Help I Really Dont Understand This :')btw Its X + 15 Not 25 I Messed Up

Answers

Answer 1

x = 10°

ABC = 65°

CBD =  25°

==============

Both the angles lie inside of right angle triangle whose interior angle sums up to total 90°

Solve for x :

4(x) + 25 + x + 15° = 90°4(x) + x + 25 + 15 = 90°5(x) + 40° = 90°5(x) = 90° - 40°5(x) = 50°x = 10°

====================

ABC = 4(x) + 25 = 4(10) + 25 = 65°CBD = x + 15° = 10 + 15° = 25°
Answer 2

Answer:

See below ↓↓↓

Step-by-step explanation:

∠ABC and ∠CBD are complementary⇒ ∠ABC + ∠CBD = 90°⇒ 4x + 25 + x + 15 = 90⇒ 5x + 40 = 90⇒ 5x = 50⇒ x = 10

∠ABC = 4x + 25∠ABC = 4(10) + 25∠ABC = 65°

∠CBD = x + 15∠CBD = 10 + 15∠CBD = 25°

Step-by-step explanation:

add the first [tex]x[/tex] coordinate plus the second [tex]x[/tex] coordinate

then divide them both by 2

[tex]y[/tex]= -7+2= -5 / 2 = -2.5 or four one half -2 1/2

BUT we are not done here, since we cant divide 1/2 no more because it will still give us the same answer (0.5) we move into the next number, -2 1/2, -2 x 1/2 = -1

15) Joe had 1 /4 of an acre of land. He wanted to plant 3 different types of vegetables in equal amounts of space. How much land will he use for each type of vegetable?

Answers

Answer:

1/12 land would be used for each type of vegetable

Step-by-step explanation:

First, Joe has 1/4 of an acre of land and 3 different types of plants he wants to plant for equal distance within that area. To find out the land he will use for each type of vegetable you must divide 1/4 by 3

The simplest way to divide fractions is to use cross multiplication

1         1        1

_   x   _  =    _

4        3       12

Therefore 1/12 of an acre is the amount of land he will use for each type of vegetable.

To check this just multiply 1/12 by 3 giving you 3/12 which can be simplified back into 1/4

1/12 should be the correct answer

Kira has to carry 170 apples from a farm to the market. How many baskets will she need, given that each basket can hold 46 apples?

Answers

Answer:

4 baskets

Step-by-step explanation:

Since 170 divided by 46 equals 3 with a remainder of 32, you use the remainder,32, and change it to one more basket so 3+1=4 so Kira needs 4 baskets.

Answer:

Kira will require exactly four baskets.

Step-by-step explanation:

The given information we know is..

- Kira is responsible for transporting 170 apples from a farm to the market.

- Each basket has a capacity of 46 apples.

We must divide 170 apples by 46 apples in order to solve this problem.

170/46 ( When I use the / symbol, it indicates to divide.)

170/46 = 3.69565217391

We'll have to round it up because we can't actually accept 3.69 bags. So the answer is 4 baskets.

Kira will need approximately 4 baskets.

Answer:

Step-by-step explanation:

To get from 27 to 21, you subtract by 6. To get from 21 to 15, you must also subtract by 6. Therefore, subtracting by 6 is the pattern. In order to get the next number in the sequence, we must subtract 6 from 15.

15 - 6 = 9

The next number is 9. To find the number after 9, we must do the same thing - subtract 6 from 9.

9 - 6 = 3

The 5th number of the sequence is 3.

Therefore, to find the number of throws Quinn made, we need to find 1/6 of 18, then subtract this from 18 (the number of throws Alex made).

1025.
To find the equation, you have to know the slope (5x) and the y intercept (25)
(Formula: y=mx+b) It says the input= x.
So plug 200 for x
5(200)+25=1025

The value of output for value of input of 200 is,

⇒ y = 1025

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The table shows the outputs for several inputs.

Now, We can find the expression for the table as;

Take two points are (0, 25) and (1, 30)

Hence, The equation is,

y - 25 = (30 - 25) / (1 - 0) (x - 0)

y - 25 = 5x

y = 5x + 25

Hence, The value of output for value of input of 200 is,

y = 5 × 200 + 25

y = 1000 + 25

y = 1025

Thus, The value of output for value of input of 200 is,

⇒ y = 1025

About 14 weeks ago, there were 42 mold spores found in a garden. After a few weeks of observation, it is determined that the number of mold spores in the garden is tripling every 7 weeks.


The number of mold spores, M, at any given time in the garden is equal to the product of the initial amount of spores, I, and 3 to the power of n, where n is the number of times the amount of mold spores has tripled.

Answer b because how it’s formed

Im guessing 252 is the answer, 42 mold spores were found 14 weeks ago and each 7 weeks it trples right? so two 7 weeks fit in 14 weeks so we would multiply 42 x 2 and which gives us 84 multiply that by 3 since it triples every 7 weeks.

Draw the rectangle on the coordinate plane.

(If you could please graph this as a coordinate plane and not numbers)

Answers

Answer:

(4,2) and (-4,2)

Step-by-step explanation:

You can see that we have 2 points, which means we have 2 sides of the rectangle. The length of that side is 8. we know that a rectangle has 2 sets of parallel sides, and that they have 2 sets of equal sides. We now know that there are 2 sides with side lengths equaling 16, which we then subtract from 20. We get 4, which we then divide by 2 because there will be 2 more sides. We then move 2 down from both points and take the point which we get from that, which is (4,2) and (-4,2).
