The temperature varies indirectly as the distance from the city. The temperature equals 5°C when the distance from the city is 50 miles. What is the temperature when the distance is 20 miles from the city?
Answer:
2 degrees c
Step-by-step explanation: It's 5 degrees when it's 50 miles, simplify that and you get 1 degree c when it's 10 miles, so 1 times 2 is 20 and 1 times 2 is 2
The graphs with the equation 3y + x = 1/2 and 9y - 21x = -621/10 have been drawn on the grid.
Answer:
X= 2.61
Y= -0.7
Step-by-step explanation:
The estimates of the solutions of the simultaneous equations given are x = 2.65 and y = -0.71.
Given a graph of the two equations:
3y + x = 1/2
9y - 21x = -621/10
These simultaneous equations can be solved and find the solution algebraically by substitution or elimination methods.
Here, it is required to find the solution using the graphs.
Already, the graphs of the two equations are given.
The solution of the two equations graphically can be found by the intersecting point of those graphs.
Here the two graphs intersect at :
x value in between 2.6 and 2.7.
y value close to -0.7.
So the solution can be estimated as x = 2.65 and y = -0.71.

Megan has 99 photos on her phone. John has p photos on his phone. If Megan has 9 times as many photos on her phone as John, write and solve an equation to find how many photos John has on his phone can someone help plssss
Answer:
John has 11 photos on his phone
Step-by-step explanation:
Equations
Megan has 99 photos on her phone and John has p photos on his phone. It's given Megan has 9 times as many photos on her phone as John has. This leads to the following equation:
99 = 9p
Dividing by 9:
p = 99/9 = 11
John has 11 photos on his phone
Sue started the day with $260 in her bank account.She purchased 15 books that we're all the same price.After she left the store,she had -$10 in her account.How much did each book cost?
Answer:
$18
Step-by-step explanation:
Since she ended up with -$10 in her account after leaving the store, that means that she spent $270 at the store total.
Since the books were the same price, just divide.
270/15=18
This means that each book cost $18

OAB is a sector of a circle with centre O and radius 8 cm.
Angle AOB = e°
The area of the sector is 58 cm2
Calculate the perimeter of the sector.
Give your answer correct to 3 significant figures.
Answer:
The perimeter of the sector is :30.5 cm
Step-by-step explanation:
Mathematically, we have the area of the sector as;
e/360 * pi * r^2
r is 8 cm
so we have
58 = e/360 * pi * 8^2
58/64 * 360/pi = e
e = 103.85
To get the perimeter,
we have length of the arc plus 2r
Length of the arc is;
e/360 * 2 * pi * r
add 2 r;
e/360 * 2 * pi * r + 2r
so we have
103.85/360 * 2 * pi * 8 + 2(8)
= 14.5 + 16
= 30.5 cm

LCM of two numbers is 1320 their HCF is 12 if one of the numbers is 132 find the other
Answer:
brainliest plzzzzzzzz
120
Step-by-step explanation:
LCM=1320
(GDC) HCF=12
Another no.=132
let second no. be =A
According to question
First no.×Second no.=HCF×LCM
132×A=12×1320
132×A=15840
A=15840/132
A=120
Other no. is 120
6 m from the pole from base of a telephone pole and 10 m to reach the top of the pole how tall is the telephone pole
Answer:
8m
Explanation
The set up is a right triangle
Given
The distance of pole from the base = 6m
Length of the pole = 10m
Required
Height of the telephone pole h
Using the pythagoras theorem;
hyp^2 = opp^2 + adj*2
10^2 = 6^2 + h^2
h^2 = 10^2 - 6^2
h^2 = 100 - 36
h^2 = 64
h = √64
h = 8m
Hence the height of the telephone pole is 8m
