Answer:
[tex]T(x)=84-2x[/tex]
Step-by-step explanation:
Linear Modeling
The initial temperature outside is 84 degrees.
We are told the temperature drops 2 degrees every hour.
Let's call x to the number of hours elapsed. After x hours, the temperature would have dropped by 2x degrees, since it's a rate of 2 degrees per hour.
That drop is subtracted from the initial temperature to produce the linear model as follows:
[tex]\mathbf{T(x)=84-2x}[/tex]
This is the linear equation that represents the described situation.

if m=2 and n=-5
find the value of
m+n
5m-2n
n^m
Answer:
1.) -3
2.) 20
3.) is either - 25 or just 25 (depends if you have parentheses around the -5)
Step-by-step explanation:
2.) 5*2 is 10
2*-5 is -10
10-(-10) =20
3.) parentheses: (-5)^2 = 25
w/o parentheses: -5^2 = -25

What is the eighth term in the following sequence?
2, 4, 8, 16.....
132
I can’t figure this out?
Answer:
256
Step-by-step explanation:
Each term is being multiplied by 2 on the previous term, so the 8th term will be 256 if you keep multiplying by 2.

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.
so, x = 17 (isosceles triangle)
then use pythagoreas theorem:
[tex]y = \sqrt{x {}^{2} + 17 {}^{2} } [/tex]
and x = 17, so simplify and
[tex]y = \sqrt{17 {}^{2} + 17 {}^{2} } [/tex]
so
[tex]y = 17 \sqrt{2} [/tex]
In 2001, 32 out of 80 members of New Jersey's House of Representatives were Democrats and 25 out of 60 members of Oregon's House of Representatives were Democrats. For each state, write a fraction for the number of Democrats in the House to the total number of House members. Which state had a greater fraction of Democrats in its House of Representatives?
Answer: Oregon
Step-by-step explanation:
For New Jersey:
Number of house of Representatives members = 80
Number of Democrats = 32
Fraction = 32/80 = 2/5
For Oregon:
Number of house of Representatives members = 60
Number of Democrats = 25
Fraction = 25/60 = 5/12
The state that has a greater fraction of Democrats in its House of Representatives is Oregon. This is because 5/12 is greater than 2/5.
Find the value of x. Round to the nearest tenth
7 and 9
Answer:
x=5.7
Step-by-step explanation:
a^2+b^2=c^2
7^2+b^2=9^2
49+b^2=81
b^2=32
b=5.7
Answer:
b=5.7
Step-by-step explanation:
a^2+b^2=c^2
7^2+b^2=9^2
49+b^2=81
b^2=32
b=5.7
Find the rate of discount when M_P=Rs 2500 and S.P =Rs_2350 The price of a T. V set inclusive of sales tax is RS 33660_If the rate of sales tax is 10% find its basic price.
Answer:
Step-by-step explanation:
The question is in two parts
For the first part;
Mark up price = 2500
Selling price = Rs 2350
To get the discount rate we will use the expression
Discount = MP-SP/MP× 100
Discount = 2500-2350/2500 × 100
Discount =150/2500 × 100
Discount percent = 150/25
discount percent = 6%
For the second part;
Cost of TV = Rs 33660 (including tax)
Sales tax = 10%
Increment = 10% of 33660
Increment = 0.1×33660
Increment = Rs 3366
Basic price = sales price (including tax)-increment
Basic price = 33660-3366
Basic price = Rs 30,294

A water tank already contains 55 gallons of water when Baxter begins to fill it. Water flows into the tank at a rate of 8 gallons per minute. Write a linear equation to model this situation. How long it will take to get 127 gallons of water
Answer: 8x+55=127
Step-by-step explanation: it would take 9 mins because there’s already 55 gallons of water in the tank so you subtract that from 127 which is 72 then you divide 72 by 8 and get 9
Write a linear function g with g(0) = 9 and g(8) = 7.
Answer:
4y = 36-x
Step-by-step explanation:
A linear function is in the form
y = mx + b
for g(0) = 7 ;
x = 0 and y = 9
So ;
9= 0(x) + b
b = 9
For g(8) = 7
x = 8 and y = 7
7 = 8m + 9
7-9 = 8m
8m = -2
m = -2/8 = -1/4
So the equation is;
y = -1/4x + 9
Multiply through by 4
4y = -x + 36

Brian drives a distance of 250 m at a speed of 50 m/sec. With what speed should he
drive so that he covers twice the distance in the same time?
2 Marks
Answer:
100 m/s
Step-by-step explanation:
This can be done without a formula
If you think about it, as you walk faster you cover more distance (taking the same duration)
So if you double your velocity, you will double the distance you cover

Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens! Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9A a few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
Given :
Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9 sign a few weeks from now.
Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
To Find :
Least possible number of times that Miranda has been to the store.
Solution :
It is common to see that :
7 dollar/visit ×9 visits = $63
9 dollar/visit ×7 visits = $63
Therefore, minimum number of times Miranda has been to the store is 9.
Hence, this is the required solution.
Answer: 9 times

If T is the circumcenter of MNP, find the indicated measure:
Find MN
Answer:
MN = 55
Step-by-step explanation:
Since T is the circumcenter of ∆MNP, it follows that the perpendicular bisector of side MN divides MN into two equal parts.
Therefore:
MR = RN
MR = 10x -13
RN = 17x - 41
Thus:
10x - 13 = 17x - 41
Collect like terms
10x - 17x = 13 - 41
-7x = -28
Divide both sides by -7
x = 4
MR + RN = MN
(10x - 13) + (17x - 41) = MN
Plug in the value of x
(10(4) - 13) + (17(4) - 41) = MN
(40 - 13) + (68 - 41) = MN
27 + 27 = MN
54 = MN

The problem has been started for you. 8 StartLongDivisionSymbol 468 EndLongDivisionSymbol minus 40 = 68. 68 minus 64 to get a remainder of 4 and a quotient of 58. What is the quotient?
Answer:
Quotient = 58
Step-by-step explanation:
We are to find the quotient of the expression using long division method. This is as shown in the attachment.
The expression is expressed as;
468/8
This can be expressed as ;
468/8 = 58 + 4/8
Note that according polynomials are expressed as;
P(x) = Q(x) + R(x)/D(x)
Where;
Q(x) is the quotient
R(x) is the remainder
D(x) is the divisor
Comparing with the expression 58 4/8, you will see that Q(x) is 58.
Hence the quotient when 8 is divided by 468 is 58.
