60,000 is borrowed for 10 years. If the interest on the loan is 49,321.74 , find the monthly payment
Answer:
911.0145
Step-by-step explanation:
60,000 is the initial cost to repay and you add 49,321.74 because of interest
60,000+49,321.74= 109321.74 this is the final cost with interest
you divide by ten because there are ten years and you want it to equal 1 year
109321.74/10= 10932.174 this is the cost per year
last you divide by 12 because thats how many months there are per year
10932.174/12= 911.0145 this is the cost per month

which exponential expression is equal to 2−5·28
Answer:
Impossible
Step-by-step explanation:
Solve the answer 2-5*28 = -138
This would have no answer since an exponential expression can't equal an negative unless it's a negative answer, but in this case, there is no answer that would get you -138.

Work Shown:
Because segment GI is parallel to segment TA, this means triangle VGI is similar to triangle VTA.
From that we can set up the proportion
VG/VT = VI/VA
which breaks down into
VG/(VG+GT) = VI/(VI+IA)
Let's plug in the given values. Let x be the length of segment IA.
Let's solve for x
VG/(VG+GT) = VI/(VI+IA)
72/(72+61) = 95/(95+x)
72/133 = 95/(95+x)
72(95+x) = 133*95 ......... cross multiply
6840+72x = 12635
72x = 12635-6840
72x = 5795
x = 5795/72
x = 80.4861111111111 ......... which is approximate
x = 80.49 ......... rounding to the nearest hundredth
The length of IA is roughly 80.49 units. This is not the final answer. The fact that 80.49 is listed as one of the answer choices seems to imply your teacher put it as a trick answer.
Since we found IA = 80.49, this means,
VA = VI + IA
VA = 95 + 80.49
VA = 175.49
This is the length of segment VA, which is the same as segment AV.
-----------------------------
Here's a slightly similar way to solve:
VT = VG+GT = 72+61 = 133
VG/VT = VI/VA
72/133 = 95/x
72x = 133*95
72x = 12635
x = 12635/72
x = 175.486111111111
x = 175.49 is the approximate length of segment AV.
Solve
2x2 + 3x + 1 = 0
Answer:
it's false
Step-by-step explanation:
Answer:
x= -1 or x= -1/2
Step-by-step explanation:
x = -1, x = -1/2, Solve for x:
2 x^2 + 3 x + 1 = 0
The left hand side factors into a product with two terms:
(x + 1) (2 x + 1) = 0
Split into two equations:
x + 1 = 0 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x = -1
Divide both sides by 2:
x = -1 or x = -1/2
What is the value of p so that the expression 4(5 + n) is equivalent to 4(n + p) ?
Answer:
5
Step-by-step explanation:
4(5+n)=4(n+p)
20+4n=4n+4p
4p=20
p=20/4
p=5
Answer:
the value of p is 5
Step-by-step explanation:
the expression 4(5 + n) is equivalent to 4(n + p)
4(5+n)=4(n+p)
5+n=n+p
n+5=n+p
comparing each other
we get p=5
Mrs. Brown drove 105 miles in 2.5 hours. What was Mrs. Browns speed in miles per hour?
Answer:
42mph.
Step-by-step explanation:
We know that the formula for miles per hour is.
r = d/t
R is our rate or miles per hour.
D is our distance.
T is our time.
In this case our distance is 105 miles.
And our times is 2.5 hours.
Therefore if we substitute them into our formula:
105mi ÷ 2.5hrs = 42mph
Hope this helped!

The radius r of the base of a cone is given by the equation r=(3V/piH)
, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for pi .
Answer:
1 inStep-by-step explanation:
Given the expression to calculate the radius r of the base of a cone is given by the equation
r=(3V/piH)
v is the volume = 5in^3
H = 4in
pi = 3.14
Substitute
r = 3(5)/3.14(4)
r = 15/12.56
r = 1.19
r = 1in to the nearest inch

A high school reports that its students' SAT scores were down by 8% in one year. The next year, however, the test scores rose by 18%. The high school principal announces, "Overall, test scores have improved by 10% over the past two years."
Answer:
B
1.09 is the improvement in scores
Step-by-step explanation:
Here is the remaining part of the question : Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The statement is true because 18 - 10 = 8 and the percentage improvement is given by the difference in the percentages of the increase and decrease. B. The statement is false because the reference values for the decrease and increase are not the same. The true improvement over the past two years is (Simplify your answer. Type an integer or decimal rounded to the nearest hundredth as needed.)
let a = scores
If scores decreased by 8% last year, scores that year was (100 - 8%) = 92% = 0.92
scores last year = 0.92a
If scores increased by 18%. It means the score this year is 0.92a x 1.18 = 1.086a
Improvement in scores 1.09

Evaluate 4^0×x^-5 when x=2 .
Answer:
1/32
Step-by-step explanation:
Anything to the power of 0 is 1.
1*x^-5 (negative power means the reciprocal)
1/2^5 = 1/32
1*1/32=1/32
When x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.
To evaluate the expression 4⁰ × x⁻⁵ when x = 2, we'll substitute the value of x into the expression and perform the necessary calculations.
First, let's evaluate 4⁰. Any number raised to the power of 0 is equal to 1. Therefore, 4⁰ = 1.
Next, let's evaluate x⁻⁵ when x = 2. A negative exponent indicates the reciprocal of the base raised to the positive exponent. So, x⁻⁵ = 1 / x⁵.
Substituting x = 2, we have 1 / 2⁵.
Now, we can simplify the expression:
1 / 2⁵ = 1 / 32 = 0.03125
Therefore, when x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.

Anna ran 10 meters, Bill ran 15 meters, and Chloe ran 20 meters. How many centimeters did the three people run?
Answer:
Anna: 1000cm
Bill: 1500
Chloe: 2000
convert m to cm
Answer:
4500 cm
Step-by-step explanation:
1 meter = 100 cm
10 meters = 1000 cm
15 meters = 1500 cm
20 meters = 2000 cm
1000 + 1500 + 2000 = 4500 cm
Tyrone went to a basketball game and bought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89. Tyrone spent a total of $83.39. Write an equation to find the original cost of the jersey
Answer:
Jersey cost (without discount)= $65
Step-by-step explanation:
First, we need to determine how much he spent on the jersey:
Jersey cost (with discount)= 83.39 - 37.89
Jersey cost (with discount)= $45.5
Now, the original cost of the jersey:
Jersey cost (without discount)= discount cost / (1 - discount)
Jersey cost (without discount)= 45.5 / 0.7
Jersey cost (without discount)= $65
The coorrdinate grids show the cost of different numbers of bookmarks .How many cents do 4 bookmarks cost?
Answer:
54 cents
Step-by-step explanation:
The cost of bookmarks relating to the number of bookmarks is shown in the coordinate grid. x represents the number of bookmarks and y represents the cost of each bookmark in cents.
The equation of a line passing through the points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
From the coordinate grid, it has the points (2, 30) and (7, 90). Therefore, the equation is:
[tex]y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2)\\\\y-30=12x-24\\\\y=12x+6[/tex]
Therefore the cost of 4 bookmarks (x = 4):
y = 12(4) + 6
y = 48 + 6
y = 54 cents
