Ling walks 3/8 of the distance home from school in 9 minutes. She wants to know how long it will take her to walk the entire distance at the same speed. Ling uses the expressions 9 divided by 3/8 and 9 times 3/8 to find the answer. Explain what is wrong with Ling's expression and then write the correct solution.

Answer: 48.75

Step-by-step explanation:

Divide.

780/16=48.75

Answer:

1,120

Step-by-step explanation:

If you divide 280 and 5 you get 56. Then you multiply 56 and 20 and you get 1,120

Answer:

Given:

a + b = 9

=> a = 9 - b

Given:

a x b = 18

=> (9 - b) x b = 18

=> 9b - b^2 = 18

=> b^2 - 9b + 18 = 0

=> (b - 3)(b - 6) = 0

=> b = 3 => a = 6

=> b = 6 => a = 3

Hope this helps

Answer:

The answer would be 2/3.

Step-by-step explanation:

There are 6 faces on a dice 3 of which are odd which would be 1/2. Then there is one face on a dice that has 3 dots on it which would 1/6. So 1/2+1/6= 4/6 which simplifies to 2/3.

Answer:

1247.03

Step-by-step explanation:

if £1=$1.35

?=$125(crisscross them to get an answer.)

$125×£1÷$1.35=£92.59

if £1=$1.35

?=$6(crisscross to get an answer.)

$6×£1÷$1.35=£4.44

so you add them all up

£1150+£4.44+£92.59= £1247.03

Hey there!

The Distributive Property states that

a(b+c)=ab+ac

Where

a, b, and c can be

Now, let's simplify:

2(x+12)

multiply 2 times x and 2 times 12

2x+24

Hope everything is clear.

Answer:

YES

Step-by-step explanation:

57+45=102.

The triangle needs to have angles that add up to 180 so..

180-102=78

and that is the other degree instead of 45 on the other triangle

Step-by-step explanation:

Took the quiz

Answer:

0.019

Step-by-step explanation:

Here, we want to calculate the probability that 4 people selected at random have green eyes.

The probability of having green eyes = 0.37

Now, we are selecting 4 people and we want to calculate the probability that all have green eyes

That would be;

0.37 * 0.37 * 0.37 * 0.37 = 0.01874161 which is 0.019 to 3 decimal places

72 Pencils

24 calculators

72/24  = 3/1

for Every one calculator 3 Pencils need to be used

Greatest number of Package = 24 as 24 Calculators are there

number of pencils in each package = 3   ( 72/24 = 3)

Answer:

3 pencils will be in each package

Step-by-step explanation:

You divide 727272 by 242424 to get 3

Answer:

x = 64

Step-by-step explanation:

90 + x + 26 = 180

116 + x = 180

x = 180 - 116

x = 64

Answer:

x=64

Step-by-step explanation:

x and 26 are complementary, which means they add to 90 degrees.

x+26=90

We want to find x, so we have to get x by itself. 26 is being added on to x. To undo this, subtract 26 from both sides, because subtraction is the opposite of addition.

x+26-26=90-26

x=90-26

x=64

So, x is 64 degrees

Answer:

x = 73°

Step-by-step explanation:

a whole circle = 360°

so x + 50° + 91° + 2x = 360°

x+ 2x = 360°- 91° - 50°

3x = 219°

x = 219° ÷ 3

x = 73°

Answer:

16pi or approx. 50.26

Step-by-step explanation:

Since the diameter of each cookie is 8 cm, the radius of each cookie will be 4 cm. We can use the area of the circle formula (A = πr²), we can find that the area of each cookie is 16π, or around 50.26

Answer:

A = 16π

Answer: 8 times.

Step-by-step explanation:

I will answer in English:

This says:

The volume of a cube is 125cm^3

How many times the volume will increase if we duplicate the lenght of the side?

If L is the lenght of the side, we have that the volume of the cube is:

V = L^3

If we duplicate the lenght of the side, the new volume is:

V = (2*L)^3 = 8*L^3

So we can see that the volume of the new cube is 8 times the volume of the previous cube.

Now,  we can do the math, for our original cube we have:

L^3 = 125cm^3

L = 5cm

the new cube has L' = 2*L = 10cm

The volume of this cube is:

V' = L'^3 = 10cm^3 = 1000cm^3

the ratio V'/V is:

1000cm^3/125cm^3 = 8

Answer: I agree with Sita.

Step-by-step explanation:

An infinite number is a very big number which is impossible to physically achieve. I agree with Sita because when Rita is forming equations on and on to an extent of not knowing when to stop. That is when she can say to infinite. And I don't think this is possible.

Answer:

The volume of the prism is 27 cubic inches.

Step-by-step explanation:

In order to calculate the volume of the given prism, we need to apply the correct formula. The volume of the wedge prism is given by the following formula:

[tex]Volume = \frac{1}{2}*b*h*l[/tex]

Applying the data from the problem on the equation above, we have:

[tex]Volume = \frac{1}{2}*6*4.5*2\\Volume = 6*4.5\\Volume = 27[/tex]

The volume of the prism is 27 cubic inches.

Answer:

the volume of the sphere is

[tex]33.51 in^{3}[/tex]

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, sphere and cube.

Given data

Volume of cube v =   64 cubic inches

since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,

we know that volume of cube is expressed as

[tex]v= l*b*h[/tex]

[tex]v=l^{3}[/tex]

[tex]64= l^{3}[/tex]

[tex]l= \sqrt[3]{64}[/tex]

[tex]l= 4 in[/tex]

also diameter d=length l

Diameter d=  [tex]4in[/tex]

Radius r =  [tex]\frac{d}{2}[/tex]= [tex]\frac{4}{2}[/tex]= [tex]{2 in}[/tex]

Height h=[tex]4in[/tex]

we know that the volume of a sphere is given by

[tex]v= \frac{4}{3} \pi r^{3}[/tex]

substituting into the formula we have

[tex]v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}[/tex]

23 hours

Step-by-step explanation:

If you multiply 5 by 26 you get 130. So by doing a little math you can find that 23 times 5 is 115, so then you add 15 and there you go. You've got your answer.

Hope this helped!!! :)

Answer:

As I divided in the picture,

Total area = area of triangle + area of 2 rectangles          

                 =  base x height/2 + length1 x width1 + length2 x width2

                 = 15 x (15 + 3 + 5 - 3)/2 + 3 x 4 + 8 x (3 + 5)

                 = 226

Answer:

(X+2)power of 2 + (y + 3)power of 2 = 9    

Step-by-step explanation:

Answer:

[tex] (x + 2)^2 + (y + 3)^2 = 9[/tex]

Step-by-step explanation:

Center = (-2, - 3) = (h, k)

Radius (r) = 3

Equation of circle in centre radius form is given as:

[tex] (x - h) ^2 + (y - k) ^2 = r^2 \\

\therefore \{x - (-2)\}^2 + \{y - (-3)\}^2 = 3^2 \\
