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:

missing number is a)0.01

Answer:

Answer is a) 0.01

Step-by-step explanation:

2500 times by 0.01 = 25

Answer:

82 revolutions    Step-by-step explanation:

One revolution will be the circumference of the tire, so multiply pi (3.1416) times the diameter (26 in.) to get 81.68 in. then round it up to 82.

Answer:

The answer is t/3=20

The right diagram is the one that has the orange boxes with 20s and has a t on top

Answer:

In 10 seconds it can swim 50 meters.

Step-by-step explanation:

Since 20 meters is 4 seconds, 40 meters is 8 seconds, and 10 meters is 2 seconds. In total 10 seconds. 50 meters.

Answer:

50m

Step-by-step explanation:

=20=4

x=10

Cris cross method

=20×10=4x

200=4x

x=200/4

x=50m

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%

This line is as close as possible to all of the points. Ideally, we'd want all the points to be on the same line, but this is the next best thing.

Something like line C is close to only the left-most point, while the other points are left out. Lines A and B are a similar story to line C.

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:

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:

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

Sequences are 46 so the answer is 46

Answer:

Step-by-step explanation:

area of rectangle=20×11=220 sq. cm.

area  of circle=π×4²=16π≈50.27 sq.cm

area of remaining rectangle=220-50.27≈169.73 sq.cm.

Answer: 207.44

Step-by-step explanation:

First you do 220-12.56= 207.44

Answer:

429 meters

half her maximum speed is 33 so multiply it by 13

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:

Ok so they had 100 cats in total so that mean each row meaning 1 row equals 5 cats so that mean's that 2, 3 or 4 didnt work.

Answer:

11/100

Step-by-step explanation:

11% =0,11

=11/100

[tex] \frac{11}{100} [/tex]

Answer:

1° you transform in 11/100, then you divide to get 0,11, then multiply to get 11 and this is the way you transform fraction in percentage

Step-by-step explanation:

Answer:

The answer is C because how much each girl paid for each pound of cherries has the variable C attached, and the rest of the money spent added to it. Also looking in the equation the sign tells us that they paid the same price for everything totaled in all.

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

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]

The spread is just the numbers you are counting to so like in number 1 it is 77 through 99, does that make sense? Hope this helps!

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:

4000 ft

-------------

minute

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
