28/z- z/4+1 1/8 when z =4
Answer:
7 1/8 or 7.125
Step-by-step explanation:
first subsitute z for 4
28/4 - 4/4 + 1 1/8
then do 28/4 - 4/4 which is 6,
add that to 1 1/8
and get 7 1/8
Answer:
Step-by-step explanation:
[tex]\frac{28}{z}-\frac{z}{4}+1\frac{1}{8}=\frac{28}{4}-\frac{4}{4}+\frac{9}{8}\\\\=7-1+\frac{9}{8}\\\\=6+\frac{9}{8}\\\\=\frac{6*8}{1*8}+\frac{9}{8}\\\\=\frac{48}{8}+\frac{9}{8}\\\\=\frac{57}{8}\\\\=7\frac{1}{8}[/tex]

The formula for the volume, V. of a pyramid is V = 1/3 Bh, where B is the area of the base of the pyramid and h is the pyramid's height. The base of
the pyramid shown has a length of 9 m and a width of 8 m. The height of the pyramid is 12 m.
What is the volume of the pyramid?
A. 136 m^3
C. 288 m^3
D. 324 m^3
B. 256 m^3
Answer:
C. 288 m^3
Step-by-step explanation:
Step 1: find out B, since we know the length and width for the base, we would need to multiply 9 and 8 to get 72m^2
V= 1/3(72m^2 *12)
Step 2: Simplify
V= 1/3*864m^3
V=288m^3

A six-sided dice is rolled twice. What is the probability that a one is rolled both times?
The probability of rolling a one is 1/6 because there is one side labeled "1" out of 6 sides total.
Assuming the two dice rolls are independent of one another, the probability of rolling two "1"s is (1/6)*(1/6) = 1/36.
There are 36 ways to roll two dice and only 1 way to get snake eyes.

Fill in the missing work and justification for step 3 when solving 2(x + 1) = 10.
Answer:
2(x + 1) = 10
x = 4
Step-by-step explanation:
Given:
2(x + 1) = 10
Solution:
Apply Distributive property
A*(B+C) = (A*B) + (A*C)
This means multiply 2 with x and 1
2*(x+1) = (2*x) + (2*1)
2x + 2 = 10
Use Subtraction property of equality
A = B, then A - C = B - C
Subtracting 2 from both sides:
2x + 2 - 2 = 10 - 2
2x = 8 Step 3
Use Division property of equality
It state that if you divide both sides of an equation by same nonzero number then the sides remain equal
Dividing both sides by 2
2x/2 = 8/2
x = 4
This means value of x is 4
Another method to solve this equation is:
2(x+1)=10
Use Distributive property
A*(B+C) = (A*B) + (A*C)
2*(x+1) = (2*x) + (2*1)
2*(x+1) = 2x + 2
Use commutative property
A + (-B) = (-B) + A
2x + 2 + (-2) = 2x + (-2) + 2
2x + 2 + (-2) = 10 + (-2)
2x + 2 - 2 = 10-2
2x = 8
Using division property
AX = B
AX / A = B / A
So
X = B/A
This becomes:
2x = 8
2x = 8.
Divide both sides by 2
2x / 2 = 8 / 2
x = 4

15 - 4j = 43
Help me
Answer:
I did not understand your question so this is what I know. If it is correct pls mark me brainliest.
Step-by-step explanation:
15 + -4j = 0
Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + -4j = 0 + -15
Combine like terms: 15 + -15 = 0
0 + -4j = 0 + -15
-4j = 0 + -15
Combine like terms: 0 + -15 = -15
-4j = -15
Divide each side by '-4'.
j = 3.75
Simplifying
j = 3.75
The solution of the linear equation with single variable 15 - 4j = 43 will be negative 7.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation with a single variable 'j' is given below.
15 - 4j = 43
Simplify the equation, then the value of the variable 'j' will be calculated as,
15 - 4j = 43
-4j = 43 - 15
j = 28 / (-4)
j = - 7
The arrangement of the direct condition with a single variable 15 - 4j = 43 will be negative 7.
