subtract 8 on both sides :
4a=16
divide by 4 on both sides :
a=4
So the value of a is 4hope helpful ~
Answer:
a=4
Step-by-step explanation:
4(2+a)=24
8+4a=24
4a=24-8
a=16/4
a=4

Is it possible for these two triangles to be similar? Why or why not?
Answer:
Angle C= 79 degrees
Angle X= 62 degrees
Yes, the two triangles are similar because all the angles are congruent. The requirement for two triangles to be similar is if two corresponding angles are equal.
Step-by-step explanation:
A triangle is 180 degrees.
So adding the angles of triangle ABC, 62+39=101
180-101=79, so angle c is 79 degrees
Adding the angles of triangle XYZ, 39+79=118
180-118=62, so angle x is 62 degrees
Answer:
Angle C= 79 degrees
Angle X= 62 degrees

Answer:
6: We already know the diamer, which is 18, and the radius which is half of 18. So 18 gets multiplied by PI (In this case 3.14) 3.14*18=56.52, or 56.5. Then we divide it by 2 (Cause it's a half circle.) which is 28.25.
7: 20*3.14=62.8/2=31.4
8: 8*3.14=25.12/2=12.56
(Because this time we didn't know the diameter, but 4+4=8.)

. A pedestal is built using a trapezoid-shaped base. Find the area of the trapezoid.
(1 point)
A equals 18 meters squared
A equals 24 meters squared
A equals 15 meters squared
A equals 22 meters squared
18m^2
area of a trapezoid = (a+b)/2 * h, where a and b are bases 1 and 2, and h is height
(4+8)/2 * 3
= 12/2 * 3
= 6 * 3
= 18
Which system of equations would have no solution? pls helpp
Answer:
3x+y=8 and 3x+y=9
Step-by-step explanation:
Assume these two equations:
a1x+b1y+c1=0
a2x+b2y+c2=0
If (a1/a2) = (b1/b2) ≠ (c1/c2) than those two would have no solution.
In these case, take a look at the last option:
[tex]3x + y = 8 \\ 3x + y = 9[/tex]
Re-write 'em as a standard form:
[tex]3x + y - 8 = 0 \\ 3x + y - 9 = 0[/tex]
So (a1/a2) = (b1/b2) ≠ (c1/c2) is true here:
[tex] \frac{3}{3} = \frac{1}{1} ≠ \frac{ - 8}{ - 9} [/tex]
And they do not have any collision point

The line plot below shows the heights of flowers grown by the students in one of the fifth grade classes. Persia makes a flower arrangement using the 8 longest flowers.
Which is the combined height of the flowers Persia uses?
A. 59 3/4 inches
B. 61 1/2 inches
C. 62 1/4 inches
D. 63 1/4 inches
The combined height of the flowers Persia uses will be 61 1/4 inches. Then the correct option is C.
How does the dot plot work?Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.
The line plot below shows the heights of flowers grown by the students in one of the fifth-grade classes. Persia makes a flower arrangement using the 8 longest flowers.
Then the combined height of the flowers Persia uses will be
→ 6.5 + 6.75 + 7 + 7.25 + 7.5 + 7.75 + 8.5 + 10
→ 61.25
The number 61.25 can be written as
→ 61 and 1/4 inches

A spinner is divided into 11 equal sections numbered from 0 to 10. You spin the spinner once. What is P(even)
Answer:
[tex]p(even)= \frac{6}{11}[/tex]
Step-by-step explanation:
It's given in the question that;
The spinner is divided into 11 equal sections from 0 to 10.
You spin the spinner ONCE!
The total number of possibilities is six, and the total number of sample spaces is 11.
So the probability of getting an even number is; [tex]p(even)= \frac{6}{11}[/tex]

An inspector at a shirt factory randomly selects shirts to inspect for defects. The table below shows the number of shirts she found with defects last week.
Based on this information, which of these is the best estimate of the probability that the next shirt she inspects will have a defect?
PLEASE HELP GIVING ALL MY POINTS AND BRAINLIST
A.
10%
B.
11%
C.
12%
D.
22%
Answer:
The answer is B
Step-by-step explanation:
find the average of how many she inspected every day:
(30+35+40+45+50) / 5 = 40
(6+4+4+5+3) / 5 = 4.4
so on average, she inspected 40 shirts a day and found (technically) 4.4 defects
so to find the percentage we do this:
4.4/40 * 100 = 11%
so the answer is B

give the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet, calculate the radius (R) of the pole that will produce a perfect lawn
Answer:
The radius is 0.398 feet to produce a perfect lawn for the lawnmower.
It is given that the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet.
It is required to calculate the radius (R) of the pole that will produce a perfect lawn.
What is a circle?
It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have,
Width of the lawnmower = 2.5 feet
Length of the rope = 25 feet
For the perfectly mowed lawn, it means the lawnmower width which is 2.5 feet must wrap the pole with radius R, mathematically:
The perimeter of the pole = width of the lawnmower
2πR = 2.5
R = 0.398 Feet ( π = 3.14 )
Thus, the radius is 0.398 feet to produce a perfect lawn for the lawnmower.

Math Question In image.Please help me. Due Today
Answer:
See below
Step-by-step explanation:
If the diameter is doubled, the circumference is doubled. It is shown here:
18 * 3.14 = 56.52
36 (doubled diameter) * 3.14 = 113.04
If the circumference with the doubled diameter divided by the circumference of the original diameter comes out as 2, then it is proven that doubling the diameter doubles the circumference.
113.04/56.52 = 2.
The image for the rest is attached.
Answer:
Step-by-step explanation:
The Radius is (1/2) of the diameter, so to get the diameter we will multiply the radius by 2.
1. 9*2=18in
The we multiply the diameter by [tex]\pi[/tex] to get the cicumference. We know to do this because the equation of the circumference is C=[tex]\pi[/tex]d or C=2[tex]\pi[/tex]r. (p.s [tex]\pi[/tex]=3.1415926)
2. 18in*(3.1415926)=56.5487in
3. If the diameter is doubled the circumference is also doubled. We know this because of the equation C=[tex]\pi[/tex]d. The circumference is dependant upon the diameter and grows (or shrinks) with it.

A rabbit's fur grows at the rate of 5 over 2 inches per month.
How many months will it take the rabbit's fur to grow 15 over 4 inches?
Explain your answer using expressions and words.
Growth rate = 5/2 inches per month
The fur length after y months:
Fur length = 5/2 × y
Therefore, to have a fur length of 15/4 inches :
15/4 = 5/2 × y
3.75 = 2.5y
Divide both sides by 2.5 to isolate y
3.75/2.5 = y
1.5 = y
it will take a month and half to have a fur of 15/4 inch length
Answer:
1.5 months
Step-by-step explanation:
First, make [tex]\frac{5}{2}[/tex] so it has a common demoninator as [tex]\frac{15}{4}[/tex].
We need the demoninator to be the same so we can multiply [tex]\frac{5}{2}[/tex] by 2 to make it [tex]\frac{10}{4}[/tex].
So, a rabbit's ear grows [tex]\frac{10}{4}[/tex] of an inch in a month.
To find how many months, it will take, we have to divide [tex]\frac{15}{4}[/tex] by [tex]\frac{10}{4}[/tex].
To divide fractions, we can multiply with the reciprocal.
So, [tex]\frac{15}{4}[/tex] * [tex]\frac{4}{10}[/tex] is [tex]\frac{60}{40}[/tex] which reduces to [tex]\frac{6}{4}[/tex] which, in decimal form is equal to 1.5 months.
