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

y=-3x+13

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:

Step-by-step explanation: 90

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

Answer:

Rhombus, parallelogram, trapezoid, rectangle

C. quadrilateral, trapezoid; trapezoid

Step-by-step explanation:

This is a quadrilateral, it has 4 sides, it is not a rhombus because its sides aren't equal, it isn't a parallelogram because only two of its sides are parallel

Answer: 20°

Step-by-step explanation:

There is 180 degrees in the triangle.  ∠C is 50°,  ∠A is 80°,  ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.

Answer: 20 degrees

Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :

80 + 50 = 130

subtract that from 180 to find out what angle ABC is:

180 - 130 = 50

since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:

50 - 30 = 20

angle DBC = 20 degrees

Answer:

37.68

Step-by-step explanation:

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:

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

Answer:

it’s around 80°

explanation:

a little bigger than 73°. How ever, not quite a right angle (90°)

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

Answer:

The median is 7.

Step-by-step explanation:

In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).

I'm gonna do both as an example.

Greatest to least:

14, 13, 9, 9, 7, 5, 3, 2, 1

Least to greatest:

1, 2, 3, 5, 7, 9, 9, 13, 14

It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.

The next thing you need to do is find the number that is in the middle.

It will be the same for both least to greatest AND greatest to least.

You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.

In this case, your answer goes like this:

since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.

In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.

I hope this helped you!

Have a great dayyyy

Answer: .4m

Step-by-step explanation:

move decimal over

Answer:

⅖ m or 0.4 m

Step-by-step explanation:

1 m [meter(s)] = 100 cm [centimeter(s)].

_____________________________

(x) m = (100)(x) cm

(100)(x) = 40

x = 40 / 100

x = 4 / 10 = 2 / 5

x = 0.4
