Find the midpoint of (4,-1) and (2, -7).

On photos i showed 2 ways of possible solutions

Answer: p=5

Step-by-step explanation:

6(3p-1)=84

You can now do it two ways. This is the first way:

Divide by 6 so the equation now writes:

3p-1= 14

Then add the one onto the other side.

3p=15

Then divide 15 by 3

P=5

The other way is to expand the brackets first.

18p-6=84

Then add the 6 onto the other side.

18p=90

Then divide 90 by 18.

P=5

This is a bit more complex so I recommend the first way. Hope you can now explain to your son. Have an amazing day!

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:

14800

Step-by-step explanation:

To find the area of a trapezoid you and the little base and the big base. then divide the answer by two. Then you multiply the answer you just got by the height.

Equation:

145+225=370

370/2=185

185*80=14800

Area of the park is 14800 square yards

A quadrilateral with at least one pair of parallel sides is called Trapezoid

Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Given,

Short base a = 145 yards

Long base b = 225 yards

Height h = 80 yards

Area of the park = [tex]\frac{a+b}{2}h[/tex]

Area of the park =[tex](\frac{145+225}{2})80[/tex] = 14800 square yards

Hence, the area of the park is 14800 square yards

Step-by-step explanation:

2 x 3 = 6

5 x 3 = 15

7 x 3 = 21

9 x 3 = 27

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: x8 i really don't know if it is correct tell me plz

Step-by-step explanation:

The expression (x²)⁴ without exponents can be written as x × x × x × x × x × x × x × x.

The given expression is (x²)⁴.

It is known that the power rule of exponents states that:

(xᵃ)ᵇ = xᵃᵇ

Here, a = 2 and b = 4.

So using the power rule,

(x²)⁴ = x²⁽⁴⁾

       = x⁸

Now, it is known that exponents are actually the multiplication of the number with the same number again and again.

Here x is multiplied by itself 8 times.

So the expression can be written as:

x × x × x × x × x × x × x × x.

15 presents

Step-by-step explanation:

42 cm / 14 presents = 3 cm / 1

3cm / 1 presents = 45 / 15

Answer:

15 presents

Step-by-step explanation:

Since we are using unit rate, we have to find out how many centimeters he uses for 1 present. Therefore 42÷14=3 So he uses 3 centimeters of paper for 1 present. Since he used 45 centimeters of paper we divide that by 3 to see how many presents is in 45 centimeters. When dividing the answer is 15. Therefore he wraps 15 presents

Step-by-step explanation:

Answer:

the area is 20 units

Step-by-step explanation:

if you plot the points then draw the rectangle then you count the amount on each side and multiply 4 times 5

Answer:

We know that, for a right triangle:

Cos(A) = (adjacent cathetus)/hipotenuse

sin(A) = (opposite cathetus)/Hipotenuse.

If we are in a right triangle inside the unit circle, we have that hypotenuse = 1.

Now, when you draw the unit circle, now from the center of the axis you must draw a straigth line (that forms an angle of 120° with the x-axis), and in the point where it cuts the unit circle we do 2 things.

from this point, you can draw a parallel line to the y-axis, the point where this line touches the x-axis is the value of the cosine.

Now you draw a line that is parallel to the x-axis (remember that the line must pass trough the point of before), the point where this line cuts the y-axis is the value of the sine

You should get:

sin(120°) = 0.87

cos(120°) = -0.5

Answer:

d

Step-by-step explanation:

because it gets bigger so they are not going to have the same measures or lenghts.

The statement that is not true about the dilation is (c) the segment AB is congruent to the segment A'B

When a shape is dilated, the orientation of the shapes is preserved but the side lengths of the shapes are not congruent

This means that the side lengths of triangle A'B'C are not congruent to triangle A'B'C

Hence, the statement that is not true about the dilation is (c) the segment AB is congruent to the segment A'B

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:

y= 3x +4

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx +c, where m is the gradient and c is the y-intercept.

To find the value of m, use the gradient formula below:

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

Gradient

[tex] = \frac{4 - ( - 8)}{0 - ( - 4)} \\ = \frac{4 + 8}{0 + 4} \\ = \frac{12}{4} \\ = 3[/tex]

Subst. m=3 into the equation.

y= 3x +c

To find the value of c, substitute a coordinate.

When x=0, y=4,

4= 3(0) +c

c=4

Thus, the equation of the line is y= 3x +4.
