Lances goal is to run 16 laps around the track. Each lap is 350 yards. Currently lances ran 2450 yards around the track. How much is his percent did he run so far??
Answers
Answer:
Hi There!
Your answer is :
He ran 43.75% so far.
Step-by-step explanation:
16 laps = GOAL
350* 16 to determine goal yards
16laps = 5,600yrds
1 lap= 350 yrds
xlaps = 2450 yrds
2450/350 to determine x laps.
7 laps = 2450 yards
He is 2450 yards into his 5,600 yard goal.
IF 5,600 = 100%
/5600
1 yard = 1/56th %
* 2450
2450yards = 43.75%

Answer:
3x+7=10x-22
We simplify the equation to the form, which is simple to understand
3x+7=10x-22
We move all terms containing x to the left and all other terms to the right.
+3x-10x=-22-7
We simplify left and right side of the equation.
-7x=-29
We divide both sides of the equation by -7 to get x.

If the surface area of a cylinder is 800 in^2 and the height is 15 in, what is the base?
Answers
Answer:
base = diameter
Step-by-step explanation:
if the surface area of the cylinder is 800...
the height is 15... then the formula must be 3.14 x 15 x R2
r squared is supposed to be the square of the radius of the cylinder\
conclusion: 3.14 x 15 x R2 is 800_
so.multiply then..find the radius and add the answer you get to find the diameter ..Andrew brings juice for lunch every 5 days and Hannah brings juice every 7 days they both brought juice today . How many day will it be before they both bring juice ?
Answers
Answer:
35 days
Step-by-step explanation:
Andrew brings juice for lunch every 5 days and Hannah brings juice every 7 days
Find the lowest common multiple of 5 and 7
Andrew (every 5 days) = 10, 15, 20, 25, 30, 35, 40, 45, 50
Hannah (every 7 days) = 14, 21, 28, 35, 42, 49, 56
The lowest common multiple of 5 and 7 is 35
Therefore, if Andrew and Hannah both brought juice today, it will take 35 days before they will both bring food again on the same day.

If _A = 28°, what must the measure of D be in order for A ABC to be similar
to A DEF?
A. 14
B. 28
C. 31
D. 62°
Answers
Answer:
62°
Step-by-step explanation:
If it is a right triangle, subtract 90, from 180 and then subtract 28 to get D. D should = 62°
D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.
The correct answer is option B.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We know that if two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar.
Since angle A is congruent to angle D, we need to find the value of D that makes this true.
Therefore,
D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.

Assume you have applied for two scholarships, a Merit scholarship (M) and an Athletic scholarship (A). The probability that you receive an Athletic scholarship is 0.18. The probability of receiving both scholarships is 0.11. The probability of getting at least one of the scholarships is 0.3. Let M denote the event that you will receive a Merit scholarship. Let A denote the event that you will receive an Athletic scholarship. Answer questions 11-15. What is the probability that you will receive a Merit scholarship
Answers
Answer:
The probability of obtaining a Merit Scholarship = 0.23
Step-by-step explanation:
From the given information:
The probability of obtaining a merit scholarship P(A) = 0.18
The probability of obtaining both P(A ∩ M) = 0.11
The probability of getting at least one P(A ∪ M) = 0.3
The objective is to determine the probability of obtaining a Merit Scholarship.
So, as given:
if M represents Merit Scholarship and A represent Athletic Scholarship,
the probability of obtaining a Merit Scholarship is as follows;
P(M) = P(A ∪ M) + P(A ∩ M) - P(A)
P(M) = 0.3 + 0.11 - 0.18 = 0.23
P(M) = 0.23

There are 52 contacts in your phone. The only family members' numbers you have are your dad's, mom's, and brother's. What are the odds of selecting a number in your phone that is not your family? Write your answer as 1:2 which is reduced as much as possible.
Answers
Answer:
49:52
Step-by-step explanation:
Given that:
Total number of contacts on phone = 52

A group of 12 students is deciding whether to go to the science center or the zoo. Science center tickets are 3 for $36.75 and zoo tickets are 4 for $51.
How much will a group of 12 students save by choosing the science center?
Enter your answer in the box.
Answers
ANSWER:
$6
ExPLANATION:
Step 1:
36.75 × 4 = 147
Step 2:
51 × 3 = 153
Step 3:
153 - 147 = 6
The group of 12 students will save $6 by visiting the science center instead of the Zoo.
Science center fee :
3 tickets = $36.75 Total cost of visiting Science center = (12/3) × 36.75 = $147Zoo Fee :
4 tickets = $51Total cost of visiting Zoo = (12/4) × 51 = $153The difference in the total amount spent :
Total cost of Zoo - Total cost of Science center $153 - $147 = $6Therefore, the group will save $6 by visiting the science center.

1. In the graph it shows a negative slope so we can immediately eliminate a and c since they have a positive slope as shown in the equation. Then the initial value is the y coordinate when x is 0. In the graph you can see that when x is 0 y is 18 so the equation would be h= -3+18
2. In the problem it says that Jennifer is paid $2,200 as a base salary. This means that this is her initial value. Then you can see that she gets paid 300 extra for every car she sales. This is the rate of change. The equation will be y=300x+2,200
fyi 300 goes first because it is the rate of change and those always go first.
