Answer:

14cm

Step-by-step explanation:

Volume of the pyramid = Base area × height/3

V = BH/3

Base area = 14×width

Height= 9cm

Volume = 168cm³

Substitute into the formula

168 = 4w×9/3

36w = 168×3

36w = 504

w = 14cm

Hence the width of the pyramid is 14cm

Answer:

x - 80

Step-by-step explanation:

"80 less than x"

__________________

We have the expression 80 less than x. X has no artifical value therefore we do nothing with it. Based off of the wording of the sentence, it says that the total of this unknown number is 80 less than x. Meaning the 80 has been subtracted by x to get this unknown number. Therefore,

x - 80

Answer:

90

Step-by-step explanation:

4(-5)² + (-5) + (-5)

4(25) - 10

100 - 10 = 90

Answer:

[tex]f(-5)=90[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=4x^2+x-5[/tex]

In order to find f(-5), substitute -5 for x:

[tex]f(-5)=4(-5)^2+(-5)-5[/tex]

Evaluate:

[tex]f(-5)=4(25)-10=100-10=90[/tex]

Therefore:

[tex]f(-5)=90[/tex]

Answer: 457.3

Step-by-step explanation:

[tex]V=\frac{lwh}{3}[/tex]

[tex]V=\frac{14*14*7}{3}[/tex]= 457.3

Answer:

V= 1568 in^3

Step-by-step explanation:

B = 14^2 = 196

896 = 14^2 + 2(14) (l)

896 = 196 + 28 (l)

700 = 281 l

25 = l

7^2 + b^2 = 25^2

49 = 625

24

1/3 (196)(24) = 1568

Step-by-step explanation:

step 1. x = .484848 . . . repeats

step 2. 100x = 48.48484848 . . . (multiply by 100)

step 3. subtract x from 100x : 99x = 48

step 4. x = 48/99 (now add the 2 back in)

step 5. answer: 2-48/99.

2.484848 as mixed number = [tex]2\frac{30303}{62500}[/tex]

A mixed number is a whole number, and a proper fraction represented together. It generally represents a number between any two whole numbers.

Given,

2.484848

Multiplying and Dividing with 1000000

(2.484848 ×1000000)/1000000

2484848/1000000

Since the greatest common factor of 2484848 and 1000000 is 16, we can simplify the fraction and show the same amount

2484848 ÷ 16/1000000 ÷ 16

= 155303/62500

As the numerator is greater than the denominator, we have an improper fraction, so we can also express 2.484848 as a mixed number

= [tex]2\frac{30303}{62500}[/tex]

Hence, [tex]2\frac{30303}{62500}[/tex] is the mixed number for 2.484848.

Answer:

0.80589

Step-by-step explanation:

So all of the numbers of correct answers less than 4 are 0,1,2,3

We need to calculate the probability for each separately and then add them together.

To find the probability we have to first find the combination. We know that there’s n=8 trials and that p=0.3. So 1-0.3 gives us 0.7.

The combination formula is: ! / (!(−)!)

So the n would always =8, and the r would be 0,1,2,3. So you would have to calculate it for 0,1,2,3 Separately. This can be done by hand or you can use a simple combinations calculator online.

For 0;

The combination is 1,

1 x 0.3^0 x 0.7^8-0 =

0.057648

For 1;

The combination is 8,

8 x 0.3^1 x 0.7^8-1 =

0.19765

For 2;

The combination is 28

28 x 0.3^2 x 0.7^8-2 =

0.296475

For 3;

The combination is 56

56 x 0.3^3 x 0.7^8-3 =

0.254122

All that’s left is to add these four numbers;

0.057647 + 0.19765 + 0.296475 + 0.254122 = 0.80589

Using the principle of binomial probability, the probability of correct answers fewer than 4 is : 0.8059

Recall the binomial probability formula :

P(x = x) = nCx * p^x * q^(n-x)

Where :

P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)

Answer:

-7/20

Step-by-step explanation:

1/4 - 3/5 = 5/20 - 12/20 = -7/20

Answer:

34 degrees

Step-by-step explanation:

Before solving for g, we must remember that the inside of a triangle will always equal 180 degrees. Also, keep in mind that the little square at the top left corner of the triangle represents 90 degrees, so we can add both the existing degrees we know of:

90 + 56 = 146

And to find g, we simply subtract 180 by 146:

180 - 146 = 34

So, g is 34 degrees

Answer:

two times a number (m) is increased by 7

Step-by-step explanation:

Answer/Step-by-step explanation:

A. "The slope is two": FALSE

Slope (m) = ∆y/∆x = -(2/1) = -2

The slope is -2 not 2

B. "The slope is negative": TRUE

The slope is -2 as solve above.

C. "A point on the line is (5, 0)": FALSE

If you check through the graph, there's no point on the graph where x = 5 and y = 0. However, what wwe have is (0, 5).

Answer: 1. 3/8-1/4=1/8

2. 3/8+1/4=5/8

3. x=5/8

Step-by-step explanation: 1. you have to subtract 3/8 by 1/4 because you have to use the largest number to subtract for the smallest number so 3/8-1/4=1/8

2. Add by adding 3/8 by 1/4 because you have to find the value of x so 3/8+1/4=5/8

3. look at number 2. and the answer is x= 5/8

Answer: The number is =5

Step-by-step explanation:

21  +                  3X                              =         ("Difference means subtract.)                           2X

Twenty-one more than three times a number is equal to the difference between 46 and twice the number

Then write the proper equation:     21+3x= 46-2x.

Next get rid of the smaller "x" so 3x+2x=46-25

solve X

Answer:

  f(x) = 2x^2 -12x +16

Step-by-step explanation:

The zeros tell you the factored form is ...

  f(x) = a(x -2)(x -4)

Then f(3) is ...

  f(3) = -2 = a(1)(-1) = -a

  a = 2

So the factored function is ...

  f(x) = 2(x -2)(x -4)

Expanded to standard form, we get ...

 f(x) = 2x^2 -12x +16
