Hope this helpsA purple hot-air balloon is 90 feet off the ground and rising at a rate of 7 feet per second. A yellow hot-air balloon is 120 feet off the ground and rising at a rate of 4 feet per second. Which equation could represent this situation and determine after how many seconds, s, the purple hot-air balloon will be the same height as the yellow hot-air balloon?
1 point
90 + 7s = 120 + 4s
7s + 120 = 4s + 90
90s + 7 = 120s + 4
11s = 210
90+7s = 120 + 4s
11s = 210
Determine the area under the standard normal curve that lies to the right of the z-score of 1.44. (Use a four-digit decimal. No rounding necessary.)
Answer:
The area is 0.0749
Step-by-step explanation:
The area under the standard normal curve represents probability and has a total value of 1
Now, to the right of the z-score 1.44, the area we are considering is the probability below;
P( z > 1.44)
To get this value, we need to use the standard normal distribution table
Checking this, the probability is
P( z > 1.44) = ) = 0.074934 which is 0.0749 for a four decimal digit

Shaun and trudy are selling raffle tickets. So far shaun has sold x tickets. Trudy has sold 3 more tickets than half the number of tickets that shaun sold.what expression represents the number of raffle tickets that shaun and trudy have sold altogether?
Answer:
x/2 + 3
Step-by-step explanation:
Shaun sold x tickets.
Trudy has sold 3 more tickets than half the number of tickets that Shaun sold.
Half the number Shaun sold is x/2.
3 more than that is x/2 + 3
Answer: x/2 + 3
Answer:
x/2 +3 + x
Step-by-step explanation:
Trudy sold x/2 + 3 tickets compared to shaun. So the total number of tickets they sold overall is x/2 +3 + x.

-16+2x= -64 what is the value of x
Answer:
add 16 to both sides so it would 2x=-48 then you would divide 2 on both sides so it would be x=-24
Step-by-step explanation:
X=-24
Answer:
-16 + 2x = -64
+16 +16
2x = -48
-48÷2=-24
x = -24
A shoe store has 23 pairs off white tennis shoes out of 90 pairs of shoes. Estimate the percent of white tennis shoes.
Answer:
percent=25.56%
Step-by-step explanation:
Percentages
To know the percentage of having n elements out of a total of m elements, we calculate the ratio n/m and express the result as a percentage.
The shoe store has 23 pairs of white shoes out of 90 total pairs of shoes. The percent of white tennis shoes is calculated as follows:
[tex]\displaystyle percent= \frac{23}{90}*100\%[/tex]
Operating:
percent=25.56%

x = − 4 , 2 ± 2 √ 3 i
Step-by-step explanation:
find the standard deviation
Answer:
d. 7.3
Step-by-step explanation:
To get the standard deviation of a population of data, first take the sum of all the values, and divide it by the count to get the mean (average).
75 [1] + 90 [2] + 75 [3] + 80 [4] + 90 [5] + 80 [6] + 100 [7] + 85 [8] + 80 [9] + 85 [10] = 840.
Then divide by the count which is 10.
840/10 = 84 [This is the mean of the data.]
Then subtract every point of data from the mean and square it:
(75-84)^2 + (90-84)^2 + (75-84)^2 + (80-84)^2 + (90-84)^2 + (80-84)^2 + (100-84)^2 + (85-84)^2 + (80-84)^2 + (85-84)^2 = 81 + 36 + 81 + 16 + 36 + 16 + 256 + 1 + 16 + 1 = 540.
Then to get the variance, divide this all by the count.
540/10 = 54 [This is the variance of the data.]
Then all you have to do to get the standard deviation is take the square root of the variance.
√54 = 3√6 ≈ 7.3 [This is the standard deviation of the data.]

Suppose you have a total of $2.25 in dimes and
nickels. You have twice as many dimes, as nickels.
Which system of equations could be used to
determine how many of each coin you have?
Answer:
n = number of nickels
2n = number of dimes
n($0.05) + 2n($0.10) = $2.25
0.05n + 0.2n = 2.25
0.25n = 2.25
n = 2.25/0.25 = 9
2n = 2(9) = 18
You has 9 nickels and 18 dimes

Evaluate f(x) = -2x - 5 for x = 3.
A. 11
B. -6
C. -11
D. 1
Answer:
C. -11
Step-by-step explanation:
f(x) = -2x - 5
Plug the 3 in for x
f(3) = -2(3) - 5
Multiply the -2 and 3
f(3) = -6 - 5
Subtract 5 from -6
f(3) = -11
Answer: C -11
Step-by-step explanation:
Its asking you to solve for f(x) which is Y
Y=-2x-5
X is 3
so replace -2x with 3 but only the x
you should get -23 not negative 23 its more of 2 times 3
then multiply -2 by 3 and get -6
add -6 and -5 to get -11

Hats, T-shirts, and jackets are sold at a rock concert. 3 hats, 2 shirts, and one jacket costs $140. Two hats, two shirts, and 2 jackets cost $170. One hat, 3 shirts, and 2 jackets cost $180. Create a system of 3 equations to model the situation. Assume the price of hats is x, shirts is y and jackets is z.
Step-by-step explanation:
3x + 2y + z = 140
2x + 2y + 2z = 170
x + 3y + 2z = 180

Elijah is trying to make extra money on his summer vacation from school. He works two different jobs, earning $8 per hour babysitting and $10 per hour lifeguarding. How much money would Elijah earn in a week in which he worked 3 hours babysitting and 7 hours lifeguarding?
Answer:
$94
Step-by-step explanation:
8x + 10x = y
8 (3) + 10 (7) = y
24 + 70 = y
94 = y
Answer with step-by-step explanation:
If he were to work a full week, then 3 hours babysitting × 7 days a week × $8 for work = $168 for babysitting. 7 hours lifeguarding × 7 days a week × $10 for work = $490 for lifeguarding.
The total amount of money that Elijah would earn is $168 + $490 = $658

15(15b−7)=3b−9 plz help meee
Answer:
B=16over37
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
15(15b−7)=3b−9
(15)(15b)+(15)(−7)=3b+−9(Distribute)
225b+−105=3b+−9
225b−105=3b−9
Step 2: Subtract 3b from both sides.
225b−105−3b=3b−9−3b
222b−105=−9
Step 3: Add 105 to both sides.
222b−105+105=−9+105
222b=96
Step 4: Divide both sides by 222.
222b
