Answer:
122
Step-by-step explanation:
Use the formula P=2(l+W)
the length would be 65ft and the perimeter would be 374
can anything be simplified 7x - 11x
yes 7 - 11 = -4
so 7x - 11x = -4x
Anyone know? Someone said 120 but that’s obviously not an option!

For what value of p are 2p + 1, 13, 5p – 3, three consecutive terms of AP?
Answer:
4
Step-by-step explanation:
The arithmetic progression terms, are
(2p+1), 13, (5p-3).
First find the distance between 2p+1 and 13.
[tex]13 -( 2p + 1 )= - 2p + 12[/tex]
Then find distance between 13, and 5p-3
[tex]5p - 3 - ( 13) = 5p - 16[/tex]
Terms in a AP progression should have same distances as each other.
[tex]5p - 16 = - 2p + 12[/tex]
[tex]7p = 28[/tex]
[tex]p = 4[/tex]
Answer:
Given 2p+1, 13 , 5p-3 are in AP. P is 4.
John is trying to graph the inequality x < or = to 10. Should John draw an open or closed circle when graphing this inequality? Explain your reasoning.
John should use the closed circle when representing the inequality x ≤ 10.
What is an inequality?An inequality is an expression that shows the relationship between two or more numbers and variables.
Given the inequality x ≤ 10. To graph this inequality, we need to represent it on a number line.
When representing on a number line, closed circle is used to represent ≤ or ≥ while open circle represents < or >.
John should use the closed circle when representing the inequality x ≤ 10.

Consider all six-digit numbers that can be created from the digits 0-9 where the first and last digits must be odd and no digit can repeat. What is the probability of choosing a random number that starts with 9 from this group? Enter a fraction or round your answer to 4 decimal places, if necessary
Using the Fundamental Counting Theorem, it is found that there is a 0.2 = 20% probability of choosing a random number that starts with 9 from this group.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, we have that:
The first and last digit have to be odd, hence [tex]n_1 = 5, n_6 = 4[/tex].The others cannot repeat, hence: [tex]n_2 = 8, n_3 = 7, n_4 = 6, n_5 = 5[/tex].Then, the total number is:
N = 5 x 4 x 8 x 7 x 6 x 5 = 33600.
Starting with 9, we have that:
The first digit is 9, the last digit has to be an odd which is not 9, hence [tex]n_1 = 1, n_6 = 4[/tex].The others cannot repeat, hence: [tex]n_2 = 8, n_3 = 7, n_4 = 6, n_5 = 5[/tex].Then:
N9 = 1 x 4 x 8 x 7 x 6 x 5 = 6720.
A probability is given by the number of desired outcomes divided by the number of total outcomes, hence:
p = N9/N = 6720/33600 = 0.2.
0.2 = 20% probability of choosing a random number that starts with 9 from this group.

One angle of an isosceles triangle measures 124 degrees. What measures are possible for the other
two angles? Choose all that apply.
44
81°
11°
28°
Answer:
28°
Step-by-step explanation:
In an isosceles triangle, by definition two of the three sides of the triangle are equal to one another. Therefore, the angles opposite to these sides must also be equal. And considering the Triangle Sum Theorem, the angles of a triangle must add up to 180 degrees, the angle that measures 124 degrees cannot be be equal to another angle due to the fact that the sum of them would exceed 180. Therefore let x be the angle:
124+2x=180
2x=56x=28°

Two runners start the race at the same time. The first runner's speed is 4/5 of the speed of the second runner. After 30 minutes, the runners are 2 miles apart. What is the speed of each runner?
*not 1.78 & 2.22 :(*
Using proportions, it is found that the speed of the runners are of 16 mph and of 20 mph.
What is a proportion?A proportion is a fraction of a total amount.
After 30 minutes, the runners are 2 miles apart, hence the second runner is 4 miles per hour faster than the second, that is:
[tex]v_2 = v_1 + 4[/tex].
The first runner's speed is 4/5 of the speed of the second runner, hence:
[tex]v_1 = \frac{4}{5}v_2[/tex]
[tex]v_1 = \frac{4}{5}(v_1 + 4)[/tex]
[tex]\frac{1}{5}v_1 = \frac{16}{5}[/tex]
[tex]v_1 = 16[/tex]
[tex]v_2 = 16 + 4 = 20[/tex]
Hence, the speed of the runners are of 16 mph and of 20 mph.

Find the values of x and y.
Step-by-step explanation:
The figure shows an isosceles triangle. The two sides of an isosceles triangle are equal and the two base angles are equal. Since line AD is the angular bisector of the top Angle of an isosceles triangle, AD is also the base midline and base perpendicular bisector of the triangle.
So x=90 degrees.
The angles of a triangle add up to 180 degrees. So ∠DAC=(180-90-47)=43 degrees
y=43 degrees.
Answer:
y = 43°
x = 90°
Step-by-step explanation:
x = 90°(right angle)
y + 47 + x = 180(base angles of isosceles are equal)(all angles of triangle are equal)
y + 47 + 90 = 180
y + 137 = 180
y = 180 - 137
y = 43°

Identify the solution to the following inequality: -1/2 (x+3) > x - 3
A. X < 1
B. X > 3
C. X > 1
D. X< 3
Answer:
A
Step-by-step explanation:
- [tex]\frac{1}{2}[/tex] (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )
- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1
- x - 3 > 2x - 6 ( subtract 2x from both sides )
- 3x - 3 > - 6 ( add 3 to both sides )
- 3x > - 3
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity
x < 1
Answer:
A. x<1
Step-by-step explanation:
-1/2 (x+3) > x - 3
(-1/2)x-3/2>x-3
Multiply both sides by 2:
-x-3>2x-6
add both sides by 3:
-x-3+3>2x-6+3
-x>2x-3
minus both sides by 2x
-x-2x>2x-2x-3
-3x>-3
x<1
