A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £4.80 and the normal price of a jumper is £14.60.
How much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate?
Answer:
The cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.
Step-by-step explanation:
Since a clothes shop has some special offers, for which T-shirts are buy one get one free and jumpers are 3 for 2, and the normal price of a T-shirt is £ 4.80 and the normal price of a jumper is £ 14.60, to determine how much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate, the following calculation must be performed:
4 T shirts = 2 + 2
4.80 x 2 = 9.60
5 jumpers = 2 (+1) + 2
4 x 14.60 = 58.40
Therefore, the cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.

Here's the solution,
the opposite angles of parallelogram are equal, so, Angle G = Angle E
=》3x + 11 = 5x - 9
=》5x - 3x = 11 + 9
=》2x = 20
=》x = 10
value of x = 10
now, Angle G = 5x - 9
=》(5 × 10) - 9
=》50 - 9
=》41°
Angle G and Angle F are supplementary, so
=》 41° + Angle F = 180°
=》Angle F = 180° - 41°
=》Angle F = 139°
What are the first five terms of the sequence given by the formula an = 4n + 1?
Answer:
5,9,13,17,21
Step-by-step explanation:
We can the values in "n"
a(1)=4(1)+1
a(1)=5
a(2)=4(2)+1
a(2)=9
a(3)=4(3)+1
a(3)=13
a(4)=4(4)+1
a(4)=17
a(5)=4(5)+1
a(5)=21
As you can see, each value consecutively increases by 4, this is also known as the common difference (d).

2 workers are working together. They finish their work in 12 hours. if the ratio of their work together is 3:2 how long did each of them work
Answer:
7.2 and 4.8hrs
Step-by-step explanation:
Given the ratio it took them to finish work as 3:2
Total ratio = 3+2 = 5
For the larger ratio;
3/5 *12
= 36/5
= 7.2hrs
For the shorter ratio;
2/5 * 12
= 24/5
= 4.8hrs
Hence the first worker worked for 7.2hrs while the second was 4.8hrs

Suppose it takes you 14 hour to drive to the movie theater at a rate of 40 mph. Your friend lives closer to the movie theater than you do. Which inequality represents the distance d (in miles) that your friend lives from the movie theater?
A. d < 10
B. d > 10
C. d > 40
D. d < 160
Answer: (d)
Step-by-step explanation:
Given
It takes 14 hours with 40 mph to reach the theatre
so, the distance traveled is given by
[tex]\Rightarrow d_1=40\times 14\\\Rightarrow d_1=560\ \text{miles}[/tex]
It is given that d is the distance from theatre to friend's house
So, d must be less than [tex]d_1[/tex] i.e.
[tex]d<d_1[/tex]
So, the most appropriate option out of the given is option (d) as d must be less than 560 and it is possible that it maybe less than 160.
Answer:
I believe you meant 1/4 instead of 14... it would be d. If you meant 14 then it would be 560 but there would be no answer choice.

The probability of drawing a blue
marble from a bag containing
these marbles is į
If you replace the marble each time,
predict how many times a blue marble
will be chosen out of 50 draws.
[?] times
Enter
Answer:
25 times
Step-by-step explanation:
From the question:
Number of :
Yellow = 2
Red = 3
Blue = 5
P(blue) = required outcome / Total possible outcomes = 5/ 10 = 1/2
If marble is drawn with replacement :
Number of times a blue marble is drawn from 50 trials :
P(blue marble) * 50
1/2 * 50
= 25 times
The distance between City A and City B is 250 miles. On a certain wall map, this is
represented by a length of 1.5 feet. On the map, how many feet would there be between City C
and City D, two cities that are actually 450 miles apart?
Answer:
Step-by-step explanation:
1.5 feet x
====== = ======
250 miles 450
Multiply both sides by 450
1.5 * 450 x
====== =
250 miles
x = 2.7 feet
1 foot = 12 inches
0.7 foot = x
x = 12 * 0.7
x = 8.4 inches
Answer
Either 2.7 feet
or 2 feet 8 inches.

30-60-90 triangle theorem
Find the slope of the line that passes through the points
(-5,-6) and (5,10)
Answer:
8/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (10- -6)/(5 - -5)
= (10+6)(5+5)
= 16/10
= 8/5
1.6
Step-by-step explanation:
change in y ÷ change in x
(10--6)=16
(5--5)=10
16÷10=1.6
Someone please help me thank you
slope = rise/run
rise = -3 ... move down 3 units
run = 4 .... move to the right 4 units
============================================
Work Shown:
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-17-(-2))/(24-4)
m = (-17+2)/(24-4)
m = -15/20
m = -3/4 is the slope
----------------
It basically means "move down 3 units, and move to the right 4 units"
So, slope = rise/run = -3/4
rise = -3 = move down 3 units
run = 4 = move to the right 4
You could express the slope as a decimal, and that would be -3/4 = -0.75, but you lose the rise and run values. So I recommend you keep the fraction.
Another problem with decimals is that sometimes we could have approximations that aren't exact. For example, if the slope was 2/3, then that approximates to 0.667 which may cause rounding errors down the line. Though I should point out that decimals do have their advantages in some cases.

Which expression is equivalent to 2 (t - 4) +12
Answer:
1st one I hope this helped!
Step-by-step explanation:
Answer:
2t - 7
Step-by-step explanation:
We have the expression 2(t - 4) + 1 and are asked to see which is the equivalent.
To solve, we need to first get rid of the parenthesis, which is done by distributing the number outside of the parenthesis to the numbers inside of the parenthesis :
2(t - 4) + 1
(2 * t) - (2 * 4) + 1
2t - 8 + 1
Combine like terms :
2t - 7
solve for x in each exponential equation. Round off answers to four decimal places.
Answer:
0.6875
Step-by-step explanation:
24.5 = 3.2⁴ˣ
To get the exponent out of its exponent form, we need to take the ln of both sides:
ln(24.5) = 4x · ln(3.2) - divide both sides by ln(3.2)
[tex]\frac{ln(24.5)}{ln(3.2)}[/tex] = 4x - divide both sides by 4
x = 0.6875

Branson Creek Middle School has decided to make fitness a key message to their students in the upcoming school year. As a result, they will be participating in a national fitness program. To participate, they must randomly select 15 students in the 5th grade and record their exercise time each day. The data (in minutes) are shown.
85, 80, 76, 78, 82, 88, 80, 80, 110, 85, 85, 82, 83, 88, 76
Describe the distribution of the data.
Determine the median and mean of the data.
Which measure better represents a typical value in the data set? Explain.
Answer:
data from minimum to maximum :
76 76 78 80 80 80 82 82 83 85 85 85 88 88 110
n= 15 , so the median is X8 = 82 minutes
mean =
(76+76+78+80+80+ 80 +82+ 82+ 83+ 85+ 85+ 85 +88 +88+ 110) / 15 = (1,258)/15 = 83.87 minutes
in order to get higher standard its better use mean as a typical value.

The cylinder is 20cm high and radius of its circular face is 3cm What is the total perimeter and area of the whole net?
Answer: [tex]52\ cm,\ 176.55\ cm^2[/tex]
Step-by-step explanation:
Given
The cylinder is 20 cm high
The radius of the cylinder is [tex]r=3\ cm[/tex]
The total area of the figure is the sum of the rectangle and two circles
[tex]\Rightarrow \text{Perimeter P=}2[h+2r]\\\Rightarrow P=2[20+6]\\\Rightarrow P=52\ cm[/tex]
The total area of the figure is
[tex]\Rightarrow \text{Area A=}h\times 2r+2\pi r^2\\\Rightarrow A=20\times 6+2\times \pi \times 3^2\\\Rightarrow A=120+18\pi\\\Rightarrow A=176.55\ cm^2[/tex]

In order to complete a large job, 1000 workers were hired, just enough to complete the job on schedule. All the workers stayed on the job while the first quarter of the work was done, so the first quarter of the work was completed on schedule. Then 100 workers were laid off, so the second quarter of the work was completed behind schedule. Then an additional 100 workers were laid off, so the third quarter of the work was completed still further behind schedule. Given that all workers work at the same rate, what is the minimum number of additional workers, beyond the 800 workers still on the job at the end of the third quarter, that must be hired after three-quarters of the work has been completed so that the entire project can be completed on schedule or before?
This is just here for the 20 character limit but the answer is in the picture.
