Answer: 3

Step-by-step explanation:

f(x)= -x + 4

Therefore f(-1)= -(-1)+4= 1+4= 5

h(x)= (3/2)x - 1

Therefore h(2)= (3/2)(2) -1= 3-1= 2

f(-1) - h(2)= 5 - 2= 3

Answer:

Volume = 125 mm^3

Step-by-step explanation:

Here, we want to get the volume of the cube

What we have to do here is to substitute the value of the area

We have this as

:

V = 25^(3/2)

V = (√25)^3

V = 5 * 5 * 5 = 125 mm^3

Answer:

y=Q+3D

Step-by-step explanation:

the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.

The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.

Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,

0.10x + 0.25y = 3.10      ...1

x = y + 3                        ...2

From equations 1 and 2, then we have

0.10(y + 3) + 0.25y = 3.10

0.10y + 0.30 + 0.25y = 3.10

0.35y = 2.8

y = 8

Then the value of 'x' is given as,

x = 8 + 3

x = 11

The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.

Step-by-step explanation:

Answer: Ben completes 3/10 of his book report  per hour

Step-by-step explanation:

Ben completes 1/4 of his book report in 5/6 of an hour

5/6 of an hour =  5/ 6 x 60 = 50 minutes

Therefore in 1 hour, which is = 60 minutes  he  completes

(1/4 x 60 minutes)/ 50 minutes

= 15/ 50

= 3/10 of his book report.

Answer:

  (a)  A'(-2, 1), B'(-4, -3), C'(-7, 0)

Step-by-step explanation:

If X is the center of rotation, the coordinates of point P are transformed like this:

  P' = -(P -X) +X

  P' = 2X -P

  (x, y) ⇒ (2(-5) -x, 2(3) -y)

  (x, y) ⇒ (-10-x, 6-y)

__

Your points are transformed to ...

  A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)

  B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)

  C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)

These coordinates match the first choice.

Answer:

cos theta=-1/2

theta=cos-¹(-1/2)=120

tan theta=tan 120=-√3

sin theta=sin120=√3/2

cos(- theta)=cos theta=cos 120=-1/2

Answer:

$1,065

Step-by-step explanation:

Simple interest equation: A=P(1+rt)

P (principal amount) = 750, r (rate) = 3.5%, t (time) = 12 years

A=750(1+(3.5)(12))

A=1065

The amount of an investment to be worth after 12 years should be considered as the $1,065

Since

The deposited amount is $750

The rate of interest is 3.5% per year.

And, the time period is 12

So,

A=750(1+(3.5)(12))

A=1065

Hence, The amount of an investment to be worth after 12 years should be considered as the $1,065

Answer:

the perimeter is 960

Step-by-step explanation:

The computation of the perimeter is shown below;

If we assume

= (24 × 2) + (6 × 2)

= 48 + 12

= 60

And, the area is 16 times to that of original So

= 60 × 16

Hence, the perimeter is 960

Answer:

M = (4,7)

Step-by-step explanation:

If points are (x₁,y₁) and (x₂,y₂), then the midpoints are given by :

[tex]M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

We have,

x₁ = -2, y₁ = 8, x₂ = 10 and y₂ = 6

So,

[tex]M=(\dfrac{-2+10}{2},\dfrac{8+6}{2})\\\\=(\dfrac{8}{2},\dfrac{14}{2})\\\\=(4,7)[/tex]

So, the midpoints of the given points are (4,7).

Answer:

Sum of their present ages  = 20 years

Step-by-step explanation:

Present age :

   Neha's age = x years

Reemas' age = x - 4

After 5 years:

       Neha's age = (x +5) years

       Reemas' age = (x - 4 + 5 ) = x + 1

Sum of the ages of Reema and Neha will be 30

Therefore,    

x + 5  + x + 1 = 30

x + x + 5 + 1 = 30

   2x +  6    = 30

            2x = 30 - 6

           2x = 24

             x = 24/2

            x = 12

Neha's age = 12 years

Reema's age = 12 - 4 = 8 years

Sum of their present ages = 12 + 8 = 20 years
