The height of the pyramid must be sliced by a factor of 7/8

From the question, we have the following parameters that can be used in our computation:

The base length of the pyramid is

L^2 = 64

L = 8

For the cross-section, we have

l^2 = 49

l = 7

Using the similar shapes, we have the height h to be

(L - l)/h = l/L

So, we have

(8 - 7)/h = 8/7

This gives

1/h = 8/7

Evaluate

h = 7/8

This means that the height of the pyramid must be sliced by a factor of 7/8

Answer:

x < 4

Graph: open dot on 4 and arrow pointing left.

Step-by-step explanation:

x + 5 < 9

Subtract 5 from both sides.

x < 4

You solved the inequality correctly.

To graph it, place an open dot on 4 and an arrow going left.

Answer:

The answer is an open circle to the left

Step-by-step explanation:

Closed circle means atleast and open means more or less than. THe equation is that 4 is more than a number. So that means it will go to the left and the circle would be open because it doesn't say at least, it's just <.

Answer:

3(16x+9)/4

make sure it's a fraction

Answer:

27 11/4x

Step-by-step explanation:

First we add the similar parts of the expression.

Whole numbers

6 + 9 + 5 + 7 = 27

Then we add the fractions that dont have x.

We only add the numerators (2 and 3) and dont change the denominators (4)

2/4 + 3/4 = 5/4

Now we add the ones with x.

5/4 + 3/4x + 3/4x = 11/4x

Now we combine those parts together, making

27 11/4x

Part A ending answer: 3 cups.

1/4 of a gallon=4 cups

If I understand this correctly, there was a total of 7 cups before it was poured, adding the original answer to this one.

7 cups would equal .43 gallons, a bit less than half a gallon. If that's so, then .43 would equal 43 percent, and 43% of 128 fluid ounces would be 55.04 fluid ounces. Now the further solution, with more numbers past the decimal, it would be equal to approximately 56.

Therefore, my answer, if I understood correctly, would be 56.

Answer: The probability of not choosing a black shirt is 8/10 or 80%.

Step-by-step explanation: You add up the number of total shirts and then subtract the number of black shirts.

Answer:

20% probability of not choosing the black shirt

Step-by-step explanation:

There are 10 shirts on the shelves. Each has a 10% chance of not being chosen. There are 2 black shirts which have 10% chance each of not being chosen. if you sum it up ( 10% ×2) you will get a 20% probability of the black not being chosen.

Therefore there is a 20% probability of not choosing the black shirt

Answer:

Perimeter = 14

Step-by-step explanation:

- Calculating the distance AB between (2,-6) and (5,-6)

AB = Square Root((x2 - x1)2 + (y2 - y1)2)

AB = Square Root((5 - 2)2 + (-6 - -6)2)

AB = Square Root((32 + 02))

AB = √(9 + 0)

AB = √9

AB = 3

- Calculating the distance BC between (5,-6) and (5,-2)

BC = Square Root((x2 - x1)2 + (y2 - y1)2)

BC = Square Root((5 - 5)2 + (-2 - -6)2)

BC = Square Root((02 + 42))

BC = √(0 + 16)

BC = √16

BC = 4

- Calculating the distance CD between (5,-2) and (2,-2)

CD = Square Root((x2 - x1)2 + (y2 - y1)2)

CD = Square Root((2 - 5)2 + (-2 - -2)2)

CD = Square Root((-32 + 02))

CD = √(9 + 0)

CD = √9

CD = 3

- Calculating the distance AD between (2,-6) and (2,-2)

AD = Square Root((x2 - x1)2 + (y2 - y1)2)

AD = Square Root((2 - 2)2 + (-2 - -6)2)

AD = Square Root((02 + 42))

AD = √(0 + 16)

AD = √16

AD = 4

- Perimeter

Perimeter of ABCD = AB + BC + CD + AD

Perimeter of ABCD = 3 + 4 + 3 + 4

Perimeter of ABCD = 14

Answer:

I have to say equally likely to happen or not to happen.

If this isn't the answer, maybe unlikely.

I hope this helps!!

Answer:

Unlikely.

Step-by-step explanation:

Although the sun rising tomorrow would be a certain thing, the given probability would change that. The probability is 1 which makes it unlikely, not impossible as there is still a chance.

Answer:

D- 3cm

Step-by-step explanation:

I looked it up

Hello there!

First things first, place the 2 on the y-axis. 2 is your "y" intercept.

Rule of thumb:  if there is a constant(single number) alone and without any variable next to it, it's going to be your y-intercept.

Next we need to count up three units from the y-intercept and over four units.

Overall:

The 2 should be plotted on the y-axis.

The new coordinate should be (5,4)

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

Step-by-step explanation:

Since there are 4 colours on the spinner and you need to spin it 3 times, spinning a red would be a 1 in 4 chance, then spinning a white would also be a 1 in 4 chance then spinning a blue would yet again be another 1 in 4 chance, so multiply them like so:

[tex]\frac{4*4*4}{1*1*1}[/tex]

Then, you'll get 1/64 in spinning those colours

if I calculated this right, it should be 175 :)

Answer:

7x + 96 = 180

Step-by-step explanation:

We are given that the right side of the equation should be 180 because that is equal to the sum of the triangle's interior angle measures.

We can solve for the left side by adding the triangle's interior angle measures.

(2x + 1) + (5x + 5) + 90

Remember that a right angle is 90°.

All we need to do from here is combine like terms:

= (2x + 5x) + (1 + 5 + 90)

= 7x + 96

So, the equation that represents the model is:

7x + 96 = 180

Answer:

C) 7x + 96° = 180

Step-by-step explanation:

their is one right angle and 2 equations. The sum of the interior angle is 180

90° + 2x + 1 + 5x + 5 = 180

Combine like terms

90 + 1 + 5 = 96

2x + 5x = 7x

7x + 96° = 180

Answer:

9m-8

Step-by-step explanation:

you need to group like terms and solve

Answer:

9m - 8

Step-by-step explanation:

We know that,

( - ) × ( - ) = ( + )

( + ) × ( + ) = ( + )

( - ) × ( + ) = ( - )

Accordingly, let us solve it now.

10m + ( – 8 ) + 9m +  ( – 10m )

Solve the brackets.

10m - 8 + 9m - 10m

Combine like terms.

9m - 8

Answer:

answer is 3/5

Step-by-step explanation:

Answer: y = -1/4x - 6

Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.

Answer:

-1/4x + -6

Step-by-step explanation:

The slope is -1/4 because slope = [tex]\frac{rise}{run}[/tex],

So:

-[tex]\frac{1}{4}[/tex] is the slope, also is negative.

The y intercept is -6 because it passes through -6 at the y axis.

Answer:

J' (-2, 2.5), K' (1, 2.5) L' (1, -2.75)

Step-by-step explanation:

With a scale factor of 1/2=.5 you can simply multiply all coordinates by .5 (or divide by 2)

J (-4,5) x 1/2= (-2, 2.5)

K (2,5) x . 5 = (1, 2.5)

L (2, -5.5) /2= (1, 2.75)

Answer:

According to Wolfram, "sided polygon in which the sides are all the same length and are symmetrically placed about a common center."

According to TheSchoolRun, "A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A polygon. A shape with curved sides is not a polygon."

So, yes, that is indeed a polygon.

Answer:

Audrey's shape is not a regular polygon.

Step-by-step explanation:

We know what a polygon is, but there are two types. Regular and irregular. A regular polygon's sides are all equal. An irregular polygon's sides are not all equal.

In this case, Audrey's shape is an irregular polygon. 3 of the lines are of unequal length to the rest which makes it irregular.
