What is the image point of (3, 8) after a translation right 3 units and down 5 units
Answer:
(6, 3)Step-by-step explanation:
Translation right (or left) means change of the x-coordinate.
Translation down (or up) means change of the y-coordinate.
(3, 8) → (3+3, 8-5) = (6, 3)
Ben deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Ben leaves the money in the account for 12 years, how much interest will he earn?
Answer:
$2,184
Step-by-step explanation:
$6,500 x 2.8% = annual interest
6,500 x 2.8% = $182 annual interest
$182 x 12 years = interest earned in 12 years.
182 x 12 = $2,184

the points on the graphs represent relations. Classify these relations according to whether or not they are functions
9514 1404 393
Answer:
functions: 2 graphs on the rightnot functions: 2 graphs on the leftStep-by-step explanation:
If a vertical line can be drawn that goes through 2 or more points on the graph, then it is not a function. That will be the case for the two graphs on the left side of your figure.
The two graphs on the right side pass this "vertical line test," so are functional relationships.
upper left: not a function
upper right: is a function
lower left: not a function
lower right: is a function

An environment group invited 450 people to a fundraising event .315 people accepted the invention. What percent of the people accepted the invitation
Given:
Total number of invited people = 450
Total number of people who accept the invitation = 315
To find:
The percent of the people who accepted the invitation.
Solution:
We need to find 315 is what percent of 450.
[tex]\%=\dfrac{\text{Number of invited people - Who accept the invitation}}{\text{Number of invited people}}\times 100[/tex]
[tex]\%=\dfrac{450-315}{450}\times 100[/tex]
[tex]\%=\dfrac{135}{45}\times 10[/tex]
[tex]\%=3\times 10[/tex]
[tex]\%=30[/tex]
Therefore, 30% of the people accepted the invitation.

7/8 = 21/k whats k
Answer:
k = 24
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define
7/8 = 21/k
Step 2: Solve for k
Cross-multiply: 7k = 168Divide both sides by 7: k = 24Step 3: Check
Plug in k to verify it's a solution.
Substitute: 7/8 = 21/24Simplify: 7/8 = 7/8Here we see that 7/8 does indeed equal 7/8. ∴ k = 24 is a solution.

Alex is making chocolate cakes. For each cup of milk he uses, he needs to use 1/2 cups of flour. For each
cup of flour he uses, he needs to use 1/3 cup of cocoa powder. Alex is making enough cakes that he needs
to use 4 cups of milk. How many cups of cocoa powder does Alex need to use?
answer: 2/3 (or 0.67) cups of cocoa
Step-by-step explanation: since you need to use 1/2 cups of flour for each cup of milk you divide 4 by 2 and you get 2 then you multiply 2 by 1/3 to get your answer

How does the average travel time for New Yorkers compare to the United States?
a.) 14.5 minutes longer
b.) 14.5 minutes shorter
c.) 4.8 minutes longer
d.) 10.4 minutes longer
Answer:
a) 14.5 minutes longerStep-by-step explanation:
Average time for New York = 40 minutesAverage time for United States = 25.5 minutesThe difference:
40 - 25.5 = 14.5 minutesCorrect choice:
a) 14.5 minutes longerAnswer:
a.) 14.5 minutes longer
Step-by-step explanation:
the average travel time for New Yorkers compare to the United States
= 40.0 - 25.5
= 14.5 min. longer

Answer:
y= -6/5x -3
Step-by-step explanation:
So for now lets bring it into mx + b format
Subtract 6x from both sides to isolate y which is also called subtraction property of equality.
so 5y = -6x -15
Now you divide both sides by 5 which is called division property of equality.
You now have y = -6/5x - 3
y= -6/5x -3 is the slope intercept form of the standard form equation of 6x + 5y = -15.
Hope this helps!

quadrilateral ABCD is inscribed in circle E. the m<A=152 find m<C
Answer:
The angle for C is 28°.
Step-by-step explanation:
In a cyclic quadrilateral, opposite angles are supplementary which means that both angles add up will be 180° :
∠A + ∠C = 180°
152° + ∠C = 180°
∠C = 180° - 152°
∠C = 28°
Answer:
B. 28
Step-by-step explanation:
The answer above me is right, I used their answer on my question earlier and I ended up getting the question right. Hope this helps!
