Answer:
2.7 mpg less than Evan's
Step-by-step explanation:
Riley gets 430.1 / 11 = 39.1 mpg
Evan gets 418 / 10 = 41.8 mpg
41.8 - 39.1 = 2.7
9514 1404 393
Answer:
2.7, less
Step-by-step explanation:
To find miles per gallon (MPG), divide miles by gallons.
Riley's car:
(430.1 mi)/(11 gal) = 39.1 mi/gal
Evan's car:
(418 mi)/(10 gal) = 41.8 mi/gal
__
Then the difference is ...
41.8 -39.1 = 2.7 . . . miles per gallon
We note that Riley's MPG is less than Evan's, so we can write ...
Riley's car gets 2.7 miles per gallon less than Evan's car.
Which represents a function?
Answer:
[tex] \boxed{ \text{Option \: D}}[/tex]
Step-by-step explanation:
All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called vertical line test.
If the vertical line intersects the graph of a relation at one point , the relation is a function .If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.--------------------------------------------------
Let's check all of the options :
☐ Option A :
The vertical line cuts the graph at two points. So , the graph does not represent a function.☐ Option B
No! This is also not a function as the vertical line cuts the graph at two points.☐ Option C
Nah! This too can't be called a function as the vertical line cuts the graph at two points.☑ Option D
Yep! The vertical line cuts the graph at one point. Thus , the graph represents a function.Yayy!! We found our answer. It's ' Option D '.

A supermarket had bags of red grapes for $13.00 for 5 bags. They also had bags of green grapes priced at $5.08 for 2 bags. Which type of grape is most expensive?
Answer:
Red grapes.
Step-by-step explanation:
If you find how much one bag of each grape cost which is:
$13.00 ÷ 5 = 2.60 (1 bag of red grapes)
$5.08 ÷ 2 = $2.54 (1 bag of green grapes)
See the price and you'll know it is red grapes.

What is an equation of the line that passes through the points (5,2) and (-5,6)?
Put your answer in fully reduced form.
Answer: y = -2/5x + 4
Steps:
First find the slope of the equation y=mx+b.
slope equation (m=y2-y1/x2-x1)
Then plug in your coordinates, which the first set is (5,2) and the second set if (-5,6). m = 6 - 2/ -5 - 5
Which your answer will be 4/-10, simplify it by dividing both by 2 to get -2/5 for your slope.
Next, find your y-intercept (b).
substitute the first set of coordinates into the equation y=mx+b
Substitute: 2 = -2/5 (5) +b
Then multiply -2/5 with 5 to get (-2). Your equation should now reduce to be
2 = -2 +b
Do inverse operations on both sides by adding 2 to each side (the 2 side and the -2+b side).
This gets rid of the -2 and since we added 2 to both sides, your final equation should look like 4 = b for your y-intercept.
Plug in everything to get y = -2/5x + 4
4. The ratio of the measures of the three angles in a triangle is 7:8:5, what is the
measure of the smallest angle?
Your answer
Step-by-step explanation:
let the angles be ' 7x, 8x and 5x'
as we know, the sum of all the angles of a triangle is 180 degree, so,
7x + 8x + 5x = 180
20 = 180
x = 180/2
x = 90 degrees
7x = 7 × 90 = 630 degree
8x = 8 × 90 = 720 degrees
5x = 5 × 90 = 540 degrees
therefore, 5x is the smallest degrees

Which equation represents the line that has a slope of 4 and passes through the point (2, 7)?
Answer:
The answer is y = 4x - 1.
Step-by-step explanation:
☆The equation we'll be using: y = mx + b
☆Since we already have the slope. we have to find the y-intercept.
☆[tex]y = mx + b \\ \\ 7 = 4(2) + b \\ 7 = 8 + b \\ \frac{ - 8 = - 8 \: \: \: \: \: \: \: \: \: \: \: }{ - 1 = b \: \: \: \: \: \: \: \: \: \: } [/tex]

Roger has two golden retrievers, Sadie and Buddy. buddy weighs 14 pounds more than Sadie. If their total weight is 136 pounds, how much does Sadie weigh
Answer:
Sadie weighs 61 pounds.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
Sadie's weight is x.
Buddy's weight is y.
Buddy weighs 14 pounds more than Sadie.
This means that [tex]y = x + 14[/tex]
Their total weight is 136 pounds.
This means that
[tex]x + y = 136[/tex]
Since [tex]y = x + 14[/tex]
[tex]x + x + 14 = 136[/tex]
[tex]2x = 122[/tex]
[tex]x = \frac{122}{2}[/tex]
[tex]x = 61[/tex]
Sadie weighs 61 pounds.

Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle. He spent 2 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
a.(2 × 25) + 105
b.(105 x 2) + (25 x 2)
c.2 x (25 + 105)
d.2 x 25 × 105
Answer:
a.(2 × 25) + 105
Step-by-step explanation:
Let the number of hours spent repairing the bike = x
Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle.
Therefore, our algebraic expression
= $25× x + $105
= 25x + 105
We were told in the question that He spent 2 hours repairing her bike.
Hence:
25 × 2 + 105
Therefore, the correct option is option a
a.(2 × 25) + 105

Can the Pythagorean Theorem be used to find a distance in the coordinate plane?
Answer:
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.
Step-by-step explanation:
hope it help
Answer:
Yes it can be used because there is a right angle and by using 3 points u form a right triangle and then u will can find distance
Hey need this ASAP I’ve work through almost just need this one
Answer:
He must score an 86 or more on his third test.
Step-by-step explanation:
An average is calculated by the sum of the numbers divided by the total number (#) of numbers (if that makes sense). Knowing this, we can write an algebraic equation in order to find the answer. Let x equal the unknown number.
John's previous test scores and this test score now must be at least an average of 90 or more. Therefore, the equation would be [tex]\frac{86+98+x}{3} \geq 90[/tex]. Isolate x to find the answer:
[tex]\frac{86+98+x}{3}\geq 90\\ \frac{184+x}{3} \geq 90\\184 + x \geq 270\\x \geq 86[/tex]
Therefore, he needs to get at least a 86 or higher.

Answer:
Streamers cost 2.50 and balloons cost 1.25.
Step-by-step explanation:
Pls mark brainliest.
Answer:
Balloon : $1.25
Streamer : $ 2.50
Step-by-step explanation:
Form simultaneous equations.
Let streamer be represented by ------------s
Let balloons be represented by ------------b
So the equations will be;
3s + 2b = 10 ----------------i
2s + 1b = 6.25---------------ii
Make the terms with s equal by multiplication
[3s + 2b = 10 ]2
[2s + 1b = 6.25]3
Perform subtraction
6s + 4b = 20
6s + 3b = 18.75
b = 1.25 ---------iii
Use iii in ii as;
2s + 1b = 6.25
2s + 1.25 = 6.25
2s = 6.25 - 1.25
2s = 5.00
s= 5.00 / 2
s= 2.5
Hence ; a balloon is $1.25 and a streamer is $2.5
