Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.

Answer:

[tex]a) x=15\\b) AD\ is\ not\ parallel\ tp BC[/tex]

Step-by-step explanation:

[tex]As\ we\ know\ that,\\Angle\ D=3x\\Angle\ A=2x\\Angle\ B=90\\Angle\ C=x\\The\ Angle\ Sum\ Property\ Of\ A\ Quadrilateral\ states\ that\ the\ sum\ of\ all\\ the\ interior\ angles\ of\ a\ quadrilateral\ is\ 180.\\Hence,\\ \angle D+ \angle A + \angle B + \angle C=360\\3x+2x+90+x=180\\3x+2x+x=180-90\\6x=90\\x=15\\Hence, x=15[/tex]

[tex]Hence,\\As\ Angle\ A\ and\ Angle\ B\ are\ co-interior\ angles, if\ they\ are\\ supplementary\ then\ AD \parallel BC.\ Lets\ check\ that\ out.\\Hence,\\Angle\ A=2x=2*15=30\\Angle\ B=90\ [Given]\\Hence,\\As\ 90+30\neq 180,\\Angle\ A +Angle\ B\neq 180\\Hence,\\As\ Angle\ A and\ Angle\ B\ are\ not\ supplementary, AD\ will\ not\ be\ parallel\ to\ CB.[/tex]

Answer:4%

Step-by-step explanation:

From the question, we are informed that a jigsaw puzzle is priced 17.00 but cost 17.68 at the register. This means that the sales tax is (17.68 - 17.00) = 0.68.

Therefore, the sales tax rate will be calculated as:

= (0.68 / 17.00) × 100

= 4%

The sales tax rate is 4%

Answer:

6+5

Step-by-step explanation:

Answer:

6+5

Step-by-step explanation:

If you ever have two negative signs together, like here, you get a positive sign. Here we have 6-(-5), the minus sign and the -5 are next to each other, creating a positive sign or turning the -5 into positive 5. This chart might help:

Answer:

y = 12x + -10

Step-by-step explanation:

sorry if its wrong i tried

Use the point-slope formula and then solve for y.

y - y_1 = m(x - x_1)

y_1 = 4

x_1 = 3

m = 3

y - 4 = 3(x - 3)

y - 4 = 3x - 9

y = 3x - 9 + 4

y = 3x - 5

Done.

Answer:

It took Anne 1/30 of an hour to bike 1 mile.

Step-by-step explanation:

Unit Rate - 30 miles/ 1 hour

[tex]\frac{30 miles}{1 hour} = \frac{1 mile}{? hour}[/tex]

Based on the visual above, we need to find the proportion.

30 miles divided 30 equals to 1 mile.

What is 1 hour divided by 30? Remember: whatever is done to the numerator must be done to the denominator!

1 divided by 30 equals 1/30. Since the unit is hour, the answer is 1/30 of an hour.

Step-by-step explanation:

Answer:

The length of the rectangle is 15 inches and the width is 33 inches

Step-by-step explanation:

The dimensions for the rectangle are as follows:

L=L and W=2L+3

The equation for perimeter of a rectangle is:

P=2l+2w

To Solve:

1. Plug values into perimeter equation

96=2(L)+2(2L+3)

2. Simplify the equation above.

96=2L+4L+6

3. Combine like terms:

96=6L+6

4. Solve for L by subtracting 6 from both sides:

90=6L

5. Solve for L by dividing both sides by 6:

15=L.

6. Plug 15 into the equation for the width:

2(15)+3=w

30+3=w.

Answer: d = 17

Step-by-step explanation:

d - 11 = 6

So, by adding 11 to each side you'd get rid of the -11 on the left and isolate the variable

d = 17

[tex]8y^3-6y\\2y(4y^2-3)[/tex]

Factor 2 out because both 8 and 6 can be divided by 2.

Factor y out because there are same y's in a polynomial.

Answer:

 2y (4y^2-3)

Step-by-step explanation:

8y^3 - 6y

Over here, we need to first look for the value they have in common

and u can identify that its "y". Now look for a no. that u can multiply both the no.s inside with. In this case, it two...but usually u need to pick the biggest value u can multiply both the no.s with.

So, now we need to put the common value outside the bracket-

2y (......)

2y * 4y^2 can give u 8y^3, therefore this will be the first value inside the bracket, the next value will be 2y*-3 coz it will give u -6y [Be careful of the signs].

So the ans would end up being-

2y (4y^2-3)
