Answer:

  29.4°

Step-by-step explanation:

The equation can be rearranged to give C directly.

  C = arccos((a^2 +b^2 -c^2)/(2ab))

  C = arccos((90^2 +55^2 -50^2)/(2·90·55))

  C = arccos(8625/9900) ≈ 29.4002°

  C ≈ 29.4°

Answer:

a) 15 + 25x ≤ 70

b) 60 + 15x ≤ 500

Step-by-step explanation:

a) Let x represent the number of calculators that Ms. Burgos can buy. since each calculator cost $25, then the total cost of calculator = $25 * x = $25x

She bought three notebooks costing $5 each. Money spent on notebooks = 3 * $5 = $15

Hence the total money spent = $15 + $25x = 15 + 25x

She has only $70, therefore:

15 + 25x ≤ 70

b) Cayla initially has $60.

Cayla is saving $15 per week. Let us assume she saves for x weeks, hence money saved by Cayla = 15x

Therefore the total money saved = 60 + 15x

Since Cayla needs to save atleast $500, hence:

60 + 15x ≤ 500

Answer:

Total weight = 1,500 tons

Step-by-step explanation:

Given:

l = 5 ft

b = 5 ft

h = 6 ft

One cubic foot weighed = 0.1 tons

Find:

Total weight

Computation:

Volume = lbh

Volume = (5)(5)(6)

Volume = 150 ft³

Total weight = Volume / 0.1

Total weight = 150 / 0.1

Total weight = 1,500 tons

Answer:

[tex]2x^2+16x+29[/tex]

Step-by-step explanation:

Given that,

[tex]g(x)=2x^2-5[/tex]

We need to find g(x+4)+2

[tex]g(x+4)=2(x+4)^2-5\\\\=2(x^2+16+8x)-5\\\\=2x^2+32+16x-5\\\\=2x^2+16x+27[/tex]

Now,

[tex]g(x+4)+2=2x^2+16x+27+2\\\\=2x^2+16x+29[/tex]

So, the value of [tex]g(x+4)+2[/tex] is  [tex]2x^2+16x+29[/tex]

Answer:

15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.

Step-by-step explanation:

Length, Area, and Volume Scale Factors

If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is [tex]a^2:b^2[/tex] and the scale factor of their volumes is [tex]a^3:b^3[/tex].

We are given the scale factor of the surface areas of two similar containers A and B as 4:25.

The length scale factor is

[tex]\sqrt{4}:\sqrt{25}=2:5[/tex]

The volume scale factor is: [tex]5^3:2^3[/tex] = 125:8 = 15.625

Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

Thus, after she pours the 15th container, in the middle of the next one, the work will be done

Answer:

y = .25 x 96

y = 24

This is the answer.

Step-by-step explanation:

25% is the same as 0.25

25% = 25/100 = 0.25

Multiply 0.25 with 96

0.25 x 96 = 24

24 is your answer

Answer:

angle 7 = angle 3 because corresponding angles r equal

Answer/Step-by-step explanation:

Given, y = k√x

Let's find the following:

a. To find k, using the first pair given, (64, 16), plug in the values of the ordered pair into y = k√x

Thus:

16 = k√64

16 = k*8

Divide both sides by 8

16/8 = k

k = 2

b. To find F, substitute k = 2, and x = 100 into y = k√x

Thus:

y = 2√100

y = 2*10

y = 20

F = 20

c. To find x, substitute k = 2, and y = 10√2 into y = k√x.

Thus:

10√2 = 2√x

Divide both sides by 2

(10√2)/2 = √x

5√2 = √x

Square both sides

x = (5√2)²

x = 25*2

x = 50

d = 50

Answer:

Jaycee sold 28 candy bars

Step-by-step explanation:

Jayce and Rylee are selling candy bars for a school fundraiser. Rylee sold 84 candy bars and raised $210. If Jayce raised $70, how many candy bars did he sell?

From the above question:

$210 = 84 candy bars

$70 = x candy bars

Cross Multiply

210 × x = 70 × 84

x = 70 × 84/210

x = 28 candy bars

Therefore, Jaycee sold 28 candy bars

From the description of the construction of the congruent angle, we have;

The statement that describes step 3 correctly is; Use the same width of the compass to draw an arc from point N that intersects the segment AN at a point X

The reason for making the above selection is as follows:

The steps to construct an angle congruent to another angle are;

Step 1: Given an angle PQR, draw a working segment NT

Step 2: Place the needle of the compass at point Q and draw an arc (Q, QA), intersecting sides PQ and QR of the angle ∠PQR at points A and B respectively

Step 3: Place the needle of the compass at point N and draw an arc with the compass width QA from above the to intersect the segment NT at a point X

Step 4: Set the compass width to the distance AB with which an arc is drawn from point X so as to intersect the arc (N, QA) above at point Y

Step 5: The points Y and N are joined with a straight line to form the congruent angle

Analysis of the steps:

Given that in step 4, we have that the the arc drawn from point X with compass width AB is meant to intersect the arc drawn from point N, at point Y, we have that in step 3 an arc was drawn from point N with compass width QA from step 2 to intersect NT at a point X

Therefore;

Step 3 is best described by the following statement;

Use the same width of the compass to draw an arc from point N that intersects the segment AN at a point X

Use the same width of the compass to draw an arc from point N that intersects the segment NT at a point X.

This option gives us the step 3.

This is because we want to have equal angles. Therefore we select an arc equal in length to arc AB which intersects NT at  point X.

This can be explained more with the help of a diagram.

Two angles are equal when their dimensions are equal.

Arcs of equal length would give congruent angles.

Highest Possible Perimeter = 52cm

Step-by-step explanation:

The triangle is not shown. But, the question can still be solved.

The given sides (5cm,12cm and 13cm) of the triangle shows that the triangle is a right angled triangle as proven below:.

[tex]13\² = 5\² + 12\²[/tex]

[tex]169 = 25 + 144[/tex]

[tex]169 = 169[/tex]

Having shown that;

The next step is to determine the highest possible value of the perimeter.

To get the highest possible perimeter;

The 4 triangles have to be joined at the 12cm and 5cm part of each triangle (see attachment).

From the attachment, the perimeter is then calculated as:

Perimeter = 13cm + 13cm + 13cm+ 13cm

Perimeter = 52 cm

Answer:

16 cups is equal to 4 quarts

Step-by-step explanation:

Multiply the volume by 4

The required  4 quarts are equal to 16 cups. This means that if you have 4 quarts of liquid, you can pour it into 16 cups and it will completely fill them. Option D is correct.

1 quart is equivalent to 4 cups. This is a standard conversion ratio between quarts and cups. It means that if you have 1 quart of liquid and you want to know how many cups it is, you can simply multiply the number of quarts by 4.

So, to find out how many cups are in 4 quarts, we perform the following calculation:

4 quarts * 4 cups/quart = 16 cups
