Answer:

12566.4 mm²

Step-by-step explanation:

The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.

TSA = Total Surface Area

CSA = Curved Surface Area

TSA of open cylinder = CSA of cylinder + area of base or top

= 2πrh + πr²

= πr(2h + r)

From the above question:

r = 50mm

h = 15mm

Hence,

= π × 50 (2 × 15 + 50)

= π × 50 (30 + 50)

= π × 50(80)

= π × 4000

= 12566.370614mm²

Approximately = 12566.4 mm²

The Surface Area of the petri dish with no lid = 12566.4 mm²

Answer: See explanation

Step-by-step explanation:

Since the complement is the difference between 100% and discount rate. Since the China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. Therefore, the discount rate will be 80% and the complement 20%.

Therefore, the trade discount will be:

= List price × Trade discount rate

= $58.75 × 80%

= $58.75 × 0.8

= $47

Net price = List price - Trade discount

= $58.75 - $47

= $11.75

Answer: -1

Step-by-step explanation: ANSWER : -1

f(x)=3x−1=y

⇒x=3y+1​

∴f−1(y)=3y+1​

⇒f−1(x)=3x+1​

g(x)=5x+6=z

⇒x=5z−6​

g−1(z)=5z−6​

⇒g−1(x)=5x−6​

g−1(f−1(x))=g−1(3x+1​)

=53x+1​−6​

=15x−17​

∴g−1(f−1(2))=

Answer:

12.4 ft  

Step-by-step explanation:

Use the Pythagorean Theorem to find the length of the diagonal of the rectangle:

(4 ft)² + x² = (13 ft)², or 16 + x² = 169 ft²

Then x² = (169 - 16) ft², and x = +√(153 ft²) = 12.4 ft

400 × 2 = $800(24 months=2years)

Answer: 56%

Step-by-step explanation:

Since Janice bought a bag of green and yellow marbles and she received 14 green marbles and 11 yellow marbles, the total number of marbles will be:

= 14 + 11 = 25 marbles

Number of Yellow marbles = 11

Number of Green marbles = 14

Total number of marbles = 25

The percentage of the marbles that were green will be:

= Number of Green marbles / Total marbles × 100

= 14/25 × 100

= 14 × 4

= 56%

Answer:

10/3 pizza

Step-by-step explanation:

step one:

This problem is focused on ratios and fractions

from the problem statement, Martin has 5/6 pizza

Liam has 4 times more of what Martin have

step two:

so we can express what Liam has as

=(5/6)*4 = 20/6or

=5/6+5/6+5/6+5/6= 20/6

= 20/6

Answer:

203.28 miles

Step-by-step explanation:

Given data

charge per day= $45.95

charge per mile= 0.35

The expression for the total is

y= 45.95+0.35x

where x is the number of miles

We want to find the value of x when y= 117.10

substitute

117.10=45.95+0.35x

117.10-45.95=0.35x

71.15=0.35x

x= 71.15/0.35

x=203.28 miles

Answer:

x = 105

Step-by-step explanation:

Let the unknown (missing) number be x.

In Mathematics, quotient simply means division i.e to divide a number by another.

Thus, translating the word problem into an algebraic expression, we have;

[tex] \frac{x}{7} - 5 = 10 [/tex]

To find the value of x, we would simplify the algebraic expression.

[tex] \frac{x}{7} = 10 + 5 [/tex]

[tex] \frac{x}{7} = 15 [/tex]

Cross-multiplying, we have;

[tex] x = 15 * 7 [/tex]

x = 105

Answer:

C. x = 1 3/4

Step-by-step explanation:

7/12 * 9 = 3x/9 * 9

63/12 = 3x -->

(63/12) / 3 = 3x / 3

63/36 = x

x = 7/4 --> 1 3/4

Answer:C AND D

Step-by-step explanation:

Answer:

a. y=2.50x+5

b. The y-intercept of the equation is y=5, or (0,5).

The 5 represents the "b" of the equation where she spent $5

c. The slope of the equation is 2.5 or 2/5.

the slope represents the "m" of the equation where she spent $2.50 per pound on tomatoes

d. y=mx+b

y=2.50(4)+5

y=10+5

y=$15

Step-by-step explanation:

d. y=mx+b

y=2.50(4)+5

y=10+5

y=$15
