AfilCa [17]
Four of the 7 students got a sticker, so you need to turn that into a percent. To do that, divide 7 by 4, which gives you .57. That means that 57% of students got a sticker.

**HELP**<br>find the angle measures given the figure is a rhombus.​
DIA [1.3K]

Answer:

m<1=74

m<2=37

Step-by-step explanation:

m<2 is the same as the other angle, 37 degrees. So now we need to find the other angle in the triangle.

37+37+x=180.

The total degree of a triangle is 180.

x=106

Subtract that from 180 to get m<1.

180-106=74

I hope this helps!

Good luck!

Can u guys PLEASE answer this question ASAP. THIS IS EXTREMELY URGENT
Ulleksa [173]

Answer:

The answer to your question is $56  

Step-by-step explanation:

Data

Payment before noon = $11.20

Payment after noon = $11.20/2

Time from 9:00 to 16:00

Process

1.- Calculate the hours worked before noon and the hours worked after noon.

    Before noon = 12:00 - 9 = 3 hours

    After noon = 16:00 - 12:00 = 4 hours

2.- Calculate the payment

Payment = (3 x 11.2) + (4 x 11.2/2)

               = 33.6 + 22.4

               = $56

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is
vampirchik [111]

we know that A has 60% of salt, so if way we had "x" amount of ounces of A solution the amount in it will be 60% of "x", or namely (60/100)*x = 0.6x.

Likewise for solution B if we had "y" ounces of it, the amount of salt in it will be (75/100) * y or 0.75y, thus

\begin{array}{lcccl} &\stackrel{solution}{quantity}&\stackrel{\textit{\% of }}{amount}&\stackrel{\textit{oz of }}{amount}\\ \cline{2-4}&\\ A&x&0.60&0.6x\\ B&y&0.75&0.75y\\ \cline{2-4}&\\ mixture&60&0.65&39 \end{array}~\hfill \begin{cases} x+y=60\\ 0.6x+0.75y=39 \end{cases} \\\\\\ \stackrel{\textit{since we know that}}{x+y=60}\implies y = 60 - x~\hfill \stackrel{\textit{substituting on the 2nd equation}}{0.6x+0.75(60-x)=39}

0.6x+45-0.75x=39\implies -0.15x+45=39\implies -0.15x=-6 \\\\\\ x = \cfrac{-6}{-0.15}\implies \boxed{x = 40} \\\\\\ \stackrel{\textit{we know that}}{y = 60 - x}\implies y = 60-40\implies \boxed{y = 20}
