Answer:y =-3x/4+2
Step-by-step explanation:
Slope= -3/4
The line is passing through (0,2).
y-2=(x-0)*-3/4
or
y =-3x/4+2
Fractions, decimals, and percents are all used to describe a
part of something. Which of the 3 types do you think is most
commonly used? Why do you suppose this is true?
Answer:
Step-by-step explanation:
I think that Percents are used very commonly all around us every day. It gives us a better vision in our mind of the quantity than decimals or fractions. We see Percents everywhere. In the shopping mall for discounts, math homework and work. So overall, percents are most commonly used.

Answer:
x = 2
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth, h is height )
Here l = 10x , b = [tex]\frac{7}{4}[/tex] , h = 2 , then
V = 10x × [tex]\frac{7}{4}[/tex] × 2 = 70 , that is
20x × [tex]\frac{7}{4}[/tex] = 70
5x × 7 = 70
35x = 70 ( divide both sides by 35 )
x = 2
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
Since L × W × H = V, we get
[tex]10x*\frac{7}{4}*2=70\\10x*\frac{7}{4}=35\\10x=20\\x=2[/tex]

please help, this is geometry
Answer:
Step-by-step explanation:
r = 3
angle = 50
Formula: Length = (angle/360) * 2 pi * r
Length = (50/360) * 2 * 3.14 * 3
Length = 0.13889 * 2 * 3.14 * 3
Length = 0.13899 * 6 * 3.14
Length = 2.6167

Step-by-step explanation:
You bake a batch of muffins. You freeze 6 muffins and share the rest equally among yourself and 2 friends. Write an expression that can be used to determine the number of muffins,m, each friend gets
Answer:
[tex]m=\displaystyle \frac{t-6}{3}[/tex]
Step-by-step explanation:
Hi there!
Let t equal the total number of muffins.
[tex]t-6[/tex] ⇒ This represents freezing the 6 muffins
[tex]\displaystyle \frac{t-6}{3}[/tex] ⇒ This represents sharing the remaining muffins among 3 people
Therefore, the expression would be [tex]\displaystyle \frac{t-6}{3}[/tex].
If you would like to change this into an equation, it would be [tex]m=\displaystyle \frac{t-6}{3}[/tex], where m is the number of muffins that each person gets.

are these rational numbers
-0.3 is rational. 3.141441444... is not rational.
Step-by-step explanation:
Rational number is either terminal or repeating.
-0.3 is a terminal decimal because it stops. You can write the decimal without "..."
3.141441444... is an irrational number because it is not a terminal decimal (since it has "...") and it is not repeating since the digits on the right side of the decimal are not repeating. They are changing.
3.14141414... would be repeating since "14" is repeated endlessly. However 3.141441444 is "14" then "144" and adding an additional 4 to this pattern with every iteration.

A cylinder has a volume of 100cm and a radius
of 5 cm. What is its height in centimeters? Leave
the answer in terms of .
Answer:
1.27cm
Step-by-step explanation:
Volume(v) =100 cm
Radius(r) =5cm
Height(h) =?
Now,
Volume of cylinder (v) =¶r^2h
100 =22/7*5*5*h
100=78.57h
H=100/78.57
H=1.27cm
Height of cylinder is 1.27cm

Calvin owns a toy store. He can spend at most $200 on restocking cars and dolls. A doll costs $6.50, and a car costs $8.00. Let x represent the number of cars, and let y represent the number of dolls. Identify an inequality for the number of toys he can buy. Then identify the number of dolls Calvin can buy if he buys 10 cars.
8x + 6.50y ≤ 200; no more than 19 dolls
8x + 6.50y ≤ 200; no more than 18 dolls
6.50x + 8y ≤ 200; no more than 19 dolls
6.50x + 8y ≤ 200; no more than 18 dolls
The required inequality expression is 8x + 6.50y ≤ 200
Maximum amount he can spend = $200
Cost of doll, = $6.50
Cost of car = $ 8.00
Mathematically, the maximum amount he can spend on restocking is cars and doll is :
(Cost of cars × number of cars) + (cost of doll × number of dolls) ≤ maximum amount
8x + 6.50y ≤ 200
Hence, the required inequality expression is : 8x + 6.50y ≤ 200

2(6a - 5) + 2(a + 1) =
= 12a - 10 + 2a + 2 =
= 12a + 2a - 10 + 2 = 14a - 8
Answer:
14a-8
Step-by-step explanation:
A perimeter is the sum of the length of each side. So we can find the perimeter by adding: (a+1)+(a+1)+(6a-5)+(6a-5).
Combine like terms to get: 14a+2-10 = 14a-8.
Without knowing what a is, the perimeter is 14a-8.

If the digits A, B and C are added, the sum is the two-digit number AB as shown. What is the value of C?
A
B
+ C
______
AB
Answer:
C=9
Step-by-step explanation:
If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)
AB-(A+B)=C
10-(1+0)=9 or 11-(1+1)=9
therefore C=9
12 only show work pls
Answer:
Step-by-step explanation:
Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that
(x+2)+(x+2)+(2x+3)+(2x+3)=46
Combine like terms to get: 6x+10=46
Subtract 10 from both sides to get: 6x=36
Divide both sides by 6 to get: x=6.
