What would be the algebraic rule for a dilation with a scale factor of 3?
Answer: multiply each point by 3. You would need to multiply both the x and y value in the point to find the new dilated point.
Step-by-step explanation:
Suppose that the length of a certain rectangle is two centimeters more than three times its width. If the area of the rectangle is 85 square centimeters, find its length and width
Answer:
width = 5 in
length = 17 in
Step-by-step explanation:
Area of a rectangle = length x width
width = w
length = 2 + 3w
85 = (w) x (2 + 3w)
85 = 2w + 3w³
this can be solved using quadratic equation
3w³ + 2w - 85 = 0
factors of 3w³ x -85 that add up to 2w are : +17 w and -15w
(3w³ - 15w) (17w - 85) = 0
3w(w - 5) 17(w - 5) 0
w = 5
or w = - 17/3
the width cannot be a negative number. the correct width is 5 in
Length = 2 x 3(5) = 17 inches
Mr. Garner purchased a party hall and wants to repaint it as part of the renovations. He needs to calculate the lateral surface area of the party hall so that he will know how much paint to buy. The party hall is in the shape of a rectangular prism with the dimensions shown below. Including the doors, what is the lateral surface area of the party hall in square feet?
Answer:
The lateral surface area of the rectangular prism is 204 square feet
Step-by-step explanation:
The remaining part of the question is attached
Solution
Lateral surface area of a rectangular prism is
Height of the prism * perimeter of the base of the prism.
Substituting the given values, we get-
Lateral surface area of a rectangular prism =
[tex]0.5 *12 * 2(12+5)\\0.5*12*2*17\\0.5*408 \\204[/tex]
The lateral surface area of the rectangular prism is 204 square feet
Find the area. The figure is not drawn to scale.
a
30 yd2
b
6.5 yd2
c
15 yd2
d
13 yd2
Answer:
The area if the triangle is 15 yd^2
Step-by-step explanation:
The formula to find the area if a triangle is base × height ÷ 2. So for this question it is 10×3÷2=15
Find the slope of the line on the graph.
Write your answer as a fraction or a whole
number, not a mixed number or decimal.
Answer:
The slope is 1
Step-by-step explanation:
Take any two points from the graph and plug it into the equation y1-y/x1-x. I took the point (0,3) and (1,4). Plug these two points in to get 4-3/1-0. Simplify to get 1/1 which is equal to 1. Therefore, the slope is 1.
If this answer helps please mark as brainliest
Answer:
The slope is 1
Step-by-step explanation:
There are multiple ways to find the slope on a graph. You can either take two points from the line and do it the normal way (y1-y2/x1-x2), or you can look at the graph and see how much it "rises and runs" from one point to the next point. Since this is a pretty simple graph that is the method I used. Count how many units the line goes up and to the right from one point to the next, and remember the phrase "rise over run" for organizing the fraction. In this one, it rises one and runs one, so 1/1, and that's 1. I hope I could help.

There are 20 marbles in the box. 4 marbles are black, 6 marbles are blue, 10 are red. What is the probability of drawing a black OR a red marble?
Answer:
7/10 or 70% or 0.7
Step-by-step explanation:
4 black, 10 red
10+4=14
now you put it over the total marbles
14/20=7/10
i don't know how your teacher wants you to give the answer but it is 7/10 or 0.7 or 70%

Answer:
volume = 24,501.42
Step-by-step explanation: the way i did it:
first find the radius, 34 divided by 2 = 17π
then multiply the radius by itself 17 x 17 = 289
after, multiply 289 by 27 to get 7,803
then multiply 7803 by 3.14 to get 24,501.42
Hope this is correct!
(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84
easy question for anyone SLIGHTLY smarter than me pls help I don’t know how to do this
They make it all so complicated with all of the complex lines doing their own thing, though this is somewhat straight forward once you see it.
With the Domain, these are the x values that the line covers.
For this, it would be -5 ≤ x ≤ 4, because all of the x values are between these two values.
With the Range, these are the y values that the line covers.
For this, it would be -4 ≤ x ≤ 5, because all of the y values are between these two values.
With the X-Intercepts, these are the x values the line crosses for when the y value is 0.
For this, it would be -3 and -1.
With the max, it is the highest point within a graph, for where the y value is the greatest.
For this, it would be x = 4 at the coordinate (4, 5).
Right triangle XYZ is drawn with a 23° angle. For right triangles with an angle of 23° the ratio of the leg adjacent the 23° angle compared to the hypotenuse is 0.92 If the leg adjacent to the 23° angle has a length of 46 units, what is the length of the hypotenuse?
Answer:
50
Step-by-step explanation:
In a right angled triangle :
Ratio of the leg Adjacent an angle to the hypotenus can be obtained using the Cosine trigonometric ratio
For an angle of 23° and and adjacent leg of 46
Cos 23 = adjacent / hypotenus
Adjacent / hypotenus = 0.92
46 / hypotenus = 0.92
Hypotenus = 46 / 0.92
Hypotenus = 50
Need help ASAP! What is this
180 - 64= 116
116 divided by 4 = 29
x=29
Have a good day:>
Answer:
x = 29
Step-by-step explanation:
Supplementary angles add up to 180 degrees:
4x+64 = 180
Subtract 64 from both sides:
4x+64-64 = 180-64
4x = 116
Divide both sides by 4:
4x/4 = 116/4
x = 29

Please help me find the missing side and show your work
Answer:
9 yards
Step-by-step explanation:
The Pythagorean theorem: [tex]a^2+b^2=c^2[/tex]
Where a and b are legs, and c is the hypotenuse.
The hypotenuse is the side opposite from the right angle in the right triangle.
The hypotenuse would be AC, measured 15 yards, because it is opposite from the right angle. BC, the unmeasured side would be a leg. I can call that the "b" leg and AB, the 12 yard side the "a" leg.
Substitute the measures into the theorem to get: [tex]12^2+?^2=15^2[/tex]
[tex]144+?^2=225 ; ?^2=81; ?=\sqrt{81} =9[/tex]
