Answer:
120
Step-by-step explanation:
Lets take it step by step!
Step 1 : first mutiply -1/2 * -1/3
-1/2 * -1/3 = 1/6
(remember to mutiply fractions we have to mutiply there denominator and numerator together)
Step 2 : then move on and multiply 1/6 * -1/4
1/6 * -1/4 =
-1/24
Step 3 : Next we have to go and multiply -1/24 by -1/5
-1/24 * -1/5 =
1/120
Step 4 : Finally we switch the numerator and denominator to find its reciprocal which is :
120!

Solve the equation by factoring. z2 – 6z – 27 = 0
z = –3 or z = 9
z = –3 or z = –9
z = 3 or z = –9
z = 3 or z = 9
Answer:
The value of z = -3 or z = 9
Step-by-step explanation:
Given equation => z² – 6z – 27 = 0
=> z² - 9z + 3z - 27 = 0
=> z(z -9 ) +3 (z - 9 ) = 0
=> (z + 3) (z - 9)
=> z = -3 or z = 9
Answer:z = –3 or z = 9

A pyramid has a square base that has an area of 144 square feet. If the slant height of each triangular face is 10 in, what is the total surface area of the pyramid?
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
In a 51-inch television, the length of the screen's diagonal is 51 inches. If the screen's height is 25 inches,
what is the width? Round your answer to the nearest tenth of an inch.
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)

this is just a subtraction problem. What you know is that it snowed 5ft yesterday and 2/3ft today. So that means that the amount of more snow yesterday can be calculated with 5 - 2/3ft (this will show how much more snow there was yesterday). The result of this expression would be 4 1/3.

What is the value of the expression 3(x+19)-25/5 if x=15
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

Answer:
Value of expression = 97Step-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 :
