x= ___
Question 2
Do the side lengths form a Pythagorean triple?
Yes [ ]
No [ ]
Answer:
x = 15
yes
Step-by-step explanation:
17²= 289
8²= 64
A² + B² = C²
8²+ B² = 17²
64 + B² = 289
-64 -64
B²= 225
√225
B = 15

I need help finding the rate of change can someone help me
Answer:
rate of change is 4.
Step-by-step explanation:
rate of change is the slope, so, pick any two relations given to us in the table.
(-3, -14) and (-1, -6).
slope = y2 - y1/ x2 - x1
slope = -6 - (-14)/-1-(-3)
slope = 8/2 = 4.
the rate of change is 4.

Tell which term you would add or subtract on both sides side of the equation so that the variable is only on one side. 10 - y = 2y + 3
Answer:
add +y to both sides
Step-by-step explanation:
10 - y = 2y + 3
+y +y
^it will cancel out the -y
10=3y+3
HELP FIND THE AREA PLS BRAINLY WILL BE GIVEN
Answer:
the area is 60 square units
Step-by-step explanation:
Area = (base x height) / 2
from class 1 to 2 is 10 units
from class 2 to 3 is 12 units
10 x 12 / 2
10 x 12 = 120

Please hellllp fasttttttt
Answer:
Step-by-step explanation:
Because lines [tex]m[/tex] and [tex]n[/tex] are parallel, angles 1, 3, 4, 6 are equivalent, and all remaining angles are also equivalent.
Knowing this, you can set up the following equation:
[tex]86 = 2x + 25[/tex]
[tex]86 - 25 = 2x[/tex]
[tex]61 = 2x[/tex]
[tex]x = 30.5[/tex]

Answer:
Please answer my question
Answer:
a = 15, b = - 14
Step-by-step explanation:
Given the 2 equations
[tex]\frac{a}{5}[/tex] - [tex]\frac{b}{2}[/tex] = 10 ( multiply through by 10 to clear the fractions )
2a - 5b = 100 → (1)
a - b = 29 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the a- term
- 2a + 2b = - 58 → (3)
Add (1) and (3) term by term to eliminate a
0 - 3b = 42
- 3b = 42 ( divide both sides by - 3 )
b = - 14
Substitute b = - 14 into (2) and evaluate for a
a - (- 14) = 29
a + 14 = 29 ( subtract 14 from both sides )
a = 15
The length of a triangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle.
Answer:
Length = 32 feet
Width = 12 feet
Step-by-step explanation:
From the question;
Width = w
Length = 2w + 8
But the perimeter of a rectangle = 2(l + b)
perimeter = 88 feet
88 = 2(2w + 8 + w)
88 = 2(3w + 8)
88 = 6w + 16
88 - 16 = 6w
72 = 6w
w = 72/6
w = 12 feet
Hence;
Length = 2(12) + 8 = 32 feet
Dimensions of the rectangle is;
Length = 32 feet
Width = 12 feet
Six jurors are to be selected from a pool of potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, of the prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If jurors are selected at random from this group of , find the probability that the number of potentially prejudiced jurors among the selected jurors is exactly .
Complete question :
Six jurors are to be selected from a pool of 20 potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, 2 of the 20 prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If 6 jurors are selected at random from this group of 20, find the probability that the number of potentially prejudiced jurors among the 6 selected jurors is ;
a. exactly 1
b. none
c. at most 2
Answer:
0.442 ; 0.479 ; 1
Step-by-step explanation:
Given:.
Total number of candidates = 20
Number of jurors to be selected = 6
Number of prejudiced jurors = 2
Required outcome / Total possible outcomes :
Using the combination formula :
nCr = n! ÷ (n-r)!r!
1.)
P(number of prejudiced jurors is exactly 1) :
[2C1 * 18C5] ÷ 20C6
(2*8568)÷ 38760
= 0.442
B.)
P(None of the jurors is prejudiced) :
[2C0 * 18C6] ÷ 20C6
(1 * 18564) ÷ 38760
= 0.479
C.)
P(at most 2 of the jurors are prejudiced)
P(x =0) + p(x = 1) + p(x = 2)
P(x = 2) :
[2C2 * 18C4] ÷ 20C6
(1 * 3060) ÷ 38760
= 0.079
P(x =0) + p(x = 1) + p(x = 2)
(0.479 + 0.442 + 0.079)
= 1

find the side length
Answer:
area of square=side²
36/49yd²=side²
(36/49yd²)²=side
6/7 yd=side
Answer:
s = [tex]\frac{6}{7}[/tex] yd
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the length of side )
Given A = [tex]\frac{36}{49}[/tex] , then
s² = [tex]\frac{36}{49}[/tex] ( take the square root of both sides )
s = [tex]\sqrt{\frac{36}{49} }[/tex] = [tex]\frac{\sqrt{36} }{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]
Write an expression that is equivalent to 8(a + 5).

Shanice spent half of her weekly allowance on cloths. To earn more money her parents let her clean the gutters for $7. What is her weekly allowance if she ended with $14?
Answer:
$14
Step-by-step explanation:
After Shanice spent half of her allowance and earned $7, she is left with $14.
This means the remaining of her weekly allowance is $7, This can be derived by subtracting $7 from 15 - $14 - $7 = $7
This means that it is $7 that remains after spending half of her weekly allowance
her weekly allowance = $7 x 2 = $14
11/12 - (-10) - 5/6 as a single rational number
Answer:

1. 11/12 - (-10) = 11/12+10 = 131/12
2. 131/12-5/6 = 131/12 - 10/12 = 121/12
WILL GIVE BRAINLIEST!!!!!!! find the value of x. find the value of y.
Answer: x=20 y=20√2
Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)
Solve and graph y−5<7
Answer:
y < 12
Step-by-step explanation:
Add 5 on both sides since the opposite of subtraction is addition. Then cross it out where you will be left with y and 7 + 5 equals 12 so the answer is: y < 12
