If 56% of the 125 fifth-grade students have a skateboard, how many of the students have a skateboard?
Answer:
70
Step-by-step explanation:
70 students have a skateboard.
What is a percentage?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.

What is the measure of angle B in the triangle?
This triangle is not drawn to scale.
Enter your answer in the box.
m∠B=
°
A triangle labeled ABC with the angles A forty degrees, angle B parenthesis two x minus thirty parenthesis degree, angle C parenthesis x plus twenty parenthesis degrees
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:
[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.

Sam is 2 yrs old, his mother is 28 yrs old. In how many years will Sam's mother be 3 times as old as him
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.
What is the unitary method?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.

red blood cell is about 7.5 micrometers in diameter. A coarse grain of sand is about 70 micrometers in diameter. Find the difference between the two diameters.
need help plz
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

Step-by-step explanation:
The number of miles Kianna trying to run by the end of the month is 40 miles.
What is percentage?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.

The are in the rectangle below can be represented by 13x^2 - 4x + 10 and the area of the trapezoid can be represented by 9x^2 - 8x + 4. Write an expression to represent the area of the shaded region
Answer:
The area of shaded region
[tex]4x^2+4x+6[/tex]
Step-by-step explanation:
We are given that the area of rectangle
[tex]13x^2-4x+10[/tex]
The area of trapezoid represented by
[tex]9x^2-8x+4[/tex]
We have to find the expression to represent the area of the shaded region.
To find the area of shaded region we will subtract the area of trapezoid from the area of rectangle.
Therefore, the area of shaded region
Area of rectangle-Area of trapezoid

Isabel's shop sells 5 1/2 quarts of ice cream each day. How much is this in pints?
Answer:
13 pints.
Step-by-step explanation:
1 US liquid quart = 2 US liquid pint
6.5 quarts = how many pints?
Cross multiplying gives:
× 2 pints = 13 pints
Answer:
11 pints
Step-by-step explanation:
Each gallon is 4 quarts, and each quart is 2 pints. If a quart is 2 pints, then half a quart is 1 pint. Basically to convert, you just multiply the amount of quarts by two, and then that's the number of pints. 5 1/2 times 2 is 11, so 5.5 quarts is 11 pints.

First, make an equilateral triangle and label all the points. All the line segments that have a ratio of 1, mark those as congruent and all the line segments that have a ratio of 3, mark those congruent as well. Now, what we can is 3 congruent triangles by SAS, (AMK = BPM = CKP). Then, we take MP, PK, and KM and we know those are congruent because of CPCTC. That means all the sides are equal in the inner triangle which means it is an equilateral triangle.
