Answer:
210 students run track and 98 students play baseball
Step-by-step explanation:
For every 15 students who run track there are 7 students who play baseball
There are 112 more students who run track than play baseball
Let y represent the various groups of students
15 × y= 15y
7 × y= 7y
15y - 7y = 112
8y = 112
Divide both side by the coefficient of y which is 8
8y/8 = 112/8
y= 14
Therefore the number of students that run track is
= 15 × 14
= 210
The number of student that play baseball is
= 7 × 14
= 98
Hence 210 students run track and 98 students play baseball

An iceberg weighs 450,000 pounds. If it loses 0.2% of its weight during the day, what is its new weight at the end of the day?
Answer:
449,100 pounds
Step-by-step explanation:
0.2% in decimal form is 0.002
0.002 (percent lost) * 450,000 (weight) = 900 (pounds lost)
450,000 - 900 = 449,100 pounds

Answer:
5/6
Step-by-step explanation:
The solution of the given fraction is 5/6.
Given that:
Fraction: divided 2/3 by 4/5
To calculate the division of fractions, simply need to multiply the first fraction by the reciprocal of the second fraction.
[tex]\dfrac{2/3}{4/5} =\dfrac{2}{3} \times \dfrac{5}{4}\\\dfrac{2/3}{4/5} =\dfrac{(2 \times5)}{(3 \times4) }\\\dfrac{2/3}{4/5} =10 / 12[/tex]
To simplify the fraction, you can divide both the numerator and the denominator by their greatest common divisor, which is 2:
10 / 12 = 5 / 6
So, 2/3 divided by 4/5 is equal to 5/6.
Hence, the required result is 5/6.

The same amount of principal is invested in different accounts earning the same interest rate.
Which of the following accounts would have the greatest accumulated value at the end of one year?
A.An account eaming no interest
B.An account eaming simple interest
C.An account eaming interest compounded annually
D.An account earming interest compounded daily
Answer:
D.An account earming interest compounded daily
Step-by-step explanation:
An account earning interest compounded daily would have accumulated the greatest value at the end of the year.
Compound interest is interest on interest. In compound interest, the interest is calculated on the principal and interest accrued. This makes the value highest. For the account compounded daily, the interest on interest is taken every day. It has a power of 365. For compound interest accrued annually, the interest compounded yearly. Simple interest is basically on the principal.Answer: D! On edge 2021

The ratio 5:1/7 has a unit rate of 35 true or false
Answer:
True
Step-by-step explanation:
To find the unit rate, what we do is to divide the preceding value in the ratio by the succeeding value in the ratio.
Thus, we have;
5 divided by 1/7
= 5 * 7/1
= 35
This is the unit rate of the given ratio

-2,-7,-12 ,.... is an arithmetic sequence Find the sum of its first 20 terms ?
Given sequence:
-2,-7,-12 ,..
Unknown;
Find the sum of the first 20 terms = ?
Solution:
The sequence is -2,-7,-12 ,..
To find he sum of n-terms of a sequence, we use the expression below;
Sₙ = [tex]\frac{n}{2} (2a + (n-1)d)[/tex]
where n is the number of terms = 20
a is the first term = -2
d is the common difference= -7 - (-)2 = -5
Now input the parameters and solve;
Sₙ = [tex]\frac{20}{2} (2(-2) + (20 - 1) x -5)[/tex]
Sₙ = 10(-4 + -5(19)) = 10(-99) = -990
The sum of the first 20 terms of the sequence is -990

The percent change is approximately 1.5%.
The percent change is approximately 66%.
The percent change is approximately 150%.
Answer:
The percent change is approximately 66%.
Step-by-step explanation:
200 is one-third of 600. In math involving percentages, division comes into play in some ways. Divide 600 by 3, and you get 200. 33% is a third of 100% in mathematics, meaning that 200 is one-third, or 33%, of 600.

Find the length of d in the figure below if a = 8 in., b = 3 in., and c = 4 in. Round your answer to the nearest tenth.
Answer:
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
Step (1)
First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.
So we have :
[tex] {h}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] {h}^{2} = 64 + 9 [/tex]
[tex] {h}^{2} = 73 [/tex]
[tex]h = \sqrt{73} [/tex]
_________________________________
Step (2)
Now we another using of Pythagorean theorem for finding d :
[tex] {d}^{2} = {h}^{2} + {c}^{2} [/tex]
[tex] {d}^{2} = 73 + 16 [/tex]
[tex] {d}^{2} = 89 [/tex]
[tex]d = \sqrt{89} [/tex]
[tex]d = 9.4[/tex]

And we're done.

Answer: 6 cups of ketchup per cup of mustard
Step-by-step explanation:
Given : The recipe calls for 3 cups of ketchup for every [tex]\dfrac12[/tex] cup of mustard.
That means , for [tex]\dfrac12[/tex] cup of mustard. we need 3 cups of ketchup.
By using proportions, if we multiply 2 on both sides ,we get

⇒ for [tex]1[/tex] cup of mustard. we need [tex]6[/tex] cups of ketchup.
Hence, the required rate = 6 cups of ketchup per cup of mustard
The rate in cups of ketchup per cup of mustard is 6.
Given that,
The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard.Based on the above information, the calculation is as follows:
