A tennis player lands 25 out of 40 first serves in bounds for a success rate of 62.5%. How many more consecutive first serves must she land in bounds to increase her success rate to 70%.
The tennis player must consecutively land 10 more first serves in bounds to raise their success rate from 62.5% to 70%.
First, let's define the variables:
x = number of additional successful serves needed
40 + x = total number of serves after additional successful serves
25 + x = total number of successful serves after additional successful serves
We set up the equation with the desired success rate of 70%:
(25 + x) / (40 + x) = 0.70
To solve this equation, follow these steps:
Multiply both sides by (40 + x):
25 + x = 0.70 * (40 + x)
Distribute 0.70 on the right side:
25 + x = 28 + 0.70x
Isolate the variable x by subtracting 0.70x from both sides:
25 + x - 0.70x = 28
Combine like terms:
0.30x = 3
Solve for x by dividing both sides by 0.30:
x = 10
Thus, the tennis player must land 10 more consecutive first serves in bounds to increase her success rate to 70%.

solve by substitution 3x+2y=-5, 2x-5y=-16
The solution to the system of equations is [tex]\(x = -3\)[/tex] and [tex]\(y = 2\).[/tex]
let's solve the system of equations using the substitution method.
Given:
1. [tex]\(3x + 2y = -5\)[/tex]
2.[tex]\(2x - 5y = -16\)[/tex]
Step 1: Solve one equation for one variable in terms of the other variable.
Let's solve equation 1 for [tex]\(x\):[/tex]
[tex]\[3x = -2y - 5\][/tex]
[tex]\[x = \frac{-2y - 5}{3}\][/tex]
Step 2: Substitute the expression for [tex]\(x\)[/tex]from step 1 into the other equation.
Substitute [tex]\(x = \frac{-2y - 5}{3}\)[/tex] into equation 2:
[tex]\[2\left(\frac{-2y - 5}{3}\right) - 5y = -16\][/tex]
Step 3: Solve for [tex]\(y\).[/tex]
[tex]\[ \frac{-4y - 10}{3} - 5y = -16 \][/tex]
[tex]\[ -4y - 10 - 15y = -48 \][/tex]
[tex]\[ -19y - 10 = -48 \][/tex]
[tex]\[ -19y = -38 \][/tex]
[tex]\[ y = 2 \][/tex]
Step 4: Substitute the value of [tex]\(y\)[/tex] into one of the original equations to solve for [tex]\(x\).[/tex]
Let's use equation 1:
[tex]\[3x + 2(2) = -5\][/tex]
[tex]\[3x + 4 = -5\][/tex]
[tex]\[3x = -9\][/tex]
[tex]\[x = -3\][/tex]

Kite ABCD represents a softball field that is being built. If AC = 48 meters, what is the perimeter of the field? 40 meters 70 meters 140 meters 218 meters
Answer:
140 m
Step-by-step explanation:
A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal in length.
The perimeter of the kite is the sum of the length of all its sides. So, the perimeter of kite ABCD can be expressed as:
[tex]\sf Perimeter = AB + BC + CD + DA[/tex]
As BC = AB and CD = DA, then:
[tex]\sf Perimeter = BC + BC + CD + CD\\\\Perimeter = 2(BC + CD)[/tex]
Therefore, to find the perimeter of kite ABCD, we need to determine the lengths of sides BC and CD.
The diagonals of a kite intersect to form two pairs of congruent right triangles, where the sides of the kite are the hypotenuses of these triangles.
in kite ABCD:
Diagonal AC = 48 mDiagonal BD = 18 + 32 = 50 mThe longer diagonal of a kite always bisects the shorter diagonal at a right angle.
Let M be the point of intersection of the diagonals. Therefore:
AM = MC = 24 m
Side BC is the hypotenuse of right triangle BMC, with legs measuring 18 m and 24 m, while side CD is the hypotenuse of right triangle CMD, with legs measuring 32 m and 24 m.
To find the lengths of sides BC and CD, we can use the Pythagorean Theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the two legs.
[tex]\sf BC^2=18^2+24^2 \\\\BC^2=324+576 \\\\BC^2=900\\\\BC=\sqrt{900}\\\\BC=30\; m[/tex]
[tex]\sf CD^2=32^2+24^2 \\\\CD^2=1024+576 \\\\CD^2=1600\\\\CD=\sqrt{1600}\\\\CD=40\; m[/tex]
Now we have determined the length of sides BC and CD, we can substitute them into the perimeter formula:
[tex]\sf Perimeter = 2(30+40) \\\\ Perimeter = 2(70) \\\\ Perimeter = 140 \; m[/tex]
Therefore, the perimeter of kite ABCD is:
[tex]\LARGE\boxed{\boxed{\sf 140\; m}}[/tex]

The balance on Brent Tyson’s Discover card on December 1 is $205.84.
In December, he charges an additional $98.42 of purchases, has returns of $18.63, and makes a payment of $25.
If the finance charges are calculated at 1.5% per month on the unpaid balance, find the new balance on January 1.
To find the new balance on January 1, we need to calculate the total balance after considering purchases, returns, payments, and finance charges.
Calculate the total charges:
Total charges = Previous balance + New purchases − Returns
Total charges = $205.84 + $98.42 − $18.63
Total charges = $285.63
After the payment, ascertain the extra amount due:
Unpaid balance = Total charges − Payment
Unpaid balance = $285.63 − $25
Unpaid balance = $260.63
Calculate the finance charges:
Finance charges=Unpaid balance×Monthly interest rate
Monthly interest rate = 1.5% = 0.015
Finance charges = $260.63 × 0.015
Finance charges ≈ $3.91
Calculate the new balance:
New balance = Unpaid balance + Finance charges
New balance = $260.63 + $3.91
New balance = $264.54
So, the new balance on January 1 is approximately $264.54.
To calculate Brent Tyson's new balance on January 1, we first determine the total charges by adding new purchases and subtracting returns from the previous balance.
Then, we deduct his payment to find the unpaid balance.
Next, we calculate finance charges at a rate of 1.5% per month on the unpaid balance.
Finally, we add the finance charges to the unpaid balance to get the new balance.
After these steps, Brent Tyson's new balance on January 1 is $264.54.
This process ensures we account for all transactions and interest charges to accurately determine the updated balance on his Discover card.

Adam charges 20$ to mow his neighbor's lawn every 2 weeks for the 18 weeks of grass growing season. he wants to but a new
Since Adam's expenses exceed his earnings, he will have a negative net earnings. Therefore, Adam will not earn any money this season. In fact, he will have a net loss of $7.50.
To calculate how much Adam will earn this season, subtract his expenses from his total earnings.
Earnings per mowing session: $20
Number of mowing sessions in the grass-growing season: 18 weeks / 2 weeks = 9 sessions
Total earnings: $20 per session * 9 sessions = $180
Expenses:
Cost of the lawn mower: $165
Cost of gasoline per session: $2.50 per session * 9 sessions = $22.50
Total expenses: $165 + $22.50 = $187.50
To find Adam's net earnings, subtract his expenses from his total earnings:
Net earnings = Total earnings - Total expenses
Net earnings = $180 - $187.50
Net earnings = -$7.50
Since Adam's expenses exceed his earnings, he will have a negative net earnings. Therefore, Adam will not earn any money this season. In fact, he will have a net loss of $7.50.

The function f(x)=2^x and g(x)=f(x)+k.If k=-5,what can be concluded about the graph of g(x)?
the graph of g(x) is shifted horizontally
a.5 units to the left of the graph of f(x)
b. 5 units to the right of the graph of f(x)
c.the graph is not shifted horizontally from the graph of f(x)
The graph of g(x) will be the same as the graph of f(x) shifted vertically downwards by 5 units because k=-5 represents a vertical shift, not a horizontal one. There is no horizontal shift involved.
When considering the functions [tex]f(x)=2^x[/tex]and g(x)=f(x)+k, with k=-5, we look at how the graph of g(x) compares to the graph of f(x).
Since the value of k is negative, it implies that a constant is being subtracted from the function f(x). This means that the graph of g(x) will not be shifted horizontally, but rather vertically downwards by 5 units.
Therefore, option c is the correct answer: the graph is not shifted horizontally from the graph of f(x).

A person whose eye level is 1.5 meters above the ground is standing 75 meters from the base of the jin mao building in shanghai, china. the person estimates the angle of elevation to the top of the building is about 80º. what is the approximate height of the building
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The height of the building from the ground is 426.85 meters.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
As it is given that the angle of elevation from the person's view is 80°, while the distance between the person and the base of the building is 75 meters, therefore, using the trigonometric function the height of the building top from the person eye level is,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\Tan(80^o) = \dfrac{\text{Height of the building}}{75\ meters}\\\\\\\text{Height of the building} = 75 \times tan(80^o) = 425.35\ meters[/tex]
Now, we know the height of the building top from a person's eye level, and we also know the person's eye level as well, therefore, the height of the building can be written as,
[tex]\text{Height of the building} = 425.35 + 1.5 = 426.85\rm\ meters[/tex]
Hence, the height of the building from the ground is 426.85 meters.

Amy volunteers at an animal shelter. She worked 10 hours in March, 12 hours in April, 14 hours in May, and 16 hours in June. If the pattern continues, how many hours will she work in December?
By continuing the pattern of Amy increasing her volunteer hours by 2 each month, she will work for 30 hours in December.
Explanation:To find out how many hours Amy will work in December, we must first identify the number of terms between June and December.
Counting inclusively, we see that there are seven months between June and December (June, July, August, September, October, November, December), which means we should look for the 7th term after June to find the number of hours Amy will work in December.
Since we have established an increase of 2 hours each month, we can calculate this by adding 7 terms of an arithmetic progression to Amy's last known volunteering hours.
To do this, we use the explicit formula for an arithmetic sequence:
Tn = a + (n - 1) * d,
where Tn is the term we wish to find, a is the first term in the sequence, n is the position of the term in the sequence, and d is the common difference between terms. Amy's last known volunteering hours in June (the 4th term in the sequence) were 16, with a common difference of 2.
Adding 7 intervals of 2 hours each gives us 14 additional hours by December.
Therefore, we add this to the 16 hours she worked in June: 16 + 14 = 30 hours.
Amy is expected to volunteer for 30 hours in December.
