Answer:

Assuming this is a rectangular prism, it should be:

(20x3.75) x2 + (20x15) x2 + (12.5x3.75)x2

Answer:

using elimination, the best first step is multiply the first equation by -3. multiply the second equation by 3 doesn't do anything to eliminate one of the unknowns. solving for x in the first equation or solving for y in the second equation are the substitution method, not the elimination method.

Answer: True

Step-by-step explanation:

Probability theory, is a mathematical branch that has to do with how random phenomena are analysed. To solve for probability, one has to divide the number of events aggregate by the amount of possible outcomes.

We should note that the statement in the question regarding probability theory providing mathematical rules that are assigned probabilities to the outcomes of the random experiments is said to be true.

Answer: (hope I got them correct)

A) -15/7

B) [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex]

C) It cuts the x-axis at (-4/15,0) and the y-axis at (0,-4/7).

Step-by-step explanation:

A) Slope = [8-(-7)]/(-4-3) = -15/7

B) Let [tex]y=-\frac{15}{7}x+c[/tex] be the required equation.

Substitute x=-4, y=8.

8=(-15/7)(-4)+c

c=-4/7

The equation is therefore [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex].

C) Substitute y=0, we will get x = -4/15 i.e. it cuts the x-axis at (-4/15,0).

Substitute x=0, we will get y = -4/7 i.e. it cuts the y-axis at (0,-4/7).

Step-by-step explanation:

Answer:
[tex](8x-5)^{2}[/tex]

Step-by-step explanation:

Rewrite 64[tex]x^{2}[/tex] as [tex](8x)^{2}[/tex]
[tex](8x)^{2}[/tex]−80x+25

Rewrite 25 as 5^2.

(8x)^2−80x+5^2

Check that the middle term is two times the product of the numbers being squared in the first term and third term.

80x=2⋅(8x)⋅5

Rewrite the polynomial. [tex](8x)^2[/tex]−2⋅(8x)⋅5+[tex]5^{2}[/tex]

Factor using the perfect square trinomial rule [tex]a^{2}[/tex] −2ab + [tex]b^{2}[/tex]= [tex](a-b)^{2}[/tex], where a=8x and b=5.
[tex](8x-5)^{2}[/tex]

Answer:

prove to be right should be the correct answer?

Step-by-step explanation:

In cases like that, switch the word out for it's definitions and choose the one that fits best too, like "He was not sure how he would prove his actions to be right to his family"

I think it is going to be number 4

Hey there!

The correct graph is A

The slope, 2, is a positive slope, which means that the graph will go left to right going up, which rules out graph B.

The y-intercept is 1, which means it will intercept the y-axis at point (0, 1). That rules out graph C.

This means that graph A is correct.

Hope it helps and have a great day!

Answer:

○ [tex]\displaystyle a[/tex]

Step-by-step explanation:

From the y-intercept of [tex]\displaystyle [0, 1],[/tex] you can either move two blocks south over one block west, or two blocks north over one block east. Either way, you are still using the rate of change [slope] correctly:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m[/tex]

I am joyous to assist you at any time.

Answer:

b.

Step-by-step explanation:

1. You have the following parent function given in the problem above:

f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)

2. If you take the parent function and make y=f(x+3), then you have:

(The function is shifted 3 units left on the x-axis).

3. Then you if you make y=f(x+3)-2, as following, you obtain:

(The function is shifted 2 units down on the y-axis).

4. Therefore, that is how you obtain the final function.

The answer is the graph shown in .b

Answer:

Kate did 15/8 part more than that of John.

Step-by-step explanation:

Given that,

John did 3 3/4 of his homework while Kate did 1 7/8 of her homework.

We need to find how much more of their  homework did Kate do than John. It can be calculated as follows :

3 3/4 = 15/4

and

1 7/8 = 15/8

So,

Difference,

[tex]d=\dfrac{15}{4}-\dfrac{15}{8}\\\\=\dfrac{15}{8}[/tex]

So, the required answer is 15/8.

The value of Cosα  from the triangle is 21/29

ABC is a right angled triangle

We have to find the Cosα

We know that cosine function is a ratio of adjacent side and hypotenuse

Let us find the value of  Cosα

The adjacent side of angle α is 21

The hypotenuse is 29 in the triangle

Cosα = Adjacent side/hypotenuse

Plug in the values of adjacent side and hypotenuse

Twenty one divided by twenty nine

=21/29

Hence, the value of Cosα  from the triangle is 21/29

Answer:

NRs. 8925

Step-by-step explanation:

176 dollars = 100 pounds

132 dollars = ??? pounds

Using cross-multiplication, we get:

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Now, 1 pound = NRs. 119

So 75 pounds = NRs. ???

Using cross-multiplication again, we get:

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925  

So the answer is 8925 Nepali rupees

The Nepali rupees can be exchanged with 132 dollar should be considered as the NRs. 8925

Since

176 dollars = 100 pounds

And, for 132 dollars = ??? pounds

So here we applied cross multiplication

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Also, 1 pound = NRs. 119

Now

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925
