Answer:
Right scalene triangle
Acute equilateral triangle
Step-by-step explanation:
For the first triangle, we will use the Converse of the Pythagorean Theorem:
If c² < a² + b², then it means that it is an acute triangle.
If c² = a² + b², then it means that it is a right triangle.
If c² > a² + b², then it means that it is an obtuse triangle.
For the first triangle, let c = 25 yd, a = 7 yd, and b = 24 yd
c² = a² + b²
25² = 7² + 24²
625 = 49 + 576
625 = 625 (True statement).
Therefore, the first triangle is a right triangle. At the same time, each angle have different measures, making it a scalene triangle. Therefore, the first triangle is an example of a right scalene triangle.
For the second triangle, since all sides are equal, it doesn't matter which side we label as a, b, or c.
Let's see which type of triangle it is according to its sides:
c² = a² + b²
32² = 32² + 32²
1024 < 2048
Therefore, it is an acute triangle. At the same, the second triangle has equal sides, making it an equilateral triangle. Therefore, the second triangle is an example of an acute equilateral triangle.

Step-by-step explanation:
Step-by-step explanation:
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
First row:
Months (input) and Days (output) = not a function. The month of February has two corresponding outputs: Days of 28 and 29.
{(13, 33), (17, 25), (22, 22), (25, 17), (33, 17)} = this relation is a function. Each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).
Plot of Distance (mi) vs. Time (h): the graph represents a function. Each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).
Second row:
{(1, 2), (5, 2), (5, 4), (7, 6), (11, 6), (11, 8)}: this relation is not a function. The input value of 5 has two corresponding output values: 2 and 4. The same goes with the input value of 11, which has two output values of 6 and 8.
Table of Age (x) and Shoe Size (y): does not represent a function. The x = 15 has two corresponding y-values: 10 and 10.5.
Diagram of x and y (bottom-left corner): this relation represents a function. Each input value corresponds to exactly one output value.

Carrie is making a colorful beaded necklace. She has 3 times as many green beads
as red beads, and twice as many blue beads beads. If she has 150 beads
all together, how many of the beads are green?
Answer:
45 green beads
.
Step-by-step explanation:
Let the number of red beads be 'x'
Given that, Carrie has 3 times as many green beads as red beads
Number of green beads = 3 times number of red beads
Number of green beads = 3x
She 2 as many blue beads as green beads
Number of blue beads = 2 times the number of green beads
Number of blue beads = 2(3x) = 6x
She has 150 total
Therefore,
Number of red beads + Number of green beads + Number of blue beads = 150
x + 3x + 6x = 150
10x = 150
x = 15
Thus, number of green beads = 3x = 3(15) = 45
Thus there are 45 green beads
I hope this helps
The question requires finding total green beads she has
There are 45 green beads
let
number of red beads = x
number of green beads = 3x
number of blue beads = 2(3x)
Total beads = 150
Total beads = red beads + green beads + blue beads
150 = x + 3x + 2(3x)
150 = 4x + 6x
150 = 10x
divide both sides by 10
x = 150/10
x = 15
Therefore,
number of red beads = x
= 15 beads
number of green beads = 3x
= 3 × 15
= 45 beads
number of blue beads = 2(3x)
= 2(3 × 15)
= 2(45)
= 90

If f(x) = 2x and g(x) = 5x + 2, what is (f + g)(x) when x = 3?
Answer:
f÷g=2x+5x+2=7x+2
x=3
7×3+2=21+2=23
The value of (f + g)(x) when x = 3, if f(x) = 2x and g(x) = 5x + 2, is 23.
What is function?The function is a relationship between a set of potential outputs and a set of possible inputs, where each input has a single relationship with each output. This means that if an object x is present in the set of inputs (also known as the domain), then a function f will map that object to exactly one object f(x) in the set of potential outputs (called the co-domain).
Given:
f(x) = 2x and g(x) = 5x + 2
Calculate (f + g)(x) as shown below,
f(x) + g(x) = 2x + 5x +2
f(x) + g(x) = 7x + 2
Put x = 3
f(3) + g(3) = 7 × 3 + 2
f(3) + g(3) = 23

Let the distance from A to BC be represented by y, and the distance DE be represented by x. We can write some relations using the definition of the tangent of an angle, and the double-angle formula for tangent. The double-angles are complementary
Left angles
Call the smaller angle α. Then the larger angle is 2α.
tan(α) = x/2
tan(2α) = 2tan(α)/(1 -tan(α)²) = 2(x/2)/(1 -(x/2)²) = 4x/(4 -x²)
Right angles
tan(β) = x/3
tan(2β) = 2tan(β)/(1 -tan(β)²) = 2(x/3)/(1 -(x/3)²) = 6x/(9 -x²)
__
Angles 2α and 2β are complementary, so the product of their tangents is 1.
(4x/(4 -x²))(6x/(9 -x²)) = 1
24x² = (4 -x²)(9 -x²) . . . . multiply by the product of denominators
x⁴ -37x² +36 = 0 . . . . . put in standard form
(x² -36)(x² -1) = 0 . . . . . factor
Solutions to this equation are x = ±1 and x = ±6. Only positive values less than 1.25 can possibly satisfy the geometry. Hence x = DE = 1.
The length of DE is 1.

The normal cruising speed of a certain airplane is about 260 m/sec. What is the speed in miles per hour? Round to the appropriate number of significant digits.
Answer: 582 miles per hour
Step-by-step explanation:
581.603 miles per hour
Round= 582
The speed of an airplane in miles per hour is 581.60 miles/hour.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
Given the speed of an airplane = 260 m/sec
Since,
1 mile = 1.60934 kilometer
1 km = 1000 meter
So,
1 mile = 1609.34 meter
1 m = (1/1609.34) mile
And,
1 hour = 360 seconds
1 s = (1/360)hour
So,
260 m/sec = 260 (3600/1609.34) miles/hour
⇒ 581.60 miles/hour.
Hence "The speed of an airplane in miles per hour is 581.60 miles/hour".

angle W and angle Y are supplementary. If
the measure of angle W = 5x + 20 and the measure of angle Y = 4x - 11, find the measure of angle W
and Y
Answer: angle of w is 115 degrees and angle of y is 65 degrees.
Step-by-step explanation: in the picture.
Answer:
Angle W = 115° Angle Y = 65°angle W and angle y are supplementary
that is angle W + angle Y = 180°
angle w = 5x + 20
angle y = 4x - 11
putting this value in above equation
we get
5x + 20 + 4x - 11 = 180
5x + 4x + 20 - 11 = 180.
9x + 9 = 180
9x = 180 - 9
9x = 171
x = 19
angle W= 5x + 20
= 5(19)+ 20
= 95 + 20
= 115°
angle y = 4x - 11
= 4(19) - 11
= 76 - 11
= 65

Reggie records the lengths of different fabrics he has.
Reggie is left with [tex]\dfrac{27}{8}[/tex] yarns of fabric.
The total length of fabrics = [tex]\dfrac{1}{8}+\dfrac{1}{4}+3\dfrac{1}{2}+2\dfrac{5}{8}+4\dfrac{3}{4}[/tex]
= [tex]\dfrac{1}{8}+\dfrac{1}{4}+\dfrac{7}{2}+\dfrac{21}{8}+\dfrac{19}{4}[/tex]
The LCM of 4 and 8 is 8.
So, the expressions will be simplified by adding all the terms with the same denominator.
= [tex]\dfrac{49}{8}[/tex]
The fabric used by Reggie = [tex]2\dfrac{3}{4}[/tex]
= [tex]\dfrac{11}{4}[/tex]
The fabric left can be calculated by subtracting the total fabric he used from the total fabric he had.
Fabric left =[tex]\dfrac{49}{8} - \dfrac{11}{4}[/tex]
The LCM of 8 and 4 is 8
Fabric left = [tex]\dfrac{49}{8} - \dfrac{22}{8}[/tex]
= [tex]\dfrac{27}{8}[/tex]
So, he is left with [tex]\dfrac{27}{8}[/tex] yarns of fabric.
