If the temperature outside was 63°F at 5:00 p.m., but it fell 21 degrees by 10:00 p.m., what is the temperature at 10:00 p.m.?
Answer:
42°
Step-by-step explanation:
Subtract: 63 - 21 = 42°
Answer:
42°F
Step-by-step explanation:
63-21=42°F
if it fell, it means it went down, so it got colder
Which expressions are equivalent?
a) 1/5k-2/3j and -2/3+1/5k
b) 1/5k-2/3j and -1/5+2/3j
c) 1/5k-2/3j and 1/5j-2/3k
d) 1/5k-2/3j and 2/3j-1/5k
PLEASE HELP
Answer:
The answer should be A
Step-by-step explanation:
Because 1/5k - 2/3j would be -2/3 j with 1/5 k missing which would mean it's the same as if you added it on instead of removing it
Answer:
A

Which pairs of expressions are equivalent? Select all that apply.
A
-4 - 7 and -4 + (-7)
B
16 - 7 and -16 + 7
C
-7 - (-12) and -7 + 12
D
-2 - 3 and 2 + 3
E
10 - 2 and 10 - (-2)
Answer:
A & C
-4-7=-11 and -4+(-)=-11
-7-(-12) and -7+12
Step-by-step explanation:
-4-7= -11, -4+ (-7)= -11
-7-(-12) turns into -7+12=5
the second equation is the same as the first (after using PEDMAS), resulting in the answering being -7+12=5
The pairs of expressions that are equivalent will be -4 - 7 & -4 + (-7) and -7 - (-12) & -7 + 12. Then the correct options are A and C.
What is an equivalent?The equivalent is the expression that is in different forms but is equal to the same value.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Check all the options, then we have
A. -4 - 7 and -4 + (-7), then we have
-4 - 7 = - 4 + (-7)
B. 16 - 7 and -16 + 7, then we have
16 - 7 ≠ - 16 + 7
C. -7 - (-12) and -7 + 12, then we have
- 7 - (-12) = - 7 + 12
D. -2 - 3 and 2 + 3, then we have
- 2 - 3 ≠ 2 + 3
E. 10 - 2 and 10 - (-2), then we have
10 - 2 ≠ 10 - (-2)
The pairs of expressions that are equivalent will be -4 - 7 & -4 + (-7) and -7 - (-12) & -7 + 12. Then the correct options are A and C.

Part A: what is the measure of QRS?
Part B; what is the measure of Q?
Answer:
QRS = 66° and Q = 95°
Step-by-step explanation:
Required Answer
[tex]\huge {\boxed{\sf{∠QSR=66⁰}}}[/tex]
[tex]\huge {\boxed{\sf{∠Q=95}}}[/tex]
Correct Question:
To find of :
∠QSR∠QExplanation:
∠QSR+∠QRT=180⁰
Reason:
linear pair
.°. ∠QSR+114⁰=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
Can also be done as follows:
To find value of ∠QSR first we have to find y
y⁰+(5y)⁰=114
Reason:
exterior opposite angle is equal to sum of interior angles
6y=114
y=114/6
y=19
y⁰+(5y)⁰+∠QSR=180⁰
Reason:
sum of angles of triangle =180⁰
6y+∠QSR=180⁰
6×19+∠QSR=180⁰
114+∠QSR=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
From second part we get the value of y

What is 2M?
M=[3 5]
[-4 0]
Answer:
2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Step-by-step explanation:
Given the matrix
[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]
Multiplying by 2 will basically be a scalar multiplication.
Therefore, multiply each of the matrix elements by a scalar.
[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Hence, 2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Line m contains the points (−3, 2) and (5 , 1). Line n contains the points (2 , 7) and (1, −1) . Which statement is TRUE about lines m and n?
A. The lines are parallel.
B. The lines are coincident.
C. Both lines intersect but are neither parallel nor perpendicular.
D. The lines are perpendicular.
9514 1404 393
Answer:
D. The lines are perpendicular
Step-by-step explanation:
The first line has a rise of (1-2) = -1 for a run of (5-(-3)) = 8.
The second line has a rise of (-1-7) = -8 for a run of (1-2) = -1.
Then the slopes are -1/8 and -8/-1 = 8, which are negative reciprocals of each other. Lines with slopes having that relationship are perpendicular.

Answer:
-1/10 for first one and -4/2 for second one
Step-by-step explanation:
lol can I have brainliest?
Hello!
Okay, so: To find the slope, you can use the slope formula: y2-y1/x2-x1...
Let's begin.
Start by plugging in given values into the formula. We can see from looking at the chart that,
y2 = -2
y1 = 3
x2 = 2
x1 = -8
Those are for set 1. So, Let's plug these values into the slope formula:
-2 - 3/2 - (-8)
Subtract
-5/10
Now divide
-1/2 or -0.5
Okay, now let's move on to Set 2.
Set 2:
We're going to do the exact same thing here that we did earlier. Given from the chart:
y2 = -3
y1 = -1
x2 = -2
x1 = 4
Plug them into the formula:
-3 - (-1) / -2 - 4
Subtract
-2 / -6
Divide
1/3
So, for set 1, the slope is -1/2. For set 2, the slope is 1/3.

The cost of renting Party Palace is $ 120 plus $ 15 per person attending the party. If the total cost of renting Party Palace is $ 480 , how many people attend the party?
Answer:
24 individuals
Step-by-step explanation:
Since we are given the actual costs as well as the final total then we can calculate the total number of people that attended the party by doing the following. We first subtract the fixed cost of $120 by the total cost of the party, and then we divide the remainder by the cost per person, which would give us the number of people who attended (x) ...
($480 - $120) / $15 = x
$360 / $15 = x
24 = x
Finally, we can see that a total number of 24 individuals attended the party

f(x) = 3x + 5
g(x) = 4x^2 – 2
h(x) = x^2 – 3x + 1
Find f(x) – g(x) – h(x).
Answer:
f(x) – g(x) – h(x) = -5x^2 + 6x + 6
Step-by-step explanation:
Copy f(x) as is: f(x) = 3x + 5
Negate g(x): -g(x) = -4x^2 + 2
Negate h(x): -h(x) = -x^2 + 3x - 1
Now combine like terms:
f(x) – g(x) – h(x) = -5x^2 + 6x + 6

The volume of the large cube is 125 cubic inches. The volume of the small cube is 27 inches. What is the difference between the length of one side of the large cube and the length of one side of the small cube?
Answer:
2cmStep-by-step explanation:
Step one:
given data
for the large cube
the volume= 125cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
125=l^3
l=∛125
l=5cm
Step two:
given data
for the large cube
the volume= 27cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
27=l^3
l=∛27
l=3cm
The difference between the length of one side of the large cube and the length of one side of the small cube=5-3= 2cm
