Find the 10th term.
Answer:
[tex]a_{10}=\frac{5^{10}}{2^7} -1[/tex]
Step-by-step explanation:
[tex]a_{n}=a_1 . r^{n}-1[/tex]
Here
[tex]r=\frac{5}{2}[/tex]
[tex]a_1 =8[/tex]
For n=10 (tenth Term)
[tex]a_{10}=8(\frac{5}{2})^{10} -1[/tex]
[tex]a_{10}=\frac{5^{10}}{2^7} -1[/tex]
David and his 2 children are going to the zoo.
The administration price is
Adult:£60
Children:£67
FAMILY DISCOUND CARD GIVES
1/5 off adults price
60% off child price
Work out the total price David pays after using his discount card.
Answer:
£92.40
Step-by-step explanation:
Discount price for David =1/5 of 60
= 1/5 × 60/1
= £12 (5 multiplied by 12 is 60)
Price for one child = £67
Price for 2 children= £67 × 2
= 134
Therefore discount price for the children,
134 × 60/100
= 134 × 6/10
= 134 × 3/5
= 26.8 × 3
= 80.4
= £80.40
Therefore total Price David pays,
£80.40 + £12
= £92.40

Mode ??
Median ??
Answer:
No mode
Median 7
Step-by-step explanation:
Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
Mode: no mode
No mode because there are no repeating numbers.
Median=7
Put in order from least to greatest- 1,6,7,42,81
Find the one in the middle- 7
3. Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk all together? Select all that apply.
A. 12 + 0.25 ⋅ 12
B. 12(1 + 0.25)
C. 12 ⋅ 1.25
D. 12 ⋅ 0.25
E. 12 + 0.25
Answer:
A, B, C
Step-by-step explanation:
12+0.25*12=12(1+0.25)=12*1.25
Answer:
B. 12 + 0.25 ⋅ 12
C. 12(1 + 0.25)
Step-by-step explanation:
It asks you how far she walks all together, so you need to find that answer first to figure out the rest correctly. Now, the total she walked is 15 miles. B. and C. give you 15, however, the rest give you different answer than the total she actually walked.

Find the equation of the line: which passes through (1,-7) and is perpendicular to (-4,6) and (5,-3)
Answer:
-9 6 that is because the line has to be perpenducular to the other line
Step-by-step explanation:
Slope of line between points (-4, 6) and (5, -3)
=> Rise / Run
=> [6 - (-3)] / [(-4) - 5]
= 9 / (-9)
= -1.
Thus slope of perpendicular line
= -1 / (-1) = 1.
We have y = x + c.
When x = 1, y = -7.
=> (-7) = (1) + c, c = -8.
Hence y = x - 8.

consider the expression 7 - 4y. Why would the co-efficient be -4 and not 4?
Because the answer to X is a negative number, and negative numbers are needed for negative answers
Answer: because it won’t make sense if it was 74y it has to have an equation or expression.
Step-by-step explanation: I’m not that smart and I have no friends on brainly but hope it helps and makes your day.

Lesson 3.3 - Calculating Slope from Graphs
Answer:
1. draw a line from the bottom left quadrant to the top right quadrant
2. draw a line from the top left quadrant to the bottom right quadrant
3. draw a horizontal line in any quadrants
4. draw a vertical line in any quadrants
5. Connect to the dots by going up to and right two. The slope will be 1.
6. Connect the dots by going up four and left two. The slope will be -2.
7. Connect the dots by going up for and right one. The slope will be 4.
8. You cannot connect the dots because it's a zero slope, so the slope is 0.

Square root 5 x square root 5 x square root 2 x square root 2
Answer left in surds
Answer:
10 or [tex]\sqrt{100}[/tex] (in surds)
Step-by-step explanation:
[tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] × [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex] = 5×2 = 10 or [tex]\sqrt{100}[/tex]
When the same square root multiply each other, they equal to the number in the square root. E.g. [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] = 5 because [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] also equals to [tex]\sqrt{25}[/tex], which is 5.
Hope this is helpful :)
Tim's pay increased by 5% to £880

Angle 4 is 65°
Step-by-step explanation:
180-115=65
Answer:
m<4 would be 65 degrees.
Step-by-step explanation:
You know they add up to 180, so 180 - 115 = 65 degrees.
In rectangle FGHJ , the diagonals intersect at point M, FM = 3.2x , and JG = 40.
What is the value of x?
Enter your answer as a decimal in the box.
Answer:
[tex]x=6.25[/tex]
Step-by-step explanation:
FM=3.2x
JG=40
Generally the diagonal of a rectangle are equal to each other and diagonal bisects each other
Therefore
[tex]2FM=JG[/tex]
[tex]2*(3.2x)=40[/tex]
[tex]x=40/6.4[/tex]
[tex]x=6.25[/tex]

Westminster Street and Lake Avenue intersect. If Westminster Street is 7 meters wide and Lake Avenue is 5 meters wide, what is the distance between two opposite corners of the intersection? If necessary, round to the nearest tenth.
Answer:
the distance between two opposite corners of the intersection is 8.60 meters
Step-by-step explanation:
The computation of the distance between two opposite corners of the intersection is given below:
Here we applied the Pythagoras theorem
[tex]= \sqrt{7^2 + 5^2} \\\\= \sqrt{49 + 25} \\\\= \sqrt{74}[/tex]
= 8.60 meters
hence, the distance between two opposite corners of the intersection is 8.60 meters
