Answer:
18 degrees
Step-by-step explanation:
When Mr. Davidson preheated his oven, the oven's temperature rose 3 degrees in 1/ 6 of a minute. At that rate, how much will the oven heat up in 1 minute?
Solving the above question
1/6 minute = 3 degrees
1 minute = x
Cross y
1/6x = 3 × 1
x = 3 ÷ 1/6
x = 3 × 6
x = 18 degrees
The oven will heat up 18 degrees in 1 minute

The equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2
How to determine the function g(x)?The equation of the function f(x) is given as:
f(x) = x^3
The function g(x) is shifted down by 2 units and shifted left by 3 units, to get the function g(x)
This means that:
g(x) = f(x + 3) - 2
So, we have:
g(x) = f(x + 3) - 2
Hence, the equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2

Answer:
A
Step-by-step explanation:
The bottom side of the smaller rectangle is marked 10, and the bigger one is marked 20. 20÷10=2, making this a 2:1 scale. Simply multiply the 8 on the right of the smaller rectangle by 2 and you'll get 16, the answer for the similar rectangle.
Answer:
A. 16 cm
Step-by-step explanation:
Since the rectangle on the left is 10 cm and the one on the right is 20, that means that it was multiplied by 2. So you multiply 8 by 2 and you get 16.
Triangles J K L and M N R are shown.
In the diagram, ∠J ≅ ∠M and JL ≅ MR. What additional information is needed to show ΔJKL ≅ △MNR by SAS?
KL ≅ NR
∠L ≅ ∠R
∠K ≅ ∠N
JK ≅ MN
Answer:
JK ≅ MN
Step-by-step explanation:
SAS states that any two sides of the angle and the angle itself, if , of two triangles are equal the two triangles are equal.
It is given that ∠J ≅ ∠M and JL ≅ MR i.e an angle and a side are equal. We need one more side to prove that the two triangles are equal.
If we look at the diagram closely we see that the angles J and M are formed by the sides JK & JL and MN& MR.
It is given that JL ≅ MR so we are left with JK ≅ MN
The additional information needed prove that ΔJKL ≅ ΔMNR by SAS Congruence Theorem is: D. JK ≅ MN
Recall:
The SAS Congruence Theorem proves that two triangles are congruent to each other if they have two pairs of congruent sides and a pair of included congruent angles.The image attached below shows ΔJKL and ΔMNR where we are given the following:
∠J ≅ ∠M (one pair of congruent angles).
JL ≅ MR (one pair of congruent sides).

actually answer this
Answer:
1. isosceles
2. Right
Step-by-step explanation:
Here, we want to give the kind of triangle in each of the diagrams
1. From what we can see, we have two sides equal to each other using the given markings. More specifically, the base sides are equal and that makes the triangle an isosceles triangle
2. From what we can see here, we have an angle of 90 degrees on one of the sides of the triangle. In other words, we have a right angle on one of the sides.
This makes the triangle, a right triangle
Given f(x)=2x²+2x-4, which is correct?
A) f(0)=0
B) f(-1)=4
C) f(b+1)=2b²+6b-4
D) f(a)=2a²+2a-4
Answer:
Option D: f(a) = 2a²+2a-4 is the correct answer.
Step-by-step explanation:
Given that:
f(x)=2x²+2x-4
We will check the function at the given value;
A. f(0)
Putting x=0 in given function
f(0) = 2(0)²+2(0) - 4
f(0) = 0+0-4
f(0) = -4
B. f(-1)
Putting x=-1
f(-1) = 2(-1)²+2(-1)-4
f(-1) = 2(1) -2-4
f(-1) = 2-6
f(-1) = -4
C. f(b+1) = 2b²+6b-4
Putting x=b+1
f(b+1) = 2(b+1)²+2(b+1)-4
f(b+1) = 2(b²+2b+1)+2b+2-4
f(b+1) = 2b²+4b+2+2b+2-4
f(b+1) = 2b²+6b
D. f(a) = 2a²+2a-4
Putting x=a
f(a) = 2(a)²+2(a)-4
f(a) = 2a²+2a-4
Hence,
Option D: f(a) = 2a²+2a-4 is the correct answer.

Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). What are the coordinates of point B?
Step-by-step explanation:
Let (x, y) be the coordinates of point B.
(4, 6) => (-2, 4) => (x, y)
We have 2(-2) = 4 + x and 2(4) = 6 + y.
Solving these, we get x = -8 and y = 2.
Hence the coordinates of point B is (-8, 2).
Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). Hence the coordinates of point B will be (-8, 2).
What are the coordinates of the midpoint of the line segment AB?Suppose we've two endpoints of a line segment as:
A (p,q), and B (m,n)
Then let the midpoint be M(x,y) on that line segment.
Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}[/tex]
and
[tex]y = \dfrac{q+n}{2}[/tex]
Let (x, y) be the coordinates of point B.
Q has coordinates of (-2, 4).
A has coordinates of (4,6).
A (p,q) = (4, 6)
M(x,y)= (-2, 4)
B = (x, y)
We have
2(-2) = 4 + x
2(4) = 6 + y.
Solving these, we get
x = -8 and y = 2.
Hence the coordinates of point B will be (-8, 2).

Using the English alphabet. which consists of 21 consonants and 5 vowels, how many three-letter arrangements can be made in which the first letter is a consonant, the second letter is a vowel and the third letter is a consonant
Answer:
They are plenty
Step-by-step explanation:
Answer:
2205
Step-by-step explanation:
Letter 1 is a consent, so there are 21 choices for the letter (all 21 consonants).
Letter 2 is a vowel, so there are 5 choices (all 5 vowels).
Letter 3 is a consent so there are 21 choices (all 21 consonants).
One would have to do 21 * 5 * 21 to find the number of combinations which fit these criterias.
21 * 5 * 21
= 2205
This is disregarding all the other rules of English grammer and word strucutre, so the total amount of combinations that can be found would include nosensical words. The total number of words would also include repeating consonants, so a consonant can appear twice in a combination, and some combinations might repeat.

The area of base of prism is literally the area of the base part of the prism. In this case, its a triangular prism so its base is a Triangle. You can find base area of 1st figure by using 1/2 ×perpendicular×base of right angled triangle whereas on 2nd and 3rd figure you can use 1/2 ×height×base of Triangle.
The volume of Prism is given by base area ×height of the prism, so you can easily find it.

At the movies, a couple bought 2 medium drinks and a large popcorn for $13.85. At the same theater, a family bought 3 medium drinks and 2 large popcorns for a total of $23.90. What is the cost of a medium drink?
Answer:
$3.8
Step-by-step explanation:
What is the cost of a medium drink?
Let medium drinks = x
Large popcorn = y
At the movies, a couple bought 2 medium drinks and a large popcorn for $13.85.
2x + y = 13.85...Equation 1
y = 13.85 - 2x
At the same theater, a family bought 3 medium drinks and 2 large popcorns for a total of $23.90.
3x + 2y = 23.90.... Equation 2
Substitute y = 13.85 - 2x
3x + 2(13.85 -2x) = 23.90
3x + 27.7 - 4x = 23.90
3x - 4x = 23.90 - 27.7
-x = -3.8
x = $3.8
Since x = medium drink, the cost of a medium drink = $3.8
