In a right triangle one of the acute angles is 1/4 the size of the other acute angle find the measure of the larger angle
Answers
In a right triangle, there are 2 acute angles and 1 right angle.
Let x be the measure of the larger acute angle, using the triangle sum theorem (that states that the sum of the interior angles of a triangle is 180) we have that:
[tex]\begin{gathered} x+\frac{1}{4}x+90=180 \\ \frac{5}{4}x=180-90 \\ \frac{5}{4}x=90 \\ 5x=360 \\ x=\frac{360}{5} \\ x=72 \end{gathered}[/tex]The larger acute angle measures 72°.

describe the translation of the point to its image: (-4,-6) to (-6,-12)
Answers
We want to translate from point (- 4, - 6) to (- 6, - 12)
If we translate a point with coordinates, (x, y) by c units to the left and d units downwards, the new coordinates would be (x - c, y - d)
Looking at the given points,
- 4 - 2 = - 6
- 6 - 6 = - 12
Thus, the point was translated by 2 units to the left and 6 units downwards
3. Shown above is the graph for which of the following equations?
O A. y=-x-3
O B.y=x+3
O C. y=x-3
O D.y=3-x
Answers
Using the equation of slope intercept form, the equation of the given graph is y=x-3.
In the given question we have to find equation of the given graph.
From the given graph the points are (3,0) and (0,-3).
We know the standrd equation of the line is y=mx+c
where m=slope and c=value of y at the y intercept form.
So the value of c= -3
Now finding the value of m.
m={y(2)-y(1)}/{x(2)-x(1)}
From the points, x(1)=3, x(2)=0, y(1)=0, y(2)= -3
Putting the value
m=(-3-0)/(0-3)
m=-3/-3
m=1
Now putting the value of m and c in the equation
y=mx+c
y=1*x+(-3)
y=x-3
Hence, the equation of the given graph is y=x-3.

The snow then began to fall at a constant rate of 2.5 inches per hour.
Assuming no snow was melting, how much snow would Hassan have on his
lawn 5 hours after the snow began to fall? How much snow would Hassan
have on his lawn after t hours of snow falling?
Answers
Hassan will have 14.5 inches of snow on his lawn after 5 hours of snow falling.
How to find amount snow ?Individual ice crystals that make up snow develop while suspended in the atmosphere, typically within clouds, before falling and accumulating on the ground, where they go through additional changes.
It starts out as frozen crystalline water that forms in the atmosphere under favourable conditions, grows to millimetre size, precipitates and builds up on surfaces, then undergoes a metamorphosis in place, and finally melts, slides, or sublimates away.
2 inches of snow on the lawn
Rate of snow falling = 2.5 inches per hour
Snow did not melt
Let y = height of snow on the lawn
Let t = time in hours
y = 2 + 2.5t
To find how much snow is on the lawn after 5 hours of snowing, substitute t = 5 into the found equation and solve for y:
⇒ y = 2 + 2.5(5)
⇒ y = 2 + 12.5
⇒ y = 14.5 inches
Therefore, Hassan will have 14.5 inches of snow on his lawn after 5 hours of snow falling.

What’s is the probability of spinning a 4 on the spinner below
Answers
The probability of spinning a 4 on the spinner is 1/12.
Given, a spinner having two numbers 4 & 9
the sector having number 9 has an angle of 30°.
We have to find the probability of spinning a 4 on the spinner
So, the probability of spinning a 4 is,
Probability = (Area of sector having number 4)/(Area of the circle)
Probability = (30°/360°×π×r²)/(π×r²)
Probability = 1/12

Jada drank 12 ounces of water from her bottle. This is 60% of the water the bottle holds. How much water does the bottle hold?
Answers
Jada's water bottle holds 20 ounces of water.
Let the water bottle holds x ounces of water.
She drank 12 ounces of water.
this is equivalent to 60%
Hence 60% of x = 12
or, 0.6x = 12
or, x = 20 ounces
Therefore the bottle holds 20 ounces of water.
The English word percentage which refers to fractions with a denominator of 100, was derived from the Slang term "per centum," which means "by the hundred."
In other words, it is a connection where it is always assumed that the value of the whole is 100. The proportion of each reading to the total value is represented by the actual number whenever we have two or more readings that sum up to 100.

What is coordinate?A set of values indicating an exact position. On graphs, it is typically represented by a pair of numbers: the first number represents the distance along, and the second number represents the distance up or down. The location in the cartesian plane will be defined by the coordinate points. The distance between two points is known as the x-coordinate, or abscissa, and the distance between two points is known as the y-coordinate. To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to find the y-coordinate.
Here,
The starting coordinate=0,0
The second coordinate=-2,4
The ending coordinate=7,5
The required coordinate will be

One the second day they earned $256 for selling 100 cones and 30 sundaes.
What was the cost in dollars for each cone sold by the student council?
Answers
Answer:
1 cone = $1.36
Step-by-step explanation:
125 c + 10 s = $210
100 c + 30 s = $256
make one of the terms the same (easier one = 30 sundaes)
125 × 3 = 375 c
10 × 3 = 30 s
210 × 3 = $630
375 c + 30 s = $630
375 c + 30 s = $630
100 c + 30 s = $256
same sign = subtract
375 - 100 = 275 c
30 - 30 = 0 s
630 - 256 = $374
275 c = $374
÷ 275 on both sides to get c

Answers
We need to find the area of the sector which is given by the next formula:
Area of the sector = ( central angle / total angle ) * area of the circle
First, we need to find the area of the circle:
[tex]\begin{gathered} A_c=\pi\ast r^2 \\ Replacing \\ A_c=\left(12\right)^2\pi \\ A_c=144\pi \end{gathered}[/tex]Now, we can use the formula for the area of the sector
Central angle = 64
The total angle of a circle= 360
Area of the circle = 144π

Area of the sector = 128π/5
Area of the sector = 80.42477
