Which are vertical angles?
Step-by-step explanation:
AFE-BFD<---------------
Hello.
Vertical angles are two sets of angles congruent to each other, both on opposite sides, but measure the same.
In the diagram shown, both angles ∠BFC and ∠EFA are identical, it seems mirrored, thus they are vertical angles.
The correct answer is B.

Answer:
P = 2( l + b )
=>130 = 2 (l + 30)
=>130 = 2l + 2*60
=> 130 = 2l + 60
=> 130 - 60 = 2l
=> 70 = 2l
=> 70/2 = l
=> 35 = l
Length = 35cm
Area = l * b
=> A = 35 * 30
=> A = 1050
Therefore area = 1050[tex]cm^{2}[/tex]
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Answer:
l=35 and A=1050
Step-by-step explanation:
the formula of rectangle to calculation perimeter is p=2(l+b)
130/2=l+b
l=35 and
A=l*b
a= 35*30=1050

Answer:
7.92
Step-by-step explanation:
Given
c² + 0.1c - 24 ← substitute c = - 5.7 into the expression
= (- 5.7)² + 0.1(- 5.7) - 24
= 32.49 - 0.57 - 24
= 31.92 - 24
= 7.92

She applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space, c, m, end text, cubed of mulch for every m 2 m 2 start text, space, m, end text, squared of garden space. At what rate is Riya applying mulch in m 3 m 2 m 2 m 3 start fraction, start text, m, end text, cubed, divided by, start text, m, end text, squared, end fraction?
Answer:
0.25m³
Step-by-step explanation:
If Riya is applying mulch to her garden. She applies it at a rate of 250,000 cm³ for every m², to know how much she is applying in m³ for every m², we will make use of the conversion formula:
100cm = 1m
1cm = 1/100m
1cm = 0.01m
250,000cm³ = 250,000 × 1cm×1cm×1cm
250,000cm³ = 250,000×0.01×0.01×0.01
= 250,000×0.000001
= 0.25m³
Hence Riya is applying at 0.25m³ per m²
Answer:
0.25m³ / m²
Step-by-step explanation:
Given that:
Rate of application = 250,000 cm³ of mulch per m²
The rate of application in m³ per m² can be calculated thus :
Converting 250,000 cm³ to m³
1cm = 1/100 = 0.01m = 1 * 10^-2 m
Hence
1cm³ = (1 * 10^-2 m)³ = 1 × 10^-6 m³
Hence,
250,000cm³ = (250,000 * 10^-6)m³ = 0.25m³
Hence, rate of application in m³ / m² equals
0.25m³ / m²
Solve the equation. If the equation is an identity, choose identity. If it has no solution, choose no solution.
−12x+1=7x−14
Answer: x=15/19 =0.789
Step-by-step explanation: -12*x+1-(7*x-14)=0
-19x+15 = 0
Subtract 15 from both sides of the equation :
-19x = -15
Multiply both sides of the equation by (-1) : 19x = 15
Divide both sides of the equation by 19:
x = 15/19 = 0.789
x = 15/19 = 0.789

Given:
The expression is [tex]\dfrac{7}{\frac{5}{8}}[/tex].
To find:
The shows the correct way to use the rule ""multiply by the reciprocal"" for the given expression.
Solution:
According to the rule "multiply by the reciprocal", if a,b,c,d are four number, then
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
We have,
[tex]\dfrac{7}{\frac{5}{8}}[/tex]
It can be written as
[tex]\dfrac{7}{\frac{5}{8}}=\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}[/tex]
Using the rule "multiply by the reciprocal", we get
[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7}{1}\times \dfrac{8}{5}[/tex]
[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7\times 8}{1\times 5}[/tex]
[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{56}{5}[/tex]
Therefore, the correct option is D.

At this rate,how much would Gianna earn for 8 hours of work? Show work to justify your answer.
At this rate, how long would Gianna have to work to earn $60? Show work to justify your answer.
150 ÷ 20 = 7.5 minutes per 1 mile
7.5 x 6 = 45 minutes
7.5 + 7.5 = 15 minutes or 2 miles in 15
60 ÷ 7.5 = 8 mph
mpm = 7.5
90 ÷ 5 = $18 per hour
18 x 8 = $144
18 x 3 = 54 (close to $60)

what is the missing x for 2x + 65 = 180
Answer:
x=115/2
Step-by-step explanation:
Answer:
x = 57.5
Step-by-step explanation:
Step 1: Write equation
2x + 65 = 180
Step 2: Solve for x
Subtract 65 on both sides: 2x = 115Divide both sides by 2: x = 115/2Divide: x = 57.5Step 3: Check
Plug in x to verify it's a solution.
2(115/2) + 65 = 180
115 + 65 = 180
180 = 180
Which statement describes the transformation that would map figure QRST to figure Q'R'S'T' on the grid above?
(x,y) → (-x,y - 9) is the correct transformation for the given graph so option (A) will be correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the quadrilateral QRST not if we look at Q'R'S'T' it is 9 units downward so it means there will be 9 units decrement in y units.
So y → y - 9
Now,
Q'R'S'T' is as far from the x-axis as QRST but on the negative x-axis.
So,
x → -x
Hence "(x,y) → (-x,y - 9) is the correct transformation for the given graph".

- 10x - y = 27
- 4x - y = 9
Find the solution of the system equation.
Step-by-step explanation:
-10x - y = 27 ...1
-4x - y = 9 ...2
...1 - ...2
-10x -y - (-4x - y) = 27 - 9
-10x -y +4x + y = 18
-10x + 4x = 18
-6x = 18
x = 18/(-6)
= -3
Answer:
x = - 3, y = 3
Step-by-step explanation:
Given the 2 equations
- 10x - y = 27 → (1)
- 4x - y = 9 → (2)
Multiplying (1) by - 1 and adding to (2) eliminates the term in y
10x + y = - 27 → (3)
Add (2) and (3) term by term to eliminate y
6x = - 18 ( divide both sides by 6 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (2)
- 4(- 3) - y = 9
12 - y = 9 ( subtract 12 from both sides )
- y = - 3 ( multiply both sides by - 1 )
y = 3
Solution is x = - 3, y = 3

Step-by-step explanation:
Robert earned $10, which was 4 less than twice what Eric earned. How much money
did Eric earn?
In a complete sentence, state the correct equation for the scenario.
Identify and define your variable. Then, using the correct vocabulary, and math
process, explain how to accurately solve the problem. Lastly, In a complete sentence
define your answer.
Answer:
Eric earnings equals $7
Step-by-step explanation:
Let amount earned by Robert = $10
Amount earned by Eric = $x
Robert earnings = 2x - 4
2x - 4 = 10
2x = 10 + 4
2x = 14
Divide both sides by 2
x = 14 / 2
= 7
x = 7
Eric earns $x which is equal to $7
Eric earnings equals $7
