Able is carving a rectangular pyramid clock out of green quartz. The length of the rectangle base is 14 cm and the height of the clock is 9cm. If the clock needs to have a volume of 168cm3 what is the width of the base

Answers

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

Assume that random guesses are made for eight multiple choice questions on an SAT test, so that there are n= 8 trials, each with probability of success (correct) given by p=0.3. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4​

Answers

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 :

n = number of trials x < 4 p = probability of success = 0.3q = 1 - p = 1 - 0.3 = 0.7

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

Using a binomial probability calculator :

P(x = 0) = 0.0576P(x = 1) = 0.19765P(x = 2) = 0.29648P(x = 3) = 0.25412

Therefore,

P(x < 4) = (0.0576+0.19765+0.2965+0.25412) = 0.8059

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

Answers

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

5x=25

x=5

How can I get equation x+4=-12 from equation x/4+1=-3

Answers

Answer:

All terms of the equation were divided by 4.

Step-by-step explanation:

When we are given a equation, it is possible to multiply or divided all of the terms of the equation by a factor.

In this question:

We are given:

[tex]x + 4 = -12[/tex]

And end up with:

[tex]\frac{x}{4} + 1 = -3[/tex]

Which means that all terms of the equation were divided by 4.


What is the asymptote for the function?
I tried to do it but I can’t

Answers

Answer:

Horizontal Asymptote → y = 17

Step-by-step explanation:

Given function is f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

Here, the parent function is g(x) = [tex]\frac{2}{5}(16)^x[/tex]

Parent function has a horizontal asymptote as y = 0

If the function g(x) is shifted 13 units left and 17 units up, new function will be f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

When the parent function is shifted 17 units up, horizontal asymptote shifts 17 units upwards.

Therefore, horizontal asymptote of the image function becomes y = 17.

Answer:

x= -6

y= -5

Step-by-step explanation:

(x,y) = (-6, -5)

Answer:

(-6,-5)

x=-6

y=-5

Step-by-step explanation:

9x-7y=-19

5x-3y=-15

When solving with elimination, you multiply both equations by a number to get two terms to cancel each other out.

We can try to get the y's to cancel out. The LCD of 7 and 3 is 21, so we multiply one equation by 3 and another by -7 (to get one -21y and one 21y)

{9x-7y=-19}*3=

27x-21y=-57

{5x-3y=-15}*(-7)=

-35x+21y=105

Now, we combine the two equations.

27x-21y=-57

-35x+21y=105

-8x=48

Now, solve for x.

-8x=48

x=-6

Now we can plug x into one of the original equations to get y.

I will use 9x-7y=-19.

9(-6)-7y=-19

-54-7y=-19

Add 54 to both sides.

-7y=35

y=-5

We can put these values into an ordered pair: (-6,-5).

Answers

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

1/3 (196)(24) = 1568

Find g in the right triangle.

Answers

hshshshshshshs /// G equals 34

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

Hope this helps :)
