Answer:
$1105
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 6500 × 0.0425 × 4 = 1105
I = $ 1,105.00
The simple interest accumulated
on a principal of $ 6,500.00
at a rate of 4.25% per year
for 4 years is $ 1,105.00.

If you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Complete question :
Mitch is making birdhouses to sell. He needs to make at least $678. Each birdhouse costs $28 to make. He is selling them for $40 each. What is the minimum he can sell to reach his goal?
Answer:
57
Step-by-step explanation:
you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Target profit = $678
Expenses per product = $28
Income per sale = $40
Profit per sale = $(40 - 28) = $12
Let number of sales or product = x
Hence,
$12 * x ≥ 678
12x ≥ 678
x ≥ 678 / 12
x ≥ 56.5
To the nearest whole number = 57

What is the y-intercept of the trend line, to the nearest hundredth?
Answer:
-23.21
there should be a two part for this and the answer would be D y= 0.15x - 23.21
Step-by-step explanation:
The line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
The data is given:
R(x) W(y)
808 93
768 94
655 66
684 81
637 86
619 75
613 61
609 69
563 55
The line of best fit can be written as:
y = mx + c
Here m is the slope of the line best fit and c is the y-intercept
Putting the values in the formula we get:
m = 0.15
c = -23.21
The line of best fit is:
y = 0.15x - 23.21
Thus, the line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.

In ΔSTU, s = 3.8 inches, t = 9.8 inches and u=9.6 inches. Find the measure of ∠U to the nearest 10th of a degree.
Answer:
m∠U = 75.7°
Step-by-step explanation:
use Law of Cosines:
9.6² = 3.8² + 9.8² - 2(3.8)(9.8)·cos U
92.16 = 14.44 + 96.04 - 74.48·cos U
92.16 = 110.48 - 74.48·cosU
-18.32 = -74.48·cosU
cos U = -18.32/-74.48
cos U = 0.24597
arccos U = 75.7
Answer:
m∠U = 75.7°
Step-by-step explanation:
its on delta and if you use a calculator then its m∠U = 75.7°

rewrite in a simpler equivalent form and solve
Given:
The equation is
[tex]\dfrac{3x}{7}+\dfrac{2}{7}=2[/tex]
To find:
The simpler equivalent form and solve the given equation.
Solution:
We have,
[tex]\dfrac{3x}{7}+\dfrac{2}{7}=2[/tex]
It can be written as
[tex]\dfrac{3x+2}{7}=2[/tex]
Multiply both sides by 7.
[tex]3x+2=14[/tex]
[tex]3x=14-2[/tex]
[tex]3x=12[/tex]
Divide both sides by 3.
[tex]x=\dfrac{12}{3}[/tex]
[tex]x=4[/tex]
Therefore, the simpler equivalent form of the given equation is [tex]3x+2=14[/tex] and the solution is x=4.
Write a function role for the total cost.
One frozen yogurt store sells frozen yogurt for $3.00 per cup and $1.25 per topping. Write a linear equation to show the total cost of a cup of frozen yogurt. Then calculate the total price for one cup of frozen yogurt with 4 toppings.
Answer:
y=1.25x+3, $8.00
Step-by-step explanation:
3 is the variable. A cup of frozen yogurt will always be a set price of $3.00. The toppings are the variable, which will depend on how many the customer adds.
Therefore, the equation would be y=1.25x+3
x being the number of toppings added
If the customer orders one cup of ice cream with 4 toppings, the equation would look like:
y=(1.25*4)+3
y=(5)+3 = $8.00 for a four topping cup of frozen yogurt

What is a word problem?
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Let the two numbers be x and y.
Two numbers have a negative sum, but a positive product.
So, the two numbers are -x and -y.
Let us consider the two numbers be -2 and -3
Sum of two numbers = [tex]-2+(-3)[/tex]
⇒ [tex]-5[/tex]
Product of two numbers = [tex](-2)(-3)[/tex]
⇒ [tex]6[/tex]
Thus the sum have a negative number and the product is a positive product.
Hence we can conclude that the example of her numbers could be -2 and -3.

What is the equation of the line that passes through the point ( -1, 1) and is perpendicular to 2x + 4y = 16?
A. y = −2x − 1
B. y − 3 = 2x
C. y = 6x + 7
D. Cannot be determined
Answer:
B
Step-by-step explanation:
We want the equation of the line that passes through the point (-1, 1) and is perpendicular to:
[tex]2x +4y=16[/tex]
Remember that the slopes of perpendicular lines are negative reciprocals of each other.
So, let's find the slope of the original line first. We can do so by converting it to slope-intercept form. Thus:
[tex]4y=-2x+16[/tex]
Therefore:
[tex]\displaystyle y=-\frac{1}{2}x+4[/tex]
The slope is -1/2.
The negative reciprocal of -1/2 is 2.
Thus, the slope of our new line is 2.
The slope is 2 and it passes through the point (-1, 1).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]y-(1)=2(x-(-1))[/tex]
Distribute:
[tex]y-1=2x+2[/tex]
Subtracting 2 from both sides yields:
[tex]y-3=2x[/tex]
Therefore, our answer is B.
A 12 foot ladder is leaning against a house. The bottom of the ladder is 3 ft from

tenth.
Answer:
h = 11.61 foot
Step-by-step explanation:
Given that,
The length of a ladder, l = 12 foot
The bottom of the ladder is 3 ft from the house.
We need to find how high does the top of the ladder reach. Let it is h. The length of the ladder will be the hypotenuse. 3 ft will be the base. So,
[tex]12^2=3^2+h^2\\\\h^2=144-9\\\\h=11.61\ \text{foot}[/tex]
So, the top of the ladder is at a height of [tex]11.61\ \text{foot}[/tex].

Answer:
23 degrees
Step-by-step explanation:
Find the diagram attached
The sum of angle on the straight line is 180°
103+3x+15+x+10 = 180
128+4x =180
4x = 180-128
4x = 52
x = 52/4
x = 13
The measure of the angle of the intersection between Derby Drive and Rosemont is x+10
= 13+10
= 23 degrees
Hence the measure of the angle is 23 degrees
