Admission to the country fair is $4.50 tickets for the rides are $0.50 each

tester [92]

So first, she has $11.00

Then, she has to pay an entry fee of $4.50

$11.00 - $4.50 = $6.50

If the rides are $0.50 each, divide $6.50 by $0.50

$6.50/$0.50=13

She could purchase 13 tickets for the rides.

How do you divide scientific notation problems like this: 0.00053 ÷ 29?

Shtirlitz [24]

You got to remember
$\frac{x^m}{x^n}=x^{m+n}$

first write them in scienfitic notation
0.00053= $5.3*10^{-4}$
29= $2.9*10^1$

so
$\frac{0.00053}{29}=$
$\frac{(5.3)(10^{-4})}{(2.9)(10^1)}=$
$(\frac{5.3}{2.9})(\frac{10^{-4}}{10^1}=$
$(1.8275862068965517241379310344828)(10^{-4-1})=$
$(1.8275862068965517241379310344828)(10^{-5})=$
$1.8275862068965517241379310344828*10^{-5}$

that's the answer

Need Explanation For This Asap! <3 528 cm2 538 cm2 558 cm2

blsea [12.9K]

Answer:

528 cm²

Step-by-step explanation:

The surface area of this prism comprises:

2 congruent triangles (the bases of the prism)
2 congruent rectangles (rectangle 1 and 2) - since the triangle has 2 sides of equal length
1 rectangle (rectangle 3)

Area of a triangle = 1/2 × base × height

= 1/2 × 16 × 6

= 48 cm²

Area of rectangle 1 / 2 = width × length

= 10 × 12

= 120 cm²

Area of rectangle 3 = width × length

= 16 × 12

= 192 cm²

Total Surface Area = 2 triangles + 2 rectangles + rectangle 3

= (2 × 48) + (2 × 120) + 192

= 96 + 240 + 192

= 528 cm²

a pipe made of metal 1cm thick , has and external radius of 11cm. find the volume of metal used in making 2.4 m long pipe

miv72 [106K]

Answer:

The volume of metal used in making 2.4 m long pipe is 1.58 cm³

Step-by-step explanation:

From the question,

The external radius is 11cm.

Also, the thickness of the pipe is 1cm, then we can determine the internal radius.

Internal radius = External radius - the thickness

Internal radius = 11cm - 1cm

Internal radius = 10cm

Now, to find the volume of metal used in making the long pipe,

The volume of metal used in making the long pipe is the difference between the volume of the external cylinder and the volume of the internal cylinder.

Volume of a cylinder is given by the formula below

$V = \pi r^{2}h$
