1. Astronauts traveling to the International Space Station have to be very careful about
weight (it takes about 9 lbs of rocket fuel to send 1 lb of stuff to the station). Each
astronaut can bring approximately 11 lbs of personal items (mementos and clothes)
with them into space. Each memento weighs about 0.1 lb, and each item of clothing
weighs about 0.5 lbs. If an astronaut wanted to bring 30 items with them, how many
mementos and pieces of clothing would they bring?
Answer:
10 mementos and 20 items of clothing
Step-by-step explanation:
Using the system of linear equations, the astronauts will bring 10 mementos and 20 clothings.
Let :
mementos = mClothing = c m + c = 30 - - - - - - - - - (1)0.1m + 0.5c = 11 - - - - - (2)From (1) :
m = 30 - c - - - - (3)Put m = 30 - c in (2)
0.1(30 - c) + 0.5c = 11
3 - 0.1c + 0.5c = 11
Collect like terms :
0.4c = 11 - 3
0.4c = 8
c = 8/0.4
c = 20
From (3) :
m = 30 - c
m = 30 - 20
m = 10
Therefore, Astronaut will bring 10 mementos and 20 clothings.

5. Which single step will solve the equation 9 = x-3?*
O Multiply both sides of the equation by 3.
O Subtract 3 on each side of the equation
Divide by 3 on each side of the equation
O Add 3 to each side of the equation
Answer:
Add 3 to each side of the equation
Step-by-step explanation:
The problem is 9+ x-3, so to isolate the x we need to remove the -3, and to do that we need to add positive 3 and whatever you do to one side you must do to the other! hope this helps

Describe the nature of the roots for the equation 49x^2-
28x +4 = 0
O one real root
one complex root
O two complex roots
O two real roots
Answer:
Step-by-step explanation:
One real root
The nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
The equation is given as:
[tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex]
To determine the nature of the roots, we make use of determinants.
The determinant (d) of a quadratic equation is calculated
[tex]\mathbf{d = b^2 - 4ac}[/tex]
Where the quadratic equation is:
[tex]\mathbf{ax^2 + bx + c = 0}[/tex]
By comparison, we have:
[tex]\mathbf{a = 49,\ b = -28,\ c = 4}[/tex]
So, we have:
[tex]\mathbf{d = b^2 - 4ac}[/tex]
[tex]\mathbf{d = (-28)^2 - 4 \times 49 \times 4}[/tex]
[tex]\mathbf{d = 784 - 784}[/tex]
[tex]\mathbf{d = 0}[/tex]
When d = 0, then the function has one real root.
Hence, the nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root

Megan has 62 rocks in her rock collection. She wants to put 2 rocks in some cases and 11 rocks in other cases. Select a possible arrangement of rocks. A. Have 4 cases of 2 rocks, and 9 cases of 11 rocks. B. Have 9 cases of 2 rocks, and 4 cases of 11 rocks. C. Have 9 cases of 2 rocks, and 1 case of 11 rocks. D. Have 1 case of 2 rocks, and 4 cases of 11 rocks.
Answer:. B. Have 9 cases of 2 rocks, and 4 cases of 11 rocks
Step-by-step explanation:
Total rocks = 62
A. Have 4 cases of 2 rocks, and 9 cases of 11 rocks
(4 * 2) + (9 * 11) > 62 ( false)
B. Have 9 cases of 2 rocks, and 4 cases of 11 rocks
(9 * 2) + (4 * 11) = 18 + 44 = 62 rocks (true)
C. Have 9 cases of 2 rocks, and 1 case of 11 rocks
(9 * 2). + (1 * 11) < 62 ( false)
D. Have 1 case of 2 rocks, and 4 cases of 11 rocks.
(1 * 2) + (4 * 11) < 62

The equation that describes the line of symmetry in the figure given is:
x = -3.
What is a Line of Symmetry?A line of symmetry is a fictitious line that divides a shape or figure into two equal halves, one of which is a mirror image of the other.
A line of symmetry running along the vertical axis will divide the supplied triangle into two equal halves (x-axis).
Equation of the Vertical axis is expressed as
x = -3.
Thus, the equation that describes the line of symmetry is: x = -3.

Elena has some bottles of water that each holds 17 fluid ounces. Write an equation that relates the number of bottles of water (b) to the total volume of water (w) in fluid ounces.
1) How much water is in 51 bottles?
2) How many bottles does it take to hold 51 fluid ounces of water?
Answer: The equation that relates b to w is 17b=w
1) How much water is in 51 bottles? : 867 fluid ounces
2) How many bottles does it take to hold 51 fluid ounces of water? : 3 bottles
Step-by-step explanation: If you want an explanation, here you go:
For the first question (how much water is in 51 bottles), you use the equation that I wrote, 17b=w. Substitute the b with the amount of bottles, 51, and just solve for the variable, w. You get (17*51=) 867 fluid ounces.
For the second question (how many bottles does it take to hold 51 fluid ounces of water), you simply divide. 51/17=?. ?=3 bottles.
Hope this helps, you can use a calculator to check my work.
