Answer: 4). 35,56,89
Step-by-step explanation: for a triangle to be acute all three angles have to measure below 90 degrees
Answer:
your answer would be 4 or D
Step-by-step explanation:
a acute angle is and angle from 30-89
a 90 degree angle is just 90 degrees
and an obtuse angle is 91-130
so therefore you have your answer
D or 4

Describe the lines below as parallel,
perpendicular, or neither.
2x - 5y = 25 and y= 5x+3
Answer:
Neither.
Step-by-step explanation:
First, we write 2x - 5y = 25 in slope-intercept form. That gets us y = 2/5x - 5. Now, we graph both the lines (check the image attached). Parallel means extending in the same direction, everywhere equidistant. Perpendicular means the relationship between two lines that meet at a right angle (90 degrees). As we can see in the screenshot, these lines don't fit any of these categories, so we put "neither."
The lines 2x - 5y = 25 and y = 5x + 3 are neither parallel nor perpendicular
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Equations of two lines are given, They are 2x - 5y = 25 and y = 5x + 3.
Now, Writing them in slope-intercept form,
2x - 5y = 25.
- 5y = - 2x + 25.
y = (2/5)x - 5.
And,
y = 5x + 3.
Now, We know lines parallel to each other have the same slope, and lines perpendicular to each other have a slope that is negative reciprocal of each other.
Therefore the lines y = (2/5)x - 5 and y = 5x + 3 are neither parallel nor perpendicular.

Ehich of thr following expressions has a Simplified value of 3A -2?
A carpenter is making a wooden window frame that has a width of 1 inch. How much wood does the carpenter need to build the frame? 5.5 + 106 square inches 5.5 + 116 square inches 5.5 + 153 square inches 5.5 + 162 square inches
Diagram attached
Answer:
5.5+106 square inches
Step-by-step explanation:
The wooden frame has different shapes- semi circle, rectangles and we would have to calculate area of all the shapes to get the wood required.
To get area of the circle, we use the formula π(R²-r²)/2. Subtract the inner radius from the outer radius =
π(6²-5²)/2= 11π/2
=5.5π square inches
We add area of the semi circle to area of the 3 rectangles from the diagram:
2×1×48×10×1=106 square inches
The rectangle with 10 inches is because we subtracted one inch from both sides of the 12 inches rectangle to avoid repetition and overvaluing the area
Total area =5.5π +106 square inches
Options must have ommitted the "π"
Answer:
5.5 + 106 square inches

Answer:
[tex]y = 8x[/tex]
Step-by-step explanation:
Find slope by using Rise/Run.
Use two coordinate points that are part of the graph.
(0,0) and (2,16)
[tex]m = \frac{16 - 0}{2 - 0} \\ m = \frac{16}{2} \\ m = 8[/tex]
We have the slope. We need to find the y-intercept.
From the graph, the graph passes y-axis (0,0). Therefore the y-intercept is at (0,0)
[tex]y = mx + b[/tex]
[tex]m = 8 \\ b = 0[/tex]
Substitute m = 8 and b = 0 in the equation.
[tex]y = 8x + 0 \\ y = 8x[/tex]

what the value of -1/4[12x-0.2(12x + 8x]
Answer:
-2x
Step-by-step explanation:
cos sec² a - cot²a=1
Answer:
The relation is:
cosec^2(a) - cot^2(a) = 1.
Where:
cosec(x) = 1/sin(x)
cot(x) = 1/tan(x) = cos(x)/sin(x)
Let's prove this.
Ok, we know by the Pythagorean theorem, that:
r^2 = x^2 + y^2
And we have the trigonometric relations, for an angle "a" measured from the x-axis
cos(a) = x/r
sin(a) = y/r
tan(a) = y/x
Where r is the hypotenuse, x and y are the catheti.
Now, let's divide the Pythagorean theorem by y^2 in both sides to get:
(r^2/y^2) = (x^2 + y^2)/y^2
r^2/x^2 = x^2/y^2 + y^2/y^2
r^2/y^2 = 1 + x^2/y^2
(r/y)^2 = 1 + (x/y)^2
and remember that:
y/r = sin(a)
then:
r/y = 1/sin(a) = cosec(a)
(r/y)^2 = cosec^2(a)
and:
y/x = tan(a)
then:
x/y = 1/tan(a) = cot(a)
and:
(x/y)^2 = cot^2(a)
replacing these in the equation (r/y)^2 = 1 + (x/y)^2 we get:
cosec^2(a) = 1 + cot^2(a)
cosec^2(a) - cot^2(a) = 1

how many heavier is 9 pounds 20 ounces than 160 ounces (1 pound = 16 ounces)
1 pound = 16 ounces.
9 pounds 20 ounces =
9 x 16 = 144
144 + 20 = 164
164-160 = 4
9 pounds 20 ounces is 4 ounces heavier than 160 ounces.
Answer:
1 pound = 16 ounces
9 pounds 20 ounces =(9×16)+20= 144+20 =164 ounces
(164-160) ounces
9 pound 20 ounces is 4 ounces heavier than 160 ounces
4 ounce is the right answer.Write an equation for the line in slope-intercept

The number of students participating in this year's fundraiser is 6 more than
times the
number of students who participated last year. If x represents the number of students who
participated last year, which expression represents the number of students participating in
this year's fundraiser?
Answer:Simplifying
(5x + -6)(5x + -3) = 0
Reorder the terms:
(-6 + 5x)(5x + -3) = 0
Reorder the terms:
(-6 + 5x)(-3 + 5x) = 0
Multiply (-6 + 5x) * (-3 + 5x)
(-6(-3 + 5x) + 5x * (-3 + 5x)) = 0
((-3 * -6 + 5x * -6) + 5x * (-3 + 5x)) = 0
((18 + -30x) + 5x * (-3 + 5x)) = 0
(18 + -30x + (-3 * 5x + 5x * 5x)) = 0
(18 + -30x + (-15x + 25x2)) = 0
Combine like terms: -30x + -15x = -45x
(18 + -45x + 25x2) = 0
Solving
18 + -45x + 25x2 = 0
Solving for variable 'x'.
Factor a trinomial.
(3 + -5x)(6 + -5x) = 0
Subproblem 1
Set the factor '(3 + -5x)' equal to zero and attempt to solve:
Simplifying
3 + -5x = 0
Solving
3 + -5x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -5x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -5x = 0 + -3
-5x = 0 + -3
Combine like terms: 0 + -3 = -3
-5x = -3
Divide each side by '-5'.
x = 0.6
Simplifying
x = 0.6
Subproblem 2
Set the factor '(6 + -5x)' equal to zero and attempt to solve:
Simplifying
6 + -5x = 0
Solving
6 + -5x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + -5x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + -5x = 0 + -6
-5x = 0 + -6
Combine like terms: 0 + -6 = -6
-5x = -6
Divide each side by '-5'.
x = 1.2
Simplifying
x = 1.2
Solution
x = {0.6, 1.2}

Jeffrey is making cookies to sell at the school fair. For one dozen cookies, he needs 2 ¼ cups of flour. if he has 33 ¾ cups of flour, how many dozen cookies can he make? How many total cookies can he make?
Please help me with this math problem
Answer
Pretty sure he can make 15 dozens. Which means he can make 180 cookies.
Step-by-step explanation:
First, you would need to find how many times 2 1/4 cups can go into 33 3/4 cups. This would let you know how many dozens he can make. You would get an answer of 15 dozens. Then, you would multiply 15 times 12. You would multiply by 12 because a dozen is 12. You would then get an answer of 180. This means that he can make 180 cookies.

A chess club with 80 members is electing a new president. Hans received 32 votes. What percentage of the members voted for Hans?
Answer: 40%
Step-by-step explanation: To find what percentage of members voted for Hans simply multiply 32 by 100.
32 x 100 = 3200.
Then, divide that number, or 3200 by 80.
3200/80 = 40.
So, 40, or 40% of members voted for Hans.:)
