Answer:
y = 3x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (2, 10 )
m = [tex]\frac{10-4}{2-0}[/tex] = [tex]\frac{6}{2}[/tex] = 3
The y- intercept c = 4
y = 3x + 4 ← equation of line

Answer:
452.39
Step-by-step explanation:
to find the surface area of a sphere all you need is the radius (half the diameter) and assuming the sphere touches both top and bottom that makes the radius 6 so your equation is
SA=4πr^2
SA=4*π*6^2
SA=4*π*36
SA=4*113.09
SA=452.389
then rounded up to 452.39, that is your answer

equation: 7.84 / 7
Can someone pls help me find this is important
Answer:
x=90° and y=35°
Step-by-step explanation:
to get x and y first you must find the middle angles based on the information you have so:
35+90+n=180° solve for n to get what the middle angles are (since they are vertical angles they are equal) so the middle angles are both 55 degrees
and then 180-x=that angle that is also on the line with x so we'll call it k
so k+55+y=180°
we can see that y equals 35* because I noticed that those are parallel lines on the outside of the triangle so 35* and y angles are congruent and y =35°
now 35+55+k=180°
solve for the angle next to x which we called k and it is 90°
so x=90° and y=35°
after all this math I realized that if they are parallel lines then we can just use that to figure it out so use the properties to find out that x=90° and y=35°

Answer:- 1/6
Step-by-step explanation:
What is the value of the expression (x – y)2 when x = 5 and y = -1
A. 36
B. 16
C. 4
D. 24
Answer:
36
Step-by-step explanation:
You are given an expression and values to be put into it.
Simply substitute the values in instead of [tex]x[/tex] and [tex]y[/tex].
[tex](x-y)^2[/tex]
When [tex]x=5[/tex] and [tex]y=-1[/tex]:
[tex](5-(-1))^2 = (5+1)^2=(6)^2=36[/tex] - Note: Be careful with negative signs here. Two negatives make a positive.

Divide to get 70.5
turn into fraction
70 5/10=
70 1/2
Answer:
70 1/2
Step-by-step explanation:
first you have to divide 423 into 6 and then the remainder is the fraction so the answer is 70 5/10 or 70 1/2, same thing

A cone has a surface area of 200 pi square inches. If the radius of the
cone is 10 inches, find the length of the slant height.
Answer:
[tex]20\:\mathrm{in}[/tex]
Step-by-step explanation:
The lateral surface area of a cone is given by [tex]A=\pi r\ell[/tex], where [tex]r[/tex] is the radius of the base of the cone and [tex]\ell[/tex] is the cone's slant height.
Solving for [tex]\ell[/tex]:
[tex]200\pi=10\pi\ell,\\\ell=\frac{200\pi}{100\pi}=\boxed{20\:\mathrm{in}}[/tex]
*Note: It is implied that the surface area of 200 pi square inches is lateral surface area and not total surface area, because it is impossible to obtain a total surface area of 200 pi with a radius of 10 inches.

x = 12
Step-by-step explanation:
From Pythagorean theorem,
x^2 + 9^2 = 15^2
or
x^2 = 225 - 81 = 144
x = 12
Set up an equation for the value of x.
Answer:
x = 27
Step-by-step explanation:
∠ GAF = 90° , then
x + 63 = 90 ( subtract 63 from both sides )
x = 27
Answer:
27
Step-by-step explanation:
Angle x and 63 are complementary angles forming 90
Therefore,
90 - 63 = x
27 = x

Mark packed 1-inch cubes into a box with a volume of 96 cubic inches. How many layers of 1-inch cubes would it take to fill the box?
Answer:
4 approx.
Step-by-step explanation:
The number of layers of 1-inch cubes that Mark packed is determined by assuming that the larger box is also a cube.
let the N be the number of layers of 1-inch cubes that would it take to fill the box.
Since the larger box is also a cube
Therefore, 96 = N^3
N = (96)^(1/3)
N = 4√6
Therefore, there would be 4 layers of the 1-inch cube and some extra incomplete layer

find the length of the diagonals of rectangle QRST
Answer:
11:
since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=26
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=111

A ladder that is 6 meters long leans
against a building. The base of the
ladder is 1.5 meters from the base
of the building. To the nearest
hundredth of a meter, how far up
the building does the ladder reach?
Answer:
Height of building from base to ladder = 5.8 meter (Approx.)
Step-by-step explanation:
Given:
Length of ladder = 6 meters
Distance of ladder from base = 1.5 meters
Find:
Height of building from base to ladder
Computation:
Perpendicular = √Hypotenuse² - Base²
Height of building from base to ladder = √Length of ladder² - Distance of ladder from base²
Height of building from base to ladder = √6² - 1.5²
Height of building from base to ladder = √36 - 2.25
Height of building from base to ladder = √33.75
Height of building from base to ladder = 5.8 meter (Approx.)
About 25% of those called for jury duty will find an excuse to avoid it. If 12 people are called what is the probability that all 12 will be available. (Binomial distribution)
Answer:
Approximately [tex]0.032[/tex] (or, equivalently, [tex]3.2\%[/tex],) assuming that the availabilities of the [tex]12[/tex] jurors are independent from one another.
Step-by-step explanation:
The question states that the probability that a given juror is unavailable is approximately [tex]0.25[/tex].
For the complement of that event, the probability that this particular juror is available would be [tex]1 - 0.25 = 0.75[/tex].
Assume that the availabilities of the [tex]12[/tex] jurors are independent from one another. The number of available jurors would be a binomial variable with [tex]n = 12[/tex] and [tex]p = 0.75[/tex] ([tex]12\![/tex] independent observations, each with a [tex]0.75[/tex] probability of being "available".)
Hence, the probability that all [tex]12[/tex] jurors are available would be:
[tex](0.75)^{12} \times (0.25)^{0} \approx 0.032 = 3.2\%[/tex].

Answer:
Mode: 44 (mode is biggest number)
Mean: 30 (the average between numbers)
Step-by-step explanation:
Calculating the Mean
44 + 43 = 87
25 + 8 = 33
87 + 33 = 120
120 + 30 = 150
150/5 = 30

What is the measure of angle y?
a- 55 degrees
b- 145 degrees
c - 72.5 degrees
d - 35 degrees
Answer:
72.5
Step-by-step explanation:
Angle X is congruent to 35
both angles y and angle x together form a line that equals 180
so for angles y, take 180 - 35 = 145
Angles y is 145/2

3) We all know how toilet paper has been horded during the pandemic. Your teacher has cleared out a closet to hoard TP. Using the Fermi process, you need to estimate the number of rolls of TP she can fit into a rectangular prism section of a closet with dimensions of 36 in. By 108 in. By 36 in. Measure a roll of TP at your home, remember it is a cylinder you need its radius and height to calculate its size. Radius: __2in_______ Height: _5in___________ About how many rolls of TP can fit into the closet section?
Answer:
I rounded to 1,591 rolls of toilet paper can fit. I have the big rolls so I may fit less than the average roll.
Step-by-step explanation:
87.96 SA Per roll
140,000 Volume for the closet.
