Answer:
B - 108
Step-by-step explanation:
A regular pentagon is 540 degrees. Divide 540 by 5 (since there are five sides) which equals 108 degrees.
Use the point-slope formula to write an equation of the line that passes through (1,0) and has a slope of m=-4. Write the answer in slope- intercept form ( if possible)
Answer:
y = -4x-4
Step-by-step explanation:
We need to find an equation of the line that passes through (1,0) and has a slope of m=-4.
The equation of a line is given by :
y = mx+c
Where
m is slope of line
Put all the values,
y = -4x+c
Put x = 1 and y = 0
So,
0 = -4(1)+c
c = -4
So, the required equation is :
y = -4x-4
Erven is painting canvases. Each canvas requires 4 ounces of paint. He has 21 ounces of paint. What
is the greatest number of canvases Erven could paint?
QUICKKKK PLEASEEE AND IN FRACTIONS
Answer:
5 1/4
Step-by-step explanation:
If each canvas takes up 4 oz of paint then you should take 21 and divide it by 4 to get the answer. Erven can only paint 5 full canvases and 1/4 of another canvas.
Circle A has a radius of 10 centimeters. and are tangent to circle A.
If AC = 26 cm, what is BC?
A)20cm
B)24cm
C)26cm
D)[tex]2\sqrt{194} cm[/tex]
Step-by-step explanation:
the answer is in the pic I posted! hope It helps...mark brainliest please!
The measure of BC is 24 cm. So, option B is correct.
Important information:
The diagram of a circle A with two tangents.Radius of circle A is 10 cm.AC = 26 cmWe need to find the measure of BC.
Tangent to circle:We have,
AD = AB = 10 cm
We know that the radius of a circle is perpendicular to the tangent at the point of tangency. It means triangle ABC is a right angle triangle.
Using the Pythagoras theorem, we get
[tex](AB)^2+(BC)^2=(AC)^2[/tex]
[tex](10)^2+(BC)^2=(26)^2[/tex]
[tex](BC)^2=676-100[/tex]
[tex](BC)^2=576[/tex]
Taking square root on both sides, we get
[tex]BC=\sqrt{576}[/tex]
[tex]BC=24[/tex]
The measure of BC is 24 cm. So, option B is correct.

Answer:
k = 1/4, m = 16Step-by-step explanation:
Scale factor is the ratio of the corresponding sides:
k = 7/28 = 1/4Find m using the scale factor:
m*1/4 = 4m = 16Answer:
scale factor is 4 and m is 16.
Step-by-step explanation:
This is because these are similar rectangles, so the proportion of each side to the congruent side is the same. This means that to get from 7 to 28 u multiply by a scale factor of 4, and to get m you would multiply 4 by 4.

Answer:
C) x²-2x-15=0
Step-by-step explanation:
You could put both -3 and 5 in the equations to guess and check, but the better way is to use them to create the factors. If -3 is a root, one of the factors must be (x+3). If 5 is a root, the other factor must be (x-5).
(x+3)(x-5)
x²-5x+3x-15=0
x²-2x-15=0

Find the exact value of each of the remaining trigonometric functions of theta.
Rationalize denominators when applicable.
sin theta= [tex]\sqrt{\frac{3}{7} }[/tex] given that theta is in quadrant I.
cos theta=
csc theta=
sec theta=
tan theta=
cot theta=
Answer:
See answers below
Step-by-step explanation:
Given that sin theta = √3/√7
Opposite =√3
Hypotenuse = √7
Get the adjacent
Adj² = (√7)²-(√3)²
Adj² = 7-3
Adj² = 4
Adj = √4
Adj = 2
Cos theta = adj/hyp = 2/√7
csc theta= 1/sin theta = 1/(√3/√7) =
√7/√3
sec theta= 1/costheta = 1/(2/√7) = √7/2
tan theta= opp./adj = √3/2
cot theta =1/tan theta = 1/(√3/2) = 2/√3
= 2√3/3
Suppose you have a bag with 10 black and 10 red balls, with the balls of each color numbered 1 to 10. Suppose you pick two balls uniformly at random from the bag.
a. Show that the probability that you pick a ball of each color is 10/19.
b. Show that the probability that you pick a ball of each color, with the number on the red ball being one less than the number on the black ball, is 9/190.
Answer:
Step-by-step explanation:
[tex]\text{From the given information:}[/tex]
[tex](a)[/tex]
[tex]\text{ P(ball of each color)=P(1st ball is black \& 2nd (red)) + P(1st(red) \& 2nd(black)})[/tex]
[tex]\text{ P(ball of each color)} = {P(1st (black) \times P(2nd \ red \ | \ 1st black) }+P(1st \ red) \times P(2nd \ black \ | \ 1st \ red)}[/tex]
[tex]\text{ P(ball of each color)} = \Big(\dfrac{10}{20}\Big ) \times \Big(\dfrac{10}{19}\Big ) + \Big(\dfrac{10}{20}\Big ) \times \Big(\dfrac{10}{20}\Big )[/tex]
[tex]\text{ P(ball of each color)} = \Big(\dfrac{10}{19}\Big )[/tex]
[tex](b)[/tex]
[tex]\text{If the combination of total no. of black \& red balls with no =10*10 =100}[/tex]
[tex]Then;[/tex]
[tex]\text{the no. of ways red is less than no. of black = 9}[/tex]
[tex]Thus:[/tex]
[tex]\text{P(ball of each color and number on red ball is 1 less than number of black ball is :)}[/tex][tex]= \text{P(ball of each color) * P(red is 1 less than black [] ball of each color)}[/tex]
[tex]=\Big( \dfrac{10}{19}\times \dfrac{9}{100} \Big )[/tex]
[tex]= \dfrac{9}{190}[/tex]

Mei runs 77.4 miles in 5 weeks. If she runs 3 days each week, what is the average distance she runs each day?
The average distance she runs each day is ____ miles.
Answer:
5.16
Step-by-step explanation:
We multiply the number of weeks by the number of days to find the total amount of days that she ran:
5 weeks × 3 days/week = 15 days
We are looking for the amount of miles/day (which represents the number of miles per day).
So, we take [tex]\frac{77.4miles}{15days}[/tex]= 5.16 miles/day

What is 3-6? Please help meeeee
your answer is going to be -3
Answer:
The Answer to 3-6 is -3!
Step-by-step explanation:
Think of it as a regular problem at first, 6-3: Switch the rolls!
6-3= 3 So when you switch the numbers back to 3-6, you get -3.
The answer has to have a negative sign (-) because it is a negative, a number below zero.
3-3= 0, 3 is half of 6, 6 is the number you need to subtract so you have to go below zero because subtraction is all about taking away from that first number. So 3-3= 0, 0-3= -3.
Hope that helped you!
