God I love Triangles
1: b=36 units
2: C.
1st Explanation:
Given the triangle's sides are to scale, you can take the larger one and divide a side value by it's scaled version to find the rate of change.
In this instance, i took 45/10 and got 4.5, I checked with the other side and found 27/6 also was equivalent to 4.5. This meant the scale from Triangle 1 to Triangle 2 was upscaled by a multiple of 4.5 ...
I took the non-scaled side, and used the common multiple that is present on the other sides, and I found 8x4.5=36.
So, side b, the un-labeled, target side on Triangle 2, equals 36 units. (never forget the units when written, remember this for your future.)
2nd Explanation:
The word problem presents an estimated guess that we are to evaluate it's accuracy of.
I started by reading Laamars, prediction, and checked for any obvious answers. I did not find one, so I moved on to do the math to the estimated penny, by doing:
-Lamar has 1 Full Jar worth $51.45
Value: (51.45)
-Lamar has two identical (same, nearly) jars
Value: (2x51.45)
-Lamar has a 3/4 full jar. So, I converted 3 divided by 4 to .75,
Value: (.75x51.45)
-Lamar has a 1/2 full jar. So, I used one half of 51.45 with the equation: Value: (51.45/2 OR .5x51.45)
So, gathered the values and got the sum of:
Estimated Value = 51.45+(51.45x2)+(.75x51.45)+(.5x51.45) = $218.66
With this in mind, we know Lamar OVERESTIMATED, so we can eliminate answer choices A and B. When you read D, it is already known that the exact value may not be $51.45, so, by process of elimination, I concluded that Lamar most likely overestimated becuase "He has Just over 4 containers, and 4x50=200"
3+.75+.5=4.25, so the statement "just over 4" is true.
Hope this Helped!

Answer:
(b) y = 4x +15; y = 10x -2
Step-by-step explanation:
It is often sufficient to check for reasonableness in the offered answers. That is the case here.
__
The offered answer choices differ in the combinations of slope. The offered slopes (x-coefficients) are 4 or 1/4, 10 or 1/10, so it is sufficient to determine if the slope is greater than 1 in each case.
The slope is the ratio of the change in y to the change in x. It will be greater than 1 if y changes by a larger number than x does.
1st Tablex-values in this table change by 4-2 = 2. y-values change by 31 -23 = 8, which is more than 2. The slope is greater than 1 for the first equation. (It is 8/2 = 4.)
2nd TableThe first two x-values in this table differ by 0-(-1) = 1. The first two y-values differ by -2-(-12) = 10, which is more than 1. The slope is also greater than 1 for the second equation. (It is 10/1 = 10.)

a) 1/14, 1/10 . . . incorrect

4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
Answer:
54cm^2
Step-by-step explanation:
You need to calculate area of the given figure. To solve this there are two figures together, triangle and rectangle.
first find area of rectangle given length = 8 cm and breadth = 4cm
therefore area of rectangle = l * b = 8 * 4 = 32 cm^2
To find area of triangle:
The triangle itself is divided into two right angled triangle.
Now base of one right angled triangle will be 4/2 = 2cm
Area of rt. angled trangle = 1/2 * b*h = 1/2 * 2 * 11 = 11cm^2
Therefore area of whole triangle = 11*2 = 22cm^2 (since there are two rt.angled triangle)
Total area of given figure = 32 + 22 = 54 cm^2

Use the formula for surface area of a cone:
SA = π[tex]r^{2}[/tex] · πrs
'π' stands for the pi(22/7 or 3.14) and 'r' stands for the radius which is being squared. ← This will represent the area of the base of this cone.
'π' stands for the pi(22/7 or 3.14), 'r' stands for the radius, and 's' will stand for the slant height of this cone. ← This will represent the area of the lateral surface of this cone.
What we know;
Slant height = 8 cmRadius = 3 cmCorrect me if i'm wrong with these measurements.
Now plug in what you know into the formula:-
SA = π[tex]r^{2}[/tex] · πrs
SA = 3.14(3^2) · 3.14(3) · 8
Quick note: The ' ^ ' symbol stands for a power symbol, meaning that any base is raised to the power of any exponent.
Solve!
SA = 3.14(9) · 3.14(3) · 8
SA = 28.26 · 9.42 · 8
SA = (28.26 · 9.42) · 8
SA = 266.2092 · 8
SA = 2,129.6736, and rounded to the nearest whole is 2,130.
The surface area of this cone is, 2,130 square centimetres.

for the first values, the number of tickets is 5 and the cost is $40. Effectively, one ticket cost $8 (40/5). So, cou can plug this value in to the x values and check if it matches with the y- values. For sample, 10 tickets 10x8= $80, which matches the table. All these values work.
Answer:
The relationship below is proportional.
Step-by-step explanation:
As we can see to get from 5 tickets to $40 you multiply by 8.
As we can see to get from 10 tickets to $80 you multiply by 8.
As we can see to get from 15 tickets to $120 you multiply by 8.
As we can see to get from 20 tickets to $160 you multiply by 8.
So to make this into an equation we get y=8x
So the relationship is proportional.

Answers
Answer:
22
Step-by-step explanation:
You can just use the previous terms to derive the 4th term.
3rd term: 4(2) + 2 = 10
4th term: 10(2) + 2 = 22
The 4th number in the pattern is 22 .
What is a pattern?
A pattern is a repeated arrangement of numbers, shapes, colors and so on. The Pattern can be related to any type of event or object. If the set of numbers are related to each other in a specific rule, then the rule or manner is called a pattern. Sometimes, patterns are also known as a sequence.
According to the question
Mrs. Johnson asked to form a number pattern using these rules.
rule1: Use the number 1 as the first term.
rule2:To find any other term, double the previous term and add 2
and The first two numbers in the pattern are 1 and 4
therefore ,
First term : 1
Second term : 4 (1*2+2)
Third term : 10 (4*2+2)
Fourth term : 22 (10*2+2)
Hence, the 4th number in the pattern is 22 .

Which of the following is closest to the diagonal length between A and B?
Answers
use the pythagorean theorem to solve this (a2+b2 = c2)
imagine the line as the hypotenuse of a triangle. we already have a2, which is 12, but we don’t have b2 or c2. c2 is the diagonal
to find b2, apply the pythagorean theorem to the 8in and 6in
8^2 + 6^2 = c^2
reducing this makes it 64+36=c^2
add the left side together to get 100=c^2
square root both sides to get 10=c
now we know that the bottom of the “triangle” is 10
now, to find the length of the line, apply the 12 in and 10in we just found into the pythagorean theorem.
12^2+10^2=c^2
reduce it to get 144+100=c^2
add to get 244=c^2
square root both sides to get 15.62=c
the length of the diagonal between A and B should be around 15.62

write an expression to represent a number squared, added to 5
Answers
Answer: x^2+5
Step-by-step explanation:
x is the unknown variable which is representing the number squared and then you add 5 to complete expresssion.
Answer:
x² + 5
Step-by-step explanation:
Given statement:
"number squared, added to 5"We know the following:
1. "number squared" ⇒ A number multiplied to the same number.
Let the number be known as "x". Then;
[tex]\implies x \times x[/tex]
[tex]\implies \underline{x^{2}}[/tex]
2. "added to 5" ⇒ Addition between number, squared and 5.
Let the number be known as "x". Then;
[tex]\implies (x)^{2} + 5[/tex] [tex](\text{number, squared} \implies x^{2} )[/tex]
[tex]\implies \boxed{x^{2} + 5}[/tex]
Therefore, the expression that represents the statement is x² + 5.

12x - 14y cubic yards
Step-by-step explanation:
a keyword in this is... difference
it also asks you to compare the first truck to the second truck not the second to the first
x = the amount of mulch the first truck can deliver
y = the amount of mulch the second truck can deliver
the first truck takes 12 trips so 12 trips multiplied by x (the amount of mulch the first truck can deliver) is 12x because it doesn't give us x
the second truck takes 14 trips so 14 trips multiplied by y (the amount of mulch the second truck can deliver) is 14y because it doesn't give us y
The question asks for the difference between the total number of cubic yards that the first truck carries through their 12 trips and the total number of cubic yards that the second truck carries through their 14 trips.
This gives us, 12x - 14y cubic yards
