The dimensions of triangle B are twice the dimensions of triangle A. The area of triangle A is 28 cm2.
What is the area of triangle B?
A.
112 cm2
B.
18 cm2
C.
12 cm2
D.
27 cm2
Answer:
Area of triangle B is 112 cm²
Option A is correct option.
Step-by-step explanation:
The dimensions of triangle B are twice the dimensions of triangle A.
Area of triangle A = 28 cm²
We need to find area of triangle B
We know that if base = b and height = h for triangle A
The area of triangle A will be: [tex]Area_A=\frac{1}{2}\times b \times h[/tex]
The dimensions for triangle B will be:
[tex]h_B = 2 h_A\\b_B = 2 b_A[/tex]
Putting in formula we get:
[tex]Area_B=\frac{1}{2}\times b\times h \\Area_B=\frac{1}{2}\times (2b)\times 2(h)\\Area_B=4( \frac{1}{2}\times b\times h)\\Area_B=4(Area_A)[/tex]
SO, we get [tex]Area_B=4(Area_A)\\[/tex]
We have Area_A = 28 cm²
Area of triangle B Area _B is:
[tex]Area_B=4(28)\\Area_B=112\:cm^2[/tex]
So, Area of triangle B is 112 cm²
Option A is correct option.

The school library has 36 shelves of books . Each shelf can hold 42 books . How many books can the shelves in the library all together ?
Answer:1,512
Step-by-step explanation:
Since they are asking for the total number of books you multiply the number of shelves by the number of books each shelf can hold. 36x42
The total number of books in the library is A = 1512 books
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the total number of books in shelve = 42 books
Total number of books = Number of shelves x Number of books per shelf
Total number of books = 36 x 42
Total number of books = 1,512
Hence , the shelves in the library can hold 1,512 books all together.

Grant bought strawberries and bananas from the grocery store to make smoothies. The total amount he spent can be represented by the expression 1.8s + 0.65b, where s is the number of pounds of strawberries and b is the number of pounds bananas. If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas, how much did he spend? Amount spent can be represented by the exper
Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)
= 4.86 + 0.91
= $5.77
He spent $5.77 on both items

Michelle‘s father bought him a 16 foot board to cut into shelves for his bedroom Michelle plans to cut the board into 11 equals Size links for his shows the saw blade that Michelle will use to cut the board will change the length of the board by -0.125 inches for each cut How old is affect the total length of the board
Answer:
Step-by-step explanation:
Given that :
Length of board = 16 feet
Converting length of Board to inches:
1 foot = 12 inches
Total initial length in inches = (16 * 12) = 192 inches
To cut in 11 equal pieces : blade will have to be used 10 times
Since the Blade changes the length of each. Piece by - 0.125 inches
The total change or reduction in inch:
-0. 125 inches * 10 pieces = - 1.250 inches
Hence the total change in length :
Initial length - total reduction ;
192 inches - 1.250 inches
192 - 1.250 = 190.750
Therefore, size of each shelf will be:
190.750 / 11
= 17.34

If f(x) = 3x + 2, what is f(5)?
Answer:
17
Step-by-step explanation:
f(x) is the same as y=. "What is f(5)" is the same as saying what is y=3x + 2 when x is 5.
Either way, you are going to replace x with is numerical value, which is 5, and then solve.
y = 3(5) + 2
y = 15 +2
y = 17
f(5) = 17

Answer:
- 2 ft/ s
Step-by-step explanation:
The rate of change is the slope m of the line.
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 80) and (x₂, y₂ ) = (40, 0) ← 2 points on the line
m = [tex]\frac{0-80}{40-0}[/tex] = [tex]\frac{-80}{40}[/tex] = - 2

1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent
3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.
Answer:
Step-by-step explanation:
1). Slope of a line shown on the graph will be,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{1}[/tex]
= -4
2). Slope of the given horizontal line can be determined by,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Since, rise of the given line is zero.
Therefore, slope of the given horizontal line will be 0.
3). Slope of the line passing through the indicated line = -2
Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).
Answer:
Step-by-step explanation:
1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.
2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.
