Answer:
the large box weight is 6.50 kg and the small box weight is 13 kg
Step-by-step explanation:
The calculation of each type of box weight is shown below:
Let assume the large box be x
And, the small box be y
Therefore
3x + 8y = 91.......(i)
5x + 2y = 78.......(ii)
Multiply by 5 in equation 1 and by 3 in equation 2
15x + 40y = 455
15x + 6y = 234
Now deduct the last equation from the above one
34y = 221
y = 6.5 kg
For x, it is
3x + 8(6.5) = 91
3x + 52 = 91
3x = 91 - 52
3x = 39
x = 13 kg
Hence, the large box weight is 6.50 kg and the small box weight is 13 kg

Answer:
x=7
Step-by-step explanation:
You know that the 17x+11 and 19x-3 are equal because they are corresponding angles. Then, you would solve it like an algebraic equation:
17x+11 = 19x-3
Move all the like terms onto one side.
14=2x
It would be easier to look at if moved the x onto the left so it would look like this:
2x = 14.
Then divide by 2 and your answer should be 7.
Find the equation of the straight line passing through the point (0,1) which is perpendicular to the line y= -2x + 2
Answer:
y = 1/2x + 1
In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.
-2 ⇒ 1/2
Next, we need to substitute the information given into the point-slope formula.
The point-slope formula is:
y - y₁ = m(x - x₁)
y - 1 = 1/2(x - 0)
y - 1 = 1/2x
y = 1/2x + 1
Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.

What is the slope of a line with rise and run of 4?
Answer:
1
Step-by-step explanation:
slope is equal to "rise over run"
or = rise / run.
if you mean by
a rise and a run of 4;
rise = 4 & run = 4,
then the slope is 4 / 4 = 1.

Work out the surface area of this cylinder.
8 cm
16.8 cm
please give me the working out aswell not just a number
Step-by-step explanation:
First, you'd get the area of the circle, then multiply it by two (there's two ends to a cylinder)
so (pi)(R^2)
If 8 is the diameter, then 4 is the radius (r=1/2d)
3.14{pi}*16{4 squared}+=50.27
(50.27*2)= 100.54
Now, we need to find the area of the side of the cylinder. We have the given height of 16.8, and now we need to find the length. In order to do that, we must find the perimeter/diameter of the circle with the formula of Pi*Diameter.
if the diameter of the circle is 8, then 3.14*8=25.12.
25.12*16.8=422.016
now we need to add the area of the circles to get total surface area.
100.54+422.016= 522.556cm^2
I hope this helps!
The surface area of the given cylinder is 522.496 cm².
What is Cylinder?A cylinder is a three dimensional figure which is formed by two parallel circular bases joined by a curved surface.
Center of the two bases is joined by a line called the axis of the cylinder.
Total surface area of cylinder can be found by the total of area of circular bases and the area of curved surface.
Total surface area = Area of Circular bases + Area of curved surface
= 2π r² + 2π r h
where r is the radius of the circular base and h is the height of the cylinder. π is the pi constant with value 3.14
Here, r = 8/2 = 4 cm and h = 16.8 cm
Total surface area = 2πr (r + h)
= 2π × 4 (4 + 16.8)
= 8π × 20.8
= 166.4π
= 166.4 × 3.14
= 522.496
Hence the surface area of the cylinder is 522.496 cm².

Brandy's Candies sells 250 types of candy, and 30% of them are lollipops. How many types of candy are lollipops?
Answer:
75
Step-by-step explanation:
When you have 100% of something, it's all of that one thing, right? So if you were to turn 100% into a decimal, it would be 1. This means you can divide any percentage by 100 to turn it into a decimal. So, 30%=.3. When you multiply something by 2, you get two of that thing, right? And just the same, when you multiply something by half, you get half of that thing. This means you can multiply 250 by .3 to get .3 of it, or, 30%.
250*.3=75

5x-1
15x-3
Answer:
x=8
Step-by-step explanation:
Angle S and R are remote interior angles which means that they would add up to equal angle RQK.
78+5x-1=15x-3
Combine like terms
77+5x=15x-3
Add 3 on both sides
80+5x=15x
Subtract 5x on both sides
80=10x
Divide 10 on both sides
x=8

b) Sanjeev draws a triangle with its sides as 6cm, 8cm and 10cm. Is the
triangle drawn by Sanjeev a right angled triangle? Why?
Answer:
Step-by-step explanation:
Use Pythagorean's theorem. If the sides satisfies Pythagorean theorem, then, they form a right angled triangle.
The longest side is hypotenuse.
Hypotenuse² = base² + altitude²
10² = 6² +8²
100 = 36 + 64
100 = 100
So, 6cm, 8cm, 10 cm makes an right angles triangle.
