What is the volume of this square pyramid?

Answer:

B

Step-by-step explanation

f(x)=x2-4x-5

Becomes

f(x)=x2-5x+x-5

Take out the common factor

f(x)=(x-5)(x+1)

Equate the given function equal to 0

0=(x-5)(x+1)

And then

x-5=0 -- x=5

x+1 = 0 == x=-1

Answer:

B

Step-by-step explanation:

we are given a quadratic function

we want to figure out the form which we don't need change

so according to the question

[tex] \displaystyle{x}^{2} - 4x - 5 = 0[/tex]

rewrite -4x as x-5x:

[tex] \displaystyle{x}^{2} + x - 5x- 5 = 0[/tex]

factor out x:

[tex] \displaystyle \: x({x}^{} + 1)- 5x- 5 = 0[/tex]

factor out -5:

[tex] \displaystyle \: x({x}^{} + 1)- 5(x + 1 )= 0[/tex]

group:

[tex] \displaystyle \: (x + 1 )(x - 5)= 0[/tex]

hence our answer is B

Answer:

cereal bowl- 2 cups

baby food jar- 4 fluid ounces

soda can- 12 fluid ounces

swimming pool- 1000 gallons

large can of paint- 1 gallon

Answer:

100 minutes

Step-by-step explanation:

Given data

Total distaance= 400meters

Speed= 4m/s

We know that the expression for speed is

Speed= distance/time

substitute to find time

4= 400/time

time= 400/4

time= 100 minutes

Answer:

The answer is B. 283.8 miles.[tex]\sqrt{b^2[/tex]

Step-by-step explanation:

Using the cosine rule:

b^2 = a^2 + p^2 - 2ap(cosB)

b^2 = 172.20^2 + 111.64^2 - 2 x 172.20 x 111.64(cos177.29)

b^2 = 42,116.33 - 38,448.82(cos177.29)

b^2 = 42,116.33 - (-38,405.82)

b^2 = 42,116.33 +38,405.82

b^2 = 80,522.15

[tex]\sqrt{b^2[/tex] = [tex]\sqrt{80,522.15}[/tex]

b = 283.76 miles = 283.8 miles

Answer:

D

Step-by-step explanation:

D says four-tenths and 2 times 2 is 4 and 5 times 2 is 10 so 2/5 is equal to 4/10.

Answer:

I am not sure on this one, sorry :(

Step-by-step explanation:

Answer:

I think x=0, and y=4

Step-by-step explanation:

P.S. I'm sorry if I'm wrong!

The rest of the side where the 8 is would 20 (28-8)

Set up proportions:

8/10 = 20/3x-5

Cross multiply

200 = 24x-40

Add 40 to both sides

240 = 24x

Divide both sides by 24

X = 10

Solve for the equation: 3x-5 = 3(10)-5 = 30-5 = 25

Answer:84

Step-by-step explanation:

-8+92

Lo puedes dar la vuelta

92-8= 84

Answer:

84

Step-by-step explanation:

So -8 + 92 = 92 - 8

   92

-     8

______

   84

So, -8 + 92 = 84

Answer:

The truck drove 213 miles.

Step-by-step explanation:

181.87-19.99= 161.88

161.88÷0.76= 213

Answer:

5

Step-by-step explanation:

8 times 15 equals 120, so if the volume is 600, 600/120 or 600/ 8 times 15 is equal to 5

Answer:

No; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. ANSWER: No; 9. ... No; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Answer:

Yes. An Equilateral Triangle have same angles and sides.

All sides are equal.

Answer:

500m

Step-by-step explanation:

a rectangle has 4 sides, so 30=60 and 20=40

60x5=300

40x5=200

300+200=500

500m

reason of 500

The main reason for this is he ran AROUND the rectangle and did it 5 TIMES, doing it once would be 100m.

Answer:

Step-by-step explanation:

Answer:

200π cm^2

Step-by-step explanation:

Sb = 8^2 π = 64π cm^2

a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm

Sl = 8x17xπ = 136 π cm^2

SA = 136π + 64π =200π cm^2

Answer:

Outlier: Value that is extremely to the right or the left due to an external cause

For math: 1 is the outlier

Answer:

I am not 100% but I believe they are 1 and 6 if there are 2 answer options

Step-by-step explanation:

The area of the base is 1/2 x s x s = 1/2 x 12 x 12 = 72 square cm

Volume = area of base x height/3

Volume = 72 x 14/3 = 336 cm^3

Answer:

0.1 is the outlier

Step-by-step explanation:

Though the question has a missing attachment (of the line plot), the question can still be answered.

The given data can be represented as;

[tex]\begin{array}{cc}{} &{Dots} & {0.1} & {1} & {0.5} & {2} & {0.6} & {4} & {0.7} & {1} \ \end{array}[/tex]

Notice that 0.1 is not as close as to other data as the closeness of 0.5, 0.6 and 0.7.

This implies that 0.1 is an outlier.

Answer:

0.1 is the outlier

Step-by-step explanation:

Look at the data on the line plot.

A line plot shows a number line 0.1 to 0.7 in intervals of 0.1. 0.1 has 1 dot. 0.5 has 2 dots. 0.6 has 4 dots. 0.7 has 1 dot.

The answer is "[tex]\frac{2}{3}[/tex]"

Step-by-step explanation:

In this question the graph file is missing which is defined in the attachment section please find it.

Let the 18 square boxes are available, 12 of those are in color.

If published in part, it will be

[tex]\to \frac{12}{18}= \frac{4}{6}=\frac{2}{3}[/tex]

There are two colors out of 3 square boxes.
