Answer:

Step-by-step explanation:

I'm not sure what you mean by those steps mean but here is how I would answer using the elimination method:

3x - 12y = 5

minus (each term separately: 3x - 3x, -12y - -y, and 5 - 9)

3x - y = 9

This eliminates the 3x and = -11y = -4

You can then simplify from there and get y = 4/11

Answer: p = 115* (degrees)

What we know:

How to solve:

    By finding the degree of the 3rd angle in the right triangle, we can use the rules of supplementary angles to find the value of p.

    We will use D to represent the total amount of degrees, which will equal 180*. X will represent an unknown angle. An asterisk represents the degree symbol.

Missing right triangle angle

Set up equation                                                     D = 25 + 90 + x

Substitute                                                            180 = 25 + 90 + x

Simplify                                                                180 = 115 + x

Isolate variable                                                   -115    -115

Solution                                                               65* = x

Value of p using supplementary angles

Set up equation                                                     D = x + p

Substitute                                                           180 = 65 + p

Isolate variable                                                 -65     -65

Solution                                                              115* = p

Check:

We can do a check based on estimation. Assuming that the trapezoid and triangle form a box with all 90* corners and that p = 115*, then adding p and all of the other trapezoid angles should result in 360*

Firstly, we need the values of these 4 angles.

The first angle, labeled p, should be 115*. If our equation is untrue, then this value will fail the check.

The second angle will be the one at the bottom-left, which is 90* according to our box statement.

The third angle is the one located at the bottom-right, which is also 90* from the box statement.

The fourth angle is not 90* or 115*, but we can solve its value.

Because we have stated that the right triangle and trapezoid form a box with 4 90* corners, the sum of the fourth angle and the 25* from the right triangle must form a right angle. Let's find the value:

D = 25 + x

90 = 25 + x

(90 = 25 + x) - 25

65* = x

Therefore, the fourth angle has 65*

Now, adding the degrees from all 4 angles should result in a total of 360*. If it does, then our value of p = 115* will pass the check.

D = 90 + 90 + p + x

360 = 90 +90 + 115 + 65

360 = 180 + 180

360 = 360

Therefore, p = 115*

Answer:

C

Step-by-step explanation:

A and B are out because we can already tell that 65 and 75 are smaller than the 90 degrees whichs this angle is even higher than.If you see or use a protrater you can see it seems more likely to 115 because 155 would be much more open.

Answer:

[C] [tex]\frac{6\;days}{x\;Hours}=\frac{1\;day}{24\;Hours}[/tex]

Step-by-step explanation:

Since, we know that

1 Day = 24 Hours

6 Days = x Hours

Cross Multiply:

6 x 24 = 144

1x = 144

x = 144

144 = 144

Hence, the best answer is [C] [tex]\frac{6\;days}{x\;Hours}=\frac{1\;day}{24\;Hours}[/tex]

~lenvy~

The following proportions could be used to convert 6 days to hours as 1 day : 24 hours :: 6 days : x hours.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

There is a way to convert 6 days to hours, to use the proportion:

⇒ 1 day : 24 hours :: 6 days : x hours

This proportion shows the relationship between days and hours, and can be used to convert from one unit to the other. To solve for x, we can cross-multiply and divide:

x = 6 days × 24 hours / 1 day = 144 hours

So, 6 days is equivalent to 144 hours.

Hence, the correct answer would be an option (C).

Step-by-step explanation:

1 hour = 60 mins.

60 + 60 + 60 + 60 = 240 mins.

4 pm to 8 pm is 4 hours.

Answer:

Hi!

So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.

For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.

Hope this helps! :)

Answer:

Count the distance across from point A to point B

To make this easier, bring point B to the same height level as point A then count the units over.

If we bring point B two units up, we can see that the distance between point B and A is 6 units apart.

The horizontal flat box has dimensions of

h = 2

w = 7

l = 21

The vertical box has dimensions of

h = 10

w = 7

L = 12

Formula

V = L * w * h

Solution

Horizontal Flat Box = L*w * h

Horizontal Flat Box = 21 * 7 * 2

Horizontal Flat Box =                                           294

Vertical Box

Vertical Box = L * w * h

Vertical Box = 12*7 * 10

Vertical Box =                                                      840

Answer:

44

Step-by-step explanation:

45-1=44

Answer=44

Hey there!

Let's solve this equation for N.

First, let's work out 36+9:

45

45-N=1

subtract 45 from both sides:

-N=1-45

-N=-44

Divide both sides by -1:

N=44 (Option B)

Answer:

The answer is 23 because they have to add up to 90-kai :)

Step-by-step explanation:

So, ∠a + ∠b = 90°

67° + ∠b = 90°

∠b = 90° - 67°

∠b = 23°

Answer:

The measure of ∠b is 23°.

Step-by-step explanation:

Complementary angles are angles that add together to always be 90°. The problem gives us this information at the start:

∠a + ∠b = 90°

∠a = 67°

You can apply this information to the equation by getting the problem of:

67° + ∠b = 90°

To solve this equation you simply rearrange the terms, and subtract 67 from 90:

90° - 67° = ∠b

After rearranging the terms and subtracting 67 from 90 you are left with the following result:

∠b = 23°

Answer:

Each additional copy increased the time by 8 seconds

Step-by-step explanation:

It is increased because- the amount of seconds is increasing every time an additional copy is added to the table

it is 8 because- 12 increases by 8 to get 20, and 20 increases by 8 to get 28, and 28 increases by 8 to get 36.

Answer: 3/52 (~5.77%)

What we know:

How to solve:

  We need to find the probability of drawing one of 3 diamond face cards, which gives us all of the information we need. Using division, we can create a 'x amount of diamond face cards/y amount of total cards' probability.

Probability of a diamond  face card

Where P is the probability of drawing that card, x is the number of diamond face cards, and y is the total amount of cards.

Set up equation                                                     P = x/y

Substitute                                                               P = (3)/(52)

Answer: 3/52 (~5.77%)

Because there are 3 diamond face cards in the deck, the chance of drawing one is {3 cards out of 52 total}, which is 3/52.

The chance of drawing ANY face card is {(3 per suit, 4 suits=) 12 cards out of 52 total} 12/52 (~23.08%),

The chance of drawing ANY diamond card is {1 suit out of 4 suits} 1/4 (25%)

Answer:

30

Step-by-step explanation:

Given:

QR= 45 mm

RS= 15, (1/3 of QR is 15).

QT is 90 mm

We must find ST.

Equation:

Use Segment Addition Postulate Theroem,

QR+RS+ST=QT

Subsitue the values we know

45+15+ST=90

60+ST=90

ST=30So ST length is 30 m

Answer:

7%

Step-by-step explanation:

First, let's add the 20 dogs and 15 cats together to find the total number of animals adopted

20 + 15 = 35 animals adopted

We cand do 35 ÷ 200 to find how much of a percent 35 is of 500

35 / 500 = 0.07

Multiply this number by 100 to get a percent

0.07 × 100% = 7%

7% of the animals
