Two-thirds of the T-shirts in a T-shirt shop are blue. Three-sevenths of those T-shirts are on sale.
One-half of the blue T-shirts that are on sale are size medium. What fraction of the shop's T-shirts are
blue T-shirts that are on sale and are size medium? Explain.
Answers
Answer:
1/7
Step-by-step explanation:
Of all the shirts, 2/3 of the t-shirts are blue.
Of the blue shirts, 3/7 are on sale. Of all the shirts, 2/7 are on sale and blue.
[tex]\frac{2}{3}*\frac{3}{7} =\frac{2}{7}[/tex]
Of the blue shirts on sale, 1/2 are size medium. Of all the shirts, 1/7 are on sale, blue, and size medium.
[tex]\frac{2}{7} *\frac{1}{2} =\frac{1}{7}[/tex]

pls help with this one -4 divided by - 2/3
Answers
Answer:
6
Step-by-step explanation:
what you do is because you are dividing -4 by -2/3 you have to flip -2/3 to make it -3/2..
so ...
-4/ -2/3 = -4 x -3/2 ( so here you take -2/3 and flip it and multiply by -4)
now all you do is multiply
12/2 you get 6 ! HOPE this helped out alittle
the 15% tip on craig's lunch bill came to $2.40 what was the amount of bill before the tip? show workouts
Answers
Remember to write the percent as a decimal for the calculations
Think of the tip as the question 2.40 is 15% of what number?
2.40/x = 15/100
Multiply both sides by x
2.40 = 15x/100
2.40 = 0.15x
So the tip 2.40 = 0.15x
Divide both sides 0.15 to solve for x
And that makes the cost before the tip 2.40/0.15 = 16.00
$16.00
The total bill for his lunch would be the cost before the tip plus the tip
We can calculate the final bill as $16.00 + $2.40 = $18.40

What is the distance between the
two points
(7.8)
{3,2)
Answers
To find the exact difference, we have to subtract the two decimal points.
1. First, we'll subtract the whole number. Then, we'll subtract the decimal number. This will make mental math easier.
a. 7 - 3 = 4
b. 8 - 2 = 6
2. Add the answers together to get your final answer.
a. = 4.6
The exact distance between the two points is 4.6. If you can't figure this strategy out, do algorithm. The simplist way to solve this is to use a calculator, which I checked my answer on. Have a nice day! :)
A car uses 8.4 liters of petrol for a 112 mile journey. When the tank is full, the car holds 54 liters of petrol. How far should the car be able to travel on a full tank of petrol.
Answers
Answer:
720 miles
Step-by-step explanation:
A car uses 8.4 liters of petrol for a 112 mile journey.
In 1 litres = [tex]\dfrac{112}{8.4}\ \text{miles}[/tex] of journey
We need to find far should the car be able to travel on a full tank of petrol i.e. 54 litres of petrol.
[tex]54\ l=\dfrac{112}{8.4}\times 54\\\\=720\ \text{miles}[/tex]
So, the car can travel 720 miles when it holds 54 lirres of petrol.
At a football stadium, 4% of the fans in attendance were teenagers. If there were 120 teenagers at the football stadium, what was the total number of people at the stadium?
Answers
Answer:
3000 people
Step-by-step explanation:
4% teenagers --> 120 teenagers were there
120/4 means 1% so 30 is 1%
1% times 100 is 100% so 30 times 100 equals 100% so 3000 is 100% of the people at the stadium
120/1= 120*25= 3000
.04*3000= 120
3000 people in total

Find the distance between each pair of parallel lines with the given equations y=3x, y=3x+10
Answers
Answer:
sqrt10
Step-by-step explanation:
Since the closest distance between two parallel lines is a line that is perpindicular to them, we first find the line of the slope that is perpindicular to both lines. Since slope of line y = 3x+10 is 3, the slope of the line that is perpinduclar is -1/3. Therefore y = -1/3x is perpindicluar to both lines. We then find the intersection point of each line. We find said points by setting the lines equal to each other. 3x+10=-1/3x, x = -3 therefore y = 1. For the second line we get we find the origin is the intersection. Therefore since this forms a right triangle with the x axis, we find that the distance is 3^2+1^2 = sqrt10

Write the standard form of the equation of a line with a slope of 2 passing through the point (-4, -3).
Select one:
a. 2x - y + 5 = 0
b. -x + 2y + 2 = 0
c. x - 2y - 2 = 0
d. -2x + y - 5 = 0
Answers
Step 1: We need to determine b by using slope-intercept form, the given slope, and the given line.
[tex]-3 = 2(-4) + b\\\\-3 = -8 + b\\\\5 = b[/tex]
Step 2: Now we create the slope-intercept form for the line.
[tex]y = 2x + 5[/tex]
Step 3: We can now change the above equation to standard form.
[tex]y = 2x + 5\\\\-2x + y = 5\\\\-2x + y - 5 = 0[/tex]
The equation of the line in STANDARD FORM is: D. -2x + y - 5 = 0.

mi,
Sally plans to stop half way and pick up something to eat at the deli. What coordinate is the deli?
Answers
Answer:
Sally is 10 miles
The coordinate ofthe deli is (1, -1)
Step-by-step explanation:
✍️Coordinate of Sally = (-3, 2)
Coordinate of Ocean Front = (5, -4)
The distance of Sally to Ocean Front Housing Complex = the distance between point (-3, 2) and (5, -4).
Use the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to calculate the distance between (-3, 2) and (5, -4):
[tex] d = \sqrt{(5 -(-3))^2 + (-4 - 2)^2} [/tex]
[tex] d = \sqrt{(8)^2 + (-6)^2} [/tex]
[tex] d = \sqrt{64 + 36} [/tex]
[tex] d = \sqrt{100} = 10 [/tex]
✅The distance of Sally is 10 miles
✍️the coordinate of Deli would be half the distance between Sally and Ocean Front.
Therefore, use the midpoint formula to calculate the coordinate of the midpoint between Sally (-3, 2) and Ocean Front (5, -4).
Midpoint of (-3, 2) and (5, -4).
[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Plug in the values
[tex] M(\frac{-3 + 5}{2}, \frac{2 +(-4)}{2}) [/tex]
[tex] M(\frac{2}{2}, \frac{-2}{2}) [/tex]
[tex] M(1, -1) [/tex]
✅The coordinate ofthe deli is (1, -1)
