The amount in Kelly's account at the end of four years will be $887.63.
Explanation:To calculate the amount in Kelly's account at the end of four years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, Kelly's principal amount is $750, the annual interest rate is 4.25%, and interest is compounded semi-annually, so n = 2. Plugging these values into the formula:
A = 750(1 + 0.0425/2)^(2*4)
A = 750(1 + 0.02125)^8
A = 750(1.02125)^8
A = 750(1.18350595645)
A = $887.63

A reasonable estimate for 597 x 52 is
Answer: 30,000
Step-by-step explanation: Round 597 to nearest hundred and 52 to nearest ten.
Final answer:
To estimate 597 x 52, round 597 to 600 and 52 to 50, then multiply to get 600 x 50 = 30,000. Therefore, a reasonable estimate is 30,000.
Explanation:
The student has asked for a reasonable estimate for 597 x 52. To provide an estimate, we can round numbers to simplify the multiplication. In this case, we can round 597 to 600 and 52 to 50. Now, let's multiply these rounded numbers.
First, multiply 6 by 50, which equals 300.Then, since we rounded up to the hundreds, we recall that 600 is 10 times greater than 60, so we must multiply 300 by 10, which equals 3000.Therefore, a reasonable estimate for 597 x 52 is 30,000.

a television with a 5:4 screen shows an image with a ratio of 20:12 which creates a letter boxed image. What percent of the screen area is occupied
Answer: [tex]75\%[/tex]
Step-by-step explanation:
You know that the ratio of the television's screen is [tex]5:4[/tex] . This ratio can be also written as the following fraction:
[tex]\frac{5}{4}[/tex]
The television shows an image with a ratio of [tex]20:12[/tex] which can be also written as a fraction:
[tex]\frac{20}{12}[/tex]
Set up the following proportion and solve for "x":
[tex]\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16[/tex]
Now, in order to find the percent of the screen area occupied make the following division:
[tex]\% occupied=\frac{12}{16}*100=75\%[/tex]

Malik stops at the grocery store to buy a bag of diapers and 2 cans of formula. He spends a total of $37. The next week he stops and buys 2 bags of diapers and 5 cans of formula for a total of $87. How much does a bag of diapers cost? How much is one can of formula?
Answer:
The cost of one bag of diapers is $11 and the cost of one can of formula is $13
Step-by-step explanation:
Let
x -----> the cost of one bag of diapers
y ----> the cost of one can of formula
we know that
[tex]x+2y=37[/tex] -----> equation A
[tex]2x+5y=87[/tex] ----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (11,13)
see the attached figure
therefore
The cost of one bag of diapers is $11 and the cost of one can of formula is $13
Final answer:
The cost of one bag of diapers is $11, and the cost of one can of formula is $13, as determined by solving a system of two linear equations that describe Malik's purchases.
Explanation:
The student is presented with a system of linear equations based on the purchases made by Malik at different times. The purchases involve a bag of diapers and cans of formula, with the total amounts spent being provided. This information can be turned into a system of equations to solve for the price of one bag of diapers and the price of one can of formula.
Let D represent the cost of one bag of diapers and F represent the cost of one can of formula. From the given information, we can construct the following equations:
D + 2F = $37 (Equation 1: One bag of diapers and two cans of formula cost $37)
2D + 5F = $87 (Equation 2: Two bags of diapers and five cans of formula cost $87)
Now, let's solve this system of equations using the method of substitution or elimination. For simplicity, let's use the elimination method:
Multiply Equation 1 by 2, so it can be arranged to eliminate D:
2D + 4F = $74
Subtract Equation 1 modified from Equation 2:
(2D + 5F) - (2D + 4F) = $87 - $74,
which simplifies to F = $13.
Now plug the value of F back into Equation 1:
D + 2($13) = $37,
D + $26 = $37,
therefore D = $37 - $26,
D = $11.
Therefore, the cost of a bag of diapers is $11, and the cost of one can of formula is $13.

Answer:
This answer is 8
Step-by-step explanation:
It actually is very simple. For this question you do not even need the g(x) equation to continue, so put it aside for now. F(x) means that whatever number that will take the place of x will be used in this equation. If f(x)=3x-1, then f(3)=3(3)-1
This happens because the 3 in f(3 tells you to substitute x for 3 in the equation. ) So just plug in 3 for x and solve to get the answer 8.

Can you draw two triangles each having two 45° angles and one. 90° angle that are not similar justify her answer
No, you cannot draw two triangles each having two 45° angles and one 90° angle that are not similar. All 45-45-90 triangles are similar by definition because they have the same shape, i.e., their angles are the same (two 45° angles and one 90° angle). These similar figures can differ in size, but not in shape.
Explanation:No, it is not possible to draw two triangles each having two 45° angles and one 90° angle that are not similar. Let's break this down.
All triangles that have two 45° angles and one 90° angle are called 45-45-90 triangles. In a 45-45-90 triangle, the angles are always the same, so they are always similar by the definition of similar figures. Similar figures have the same shape, but not necessarily the same size. Their corresponding angles are congruent (the same) and their corresponding sides are in proportion.
Since all 45-45-90 triangles have the same angles - two 45° angles and one 90° angle - they are all similar to each other, regardless of their size. The size of the triangle does not matter, because the definition of similar figures is based on the shape, not the size. Hence, it is impossible to draw two 45-45-90 triangles that are not similar.

Circle Q is shown. Secant L N and tangent P N intersect at point N outside of the circle. Secant L N intersects the circle at point M. Arc M P is y, arc L P is x, and arc M L is z.
Which equation is correct regarding the measure of ∠MNP?
m∠MNP = One-half(x – y)
m∠MNP = One-half(x + y)
m∠MNP = One-half(z + y)
m∠MNP = One-half(z – y)
Answer: FIRST OPTION.
Step-by-step explanation:
By definition, the "Angle formed by a Tangent and a Secant" is:
[tex]Angle\ formed\ by\ Tangent\ and\ Secant=\frac{1}{2}({Difference\ of\ Intercepted\ Arcs)[/tex]
In this case you can identify in the figure that the Intercepted Arcs are:
[tex]LP=x[/tex] and [tex]PM=y[/tex]
And the Angle formed by the tangent and the secant is:
[tex]\angle MNP[/tex]
Therefore, the following equation can be used to calculate the measure of the angle ∠MNP:
[tex]m\angle MNP=\frac{1}{2}(LP-PM)\\\\m\angle MNP=\frac{1}{2}(x-y)[/tex]
This matches with the First option.

HELP ASAP PLZ !! Is triangle MNP a dilation of triangle JKL? Explain why or why not.
To confirm if triangle MNP is a dilation of triangle JKL, one must examine the ratios of the corresponding sides. In a dilation, a figure's size changes but its shape and the angles between its sides remain the same, and the lengths of the sides remain proportional. Without the specific measurements, it's not possible to definitively say if MNP is indeed a dilation of JKL.
Explanation:To determine if triangle MNP is a dilation of triangle JKL, we need to examine the ratios of the corresponding sides. Dilation in mathematics is a transformation that alters the size of a figure without changing its shape or the angles between its sides. In a dilation, the lengths of the sides are proportional.
For example, if triangle MNP has sides that are twice as long as the corresponding sides of triangle JKL, then MNP is a dilation of JKL by a factor of 2.
If the sides of triangle MNP do not maintain the same proportionality with triangle JKL, then triangle MNP is not a dilation of triangle JKL. Therefore, without concrete values or further details, it's difficult to definitively answer whether MNP is a dilation of JKL.

To find the value of 'x' for h(x) = -7 in the function h(x) = x - 5, you would solve the equation for 'x' which results in x = -2.
Explanation:To find the value of 'x' when h(x) = -7 for the function h(x) = x - 5, you have to solve the equation for 'x'. This involves setting the function equal to -7, and then solving for x. Here are the steps:
Set up the equation: h(x) = -7 => x - 5 = -7 Add 5 to both sides of the equation to isolate the variable 'x': x = -7 + 5 Solve the equation: x = -2
So, the value of x for which h(x) = -7 in the function h(x) = x - 5 is -2.
