Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
Your answer is B.) -7, 7

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

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.

~AH1807Find 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.
Sheldon also picks tomatoes from his garden. He picked 4 4/10 but 1.5 were rotten and had to be thrown away. How many kilograms of tomatoes were not rotten? Write an equation that shows how you reached your answer.
Given:
Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg
Rotten tomatoes = 1.5 kg
To find:
How many kilograms of tomatoes were not rotten?
Solution:
Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg
= [tex]\dfrac{4(10)+4}{10}[/tex] kg
= [tex]\dfrac{40+4}{10}[/tex] kg
= [tex]\dfrac{44}{10}[/tex] kg
= [tex]4.4[/tex] kg
Rotten tomatoes = 1.5 kg
Remaining tomatoes which are not rotten is
Required tomatoes = Tomatoes Sheldon picks - Rotten tomatoes
= [tex]4.4-1.5[/tex]
= [tex]2.9[/tex] kg
Therefore, the tomatoes which were not rotten is 2.9 kg.

Solve for x.
78
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

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.

9514 1404 393
Answer:
see attached
Step-by-step explanation:
This calculator problem can be handled easily by a spreadsheet, which can round to whatever number of digits you desire.
The point is probably to see if you understand that the thousandths place digit will increase by 1 if the ten-thousandths place digit is 5 or more. (That is the case only for problem 2.)
__
Additional comment
When doing this with something that only displays 4 decimal digits, you need to be sure that the 4th digit has not been rounded up to 5. For example, ...
0.00149 rounds to 0.0015 and rounds to 0.001 (not 0.002)
Usually, you would give yourself this assurance by showing the hundred-thousandths place in the calculation if you're intending to round to thousandths.
