Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.

Hey there!

3(x + 19) - 25/5

= 3(15 + 19) - 25/5

= 3(15) + 3(19) - 25/5

= 45 + 57 - 25/5

= 45 + 57 - 5

= 102 - 5

= 97

OR

3(x + 19) - 25/5

= 3(15 + 19) - 25/5
= 3(34) - 25/5

= 102 - 25/5

= 102 - 5

= 97

97 = 97 ☑️

Therefore, your answer is: 97

Good luck on your assignment & enjoy your day!

Answer:

Step-by-step explanation:

In the question we have given an expression that is 3 ( x + 19 ) - 25/5 and value of x is equal to 15 .

And we are asked to find the value expression when value of x is 15 .

Solution : -

[tex] \longmapsto \: 3( x+ 19) - \cancel{\frac{25}{5} }[/tex]

Step 1 : Substituting value of x in given expression and cancelling 25 by 5 :

[tex] \longmapsto \: 3(15 + 19) - 5[/tex]

Step 2 : Solving parenthesis by adding 15 and 19 :

[tex] \longmapsto \: 3(34) - 5[/tex]

Step 3 : By multiplying 3 with 34, we get :

[tex] \longmapsto \: 102 - 5[/tex]

Step 4 : Subtracting 5 from 102 :

[tex] \longmapsto \: \red{ \boxed{ \frak{97}}}[/tex]

Answer:

It is Statistical. Karissa would have to count how many boogers she has in her left nostril.

Step-by-step explanation:

.

The given question is not a statistical question.  So, option (B) is correct. Since this is not related to any other data and there is no variation with the previous data, this is not a statistical question.

The statistical question is a question that can be answered by collecting data and there will be a variation in the data used for calculating.

Given that " How many boogers does Karissa the orge have in her left nostril?"

This question does not need any collection of data. So, this is not a statistical question.

Therefore, option B is correct.

x=6

Step-by-step explanation:

x ÷ 7 ÷10 = 3/35

(Use trial & error - since I knew x<7)

6/7 ÷ 10 = 3/35

Or

3/35 x 10

(then, simplify it to 6/7 or ÷ that by 1/7 to get 6)

Answer:

Total Surface Area

= 384 sq ft

Step-by-step explanation:

To find Total Surface Area, add up the areas of all the sides of the shape. A square based pyramid has five sides, a square bottom and four triangular sides. Luckily all four sides are the same, so just one calculation for these.

Area of square base is given.

A = 144 sq ft

Since the base is a square the length of the side of the square is 12, because 12×12 is 144.

The side of the square base is the base of the triangular side.

Area of a triangle:

A = 1/2•b•h

A = 1/2(12)(10)

A = 60

The area of one triangular face is 60. There are four of these.

A = 4(60)

A = 240

This is the area of all the triangular faces.

Add them all up.

A (TOTAL)

= 144+240

= 384 sq ft

Answer:

44.452

Step-by-step explanation:

Using the Pythagorean theorem you can use:

51^2 = 25^2 + w^2

2601 = 625 +w^2

w^2 = 1976

w = 44.452

Answer:

The width is 44.5in.

Step-by-step explanation:

25^2 + b^2 = 51^2

625 + b^2 =2601

b^2= 2601-625=1976

Square root it (1976)
