Answer:
85%
Step-by-step explanation:
100% = 20L
so.....10% = 2L
and
5% = 1 L
therefore the missing 3L are equal to 15%
leaving the remainder of the tin 85% filled with petrol

Step-by-step explanation:
Angles in a triangle add up to 180° and angles on a straight line add up to 180° with this information we can solve this problem.
180° - 95° = 85°
Now you have two of the angles, which means all you have to do to find the x is add your two angles up and take them away from 180°.
85° + 60° = 145°
180° - 145° = 35°

Determine whether the triangles are congruent. Explain your reasoning .
SAS (Side, Angle, Side) or ASA (Angle, Side, Angle)
Answer:
Yes, SAS Theorem
Step-by-step explanation:
The triangles are congruent because of SAS Theorem that states that if two triangles have two sides and the angel in between them congruent the triangles are congruent.
JK≅NM (Side) because the sides have the same measure 74in. they are ≅
∡J≅∡M (Angle) because the angles have same measure 37° they are ≅
JL≅PM (Side) because the sides have the same measures 46in. they are ≅
Can someone please give me the answer to this
Answer:
The answer is (4, -6)
Step-by-step explanation:
Point C starts at (2, -5). The triangle moves 2 units right, so 2 + 2 = 4 and 1 unit down, so -5 - 1 = -6

im not really sure how to solve for y here
Answer:
Step-by-step explanation:
Cross multiply. When you have two fractions set equal to each other, you can cross multiply to solve.
5(3y - 8) = 12y and
15y - 40 = 12y and
3y = 40 so
y = 40/3, choice A.

2.A ball is pulled out of a bag on the first pick. Then, it
is replaced in the bag and another ball is picked out . Independent or dependent ?
Answer:
Independent
Step-by-step explanation:
Since the ball is replaces, the same number of balls and type of balls are in the bag. The draw is identical to the first draw so the draws are independent.

use the diagram to find the value of x and y
Answer:
x = 6
y = 15
Step-by-step explanation:
We can find the value for x and y using similarity ratio
8/12 = 10/y cross multiply expressions
8y = 120 divide both sides by 8
y = 15
12/(x+12) = 10/15
180 = 10x + 120 subtract 120 from both sides
60 = 10x divide both sides by 10
6 = x

Answer:
5x -7y = -3
Step-by-step explanation:
The equation of the perpendicular line can be written using the given equation as a starting point. Swap the x- and y-coefficients and negate one of them. In standard form, the x-coefficient must be positive.
Find the new constant by using the x- and y-values of the given point.
-7x -5y = 9 . . . . given equation
-5x -7y = c . . . . equation with coefficients swapped
5x -7y = c . . . . . equation with swapped coefficients, x-coefficient negated
5x -7y = c = 5(-2) -7(-1) = -10 +7 = -3
The equation of the perpendicular line is ...
5x -7y = -3
Do the side lengths 7, 20 and 21 form a right triangle?
==============================================
Work Shown:
a^2+b^2 = c^2
7^2+20^2 = 21^2
49+400 = 441
449 = 441
We end up with a false equation, so the original equation is false for those a,b,c values.
By the pythagorean theorem converse, we do not have a right triangle.
Because a^2+b^2 > c^2, this triangle is acute.
4 1/2 ounces per 3/4 miles
_____ ounces per 1 mile
Answer: 6
Step-by-step explanation:
To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.
[tex]\frac{3}{4}[/tex]×[tex]\frac{4}{3} =1[/tex]
We need to multiply the 4 1/2 ounces by 4/3 too
[tex]4\frac{1}{2}[/tex]×[tex]\frac{4}{3} =6[/tex]
4 1/2 ounces per 3/4 miles
6 ounces per 1 mile
Answer:
6 ouncesStep-by-step explanation:
Let the unknown number be x
[tex]4 \frac{1}{2} \: \: ounces = \frac{3}{4} \: \: miles \\ x = 1 \: \: mile[/tex]
Now simply use cross multiplication to solve it
[tex]4 \frac{1}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} = \frac{3x}{4} \\ [/tex]
Now make x as the Subject
[tex] \frac{9}{2} = \frac{3x}{4} \\ \frac{9 \times 4}{2 \times 3} = x \\ \frac{36}{6} = x \\ 6 = x[/tex]
So the answer is
6 ouncesI need help please!!!

What are the integer solutions to the inequality below?
4x+1<5x≤3(x+2)
Answer:
1<x≤3
Step-by-step explanation:
1. 4x+2y= 6
A.what is the slope-intercept form?
B.What is the slope?
C.What is the y intercept?
Answer:
The slope is -2 and the y intercept is 3
Step-by-step explanation:
4x+2y= 6
Solve for y
Subtract 4x from each side
4x-4x+2y= -4x+6
2y = -4x+6
Divide by 2
2y/2 = -4x/2 +6/2
y = -2x+3
This is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is -2 and the y intercept is 3
