Javier bought 1/2 liter of soda for his party. Javier's brother bought a liter of soda and Javier's mom bought 200 milliliters of soda. How many total milliliters did Javier have for his party?
Answer:
1,700 milliliters
Step-by-step explanation:
Convert the liters that Javier and his brother got into milliliters.
In 1 liter, there are 1000 milliliters.
So, Javier's brother bought 1000 milliliters of soda.
And, in 1/2 liter of soda, there are 500 milliliters. So, Javier bought 500 milliliters of soda.
Add these two amounts to how much Javier's mom bought:
500 + 1000 + 200
= 1700
So, for his party, Javier has 1,700 total milliliters of soda.

Answer:
x = 4
Step-by-step explanation:
The parallel lines divide the sides proportionally, so ratios of corresponding sides are the same.
(x +5)/15 = (5x +1)/35
Multiplying by 105, we have ...
7(x +5) = 3(5x +1)
7x +35 = 15x +3 . . . . . eliminate parentheses
32 = 8x . . . . . . . . . subtract 7x+3 from both sides
4 = x . . . . . . . . divide by 8

30 ≥ 5(6n) Choose the correct answer. n ≤ 2 or
n ≤ 1
Answer:
1 ≥ n
Step-by-step explanation:
30 ≥ 5(6n)
Distribute
30 ≥ 30n
Divide each side by 30
30/30 ≥ 30n/30
1 ≥ n
30 >= 5(6n)
Divide both sides. Y 5:
6 >= 6n
Divide both sides by 6:
1 >= n
Rewrite as: n ≤ 1

The perimeter of a rectangle is 32 inches. The length is 1 foot. What is the width of the rectangle in inches? A. 4 inches B. 10 inches C. 15 inches D. 20 inches 12 / 15
Answer:
A. 4 inches
Step-by-step explanation:
Applying,
P = 2(L+W)............. Equation 1
Where P = Perimter of the rectangle, L = Length of the rectangle, W = width of the rectangle.
make W the subject of the equation
W = (P/2)-L............ Equation 2
From the question,
Given: P = 32 inches, L = 1 foot (Convert from Foot to inches), L = 12 inches
Substitute these values into equation 2
W = (32/2)-12
W = 16-12
W = 4 inches.
Hence the right option is A.

which two ratios represent quantities that are proportional help i will mark as brainless
Answer:
A
Step-by-step explanation:
So, lets take all of our ratios, and simplfy them the best we can. Once we do this, we can easily compare and see which ratios are and are not similar.
So lets start with A:
21/28 and 12/16
Lets simplfy each fraction.
The greatest number that goes into the numeraotr and denominator(GCF) of 21/27 is 7. Taking out 7 we get:
3/4
We can do the same with the 12/16. 4 goes into both the numerator and denominator:
3/4
So this would work.
Lets look at the others, and see if any others work as well:
56/64 and 36/48
8 goes into both 56 and 64:
7/8
4 goes into 36 and 48:
9/12
These are clearly different.
Next we have 9/10 and 10/9
We can instantly see that one is bigger than 1, and the other is smaller than 1, so they must be different.
Finally we have 5/7 and 7/14
Again, these are clearly different.
If we give both the same denominator, which can be 14, we get:
10/14 and 7/14
We get 10/14 from 5/7 since we need to multiply both numerator and denominator by 2 so that the 7 becomes 14 in the denominator.
10/14 adn 7/14 are clearly different, so these dont work as well.
Only A, which is 21/28 and 12/16, will work.
Hope this helps!

A)2^4x+2
B)4•16^x
C)2+4^4x
D)2^2 • 4^x (over) 4^-x
E)4^2x+1
Answer:
C) 2+4^4x
Step-by-step explanation:
A) 2^(4x+2) = 2^4x • 2² = 16^x • 4
B) 4 • 16^x = 16^x • 4 (already done)
D) 2^2 • 4^x (over) 4^-x
= 4 • 4^x • 4^x = 16^x • 4
E) 4^(2x+1) = 4^2x • 4¹ = 16^x • 4
Emilio plays basketball. During his last 6 games he made 24 out of 60 free
throw shots. If Emilio will have 25 free throws shots in the next games,
about how many he expects to make?
24 out of 60 is 0.4 which is 40%, so to find out how many he would make in 25 throws you multiply 25 by 0.4 then you would get 10 out of 25.

-4(3 + 4x) - 8(x + 6) = 12
Please show work
Answer:
-3
Step-by-step explanation:
-4(3+4x)-8(x+6)=12
-12-16x-8x-48=12
-12-48-16x-8x=12
-60-24x=12
24x=-60-12
24x=-72
x=-72/24
x=-3
Answer:
x = -3
Step-by-step explanation:
-4(3 + 4x) - 8(x + 6) = 12
-12 - 16x -8x - 48 = 12
-24x - 60 = 12
-24x = 72
x = -3
A triangle has sides with lengths of 8 centimeters, 15 centimeters, and 17 centimeters. Is it a right triangle?
Answer:
Yes it is!
Step-by-step explanation:
If you want to know whether it is, use the pytheoream theory. a2+b2=c2
a is the shortest side, b is the second longest and c is the longest.
In this case, the equation will be:
8 sq + 15 sq = 17 sq
64 + 225 = 289
= It is a right-angled triangle!

Answer:
x = 6.8829
Step-by-step explanation:
[tex]\frac{sin\left(35\right)}{x}=\frac{sin\left(90\right)}{12}[/tex]
Answer:
x ≈ 6.8
Step-by-step explanation:
Label each side of the triangle with "a" (adjacent), "o" (opposite), or "h" (hypotenuse).
Side x is the opposite, side 12 is the hypotenuse, and the other side is the adjacent.
Use SOH-CAH-TOA to find the missing side (Sin, Cos, Tan).
To find x, we need to use SOH or Sin(a)= O/H
Plug in the adjacent angle for a and 12 for h then solve:
Sin(35)=O/12
The calculator approximation of Sin(35) is 0.5735.
0.5735 ≈ O/12
Multiply both sides by 12:
12 * 0.5735 ≈ O/12 * 12
O ≈ 6.882
Round to nearest tenth:
O ≈ 6.8
A woman purchases 10 bananas and 15 oranges. What percentage of fruit purchased was oranges?

ab - 0.5b when a = 1 and b = 5
Answer:
2.5
Step-by-step explanation:
a = 1
b = 5
ab
= 1 x 5
= 5
0.5b
= 0.5 x 5
= 2.5
ab - 0.5b
= 5 - 2.5
= 2.5
Answer:
2.5
Step-by-step explanation:
ab - 0.5b
a = 1 and b = 5
(1)(5) - 0.5(5)
Multiply (1)(5) = 5
5 - 0.5(5)
Multiply -0.5(5) = -2.5
5 - 2.5
Subtract 5 - 2.5 = 2.5
2.5

Write the equation for a line Parallel to this one.
y = 3x + 2
a
y = 3x + 2
y = 3x + 7
ос
y = (1/3)x + 7
Od
y = -(1/3)x + 3
Answer:
actually, a and b are correct, as any line is also parallel to itself (a).
b is probably the truly wanted answer, as this line is on a chart visible as a second line and parallel to the first one.
Step-by-step explanation:
the factor of x is also the slope of the line.
for a line to be parallel to another, both need to have the same slope.
the constant number in the equation is the offset of the line from point (0,0) in y direction.
so, b is a parallel line 4 units above the first line.
If you use squares to approximate area,what do you use to approximate volume?
