The sum is
.
Subtract.
2.53 – 0.8 = ?
The difference is
.
Answer:
The answer to the first question is 7.15
The answer to the second question is 1.73
Answer:
7.15; 1.73
Step-by-step explanation:
6.2 is the same as 6.20, so:
6.20
+ 0.95
= 7.15
0.8 is the same as 0.80, so:
2.53
- 0.80
= 1.73

5.) A graph showing a proportional relationship will...
Answer:
C. A straight line that goes through the origin.
Step-by-step explanation:
A graph representing a proportional relationship between variable x and variable y will have a straight line. This straight line must also cut across or pass through the point of origin (0, 0).
Therefore, the answer is: "A straight line that goes through the origin."

Grayson is playing a game in which the object is to obtain a 0 by adding the points scored during each round.
Round 1 Round 2 Round 3 Round 4 Round 5
4
7
1
-12
Based on the points he scored during the first 4 rounds, what score does Grayson need on the 5th round?
-24
-11
12
Answer:
0. See explanation below.
Step-by-step explanation:
Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.
For rounds 1 to 4,
4 + 7 + 1 + -12 = 12 - 12 = 0
The summation of points in the first four rounds already results to a zero.
Let us see if the addition of any of the three options for round 5 will still result in a zero!
0 + -24 = -24
0 + -11 = -11
0 + 12 = 12
So all the options here are wrong. The only option that would have been correct is 0.
Since 4 + 7 + 1 + -12 + 0 = 0
Maybe the complete question has 0 as the fourth option. Use that.

A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day. How many days will it take them to raise enough money for the whole donation?
Answer:
Number of days= 12.5
Step-by-step explanation:
Giving the following information:
A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day.
To calculate the number of days required to raise $175, we need to use the following formula:
Number of days= total amount / profit per day
Number of days= 175/14
Number of days= 12.5

A family went on vacation and used 45.3 gallons of gasoline to travel 150 miles. How many total gallons of gasoline will they need to travel 200 more miles?
a.) 15.1 gallons
c.) 60.4 gallons
b.) 90.6 gallons
d.) 105.7gallons
Answer:
d) [tex]105.7\ \text{gallons}[/tex]
Step-by-step explanation:
[tex]150\ \text{miles}[/tex] requires [tex]45.3\ \text{gallons of fuel}[/tex]
[tex]1\ \text{mile}[/tex] requires [tex]\dfrac{45.3}{150}\ \text{gallons of fuel}[/tex]
[tex]200\ \text{miles}[/tex] requires [tex]200\times \dfrac{45.3}{150}=60.4\ \text{gallons of fuel}[/tex]
So, total amount of gasoline required for the trip is [tex]60.4+45.3=105.7\ \text{gallons}[/tex].
A photographer is 6 feet tall and cast a shadow that is 2 feet long. He is photographing a palm tree with a shadow that is 7 feet long. What is the height of the tree
Answer: The height of the tree is 21 feet.
Step-by-step explanation:
Here we can assume that the angle at which the sun impacts the photographer and the tree to be the same angle.
Then we can think in both cases as triangles rectangles, where the height is a cathetus, and the shadow is the other cathetus.
Then we will have a relationship like:
Tg(angle) = shadow/height
height = shadow/Tg(angle)
Now, because for both triangles we have the same angle, then Tg(angle) will be the same number for both cases, and we can just think of it as constant K
Tg(angle) = K
Then we have the equation:
Height = Shadow/K
We know that the photographer is 6ft tall, and his shadow is 2 ft long, we can replace those two things in the above equation and find the value of k:
6ft = 2ft/K
K = 2ft/6ft = (1/3)
Now we know that the shadow of the tree is 7ft long, then the height will be:
height = 7ft/(1/3) = 7ft*3 = 21ft
The tree is 21 ft tall.

A carpenter is making a ramp for a ski jump.
The ramp is made from a 25 ft. board titled at
a 30° angle from the ground. Approximately
how far off the ground is the end of the ramp?
Answer:
12.5 ft
Step-by-step explanation:
To solve this, we would be applying Pythagoras theorem to it.
Assuming that our given angle is the hypotenuse. Since it says it's closer to the elevated angle. Then, we're looking for a side, A, which is on the opposite side of the angle in the question.
Using sine rule, we know that
Sin 30 = x/25
x = 25 sin 30
x = 25 * 0.5
x = 12.5 ft
Therefore the answer is 12.5 ft
wendy jogs every three days and xue jogs every four days. if today is a wednesday and wendy and sue both jog today, in how many days will they both jog again on the same day of the week which day of the week will it be
Answer:
Monday
Step-by-step explanation:
Given
[tex]Wendy = 3[/tex]
[tex]Xue = 4[/tex]
[tex]Today = Wednesday[/tex]
Required
Determine when next they will jog together
First, we calculate the L.C.M of the days they jog:
[tex]3 = 1 * 3[/tex] --- Wendy
[tex]4 = 1 * 2 * 2[/tex] ---- Xue
[tex]LCM = 1 * 3 * 2 * 2[/tex]
[tex]LCM = 12[/tex]
This means that they meet on the 12th day; The 12th day after a Wednesday is Monday.
Hence, they will meet on a Monday
Over what interval does this function remain constant? Do not use any spaces in your interval.
Answer:
We conclude that the function remains constant over the interval [0, 2].
Step-by-step explanation:
We know that if x increases from left to right and y remains constant, the function remains constant over a certain interval.
From the given graph below, it is clear that from x = 0 to x = 2 the value of y does not change.
In other words, the value of y remains constant from x = 0 to x = 2.
i.e.
at x = 0, y = 5
at x = 1, y = 5
at x = 2, y = 5
Therefore, we conclude that the function remains constant over the interval [0, 2].

sine of negative eleven pi divided by twelve.
A. square root of six plus square root of two divided by four.
B. negative square root of six minus square root of two divided by four.
C. square root of two minus square root of six divided by four.
D. square root of six minus square root of two divided by four.
Answer:
(√2 - √6) / 4
C. square root of two minus square root of six divided by four.
Step-by-step explanation:
sine of negative eleven pi divided by twelve.
We have :
sin(-11π/12)
sin((4 - 15)π / 12) = sin(4π/12 - 15π/12)
sin(4π/12 - 15π/12) = sin(π/3 - 5π/4)
Recall:
Angle difference formula:
sin(A - B) = sinAcosB - sinBcosA
Hence,
sin(π/3 - 5π/4) = sin(π/3) cos(5π/4) − sin(5π/4) cos(π/3)
From trigonometry:
sinπ/3 = √3/2
cos5π/4 = -√2/2
sin5π/4 = -√2/2
cos π/3 = 1/2
(√3/2) (-√2/2) − (-√2/2) (1/2)
-√6/4 - -√2/4
-√6/4 + √2/4
√2/4 - √6/4
(√2 - √6) / 4

12 baseball cards cost $25 = How many dollars per baseball card?
Answer:
2.08333333333
Step-by-step explanation:
Answer: Each card costs $2.08
Step-by-step explanation: This is because you need to divide the cost for 12 cards by 12. 25/12 is 2.08333333... so you can round that to $2.08.
Given the system of constraints name all vertices. Then find the maximum value of the given objective
x≥0
y≥0
y≤ 1/3x+1
5≥y+x
Objective function C = 7x-2y
Answer:
[tex]35[/tex]
Step-by-step explanation:
The constraints are
The red line represents the function
[tex]y\leq \dfrac{1}{3}x+1[/tex]
At [tex]y=0[/tex]
[tex]0=\dfrac{1}{3}x+1\\\Rightarrow -1=\dfrac{1}{3}x\\\Rightarrow x=-3[/tex]
At [tex]x=0[/tex]
[tex]y=0+1\\\Rightarrow y=1[/tex]
Two points are [tex](-3,0),(0,1)[/tex]
The blue line represents the function
[tex]5\geq y+x[/tex]
at [tex]y=0[/tex]
[tex]5=x[/tex]
at [tex]x=0[/tex]
[tex]y=5[/tex]
Two points are [tex](5,0),(0,5)[/tex]
The other two constraints are [tex]x\geq 0[/tex], [tex]y\geq 0[/tex]. So, the point has to be in the first quadrant
From the graph it can be seen there are two points where the function will be maximum let us check them.
[tex](3,2)[/tex]
[tex]7x-2y=7\times 3-2\times 2=17[/tex]
[tex](5,0)[/tex]
[tex]7x-2y=7\times 5-2\times 0=35[/tex]
So, the maximum value of the function is [tex]35[/tex].
Whoever answers number 1 and 2 gets brainliest!! :)
Answer:
1: Yes they are both equivalent because 48/8 is 6 and 24/4 is 6.
2: They would score 750 points because you divide 150 by 3 and get 50, then you multiply 50 by 15 and get 750!

Write the mixed number as an improper fraction.
23/4 =
Answer:
Improper fraction: 23/4
Mixed number: 5 3/4
Answer:
5 3/4
Step-by-step explanation:
how many times does 4 go into 23? well 4×5=20, which seems like too little, so we'll try 4×6=24,
but that's too much so were sticking with the 5. So 5 is the first number
then since 4 times 5 is 20. but you have 23, there are 3 extra numbers
So you make them into a fraction: 3/4
So the answer is 5 3/4
also 23/4 is the improper fraction, 5 3/4 is the mixed number
