Triangle PQR is similar to triangle XYZ
Select all angles that have a cosine of 9/15
Answers
Answer:
Step-by-step explanation:
All the angles that have a cosine of 9/15 are,
⇒ ∠P and ∠X
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Triangle PQR is similar to triangle XYZ.
Hence, We get;
In triangle PQR,
cos P = 9/15
And, In triangle XYZ,
cos X = XZ / ZY
cos X = 9 / 15
Thus, All the angles that have a cosine of 9/15 are,
⇒ ∠P and ∠X

simple, it's (4,4) because the (-4,-4) is on the left side then on the right side, we know the x axis is positive right? so then you know that the bottom of the y axis is negative and the x axis is first in the coordinate and so the first one is positive now.

Does the set of numbers form a Pythagorean triple? Explain.
24, 20, 32
Choose the correct answer below.
No, because the given numbers satisfy the equation a? + b2 = c?
Yes, because the given numbers satisfy the equation a? + b2 = c2.
Yes, because the given numbers do not satisfy the equation a? + b2 =c2.
No, because the given numbers do not satisfy the equation a² + b2 =c2.
Answers
Answer:
D. No, because the given numbers do not satisfy the equation a² + b² = c²
Step-by-step explanation:
For the set of numbers; 24, 20, 32, to form a pythagorean triple, they must satisfy the equation a² + b² = c².
Where, c is the longest side (hypotenuse), while a and b are the two other legs.
Let's find out.
a = 20, b = 24, c = 32
Plug in the value into the equation
20² + 24² = 32²
976 = 1,024 (this is not true).
976 is not equal to 1,024.
The set of given numbers does not form a pythagorean triple because it does not satisfy the equation a² + b² = c².
A store has apples on sale for $7.00 for 2 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $28.00? Complete the explanation.
Answers
Answer:
Approx 24 apples.
Step-by-step explanation:
So, you have $28. 1st find out how much a lb. of apples cost. So divide 7/2 to get $3.50. A pound of apples cost $3.50. After that divide 16oz(1 lb) by 5 oz. to get 3.2. So you can get approx 3 apples for the price of $3.50. With $7 you get 6 apples. For 2 more pounds, that'd be 12 with only $14 spent. For another 2 that'd be 18 with $21 spent. For another 2 that'd be 24 with $28 spent.
Given the equations y = 4x + 5 and y = 4x - 7, what is the relationship

B. Parallel
C. Skew
D. Neither
Answers
Answer:
Parallel
Step-by-step explanation:
Given
[tex]y = 4x + 5[/tex]
[tex]y = 4x - 7[/tex]
Required
Determine the relationship
Both lines are parallel. This is so, because they have the same slope.
The equation of a line is:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
For [tex]y = 4x + 5[/tex]
[tex]m_1= 4[/tex]
For [tex]y = 4x - 7[/tex]
[tex]m_2 = 4[/tex]
By comparison:
[tex]m_1 = m_2 = 4[/tex]
Since both slopes are the same, then the lines are parallel

If the slope of a line is -5 and it passes through the origin, what is the equation that represents
that line?--|
Answers
Answer:
Y=x+-5
Step-by-step explanation:
The equation of line that passes through the slope -5 and through the origin is y=-5x.
Given that, the slope of a line is -5 and it passes through the origin.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Substitute m=-5 and (x, y)=(0, 0) in y=mx+c, we get
0=-5(0)+c
c=0
Put m=-5 and c=0 in y=mx+c, we get
y=-5x
Therefore, the equation of line that passes through the slope -5 and through the origin is y=-5x.

Becca has 115 students. Susana has 8 fewer students than Becca. Erika has 25 more students than Susana. How many students does Susana have? *
Answers
Answer:
Susana will have 107 students.
Step-by-step explanation:
Becca have students = 115
Susana has 8 fewer students than Becca.We can write its as:
Becca has 115 students, so Susana will have 115-8 = 107 students
Because fewer means less than so, 8 less than 115 is 115-8
Erika has 25 more students than Susana.We can write it as:
Susana has 107 students, so Erika will have: 107+25 = 132 students.
because more means we need to add 25 students with number of students in Susana class.
So, Susana will have 107 students.

You have $73.50. You earn additional money mowing the lawn. You decide to purchase some shoes that cost $99.99 and you have $23.51. How much money did you earn mowing the lawn?
Answers
I have gotten 50$ for mowing the lawns. First you would want to subtract $99.99 with how much money you have without the money of mowing the lawn. Then you would have to get the answer of $27.50. Lastly, you would need to add up the money you have left and the money you end with after buying the shoes and get $50. So this means that I got $50 for mowing the lawn.
You earned a total of $50 by mowing the lawn.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is that you have $73.50. You earn additional money mowing the lawn. You decide to purchase some shoes that cost $99.99 and you have $23.51.
Assume that the money you earned by mowing lawn is $x. Then, we can write -
(73.5 + x) - 99.99 = 23.51
x + 73.5 - 99.99 = 23.51
x - 26.49 = 23.51
x = 50
Therefore, you earned a total of $50 by mowing the lawn.

Your dinner check was $50. If you give the waiter a 20% tip, how much did you
spend in all? *
Answers
Answer:
$60 in total
Step-by-step explanation:
You find the amount to give for the tip first:
An easy way of doing percent's is getting 10% of a number. 10% of $50.00 you simply move the decimal to the left one time.
You would end up with $5.00 being 10% of $50.00.
Since you want 20% of $50.00 you would just simply multiply $5.00 (10% of $50.00) by 2. (2 * 10% = 20%).
This gives you $10.00.
By knowing 20% of $50.00 is $10.00 you then want to find the grand total you would have to spend in all so you add $10 to the $50 bill giving you a total of $60.00.
Answer:
60.00
Step-by-step explanation:
so you're doing 50.00 plus another 20% since you/re tipping the waiter which gives you a total of 60.00
