We will use the Pythagorean Theorem:
[tex] {17}^{2} = {8}^{2} + {x}^{2} \\ 289 = 64 + {x}^{2} \\ {x}^{2} = 289 - 64 \\ {x}^{2} = 225 \\ x = \sqrt{225} \\ x = 15[/tex]
The length of the angle is 15cm
How many joules of gravitational potential energy does a 15 kg object have when it is lifted from the floor and held 0.6 meters above the ground?
Answer:
88.29joules
Step-by-step explanation:
mgh=gravitational potential energy
(15kg)(9.81)(0.6)= 88.29joules

Write the standard equation of the circle with center (-12, – 7) that passes through the point (-3,7).
Answer:
[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In which r is the radius.
Center (-12, – 7)
This means that [tex]x_0 = -12, y_0 = -7[/tex]. So
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - (-12))^2 + (y - (-7))^2 = r^2[/tex]
[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]
Passes through the point (-3,7).
This means that we use [tex]x = -3, y = 7[/tex] to find the radius squared. So
[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]
[tex](-3 + 12)^2 + (7 + 7)^2 = r^2[/tex]
[tex]81 + 196 = r^2[/tex]
[tex]r^2 = 277[/tex]
The equation of the circle is:
[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]
[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]
of Kayla has a bowl of beads that contalns 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. She randomly draws a bead from
the bowl.
The probability of Kayla not drawing yellow or a green bead is
%. The probability of Kayla drawing red or a green bead is
%.
Answer:
a) You have a 30% of not drawing yellow or green
b) You'd have a 46% of frawing a red or green bead
Step-by-step explanation:
Total beads: 42 + 28 + 12 + 18 = 100
Green beads + yellow beads = 28 + 42 = 70
100 - 70 = 30
30/100 = 0.3 or 30%
Red beads + green beads = 18 + 28 = 46
46/100 = 0.46 or 46%
Answer:
1. 30%
2.46%
Step-by-step explanation:
The probability of Kayla not drawing a yellow or a green bead is 30 %. The probability of Kayla drawing a red or a green bead is 46 %.

Step-by-step explanation:
24=3(n-5) what does n equal
Answer:
The answer is n = 13
Step-by-step explanation:
1) Divide both sides by 3.
[tex] \frac{3}{24} = n - 5 [/tex]
2) Simplify 24/3 to 8.
[tex]8 = n - 5[/tex]
3) Add 5 to both sides.
[tex]8 + 5 = n[/tex]
4) Simplify 8 + 5 to 13.
[tex]13 = n[/tex]
5) Switch sides.
[tex]n = 13[/tex]
Therefor, the answer for this equation is n = 13.

What’s the answer to this math problem?
The Department of Homeland Security wants to test a computer virus that it has developed to combat hackers. They plan to test run the virus on randomly selected computers with pre-set "hacker" programs.
choose one:
-census
-cluster sampling
-convenience sampling
-simple random sampling
-stratified sampling
choose one:
-experiment
-observational study
-simulation
-survey
Answer:
Simple random sampling
Observational study
Step-by-step explanation:
Since in the given situation it is mentioned that department wants to test the computer virus and have to run the virus on the random selected computers so here the simple random sampling would be done and based on the simple random sampling the observational study would be done
Therefore the above represent the answer
Answer:it is simple random sampling but the collection method is not observational study I got that part wrong

RQ= x+1 QP=7 RP=2x+8 solve for RP
Answer:
RP = 8
Step-by-step explanation:
RQ + QP = RP (segment addition theorem)
(x + 1) + 7 = 2x + 8 (substitution)
Add like terms
x + 8 = 2x + 8
8 - 8 = 2x - x
0 = x
x = 0
✔️RP = (x + 1) + 7
Plug in the value of x
RP = (0 + 1) + 7
RP = 1 + 7
RP = 8

Answer:
y = 1
Step-by-step explanation:
-3y + 14 + y = 12
-3y + y + 14 = 12
-2y + 14 = 12
-2y + 14 - 14 = 12 - 14
-2y = -2
-2y/-2 = -2/-2
y = 1
Answer:
y=1
Step-by-step explanation:
Hey There!
So to solve this type of problem we use inverse operations
-3y+14+y=12
step 1 subtract 14 from each side
14-14
12-14=-2
now we have
-3y+y=-2
step 2 combine like terms
-3y+y=-2y
now we have -2y=-2
step 3 divide each side by -2
-2/-2=1
so we can conclude that y=1
If an exterior angle measure of a regular polygon is 60°, how many sides does the polygon have? What is the measure of each interior angle?
9514 1404 393
Answer:
6 sides120°Step-by-step explanation:
The sum of the measures of the exterior angles of a convex polygon is always 360°. If each is 60°, there are 360°/60° = 6 of them.
There are 6 sides.
The adjacent interior angle is the supplement of the exterior angle, so is ...
180° -60° = 120°.
Each interior angle measures 120°.

cara played a card game using a deck of 52 cards after she dealt the same number of cards to 4 players she had 24 cards left over how many cards did each player get
Answer:
7Step-by-step explanation:
Assume each player get x cards. Total number of cards now is 4x+24=52.
Therefore, 4x=52-24=28.
Then, x= 28/4=7.

A = 4
B = 9
C = 11
D = A + 2B - C
D = ?
Answer:
D = 11
Step-by-step explanation:
A = 4
B = 9
C = 11
D = 4 + (2 * 9) - 11

Step-by-step explanation:
This is a question that bothers on selection
Using the combination formula
nCr = n!/(n-r)!r!
20C12 = 20!/(20-12)!12!
20C12 = 20!/8!12!
20C12 = 20*19*18*17*16*15*14*13*12!/8!12!
20C12 = 20*19*18*17*16*15*14*13/8!
20C12 = 20*19*18*17*16*15*14*13/8*7*6*5*4*3*2
20C12 = 5,079,110,400/5040
20C12 = 1,007,760
Hence this can be done 1,007,760 different ways

3x-4y=-2
3y-2x=1
Answer:
y = -1, x = -2
Step-by-step explanation:
First, multiply the top equation by 2 to make 3x become 6x:
6x - 8y = -4
Second, multiply the bottom equation by 3 to make -2x become -6x:
9y - 6x = 3
Add the two equations together, and you get:
y = -1
Plug in y as -1 into the first or second equation:
3x - 4(-1) = -2
OR
3(-1) - 2x = 1
x = -2
-x^2+4x-8
axis of symmerty
Answer:
[tex]\boxed {\boxed {\sf x=2}}[/tex]
Step-by-step explanation:
The axis of symmetry can be calculated using the formula:
[tex]x=\frac{-b}{2a}[/tex]
First we must determine a and b from the quadratic: [tex]-x^2+4x-8[/tex]. This is in standard form, with the highest power first in descending order.
Standard form is also: [tex]ax^2+bx+c[/tex]
If we compare this to the quadratic given, we can conclude that:
[tex]a= -1 \\b= 4 \\c= -8[/tex]
Substitute the values for a and b into the formula.
[tex]x= \frac{-(4)}{2(-1)}[/tex]
Multiply in the denominator.
[tex]x=\frac {-4}{-2}[/tex]
Divide.
[tex]x=2[/tex]
This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
Find the missing sides of the triangle. Leave your answers in simplest radical form.
Answer:
B) x=2, y=2
Step-by-step explanation:
B.
It’s a 90-45-45 triangle, so the hypotenuse is x√2, and the other two sides are x. Since this x is 2, the other two sides are 2.
