Answer: 16.2

Step-by-step explanation:

8.6 + 2.2 = 10.8

10.8 x 1.2 = 16.2

Answer:

16.2

Step-by-step explanation:

Answer: (q°r)(4) = 30

(r°q)(4) = 36

Step-by-step explanation:

First, when we have two functions f(x) and g(x), we have that:

(g°f)(x) = g(f(x))

So we are actually evaluating one function with other function.

Now, solving the problem:

q(x) = 2x - 2

r(x) = x^2

we have:

(q°r)(x) = q(r(x)) = 2*r(x) - 2 = 2*(x^2) - 2

(r°q)(x) = r(q(x)) = q(x)^2 = (2*x - 2)^2

Then:

(q°r)(4) = q(r(4)) = 2*r(4) - 2 = 2*(4^2) - 2 = 2*16 - 2 = 32 - 2 = 30.

(r°q)(4) = r(q(4)) = q(4)^2 = (2*4 - 2)^2 = 6^2 = 36.

Answer:

Step-by-step explanation:

7/20

Represent the total budget amount by b.

Then from this b, subtract b/4 and then from the result subtract 2/5:

b - b/4 = (3/4)b; now from this (3/4)b subtract (2/5)b:

Converting these proper fractions to decimal fractions, we get:

0.75b - 0.40b = 0.35b

This tells us that 35/100, or 7/20, of Jaime's budget is for tutors.

Answer:

-18

Step-by-step explanation:

Step 1: Substitute your x and y values in

[tex]-(2)(-3)^{2} \\(-2)9\\-18[/tex]

Therefore the answer when x = 2 and y = 3 is -18

Answer:

It is not a function.

Step-by-step explanation:

If the x input or the y output in the given equation have no meaning or does not have any sense, then it will not form a function. We need to see if there are two of the x - intercept which are same. Then the graph will be a straight vertical line. Also the slope of the function cannot be determined.

Answer:

2/3

Step-by-step explanation:

Choose two points from the graph; count how far one point is away from the other. Simplify if needed.

[tex](2x-1)(x+5)=2x^2+9x-5=0[/tex].

The quadratic equation has a general form of

[tex]ax^2+bx+c=0[/tex].

So your "b" is 9.

Hope this helps.

Answer:  Answer is in the steps

Step-by-step explanation:

(2x-1)(x+5) = 0    First expand the left side by apply the distributive property twice.

(2x -1)(x+5) =0  

x(2x -1) =  2x^2 -1x  

5(2x -1) =  10x -5  

Now rewrite them all together

2x^2 - 1x +10x -5  = 0   combine like terms on the left side.

[tex]2x^{2}[/tex] + 9x -5 = 0      a is the first leading coefficient,b is the second leading coefficient, and  c is the constant.

So in this case, the value of b is 9.

Answer:

Total distance traveled= 21h miles

Step-by-step explanation:

You biked at 10 mph for h hours

Speed= 10 mpg

Time = h hours

Distance covered= speed*time

Distance covered= 10h miles

walked at 3mph for twice as long as I biked,

Speed= 3 mph

Time= twice as long as biked

Time= 2(h) hours

Distance= 2h*3

Distance= 6h miles

ran at 10mph for one quarter as long as I walked

Speed= 10 mph

Time= 1/4 of(2h)

Time= 1/2h hours

Distance= 1/2h*10

Distance= 5h miles

Total distance traveled

= 10h miles +6h miles+ 5h miles

Total distance traveled= 21h miles

Hope this helps ;) ❤❤❤

Answer:

B) 17/30

Step-by-step explanation:

The expression is given to you:

(2b + 4h)/(bh)

The measurements for the variables are also given to you:

b = 10 ft.

h = 12 ft.

Plug in the corresponding numbers to the corresponding variables:

(2(10) + 4(12))/(10 * 12)

Solve. Remember to follow PEMDAS. First, solve for the multiplications within the parenthesis:

((2 * 10) + (4 * 12))/(10 * 12)

((20) + (48))/(120)

Next, Add 20 with 48:

(20 + 48)/120 = (68)/120

Then, divide:

68/120 = 17/30

B) 17/30 is your answer.

1 liter of water equals 1000 milliliters.

To find who has more water, you need to convert (the unit) of each person to either liters or milliliters.

Since it asks for millimeters, I'm going to convert Tutu's 7/10 liters to milliliters. Since there are 1000 milliliters in every liter, you have to multiply 7/10 by 1000. 7/10 multiplied by 1000 is 700.

So Pete has 500 milliliters of water and Tutu has 700 milliliters of water.

Now you need to find the difference of 700 and 500 by subtracting.

700-500=200

Tutu bought 200 more milliliters of water than Pete.

Answer:

No, the triangles are similar with a scale factor of ⅔

Step-by-step explanation:

Given that ∆TUV was transformed to ∆WXY, it means the original lengths of ∆TUV were multiplied by a scale factor that reduced the lengths of ∆TUV to get the lengths of ∆WXY.

AA scale factor of ³/2 will increase the lengths rather than reduce it.

Therefore, the scale factor that was used was ⅔.

Thus, ⅔ of UT will give you the size of XW. Check it out below:

UT = 12, therefore, ⅔*12 = 8.

Answer:

Angle NKO and Angle OKL are adjacent and complementary

Step-by-step explanation:

Adjacent - yes - they have the common vertex K and the common side KO.

Vertical - no - vertical angles are created by two intersecting lines, and angles NKO and OKL are not.

Complementary - yes - since it's given to us that JL and MN are perpendicular, that means that they intersect at 90 degree angles. This means that angles NKO and OKL add up to 90 degrees, and because complementary angles are angles that add up to 90 degrees, NKO and OKL are complementary.

Supplementary - no - supplementary angles are angles that add up to 180 degrees, and since NKO and OKL add up to 90 degrees, they can't be supplementary.

Linear Pair - no - a linear pair is a pair of angles that are adjacent and supplementary. Angles NKO and OKL are adjacent, but since they're not supplementary they can't be a linear pair.

Answer:

(a) the critical value of t at P = 10% and 16 degrees of freedom is 1.337.

(b) the critical value of t at P = 10% and 11 degrees of freedom is 1.363.

(c) the critical value of t at P = 1% and 23 degrees of freedom is 2.500.

(d) the critical value of t at P = 10% and 22 degrees of freedom is 1.321.

(e) the critical value of t at P = 20% and 12 degrees of freedom is 0.8726.

(f) the critical value of t at P = 5% and 8 degrees of freedom is 1.860.

Step-by-step explanation:

We have to find the critical t value for each of the following confidence levels and sample sizes given below.

As we know that in the t table there are two columns. The horizontal column is represented by the symbol P which represents the level of significance and the vertical column is represented by the symbol '[tex]\nu[/tex]' which represents the degrees of freedom.

(a) So, here the level of significance = 1 - confidence level

                                                            = 1 - 0.90 = 0.10

And the degrees of freedom = n - 1

                                                = 17 - 1 = 16

Now, in the t table, the critical value of t at P = 10% and 16 degrees of freedom is 1.337.

(b) So, here the level of significance = 1 - confidence level

                                                            = 1 - 0.90 = 0.10

And the degrees of freedom = n - 1

                                                = 12 - 1 = 11

Now, in the t table, the critical value of t at P = 10% and 11 degrees of freedom is 1.363.

(c) So, here the level of significance = 1 - confidence level

                                                            = 1 - 0.99 = 0.01

And the degrees of freedom = n - 1

                                                = 24 - 1 = 23

Now, in the t table, the critical value of t at P = 1% and 23 degrees of freedom is 2.500.

(d) So, here the level of significance = 1 - confidence level

                                                            = 1 - 0.90 = 0.10

And the degrees of freedom = n - 1

                                                = 23 - 1 = 22

Now, in the t table, the critical value of t at P = 10% and 22 degrees of freedom is 1.321.

(e) So, here the level of significance = 1 - confidence level

                                                            = 1 - 0.80 = 0.20

And the degrees of freedom = n - 1

                                                = 13 - 1 = 12

Now, in the t table, the critical value of t at P = 20% and 12 degrees of freedom is 0.8726.

(f) So, here the level of significance = 1 - confidence level

                                                            = 1 - 0.95 = 0.05

And the degrees of freedom = n - 1

                                                = 9 - 1 = 8

Now, in the t table, the critical value of t at P = 5% and 8 degrees of freedom is 1.860.

Answer:x=-4+0.1/4

Step-by-step explanation:x+x+2+2x=-2.1-10-2

We move all terms to the left:

x+x+2+2x-(-2.1-10-2)=0

We add all the numbers together, and all the variables

x+x+2x+2-(-14.1)=0

We add all the numbers together, and all the variables

4x+16.1=0

We move all terms containing x to the left, all other terms to the right

4x=-16.1

x=-16.1/4

x=-4+0.1/4

Answer:

-1

Step-by-step explanation:

Answer is - 1

Answer:

-14 or 10.

Step-by-step explanation:

It is given that, on a number line, suppose point E coordinate of -2, and EG=12.

We need to find the possible coordinates of point G.

Since EG=12 it means point distance between point E and G is 12 units, therefore point G must be on 12 units left or write from point E.

If point G is 12 units left of E, then

G=-2-12=-14  

If point G is 12 units right of E, then

G=-2+12=10  

Therefore, the possible coordinates of point G are -14 or 10.

Answer:

[tex]\frac{17}{100}[/tex]

Step-by-step explanation:

A percentage is basically another way of writing a fraction.

If we have a percentage, x%, then it's fraction will be [tex]\frac{x}{100}[/tex].

Since 17 is the percentage here, the fraction is [tex]\frac{17}{100}[/tex].

This can't be simplified any further as 17 is a prime number.
