Segment AB and AC are tangent to circle C find the value of X in the length of BC
9514 1404 393
Answer:
BC = 6
Step-by-step explanation:
Tangents from the same point are congruent, so ...
2x = x+3
x = 3 . . . . . . . subtract x
BC = x+3 = 3+3 = 6 . . . . . . substitute for x
The length of BC is 6.
convert the following to mixed number: 45/8

Divide the numerator by the denominator. 45 ÷ 8 = 5 with a remainder of 5.
Write down the whole number 5 and then write down the remainder as new numerator (5) above the denominator (8), As below : 5 58
Dean is the manager of a restaurant and is evaluating whether or not the restaurant has enough parking spaces. At ten different times during the day, he gathered information about the number of customers in the restaurant and the number of cars in the parking lot. He represented the data with the given scatter plot and drew the line of best fit.
Based on the line of best fit, approximately how many customers will be in the restaurant when there are cars parked in all 40 of the restaurant's parking spaces?
A.
115
B.
140
C.
145
D.
170
Answer:
there will be about 115 customer
Step-by-step explanation:
the y intercept is 2.5
(0,2.5) (100 ,35)
the slope is (y2-y1)/(x2-x1)
m = (35-2.5)/(100-0)
m= (32.5)/100
m = .325
y = mx+b
y = .325x+2.5
let y =40 for 40 cars in all the spot
40 = .325 x + 2.5
subtract 2.5
37.5 =.325 x
divide by .325
37.5 /.325 = x
115.4 = x
there will be about 115 customer

PLZ HELP A pantry contains cans of several different types of soup.
vegetable beef 22
black bean 3
chicken tortilla 12
cream of mushroom 1
minestrone 4
What is the probability that a randomly selected can will be black bean soup?
Write your answer as a fraction or whole number.
Answer:
3/42 or 1/14 if they have you reducing the number
Step-by-step explanation:
There are only 3 cans of black bean soup in the whole pantry. 3 is our numerator.
The denominator will be the total number of cans in the pantry, so
22 + 3 + 12 + 1 + 4 = 42
If you took a can of soup out of the pantry 42 times, 3 times it would be black bean soup

Answer:
EQUATION: c = 2.50m + 3
Step-by-step explanation:
you know the equation is C = 2.50m + 3 because if you look at the sentence and pick it apart to better understand it you'll see in the first sentence that 3 PLUS 2.50 PER MILE. your key words are of course plus and per mile. So, in conclusion you say for every mile you have to pay 2.50 but they don't give you the number for how many miles you'd drive so automatically it's your missing value.
A line passes through the points (3,-12) and
(6, K). The slope of the line is -2. Determine
the value of K.
Answer:
k = - 18
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 2
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, - 12) and (x₂, y₂ ) = (6, k)
m = [tex]\frac{k+12}{6-3}[/tex] = [tex]\frac{k+12}{3}[/tex] = - 2 ( multiply both sides by 3 )
k + 12 = - 6 ( subtract 12 from both sides )
k = - 18

In the figure shown , which is the value of y?
I’m failing I really need help please!
Answer:
3 and -4
Step-by-step explanation:
this is simple but difficult
let the number be x and second number be y
3x + 2y=1
x-y/2=5
from the 2nd equation
x-y/2=5
x=5+y/2
substitute value for x into equation 1
3x + 2y=1
3(5+y/2) + 2y= 1
15 +3y/2 +2y=1
15 + 7y/2=1
7y/2= 1 - 15
7y/2=-14
cross multiply
7y= -28
y= -28/7
y= -4
therefore second number is -4
substitute value for y into 1st equation
3x + 2y=1
3x + 2(-4) = 1
3x - 8= 1
3x= 1+8
3x= 9
x= 9/3
x= 3
therefore first number is 3
therefore two numbers are;
3 and -4
The measures of the exterior angles of a triangle are 2x°,6x°, and 7x°. Solve for x.
Answer:
24 degrees
Step-by-step explanation:
The sum of the exterior angles of a triangle is 360 degrees
2x + 6x + 7x = 360
15x = 360
x = 24
Answer:
x=24
Step-by-step explanation:
2x+6x+7x=360
15x=360
15x/15=360/15
x=24

Math question please show work due today last day to submit Assignments or I fail please help
Answer:
A. 41
B. 1,590
C. .1
Step-by-step explanation:
A.
the equation is l*w=A
9.2*4.5=A
41.4=A
rounded it would be 41
B.
the equation is pi*r^2=A
3.14*22.5^2=A
3.14*506.25=A
1,589.6=A
^round this up to get 1,590
C.
what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)
.5*.2/2=A
.1/2=A
.05=A
.05+.05=0.1
Answer:
[tex]\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}[/tex]
Step-by-step explanation:
Part A:
The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].
What we're given:
[tex]b[/tex] of 9.2[tex]h[/tex] of 4.5Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]
Part B:
The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]
Part C:
The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].
What we're given:
[tex]b[/tex] of 0.4[tex]h[/tex] of 0.5Substituting given values, we get:
[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]

help me find the slope of these points
Answer:
- [tex]\frac{2}{3}[/tex] and [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = S(12, 9) and (x₂, y₂ ) = T(21, 3)
[tex]m_{ST}[/tex] = [tex]\frac{3-9}{21-12}[/tex] = [tex]\frac{-6}{9}[/tex] = - [tex]\frac{2}{3}[/tex]
Repeat with
(x₁, y₁ ) = S'(4, 3) and (x₂, y₂ ) = T'(7, 1)
[tex]m_{S'T'}[/tex] = [tex]\frac{1-3}{7-4}[/tex] = - [tex]\frac{2}{3}[/tex]
-----------------------------------------------------------
(x₁, y₁ ) = R(24, 18) and (x₂, y₂ ) = S(12, 9)
[tex]m_{RS}[/tex] = [tex]\frac{9-18}{12-24}[/tex] = [tex]\frac{-9}{-12}[/tex] = [tex]\frac{3}{4}[/tex]
Repeat with
(x₁, y₁ ) = R'(8, 6) and (x₂, y₂ ) = S'(4, 3)
[tex]m_{R'S'}[/tex] = [tex]\frac{3-6}{4-8}[/tex] = [tex]\frac{-3}{-4}[/tex] = [tex]\frac{3}{4}[/tex]
