Answer:
(a) A = 1/2bh
(c) A = bh
Step-by-step explanation:
You want the formulas for the area of a triangle and the area of a parallelogram.
Area formulasThe formula for the area of a triangle is ...
A = 1/2bh
The formula for the area of a parallelogram is ...
A = bh
__
Additional comment
The formula for the area of a trapezoid is ...
A = (1/2)(b₁ +b₂)h
A trapezoid is a quadrilateral with two parallel sides. These parallel sides are the bases, b₁ and b₂.
A parallelogram has bases of the same length. Using that fact in the formula gives ...
A = (1/2)(b +b)h = (1/2)(2b)h = bh . . . . area of a parallelogram
In a triangle, one of the bases is zero length. Using that fact in the formula gives ...
A = (1/2)(b +0)h = 1/2bh . . . . area of a triangle
The perimeter of a rectangle has the formula ...
P = 2(b +h)
It should not be confused with an area formula.
Which of the following are true statements about the expression 7 - (-7)7−(−7)7, minus, left parenthesis, minus, 7, right parenthesis?
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).

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.
Solve this system of equations using the substitution method.

Answer pleaseeeeeeee
Answer: B
Step-by-step explanation:
Let's do each equation to find which has the value of 128. A is 2 to the power of 7 means you multiply 2, 7 times, so 2 times 2 is 4, 4 x 2 = 8, 8 x 2, 16, 16 x 2 = 32, 32 x 2 = 48, and 48 x 2 is 96, so answer A is incorrect. B is 2 times 4 to the power of 3 so 4 x 4 is 16 and 16 x 4 is 64, since I have to multiply that number by 2, I get a total of 128. Well that's the answer so the others are incorrect ( A, C, and D). Hopefully this helps :)

The scatter plot shows the relationship between the amount of time, in hours, students in a Spanish class slept the night before an exam and their score on the exam.
Which of the following describes the pattern of association for the scatter plot?
There is a positive linear association.
There is a positive nonlinear association.
There is a negative linear association.
There is a negative nonlinear association.
Answer: Positive Nonlinear Association
Step-by-step explanation:
Take a look at the graph. From what we can see, it is going up. Hence, it's positive (meaning C and D are not the answer).
The way to tell between linear and nonlinear is the line. If you can perfectly fit all the points on a straight line, then it is linear. Clearly, you can't fit all the points on a singular straight line here, so it is nonlinear.

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
