Answer:

Angle AED = Angle CEB —> Opposite angles

So; Angle CEB = 95°

I hope I helped you^_^

∠AED and ∠CEB are opposite angles so they will be the same so ∠CEB will also 95°.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Two opposite angles become by the intersection of two lines will always same.

Since E is the intersection point so ∠AED and ∠CEB are opposite angles.

So,

∠AED = ∠CEB

∠CEB = 95°.

Hence "∠AED and ∠CEB are opposite angles so they will be the same so ∠CEB will also be 95°".

Step-by-step explanation:

Answer:

Recall that the height of the object, in meters, is a function of elapsed time, in seconds. Thus what [tex]f(8)=12[/tex] means is that the object is at a height of 8 meters when 12 seconds have passed since its launch.

Best interpretation of the given f(8) = 12 is 8 seconds after the object is launched it is at a height of 12meters.

" Interpretation is defined as the explanation of something in your own words or as per your understanding."

According to the question,

Given,

H = f(t)

H represents the height in meters of an object

t represents the time in seconds

Interpretation of the given situation,

f(8) = 12

time = 8seconds

height of the object = 12meters

Hence, interpretation of the given situation is  8 seconds after the object is launched it is at a height of 12meters.

4x=9+1

4x=10

x=10/4

x=5/2 or 2.5

Answer:

x = 5/2

Step-by-step explanation:

Answer:

The side lengths are:

15, 30, and 30

Step-by-step explanation:

Let x determine the length of the smallest side length then

the other one is said to be 15 in larger so it's x + 15

finally the third size is said to be twice as the smallest one so it's 2x

The perimeter is the sum of all three sides added up

x + 2x + x + 15 = 75 add like terms

4x + 15 = 75 subtract 15 from both sides

4x = 60 divide both sides by 4

x = 15

Answer: D

Step-by-step explanation:

m = - 7/4

Point (4, -2)

y - - 2= -7/4(x-4)

y + 2 = - 7/4x + 7

y = - 7/4x +7-2

y = - 7/4 x + 5

The equation of the line that is parallel to the given line is option (D) [tex]y=-\frac{7}{4}x+5[/tex] is the correct answer.

The equation of a line means an equation in x and y whose solution set is a line in the (x,y) plane. The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term.

For the given situation,

The line is [tex]y=-\frac{7}{4} x-2[/tex] ------ (1)

The general equation of line in slope intercept form is

[tex]y = mx + c[/tex] ------ (2)

On comparing the equation 1 and 2, we get the slope as

⇒ [tex]m=-\frac{7}{4}[/tex] and

When two lines are parallel, then the slope of the parallel line is equal to the slope of the given line.

So, the slope of the parallel line is [tex]m = -\frac{7}{4}[/tex]

Thus the equation of the parallel line passing through the point (x1,y1) is (4,-2) as,

⇒ [tex]y-y1=m(x-x1)[/tex]

⇒ [tex]y-(-2)=-\frac{7}{4} (x-4)[/tex]

⇒ [tex]y+2=-\frac{7}{4} (x-4)[/tex]

⇒ [tex]y=-\frac{7}{4}x+\frac{7}{4} (4)-2[/tex]

⇒ [tex]y=-\frac{7}{4}x+7-2[/tex]

⇒ [tex]y=-\frac{7}{4}x+5[/tex]

Hence we can conclude that the equation of the line that is parallel to the given line is option (D) [tex]y=-\frac{7}{4}x+5[/tex] is the correct answer.

Answer:

  (0, -3)

Step-by-step explanation:

The y-intercept is the point where the graph crosses the (vertical) y-axis. That point is halfway between grid lines marked -2 and -4, so is at the grid line with the value -3. The x-coordinate there is 0, so the y-intercept point is ...

  (x, y) = (0, -3)

Since the y-intercept always has an x-coordinate of 0, we sometimes refer to the y-intercept using only the y-value: -3.

Answer:

(-11 , -16)

Step-by-step explanation:

The midpoint will always be, as the term suggests, in the middle of the line segment. You simply need to find the distance for both x & y, and to apply that to the midpoint. In this case:

Endpoint (x₁ , y₁): (5 , 10)

Midpoint (x₂ , y₂): (-3 , -3)

Note that when finding distance, you will subtract the point₂ from point₁:

x: 5 - (-3) = 8

y: 10 - (-3) = 13

Therefore, each time you plot another point, you will be subtracting 8 from the x value, and 13 from the y value:

Endpoint (x₃ , y₃) = Midpoint (-3 , -3) + (_ - 8 , _ - 13) = (-11 , -16)

(-11 , -16) is your answer.

Using midpoint formula

Answer:

31

Step-by-step explanation:

You divide, 372 divided by 12

the actual number of vans needed is 31 vans to accommodate the entire camp. To estimate the number of vans needed to accommodate the entire camp, we can use the concept of rounding up to the nearest whole number.

The number of vans required will be the total number of campers divided by the capacity of each van (12 passengers), rounded up to the nearest whole number.

Estimate:

Number of vans needed =[tex]\(\frac{372}{12}\)[/tex](rounded up to the nearest whole number)

[tex]\(\frac{372}{12} \approx 31\)[/tex]

So, the estimate suggests that around 31 vans will be needed to accommodate the entire camp.

To calculate the actual number of vans needed, we can use the exact division without rounding up.

Actual number:

Number of vans needed = [tex]\(\frac{372}{12} = 31\)[/tex] vans

Thus, the actual number of vans needed is 31 vans to accommodate the entire camp.
