The accounts payable clerk writes 5 checks every 50 minutes. How many checks will he use in 170 minutes?
Answer:
17
Step-by-step explanation:
5/50= x/170 multiply 5x170 divide that answer by 50. or bc u know that 5x10 = 50 u could divide 170 by 10 and still get 17
Answer:
17
Step-by-step explanation:
17 because they write five checks each 50 minutes so it means that every 10 minutes on the check is created incel I went 50 +50+50 =150 And you can't add another 50 so than in 20 minutes to checks can be made and then so I made the conclusion that there can be 17 checks made
hope this helps :)
Jervane is planning on buying a coffee and several donuts for a road trip. She wants to spend no more than $20 in total. Coffee costs $3 and donuts are $2 each. Write and solve an inequality to determine the maximum number of donuts that Jervane can buy. Be sure to include units on your answer.
Answer:
8
Step-by-step explanation:
Given:
Total money Jervane can spend = $20.
Cost of a coffee = $3.
Cost of a donut = $2.
To find: Maximum number of donuts Jervane can buy.
Solution:
Let the number of donuts she can buy be [tex]x[/tex].
She wants to spend no more than $20 in total.
So,
[tex]3+2x\leq 20[/tex]
[tex]\Rightarrow 2x\leqslant 20-3[/tex]
[tex]\Rightarrow 2x\leqslant 17[/tex]
[tex]\Rightarrow x\leqslant \frac{17}{2}[/tex]
[tex]\Rightarrow x\leqslant 8 \frac{1}{2}[/tex]
As the number of donuts can only be a natural number.
Hence, the maximum number of donuts that Jervane can buy are 8.

what’s the equation?
Answer:
The equation is;
y = 2x^2 -8x + 12
Step-by-step explanation:
The vertex form can be written as;
a(x-h)^2 + k
(h,k) represents the coordinates of the vertex
In this case, we have this as (2,4)
The value of a is positive as the parabola opens up and it is the axis of symmetry
It is the x value that divides the graph into 2
Thus, we have x as = 2
so the equation of the graph will be;
2(x-2)^2 + 4
2(x^2 - 4x + 4) + 4
= 2x^2 -8x + 8 + 4
= 2x^2 -8x + 12

What is the measure of Angle HEG?
Answer:
angle HEG = 12 degrees
Step-by-step explanation:
A line is 180 degrees. Since there is a right angle there, you know that angleHEG and 78 added together is 90degrees
x + 78 = 90 >> subtract 78 from both sides
x = 12
angle HEG = 12 degrees
Answer:
18 degrees
Step-by-step explanation:
There is a little box on the left that indicates both angles together make a 90 degree angle so you just have to do 90 - 78 to get the answer.

Please anyone I’ll mark as a branlist
Answer:
the first option is the answer, r = √6
Step-by-step explanation:
[tex]hypotenuse = \sqrt{opposite {}^{2} + adjacent {}^{2} } [/tex]
hypotenuse = q = √12
adjacent = p = √6
opposite = r
substitute the values into the hypotenuse formula
[tex]q = \sqrt{r {}^{2} + p {}^{2} } [/tex]
[tex] \sqrt{12} = \sqrt{r {}^{2} + ( \sqrt{6} ) {}^{2} } [/tex]
[tex]( \sqrt{12} ) {}^{2} = r {}^{2} +6[/tex]
[tex]12 = r {}^{2} + 6[/tex]
[tex]12 - 6 = r {}^{2} [/tex]
[tex]6 = r {}^{2} [/tex]
[tex] \sqrt{6} = r[/tex]
[tex]r = \sqrt{6} [/tex]

The cost of a t-shirt was $30. Now the t-shirt costs $37.50. What is the percent of change? Do the work on your own paper and write your answer as a number.
Answer:
25%
Step-by-step explanation:
Given that,
Initial cost of a t-shirt = $30
Final cost of a t-shirt = $37.50
We need to find percent of change. The percentage change in any value is given by :
[tex]\%=\dfrac{\text{final value-initial value}}{\text{initial value}}\times 100\\\\=\dfrac{37.5-30}{30}\times 100\\\\=25\%[/tex]
Hence, the percentage error is 25%.
