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.

Answer:

12x -36yz

Step-by-step explanation:

hope this helps!

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.

Hope everything is clear.

Let me know if you have any questions!

Answer:

C= 25$ + 50$ * h

8 hours 425$

10 hours 525$

Step-by-step explanation:

Answer:

y = 20x + 15

The total cost for 8 hours of work will be $175

Step-by-step explanation:

To find the total cost for 8 hours of work, substitute the x in the equation with 8, and solve. 20 times 8 is 160. 160 + 15 is 175.

Answer:

17.5  

Step-by-step explanation:

180 = 40+ 8x

140 = 8x

17.5  = x

Answer:

17.5 is the correct answer to the question

Step-by-step explanation:

8x+40=180

8x=180-40

8x=140

X=140/8

X=17.5

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

Answer:

Interest = $161.70

Step-by-step explanation:

Formula:

I = Prt

Given:

P = 980

r = 0.055

t = 3

Work:

I = Prt

I = 980(0.055)(3)

I = 53.9(3)

I = 161.7

Answer:

6/10

Step-by-step explanation:

2/10 times 3/1=6/10

hope this helps:) plz mark me brainliest

Answer:

3/5

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

hope this helps:)

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

Answer:

549.5 cm³

Step-by-step explanation:

___________________________________________________________

FORMULA USED IN THE QUESTION :-

Volume of a cylinder whose height is 'h' and radius is 'r' = [tex]\pi \times r^2 \times h[/tex]

___________________________________________________________

According to the question ,

Height of cylinder (h) = 7 cm

Radius of cylinder (r) = 5 cm

Volume of cylinder = [tex]\pi \times 5^2 \times 7 = 3.14 \times 25 \times 7 = 549.5 \: cm^3[/tex]

Answer:

10 hours

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

It will take about 10 hours for Robin to travel 320 miles.

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]

Answer:

Certain

Step-by-step explanation:

The answer is certain because all the numbers on a cube are less than 7. So it's impossible to get a number more than 7, or equal to 7.

Step-by-step explanation:

El 14 es un número compuesto. Es divisible por 1, por 2, por 7 y por 14.

Answer: C

In vertex form a(x - h)2 + k, values of a indicate the horizontal stretch/compression. From there just knowing that values less than 1 stretch the graph, while values greater than 1 compress it. Graphing it out on your own by simply inputting values into x will make this pretty clear.

Answer:

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
