Answer:
The angle is 68.2 degrees
Step-by-step explanation:
Let us have the shorter side as the width
In that case, the opposite will be the length which is 8 cm
The diagonal is the hypotenuse
The short side is the adjacent
The trigonometric ratio that links the opposite and the adjacent is the tan
tan of an angle is the ratio of its opposite to the adjacent
In this case,
tan theta = 8/3.2
theta = arc tan (8/3.2)
theta = 68.2 degrees
What is the slope :( help
Answer:400
Step-by-step explanation
in order to find slope you put the change in y over the change in x, y gains 1200 units while x gains 3 units, this means we get 1200/3 and we can simplify it to 400
Answer:
400
Step-by-step explanation:
We can use the formula [tex]\frac{rise}{run}[/tex] to find slope!
So first we find points on the graph. The first point we see is 600. The second point we see is 1,400. Next, we find the rising distance between 1,400 and 600 which is 800. Now we look at the running distance which is 2. Now we plug it into the [tex]\frac{rise}{run}[/tex] formula.
The formula should now look like this:
[tex]\frac{rise}{run}\\[/tex] = [tex]\frac{800}{2}[/tex]
[tex]\frac{800}{2}[/tex] = 400
So the slope is 400

Kara ran 5 miles yesterday. She ran again today. Her total distance for
both days is 6.5 miles. If she ran at a pace of 6 miles per hour today,
how long did Kara run today?
9514 1404 393
Answer:
15 minutes
Step-by-step explanation:
We can let t represent the time in hours that Kara ran today. Then her distance today is ...
distance = speed · time
distance = 6t
Her total distance for both days is ...
5 + 6t = 6.5
6t = 1.5 . . . . . . . . . . subtract 5
t = 1.5/6 = 1/4 . . . . . divide by 6
Kara ran 1/4 hour today. That is 15 minutes.

The lines shown below are parallel. If the green line has a slope of 5, what is
the slope of the red line?
A: -5
B: 5
C: -1/5
D: 1/5
Answer:
5
Step-by-step explanation:
For two lines to be parallel, they must have the same slope
since the slope of the green line is 5, the the red line will have the same slope as the green line,
The slope of the red line will therefore be 5
Which expression is equivalent to x² - 4x - 45?
А
(x - 9)(x - 5)
B
(x + 9)(x+5)
(20 +9)(x - 5)
D
(x - 9)(x+5)
Answer:
D. (x - 9)(x+5)
Step-by-step explanation:
[tex]x^{2} - 4x - 45[/tex] is your expression, so you have to factor it out. Since from the options available it's clear that the factors of -45 you use are some form of 9 and 5, we can use the process of elimination to figure out which are the correct ones.
First, through FOIL u know that in any factored form the last two terms in each bracket multiply together to make the last term in the expanded form.
So first, look at A. the last two terms are -9 and -5, which = 45 when multiplied together. 45 does not = -45, so it can't be A.
B has 9 and 5. When they're multiplied, they = 45, which does not = -45, so its not B
It can't be C either, because the first term of the first bracket in C is 20, and when multiplied with x it doesn't produce x^2.
Therefore it has to be D. u can check this by multiplying -9 and 5, which = -45, the final term in the expanded form. Also, -9 + 5 = -4, which is the middle term of the expanded form.
The equivalent expression to x² - 4x - 45 is (x - 9)(x + 5), which corresponds to option A.
To factor the quadratic expression x² - 4x - 45, we need to find two binomials that, when multiplied, give us the original expression.
We look for two numbers whose product is -45 (the coefficient of the constant term) and whose sum is -4 (the coefficient of the linear term, -4x). After some exploration, we find that the numbers -9 and 5 satisfy these conditions.
Thus, we can express x² - 4x - 45 as (x - 9)(x + 5). This is because when we multiply the two binomials (x - 9) and (x + 5) using the distributive property, we obtain the original quadratic expression.
This factored form, (x - 9)(x + 5), represents the equivalent expression to x² - 4x - 45.

Denise makes three times as many chocolate cupcakes as vanilla cupcakes. She also makes three dozen strawberry cupcakes. If Denise makes 132 cupcakes, how many dozen chocolate cupcakes does she make?
Answer:
6 dozens
Step-by-step explanation:
Vanilla, v = x
Chocolate, c = 3x
Strawberry, s = 3 dozens = 36
Total cupcakes = 132
Hence,
x + 3x + 36 = 132
4x = 96
x = 96 / 4
x = 24
Chocolate = 3 * 24 = 72
Dozens of chocolate = 72 /12 = 6 dozens

Which of the following best describes interest as it relates to credit?
A. Additional money earned for having an account
B. The limit for which an individual may use credit
C. The charge for the privilege of borrowing money
D. The total amount a borrower must repay a lender for a loan
Answer:
C
Step-by-step explanation:
Let's say you wanted to buy a television. The television cost $200 but you only have $100, so you ask your friend for some money. Your friend says they will give you money but you have to pay them back and pay them interest. So when you go pay them, you pay them $100 dollars along with the amount of money your friend wants you to pay them for borrowing their money. In the end you could end up giving them 120 instead of 100.
C. The charge for the privilege of borrowing money

Answer:
y = 5x - 2
Step-by-step explanation:
The equation at the bottom is already in slope-intercept form, or y = mx + b format. It lacks one missing piece: b, or the y-intercept. However, the slope of the equation must be 5, because the number in place of the m equals the slope.
So, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex], and substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values. From there, we can isolate y to receive the full equation in slope-intercept form.
Since m represents the slope, substitute 5 in its place. Since the [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose any of the points provided and substitute its values into the formula. (Either one is fine, and I chose (1,3).) From there, isolate y to find the slope-intercept form and answer:
[tex]y-(3) = 5 (x-(1))\\y - 3 = 5(x-1)\\y - 3 = 5x -5\\y = 5x - 2[/tex]

Skylar is answering the following math problem: The value of an investment decreased by 10%. The original amount of the investment was $75.00. What is the current value of the investment? Skylar said 10% of $75.00 is $7.50, and since the investment decreased by that amount, you have to subtract $7.50 from $75.00 to arrive at the final answer of $67.50. Create one algebraic equation that can be used to arrive at the final answer of $67.50. Solve the equation to prove it results in an answer of $67.50. Be prepared to explain your thought process to the class.
Answer:
The given parameters of the investment are;
The rate of decrease of the investment, r = -10%
The original amount of the investment, P = $75.00
Let 'A' represent the final answer (value of the investment) after the decrease in the investment, 'r', is applied, we have;
The algebraic equation that can be used to arrive at the final answer, 'A', is given as follows;
A = P + r·P
Therefore by substituting the given values, we have;
A = $75.00 + (-10/100) × $75.00 = $75.00 - 0.1 × $75.00 = $75.00 - $7.50
A = $75.00 - $7.50 = $67.50
The final amount or answer, A = $67.50

Solve the simulataneous equations. 5x-4y=19 x+2y=8
Answer:
(5, 1.5 )
Step-by-step explanation:
Given the 2 equations
5x - 4y = 19 → (1)
x + 2y = 8 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
2x + 4y = 16 → (3)
Add (1) and (3) term by term to eliminate y
7x + 0 = 35
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5 + 2y = 8 ( subtract 5 from both sides )
2y = 3 ( divide both sides by 2 )
y = 1.5
solution is (5, 1.5 )
