Answer:

Step-by-step explanation:

We need to multiply 0.98 by 2 which is 1.96 now we need to divide 0.98 by two which is 0.49, so add those together and you have 2.45. Hope this helps :)

Answer:

4.5 hours

Step-by-step explanation:

to find the average/middle (how long it would take them when working together) you add both numbers and divide by two

4+5=9

9÷2= 4.5

The time take by them to the job together is 5 hours.

Time Taken = 1 / Rate of Work If a piece of work is done in x number of days, then the work done in one day = 1/x Total Wok Done = Number of Days × Efficiency.

Efficiency and Time are inversely proportional to each other.

Given that, Sheila can frame in a room in 5 hours. David can do the same job in 4 hours.

We need to find the time taken by them if they work together,

So, the total hours taken by Sheila = 5 hours

So, she will do the work in 1 hour = 1/5 parts

Similarly, for David also, he will do in 1 hour = 1/4

Now, when they are working together in hour = 1/4 + 1/5

= 4+5 / 45 = 9/45 = 1/5

Since, there work in 1 hour = 1/5 units

That mean, they will do the whole work in 5 hours.

Hence, the time take by them to the job together is 5 hours.

Answer:

B. -1

Step-by-step explanation:

-1

According to the slope formula:

Slope = (y2 - y1)/(x2 - x1)

y2 = 6.1

y1 = 3.1

x2 = -5.5

x1 = -2.5

Therefore:

6.1-3.1/-5.5--2.5

Since negative negative is positive you are left with:

3/-3

Therefore the answer is -1.

Answer:

its independent and changes by constant factor per year

In the ranger's function, time is the independent variable, and the total number of deer in the park is the dependent variable.

Given data:

A park ranger recorded the number of deer living in a state park for several years and developed the function p ( t ) = 80 ( 1.2 )^t to model the total number of deer in the park "t" years after she began recording the data.

The total number of deer in the park is represented by "p(t)," which is the output of the function. As the value of "t" increases, the function calculates the total number of deer in the park based on the initial value of 80 and the growth rate of 1.2.

Hence, the time is the independent variable and number of deer is the dependent variable.

2787.6 (rounded to nearest tenth)

Step-by-step explanation:

The formula for the volume of a hemisphere is [tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] × r³ where r is the radius of the hemisphere. You can apply the formula to answer the question.

Volume =  [tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] × 11³

             = 887[tex]\frac{1}{3}[/tex][tex]\pi[/tex]

             = 2787.6 (rounded to nearest tenth)

Answer:

  1.1 ∠LKR = 90°

  1.2 ∠R = 32°

  1.3 ∠N = 32°

Step-by-step explanation:

1.1 An inscribed angle is half the measure of the arc it subtends. Angle LKR is half the measure of the arc of semicircle LNR, so is 90°.

  ∠LKR = 90°

__

1.2 ΔLKR is a right triangle with angles L1 = 58°, ∠K = 90°, so ∠R is ...

  ∠R = 90° -58°

  ∠R = 32°

__

1.3 ∠N subtends the same arc LK that ∠R does, so it has the same measure.

  ∠R = ∠N = 32°

Let the missing variable be x then yiu will get the answer above

Answer:

3

Step-by-step explanation:

5 - 4x = -7

add 4x to each side of the equation:

5 = 4x - 7

add 7 to each side:

12 = 4x

divide both sides by 4:

x = 3

proof:

5 = 4(3) - 7

5 = 12 - 7

Answer:

Step-by-step explanation:

    - 50 + (5 / 13)p         this says negative 50 plus 5/13 times p

if p = -26                      what does this epression evaluate to?

- 50 + (5 / 13) × p      p = -26      substitute the value of p into the expression

- 50 + (5 / 13) × (-26)      

- 50 + (5 (-26) / 13)                 I just rewrote the expression to make it clearer

                                               that the -26 in -26/1 and the  5 in 5 / 13    are

                                              both in the numerator over denominator 13

 - 50 + (5 (-26) / 13)              -26 / 13  evaluates to -2

 -50  + (5)(-2)    

 -50  + (-10)

 -50 - 10

 -60                

Answer:

j = $15

t = $5

Step-by-step explanation:

This question can be solved using simultaneous equation

let the price of t-shirt be represented with t

let the price of jeans be represented with j

From the question, these two equations can be derived

2j + 6t = 60  eqn 1

4j + 3t = 75  eqn 2

multiply eqn 1 by 2

4j + 12t = 120  eqn 3

Subtract eqn 2 from 3

9t = 45

divide both sides by 5

t = 5

Substitute for t in eqn 1

2j + 6(5) = 60

2j = 30

j = 15

Step-by-step explanation:

if x-4 is a factor of 2x^3 + x^2- 26x - 40

then f(4) = 0

f(x) = 2x^3 + x^2- 26x - 40

f(4) = 2(4)^3 + (4)^2 - 26(4) - 40

f(4)= 2(64) + 16 - 104 - 40

f(4) = 128 + 16 - 104 - 40

f(4) = 0

Answer: 3

Step-by-step explanation:

X,Y,Z

I can't see pictures, so I'll do my best.

y= always stays the same.

To find the slope, or x, you have to start at the y-intercept, and find the number of units up, then right.

For example, y=4/3+6

4/3 is the slope because it goes up 4 units and right 3 units from the y-intercept.

6 is the y-intercept, which is the y-coordinate. It can also be graphed as (0,6).
