How much water can the large water hold?
Answer:
700 ml
Step-by-step explanation:
If the 15cm bottle holds 500ml of water, you can create the ratio of 15:500, which simplifies to 3:100.
Since the second bottle is 21cm, you find 21:x.
Because you already have 3:100 as given from the first bottle, if you multiply both sides by 7 you get 21:700.
This means the second bottle holds 700ml.
Answer:
700 mi of water
Step-by-step explanation:
We can divide 21 by 15 to how many times greater they are to each other
21÷15=1.4
Since the 15 cm bottle of water can hold 500 mi we multiply 500 • 1.4 = 700mi

What is the equation of the line that passes through the point (3, 2) and has a slope
of 2/3?
Answer:
y=2/3x
Step-by-step explanation:
Hi there!
We want to find the equation of the line that passes through the point (3,2) and has a slope of 2/3
We can write the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
Since we are already given the slope, we can substitute it into the equation as m
y=2/3x+b
Now we need to find b
Since the equation passes through the point (3,2), we can plug its values into the equation to solve for b
Substitute 3 as x and 2 as y into the equation:
2=2/3(3)+b
Multiply
2=2+b
Subtract 2 from both sides
0=b
Substitute 0 as b into the equation
y=2/3x+0
Simplify:
y=2/3x

What is the equation of the given line in standard form? Use integer coefficients.
y=-1.7x + 8.5
A.)17x + 10y = 85
B.)-17x + 10y = 85
C.)-17x + 10y = -85
D.)17x+10y = -85
Answer:
A
Step-by-step explanation:
y = - 1.7x + 8.5 ( add 1.7x to both sides )
1.7x + y = 8.5 ( multiply through by 10 )
17x + 10y = 85 → A

Calculate the height of a tree whose shadow is 20m shorter when the angle of elevation of the sun is 60° than when it's 30°.
Answer:
17.3 m
Step-by-step explanation:
If t is the height of the tree, then the length of the shadow is ...
shadow length = t/tan(α)
where α is the angle of elevation. The difference in shadow lengths is ...
20 m = t/tan(30°) -t/tan(60°) = t(√3 -1/√3)
t = (20 m)/(2/√3) = 10√3 m ≈ 17.3 m
The tree is about 17.3 meters high.

Which postulate or theorem proves that these two triangles are
congruent?
O HL Congruence Theorem
ASA Congruence Postulate
O SAS Congruence Postulate
• AAS Congruence Theorem
Answer:
AAS Congruence Theorem
Step-by-step explanation:
the lines in the angle show similarity. so angle FGJ= angle HJG, similarly, angle F= angle H.GJ is the same as JG so this side of both triangles is congruent. since the order of congruency is the same (triangle GHJ: angle H, angle HJG, then JG; triangle JFG: angle F, angle FGJ, then GJ) and the congruent side length isn't between the congruent angles, it's AAS

The correct answer is C - 7.8 < 7 5/6 < 7.9
Step-by-step explanation:
First, convert 7 5/6 to decimal form --> 7.83.
If you don't know how to convert, think about what 5/6 is equal to and put it in decimal form. Add your decimal to the whole number, and there is your answer.
7.83 is in between 7.8 and 7.9, so it must be the answer.
