Elisha recorded the temperature for 5 days. When he added thr 5 temperatures together he got a sum of -7.4 c.If he recorded these numbers: -8.1 c , -7.4 c, 5.5 c, 6.2 c but was missing 1 record, what was the missing temperature?

A. -8.1 c
B. -3.6 c
C. -1.9 c
D. 2.3 c

Answers

Answer 1

Answer:

B. -3.6 c

Step-by-step explanation:

Answer 2
ANSWER:
B. -3.6 c

WORK:
7.4 = (-8.1) + (-7.4) + (5.5) + (6.2) + ?

? = -7.4 - [(-8.1) + (-7.4) + (5.5) + (6.2)]
? = -7.4 - (-3.8)
? = -7.4 + 3.8
? = -3.6

The formula V=R-N describes the variation V of the recorded temperature R from the normal temperature N. If the recorded temperature is -4.6 degrees F and the normal temperature is 3.2 degrees ​F, what is the variation from the normal​ temperature?

Answers

Answer:

-7.8

Step-by-step explanation:

We will substitute the recorded temperature (-4.6) in the “R” (in the formula) and we will substitute 3.2 in the normal temperature “N”. So you should have V= -4.6 - 3.2 (negative Four point six subtracted by three point two) then solve. This should give you -7.8. Remember your integers!

Parker runs a farm stand that sells strawberries and peaches. Each pound of strawberries sells for $1 and each pound of peaches sells for $1.50. Parker sold 3 times as many pounds of strawberries as pounds of peaches and he made $54 altogether. Graphically solve a system of equations in order to determine the number of pounds of strawberries sold, x,x, and the number of pounds of peaches sold, yy.

Answers

Answer:

12 peaches, 36 strawberries

Step-by-step explanation:

let's say he sold x peaches, so 3x strawberries

3x + 1.5x = 54

4.5x = 54

x = 12

12 x 3 = 36

A value  Parker runs a farm stand that sells strawberries and peaches. Parker sold 36 pounds of strawberries and 12 pounds of peaches

Let's denote the number of pounds of strawberries sold as "x" and the number of pounds of peaches sold as "y".

Each pound of strawberries sells for $1.

Each pound of peaches sells for $1.50.

We also know that Parker sold 3 times as many pounds of strawberries as pounds of peaches:

Equation 1: x = 3y

And the total amount made was $54:

Equation 2: 1x + 1.5y = 54

these equations to find the point of intersection, which represents the solution:

Equation 1: x = 3y

Equation 2: 1x + 1.5y = 54

First, we'll rearrange Equation 1 to solve for y: y = x/3.

Now, let's substitute this value of y into Equation 2:

1x + 1.5(x/3) = 54

1x + 0.5x = 54

1.5x = 54

x = 36

The value of x find y using the equation y = x/3:

y = 36/3

y = 12

These equations to visually confirm the solution:

x-axis: Pounds of strawberries (from 0 to 40)

y-axis: Pounds of peaches (from 0 to 20)

Plot the line y = x/3 (this represents the relationship x = 3y), and plot the line 1x + 1.5y = 54. The point where these lines intersect is the solution (36, 12).

Solve Equations by Substitution
f
Determine whether the given value for the variable is the solution to the equation.
2n+5=27; n=11
Substitute the value for the variable.
2⋅11+5=?27
The value for n is 11, so replace n with 11.

Think About ItWhy does the equals sign have a question mark above it?

While the expression on the left has a variable, the expression has no value. Once we replace the variable with a number, the expression immediately has a value. Until we simplify that expression, we don’t know what this value is and whether or not it’s the same value as the expression on the right. Therefore, we place a question mark over the equals sign to show that we don’t know whether the expressions are equal.
Simplify.
2⋅11+5=?27
22+5=?27
27=27
The left side of the equation has an expression that must be simplified. Follow the order of operations. First, multiply 2 by 11 to get 22. Then, add 22 and 5 to get 27. Since the expression on the left is the same as the expression on the right, the expressions are equal.

Conclude.
n=11 is the solution to the equation.

Since substituting 11 for n resulted in the expression on the left equaling the expression on the right, 11 is the solution to the equation.

Write in slope-intercept form an equation of the line that passes through the points (−4, 2) and (6,−3).


y=

Answers

Answer:  

y = [tex]-\frac{1}{2}[/tex]x  

Step-by-step explanation:  

Slope-intercept form: y = mx + b  

    [] m is the slope  

    [] b is the y-intercept  

Slope  

We can find slope by using change in y over change in x:

[tex]\frac{-3-2}{6--4}=\frac{-3-2}{6+4} =\frac{-5}{10} =\frac{-1}{2}[/tex]  

    [] So our slope is [tex]-\frac{1}{2}[/tex]    

Y-intercept  

We will plug in one of the points into our equation so far, and solve for b:  

    y = [tex]-\frac{1}{2}[/tex]x + b  

    (2) = [tex]-\frac{1}{2}[/tex](-4) + b  

    2 = 2 + b

    0  = b

Okay so the relationship is that when you divide the cost by pounds so $8.58 divided by 2 you get $4.29. This also happens when you divide $17.16 by 4 you get $4.29 you also can see that when you divide $25.74 by 6 you will also get $4.29. I hope I was a little help. The relationship is $4.29 and you get that when you divide the cost by pounds.

Which situation can be represented by this inequality?

135 ≤ 10r + 15

Question 8 options:

A Hugo has 10 songs in his music player. He will add 15 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at most 135 songs?


B Hugo has 10 songs in his music player. He will add 15 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?


C Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at most 135 songs?


D Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?

Answers

Answer:

D

Step-by-step explanation:

So the key to figuring this equation is writing it out. If Hugo already has 15 songs, then he will add 15 at the end for his collection. If he gets 10 every month, for r months, you must multiply them for 10r. You do this because you get 10 for r, the amount of months. This is where you add the 15, since it is your collection total.

so far we have 10r + 15

For teh last part we see that the equation, 135 ≤ 10r + 15, says that 135 is less than or equal to our 10r +15. This means that D has to be the answer since nothing else will fit.
