1) Hot dogs are sold in packs of 10 and hot dog buns are sold in packs of 8. Tommy wants
to know the least number of packs of hot dogs and buns he needs to buy so that he does not
have any left over.
) Complete the table.
Answer:
10, 20,30, 40, 50
Step-by-step explanation:
You times them all by 10 for example: 1x10=10 2x10=20 3x10= 30 4x10=40 and 5x10=50.
If we buy four packs of hot dogs and five packs of buns then we don't have any left over.
What is Least common multiple?The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.
For example: Take two integers, 2 and 3.
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20….
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 ….
Therefore, 6 is the least common multiple of 2 and 3.
Given:
Packs 1 2 3 4 5
Hot Dogs 10 20 30 40 50
Bun 8 16 24 32 40
Also, LCM(10, 8)
10= 2 x 5
8= 2 x 2 x 2
So, LCM(10, 8)= 2 x 2 x 2 x 5 = 40
Hence, If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

2x - 19
Step-by-step explanation:
Perimeter = sum of sides
First let's simplify each side
We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.
2(x + 5)
Distribute by multiplying x and 5 by 2
2 * x = 2x and 2 * 5 = 10
2x + 10
1/2(4x + 8)
Distribute by multiplying 4x and 8 by 1/2
1/2 * 4x = 2x and 1/2 * 8 = 4
2x + 4
-3(2x + 11)
Distribute by multiplying 2x and 11 by -3
-3 * 2x = -6x
-3 * -33
-6x - 33
Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )
2x + 10 + 2x + 4 - 6x - 33
Combine like terms
2x + 2x - 6x = -2x
10 + 4 - 33 = -19
Perimeter: -2x - 19

Graph the linear equation 5x-4y < 20
Answer: (See attached image file)
Step-by-step explanation:
Start by plotting given key featuresBased on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x (5x = 20)(x = 20/5 = 4) (4, 0) We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5) (0, -5) Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.
Which is an equation of the line containing (1, –3) and (7, 15)?

Write the sum of 7divided by 7x^6+ 4 dividend by 7x^6 in simplest form, if x = 0
Answer:
0
Step-by-step explanation:
The equation if I read this correctly is:
(7 / 7x⁶+4) / 7x⁶
Using x = 0 you would have:
[7 / (7(0)⁶+4)] / 7(0)⁶
(7 / 0 +4) / 0
(7/4) / 0 which is the same as 7/4 x 0 = 0

Does x=5 satisfy the equation 3x + 2 +5x= 95 explain
Answer:
No
Step-by-step explanation:
3x + 2 +5x
if x=5
3(5)+2+5(5)
=15+2+25
=42 which is not equal to 95
No, it doesn't satisfy the equation
Step-by-step explanation:
3x + 2 +5x = 95
Now putting the value of x
3×5 + 2 + 5×5 = 95
15 + 2 + 25 = 95
42 ≠ 95
Hence, x = 5 doesn't satisfy the equation 3x + 2 +5x= 95

The number of termites in a nest in any given month can be represented by the
function f(t) = 4(3)^t where t represents the number of months.
The number of ants in a box can be represented by the function represented by the
table:
Months
0-1-2-3-4
Number 20-45-101-228-513
What is the positive difference in the number of termites and the number of ants in
the fourth year?
im pretty sure the answer is 189
The positive difference in the number of termites and the number of ants in the fourth month will be 189. Option B is correct.
What is the application of subtraction?In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that, the number of termites in a nest in any given month can be represented by the function [tex]\rm f(t) = 4(3)^t[/tex].
For the fourth month,
f(4) = 4(3)⁴
f(4) = 324
From the table, it is observed that the number of ants in four months is 513.
The positive difference in the number of termites and the number of ants in the fourth month is found as,
=513-324
=189
Thus, the positive difference in the number of termites and the number of ants in the fourth will be 189. Option B is correct.

A science class has 5 girls and 3 boys in the seventh grade and 4 girls and 4 boys in the eighth grade. The teacher randomly selects a seventh grader and an
eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Write your answer as a fraction in simplest form.
Answer:
To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.
There are 12 7th-graders and 8 8th-graders. So the total number of ways she can pick is:
12

8
=
96
To get two boys picked, there are 5 boys in the 7th-grade class and 4 in the 8th-grade class, so there are:

=

ways
Which gives us the probability of:

Find the value of x.
Answer:
for this problem we use the sine function
[tex] \sin(x) = \frac{opp}{hyp} \\ \sin(38 ) = \frac{x}{100} [/tex]
multiply both sides of the equation by 100
[tex]100 \sin(38) = \frac{100x}{100} [/tex]
100 cancels on the right hand side of the equation
[tex]100 \sin(38) = x \\ x = 61.566\:ft[/tex]
