Answer:

• the rectangular prism has 4 lateral faces.

• the rectangular prism has a surface area of 254 square inches.

Step-by-step explanation:

are you sure you copied the choices right?

because as far as i know the second one, the surface area of the rectangular prism is 254 square inches.

Answer:

The rectangular prism has 4 lateral faces.

Explanation: a rectangular prism has 4 long faces.

The rectangular prism has a surface area of 254 square inches.

Explanation: use the surface area formula: A=2(wl+hl+hw)

W=7

L=9

H=4

A= 2(7*9+4*9+4*7)

A= 2(127)

A= 254 square inches

Hope this helps!

Answer:

102 cm^(2)

The area of the figure is summation of the rectangle and triangle

78+24= 102 cm^{2}

Answer:

3216 cm²

Explanation:

Area of triangular prism = base × height + Length × (perimeter of base)

Here given:

===========================================

Area of the prism = 14 × 24 + 45 × 64 = 3216 cm²

Answer:

Step-by-step explanation:

In order to determine the equation, consider that any exponential growth equation can be written as follow:

[tex]f(t)=A(1+r)^t[/tex]

where,

f(t): amount of bacteria after t hours

A: initial amount of bacteria  = 3

r: growth rate in decimal form = 0.15  (15%)

t: time in hours

By replacing the previous values into the expression for f(t) you get;

[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]

Hence, the answer is f(t) = 3(1.15)^t

Now, replace t = 13 to determine the amount of bacteria after 13 hours:

[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]

Hence, after 13 hours there are approximately 18 bacteria

Answer:

A = 54 units²

Step-by-step explanation:

Area of triangle

[tex]A = \frac{1}{2} \times \text{base} \times \text{perpendicular height}[/tex]

You can read the lengths of the base and the height from the graph. Base is 12 units and height is 9 units. (Count the squares. Or 12 = 13 - 1 and 9 = 14 - 5)

[tex]A = \frac{1}{2} \times 12 \times 9\\A = 54 \text{ units}^2[/tex]

Answer:

6x+3

Step-by-step explanation:

(x+4)+(3x-2)+(2x+1)

=x+4+3x-2+2x+1

=x+4+3x-2+2x+1 --> Here I'm just bolding the variables. This makes it easier to combine like terms in the next line.

=6x+4-2+1

=6x+3

Answer: 840

Step-by-step explanation: 50% is half. All I did was add 420  two time since 420 is half of what this person has to spend.

Answer:

the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.

0.50 times 420= 210

210 is the correct answer and have a great day.

Answer:

20 feet

Step-by-step explanation:

1. We know from here that A = bh (Area = Base x Height).

We are given:

A = 120 ft^2

h = 6 ft

b = ?

2. Let's rearrange our formula (A = bh) so that we find  what "b" equals."

Our new formula will be: b = A/h (base = Area / height).

3. Let's apply it to the question and do the required math!

b = A/h

b = 120/6

b = 20 ft

Answer:

b = 20 ft

Step-by-step explanation:

The area of a parallelogram is given by:

A = b*h

where,

A: area = 120 ft^2

b: base = ?

h: height = 6 ft

From the equation for A, solve for b, replace the values of A and h and simplify:

b = A/h

b = 120ft^2/6ft

b = 20ft

Hence, the length of the base of the parallelogram is 20 ft

Answer: b or c

Step-by-step explanation: they both appear to be the same answer so i don’t know which one it would be

Answer:

22.

Step 1: Find area of inner square = 4 ft × 12 ft = 48ft2

Step 2: Find area of outer shape =

25 ft +11 ft = 36 cm2

Step 3: Area of shaded region = area of outer shape – area of inner square

= 36 ft2 – 48 ft2

= 12 ft2

Answer:

3 kg of copper,

1.25 kg of nickel,

0.75 kg of zinc.

Step-by-step explanation:

i'm assuming you copied the question wrong and that the right metals are, copper, nickel* and zinc.

here's an explanation~

copper ; 12 x 1/4 = 3 kg

nickel ; 5 x 1/4 = 1.25 kg

zinc ; 3 x 1/4 = 0.75 kg

Answer:

720

Step-by-step explanation:

If order mattered, we would say select the first number (10 choices), then the second (9 choices) then the third (8 choices). So there would be 10 x 9 x 8 = 720 possible choices.

Answer:

there are 720 possible answers

Step-by-step explanation:

(10 choices) on the first, then the second (9 choices) then the third (8 choices). So there would be 10 x 9 x 8 = 720 possible choices.
