In this situation, As we rise to higher attires, the temperature lowers therefore, only Option B [42. 1º. 40.5º. 39. 70. 34.49. 30.00] follows that requirement.
Now show why there are other possibilities wrong
Option A increases with the altitude, which violets the particular condition.Option C again increases at this temperature as the altitude increases and abruptly falls to 20, which is not our condition.option D up to 51.8 sounds excellent, however, this is achievable as is our given situation but the temperature goes to 59.3, therefore, this option is also refused.Learn more:

48 POINTS PLEASE HELPPPPPPP....The formula for the area of a traingle is 1/2 bh, where b is the length of base of the traingle and h is the vertical height. Use the formula to find the height of a traingle with a base length of 8 inches and an area of 39 square inches.
Answer:
h=39/4
Step-by-step explanation:
area of a triangle = 1/2(b*h)
base = 8 inches
area =39 square inches
input the values given:
39=1/2(8*h)
multiply the right side by 1/2
39=(1/2)8h
find half of 8
39=1/2*8 (h)
hence,
39=4h
divide both sides by 4
hence,
39/4=h
Cate and Elena were playing a card game. The stack of cards in the middle had 27 cards in it to begin with. Cate added 6 cards to the stack. Elena then took 10 cards from the stack. Finally, Cate took 7 cards from the stack. How many cards were left in the stack?
Answer:
16 cards were left in the stack.
Step-by-step explanation:
27 to begin with + 6 that Cate added - 10 that Elena took - 7 that Cate took.
27 + 6 - 10 - 7 = 16

i need help with numbers 15 and 18!!! what does x equal? help asap!!
Answer:
15. x = 112 degrees
18. x = 120 degrees
Step-by-step explanation:
15.
A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.
2a + 44 = 180
2a = 136
a = 68
Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.
x + 68 = 180
x = 112
18.
We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.
3a = 180
a = 60
Now we do the same thing as last time to find x.
x + 60 = 180
x = 120
Hi how can I graph this if it dosn't have a slope?
1. y = (2/3)x - 1
y = -x + 4
System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3
I hope this help you

Quincy paid $9.50 to join a photography club that allows him to print digital pictures for 0.20 each. So far he has paid $12.50 to the club. Write and solve an equation to work out how many pictures Quincy has paid for.
Answer:
9.50 + 0.20e = 12.50
Step-by-step explanation:
you start with the 9.50, base price. Then with every photo you pay 0.20, since we don't know how many it is we put a variable. Then we know that those two combined is 12.50, so yeah.
Answer:
Step-by-step explanation:
Total Cost = base price + 0.20*x Where x is the number of prints printed.
12.50 = 9.50 + 0.20x Subtract 9.50 from both sides.
12.50 - 9.50 = 0.20x
3 = 0.20x Divide by 0.20
3/0.20 = x
x = 15
So he printed 15 prints.

A recipe uses 5 cups of milk to make 30 servings. If the same amount of milk is used for each serving, how many servings can be made from one pint
Answer: 12 servings with one pint.
1 pint = 2 cups
Step-by-step explanation:
5 cups make 30 servings, 2 cups make x servings
5/30 = 2/x (cross multiplication)
(30 * 2)/5 = 12
The function represents the amount of money in a savings account that had an opening deposit of $150 and then receives a deposit of $10 every month. How much money is in the account after 1 year?
Answer:
$270
Step-by-step explanation:
The opening deposit is $150.
Every month receives $10.
In 12 months it gets 12 x $10 = $120 additional money.
So together with the opening deposit at the end of 1 year the account has
$150 + $120 = $270

m - 4 = 2m
Check your solution if possible
Answer:
m - 4m = 2m
-4 = 2m -m
- 2 = m
Answer:
m = -4
Step-by-step explanation:
Add 4 to both sides of the equation
Simplify
Add the numbers
= 2 + 4
Subtract 2 from both sides of the equation
=2+4
−2=2+4−2
Simplify
Divide both sides of the equation by the same term

Lloyd solves the equation 24x + 18(x – 2) = 216 for x. Some of his steps are shown.
Step 1: 24x + 18(x – 2) = 216
Step 2: 24x + 18x – 36 = 216
Step 3: 42x – 36 = 216
Step 4: 42x = 252
Which of the following statements BEST describes what Lloyd did to get from Step 3 to Step 4?
A.
Used the division property of equality
B.
Used the distributive property
C.

Calculate the slope of the line containing the points (6,-4) and (-1,-4).
Answer:
Step-by-step explanation:
(x₁ , y₁) = (6, -4) & (x₂ , y₂) =(-1 , -4)
In these two points, there is no change in y-coordinates. So, the line is parallel to x-axis.
Slope of line parallel to x-axis = 0
i want answer to this question
Answer:
a=1 D
Step-by-step explanation:
insert x=1 in the equation
Answer:
When it is divided by x-1 and it has no remainder , then it means substituting x=1 into the polynomial is zero .Because x-1 is a factor.
[tex]2 {x}^{3} - a {x}^{2} - 7x + 6 \\ x = 1 \\ 2 {(1)}^{3} - a {(1)}^{2} - 7(1) + 6 = 0 \\ 2 - a - 7 + 6 = 0 \\ 1 - a = 0 \\ a = 1[/tex]

Answer:
[tex] \frac{1}{15} x[/tex]
Step-by-step explanation:
[tex] \frac{7x}{20} - \frac{5x}{12} [/tex]
[tex] \frac{3 \times 7x}{3 \times 20} - \frac{5 \times 5x}{5 \times 12} [/tex]

Your cellular telephone provider offers two plans. Plan A has a monthly fee
of $15 and $0.25 per text. Plan B has a monthly fee of $20 and $0.05 per text.
Write and solve an equation to find the number of texts than you must send to
have the same cost for each of the plans.
Answer:
you must send 25 msgs to have the same cost
Step-by-step explanation:
x = n of messages
15+ (0.25x ) = 20 + (0.05x)
0.2x = 5
x = 25
Answer:
at 25 text the plan costs are equal
Step-by-step explanation:
Plan A = $15 + .25t
Plan B = $20 + .05t
when the plan costs are equal $A = $B
then
15 + .25t = 20 + .05t
.25t - .05t = 20 - 15
.2t = 5
t = 25

What is the graph of the linear inequality y≤−3x+4?
Answer:
It would look like the picture I attached at the bottom.
Step-by-step explanation:
We know that the slope is -3 and the y intercept is (0,4) (plugging in 0 for x will get you that point), and then you can just graph an equation like you normally would, using rise/run to go down 3 units for every one unit you go right, and plugging in easy x values to check your work.
It gets a little tricky because the question then adds the inequality, and we see that y is now less than or equal to the original equation.
Since it is less than, we can shade all the values below the graph.
(Also, you should probably note for future reference that if it was just less than, the shading would look the same while the graph itself would be dotted because the values on the line are nor included in the solution set).
Desmos is a great website to use if you're having trouble graphing in the future :)
