Answer:

8 plantains

Step-by-step explanation:

48=$24

x=. $4

192=24x , x= 192÷24= 8

Answer:

8 plantains

Step-by-step explanation:

Cost and number of plantains are in proportion

Number of plantains that can be bought for $ 4 be 'x'

48 : 24 :: x : 4

Product of means = product of extremes

24 * x = 48*4

       [tex]x = \frac{48*4}{24}[/tex]

      x = 2 * 4

      x = 8

Answer:

r=7

Step-by-step explanation:

74000=28000(1+r/12)^12(14)

divide 74000 by 28000, and cancel out 28000.

1.00580=1+r/12

(100) .06962=r

r = 6.96198

the 6 after the 9 rounds 9 to 0, which rounds the 6 to 7

r=7

Answer:

there is a 13 degree difference from DBC and DAC

 with that you divide 1540 by 13 as you get that 118.461 feet

that means that there is a 118.461 difference from B to C and A to B

so the answer is either 1658.461ft or 1421.539ft I am not sure if that is correct or not but best of luck mate

Answer:

C: step 2 (Took the test on edge got 100%)

Step-by-step explanation:

Your question was incomplete you have forgotten to include the graph necessary to answer.

Answer: x=8

Step-by-step explanation:

We know that it is a square, so the diagonals divide the four triangles evenly.

A whole circle will have 360°. When it is divides into 4, each angle will be

360/4=90°

The vertex of each triangle will be 90°

And the given vertex equation is 8x+26

8x+26=90

8x+26-26=90-26

8x=64

x=8

Hope this helps!! :)

Answer:

98

Step-by-step explanation:

Hello There!

The angle that has a measure of 82 degrees and the angle labeled "2" are supplementary angles.

This meaning that the sum of the two angles is 180

So to find the missing angle (2) we subtract the given angle (82 in this case) from 180

so ∠2 = 180 - 82

180 - 82 = 98

Hence, the answer is 98°

The answer is "Fail to reject [tex]H_o[/tex], because  [tex]w_o[/tex] is sufficient evidence for claim".

Step-by-step explanation:

[tex]H_0 \mu=2638.0 \ \ / \ \ H_a \mu \neq 2638.0 \\\\\mu < 2638.0 \ \ or \ \ \mu > 2638.0 \\\\\alpha =0.05 \ \ level \ \ at \ \ sufficient \\\\[/tex]

Test Statistic:

Answer:

384 cm²

Step-by-step explanation:

Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.

[tex]\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height }[/tex]

Area of a triangular face

= ½ ×12 ×10

= 60 cm²

[tex]\boxed{area \: of \: square = side \times side}[/tex]

Base area of pyramid

= 12 ×12

= 144 cm²

∴ Surface area of pyramid

= 4(60) +144

= 240 +144

= 384 cm²

Answer:

c. We are 95% confident that, among the population of students that play basketball recreationally, the proportion who live on campus is between 0.12 and 0.18.

Step-by-step explanation:

According to the question, it is mentioned that there is 95% confidence interval and it is calculated (0.12,0.18)

So the correct interpretation is that they are 95% confident that the students who play basketballs the proportion should lies between 0.12 and 0.12

So, the option C is correct

The rest of the options are wrong

Answer: 950. 042553

Step-by-step explanation: Calculator

9514 1404 393

Answer:

Step-by-step explanation:

The number of filled bags will be 35 for each hour (x) that Jackson works, in addition to those already filled. So, the total number filled after x hours is ...

  35x + 20

We want that number to be at least (greater than or equal to) 1000, so the relation is ...

  35x +20 ≥ 1000

__

To solve this, we first subtract 20:

  35x ≥ 980

Now, we can divide by the coefficient of x.

  x ≥ 980/35

  x ≥ 28 . . . . .  the solution

Chapter Three: Calculate Total Countertop Square Footage

To calculate the total square footage (after placing seams) you will need to follow this formula: “L” x “W” / 144 = s.f. (Length times width divided by 144 = square feet).

Answer:

$340

Step-by-step explanation:

Given data

Inititial fee= $100

cost per minute= $1

Let the total charge for x minutes by y

Hence the expression for the total charges after x minutes is

y= 100+1x

y=100+x

But an after is from 12pm - 4pm= 4 hours

x=4*60

x=240minutes

y=100+240

y=$340

Answer:

  48 minutes

Step-by-step explanation:

The average speed for stage 1 is ...

  speed = distance/time = (110 mi)/(2 h) = 55 mi/h

Then the time for stage 2 is ...

  time = distance/speed = (44 mi)/(55 mi/h) = (4/5 h)(60 min/h) = 48 min

The time for stage 2 is 48 minutes.

Answer:

We know that

SpeeD = Distance/Time

Speed = 110/2

Speed = 55 mi/hr

For, 2

Speed = 44/55

Speed = 4/5

Speed = 48 min
