Which of the following are true statements about the expression 7 - (-7)7−(−7)7, minus, left parenthesis, minus, 7, right parenthesis?

Answers

Answer 1

To evaluate the expression 7 - (-7), we can simplify it step by step:

Step 1: Simplify the expression inside the parentheses.

-(-7) = 7

Step 2: Substitute the simplified expression back into the original expression.

7 - (-7) = 7 - 7

Now, let's analyze the given statements:

The expression equals 0.

False. The expression 7 - 7 does not equal 0. It equals 0 when multiplied by (-7), but in this case, the multiplication is not part of the expression.

The expression equals 14.

False. The expression 7 - 7 equals 0, not 14.

The expression is equal to the absolute value of 7.

False. The absolute value of 7 is 7, but the expression 7 - 7 is 0, not 7.

The expression is equal to the opposite of 7.

False. The opposite of 7 is -7, but the expression 7 - 7 is 0, not -7.

Therefore, none of the given statements are true about the expression 7 - (-7).

Answers

Answer:

Answer A

Step-by-step explanation:

180° = 84° + (x + 46)°

(x + 46)°= 180° - 84°

x = 180° - 84° - 46° = 50°

(2x + 31)° = 131°

which means the next angle to it equals 180° - 131° = 49°

and as we know if we add up a triangle's angles it equals 180°

so the last unknown one is 180° - 84° - 49° = 47°

then a° = 180° - 47° = 133°

Answer:

A) 133°

Step-by-step explanation:

First, we solve for x.

84+x+46=180

130+x=180

x=50

Now, we plug that into 2x+31

2(50)+31=131

Then, 180-131 gives us an interior angle of 49.

Now we have two interior angles and can solve for the third.

180-84-49=47

Then we can find a by subtracting that from 180

180-47=133

What is a proportional relationship?

A proportional relationship is a type of relationship between two quantities in which they maintain a constant ratio to each other.

The equation that defines the proportional relationship is given as follows:

y = kx.

In which k is the constant of proportionality, representing the increase in the output variable y when the constant variable x is increased by one.

Caroline's equation is given as follows:

y = 44x.

Hence her car travels 44 miles on a gallon of gas.

Adrian's constant is given as follows:

k = 143.5/5 = 287/10 = 28.7.

Hence his car travels 28.7 miles on a gallon of gas.

Hence the difference is given as follows:

Answer:

Box A's volume is 384.75 cm^3 and Box B's volume is 295.75 cm^3. Box A's volume is greater than Box B's volume.

Step-by-step explanation:

This is a rectangular prism given that the box has different lengths.

Stated dimensions for each box,

Box A:

Length = 13 1/2 (13.5) cm

Width = 3 cm

Height = 9 1/2 (9.5) cm

Box B:

Length = 14 cm

Width = 3 1/4 (3.25) cm

Height = 6 1/2 (6.5) cm

All we have to do, is find the volume of each box, compare them to each other, and determine which volume in which box is the greatest.

Now, in order to find the volume of a rectangular prism, use the formula:

V = L · W · H

Where "L" represents length, "W" stands for width, and "H" represents height.

Given all of these values from the box's dimensions, we only have to plug it in this formula to find the volume.

Let's find Box A's volume:

V = L · W · H

Substitute values:

V = 13.5 · 3 · 9.5

V = 40.5 · 9.5

V = 384.75

Let's find Box B's volume:

V = L · W · H

V = 14 · 3.25 · 6.5

V = 45.5 · 6.5

V = 295.75

Compare the two values to see which is the greatest:

384.75 __ 295.75

384.75 > 295.75, Box A's volume is greater.

Now we know that Box A's volume is 384.75 cm^3 and Box B's volume is 295.75 cm^3. Box A's volume is greater than Box B's volume.

Answer:

(C) x = 56

Step-by-step explanation:

To find the value of x, we first need to find the measure of its supplement, or the angle which, when added to x°, results in 180°, or a straight line.

We can find the measure of its supplement by using the fact that the measures of the interior angles of a triangle add to 180°.

Hence, we can form the following equation to solve for the measure of the supplement.

37° + 19° + s° = 180°

s° = 124°

Now, we can subtract the measure of the supplement from 180° to get x°.

x° = 180° - 124°

x° = 56°

We can cancel the degrees on both sides of this equation to solve for x.

(C) x = 56

Falcons; they have a larger median value of 22.5 inches

Answers

Answer:

The team that has the largest overall size hat for their players is the Seahawks; they have a larger mean value of about 23 inches. The correct option is C.

Step-by-step explanation:

What is the mean and median?

The two most frequently used measures of center are mean and median. When we compare the mean numbers for the Falcons and Seahawks, we can see that the Falcons have a mean of roughly 22 inches and the Seahawks have a mean of roughly 23 inches.

Nevertheless, when the data is skewed or contains outliers, the mean may not be the best approximation of the center because the mean can be altered by extreme values or outliers. Thus, we also need to compare the median values. The median is the midway value in the ordered set of data.

Thus, the correct option is C, Seahawks; they have a larger mean value of about 23 inches.

The answer is 127cm

The second picture:

Part a (measurement):
Information given:
- An object on Mars is 70lbs weighs 210lbs on Earth
- An object weighs 160lbs on Earth, how much would it weigh on Mars?

Divide both sides by 42 (because 210 divided by 42 is 5 and 5 is a common factor in 160)
- 70lbs on Mars/42 = 1.6lbs
- 210lbs on Earth/42= 5lbs

It looks complicated but it isn’t!

1.6:5 ratio is given
Now multiply both sides of the ratio by 32
1.6 x 32= 51.2lbs on Mars
5 x 32 = 160lbs on Earth

The answer is 51.2lbs on Mars

To find the scale factor used to produce figure 1 from figure 2, we can divide the length of a leg in figure 1 by the length of the corresponding leg in figure 2.

Length of leg in figure 1 = 2 units
Length of leg in figure 2 = 6 units

Scale factor = Length of leg in figure 1 / Length of leg in figure 2 = 2/6 = 1/3

Therefore, the scale factor used to produce figure 1 from figure 2 is 1/3.
