4. Find the surface area. Help me please

Answer:

Step-by-step explanation: 90

Answer:

part A is 512 square ft and part B is 3 cans

Answer:

70 - 79

Step-by-step explanation:

The mode interval is the interval with the largest frequency.

From the heights of the bars we see that this is 70 - 79

Answer:

r(t) = 75 kg - (4.5 kg/wk)w

Step-by-step explanation:

Let r(t) represent the amount of rice remaining after w weeks.

Then:

r(t) = 75 kg - (4.5 kg/wk)w

please mark as brainliest

Answer:

w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.

Step-by-step explanation:

r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.

75-4.5w=30

75-75-4.5w=30-75

-4.5w=-45

-4.5w/-4.5 = -45/ -4.5

w=10

Apologies if the explanation isn't thorough, I'll glady provide more details if necessary.

Answer:

volume = 143.1 m^3

Step-by-step explanation:

here's your solution

=> volume of cuboid = area of base * height

=> volume = 53*2.7

=> volume = 143.1 m^3

hope it helps

Answer is below. Look at the explanation to understand my answer.

To find the volume, you simply multiply all the lengths up to get your answer.

The formula is for finding the volume of a rectangular prism is: L × W × H. Normally there is 3 lengths, but there is only 2. We can still solve by using the same formula, instead of L × W × H, the formula will be Base Area × Height or BA × H.

Here is a breakdown: Solving for a Cuboid (rectangular prism) is easy; all you need to do is multiply all the units.  

With that being said...

53 times 2.7 is 143.1 m²

Therefore, 143.1 is the volume

Let me know of questions or concerns about my answer.

Formulas:

V = L × W × H (Length × Width × Height)

V = BA × H (Base Area × Height)

Answer: yes

Answer:

Yep, that's correct

Step-by-step explanation:

Answer:

We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.

Since it takes Angel 2 minutes to run 1 lap, she will take

2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.

So it takes Angel 5 minutes to run 1 km.

Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden

2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.

So it takes Jayden 416 minutes to run 1 km.

Step-by-step explanation:

i actually dont know what the answer-answer is but i think this will help alot.

Answer:

Step-by-step explanation:

Distance traveled in 2 minutes by Angel = 2/5 kilo meter

Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2

                                                                 [tex]=\frac{2}{5}*\frac{1}{2}[/tex]

                                                                 = 1/5 kilometer

Hi, there! I'd love to help you out!

We know complementary angles add up to 90 degrees.

Let's say our first angle is x:

x = first angle

It tells us the other angle is 68 degrees more. So we are just adding 68 to our other angle:

x = first angle

x + 68 = second angle

Now add the two and set it equal to 90 degrees:

x + x + 68 = 90

2x + 68 = 90

-68 -68

2x = 22

/2 /2

x = 11 first angle

x + 68 = 11 +68 = 79 degrees second angle

I hope this explanation helps you . (by the way is there a picture?)

Answer: 15

Step-by-step explanation:

x = one point shots

y = two point shots

1) Setup your equations.

x + y = 52

x + 2y = 89

2) Isolate a variable.

x = 52-y

3) Plug in.

(52-y) + 2y = 89

52 +y =89

y=37

4) Solve for x.

x = 52 -37

x=15

5) Check your answer.

15 + 2(37) = 89

15+74=89

89=89

37+15 = 52

52=52

x = one point shots

y = two point shots

1) Setup your equations.

x + y = 52

x + 2y = 89

2) Isolate a variable.

x = 52-y

3) Plug in.

(52-y) + 2y = 89

52 +y =89

y=37

4) Solve for x.

x = 52 -37

x=15

5) Check your answer.

15 + 2(37) = 89

15+74=89

89=89

37+15 = 52

52=52

Answer:

34.04 cm²

Step-by-step explanation:

Formula for a trapezoid:

a + b ÷ 2 × height

Substitute the values:

11.7 + 3.1 = 14.8

14.8 ÷ 2 = 7.4

7.4 × 4.6 = 34.04

The answer is 34.04 cm²

Answer:

x-int is 24/5 y-int is 8 and x value when y is 3 is 3

Step-by-step explanation:

So for the x int, we can plug in 0 for y, because in a x intercept, the y is zero.

5x=24

x=24/5

for the y int, we can plug in 0 for x, because in a y intercept, the x is zero.

3y=24

y=3

now when y is 3, we can just plug that in.

5x + 3 times 3 = 24

5x+9=24

5x=15

x=3

hope this helps
