Answer:
d = 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁ = - 2 and a₈ = 26 , then
- 2 + 7d = 26 ( add 2 to both sides (
7d = 28 ( divide both sides by 7 )
d = 4
Answer:
d = 4
Step-by-step explanation:
a₁ = -2
a₈ = aₙ = 26
n = 8
aₙ = a₁ + d(n-1)
d = aₙ - a₁ / (n-1)
d = 26 -(-2) / (8-1)
d = 26 + 2 / 7
d = 28 / 7
d = 4
-2
-2 + 4 = 2
2 + 4 = 6
6 + 4 = 10
10 + 4 = 14
14 + 4 = 18
18 + 4 = 22
22 + 4 = 26
.The height of a cylinder whose radius is 7 cm and the curve surface area is 968 cm2 is:
Answer:
22cm
Step-by-step explanation:
Curve surface area = height x circumference.
In order to find circumference =2(pi)r
2(pi)(7)=14 pi = 44 (pretty much, rounded)
968/44=22
The height is 22cm

A square with an area of 250sq.m is inscribed in a circle. Find the diameter of the circle
Answer:
22.36 m
Step-by-step explanation:
Diagonal of the square would be the diameter of the circle.
Area of square = 250 sq m
[tex]Side \: of \: square = \sqrt{250} \: m \\ diagonal \: of \: square \\ = \sqrt{ {( \sqrt{250)} }^{2} + {( \sqrt{250)} }^{2}} \\ = \sqrt{250 + 250 } \\ = \sqrt{500} \: m \\ = 22.3606798 \: m \\ = 22.36 \: m \\ \therefore \: diameter \: of \: circle = 22.36 \: m[/tex]

Answer:
7.5% error
Step-by-step explanation:
Percent Error = ( | measured - real | / real ) x 100%
|430 - 400| / 400 = |-30| / 400
( 30 / 400 ) x 100%
= 7.5%

jordan has 3/8 pond of candy. he gave some to his brother and now he has 1/10 pound left.how much did he give to his brother
Given :
Amount of candy Jordan have , [tex]A=\dfrac{3}{8}\ pounds[/tex] .
Amount left after giving some to brother , [tex]a=\dfrac{1}{10}\ pounds[/tex] .
To Find :
How much did he give to his brother .
Solution :
Let , amount he gave to his brother is , b .
So ,
[tex]\text{Amount left = Total amount -Amount he give to his brother}\\\\a=A-b\\\\b=A-a\\\\b=\dfrac{3}{8}-\dfrac{1}{10}\\\\b=\dfrac{(3\times 10)-8}{80}\\\\b=\dfrac{22}{80}\\\\b=\dfrac{11}{40}[/tex]
So , amount he give to his brother is [tex]\dfrac{11}{40}[/tex] .
Hence , this is the required solution .

Bri wants to buy as many flip flops as she can at the store. Each flip flop costs $4 and she has $50 with her. Write an inequality to show the maximum number of flip flops Bri can buy.
Answer:
she can buy 12½flip flops
Step-by-step explanation:
it's actually easy : just do 50÷4 but then u will get something like 12.5 so if you are confused , you can divide by the closest number to 50 and the number which is a multiple of 4
so,
48÷4 = 12 and with the remaining 2 $ she can buy a half flip flop more if she wants because 4/2
Therefore , the total number of flip flops she can buy = 12½ flip flops

Solve the simultaneous equations 4x+y=10 X-5y=13
Answer: 4x + y = 10 is -y+10/4 X-5y=13 is x=5y+13
Step-by-step explanation:
The value of x and y in the equations given are -2 and 3 respectively.
What are equations?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given are two equations, 4x+y = 10 and x-5y = 13, we need to solve the equations,
4x+y = 10.......(i)
x-5y = 13
x = 13+5y......(ii)
Substituting eq(ii) in eq(i)
4(13+5y)+y = 10
52+20y+y = 10
21y = 10-52
21y = -42
y = -2
Put y = -2 in equation (ii),
x = 13+5(-2)
x = 13-10
x = 3
Hence, The value of x and y in the equations given are -2 and 3 respectively
