What is the change for each consecutive input?
✔ 1
What is the change for each consecutive output?
✔ 0.35
What is the rate of change for the relationship?
✔ 0.35
Step-by-step explanation:
The change for each input is 1 beacause the inputs are 10,11,12,13
The change for each consecutive output is 0.35 beacuse we need to subtract 4.1 from 3.75
The rate of change for the relationship is also 0.35

Nadine promised to meet her friend at a store but she forgot which store. There are five
stores in town. What is the probability that Nadine will go to the right store first?
B
0.20
A
0.16
D
1.00
С
0.80
Answer:
.2 chance of going to the right store
Step-by-step explanation:
Five stores, and she is to meet a friend at one. One store is the right one so it is 1 out of 5, or 1/5. This equals 20%
In decimal it is a .2 chance of Nadine going to the right store

What is the value of x?
Answer:
B. 85*
Step-by-step explanation:
1. Understand that a triangle always has the additive degrees of 180.
2. Use x+55+40=180, to isolate x, subtract 55 and 40 from 180.
3. You get x = 85.
Answer:
B. 85 degrees
Step-by-step explanation:
According to the Triangle Sum Theorem, all the angles inside a triangle equal 180 degrees. The work is below:
180-40-55=85. The angle missing is 85 degrees.

when x increases from a to a +2, y increases by a factor of 1/4
Answer:
y=7* (0.5)^x
Step-by-step explanation:
We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.
i.e. when x=a and x'=a+2.
then y/y=0.25 where y' is the function after putting x' to the old function.

The measure of a central angle is 3 x + 18, and the measure of its arc is 147°. Which equation can you use to find the value of x ?
A) 2(3 x + 18) = 147°
B) 3 x + 18 = 2(147°)
C) 3 x + 18 = 147°
Answer:
C
Step-by-step explanation:
The central angle is equal to the measure of the arc that subtends it, thus
3x + 18 = 147 → C
Answer: C.) 3x + 18=147

For acute triangle XYZ below, can you find the tangent ratio of angle r°?
Answer:
Tan r = z/y
Step-by-step explanation:
Tangent = opposite / adjacent
Line XY, which is z, is opposite of angle r.
Line XZ, which is y, is adjacent to angle r.
The equation would be Tan r = z/y.
Answer: No, you can't find the tangent ratio of angle rº because the tangent ratio applies to any right triangle, and it applies to right triangles ONLY.
The sum of two positive integers is 40. When the smaller integer is subtracted from twice the larger, the result is 41. Find the two integers.
Answer:
13 and 27
Step-by-step explanation:
x+y=40
x- smaller
2y-x=41
x=2y-41
Now to plug it into our first equation:
3y-41=40
3y=81
y=27
x=13
Find the 4th term of the expansion of (a - sqrt(2)) ^ 8
Answer:
Applying the binomial theorem
[tex]{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}[/tex]
Here we have x = -[tex]\sqrt{2}[/tex], n = 8,
=> 4th term (k = 3) would be:
[tex]{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}[/tex]

The sum of two consecutive integers is 77. Find the integers.
Answer:
38 and 39
Step-by-step explanation:
Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:
x+(x+1)=77
2x+1=77
2x=76
x=38
x+1=39
Hope this helps!
Answer:I believe it is 39 and 38
Step-by-step explanation:
x + (x+1) = 77
2x = 76
x = 38 (1st number)
x+1 = 39 (2nd number)

What is the probability that the first lands on a 6 and the second lands on a oddnumber? Write your answer in simplified fraction form.
Answer:
1/12
Step-by-step explanation:
1/6 times 1/2 is 1/12
1/6 because if the first number is 6 then it is 1/6 since there are only 6 of them
1/2 because there are 3 odd numbers and 3/6 is simplify to 1/2
Answer:
1 1/2
Step-by-step explanation:
1/6*1/2
I DESPERATELY NEED YOUR HELP!! A cat gets stuck on the roof. If the latter is 12 feet long and must be placed 7 feet away from the building. How high can the ladder reach up the building to save the cat
Answer:
84
Step-by-step explanation:
Answer:
your answer is 9.7 feet
Step-by-step explanation:
you apply Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex] since you are looking for height you can subsitute x for a or b and since 12 is the largest number this will be your c which is your hypotneuse and 7 will be subsituted as a or b depending on what letter you used as your x value [tex]7^{2} +b^{2} =`12^{2}[/tex] is equal too 49 +b^2 =144 you then subtract 49 on both sides to isolate your x (b) and this gets you 95 and then you find the square root of 95 which is 9.7
Triangle ABC is the pre-image and Triangle ADE is the image. What transformation took place?
a. Reflection
b. Translation
c. Dilation
d. Rotation
Answer:
translation...........
Answer:
Dilation
Step-by-step explanation:
A dilation is a type of transformation that changes the size of the image. The scale factor measures how much larger or smaller the image is.
In this example, ΔABC is dilated as seen in the picture because it the picture itself got bigger.
The image, ΔADE is now a dilated version of the pre-image ΔABC

Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm
Which equation represents the line that passes through the points (-4, 10) and (-8, 9)?
(5ab-4a-8) - (9ab-5)
Answer:
Step-by-step explanation:
-4a-4ab-3
Answer:
-4ab+-4a+-3
Step-by-step explanation:
(5ab-4a-8)-(9ab-5)
distribute the negative sign
=5ab-4a-8+-1(9ab)+(-1)(-5)
=5ab+-4a+-8+-9ab+5
combine like terms
=(5ab+-9ab)+(-4a)+(-8+5)
=-4ab+-4a+-3

Answer:
4a ) Difference ⇒ $ 63.24,
4b ) 4 children
Step-by-step explanation:
4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;
y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,
y = 42.16 + 85.15 ⇒ Combine like terms,
y = 127.31
If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;
y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,
y = 105.4 + 85.15 ⇒ Combine like terms,
y = 190.55
Difference; 190.55 - 127.31 = 63.24,
Solution; Difference ⇒ $ 63.24
4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;
169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,
21.08x = 84.32 ⇒ Divide either side 21.08,
x = 4 children
Solution; 4 children
