Answer:
x > 35
Step-by-step explanation:
The perimeter is twice the sum of length and width. You want x such that ...
P > 156
2(x +(x+8)) > 156
4x +16 > 156 . . . . . simplify
x +4 > 39 . . . . . . . . divide by 4
x > 35 . . . . . . . . . . . subtract 4
The perimeter of the frame will be greater than 156 inches for x > 35.
There are 24 boys and 16 girls in a hall, each holding coins in their hand.The mean number of coins for the children is 11, The mean number of coins for the boys is 9 Work out the mean number of coins for the girls.
Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14
State if the two triangles are congruent. If they are, state how you know.
(look at the picture)
Answer:
Step-by-step explanation:
yes congruent, by AAS
the angles are stating , w/ the little red lines that they are the same.. so we know two angles of the triangles are the same, and we also know that one side touching is the same. so yes.. AAS.
In triangle RST the vertices have coordinates of R(-1,10),S(5,4)and T (-4,-2). If the midpoints of side RS and RT were connected with a segment, what would the slope of this segment be?
Plz helppp
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Midpoint of a line segment joining points [tex](x,y)[/tex] and [tex](u,v)[/tex] is given by [tex](\frac{x+u}{2},\frac{y+v}{2} )[/tex]
Points are R(-1,10),S(5,4)and T (-4,-2).
Midpoint of RS = [tex](\frac{-1+5}{2},\frac{10+4}{2} )=(\frac{4}{2},\frac{14}{2} )=(2,7 )[/tex]
Midpoint of RT = [tex](\frac{-1-4}{2},\frac{10-2}{2} )=(\frac{-5}{2},\frac{8}{2} )=(\frac{-5}{2},4)[/tex]
Slope of a line joining points [tex](a,b)[/tex] and [tex](c,d)[/tex] is given by [tex]\frac{d-b}{c-a}[/tex]
Slope of line joining midpoints of side RS and RT = [tex](\frac{4-7}{\frac{-5}{2}-2 })=(\frac{-3}{\frac{-9}{2} })=\frac{2}{3}[/tex]
Find the class mark of the class 160- 165
Answer:
the classmark of the class is 162.5
Step-by-step explanation:
The computation of the class mark is shown below:
Given that
160 - 165
So, the class mark of the class is
= (Upper limit + lower limit) ÷ 2
= (160 + 165) ÷ 2
= 162.5
Hence, the classmark of the class is 162.5
The helicopter can travel 75 miles per hour. How many miles per minute can the helicopter travel?
Answer:
4.69 miles per minute
Step-by-step explanation:
75 ÷ 60 (60 minutes in an hour) = 4.6875
4.6875 rounded to the nearest hundredth is 4.69

Find the missing length of the right triangle below
Answer:
C = 13
Step-by-step explanation: According to the pythagorean theorem, which states A² + B² = C². This means that in this equation 5²+12²=x². When we solve this we get 169=x². Since 169 is the perfect square of 13 therefore the answer is 13.

What is the mean?
-9 -9 -3 -6 -7
Answer:
-6.8
Step-by-step explanation:
To find the mean, you add all the numbers together, then divide that number by the amount of numbers there were, so:
-9 + -9 + -3 + -6 + -7 = -34
-34/5 = -6.8

Help, The distance between point (2, 2) and point (8, 2) is 6 units on a coordinate plane. Which other pairs of points are also 6 units apart? Select all that apply.
Step-by-step explanation:
Given - The distance between point (2, 2) and point (8, 2) is 6 units on
a coordinate plane.
To find - Which other pairs of points are also 6 units apart?
Proof -
The distance between two points (x₁, y₁), (x₂, y₂) are 6 if and only if either
( x₂ - x₁ = 6 and y₂ = y₁ )or ( x₂ = x₁ and y₂ - y₁ = 6 ).
If either of the conditions is satisfied , then only we can say that the two points has ha distance of 6 units between them.
Now, As given
Let (x₁, y₁) = ( 2, 2) , (x₂, y₂) = (8, 2)
Check whether the conditions are satisfied or not .
Here x₁ = 2 , x₂ = 8, y₁ = 2, y₂ = 2
Now,
x₂ - x₁ = 8 - 2 = 6 , y₂ - y₁ = 2 - 2 = 0
∴ we get
1st condition is satisfied, So the points have a distance of 6 units between them.
Now,
Let us suppose another point (x₁, y₁) = ( 4, 3) , (x₂, y₂) = (3, 3)
Here x₁ = 4 , x₂ = 3, y₁ = 3, y₂ = 3
Now,
x₂ - x₁ = 4 - 3 = 1 , y₂ - y₁ = 3 - 3 = 0
Here neither of the conditions are satisfied.
So the points are not at a distance of 6 units from each other.

What is the equation of the graph below?
А
y = 2(x + 4)2 – 2
B
y = (x – 4)2 – 2
C y = 2(x - 4)2 – 2
D
y = 2(x – 4)2 + 4
Answer:
f(x) = 1(x - 4)^2 - 2
Step-by-step explanation:
Recall that the vertex form of the equation of a parabola is
f(x) = a(x - h)^2 + k, where (h, k) is the vertex and a is a scale factor which stretches or compresses the graph vertically.
Looking carefully at the graph, we see that h must be 4 and k must be -2.
Thus, the equation of this parabola is f(x) = 1(x - 4)^2 - 2 (which matches Answer B)

Problem ID: PRABEE2G
Solve:
14x+y=7
Write your answer in the following format:
with no spaces.
Answer:
x = 7/10; y = 21/5
Step-by-step explanation:
y = 6x
4x + y = 7
Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.
4x + y = 7
4x + 6x = 7
10x = 7
x = 7/10
Now we use the first equation and substitute 7/10 for x and solve for y.
y = 6x
y = 6 * 7/10
y = 42/10
y = 21/5
Answer: x = 7/10; y = 21/5

What would the answer be?
Answer:
11.35%
Step-by-step explanation:
Add all of the numbers together to get the total amount of people who visited.
Add all the numbers in the teen section to find how many teens visited.
If you put teens over whole it will give you the fraction 86/758
If you divide 86 by 758 you will get 0.11345646438 .
Move the decimal two places to the right and round to get the percent 11.35.

use adjacent angles to solve for X
Answer:
69 degrees!
Step-by-step explanation:
Angle MKL = 180 - 146 = 34 (Angles on a straight line add up to 180)
Angle x = 180 - 77- 34 = 69 (Angles in a triangle add up to 180)
Hope this helps! Please mark as brainliest!

does anyone know the answer ??
Answer:
I would assume 13
Step-by-step explanation:
It is an isosceles triangle and all the angles are the same, so I think it should be 13. I may be wrong, it has been a while since I did geometry.
