TIMED QUESTION.
The angles of a triangle are hº, (3h)º, and (h-5)°. What is the value of h?
Answer:
h=37
Step-by-step explanation:
h + 3h + (h-5) =180
5h-5=180
5h=185
divide by 5
Durng lunch hour at a local reastrunt 90% of custmors order a meat entree and 10% order a vegetarian entree of the custmors who order a meat entree 80% order a drink of the custmors who order a vegitarian entree 40% order a drink what is the percent of custmors who order a drink for there entree
Answer:
First, here we must use the decimal notation for the percentages.
if we have a percentage x%, the decimal notation will be:
x%/100%.
Then for example, if x% = 90%.
the decimal notation will be:
90%/100% = 0.90
Data that we have:
90% order a meat entree, and 80% of these, order a drink.
So the percentage here that orders a drink is:
(0.9*0.8)*100% = 0.72*100% = 72%
10% order a vegetarian entree, and 40% of those order a drink, so the percentage here that orders a drink is:
0.1*0.4*100% = 0.04*100% = 4%.
Then the total percentage that orders drinks is 72% + 4% = 76%
76% of the customers that order an entree (meat or vegetarian) also order a drink.

What is the simplified form of the following expression?
Answer:
242
Step-by-step explanation:
Simplify the following:
11 ((9^2 - 5^2)/2^2 + 8)
Hint: | Evaluate 2^2.
2^2 = 4:
11 ((9^2 - 5^2)/4 + 8)
Hint: | Evaluate 5^2.
5^2 = 25:
11 ((9^2 - 25)/4 + 8)
Hint: | Evaluate 9^2.
9^2 = 81:
11 ((81 - 25)/4 + 8)
Hint: | Subtract 25 from 81.
| 7 | 11

11 (56/4 + 8)
Hint: | Reduce 56/4 to lowest terms. Start by finding the GCD of 56 and 4.
The gcd of 56 and 4 is 4, so 56/4 = (4×14)/(4×1) = 4/4×14 = 14:

What is the equation of a line through point (-4,5) that is perpendicular
to the line with equation y= -6x+4?*
Answer:
set two equation of line y=ax+b and y=cx+d
when these two lines are perpendicular to each other, then a*c=(-1)
set answer is y=ax+b
we can know that a=1/6
bring in a=1/6 and(-4,5)
5=(1/6)*(-4)+b
=>5=(-2/3)=b
=>b=5 2/3
answer is y=(1/6)x+5 2/3

Jane uses 16 gallons of gas and the gas mileage of her vehicle is 20 mpg. How many miles did she drive?
Combining like terms!!
3.) 4x + 6 = 14
Answer:
x=2
Step-by-step explanation:
4x + 6 = 14
4x = 14 - 6
4x = 8 (divide both sides by 4 to get x)
4x/4 = 8/4
x = 2
Answer:
Subtract 6 from both sides of the equation
4+6−6=14−6
Simplify
Subtract the numbers
4x+6−6=14−6
4=14−6
Subtract the numbers again
4x=14−6
4=8
Divide both sides of the equation by the same term
4=8
4 4
Cancel terms that are in both the numerator and denominator
x= 8
4
Divide the numbers
= 2

If a triangle is equiangular, does it have to be equilateral?
4+x = 5x+2. find x. 180 is the total of this equation
Answer:
x=
Step-by-step explanation:
4+x-2=5x+2-2
2+x-x=5x-x
2=4x
2/4
Answer:
x = 45.5
Step-by-step explanation:
Move one side of the equation to the other side of the equal sign.
4 + x = 5x + 2
x = 5x - 2
=4x - 2
Then put the 180 on the empty side because the total is 180.
180 = 4x - 2
Then solve for x
182 = 4x
45.5 = x

The graph of a linear relationship is shown. Which equation best represents the relationship between x and y in the graph
Answer:
B. y = -3/4x + 5/2
Step-by-step explanation:
Take two points from the graph, let's use (-2, 4) and (2, 1):
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (2 - (-2))
= -3/4
Find y-intercept using slope above and anyone point:
y = mx + b
(1) = -3/4(2) + b
1 = -3/2 + b
b = 1 + 3/2
b = 5/2
Equation of line using m and b above:
y = mx + b
y = -3/4x + 5/2
Answer:
B. y = -3/4x + 5/2
Step-by-step explanation:
B. y = -3/4x + 5/2
Take two points from the graph, let's use (-2, 4) and (2, 1):
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (2 - (-2))
= -3/4
Find y-intercept using slope above and anyone point:
y = mx + b
(1) = -3/4(2) + b
1 = -3/2 + b
b = 1 + 3/2
b = 5/2
Equation of line using m and b above:
y = mx + b
y = -3/4x + 5/2
that is why hope it helps
The question is in the picture please explain.
Answer:
x = 78
Step-by-step explanation:
Look at Triangle DBH. Two of its angles are known. Let y = <DHB
47 + 31 + y = 180 All triangles have 180 degrees. Combine the left.
78 + y = 180 Subtract 78 from both sides.
78-78+y = 180-78 Combine
y = 102
Notice that y + x = 180 They form a straight line.
102 + x = 180 Subtract 102 from both sides.
x = 78
You should notice that x is an exterior angle. (I didn't at first).
Exterior angles are the sum of the two remote interior angles which in this case, are 31 + 47 = 78

25 fewer than twice a number?
Answer:
2x - 25
Step-by-step explanation:
Since we don't know what the number is, just call it x. Twice x can be written as 2x and 25 fewer than 2x is 2x - 25.
Identify the two consecutive integer in which each square root lies between. A. 11,12 B.12,13 C.13,14 D.14,15
Answer: C
Step-by-step explanation:
An investor invested a total of $14,000. She divided the money into three different accounts. At the end of the year, she had made $670 in interest. The annual yield on each of the three accounts was 4%, 5%, and 6%. If the amount of money invested in the 5% account was the same as the combined amount invested in the 4% and the 6% accounts, determine how much was invested in the account that paid 6% interest.
Answer:
$2000
Step-by-step explanation:
Given the following :
Total amount invested = 14000
Total interest earned = 670
Amount invested in 4% (0.04) account = a
Amount invested in 6% (0.06) account = b
Amount invested in 5% (0.04) account = a + b
a + b + (a + b) = 14000
2a + 2b = 14000
a + b = 7000 - - - (1)
Simple interest = principal * rate * time
(a * 0.04) + (b * 0.06) + [(a+b) * 0.05] = 670
0.04a + 0.06b + 0.05a + 0.05b = 670
0.09a + 0.11b = 670 - - - - (2)
from (1)
a = 7000 - b
0.09(7000 - b) + 0.11b = 670
630 - 0.09b + 0.11b = 670
= 630 + 0.02b = 670
0.02b = 670 - 630
0.02b = 40
b = 40/ 0.02
b = $2000
Amout invested in 6% account = $2000

NEED HELP ASAP WILL GIVE BRANLIEST
Answer: B
Step-by-step explanation:
Use the formula cos(A-B) = cosA cos B + sin A sin B.
if you use the Pythagorean theorem to find the other sides of Triangle A and B and use them to find the cosine of A and B, you should get:
(4/5)(sq rt of 5/3) + (3/5)(2/3)
(4 sq rt of 5/15) + (6/15)
4 sq rt of 5 + 6/15

Mr. Ha-Ha is a circus clown at the town carnival. He starts the day with 68 pieces of candy. At the end of the day he has given away 383 pieces of candy. How many more pieces of candy did he have to get to be able to give away that many pieces?
Answer:
He already had = 68 candies
Total given by him = 383 candies
Required more by him = 383 - 68
=> 315 candies
So, he bought an additional 315 candies
