Answer:A

Step-by-step explanation:

Length=L=15cm

Width=w=8cm

Height=h=2cm

Surface area=(2xwxL)+(2xLxh)+(2xhxw)

Surface area=(2x8x15)+(2x15x2)+(2x2x8)

Surface area=240+60+32

Surface area=332 cm^2

Answer:

a. 332 cm²

Step-by-step explanation:

Surface area is the sum of areas of 6 rectangular faces of the box

Opposite faces have equal areas

SA = 2[(15×8) + (15×2) + (8×2)]

= 2[120 + 30+ 16]

= 2(166)

= 332 cm²

How much longer is the hypotenuse of the triangle than its shorter leg? Triangle A B C. Side A C is 6 feet and side C B is 8 fee

REY [17]

Answer:

The answer to your question is 4 ft

Step-by-step explanation:

Data

Side AC = 6 ft

Side CB = 8 ft

hypotenuse = ?

difference = ?

Process

1.- Calculate the hypotenuse using the Pythagorean theorem

c = hypotenuse

a = short leg

b = long leg

c² = a² + b²

-Substitution

c² = 6² + 8²

-Simplification

c² = 36 + 64

c² = 100

-Result

c = 10 ft

2.- Calculate the difference between the hypotenuse and the shorter leg.

difference = 10 - 6

= 4 ft

Describe the value of the 9 in 926,415 use at least 2 terms from the word list in your explanation

Sedbober [7]

Answer:

The value of 9 in 926,415 is nine hundred thousands

Step-by-step explanation:

* Lets explain how to write a number in the expand form

- Expand form is a way of writing numbers to see the math value

of individual digits

- Ex: the expand form of 23,456 is 20,000 + 3,000 + 400 + 50 + 6

- Place value is the value represented by a digit in a number

- Ex: the place value of 5 in 250 is tens

* Lets solve the problem

- The number is 926,415

- The number formed from 6 digits

- The expand form of the number is:

926,415 = 900,000 + 20,000 + 6,000 + 400 + 10 + 5

- Lets write the place value of each digit

# The place value of 5 is ones

# The place value of 1 is tens

# The place value of 4 is hundreds

# The place value of 6 is thousands

# the place value of 2 is ten thousands

# The place value of 9 is hundred thousands

∴ The place value of 9 in the number is hundred thousands

∴ The value of 9 in 926,415 is nine hundred thousands

A bakery asks 75 customers to vote for a new bagel flavor. Onion flavor receives 33 votes. Cheddar flavor receives 42 votes. Use

m_a_m_a [10]

Using proportions, it is found that:

The fraction that shows the proportion of customers who voted for cheddar flavor is $\frac{42}{75}$

56% of customers voted for cheddar flavor.

A proportion is the number of desired outcomes divided by the number of total outcomes.

A percentage is the proportion multiplied by 100%.

In this question, 42 out of 75 customers voted for the cheddar flavor, hence:

$p = \frac{42}{75}$

That is, the fraction that shows the proportion of customers who voted for cheddar flavor is $\frac{42}{75}$

The percentage is:

$\frac{42}{75} \times 100\% = 56\%$

56% of customers voted for cheddar flavor.
