Step-by-step explanation:

The number of miles Kianna trying to run by the end of the month is 40 miles.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Kianna is 75% of the way to achieving her goal and she has already run 30 miles.

Let the total number miles be x.

Now, 75% of x=30

75/100 ×x=30

0.75x=30

x=30/0.75

x=40 miles

Therefore, the number of miles Kianna trying to run by the end of the month is 40 miles.

Answer:

39.2 square units is the answer

Answer:I THINK THAT IT IS 60 DEGREES

Step-by-step explanation:

Answer:

Difference = 62.5 micrometer

Step-by-step explanation:

Given that:

Diameter of red blood cell = 7.5 micrometer

Diameter of coarse grain of sand = 70 micrometers

For calculating the difference between two diameters, we will subtract the diameter of red blood cell from diameter of grain of sand.

Difference = 70 - 7.5

Difference = 62.5 micrometer

Hence,

Difference = 62.5 micrometer

Answer:

120

Step-by-step explanation:

Here, we want to get the possible value of A

Now, we should understand that the value of an angle in triangle cannot be more than 180

Also, cosine can only be negative in the second and the 3rd quadrant

So,

arc cos (-0.5) = 120 , 300 , 60

But 60 is not correct as it will give a negative value

300 is not correct also as it is more than the angles present in a triangle

Thus, our answer is 120

Answer:

11 years

Step-by-step explanation:

in 11 years

Sam would be 13

and his mother would be 39

39/13 = 3

After 11 years, Sam would be 13 and his mother would be 39.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let the age of Sam's mother = M

Let the age of Sam = S

We are given that Sam is 2 yrs old, his mother is 28 yrs old.

According to the given condition

M = 3S

Then we can see that

39/13 = 3

Hence Sam would be 13 and his mother would be 39 years old.

Answer:

m∠B is 70°

Step-by-step explanation:

Knowing angle A is 40°, angles B and C combine for the remaining 140°. To figure out what angle B and C are (although this question asks for B, they could very well be the same, and this could be an isosceles triangle!), use the equation (2x - 30) + (x + 20) = 140.

(2x - 30) + (x + 20) = 140 (Combine 2x and x to get 3x.)

3x - 30 + 20 = 140 (Add -30 and 20 to get -10.)

3x - 10 = 140 (Add 10 to both sides. This undoes the -10.)

3x = 140 + 10 (Add 140 and 10 to get 150.)

3x = 150 (Divide both sides by 3. This undoes the multiplication by 3.)

x = 150/3 (Divide 150 by 3 to get 50.)

x = 50

Now that we know what x is, substitute x for 50 in the equation.

(2(50) - 30) + (50 + 20) = 140

(100 - 30) + (50 + 20) = 140

70 + 70 = 140

140 = 140

Both sides are the same, so x is 50, and angle B's (and C's!) measurement is 70°. (So, yes, as I had said, this is an isosceles triangle.)

Answer:

70

Step-by-step explanation:

70 students have a skateboard.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Total students are 125.

And to find the percentage of 56, we have to take the fraction.

56% of 125 students:

56 x 125 /100

= 7000/100

= 70

Therefore, 70 students have a skateboard.

Answer:

  [tex]\dfrac{2}{3}x-\dfrac{13}{12}=-\dfrac{5}{12}x[/tex]

Step-by-step explanation:

There are a couple of ways to get equivalent equations. We can collect the constants on one side of the equal sign, or we can collect the variable terms on one side of the equal sign.

Constants:

  [tex]\dfrac{2}{3}x-\dfrac{5}{6}=-\dfrac{5}{12}x+\dfrac{1}{4} \qquad\text{given}\\\\ \dfrac{2}{3}x-\dfrac{10}{12}-\dfrac{3}{12}=-\dfrac{5}{12}x \qquad\text{subtract $1/4=3/12$}\\\\ \dfrac{2}{3}x-\dfrac{13}{12}=-\dfrac{5}{12}x \qquad\text{matches last choice}[/tex]

Note that if we add 13/12 to this equation, the constant will be on the right, as in the second choice. However, that constant will be 13/12, not -7/12, so the second choice is not equivalent.

__

Variable terms:

  [tex]\dfrac{2}{3}x-\dfrac{5}{6}=-\dfrac{5}{12}x+\dfrac{1}{4} \qquad\text{given}\\\\ \dfrac{8}{12}x+\dfrac{5}{12}x-\dfrac{5}{6}=\dfrac{1}{4} \qquad\text{add $\dfrac{5}{12}x$}\\\\ \dfrac{13}{12}x-\dfrac{5}{6}=\dfrac{1}{4} \qquad\text{not equivalent to 3$^{\text{rd}}$ choice}[/tex]

Note that if we subtract 13/12x from both sides of this equation, the x-term will be on the right, as in the first choice. However, it will be -13/12x, not 1/4x, so the first choice is not equivalent, either.

The last offered choice is the equivalent equation.
