Can I get help on 1,2 and 5?
Answer:
Question 1: [tex]x=4[/tex]
Question 2: [tex]x= \pm7[/tex]
Question 5: The dimensions of one face of the container are 6 by 6 inches.
Step-by-step explanation:
Hi there!
Question 1
[tex]x^3=64[/tex]
Rewrite 64 as a power of 3:
[tex]x^3=4^3[/tex]
(We could find that 4³ = 64 through trial and error)
This above equation makes it true that x=4. If aⁿ = bⁿ, then a=b:
[tex]x=4[/tex]
Question 2
[tex]x^2=49[/tex]
Rewrite 49 as a power of 2:
[tex]x^2=7^2[/tex]
Again, we could have found this through trial and error, or by looking at our multiplication tables.
[tex]x=7[/tex]
However, remember that positive and negative numbers will all square to be a positive number. So, therefore, x can be -7 OR 7 (since both, when squared, equal 49):
[tex]x= \pm7[/tex]
Question 5
Let x be equal to the length of one edge of the cube.
Volume of a cube formula: [tex]V=x^3[/tex]
Plug in the given information, when V is the volume:
[tex]216=x^3[/tex]
Rewrite 216 as a power of 3:
[tex]6^3=x^3[/tex]
^ We could have found this through trial and error.
[tex]x=6[/tex]
Therefore, the dimensions of one face of the container are 6 by 6 inches.
I hope this helps!

0.8% of 150 is what numbers and how do you write the equation with a variable in it.
Answer:
1.2
Step-by-step explanation:
1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: [tex]\frac{0.8}{100} * 150 = x[/tex]
2. Now, let's solve for x!
[tex]\frac{0.8}{100} * 150 = (0.008)(150)[/tex] [tex](0.008)(150) = \frac{6}{5}[/tex] [tex]\frac{6}{5} = 1\frac{1}{5}[/tex] [tex]1\frac{1}{5} = 1.2[/tex] [tex]1.2[/tex]Therefore, 0.8% of 150 is 1.2!

What is seven divided by 2?
Help I’ll mark as brainliest pls!!!!!
Answer:
B: Distributive property
Step-by-step explanation:
It is distributive because Robert distributed 3 to x and 2 to make the equation 3x+6=21.
expand and simplify
3-2(k-2)-7(2k-3)
Answer:
- 16k + 28
Step-by-step explanation:
3 - 2(k - 2) - 7(2k - 3) ← distribute parenthesis
= 3 - 2k + 4 - 14k + 21 ← collect like terms
= - 16k + 28
Answer:28−16k
Step-by-step explanation:
3−2(k−2)−7(2k−3)
Use the distributive property to multiply −2 by k−2.
3−2k+4−7(2k−3)
Add 3 and 4 to get 7.
7−2k−7(2k−3)
Use the distributive property to multiply −7 by 2k−3.
7−2k−14k+21
Combine −2k and −14k to get −16k.
7−16k+21
Add 7 and 21 to get 28.
28−16k

[−427⋅(−18)]⋅(−389)⋅(−1)
What is the product?
Answer:
300/1 or 300
Step-by-step explanation:
I took the quiz
The product of the given numbers is 29,89,854.
The given expression is [(−427⋅(−18))⋅((−389)⋅(−1))].
What is product of integers?Integers are the set of whole numbers and their opposites. When you multiply integers, the numbers that you are multiplying are called factors. Your answer after multiplying is called a product.
Product of negative and negative integers is positive.
Now,
(−427⋅(−18)) = 7686
((−389)⋅(−1)) = 389
7686 × 389 = 29,89,854
Therefore, the product of the given numbers is 29,89,854.

If Jose’s house is at -6,8 Tyrell’s house is at 6,8 the football field is at 6,-5 and Jose went to Tyrell’s house then to the football field how far did Jose travel to football practice
Answer:
25 = units Jose travelled
Jh to Th = x moves 12 across
and y moves 0 is constant (up/down or constant)
Th to FF = x moves 0 stays constant and y moves 13 left
12 + 13 = 25
The purpose of this exercise is concerning parabolas = curve equations
x has two points x = -6 and x = 6
y has two points y = -5 and y = 8
however we cant plot this as ANSWER without using all the coordinates
y has one answer unit at 13 and not shown in an equation if it was the y intercept or curve mid point it would be a straight line and not a curve at 13 we can therefore set y to zero 0 as mid point curve when drawing the curve.
Then to find the each unit change we could prove with straight line upon the parabola by first using the straight line equation formula y-y1 = m(x+x1)
Straight line equation
Plug in Jose's coordinates given in the question.
Therefore y - - 6 = 6 (x + 8 ) = y+6 = 6x + 46 multiply out
= y+6 = 6x + 46 -6 cancel out with -6
= y = 6x+40
the answer therefore becomes y=6x+40
Plug in the same for Tyrell coordinates given in the question.
y - 6 = -6 (x + 8 ) = y-6 = -6x + 46 multiply out
= y-6 = -6x - 46 + 6 cancel out with +6
= y = -6x+52
and is a decrease of 6 i various ways.
Plug in for Football field coordinates given in the question.
y-6 = -6(x -5)
= y -6 = -6x +30
= y = -6x + 30+6
= y = -6x + 36
Shows constant 6 and -6 for m the slope and 46-36 = 10 decrease each side from 0 being the curve mid point on x line. down into the mid curve |
= 10+10 to represent each side = 20 then +5 = 25
As the shift in the curve makes negative positive and positive negative.
= 25 units

Help please! I need this done soon
Answer:
y = 3
Step-by-step explanation:
It has to be parallel to the x axis
the coordinates to the point is (6,3)
so to be parallel to x-axis y must always be 3 in this question
so y = 3 is the answer
