The temperature at sunrise is 35°F. Each hour, the temperature rises 7°F. Write an equation that models the temperature y, in degrees Fahrenheit, after x hours.
What is the graph of the equation?

Answer:

5

Step-by-step explanation:

4 + 7 + 5 + 4 + 8 + 2 = 30

30 ÷ 6 = 5

4+7+5+4+8+2=30

30 divided by 6=5

The algebraic equation which shows that the number of x people can go to the drive-in with one car for $19. 25 is,

[tex]5.50x+2.75=19.25[/tex]

Algebraic equation are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic equation-

The cost of going to a drive-in movie theater is $5.50 per person plus $2.75 per car. It has to create an algebraic equation that shows how many people can go to the drive-in with one car for $19. 25.

Suppose the total number of people in the car for drive-in movie theater is x. Thus, the cost of the x person to watch the movie is,

[tex]C=5.50x[/tex]

As the cost of one car is $2.75. Thus, the total cost of watching a movie by x person will be,

[tex]C=5.50x+2.75[/tex]

Now, the total cost, drive-in with one car for $19. 25. This cost must be equal to the above expression for total cost. Therefore,

[tex]C=5.50x+2.75=19.25[/tex]

Hence, the algebraic equation which shows that the number of x people can go to the drive-in with one car for $19. 25 is,

[tex]5.50x+2.75=19.25[/tex]

The completed steps to evaluate the given expression is [tex]a = 3^{-0.631} \approx 0.5[/tex]

When you raise a number with an exponent, there comes a result.

Lets say you get

[tex]a^b = c[/tex]

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

[tex]b = log_a(c)[/tex]

Some properties of logarithm are:

[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) + \log_b(c) = \log_a(c)[/tex]

The considered equation is [tex]\log_3(a) = -0.631[/tex]

[tex]\log_3(a) = -0.631\\\\a = 3^{-0.631} \approx 0.5[/tex] (from calculator).

Thus, the completed steps to evaluate the given expression is [tex]a = 3^{-0.631} \approx 0.5[/tex]

Answer:

a tin of beans costs 80p

Step-by-step explanation:

Let b = 1 tin of baked beans

80p = £0.80

Therefore, we can create an equation from the given information and solve for b:

⇒ 2.40 + 2(2.60) + 2b = 10 - 0.80

⇒ 2.40 + 5.20 + 2b = 10 - 0.80

⇒ 7.60 + 2b = 9.20

⇒ 2b = 1.60

⇒ b = 0.80

Therefore, a tin of beans costs 80p

Answer:

11

Step-by-step explanation:

A triangle has 3 sides.

Add up all the sides to get the perimeter.

So.... divide the perimeter (33) by the number of sides (3) and you get the length of each side. (11)

[tex]33/3 = 11[/tex]

We can check this by using the perimeter of a triangle formula. [tex]P = a + b +b[/tex]

[tex]P = 11+11+11[/tex]

Answer: 36

Step-by-step explanation:

Distamce from (6, 8) to (-3, 8) is 9.

Distance from (-3, 8) to (6, -4) is [tex]\sqrt{(-3-6)^{2}+(8-(-4))^{2}}=15[/tex]

Distance from (6, 8) to (6, -4) is 12.

So P = 9 + 15 + 12 = 36.

Answer:

2 : 3

Step-by-step explanation:

We have 4 squares and 6 circles. We would like the ratio of squares to circles, so we divide 4 by 6:

4 / 6  ⇒  the ratio here would be 4: 6

We need to simplify this. Notice that both 4 and 6 are divisible by 2. So, we can divide both by 2:

4/2: 6/2  ⇒  2 : 3

2 and 3 don't share any factors other than 1, so we leave the ratio like this.

The answer is thus 2 : 3.
