Find the area for each trapezoid.​

Answer:

subtract 7 and then divide them

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.

Answer:

x = 2.3

Step-by-step explanation:

Since we know all three sides, what we do here is multiply side a & b's lengths together and divide by the hypotenuse. (a + b)/c

(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.

By observing the frequency polygon,

the number of 15 year old students who took part in the survey are 300.

A frequency polygon is almost identical to a histogram, which is used to compare sets of data or to display a cumulative frequency distribution. It uses a line graph to represent quantitative data.

To calculate the number of students, we add all frequency points corresponding to the time intervals.

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:

[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:

E and H are the correct answers

Step-by-step explanation:

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.

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

k = 22/3

k = 7 1/3

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.
