The temperature in Greenland was -12°. For 4
hours the temperature rose 3º every hour.
What was the temperature after 4 hours?
Please help me with this math problem

Answer:

The answer is -21

Step-by-step explanation:

0.5(5 - 7x) = 8 - (4x + 16)

2.5 - 3.5x = 8 - 4x - 16

3.5x - 2.5 = 4x - 8 + 16

3.5x - 4x = 2.5 - 8 + 16

-0.5x = 10.5

x = 10.5/(-0.5)

x = -21

Thus, The answer is -21

Step-by-step explanation:

[tex]\huge\mathcal\pink{here's your solution} \\ \\ 0.5(5 - 7x) = 8 - (4x + 16) \\ \\ 2.5 - 3.5x = 8 - 4x - 16 \\ \\ - 3.5x + 4x = - 8 - 2.5 \\ \\ 0.5x = 10.5 \\ \\ x = 10.5 \div 0.5 \\ \\ x = 21 \\ \\ \huge\mathfrak\purple{hope \: it \: helps..}[/tex]

Answer:

She has to pay an extra $3,000

Step-by-step explanation:

36 months is 3 years. She is allowed 5,000 miles per year, so 3 x 5,000 = 15,000 miles allowed. But she drove 25,000.

25,000 - 15,000 = 10,000 extra miles

10,000 x 0.30 cents/mile = 3,000

Skyler have to pay for 10000 miles the amount is $3000.

A equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Skyler leased a car for 36 months.

Her contract said she can drive 5,000 miles per year and will have to pay $0.30 per mile above the allowance.

If she turns in the car after her lease term with 25,000 miles driven.

There are 12 months in a years so in 36 months,

[tex]=\dfrac{36}{12}\\\\=3 \ \rm years[/tex]

There are 3 years in 36 months.

Her contract said she can drive 5,000 miles per year, so in 3 years he drives the car;

[tex]\rm = 5000\times 3\\\\=15000 \ miles[/tex]

If she turns in the car after her lease term with 25,000 miles driven, how much will Skyler have to pay for the extra miles is;

= 25000 - 15000

= 10000

He has to pay extra amount for 10,000 miles which is;

[tex]= 10000\times 0.30\\\\= 3000[/tex]

Hence, Skyler have to pay for 10000 miles the amount is $3000.

Answer:

[tex](-2, -6)[/tex]

Step-by-step explanation:

The reflection over the line [tex]y=-1[/tex] will only affect the y-coordinate. Since the initial coordinate [tex](-2, 4)[/tex] is 5 units directly above the line [tex]y=-1[/tex], the reflection over will result in the new y-coordinate being 5 units directly below [tex]y=-1[/tex]. Thus, the coordinates of [tex]B'[/tex] are [tex](-2, -6)[/tex].

Answer:

The probability of marble getting marked as 6 is 0.9

Step-by-step explanation:

Total number of marbles = 10

The probability is the ratio of the number of elements in the event to the number of elements in the sample space.

Here the number of elements in the sample space = 10

The probability of getting a marble marked as 6 is

[tex]P(E)=\frac{1}{10}[/tex]

The probability of not getting the marble marked as 6 is

[tex]P((E')=1 - P(E)\\P(E') = 1- 0.6= 0.4[/tex]

[tex]P(E') = \frac{9}{10}[/tex]

Answer:

2

Step-by-step explanation:

First you need to factor your quadratic equation. You'll get (2x+1)(2x+1). Your two zeroes will be -1/2 and -1/2 with one being a, the other b. So then

a/b = (-1/2)/(-1/2)

and

b/a = (-1/2)/(-1/2)

Both reduce to 1. So a/b + b/a is 1+1=2

Answer:

Tthe length of AB is 13.6 cm

Step-by-step explanation:

Step 1: calculate length CD using the area of a triangle

[tex]A = \frac{1}{2} \times (AD \times CD) \times \ sine (D)\\\\52 = \frac{1}{2} \times (12 \times CD) \times \ sine (102)\\\\52 = 6CD \times 0.978\\\\52 = 5.868CD\\\\CD = \frac{52}{5.868} \\\\CD = 8.862 \ cm[/tex]

Step 2: calculate length AC using Cosine rule;

[tex]AC^2 = AD^2 + CD^2 - 2(AD \times CD)cos (D)\\\\AC^2 = 12^2 + 8.862^2 - 2(12 \times 8.862)cos(102)\\\\AC^2 = 222.535 - 2(-22.11)\\\\AC^2 = 222.535 + 44.22\\\\AC^2 = 266.755\\\\AC = \sqrt{266.755} \\\\AC = 16.33 \ cm[/tex]

Step 3: Apply sine rule to calculate length AB;

[tex]\frac{AB}{sin \ 46} = \frac{AC}{sin \ 120} \\\\AB = \frac{sin \ 46 \ \ \times \ \ AC}{sin \ 120} \\\\AB = \frac{sin \ 46 \ \ \times \ \ 16.33}{sin \ 120} \\\\AB = 13.56 \ cm \\\\AB = 13.6 \ cm[/tex]

Therefore, the length of AB is 13.6 cm

Answer:

  an = 243·(1/3)^(n-1) = 3^(6-n)

Step-by-step explanation:

This geometric sequence has a first term of a1=243 and a common ratio of r = 81/243 = 1/3. The general term for it is ...

  an = a1·r^(n-1)

  an = 243·(1/3)^(n-1)

Making use of the rules of exponents, this can be simplified to ...

  an = 3^5·(3^-1)^(n-1) = 3^(5-n+1)

  an = 3^(6-n)
