You drive 150 miles in 3 hours. At this rate how far would you travel in 7 hours
Answer:
350 miles in 7 hours
Step-by-step explanation:
If you drive 150 miles in 3 hours, you need to find the "base" meaning how many miles you can go to by 1 hour. To do that you divide 150 with 3 Which equals to 50. So in 1 hour you can travel up to 50 miles. But we need to find how many miles you can go by 7 hours. For that you multiply 50 with 7.
Therefore the answer is 350 miles.

if y varies directly with x and y=60 when x =15 find k and write an equation of direct variation
Answer:
k=45
equation: y=x+45
Step-by-step explanation:
60=15+k
substract 15 on both sides to get 45=k
find the value of X
Answer:
x = [tex]\frac{91}{6}[/tex]
Step-by-step explanation:
Given 2 intersecting chords in a circle, then
The product of the parts of 1 chord is equal to the product of the parts of the other chord, that is
6x = 7 × 13 = 91 ( divide both sides by 6 )
x = [tex]\frac{91}{6}[/tex]

Answer:
37+23
Step-by-step explanation:
I searched it up. someone else asked the exact same question. I hope it's correct though.
Answer:
The larger number is 37 and the smaller number is 14.
Step-by-step explanation:
Let's solve this problem in terms of x and y:
x+y=60
x-y=14
x will be the larger number while y will be the smaller number.
When we add both those equations together, we get 2x=74 since y-y=0. Now we do 74÷2 which equals 37 so x=37. Finally we know that x=37 so our y must be the remaining part since x+y=60. We simply subtract 37 from 60 and get our smaller number, 23.
I hope this helps :)
Kate conducts a survey at her middle school to determine the students' favorite sport. Which sampling method would best produce a representative sample of the population?
Incomplete question. The missing options read;
a. Kate surveys every 8th student from a roster of the choir members.
b. Kate surveys the football team.
c. Kate surveys seventh-grade students.
d. Kate surveys every 4th student entering the school.
Answer:
d. Kate surveys every 4th student entering the school.
Step-by-step explanation:
Interestingly, after careful examination of all the listed sampling methods, none except option d would best produce a representative sample of the population.
This is because;
in the first, second, and third option, none of them evenly represents the entire school population; meaning it fails to produce a representative sample of the population.
However, if Kate surveys every 4th student entering the school, then chances of getting a representative sample of the entire school population are very likely; as different grade level students would likely be entering into the school when the survey activity is taking place.
What is the measure of <C? Round your answer to the nearest tenth of a degree.
A 73.4
B 74.1
C 106.6
D 100.7
Given:
In triangle [tex]ABC, AB=9,BC=4,AC=7[/tex].
To find:
The measure of angle C.
Solution:
We have, [tex]AB=9,BC=4,AC=7[/tex]. It means [tex]c=9,a=4,b=7[/tex].
According to the law of cosines:
[tex]cos C=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
[tex]cos C=\dfrac{4^2+7^2-9^2}{2(4)(7)}[/tex]
[tex]cos C=\dfrac{16+49-81}{56}[/tex]
[tex]cos C=\dfrac{-16}{56}[/tex]
Taking cos inverse on both sides, we get
[tex]C=cos^{-1} \dfrac{-16}{56}[/tex]
[tex]C=106.60155[/tex]
[tex]C\approx 106.6[/tex]
Therefore, the correct option is C.
A water tank holds 24,000 gallons. How many ours will it take for 2/3 of water to be used if the water if the water is used at an average rate of 650 gallons per day
Answer: 591 hours
Step-by-step explanation:
First find out what 2/3 of the water is:
= 2/3 * 24,000
= 16,000 gallons
650 gallons are used per day so the time it takes in days to use the above is:
= 16,000 / 650
= 24.62 days
There are 24 hours in a day. The amount of time it will take to use this amount of water in hours is:
= 24.62 * 24
= 590.88
= 591 hours
The diagram shows a field ABC.
AC = 240 m
Use the sine rule to calculate AB.
Answer:
AB ≈ 312.1 m
Step-by-step explanation:
Using the Sine rule in the triangle, then
[tex]\frac{AB}{sin85}[/tex] = [tex]\frac{240}{sin50}[/tex] ( cross- multiply )
AB × sin50° = 240 × sin85° ( divide both sides by sin50° )
AB = [tex]\frac{240sin85}{sin50}[/tex] ≈ 312.1 m ( to 1 dec. place )

Solve the system of equations by substitution.
-5x + y = 3
7.5x - 1.5y = 3
Answer:
the answer is no solutions
Step-by-step explanation:
What are the values of x and y, in the given figure?
I'll give brailiest to the first response
Answer:
y = 52
x = 5
Step-by-step explanation:
Side BC and Side BA are congruent sides ( indicated by the two dashed lines. )
This meaning that their opposite angles are also congruent
Side BC's opposite angle is ∠A and side BA's opposite angle is ∠C
Hence ∠A ≅ ∠C
And because ∠A = 52°, ∠C also equals 52°
Hence y = 52°
Now we want to find x
We can do this by creating an equation using the triangle angle rule which states that the angles in a triangle add up to equal 180
so...
180 = 14x + 6 + 52 + 52
now we solve for x
step 1 combine like terms
52 + 52 + 6 = 110
now we have 180 = 110 + 14x
step 2 subtract 110 from each side
180 - 110 = 70
110 - 110 cancels out
now we have 70 = 14x
step 3 divide each side by 14
14x/14 = x
70 / 14 = 5
we're left with x = 5

Alright, so first we should add up all of the teachers to get the gist of how many there are in each school.
I got 50 in both North MS and West MS.
F. Half of the teachers would be 25. music+cooking=25 teachers. Correct.
But now, we need to find percentages.
Convert the problem to an equation using the percentage formula: P% * X = Y.
30%x50= 15. Does 9+6 equal 15? Yes, F is Correct.
G. A quarter of 50 is 12.5. (There can't be decimals of teachers though.) At West MS 11 teachers enjoy reading and 14 enjoy outdoor recreation. 11 is less than 12.5 and 14 is more. Incorrect.
H. A majority means more than half in simple terms. Do more than half of the teachers at North MS enjoy rec and cooking? (6+19) It's tricky as there's 25 teachers. However, it is not greater than 25 so it is not a majority. Incorrect.
J. Less than half of 50 teachers at West MS enjoy rec and music. (14+15=29)
Incorrect.
Hope this helped! Khan Academy is a fantastic resource.
Answer:
F.) Half of the teachers at West MS enjoy cooking and music, while only 30% of the teachers at North MS enjoy cooking and music.

The sum of 3 consecutive odd number is 53 What is the second number in the sequence
Answer:
Step-by-step explanation:
Let
x = first odd number
x + 2 = second odd number
x + 4 = third odd number
Total = 53
53 = x + (x + 2) + (x + 4)
53 = x + x + 2 + x + 4
53 = 3x + 6
53 - 6 = 3x
47 = 3x
x = 47/3
x = 15.7
x + 2 = second odd number
15.7 + 2 = 17.7
Second number = 17.7

$103.72
What are the possible numbers of minutes she has used her phone in a month?
Usem for the number of minutes, and solve your inequality for m.
DO
Answer:
1312.5 minutes
Step-by-step explanation:
For her phone service, Lucy pays a monthly fee of $25, and she pays an additional $0.06 per minute of use. The least she has been charged in a month Is $103.72
What are the possible numbers of minutes she has used her phone in a month?
Use m for the number of minutes, and solve your inequality for m.
The term least = ≥ = greater than or equal to
Our inequality equation is given as:
$25 + $0.06 × m ≥ $103.72
25 + 0.06m ≥ 103.72
0.06m ≥ 103.72 - 25
0.06m≥ 78.75
m ≥ 78.75/0.06
m ≥ 1312.5 minutes
The possible number of minutes she used is 1312.5 minutes
