Answer:
isoceles triangle
Step-by-step explanation:
here two angles of a triangle are 48 degree whereas we know that a triangle having two angles equal is an isoceles triangle ,thus it is isoceles triangle
The perimeter of the triangle is 29 cm.
a. Write an equation and solve for x.
b. Use the value of x to find the lengths of the sides of the triangle.
c. What kind of triangle is this: scalene, isosceles, or equilateral? Explain how you know using the calculated side lengths, not the picture
2x+2
3x - 1
x + 4
Answer:
Step-by-step explanation:
Equation
2x + 2 + 3x - 1 + x +4 = 29 Collect like terms on the left
6x + 5 = 29 Subtract 5 from both sides
6x = 29 - 5
6x = 24 Divide by 6
x = 24/6
x = 4
Length of the Sides.
2x + 2 = 2*4+2 = 10
3x - 1 = 3*4 - 1 = 12 - 1 = 11
x + 4 = 4 + 4 = 8
Type of Triangle
Scalene.

1 triangle: 2 m²2 triangles: 4 m²large rectangle: 32 m²small rectangle: 3 m²total area: 39 m²cost of tile: $487.50Step-by-step explanation:
You will run across many examples of poorly edited curriculum materials. This is one of them. We presume that every instance of "inches" should be an instance of "meters". The difference between in and m is not always obvious in a diagram, and m apparently got misinterpreted here.
__
The area of a triangle is given by the formula ...
A = 1/2bh
where b is the base and h is the height perpendicular to the base.
The triangles in this figure have a base of 4 m, and a height of 1 m. Using this formula, we find the area of 1 triangle to be ...
A = 1/2(4 m)(1 m) = 2 square meters . . . . area of 1 triangle
__
The triangles are the same size, so the area of both together is ...
2(2 m²) = 4 square meters . . . . area of both triangles together
__
The large rectangle is 8 m long and 4 m high. Its area is given by the formula ...
A = LW
where the length is L and the width is W. Using this formula, we find the area of the large rectangle to be ...
A = (8 m)(4 m) = 32 m² . . . . area of large rectangle
__
The small rectangle has a length of 3 m and a width of 1 m. Its area is ...
A = (3 m)(1 m) = 3 m² . . . . area of small rectangle
__
The total area is the sum of the areas of the pieces:
total area = 2 triangles + large rectangle + small rectangle
total area = 4 m² + 32 m² + 3 m² = 39 square meters
_____
At $12.50 per square meter, the cost of covering the patio is ...

Two Quadratic functions are represented below
f(x)=-x^2+4x-3
a. In two or more complete sentences, explain how you can determine the maximum value of the
quadratic functions, f(x) and g(x).
b. Which function has the greater maximum value, f(x) or g(x)?
You can tell that the maximum value that [tex]g[/tex] attains is roughly [tex]4[/tex].
Rewriting [tex]f[/tex] in vertex form: [tex]f(x)=-(x-2)^2+1[/tex]. This tells us that the maximum of [tex]f[/tex] is [tex]1[/tex].
So [tex]g[/tex] has the greater maximum.
Answer:
g(X)

A camper is flying a kite at the end of a string 250 feet long. If they look up to
the kite at an angle of 43 degrees, what is the approximate height of the kite? (Round
your answer to the nearest foot.).
hypotenuse is 250 feet.
base angle is 43 degrees.
trignometery here I come!
Since we must find the height, aka adjacent side of right triangle, and we have the given hypotenuse
We shall use the sine!
sinθ is sin43
sin43 = A/H = x/250
multiply both sides by 250
250 (sin43) = x

Erin wants to know if warming up will help runners sprint faster. Twenty-six track and field athletes volunteered to participate in her study. She randomly assigns 13 athletes to warm-up for 10 minutes. All 26 participants sprint the same distance. She calculates the mean for each group and determines that the mean for the warm-up group was 10.9 seconds, and the mean for the other group was 12.9 seconds. To test the difference of means she re-randomized the data 54 times, and the differences are plotted in the dot plot below. What can Erin conclude from her study? (6 points) A dot plot is shown labeled from negative 2.5 to positive 2. Above the negative 2.5 are 3 dots. Above the negative 2 are 6 dots. Above the negative 1.5 are 9 dots. Above the negative 1 are 12 dots. Above the negative 0.5 are 6 dots. Above the 0.0 are The difference in the means is not significant because a difference of 2 is not very likely. The difference in the means is not significant because a difference of 2 is very likely. The difference in the means is significant because a difference of 2 is very likely. The difference in the means is significant because a difference of 2 is not very likely.

A ticket broker is selling seats to a rock concert. If the broker's commission is a $5.00 base fee and $0.50 extra for every ticket (t), the total cost for the broker's services is calculated by the expression below.
$0.50t + $5.00
How much does the broker earn by selling 12 tickets?
$5.50
$10.50
$11.00
$15.50
Answer:
11.00
Step-by-step explanation:
"T" is the number of tickets sold so take 0.50*12 and you would get 6.00
then take 6+5=11, then 11 is the answer

Here is a graph of the relationship between the height and volume of some cylinders that all have the same radius, R. An equation that represents this relationship is V =Rºh (use 3.14.as an approximation for 7). What is the radius of these cylinders?
Answer:
Radius is 1 unitStep-by-step explanation:
The relationship is:
V = πr²hWe have points on the graph:
(9, 28.26) and (18, 56.52)Use one of the points, substitute into equation and solve for r:
28.26 = 3.14*9*r²r² = 28.26/28.26r² = 1r = 1During the 2 9-weeks reporting, a student's grade increased from 80 to 96. By what percentage did the grade increase?

2x[tex]2x^{2}-3x-5[/tex]
Answer:
2x²-3x-5
=2x²-3x-5
=2x²-5x+2x-5
=2x(x-5)+2(x-5)
=(x-5)(2x+2)
Answer:
(x + 1)(2x - 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2x² - 3x - 5
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 5 = - 10 and sum = - 3
The factors are + 2 and - 5
Use these factors to split the x- term
2x² + 2x - 5x - 5 ( factor the first/second and third/fourth terms )
= 2x(x + 1) - 5(x + 1) ← factor out (x + 1) from each term
= (x + 1)(2x - 5) ← in factored form

Answer:
I) 616
II) 4.53
Step-by-step explanation:
For the first one, just plug in 7 as R.
A = 4 x (22/7) x 7^2
A = 12.57142857 x 49
A = 616
For the second, one, put 452 4/7 as A.
452 4/7 also is 258.285
258.285 = 4 x (22/7) x r^2
258.285 = 12.57142857 x r^2
Divide both sides by 12.57142857
20.55372408 = r^2
Square root 20.55372408 for R.
4.533621519 = R
OR
4.53 = R

Answer:
See the explanation
Step-by-step explanation:
Given data
Although we are not given any two vital parameters that are needed to find the radius of a circle
The first is the circumference
And the second is the area
To find the radius with a given circumference we use
C=2πr
To find the radius with a given area we use
A=πr^2
Answer:
220 feet and 126 feet are the circumferences of the two circles

If there are 60 seconds in an minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week? Hint: Use a calculator to solve this problem.James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?
Answer:
Part a) 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week
60x60=3600 x 24= 86400 x 7= 604800
So 604,800 seconds in a week
Part b) James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?
So 3 x 1= $3
+ $2
2 x 2= $4
3+2+4= $9
10-9= $1
So they'll get back $1
Question 7 of 12 Solve: 3x- 8 = 6(1 - 2x) + 16 O A. x = 2 O B. x = 5 O C. x= -2 O D. There are infinitely many solutions.
Answer:
A. x =2
Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16
Distribute
Add the numbers
Add 8 to both sides of the equation
Simplify
Add 12x to both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify -------> x=2
