if a jigsaw puzzle is priced 17.00 but cost 17.68 at the register what is sales tax rate
Answer:4%
Step-by-step explanation:
From the question, we are informed that a jigsaw puzzle is priced 17.00 but cost 17.68 at the register. This means that the sales tax is (17.68 - 17.00) = 0.68.
Therefore, the sales tax rate will be calculated as:
= (0.68 / 17.00) × 100
= 4%
The sales tax rate is 4%
Please help due in less than 3 hours!!!!!!!! When Anne biked down the canyon, she averaged 30 miles per hour. At this rate, how long did it take her to bike 1 mile?
Answer:
2 min.
Step-by-step explanation:
1h is 60 min so divide 60 by 30 and you get 2
Answer:
It took Anne 1/30 of an hour to bike 1 mile.
Step-by-step explanation:
Unit Rate - 30 miles/ 1 hour
[tex]\frac{30 miles}{1 hour} = \frac{1 mile}{? hour}[/tex]
Based on the visual above, we need to find the proportion.
30 miles divided 30 equals to 1 mile.
What is 1 hour divided by 30? Remember: whatever is done to the numerator must be done to the denominator!
1 divided by 30 equals 1/30. Since the unit is hour, the answer is 1/30 of an hour.
How can we rewrite 6 – (-5)
Answer:
6+5
Step-by-step explanation:
Answer:
6+5
Step-by-step explanation:
If you ever have two negative signs together, like here, you get a positive sign. Here we have 6-(-5), the minus sign and the -5 are next to each other, creating a positive sign or turning the -5 into positive 5. This chart might help:

What is the equation of the line that has a slope of 3 and goes through the point (3, 4).
Use the point-slope formula and then solve for y.
y - y_1 = m(x - x_1)
y_1 = 4
x_1 = 3
m = 3
y - 4 = 3(x - 3)
y - 4 = 3x - 9
y = 3x - 9 + 4
y = 3x - 5

Sometimes on a Saturday, they ride their bikes toward each other's houses and meet somewhere in between. Taylor is a very consistent rider - she finds that her speed is always very close to 12.5 miles per hour. Anya rides more slowly than Taylor, but she is working out and so she is becoming a faster rider as the weeks go by. On a Saturday in July, the two friends set out on their bikes at 8 am. Taylor rides at 12.5 miles per hour, and Anya rides at 5.5 miles per hour. After one hour, how far apart are they?

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
Answer:
350 girls
Step-by-step explanation:
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.

I can't figure out d - 11
Answer: d = 17
Step-by-step explanation:
d - 11 = 6
So, by adding 11 to each side you'd get rid of the -11 on the left and isolate the variable
d = 17
The width of a rectangle is three more than twice the length. The perimeter is 96 inches. Find the length and the width.
Answer:
The length of the rectangle is 15 inches and the width is 33 inches
Step-by-step explanation:
The dimensions for the rectangle are as follows:
L=L and W=2L+3
The equation for perimeter of a rectangle is:
P=2l+2w
To Solve:
1. Plug values into perimeter equation
96=2(L)+2(2L+3)
2. Simplify the equation above.
96=2L+4L+6
3. Combine like terms:
96=6L+6
4. Solve for L by subtracting 6 from both sides:
90=6L
5. Solve for L by dividing both sides by 6:
15=L.
6. Plug 15 into the equation for the width:
2(15)+3=w
30+3=w.

1) Factorise fully 8y^3 - 6y
[tex]8y^3-6y\\2y(4y^2-3)[/tex]
Factor 2 out because both 8 and 6 can be divided by 2.
Factor y out because there are same y's in a polynomial.
Answer:
2y (4y^2-3)
Step-by-step explanation:
8y^3 - 6y
Over here, we need to first look for the value they have in common
and u can identify that its "y". Now look for a no. that u can multiply both the no.s inside with. In this case, it two...but usually u need to pick the biggest value u can multiply both the no.s with.
So, now we need to put the common value outside the bracket-
2y (......)
2y * 4y^2 can give u 8y^3, therefore this will be the first value inside the bracket, the next value will be 2y*-3 coz it will give u -6y [Be careful of the signs].
So the ans would end up being-
2y (4y^2-3)
