ 100

<u>The statement is True</u>

see the procedure

case 3) s ≤ 25 or s ≥ 50

The statement is false

Because is s ≤ 100 and  s ≥ 50

case 4) s ≤ 50 or s ≥ 100

The statement is false

Because is s ≤ 100 and  s ≥ 50

case 5) She could deposit $50

<u>The statement is true</u>

Because the value of s satisfy the compound inequality  \$50 \leq s\leq \$100

case 6) She could deposit $75

<u>The statement is true</u>

Because the value of s satisfy the compound inequality  \$50 \leq s\leq \$100
