22 minutes is spent doing aerobics and 38 minutes doing stretching
Let x represent the amount of time spent doing aerobics, Let y represent the amount of time spent doing stretching.
Since the goal is to do a 60-minute workout, hence:
x + y = 60 (1)
Also, 416 calories needs to be burnt hence:
12x + 4y = 416 (2)
We need to solve equation 1 and 2 simultaneously; multiply equation 1 by 4 and subtract the result from equation 2, hence:
8x = 176
x = 22 minutes
Put x = 22 in (1)
22 + y = 60
y = 38 minutes
Therefore 22 minutes is spent doing aerobics and 38 minutes doing stretching.

Answer:
[tex]\sqrt{28}[/tex]
Step-by-step explanation:
It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,
[tex](a)^2+(b)^2=(c)^2[/tex]
Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,
[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]

Answer:
Number 1: 1 2/4 or 1 1/2
Number 2: 2 4/6
Number 3: 5/6
Step-by-step explanation:
For Numbers 1 and 2... You'd have to separate the whole number from the fraction and subtract accordingly.
Number 1: 2-1=1 and 3/4-1/4=2/4
So you would get 1 2/4.
Number 2: 3-1=2 and 5/6-1/6=4/6
You would get 2 4/6
For Number 3 you would have to find the LCD (Least common denominator) for 1/2 and 2/3.
The answer will then be 5/6.
(I couldn't solve number 4 because it wasn't visible.)

The question says find the missing angles HELPP
Answer:
y: 71 degrees
z: 71 degrees
v: 71 degrees
x: 54.5 degrees
w: 54.5 degrees
Step-by-step explanation:
Ok, I might be wrong, please don't hate me!!!!
Since all triangles are 180 degrees, you can find all the measure while knowing only one angle measure.
To find y and z, you need to subtract 180 degrees by 38 degrees:
180 - 38 = 142
Since there are two angles, you need to divide the answer by 2.
142 / 2 = 71 degrees.
Since y and v are directly across from each other, they are the same measure (71 degrees).
With measures x and w, you do the same process of subtracting 180 by the value you know.
180 - 71 = 109
Then divide by 2.
109 / 2 = 54.5 degrees.

Find 5 Rational Numbers Between 1 and 2 using (a+b/2) where a=1 and b=2.
Answer:
There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.
As we have to find 5 rational numbers between 1 & 2
Take 5 and add 1 to it i.e. 5+1= 6
Now take the first number and multiply and divide it by 6 i.e.
1x6/6 = 6/6
Also take the second number and multiply and divide it by 6 i.e.
2x6/6= 12/6
This is done to convert 1 & 2 into rational number i.e. in form of p/q
Now we have two numbers 6/6 and 12/6 so five rational numbers between them are
7/6, 8/6, 9/6, 10/6, 11/6
The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.
There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal
Answer: 147.87 calories
Step-by-step explanation:
Let the amount of calories in 238.5 grams of this cereal be represented by x.
Based on the information given, we can form an equation as:
110/177.4 = x/238.5
Cross multiply
177.4 × x = 238.5 × 110
x = (238.5 × 110) / 177.4
x = 147.87
Therefore, there are 147.87 calories in 238.5 grams of this cereal.

Answer:
k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]
Step-by-step explanation:
|19 - 3k| = 3
-3k = 3 - 19
-3k = -16
k = 16/3
k = 5 1/3
-19 + 3k = 3
3k = 3 + 19
3k = 22

The location of four buildings on a coordinate grid are as follows:
Building 1 is at (−5, −3).
Building 2 is at (−5, 5).
Building 3 is at (4, 5).
Building 4 is at (4, −3).
A bike courier begins at building 1 and then delivers packages to building 2, then building 3, and then building 4. Then she bikes back to building 1. The path between each building is a straight line. One unit on the coordinate grid equals 100 feet.
What is the total distance the courier biked?
Enter your answer in the box.
Answer:
3400 feet
Step-by-step explanation:
Distance between building 1 and building 2 = |5+3| = 8
Distance between building 2 and building 3 = |4+5| = 9
Distance between building 3 and building 4 = |-3-5| = 8
Distance between building 4 and building 1 = |4+5| = 9
total distance = 8 x 2 + 9 x 2 = 34
total distance in feet = 34 x 100 = 3400 feet
Answer: 3400 feet

What are the coordinates of R'after a dilation by a scale factor of 3, centered
at the origin, followed by the translation (x, y) - (x + 4, y)?
A. (10,4)
B. (10, 12)
C. (10, 16)
D. (18,12)
Given:
The coordinate of point R in quadrilateral RUST are (2,4).
R is dilated by a scale factor of 3, centered at the origin, followed by the translation [tex](x, y)\to (x+4,y)[/tex].
To find:
The coordinates of R' after dilation and translation.
Solution:
If a figure is dilated by a scale factor of 3, centered at the origin, then
[tex](x,y)\to (3x,3y)[/tex]
We value R(2,4).
[tex]R(2,4)\to R_1(3(2),3(4))[/tex]
[tex]R(2,4)\to R_1(6,12)[/tex]
The rule of translation is:
[tex](x, y)\to (x+4,y)[/tex]
Using this rule, we get
[tex]R_1(6,12)\to R'(6+4,12)[/tex]
[tex]R_1(6,12)\to R'(10,12)[/tex]
Therefore, the coordinates of point R' are (10,12) and the correct option is B.

(2.5 * 6)/6.5
Step 1: Multiply 2.5 by 6 to get 15.
15/6.5
Step 2: Convert 6.5 into a whole number by multiplying it by 10. Make sure to do that to the 15 as well.
150/65
Step 3: 150/65 simplifies to 30/13 (GCF: 5).
30/13
Step 4: 30/13 becomes 2 4/13.
2 4/13
Step 5: 2 4/13 rounds to 2.3
2.3 is the value of x.
