Answer: It takes 3 seconds to do one of both i think
Step-by-step explanation:
19 and 6 was 75 and 18 and 6 was 72 which means 1 push up is 3 seconds multiply 3 by 18 that is 54 then subtract 72 by 54 which gives you 18 then divide 18 by 6 which is 3

Line x and line z are straight lines.
Which pair of angles are vertical?
Za and Zo
Zb and d
Za and Zb
Zc and Ze
Answer:
Zc and Ze
Step-by-step explanation:
The two angles are vertical because they are vertically aligned with line x. If you were to draw a line straight through the middle of them they would have an equal amount of space one each side.

For a given triangle it is known that cos A =-0.5, where 0°
Based on the information given above, the value of angle(s) A in standard position
could be
A)60°
B)120°
C)210°
D)300°
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

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.)

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.

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.
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.

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

Answer:
una stoy bien dias
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.
