Answer:

A = 168 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 8 + 16 = 24 and h = 14 , then

A = [tex]\frac{1}{2}[/tex] × 24 × 14 = 12 × 14 = 168 m²

Find the x-intercept of the function y=−0.2x+0.55

Answers

Answer:

2.75

Step-by-step explanation:

y=0

−0.2x+0.55=0

0.2x=0.55

x=2.75

Answer:

x=-2.75

Step-by-step explanation:

Plug y=0 into the equation and solve for x:

y=-0.2x+0.55

0=-0.2x+0.55

-0.55=0.2x

-2.75=x

Therefore, x=-2.75

Teresa is maintaining a campfire. she has kept the fire steadily burning 4 hours with 6 logs. She wants to know how many logs she need to keep the fire burning for 18 hours. Select the equations tessa can use, and determine the number of logs she needs to maintain the fire for 18 hours. Select all that apply.

A. X/6=4/18
B. X/6=18/4
C. X/18=6/4
D. X/4=18/6
E. 4/6=18/X

Answers

D. X/4=18/6

Step-by-step explanation:

Let x be the number of logs=18 hours

6 logs=4 hours

X*4=18*6

4x=108

x=27 logs

so therefore 27 logs are needed to keep the fire burning for 18 hours

Step-by-step explanation:

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55

Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

I really need help finding the surface area

Answers

There are 4 triangles and the formula for the area of a triangle is 1/2BH so 11x10 is 110 and then take half of that and you’ll get 55. Since there are 4 triangles you need to then multiply that by 4 to get 220. And then you have to find the area of the square base which is 11x11 which will come out to 121. So you add the 220 and 121 to get 341.

cos theta = ------------------- = 18/20. Find theta:

theta = arccos 18/20 = 0.451 radian.

Now use the sine function to find x:

x x

sin 0.451 radian = ------------------- = ------------- = 0.651

hypotenuse 20

which results in x = 20(0.651) = 13.02

x = 13.02 units

I should have used the Pythagorean Theorem up front.

18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?

Part A

Which equation represents the situation?
0.75s = 31.50
34(18s) = 31.50
0.75(s + 31.50) = 18
34(18 + s) = 31.50
Part B

Use the Distributive Property to solve the equation.

Answers

Answer:

`Part A:

D. 3/4(18 + s) = 31.50

Part B:

$36

Step-by-step explanation:

I think 34 is 3/4, is that right?

here, s is the cost of the skirt

Part A: The answer would be:

3/4(18) + 3/4(s) = 31.5 =

3/4(18 + s) = 31.5

Part B: 3/4(18) + 3/4(s) = 31.5

4.5 + 3/4s = 31.5

Subtract 4.5 from both sides:

3/4s = 27, 27 is the cost of the skirt now, but we need the original price.

multiply both sides by 4/3:

s = 36

what is the area of the triangle?

Answers

Answer:

S = S(ABCD) - S(BCE) - S(AED) = 7*6 - 2*6/2 - 5*6/2 = 42 - 6 - 15 = 21

Step-by-step explanation:

If we look at the picture, we can notice that the area we are interested in is S(ABCD) - S(BCE) - S(AED). Y-axis is parallel to AB line since the coordinates of the A and B points have the same X-axis value.

The following calculations happend for figuring out the width for each line:

AB = | -3 - 4 | = 7BC = | -4 - 2 | = 6CE = | 4 - 2 | = 2ED = | 2 - (-3) | = 5AD = | -4 - 2 | = 6

The formulas for each figure area:

S(ABCD) = AB * BCS(BCE) = BC * CE / 2S(AED) = ED * AD / 2

i agree that it is 21

True or false: The cross section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.

Options:
True
False

Answers

True, because it’s not certain it will be symmetrical.

True, as there is no guarantee that it will be symmetrical.

What is Geometry?

Geometry is defined as the study of two-dimensional or three-dimensional figures like quadrilaterals, Triangles, circles their sides, and angles.

Symmetry is defined as if the object is cut by its center line the two cut parts should be the mirror image of each other so that we can call them symmetric to each other.

Depending on the cut's direction (horizontal or vertical), a 3D object's cross-section may appear differently.

Therefore, the given statement is true that the cross-section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.

Solve for x

Answers

Answer:

x = 156

Step-by-step explanation:

These angles are supplementary so they add up to 180:

x - 5 + 29 = 180

x + 24 = 180

x = 156

Answer:

x = 156

Step-by-step explanation:

The line equals 180 degrees, and the angle 29 degrees is already given.

180-29 = 151

This means that the other angle must be 151 degrees.

(x - 5)°

If we replace 156 with x, we will get 151 degrees, so that means x = 156.

(156 - 5)° = 151°

A. It shows the unit rate of the graph in hours per mile
B. It shows the unit rate of the graph in miles per hour.
C. It shows the time, in hours, it takes the towboats to travel in 1 mile.
D. It shows the distance traveled, in miles, by the towboat after 5.25 hours.

Answers

I think the Answer is D

The answer is B because the hours would be the bottom intervals of 1 and the distance traveled (in miles) is the constant of 5.25. So, overall in one hour, you would’ve traveled 5.25 miles. (It’s like driving a car... you’d be going at a speed of 5.25 mph (which is kinda slow).
