Answer: 171.4\%

Step-by-step explanation:

Given

Time is extended from 28 days to 76 days

The percentage increase is given by

\Rightarrow \dfrac{\text{New-original value}}{\text{original value}}\times 100

Putting values

\Rightarrow \dfrac{76-28}{28}\times 100=\dfrac{48}{28}\times 100\\\\\Rightarrow 171.4\%

Thus, the percentage increase in time is 171.4\%

Answer: The team won 100 games and losses 28 games

Step-by-step explanation:

Let the number of games won denoted by x and the games lost is denoted by y .

Given : A minor league baseball team plays 128 games in a season.

Team won 16 more than three times as many games as they lost.

Then, the system of equations, we have

x+y=128-------(1)\\\\x=3y+16------------(2)

We can rewrite equation (2) as x-3y=16----------------(3)

Now, Eliminate equation (3) from (1), we get

y-(-3y)=128-16\\\\\Rightarrow\ 4y=112\\\\\Rightarrow\ y=\dfrac{112}{4}=28

Substitute the value of y in (2), we get

x=3(28)+16=84+16=100

Hence, the team won 100 games and losses 28 games.

I need help solving problem 11.
Lunna [17]
Since triangle ABC is isosceles, then angles 1 and 9 are congruent.

4x + 3 = 9x - 47

-5x = -50

x = 10

m<1 = 4x + 3 = 40 + 3 = 43

m<1 = m<9 = 43

Triangle DBE is equilateral, so it is also equiangular.

m< 4 = m<5 = m<6 =60

Angles 3 and 8 are supplementary to congruent angles that measure 60 deg, so 180 - 60 = 120, so

m<3 = m<8 = 120

For angles 2 and 7, use the sum of the measures of the angles of a triangle is 180 deg.

m<1 + m<2 + m<3 = 180

43 + m<2 + 120 = 180

m<2 + 163 = 180

m<2 = 17

m<2 = m<7 = 17

It is estimated that the annual cost of driving a certain new car is given by the formula C = 0.37m + 2600 where m represents th
arsen [322]

Answer:

12000-14000 (in miles)

Step-by-step explanation:

We are given that the annual cost of driving a certain car is given by the formula

C=0.37m+2600

Where m=Represents the number of miles driven per year

C=Cost in dollars

We have to find the range of  miles that Jane  can drive her new car.

Range of budgets=$7040-$7780

Substitute C=$7040 in the given formula

7040=0.37m+2600

7040-2600=0.37m

4440=0.37m

m=\frac{4440}{0.37}

m=12000

Substitute C=$7780 in the given formula

7780=0.37m+2600

7780-2600=0.37m

5180=0.37m

m=\frac{5180}{0.37}=14000

The range of miles that Jane can drive her new car=12000-14000

If f(x) = (5x^3 - 4)^4, then what is f '(x)?
vlabodo [156]
You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:

4*(5x^3-4)^3 * 3*5x^2 =

60x^2 (5x^3-4)^3
