Answer:

Tennis, Badminton - 120 and if other sports are the same number it is 160

Step-by-step explanation:

Tennis, Badminton

600 * 1/5 = 120

Others

600-120 = 480

480/3 = 160

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

Answer:

44 miles

Step-by-step explanation:

He bikes 4 miles for every mile he runs so 11 times 4 = 44.

Answer:

b

Step-by-step explanation:

a)M=×50

b)30=1500

Step-by-step explanation:

30×50

=1500

Answer:

Positive

Step-by-step explanation:

Since x > 0 =  x is positive

Since y < 0 = y is negative

Product of positive and negative number is negative.

Therefore,

       xy = - xy

    - (xy) = -( -xy)

    - (xy) = xy              [since product of negative and negative is positive]  

Answer:

15 hundreds = star

Step-by-step explanation:

Move 1 thousand into hundreds place with the 5 hundreds that were already there. 5 plus 10 =15. We just don't usually think of it like that because of place value.

Answer:

I guess the answer is or the ★=2

Step-by-step explanation:

because if u add like now add 2+5=7,which is 7 tens in both side or 3 the one of thousand like 3+2 u get 5 the one of hundreds so that is how i get 2

Answer:

12

Step-by-step explanation:

16 times 0.75 = 12

Answer:

12

Step-by-step explanation:

75%=3/4.

So, we can simplify it to 3/4 of 16

4/4 of 16 is 16.

So, 3/4 of 16 is 1/4 less than that.

1/4 of 16 is 4. We want 3/4 so we multiply 4*3=12

Hope this helps!

Answer:

69.5

Step-by-step explanation:

A trapezoid's area is

[tex]\frac{b_1+b_2} {2} *h[/tex].

We know base 1 and base 2.

115+105=220.

220/2=110.

110*h=7645

7645/110=h

h=69.5

Answer:

First Question = 16 Second Question = 8

Step-by-step explanation:

First one

32+48=x(2+3)

80=5x

Divide each sides with 5 and you have x=16

Second one

32+48=4(x+12)

80=4x+48

subtract 48 from 48 and 80 and you have 32=4x.

Divide it with 4 both side and you have x=8

Answer:

The independent variable is the m, which is the number of minutes the hose has been running. The dependent variable is the g, which is the gallons per minute.

Answer:

g=36

Step-by-step explanation:

so if g=6m you would do 6x6 as 6 gallons per minute and g is the amount in the pool so you times them to get 35 so g=36

Step-by-step explanation:

Divide them up, and then after that, the parenthesis mean that you need to multiply them! So I hope that helps!

Answer:

Step-by-step explanation:

57) Order of operation: First what is inside the parenthesis - so division and then subtraction

For fraction division use KCF method

Keep the first fraction

Change division to multiplication

Flip the second fraction

[tex](\frac{5}{8}[/tex] ÷ [tex]\frac{1}{4})[/tex] - ([tex]\frac{4}{5}[/tex] ÷ [tex]\frac{1}{2})[/tex] = [tex](\frac{5}{8}*\frac{4}{1})-(\frac{4}{5}*\frac{2}{1})[/tex]

                      [tex]= (\frac{5}{2})-(\frac{8}{5})[/tex]

                      [tex]= \frac{5*5}{2*5} -\frac{8*2}{5*2}\\\\=\frac{25}{10}-\frac{16}{10}\\\\= \frac{9}{10}\\[/tex]

59)

[tex]\frac{3}{4} +\frac{1}{3} = \frac{3*3}{4*3}+\frac{1*4}{3*4}\\[/tex]

         [tex]=\frac{9}{12}+\frac{4}{12}\\\\= \frac{9+4}{12}\\\\= \frac{13}{12}[/tex]

[tex](\frac{3}{4}+\frac{1}{3})-\frac{9}{15}=\frac{13}{12}-\frac{3}{5}\\[/tex]

                    [tex]= \frac{13*5}{12*5}-\frac{3*12}{5*12}\\\\= \frac{65}{60}-\frac{48}{60}\\\\= \frac{65-48}{60}\\\\= \frac{17}{60}[/tex]

Answer:

12x + 8 = 12 x 6 + 8 = 80

8x-3 = 8 x 6 - 3 = 44

Step-by-step explanation:

(12x+8) + 55 + (8x-3) = 180 (Angle Sum Property)

(8+55-3) + (12x + 8x) = 180( group the variables)

(60) + (20x) = 180

20x = 180 - 60

20x = 120

x = 120/20 = 6

x=6

Answer:

It is the third option.

Step-by-step explanation:

Since when making an angle of 90º an equivalence is formed between the three points and when joining them the order of the figures is given.

Answer:

(42,48)?

Step-by-step explanation:

Answer:

(42, 27)

Step-by-step explanation:

The first rule is to do [tex]48-6[/tex], so this would be the x- axis.

The second rule is to do [tex]30-3[/tex], so this would be the y-axis.

The first ordered pair would be (48, 30), then the second ordered pair would be (42, 27).  

Answer:

42%

Step-by-step explanation:

I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:

(34+8)÷100×100 = 42%

Answer:

See below.

Step-by-step explanation:

Part A:

4(m + 3 + 5m) =

= 4m + 12 + 20m

4(m + 3 + 5m) =

= 4(6m + 3)

Part B:

Use the distributive property on the given expression to get the first expression.

4(m + 3 + 5m) =

= 4 * m + 4 * 3 + 4 * 5m

= 4m + 12 + 20m

Part C:

Let m = 2

a. Substitute 2 for m in the original expression:

4(m + 3 + 5m) =

= 4(2 + 3 + 5 * 2)

= 4(5 + 10)

= 4(15)

= 60

b. Substitute 2 for m in the second equivalent expression of part A.

4(6m + 3) =

= 4(6 * 2 + 3)

= 4(12 + 3)

= 4(15)

= 60

By substituting 2 for m, both expressions evaluate to 60.

We need to convert minutes to hours and ft to miles

60 minutes = 1 hour and 5280 ft  = 1 mile

4000 ft         60 minutes       1 mile

------------- * --------------- -----  * -----------

minute         1 hour                   5280 ft

45.454545 miles / hour

Answer:

Step-by-step explanation:

To find the slope we can use the slope formula

m = ( y2-y1)/(x2-x1)

 We know two points (0,0) and ( 1,4)

m = ( 4-0)/(1-0)

   = 4/1
