Answer: Area= 18 cm; Perimeter: 18 cm

Step-by-step explanation:

1. Figure out the base and height:

Since the base is 3x-3; the height would be (3x-3)+3

2. Subsitute for x:

Base: 3(2)-3 => 6-3 => 3 cm

Height: (3(2)-3)+3 => (6-3)+3 => 3+3 => 6 cm

3. Figure out the Area:

A=b*h => A=3*6 => 18 cm

4. Figure out the perimeter:

P= 2b+2h => 2*3 + 2*6 => 18 cm

Brandee makes an hourly wage. In the last pay period, she earned $800 for regular hours and $240 for overtime hours. Her overtim

abruzzese [7]

Answer:

h = 13.333 +693.333/r

Step-by-step explanation:

For h hours, Brandee's pay will be ...

pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r

pay = 40r +1.5hr -60r . . . . . eliminate parentheses

pay = 1.5hr -20r . . . . . . . . . . collect terms

Solving for h, we have ...

pay +20r = 1.5hr . . . . . . . . . . add 20r

h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r

For the given pay of 800 +240 = 1040, we have ...

h = (1040 +20r)/(1.5r)

h = 13.333 +693.333/r . . . . . simplify to 2 terms

<em>Additional comments</em>

You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.

Please hurry and answer i am stuck on this question

Volume of prism = Area of cross-section × height

Volume of blue prism = ( $4 \frac{1}{8}$ )×( $h_B$

Volume of red prism = $( \frac{1}{2})(4 \frac{1}{8})$ × $(h_R)$

$V_{blue}:V_{red}$
$(4 \frac{1}{8})(h_B):( \frac{33}{16})(h_R)$
$\frac{33}{8}h_B: \frac{33}{16}h_R$
$\frac{66}{16}h_B: \frac{33}{16}h_R$
$66h_B:33h_R$
$66h_B = 33h_R$
$\frac{66}{33}= \frac{h_R}{h_B}$
$\frac{2}{1}= \frac{h_R}{h_B}$
$2:1=h_R:h_B$

The height of red prism is twice the height of the blue prism

Correct option: B

Solve the inequality<br> 7y+2<5y+12

Zanzabum

Answer:

y < 5

Step 1: Subtract 5y from both sides.

7y+2−5y<5y+12−5y

2y+2<12

Step 2: Subtract 2 from both sides.

2y+2−2<12−2

2y<10

Step 3: Divide both sides by 2.

$\frac{2y}{2}$ < $\frac{10}{2}$

= y < 5
