Answer:
3-> 10
60<-200
Step-by-step explanation:
X times something = Y
6 times something= 20
something= 20/6= 10/3
3 times 10/3 = 10
200 / 10/3 = 200 times 3/10 =60
y=10
x=60

Which best describes the error in finding the simple interest earned on $500 at 6% for 18 months? They did not convert $500 to cents. They did not multiply in the correct order. They did not place the decimal in the answer correctly. They did not convert 18 months to years. Question 2 Correct the error. The simple interest earned equals $ .
Answer:
45
OThey did not covert the 18 months to year
Step-by-step explanation:
I= PxRxT. 18/12=1.5
I=500x0.06x1.5
I=45
A car is driving down a road at a normal speed of 50 miles per hour. It enters a hilly area of gradual incline and decline, where it must drive 50 miles up hill and then 50 miles downhill. If this 100 mile section of road takes 2.6 hours to traverse instead of the expected 2 hours (the time it would take if the road was completely flat) determine the speed that the hills add or subtract when going over.
Answer:
Step-by-step explanation:
I'm going to assume that the car goes 50-x mph uphill and 50+x mph downhill.
x ≅ 24 miles per hour
26 mph uphill and 74 mph downhill

Deposited 3,000$ and it earned 300$ in simple interest after 5 years what’s the interest rate
Answer:
The interest rate is 2%
Step-by-step explanation:
Simple Interest
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
The principal is P=$3,000 and it earned I=$300 in t=5 years. Thus the interest rate can be calculated by solving for r:
[tex]\displaystyle r=\frac{I}{P.t}[/tex]
[tex]\displaystyle r=\frac{300}{3,000*5}[/tex]
[tex]\displaystyle r=\frac{300}{15,000}[/tex]
r = 0.02
The interest rate is 2%

plot 2 2/3 and 1 7/9.
Answer:
Down below :)
Step-by-step explanation:
Hey there!
To plot a fraction on a graph you have to turn it into an improper fraction. In this case, the improper fraction for 2 2/3 is 8/3 and the improper fraction for 1 7/9 is 16/9.
*Note: To find the improper fraction of a fraction you must multiply the denominator by the whole number and then add the numerator.
With these two improper fractions...
8/3
16/9 (Simplify it down to 8/3 since both 16 and 9 go into 3)
You can now graph it. To graph, the numerator tells you how many times to go up and the denominator tells you how many times to go right. IF IT'S NEGATIVE IT WILL DO THE OPPOSITE IF THE NUMERATOR IS NEGATIVE IT WILL GO DOWN INSTEAD OF UP AND IF THE DENOMINATOR IS NEGATIVE IT WILL GO LEFT INSTEAD OF RIGHT.
8/9 means you need to start at the origin, (0,0) and go 8 up and 3 to the right. 8/3 means you start at the origin and go 8 up and 3 to the right. You will almost always start at the origin.
I really hope this helps :)

On Saturday, the temperature at midnight
was -17 °F
At noon, the temperature was greater than
10°F.
About how many degrees did the
temperature change from midnight to
noon? Explain your reasoning.
Answer:
About 30°F.
Step-by-step explanation:
-17 is close to -20 so -20+20=0 then it says greater then 10 so then 0+10.

Is the point (3, 4) a solution to the linear equation 5x - 9y = 32?
Answer:
it equals -21 so no
Step-by-step explanation:
happy valentines!
Answer:
No, It does not.
Step-by-step explanation:
(3,4) means (x,y). When you insert 3 to x and 4 to y, You get this:
5(3)-9(4)=32
If you multiply 5 and 3, You get 15.
15-9(4)=32
If you multiply 9 and 4, you get 36.
15-36=32
If you subtract 15-36, you get -21.
This is why the answer is no because -21 does not equal 32
-21 ≠ 32
Hope this helps! :)

James bought 4 tubes of paint to use for an art project. He paid the same amount for each tube, and he spent less than $20 in all. Solve for the cost of tube of paint.
(You have to write it with inequalities, not an equal sign.)
Joseph must sell more than 20 ice cream cones in order to make a profit. He has already sold 6 cones. How many cones must Joseph still sell?
(You have to write it in inequalities, not an equal sign. For example, NOT 2=25, but like THIS: 2<25)
Answer: Problem 1: x<$5
Problem 2: 6 + c ≥ 20
Step-by-step explanation:
number of tubes=4
total=<$20
4(x)<$20
x<$20/4
x<$5
number of ice cream cones needed to make profit=20
number of ice cream cones sold so far= 6
how many left?= c
6 + c ≥ 20

{2, 3, 8, 19, 46, ...}
Answer:
111
Step-by-step explanation:
Multiply the number by two and then add the number right before it.
3*2+2=8
8*2+3=19
19*2+8=46
46*2+19=111
and so on.
Given the following table and graph write the equation to represent the exponential function.
Answer:
The exponential equation is y = -2×(1/2)^x
Step-by-step explanation:
Ok we have a couple things to note here:
1) The horizontal asymptote of the function is the x axis (always nice)
2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)
3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:
y=a×b^x----> -1 = (-2)(b) ------> b=1/2
Therefore, the exponential equation is y = -2×(1/2)^x
Test:
At x = 0, y= -2
At x = -1, y = (-2)*(1/2)^-1 = (-2)*2 = -4
At x=2, y = (-2)*(1/2)^2= (-2)*(1/4) = -1/2
Thus we can be quite certain that this is correct

Answer:
141.12 cm^2
Step-by-step explanation:
The formula for area of a triangle is [tex]h(b1+b2)1/2[/tex]. you have that:
b1, or base 1, = 12.2
b2, or base 2, = 10.2
h, or height, = 12.6
so plug this into the formula:
[tex]12.6(12.2+10.2)1/2\\12.6(22.4)1/2\\12.6*11.2\\141.12[/tex]
Answer:
141.12cm^2
Step-by-step explanation:
First split the trapezoid into two shapes: a rectangle and a triangle.
The area of the rectangle is (10.2cm)(12.6cm) = 128.52cm^2
Finding the area of the triangle is a little trickier. In order to find the base of the triangle, subtract 12.2-10.2=2. The area of a triangle is defined as A=1/2bh, so let's plug in our values:
A = (1/2)(2)(12.6) = 12.6cm^2
Now, add them together.
12.6cm^2 + 128.52cm^2 = 141.12cm^2

PLS HELP ME :(( what is the initial value of all linear functions that show a proportional relationship?
Answer:
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y-value of the point where the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope.
