Answer: -4.5 ℉
Step-by-step explanation:
Given: On the coldest day of the year, the temperature at noon = 11℉
By midnight, the temperature had decreased by 15.5℉.
i.e. The temperature at midnight = Temperature at noon - 15.5℉
= 11℉ - 15.5℉
= (11-15) ℉
= -4.5 ℉
Hence, the temperature at midnight was -4.5 ℉.
Manny is buying new clothes for school. He buys three shirts for $14.95 each and a tie for $12. Everything in the store is on sale for 15% off. What is Manny's total cost?
Given:
Cost of each shirt = $14.95
Cost of a tie = $12
Discount on Sale = 15% off
Manny buys three shirts and a tie.
To find:
The Manny's total cost.
Solution:
We have,
Cost of 1 shirt = $14.95
Cost of 3 shirt = 3 × $14.95
= $44.85
Cost of a tie = $12
Total cost before discount = Cost of 3 shirt + Cost of a tie
= $44.85 + $12
= $56.85
Everything in the store is on sale for 15% off. So,
[tex]\text{Manny's total cost}=56.85-\dfrac{15}{100}\times 56.85[/tex]
[tex]\text{Manny's total cost}=56.85-0.15\times 56.85[/tex]
[tex]\text{Manny's total cost}=56.85-8.5275[/tex]
[tex]\text{Manny's total cost}=48.3225[/tex]
Therefore, the Manny's total cost is $48.3225.

so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)
(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7
Which is NOT true?
A 7 + 7 = 19 - 5
B 9 + 9 = 11 + 7
C 19 = 13 + 5
D 20 - 12 = 4 + 4
Answer:
C
Step-by-step explanation:
13+5=18 not 19 therefore C is not true

An artist plans a sculpture by stacking two cubes. Write an algebraic expression the artist can use to find the volume of the sculpture. Then find the volume of the sculpture when x = 4cm. *Hint: V=s3
Answer:
[tex]V= 2x^3[/tex]
The volume is 128cm^3
Step-by-step explanation:
Given
[tex]Cubes = 2[/tex]
[tex]Sides = 4cm[/tex]
Required
Determine an expression for its volume
Find the volume
Volume of a cube is:
[tex]Volume = x^3[/tex]
Where x represents the length of a side
So, volume of 2 cubes would be:
[tex]V= x^3 + x^3[/tex]
[tex]V= 2x^3[/tex]
Solving (b): Volume when x = 4
Substitute 3 for x in [tex]V= 2x^3[/tex]
[tex]V = 2 * 4^3[/tex]
[tex]V = 2 * 64[/tex]
[tex]V = 128[/tex]
Hence, the volume is 128cm^3

A line passes through the point (-4, 2) and has a slope of
Write an equation in slope-intercept form for this line.
Answer:
[tex]y=\frac{5}{4}x+7[/tex]
Step-by-step explanation:
We can start by setting up what we know of the slope-intercept equation, which is the slope.
[tex]y=\frac{5}{4}x+b[/tex]
Now, we can use the given point to find the y-intercept.
[tex]2=\frac{5}{4}(-4)+b\\ 2=-5+b\\b=7[/tex]
And now we are able to write the slope-intercept equation.
[tex]y=\frac{5}{4}x+7[/tex]

Lydia is deciding between two different movie streaming sites to subscribe to. Plan A costs $5 per month plus $2.50 per movie watched. Plan B costs $24 per month plus $1.50 per movie watched. Let A represent the monthly cost of Plan A if Lydia watches & per month, and let B represent the monthly cost of Plan B if Lydia watches x movies per month. Write an equation for each situation, in terms of x, and determine which plan would be cheaper if Lydia plans on watching 21 movies each month.
Answer:
A= 2.50x+52.50x+5
B= 1.50x+241.50x+24
Step-by-step explanation:
Plan B is $2 cheaper than Plan A when watching 21 movies.
Lydia Plan B would be 2 dollars cheaper than plan A.
Equation on each plan are:
A = 2.50x + 5
B = 1.50x + 24

What is Linear equation in one variable?
The linear equation in one variable is an equation which is represent in the form of ax + b = c, where a and b are two integers and x is a variable and has only one solution.
Here, Plan A costs $5 per month plus $2.50 per movie watched.
A = 5 + 2.50 x
here, x is movies per month.
And Plan B costs $24 per month plus $1.50 per movie watched.
B = 24 + 1.50 x
When Lydia plans on watching 21 movies each month.
x = 21
⇒ A = 5 + 2.50 (21) = 57.50
⇒ B = 24 + 1.50 (21) = 55.50
So, Lydia Plan B would be 2 dollars cheaper than plan A.

(-4,22)
Step-by-step explanation:
Answer:
(- 4, 22 )
Step-by-step explanation:
To determine which point lies on the graph, substitute the x- coordinate of the point into the equation and if the value obtained is equal to the y- coordinate of the point then it lies on the graph.
(1, - 2 )
y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 2 ← not on graph
(- 4, - 10 )
y = - 4(- 4) + 6 = 16 + 6 = 22 ≠ - 10 ← not on graph
(- 4, 22 )
y = - 4(- 4) + 6 = 16 + 6 = 22 ← lies on graph
(1, - 10 )
y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 10 ← not on graph

3. m∠A < 80°
Step-by-step explanation:
The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.
If we assume that angle measures cannot be zero, then we must have ...
m∠A +m∠N = 80°
m∠A = 80° -m∠N
Since m∠N > 0, the measure of angle A must be less than 80°.
This conclusion matches choice 3.
