What is the surface area of this triangular pyramid?

Answer:

See Explanation

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.

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

9514 1404 393

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.

40 gold

24 silver

33 Bronze

Step-by-step explanation:

Since all answers have 40 gold medals won we can use this as our default. So 40/5=8 and 8*3 = 24 so the ratio of gold to silver is 40:24. Now to find silver to bronze 24 silver divided by 8=3 and multiplied by 11=33 so the ratios are 40:24:33

Answer:

10 students

Step-by-step explanation:

I've drawn a venn diagram to explain the distribution in this question and attached it.

From the venn diagram, we can see that;

(M) = 60

(S) = 50

(M ∩ S) = 20

Now, to find how many of them failed both subjects, we will use the formula;

100 = (M' ∩ S') + (M) + (S) - (M ∩ S)

Where (M' ∩ S') is number of people that failed both subjects

Plugging in the relevant values we have;

100 = (M' ∩ S') + 60 + 50 - 20

100 = (M' ∩ S') + 90

(M' ∩ S') = 100 - 90

(M' ∩ S') = 10

Answer:

64.62

Step-by-step explanation:

8 3/7 times 7 2/3 is 64.62 (rounded up)

The area of the quilt made by Keiko is 64.61 cubic feet.

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write area -

V = ∫∫F(x, y) dx dy

Given is that Keiko made her mother a quilt. The width of that Keiko is 8 3/7 ft and the length is 7 2/3 ft. It is asked to find the area of the quilt.

We have -

Width of that quilt : 8 3/7 ft  

Length of the quilt : 7 2/3 ft

The area of a quilt is given by -

Area of quilt = Length of quilt x width of quilt

Area of quilt =  8 3/7 x 7 2/3

Area of quilt = 59/7 x 23/3

Area of quilt = 64.61 cubic feet

Therefore, the area of the quilt made by Keiko is 64.61 cubic feet.

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
