What is m∠1?....................
answer is 147
hope that helped
Answer:
m∠1 = 147°
Step-by-step explanation:
triangle = 180°
117 + 30 = 147
180 - 147 = 33
line = 180°
180 - 33 = 147
m∠1 = 147°
In 2011, 39 people died by being struck by lighting, and 24 people were injured. There were l 310,000,000 people in the United States. What is the probability of being one of the people struck by lighting
Answer: 0.0000203%
Step-by-step explanation:
The total number of people struck by lightning includes both those who died and those who were injured:
= 39 + 24
= 63 people
Probability of being struck is:
= People struck / U.S. Population
= 63 / 310,000,000
= 0.0000203%

A group of students go to the store to buy school supplies. If they buy three
binders and four notebooks, the bill will be $4.85. If they buy three binders and
ten notebooks, the bill will be $8.75. What is the cost of each binder and
notebook?
Answer: Binder = 75c notebook = 65c
Step-by-step explanation:
3b + 10n = 875
3b + 4n = 485
Subtracting gives:
6n = 390
390/6 = 65
n = 65
Substitute 65 into 3b + 4n = 485
3b + 260 = 485
3b = 485 - 260
3b = 260
b = 75
It costs $16 for 8 specialty chocolates for Valentines Day. Find the unit rate 5 per item (how much for 1 chocolate).
Answer:
Unit Rate: 2$ per chocolate
If you're buying 5, it will cost $10
Step-by-step explanation:
Finding the unit rate:
16 ÷ 8 = 2
2 x 5 = $10
If you're talking about what happens if each chocolate cost $5 per item it would be
$5 x 8 chocolates = $40
I hope this helped! :)
Find the slope that passes through the line (9, 3) and (2, 7)
Answer:
-4 / 7
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
m = (7 - 3) / (2 - 9)
m = 4 / -7
m = -4 / 7
OR
m = (y2 - y1) / (x2 - x1)
m = (3 - 7) / (9 - 2)
m = -4 / 7
At the zoo the ratio of monkeys to gorillas is 5:1 if there were 20 monkeys how many gorillas would there be?
Answer:
4
Step-by-step explanation:
To get to 20 you have to multiply 5 by 4 so do the same with the 1 and multiply by 4 to make it proportional. 1 x 4= 4. There would be 4 gorillas
I need help with these questions. Please show workings.
Answer:
see explanation
Step-by-step explanation:
∠ AOB = 360° - 264° = 96°
The altitude OM bisects ∠ AOB and the base AB
(a)
∠ MOB = 0.5 × 96° = 48°
Using the cosine ratio in right triangle MOB
cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{OB}[/tex] = [tex]\frac{18}{r}[/tex] ( OB is the radius r of the circle )
Multiply both sides by r
r × cos48° = 18 ( divide both sides by cos48° )
r = [tex]\frac{18}{cos48}[/tex] ≈ 27 cm ( to the nearest cm )
(b)
Using the tangent ratio in the right triangle MOB
tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{MB}{OM}[/tex] = [tex]\frac{MB}{18}[/tex] ( multiply both sides by 18 )
18 × tan48° = MB then
AB = 2 × MB = 2 × 18 × tan48° = 36 × tan48° ≈ 40 cm ( to nearest cm )
help 8+x2=−12..im confused
Answer:
Step-by-step explanation:
No real solutions exist. Subtract 8 on both sides to get:
[tex]x^2=-20[/tex]
You cannot take the square root of a negative number without involving imaginary numbers.
Answer and Explanation
__________________________________________________________
-10__________________________________________________________
The answer is -10 because...
You need to multiply 2 by "x," and to find out what "x" is, we need to add...
[tex]2+-12[/tex]
__________________________________________________________
And if we add [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.
__________________________________________________________
and now, if we add [tex]-20[/tex] by [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.
