Can someone help me with this question

Answer:

1 ) m∠ 1 = 72°, m∠2 = 108°,

2 ) m∠ 1 = 22.5°, m∠2 = 67.5°

Step-by-step explanation:

Question 2 ) Assuming these are supplementary angles, we know that their measures form a linear pair that add to 180°;

let us assign these angles as 1, and 2 ⇒ m∠ 1 + m∠ 2 = 180,

with the given ratios 2 to 3, we can say x ⇒ one part of measure, so that ⇒ 2x + 3x = 180,

2x + 3x = 180 ⇒ combine like terms,

5x = 180 ⇒ divide either side by 5,

x = 36°

If this is so, m∠ 1 = 2x = 2 * ( 36 ) = 72°, and m∠ 2 = 3x = 3 * ( 36 ) = 108°;

Solution; m∠ 1 = 72°, m∠2 = 108°

Question 3 ) If it is known that two angles are complementary to one another, we can say their measures add to 90°;

let us one more, assign these angles as 1 and 2 ⇒ m∠ 1 + m∠ 2 = 180,

knowing that the measure of one angle is 3 times that of the other angle we can derive the ratio 1 : 3 in the manner smaller ∠ measure : bigger ∠ measure so that ⇒ x + 3x = 90,

x + 3x = 90 ⇒ combine like terms,

4x = 90 ⇒ divide either side by 4,

x = 22.5

If this is so, m∠ 1 = x = 1 * ( 22.5 ) = 22.5°, and m∠ 2 = 3x = 3 * ( 22.5 ) = 67.5°;

Solution; m∠ 1 = 22.5°, m∠2 = 67.5°

Answer:

Area of rectangle PLUM = 75.00 square units

Step-by-step explanation:

Since diagonal of rectangle divides the rectangle into two equal triangles,

Therefore, area of the rectangle PLUM = 2× area of triangle PLM

By the mean proportional theorem,

In ΔPLM,

AP² = AM × AL

6² = AM × 8

AM = [tex]\frac{36}{8}[/tex]

AM = 4.5 units

Area of PLM = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

                     = [tex]\frac{1}{2}(ML)(AP)[/tex]

                     = [tex]\frac{1}{2}(8 + 4.5)(6)[/tex]

                     = 12.5 × 3

                     = 37.5 units²

Now area of rectangle PLUM = 2×37.5 = 75 units²

Therefore, area of the rectangle is 75.00 square units.

Step-by-step explanation: Khan Academy

Work Shown:

x = 108 is the raw score we want to transform

mu = 104 is the mean

sigma = 1.9 is the standard deviation

z = (x-mu)/sigma

z = (108-104)/1.9

z = 4/1.9

z = 2.10526315789473 which is approximate

z = 2.11 rounding to two decimal places

I'm rounding to two decimal places because many z tables will work with this level of precision.

The total number of horses he had at first was 7 horses.

Word problems in mathematics involve careful understanding and they are those methods we use in solving real-life cases by using:

From the given information:

Then, we can have the system of equations for the three cases to be:

[tex]\mathbf{\dfrac{1}{2}x + \dfrac{1}{2}y = 3 ---- (1)}[/tex]

Making (y) the subject and ignoring (x), we have:

[tex]\mathbf{y = \dfrac{3 - \dfrac{1}{2}}{\dfrac{1}{2}} = 5}[/tex]

y = 5

For the second man;

[tex]\mathbf{\dfrac{1}{2}z + \dfrac{1}{2}y = 3 ---- (2)}[/tex]

[tex]\mathbf{z= \dfrac{3 - \dfrac{1}{2}(5)}{\dfrac{1}{2}} = 1}[/tex]

z = 1

For the third man:

[tex]\mathbf{\dfrac{1}{2}a + \dfrac{1}{2}y = 3 ---- (2)}[/tex]

[tex]\mathbf{a= \dfrac{3 - \dfrac{1}{2}(5)}{\dfrac{1}{2}} = 1}[/tex]

a = 1

Thus, the total number of horses he had at first were:

= 5 + 1 + 1

= 7 horses

Step-by-step explanation:

The profit made is equal to 2.25-2.25 which is 0.

The situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero. which is the correct answer would be an option (B).

Distance is defined as the product of speed and time.

As per option (A),

The overall change in temperature = 10 - (-10) = 20 degrees

As per option (B),

The profit made is equal to 2.25 - 2.25 = 0 which is zero.

As per option (C),

The overall change in altitude = 21 - 0 = 21 kilometers

As per option (D),

The total distance traveled by person = 3.1 + 3.1 = 6.2 miles

Thus, the situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero.

Hence, the correct answer would be option (B).

Answer:5 and 3

So we let the number take the letter b, anc the expression of the question is:

b^2+15=8×b.....so

b^2+15=8b

Then we take the 8b to the other side of the equal sign so that it becomes...

b^2+15-8b=0

Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...

From there we work out to get two different numbers...either b-5=0

b=5

Or b-3=0

b=3

So the two numbers are 5 and 3

Answer:

28:35

Step-by-step explanation:

Since Rita is trying to prove that the two triangles are similar, she will be looking for corresponding sets of sides that have an equivalent ratio. Therefore, since for the big triangle she uses sides PQ and PR, the corresponding sides on the smaller triangle would be PS and PT, which have a ratio of 28:35. Hope this helps!

The statement is completed by 28 :35, the correct option is B.

Two triangles of the same shape are said to be similar when their corresponding sides are proportional.

The triangle RPQ

The length of PS is equal to 28

The length of SQ is equal to 2x

The length of PT is equal to 35

The length of TR is equal to 60

The triangles  SPT and QPR are proved to be similar in Step 4 by the property that corresponding sides of similar triangles are in proportion.

(2x + 28):95 =28 :35

Therefore, the statement is completed by 28 :35, the correct option is B.

Answer:

x + 8 + 12 + 11 = 43

Step-by-step explanation:

The perimeter is the length of the 4 sections of fencing.

If x represents the fourth section and the perimeter is 43, then

x + 8 + 12 + 11 = 43, that is

x + 31 = 43 ( subtract 31 from both sides )

x = 12

The length of the fourth section is 12 ft

Answer:

45 , 135

Step-by-step explanation:

LET ONE ANGLE BE x AND OTHER ANGLE BE 45+2x

since they are supplementary angles ,

x+2x+45=180

3x = 180 -45

3x = 135

x = 135/3

x =45 degree

therefore measure of one angle = 45 degree and other angle angle  = 2*45+45 = 90+45 = 135 degree

Answer: 36 inches

Step-by-step explanation:

Since we know that the volume of the cylinder is 576π and that the radius is 4 inches, we can fill in the given numbers before solving the unknown.

V = π * 4^2 * h

π(pi) is the same as 3.14

4^2 is the same as 4 * 4 which is 16

Volume = 1,808.64 (576π)

First, we will be replacing the variables with the given numbers:

V = π * 4^2 * h --> 1,808.64 = 3.14 * 16 * h

To get the unknown, we first have to make sure it is by itself. To do that, we must divide 1,808.64 by 3.14 which is 576. Now we have 576 = 16 * h, to get to 'h', we must divide one more time, 576 divided by 16 is 36.

We are left with 36 = h. So the final answer is 36.

2.7 * 10 ^-5 / 9 * 10 ^-6

First divide the numbers

2.7 / 9 = .3

Then divide the exponents

10^-5 / 10 ^ -6

When we divide exponents we subtract

10^(-5 - -6) = 10 ^1

.3 * 10 ^1

But scientific notation has a number between 1 and less than 10

Move the decimal 1 place to the left, so we subtract 1 from the exponent

3 * 10 ^ (1-1)
