Answer:

h = 2.12 , c = 6.93

Step-by-step explanation:

To calculate h:

Apply the cosine identity

[tex]cos\ x =\frac{base}{hypotenuse}\\\\cos\ 45=\frac{h}{3}\\\\0.707=\frac{h}{3}\\\\h=3(0.707)\\h=2.12\\[/tex]

To calculate c:

Apply the tangent identity

[tex]tan\ x=\frac{perpendicular}{base}\\\\tan\ 60=\frac{c}{4}\\\\1.732=\frac{c}{4}\\\\c=1.732(4)\\c=6.93\\[/tex]

Answer: 42

Step-by-step explanation:

Answer:

The answer is option D: 42.

Step-by-step explanation:

First we have to understand that for every 20 students there is one teacher we can find this form the ratio 20:1. Then we are given that there are 840 students. That means for every 20 students in the 840 there is one student. And, 840 divided by 20 equals 42. (please give brainliest)

Answer:

[tex]\frac{1}{8} = \frac{2}{16} < \frac{4}{24}[/tex]

Step-by-step explanation:

Since [tex]\frac{1}{8}[/tex] is already simplified, we do not need to change it in any way. Comparing it with [tex]\frac{2}{16}[/tex], which after simplifying is [tex]\frac{1}{8}[/tex], we can see that they are the same. Therefore, [tex]\frac{1}{8} = \frac{2}{16}[/tex].

Now. we compare [tex]\frac{2}{16}[/tex] with [tex]\frac{4}{24}[/tex]. We have already established that [tex]\frac{2}{16}[/tex] is [tex]\frac{1}{8}[/tex], so all we have to do is to simplify [tex]\frac{4}{24}[/tex] and compare it with [tex]\frac{1}{8}[/tex]. Simplifying [tex]\frac{4}{24}[/tex], we get [tex]\frac{1}{6}[/tex], which is larger than [tex]\frac{1}{8}[/tex]. Therefore, [tex]\frac{2}{16} < \frac{4}{24}[/tex].

Hope this helped!

Answer: 4/10

Step-by-step explanation:

Step-by-step explanation:

Angle at Center = 2 * Angle at Circumference

Let O be the center of the circle.

By using segment AC,

Angle AOC = 2 * Angle ABC = 2 * 75° = 150°.

Therefore the measure of arc AC is 150°.

Answer: 38 for x, 61 for bottom left angle, 81 for top angle.

Step-by-step explanation:

Since all angles must add up to 180 degrees, that means that (2x+5) + (2x-15)+x must equal to 180. If you add and simplify correctly, x equals 38. The other angles can be figured out once you found x.  

Step-by-step explanation:

Angle ADB + Angle BDC = 90° (right angle)

Since Angle ADB = Angle BDC,

Angle BDC = 90° / 2 = 45°.

Answer:

62.5 inches

Step-by-step explanation:

We would solve this using ratio

Width : Length = Width/Length

For the Original photo

5 inches : 7 inches = 5/7

For the enlarged phots

x : 87.5 inches = x/87.5

Equating both ratios together, we have:

5/7 = x /87.5

Cross Multiply

7x = 5 × 87.5

7x = 437.5

x = 437.5/7

x = 62.5 inches

Hence, the width of the enlarged photo is 62.5 inches

Answer:

The mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs.

Step-by-step explanation:

This questions implies that there is a need to fill in mathematical symbols that will this a true a equation.

A true equation can be described as situation whereby there the same values on the either sides of the equal sign "=". For instance, 5 + 1 = 6 is a true equation. Also,  4 * 2 = 8 is a true equation.

As regards this question, the mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs. When the multiplication signs are filled in between the numbers, we have the following true equation:

2802 * 1811 * 123 * 441 * 3633 * 1/3 * 32^2 * 205 = 69,972,637,305,761,000,000

Answer:

20%

Step-by-step explanation:

Probability of ordering large

= 5/(8 + 12 + 5) = 5/25 = 1/5

= 1/5 *100 = 20%

Answer:

5%

Step-by-step explanation:

Total outcome is 100

Favorable outcome is 5

The probability that a customer ordered a large cold drink is

[tex]\frac{5}{100}[/tex] = [tex]\frac{1}{20}[/tex] = 5%

Answer:

(a) GDP = $333.9 billion

(b) NDP = $322.1 billion

(c) NI = $307.7 billion

Step-by-step explanation:

(a) Compute GDP

This can be computed using the following formula:

GDP = Gross Domestic Product = Personal consumption expenditure + net private domestic investment + government purchases + (US exports of goods - US Imports of goods) ......... (1)

Substituting the values into equation (1), we have:

GDP = $219.1 + $52.1 + $59.4 + ($19.8 - $16.5) = $333.9

Since all figures are in billions, we have:

GDP = $333.9 billion

(b) Compute NDP

This can be computed using the following formula:

NDP = Net domestic product = GDP - Consumption of fixed capital ................... (2)

Substituting the values into equation (2), we have:

NDP = $333.90 - $11.8 = $322.1

Since all figures are in billions, we have:

NDP = $322.1 billion

(c) Compute NI

This can be computed using the following formula:

NI = National Income = NDP - Taxes on production and imports  - Statistical discrepancy ........... (3)

Substituting the relevant values into equation (3), we have:

NI = $322.1 - $14.4 - $0.0 = $307.7

Since all figures are in billions, we have:

NI = $307.7 billion

Answer:

Answer:

A sandwich costs $7.5

Step-by-step explanation:

Given

Represent chips with c and sandwiches with c

[tex]c = \$1.25[/tex]

[tex]Total = \$38.75[/tex]

From the question, we understand that 5 sandwiches were ordered.

Hence, the question of the system is:

[tex]5s + c = Total[/tex]

Substitute values for Total and c

[tex]5s + 1.25 = 38.75[/tex]

Collect Like Terms

[tex]5s = 38.75 - 1.25[/tex]

[tex]5s = 37.5[/tex]

Divide both sides by 5

[tex]s = \frac{37.5}{5}[/tex]

[tex]s = 7.5[/tex]
