find the product of 10.2 and 6.3
Answers
Answer:
10.2*6.3=64.26
Step-by-step explanation:
Solve 102*63, then move the decimal point two numbers from the right:
Since 102*63=6426, then moving the decimal point two numbers from the right will mean 10.2*6.3=64.26
Answer:
64.26
Step-by-step explanation:
This is a simple multiplication
When you 'multiply' or 'times' even a product of a number you add it to itself a number of times, for this problem, 10.2 multiplied by 6.3 is the same as saying 10.2 + 10.2 + 10.2 = 64.26. Multiplication is therefore a quicker way of adding the same number many times, for example, 10.2 × 6.3 = 64.26. Therefore, the product of 10.2 and 6.3 is 64.26.

Step-by-step explanation:
alrighty, so this is a standard rate and multiplication problem. How do we know? Well, because there's a steady rate of 2/10 per day, and for 3 days so:
2/10 x 3 = 6/10
6/10 can be simplified:
6/10 ÷ 2 = 3/5
So Daniel eats 3/5 yogurt over the course of 3 days

Volunteers at a food pantry pack boxes of soup into crates. How many boxes of soup will fill each crate? Show your work.
Answers
Answer:
54 boxes
Step-by-step explanation:
Dimension of crate = 12 in by 18 in by 12 in
Volume of crate = (12 * 18 * 12) = 2592 in³
Dimension of box = 4 in by 2 in by 6 in
Volume of box = (4 * 2 * 6) = 48 in³
Number of boxes of soup that will fill each crate :
Volume of crate / volume of box
2592 in³ / 48 in³
= 54 boxes

Hello!
In order to simplify this expression, all we have to do is multiply 3 times the terms inside the parentheses:
3(4x-12yz)
12x-36yz
That's the final answer, because there are no like terms here, so we cannot simplify this expression any further.

Find the volume of the figure.
Answers
Answer:
90 m³Step-by-step explanation:
Volume of the prism is the product of the base area and the height
Base area is:
A = 1/2*10*3.6 = 18 m²Volume is:
V = 18*5 = 90 m³Answer:
Required Answer :-The base is representing a trapezium.
So,
Area = ½ × 10 × 3.6
Area = 5 × 3.6
Area = 18 m²
Now,
Volume = 5 × Area
Volume = 5 × 18
Volume = 90 m²

An electrician needs to know that the relationship between amps, volts, and resistance is
expressed in the formula V = IR where V is volts, I is amps, and R is ohms. How large a
resistance is needed to produce 8 amps from 184 volts?
Answers
Answer:
R = 23 ohms
Step-by-step explanation:
Start with V = I*R. Solve for R: R = V/I
Here I = 8 amps and V = 184 volts, and so
R = (184 volts) / (8 amps) = 23 ohms
The point (-3, 2) lines on a circle whose equation is (x + 3)2 + ( + 1)2 = r2. Which of
the following must be the radius of the circle?
Answers
Answer:
3 units
Step-by-step explanation:
Equation of the circle is:
[tex] (x+3)^2 +(y+1)^2=r^2 [/tex]
[tex] \therefore [x-(-3)] ^2 +[(y-(-1)] ^2=r^2 [/tex]
Equating it with
[tex] (x-h)^2 +(y-k)^2=r^2 [/tex]
We find: h = - 3 & k = - 1
Center of the circle (C) = (-3, - 1)
Since, the point (-3, 2) lies on the circle, therefore radius of the circle wii be equal to the distance between the center of the circle (-3, - 1) and the point (-3, 2) which is on the circle.
Therefore,
[tex] r = \sqrt{[-3-(-3)]^2 +[2-(-1)]^2} [/tex]
[tex] r = \sqrt{[-3+3]^2 +[2+1]^2} [/tex]
[tex] r = \sqrt{[0]^2 +[3]^2} [/tex]
[tex] r = \sqrt{0 +9} [/tex]
[tex] r = \sqrt{9} [/tex]
[tex] r = 3\: units [/tex]

Step-by-step explanation:
320 = 30x + 20
300 = 30x
x = 10
Answer:
10 hours
Step-by-step explanation:
We already have the equation, which is y = 30x + 20. Simply substitute 320 for y, and solve for x.
320 = 30x + 20
First, subtract 20 from both sides.
320 - 20 = 30x
300 = 30x
Now divide both sides by 30.
300/30 = x
10 = x

y = -2x + 3
Step-by-step explanation:
Let's just put the three points together.
(-1, 5) (-4, 11) (-7, 17)
First, let's find the slope with y2 - y1/x2 - x1
Plug in using (-1, 5) and (-4, 11)
11 - 5/-4 + 1 = 6/-3 (simplify)
-2 is the slope
Now plug in (-7, 17) in the equation to get b or the y-intercept)
y = mx + b
17 = -2(-7) + b
17 = 14 + b (subtract 14 on both sides)
3 = b
y = -2x + 3

A truck requires 35 liters of petrol to travel a distance of
450km.Find
The amount that the truck owner has to pay to travel distance of
1050 km if a liter of petrol costs $2.95.
Answers
Answer:
$240.92
Step-by-step explanation:
From the question,
The distance traveled by the truck is directly proportional to the amount of petrol used.
I.e,
d ∝ v............... Equation 1
d = kv
d/v = k
d₁/v₁ = d₂/v₂............. Equation 2
Where d₁ and d₂ are initial and final distance respectively, v₁ and v₂ are initial and final amount of petrol used respectively.
Given: d₁ = 450 km, d₂ = 1050 km, v₁ = 35 liters
Substitute into equation 2 and solve for v₂
450/35 = 1050/v₂
v₂ = (1050×35)/450
v₂ = 36750/450
v₂ = 81.67 Liters.
If a liter of petrol cost $2.95,
Then,
81.67 liters will cost (81.67×$2.95) = $240.92
