10% of a number is 15
what is that number?

Answer:

40 degrees

100-60=40

Step-by-step explanation:

The angle x is in another angle that looks like 100 and 100 minus 60 is 40.

Hope this helps and if it is correct.

Answer:

Step-by-step explanation:

Remark

x + 60 together make up an angle that is vertically opposite the 100 degree angle.

Vertically opposite angles are equal.

Equation

x + 60 = 100

Solution and Answer

x + 60 = 100                    Subtract 60 from both sides.

x + 60-60 = 100 - 60      Combine

Answer: x = 40

Answer :D

8 [tex]\frac{2}{3}[/tex] (8 2/3)

Question explanation:

5 [tex]\frac{3}{4}[/tex] +  2 [tex]\frac{11}{12}[/tex] = [tex]\frac{26}{3}[/tex] = 8 [tex]\frac{2}{3}[/tex]

(5 3/4) + (2 11/12) = (26/3) = (8 2/3)

(5 + 2) + ( [tex]\frac{3}{4}[/tex] + [tex]\frac{11}{12}[/tex] )

(5 + 2) + (3/4 + 11/12)

7 + 3 x 3 + [tex]\frac{11}{12}[/tex]

   (4 x 3)  (11/12)

7 + [tex]\frac{9}{12}[/tex] + [tex]\frac{11}{12}[/tex]

(9/12) + (11/12)

7 + 9 + 11

      (12)

7 + [tex]\frac{20}{12}[/tex]

(7 + 20/12)

7 + (20 ÷ 4)

     (12 ÷ 4)

7 + [tex]\frac{5}{3}[/tex]

(5/3)

7 + 1 [tex]\frac{2}{3}[/tex]  

( 1 2/3)

= 8 [tex]\frac{2}{3}[/tex]

 (8 2/3)

8 [tex]\frac{2}{3}[/tex] = [tex]\frac{26}{3}[/tex] = 8 [tex]\frac{2}{3}[/tex]

(8 2/3) (26/3) (8 2/3)

Answer:

96 bricks

Step-by-step explanation:

Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour

Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.

rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)

To clarify, x=the normal rate

4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)

4(x-26)=[tex]2 \frac{11}{12}[/tex]x

x=96

Answer: 909.03

Step-by-step explanation:

We know that the equation is an exponential function, it can be written as y=ab^x

[tex]100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\[/tex]

[tex]\Rightarrow ab^1=11[/tex]

[tex]\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0[/tex]

[tex]\Rightarrow a=\frac{11}{b}[/tex]

a = 11/b, substitute it in equation 1

[tex]100 &=a b^{6.5}[/tex]

[tex]\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}[/tex]

[tex]\Rightarrow 100b=11b^\frac{11}{2}[/tex]

[tex]\Rightarrow 11\sqrt{b^{11} } =100b[/tex]

[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]

[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]

[tex]\Rightarrow {b^{11} } =\frac{10000}{121}}[/tex]

[tex]\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}[/tex]

[tex]\Rightarrow {b} = 1.49379[/tex]

a = 11/b

a = 11/(1.49379)

a = 7.36382

Equation: y = (7.36382)(1.49379)^x

Now plug in 12 for x:
[tex]\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}[/tex]

[tex]\Rightarrow 7.36382\cdot \:1.49379^{12}[/tex]

[tex]\Rightarrow 7.36382\cdot \:123.44530\dots[/tex]

[tex]\Rightarrow 909.03[/tex]

Therefore, f(12) = 909.03 for the exponential function

Answer: A and B.

Step-by-step explanation: The first option works because Clarissa is adding 64 fluid ounces of both orange and pineapple juice and 36 fluid ounces of apple juice which makes it an addition problem.  Option B works as well because it is similar to option A, only it shortens the problem by multiplying 64 twice, because 64 pops up twice.  Options C, D, and E don't work because it doesn't include taking away any juice or multiplying it in immense amounts, so that's why those are wrong.

Hope this helps! :)

We're given:

Let a represent the number of children who swam.

Let b represent the number of adults who swam.

Because we've set two variables, we need two equations to be able to find the answers.

One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.

Number of people:

[tex]a+b=478[/tex]

Price:

[tex]1.75a+2.25b=975[/tex]

We can solve this question using substitution, where we plug one equation into the other.

Isolate a in the first equation:

[tex]a+b=478\\a=478-b[/tex]

Plug the first equation into the second equation by replacing a:

[tex]1.75a+2.25b=975\\1.75(478-b)+2.25b=975[/tex]

Solve for b:

[tex]1.75(478-b)+2.25b=975[/tex]

⇒ Open up the parentheses:

[tex]836.5-1.75b+2.25b=975\\836.5-0.5b=975[/tex]

⇒ Subtract 836.5 from both sides to isolate b:

[tex]-0.5b=138.5[/tex]

⇒ Divide both sides by -0.5:

[tex]b=277[/tex]

Solve for a:

[tex]a+b=478[/tex]

⇒ Replace b with 277:

[tex]a+277=478\\a=201[/tex]

There were 201 children and 277 children at the pool that day.

Answer:

The top right one with the measurements 8mm x 8mm for the base and 10 mm for the slant height

Step-by-step explanation:

The net has a square base so that means the net forms a square based pyramid
Hope this helps :)

Answer:

The answer is the second figure on the top of the page.

Step-by-step explanation:

That's because the square is 8mm x 8mm

so the figure that has a square and 8mm x 8mm is the second one in the first row.

Answer:

First, set up equations for total cost for both Happy Paws and Woof Watchers.

x= number of hours

y= total cost

Happy Paws

y=3.50x +16

Woof Watchers

y=4.75x+11

4.75x+11=3.50x+16

x=4

You can check your answer by doing the following:

Happy Paws: (3.50)(4)+16= 30

Woof Watchers: (4.75)(4)+11= 30
