Answer:

x=-3

Step-by-step explanation:

Hi there!

1) Determine the slope

Parallel lines always have the same slope. However, the given line x=8 is a vertical line organized in the form x=d, where d is the x-intercept. Therefore, the slope is undefined, and our line will also have an undefined slope.

Now, because this line will also be a vertical line, it will also be organized like:

x=d

2) Determine the x-intercept (d)

Note that all the points a vertical line passes through will have the same x-coordinate. We're given that this line passes through the point (-3,-2), so therefore, the x-intercept will be (-3,0).

Plug this into x=d:

x=-3

I hope this helps!

The complementary angle is

63°.

Step-by-step explanation:

This is very right trust mne

Mark me brainlist

The measure of the supplementary angle and the measure of a complementary angle as follows; The supplementary angle is 153°. The complementary angle is 63°.

Two angles whose sum is 90° are called complementary angles.

Two angles whose sum is 180° are called supplementary angles.

If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.

Those two-two angles are two pairs of supplementary angles.

That means, if supplementary angles are aligned adjacent to each other,

their exterior sides will make a straight line.

Therefore, The supplementary angle is 153°.

The complementary angle is 63°.

Step-by-step explanation:

Answer:

Solid A

Step-by-step explanation:

The formula to find the surface area of a cube = 6a²

Where a = side length

Solid A = 17ft

For solid A, surface area = 6 × (17 ft)²

= 1734 ft²

For Solid B

the conversion factor 3.28ft/ 1 m

Solid B = 5m

Hence, converting 5m to ft

1m = 3.28 ft

5m =

Cross Mulitiply

= 5m × 3.28ft

= 16.4 ft

Hence, the surface area of solid B =

6 × (16.4 ft)²

= 1613.76 ft²

The cube that has the larger surface area is Solid A

Step-by-step explanation:

a) The slope formula is given by

m = (y2 - y1)/(x2 - x1)

Let P1(7, 5) and P2(21, 15)

m = (15 - 5)/(21 -7)

= 10/14

= 5/7

b) Let's see if the slope is only a third of the one found in part (a) or m = 5/21. Let P1(0, 0) and P2(21, 5).

m = (5 -0)/(21 - 0)

= 5/21

Indeed, the slope is only a third of part (a), as we predicted.

Answer:

152.60 square units

Step-by-step explanation:

Area of the sector is expressed as;

A = theta/360 * Area of the circle

A =54/360 * 3.14*18²

A = 54/360 * 1,017.36

A = 54,937.44/360

A = 152.604

Hence the area of the sector to the nearest hundredth is 152.60 square units

[tex]50\:\text{kg water}[/tex]

Step-by-step explanation:

This question implies the constant rate or proportion of water to mass. Therefore, we can set up the following equation:

[tex]\frac{60}{90}=\frac{x}{75},\\\\x=\frac{75\cdot 60}{90}=\boxed{50\:\text{kg water}}[/tex]

Answer:

50 kg

Step-by-step explanation:

90 kg = 60kg

/90         /90

1 kg = 0.667kg

1 kg  = 0.667kg

* 75kg    * 75kg

75kg = 50 kg

Step-by-step explanation:

Area of the triangle (A') = 1/2bh

A' = 1/2bh............ Equation 1

Where b = base of the triangle, h = height of the triangle

From the diagram,

Given: b = 12.5 unit, h = 4 unit

Substitute into equation 1

A' = 1/2(12.5)(4)

A' = 25 squared unit.

Also,

Area of the rectangle (A) = Lenght(L)×width(w)

A = Lw............ Equation 2

From the question,

If the area of the rectangle is 40% larger than the area of the triangle

Therefore,

A = 1.4A'

A = 1.4(25)

A = 35 squared unit.

Also given: w = 3[tex]\frac{1}{2}[/tex] = 7/2

Substitute into equation 2

35 = L×7/2

7L = 35×2

7L = 70

L = 70/7

L = 10 units

Answer:

[tex]\frac{2}{13}[/tex]

Step-by-step explanation:

Since there are 26 students in the class and 6 play basketball, 15 play baseball, and 9 play neither, we need to find the intersection ([tex]\cap[/tex]) of the students who play basketball and the students who play baseball to find the number of students who play both.

Since it would appear that we would have 30 students total if we added up the ones who play basketball, baseball or neither, the intersection will be the difference between this total and the actual number of students in the class (26).

Therefore, the number of students who play both sports is [tex]6+15+9-26=4\:\text{students}[/tex]

Since there are 26 students in the class, the probability of randomly choosing one that plays both sports is:

[tex]\frac{4}{26}=\boxed{\frac{2}{13}}[/tex]

Responder:

Comprimento de cada parte = 40 cm

Explicação passo a passo:

Dados os comprimentos:

240 cm e 280 cm

Obtenha o maior fator comum de ambos os comprimentos, pois isso dará o comprimento máximo de cada um após ser dividido:

2 _240 _ 280

2 _ 120 _ 140

2 _ 60 _ 70

5 _ 30 _35

___ 6 __7

Portanto, o maior fator comum é:

(2 * 2 * 2 * 5) = 40

Isso servirá como o comprimento de cada parte após a divisão
