Serena is making a model of one of the Egyptian pyramids. The square base has sides that are all 4.2 in. Each of the triangular faces has a base of 4.2 in and a height of 3.6 in. How much paper would it take to cover the entire pyramid?

Answer:

(8,3)

Step-by-step explanation:

Hello There!

This is the rule for reflection over y axis:

(x,y) -----> (-x,y)

So if the point (-8,3) we're to reflect over the y axis then the x value would stay the same but the sign would flip

So instead of -8 it would be +8

The y value does not change so the new coordinates would be

(8,3)

Answer:

Surface area = 24 in.²

Step-by-step explanation:

Surface area of the cube = 6a²

Where,

a = length of the each side of the cube = 2 in.

Plug in the value into the formula

Surface area of the cube = 6(2²)

= 6 × 4

Surface area = 24 in.²

I hope this helps you answer your question.

Answer:

11.7

Step-by-step explanation:

First HK can be found via Pythagorean Theorem

6^2 + 10^2 = 36 + 100 = 136

The square root of 136 is (rounded to the nearest tenth): 11.7

GJ is congruent to HK

GJ = 11.7

Answer:

a. 0.3

Step-by-step explanation:

The probability that a randomly selected car with no 4-wheel drive has third-row seats is 0.3 option (A) 0.3 is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Let's suppose A is the car with no 4-wheel drive

Let's suppose B is the car with third-row seats

As we know,

P(B|A) = n(A ∩ B)/n((A)

The probability that a randomly selected car with no 4-wheel drive has third-row seats:

From the table:

n(A ∩ B) = 12

n((A) = 40

P(B | A) = 12/40

P(B | A) = 0.3

Thus, the probability that a randomly selected car with no 4-wheel drive has third-row seats is 0.3 option (A) 0.3 is correct.

Answer:

He can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

Step-by-step explanation:

Given that Harry’s TV plan cost $ 49.99 per month plus $ 3.49 per first run movie, to determine how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of $ 100, the following calculation must be performed:

100 - 49.99 = 50.01

50.01 / 3.49 = X

14.32 = X

49.99 + (3.49 x 14) = 98.85

Thus, he can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

Answer:

r ≈ 2.5

Step-by-step explanation:

98 = 5(πr^2)

divide 5 by both sides

19.6 = πr^2

divide π by both sides

6.2388 = r^2

square root both sides

r = 2.49777

r ≈ 2.5

The number of stakes that you need to be required should be 400 stakes.

Since You want to put a stake every metre around the perimeter of a square plot that measures 100 metres on every side.

So here the square does have 4 sides

So,

= 100 (4)

= 400

hence, The number of stakes that you need to be required should be 400 stakes.

Let the angles be ABC (See attachment 2)

[tex]\angle CAB[/tex] is corresponding to 50 degrees. So:

[tex]\angle CAB=50[/tex]

[tex]\angle ABC[/tex] is corresponding to 55 degrees. So:

its a symmetrical open curve formed by the intersection of a circular cone with a plane at a smaller angle with its axis than the side of the cone.

Step-by-step explanation:

A hyperbola is an open curve with two branches, the intersection of a plane with both halves of a double cone. The plane does not have to be parallel to the axis of the cone; the hyperbola will be symmetrical in any case.

Answer:

B. AA

Step-by-step explanation:

The diagram given shows that two angles in ∆ABC are congruent to two corresponding angles in ∆STU.

Invariably, the third unknown angle of both triangles would also be equal going by the third angle theorem.

Thus, based on the AA Similarity Theorem which says that two triangles are similar to each other if two corresponding angles of one is congruent to two angles in the other, ∆ABC ~ ∆STU.

The probability of not selecting blue.

This means that any of the other colors is selected.

So, we have:

[tex]P(Not\ Blue) = P(Red) + P(Green)[/tex]

[tex]P(Not\ Blue) = \frac{Red}{Total} + \frac{Green}{Total}[/tex]

[tex]P(Not\ Blue) = \frac{6}{15} + \frac{4}{15}[/tex]

Take LCM
