Design An art class is making a mural for their school which has a triangle drawn in the middle. The
length of the bottom of the triangle is x. Another side is 5 more than three times the length of the
bottom of the triangle. The last side is 3 more than the bottom of the triangle. Write and simplify an
expression for the perimeter of the triangle.
What is the expression for the perimeter of the triangle?
(Simplify your answer.)
Answer:
Expression for perimeter of triangle = 5x+8
Step-by-step explanation:
Given that:
Length of bottom of triangle = b = x
Length of other side = a = 3x + 5
Length of last side = c = x + 3
Perimeter of triangle = a + b + c
Perimeter = (3x+5)+x+(x+3)
Perimeter = 3x+5+x+x+3
Perimeter = 5x + 8
Hence,
Expression for perimeter of triangle = 5x+8

The IRS was interested in the number of individual tax forms prepared by small accounting firms. The IRS randomly sampled 50 public accounting firms with 10 or fewer employees in the Dallas-Fort Worth area. The following frequency table reports the results of the study. Estimate the mean and the standard deviation.

Answer:
44.80
9.27
Step-by-step explanation:
From the data:
Midpoint (x) : __ 25 _ 35 _ 45 _ 55 _ 65
Frequency (f) : _ 1 __ 15 __ 22 _ 8 __ 4
The mean (m):
Σfx / Σf
[(25 * 1) + (35* 15) + (45 * 22) + (55 * 8) + (65 * 4)] / (1 + 15 + 22 + 8 + 4)
= 2240 / 50
= 44.80
Standard deviation :
Sqrt[(Σ(X² * f) / Σf) - m²)]
[(25^2 * 1) + (35^2 * 15) + (45^2 * 22) + (55^2 * 8) + (65^2 * 4)] / (1 + 15 + 22 + 8 + 4)
(104650 / 50) - (44.80²)
1908.51 - 44.80^2
2093 - 2007.04
Sqrt(85.96)
= 9.27

SUPER EASY PLEASE HELP:)
Answer:
Step-by-step explanation:
y = -4/5x + 2
y = 2/3x + 2
2/3x + 2 = -4/5x + 2
10/15x + 12/15x + 2 = 2
22/15x = 0
x = 0
y = 2/3(0) + 2
y = 0 + 2
y = 2

Answer:
12Step-by-step explanation:
x is a midsegment of a given triangle as it connects the midpoints of the two sides.
Midsegment is parallel to the third side and equals to half of its measure:
x = 24/2 = 12need help asap!! !! !!
Answer:
18
Step-by-step explanation:
since U is the midpoint of QT, QT = 2(QU)
similarly, QS = 2 (QR)
because QR is parallel to QS and QU is parallel to QT, triangle QUR is similar to triangle QTS. therefore, the scaling factor between QT/QU and QS/QR is equal to the scaling factor between RU and ST.
therefore,
ST = 2(RU)
36 = 2(RU)
18 =RU

If 6:2=8x then answers are A.2x=14 B.2x=48 c. 6x=10 D. 6x=16
Answer:
16x = 6Step-by-step explanation:
If 6:2=8x then answers are A.2x=14 B.2x=48 c. 6x=10 D. 6x=16
6:2=8x can also be written as 6/2 = 8x/1
Cross multiply
2 * 8x = 6*1
16x = 6
Hence the expression can also be written as 16x = 6

A ball is thrown vertically from the top of a building. The height of the ball after t seconds can be given by the function
Answer:The instantaneous velocity of the ball after 4 seconds is -0.4 m/s
Step-by-step explanation:
Step-by-step explanation:
If f(x) is the function which represents the distance that a particle moves after x seconds, with velocity v and acceleration a, then
v(x) = f'(x) ⇒ first derivative
a(x) = f"(x) ⇒ second derivative
∵ A ball is thrown vertically from the top of a building
∵ The height of the ball after t seconds can be given by the
function s(t)= -0.1(t -2)² + 10
- To find the function of the velocity differentiate s(t)
∵ s(t) = -0.1(t - 2)² + 10
- Solve the bracket
∵ (t - 2)² = t² - 4t + 4
∴ s(t) = -0.1(t² - 4t + 4) + 10
- Multiply the bracket by -0.1
∴ s(t) = -0.1t² + 0.4t - 0.4 + 10
- Add the like terms
∴ s(t) = -0.1 t² + 0.4t + 9.6
Now let us differentiate s(t)
∵ s'(t) = -0.1(2)t + 0.4(1)
∴ s'(t) = -0.2t + 0.4
- s'(t) is the function of velocity after time t seconds
∵ s'(t) = v(t)
∴ v(t) = -0.2t + 0.4
We need to find the instantaneous velocity of the ball after 4 seconds
Substitute t by 4
∴ v(4) = -0.2(4) + 0.4
∴ v(4) = -0.8 + 0.4
∴ v(4) = -0.4
∴ The v is -0.4 m/s ⇒ -ve means the velocity is downward
The instantaneous velocity of the ball after 4 seconds is -0.4 m/s

Write an equation of the line that
passes through (-1,2) with a slope
of 4
Answer:
y = 4x - 6
Step-by-step explanation:
(1, -2) ; Slope (m) = 4
Equation of the line : y - y₁ = m(x - x₁)
y - [-2] = 4(x - 1)
y + 2 = 4x - 4
y = 4x - 4 - 2
y = 4x - 6
describe how to classify a polynomial as a monomial, a binomial , a trinomial, or none of these.
Answer:
A polynomial is an expression, and since mono means 1, monomial has 1 term in the expression, binomial has two, trinomial 3
The answer is:
⇨ belowWork/explanation:
Here's how we classify polynomials based on the number of terms:
monomial - has only one term
binomial - has two terms
trinomial - has three terms
polynomial - has four terms or more
Hence, these are the classifications.a lighthouse is located on an island 200 feet from the shore of the mainland as shown. If x=0.65, what is D?

Answer:
251.222 feets
Step-by-step explanation:
X = 0.65 rad
To degree ;
X = 37.24°
We need to obtain the height :
Using Sine rule :
(37. 24 + y + 90) = 180
y = 52.76
y / sin Y = D / sin D
200/ sin 52.76 = D / Sin 90
251.22231 = D / sin 90
251.22231 * sin 90 = D
Sin 90 = 1
D = 251.222 feets
