HEYYY!! Who can help me?? .. (I’m kinda slow lol)
Answer:
The answer should be A
Step-by-step explanation:
y=3x+2
First, check the y-intercept, which is 2 in this case. Only A, B, and D crosses the y-axis at 2.
Next, check the slope (I didn't calculate every one of the slopes)
the slope, from the equation is 3, so the graph should be positive (left to right always)
Only graph A has a positive slope and a y-intercept of 2.

c = grocery store charges
Tax is 8% added to the charges.
Which expression shows the total charges with tax?
A. 1.8c
B. 1.08c
The total charge with tax will be 1.08c.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Grocery store charges = c
And, Tax is 8% added to the charges.
Now,
Since, Tax is 8% added to the charges.
Hence, The total charge with tax = c + 8% of c
= c + 8/100 × c
= c + 0.08c
= 1.08c
Thus, The total charge with tax = 1.08c.

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations)
Answer:
52[tex]\pi[/tex]
Step-by-step explanation:
The total shaded are will be the area of big circle - not shaded circle + little shaded circle.
The are of big shaded circle: [tex]\pi[/tex][tex]r^{2}[/tex] So, A=[tex]\pi[/tex](8^2)= 64[tex]\pi[/tex]
The are of not shaded circle: [tex]\pi r^{2}[/tex] So, A= [tex]\pi[/tex](4^2)= 16[tex]\pi[/tex]

A counter in Brendan's kitchen is 1 yard wide and 3 yards long. Brendan wants to replace the counter with a granite countertop, which would cost $206.00 per square yard. How much would the granite countertop cost?
Answer:
The new granite countertop will cost $824.
Step-by-step explanation:
Step 1: The problem is to determine how many yards per square that the countertop is made up of.
This is the equivalent of finding the square area of the countertop.
The formula for the square area of a rectangle is given as L x W.
Where L = Lenght which is equal to 3 yards
W = 1 yard
Step 2:
Cost of per square yard required therefore is
3 x 1 = 3 square Yards.
The granite required for the countertop project therefore will cost:
$206 x 3 = $824.00

Damon treated his sister to lunch while visiting her in Weston. Thier lunch cost $40, and the sales tax in Weston is 15%. If Damon left a 20% tip on the $40, how much in total did he pay?
Given:
Cost of lunch = $40
Rate of sales tax = 15%
Rate of tip = 20% on $40.
To find:
The amount Damon pay.
Solution:
We have,
Cost of lunch = $40
Rate of sales tax = 15%
[tex]\text{Sales tax}=\dfrac{15}{100}\times 40[/tex]
[tex]\text{Sales tax}=6[/tex]
Rate of tip = 20% on $40
[tex]\text{Tip}=\dfrac{20}{100}\times 40[/tex]
[tex]\text{Tip}=8[/tex]
Now,
Total amount = Amount + Sales tax + Tip
= [tex]40+6+8[/tex]
= [tex]54[/tex]
Therefore, Damon pays total $54.

what number is one hundred more than 890
Answer:
990
Do 100+890
its simple math
The number that is one hundred more than 890 would be,
⇒ 990
The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that,
To find a number that is one hundred more than 890.
Let us assume that,
The number that is one hundred more than 890 = x
Hence, it can be written as,
⇒ x = 890 + 100
Solve for x,
⇒ x = 990
Therefore, the number that is one hundred more than 890 = 990

City J is between City K and City L. You know the round-trip distance from City K to City L is
548 miles and the round-trip distance from City K to City J is 326 miles. Find the distance
between City J and City L. Justify your answer.
Answer:
JL is 111 miles
Step-by-step explanation:
When we talk of round trips, we mean the distance going plus the distance coming
To get the actual distance between the two places, we need to divide by 2
K to L is round trip 548 miles
K to L distance is 548/2 = 274 miles
K to J round trip is 326 miles
K to J distance is 326/2 = 163 miles
From what we have ;
KL = KJ + JL
274 = 163 + JL
JL = 274-163
JL = 111 miles
To justify our answer, we can see that J is between K and L
if we added the distance KJ and JL, we should get the distance KL
from the calculations we have made, we can see that this is correct and our answer is justified
A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.
Complete question :
A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming
Which statement best describes the depth of the fish
From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.
From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
Answer:
From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
Step-by-step explanation:
Given the equation :
y = - 7x - 3
y = depth of fish in meters ; x = Number of seconds fish has been swimming
From the equation ; which is written according to the slope - intercept equation, ; y = mx + c
The slope, m = - 7 is the rate of change in y per unit of x
c = intercept, constant, value of y when x = 0
Hence, the true statement in the equation is :
-7 represents descent and meams fish descents at a rate of 7 m per second
At x = 0, the fish is at a depth of 3 m
