Step-by-step explanation:

The volume of a rectangular prism is shown below:

We are given the an area of  

173.6

cm

and a height of  

9

cm

.

We also know that the formula for area is  

l

w

, meaning we can substitute the area for  

l

w

in the volume formula.

Now let's plug in what we know into the formula and solve for the volume:

Answer: $16.80

Step-by-step explanation:

The disinfecting wipes cost $12 for the store to buy one.

They then add a 40% mark up.

Find out what 40% of $12 is:

= 40% * 12

= $4.80

Add the markup to the cost to find the selling price:

= 12 + 4.80

= $16.80

Answer:

Step-by-step explanation:

Rewrite log7(49)=x log 7 ( 49 ) = x in exponential form using the definition of a logarithm. If x and b are positive real numbers and b does not equal 1 , then logb(x)=y log b ( x ) = y is equivalent to by=x b y = x .

Answer:

  A

Step-by-step explanation:

If the price of a hot dog is x, then the price of two hot dogs is 2x, and the price of 3 of them is 3x.

If the price of a drink is y, then the price of 2 drinks is 2y.

So, we have the price of 2 hotdogs and 2 drinks is 4.75.

  2x + 2y = 4.75

And the price of 3 hot dogs and 1 drink is 7.75.

  3x + y = 7.75

This pair of equations matches those in choice A.

_____

Comment on the question

We know right away that something is screwy here, because the cost of two hotdogs and 2 drinks should be an even number. 4.75 is not an even number. If we solve this set of equations, we find the cost of a drink is negative—not something you're likely to see in the real world.

So, this is an exercise in writing equations. It has nothing to do with finding real prices.

Answer:

Age of son = 6 years

Age of man = 5×6 = 30 years

Step-by-step explanation:

GIVEN :-

TO FIND :-

SOLUTION :-

Let the present age of son be 'x'.

⇒ Present age of man = 5x

4 years ago ,

Age of son = (Present age of son) - 4 = x - 4

Age of man = (Present age of man) - 4 = 5x - 4

The man was thirteen times as old as his son. So,

[tex]=> 5x - 4 = 13(x - 4)[/tex]

Now , solve the equation.

[tex]=> 5x - 4 = 13x - 52[/tex]

[tex]=> 13x - 5x = 52 - 4[/tex]

[tex]=> 8x = 48[/tex]

[tex]=> \frac{8x}{8} = \frac{48}{8}[/tex]

[tex]=> x = 6[/tex]

CONCLUSION :-

Age of son = 6 years

Age of man = 5×6 = 30 years

Factor by grouping.

(2x + 3)(x − 6)

Answer:

(2x-3) (x+6)

Answer:

Area of equilateral triangle = 81√3 cm²

Step-by-step explanation:

Given:

Perimeter of an equilateral triangle = 54 cm

Find:

Area of equilateral triangle

Computation:

Perimeter of an equilateral triangle = 3 x Side

54 = 3 x Side

Side of equilateral triangle = 54 / 3

Side of equilateral triangle = 18 cm

Area of equilateral triangle = [√3/4]side²

Area of equilateral triangle = [√3/4][18]²

Area of equilateral triangle = [√3/4][324]

Area of equilateral triangle = [√3][81]

Area of equilateral triangle = 81√3 cm²

Answer:

c = 13

Step-by-step explanation:

1. Pythagorean theorem states that c^2 = a^2 + b^2

2. In this case, a = 5, b = 12. Therefore, the equation is:

c^2 = 5^2 + 12^2

3. c^2 = 25+144 = 169

4. square root both sides

5. c = 13, c = -13

6. c = 13 since a length cannot be negative.

7. Final answer: C = 13

Answer:

43

Step-by-step explanation:

Inscribed Angle = 1/2 Intercepted Arc

< MQP = 1/2 ( 86)

< MQP = 43

Answer:

43°

Step-by-step explanation:

The measure of an inscribed angle is half the measure of the arc it subtends.

m<Q = (1/2)m(arc)MP

m<Q = 1/2 * 86°

m<Q = 43°

Firstly this shape is an triangle and a triangle has 3 sides/ angles and all angles sum up to 180 degrees...

E = 90 degrees

This explains that it is an hypotenuse triangle so...

answer:

= 39x39 = 1521

= 89x89 = 7921

= 1521 + 7921 = 9442

= square root of 9442 = 97.169954204 rounded off to 97.2

97.2 degrees!

Answer:

[tex]b(b+7)(b-7)[/tex]

Step-by-step explanation:

Start by factoring a [tex]b[/tex] out:

[tex]b(b^2-49b)[/tex]

For the term [tex]b^2-49b[/tex], we're looking for two numbers that add up to 0 and multiply to be -49:

[tex]7+(-7)=0,\\7\cdot -7=-49\\[/tex]

Two numbers: [tex]7\text{ and }-7[/tex]

Therefore, we have:

[tex]\boxed{b(b+7)(b-7)\checkmark}[/tex]

Answer:

Step-by-step explanation:

The question is incomplete, as the views are not shown.

So, I will answer this question with the attached views of a rectangular prism.

Required

The number of cubes used

For the attached views of the rectangular prism, we will make use of the following representations

Top view [tex]\to[/tex] Width

Front view [tex]\to[/tex] Height

Side view [tex]\to[/tex] Length

So, we have:

[tex]Width = 2 units[/tex]

[tex]Height = 6 units[/tex]

[tex]Length = 1\ unit[/tex]

The number of cubes is calculated by solving for the volume of the prism.

For a rectangular prism, the volume is:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 2 * 6 * 1[/tex]

[tex]Volume = 12[/tex]

This implies that 12 cubes were used to build the solid.

Tyler's wedge is larger

The arc length of Priya's wedge is only 9.42, and Tyler's is 12

Tayler's wedge is larger.

"Arc length is the distance along the part of the circumference of any circle."

S = 2 × π × r

where, r is the radius of the radius of a circle

In this question,

Tyler bought a wedge shaped cheese with arc length 12 cm and radius 8 cm.

Priya bought a wedge that came from a circular cheese block with radius 9 cm and the block was cut into 6 congruent sectors.

The circumference of circular cheese block with radius 9 cm would be,

⇒ s = 2 × π × 9

⇒ s = 18π cm

Since, the block was cut into 6 congruent sectors.

The arc length of each block would be, 18π / 6 = 3π cm

That is, 9.43 cm

Since 12 > 9.43, Tayler's wedge is larger.
