Solve the equation.
4(z – 3) = 22
Answer: z=6
Step-by-step explanation:
4(z-3)=2z
4z-12=2z subtract 2z from both sides
2z-12=0 add 12 to both sides
2z=12 divide 2 to both sides
z=6

Answer:
7000degrees/sec
Step-by-step explanation:
The question is not properly structured. Here is the correct question.
A pitcher's arm rotates at a speed of 7 degrees per millisecond (degrees/ms) . At what speed does the pitcher's arm rotate in degrees/s?
Before we proceed, you must know that we will be applying the following conversion;
1 milliseconds = 10⁻³secs
Given
Speed of pitcher's arm in degree per milliseconds = 7deg/ms
Required
We are to express in degree/sec
Using the conversion formula above;
[tex]7deg/ms = \dfrac{7^0}{1millisecs} \\\\converting \ to \ deg/s\\7deg/ms = \dfrac{7^0}{1millisecs} \times \dfrac{1}{10^{-3}s}\\7deg/ms = \dfrac{7^0}{10^{-3}s}\\[/tex]
[tex]7deg/ms = 7^0 \times 1/0.001s\\7deg/ms = 7^0 \times 1000/s\\7deg/ms = 7000^0/sec\\[/tex]
Hence the value in degree/sec is 7000degrees/sec
The volume V of gas varies inversely to the pressure P. The volume of a gas is 200 cm3 under pressure of 32 kg/cm2. What will be its volume under pressure of 40 kg/cm2?
Answer:
V = 160 cm³ when P = 40 kg/cm²
Step-by-step explanation:
V = k / P
Where,
V = volume
P = pressure
k = constant of proportionality
The volume of a gas is 200 cm3 under pressure of 32 kg/cm2
V = k / P
200 = k / 32
Cross product
200 × 32 = k
6,400 = k
k = 6,400
What will be its volume under pressure of 40 kg/cm2?
V = k / P
= 6,400 / 40
= 160
V = 160 cm³

An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away (from the airplane to the run away). Calculate the airplane’s angle of decent. (Hint: the angle of decent is the same as the angle of depression.)
Given :
An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away.
To Find :
The airplane’s angle of decent.
Solution :
Height of plane, h = 2600 m.
Horizontal distance of airplane from vertices is, d = 56 km = 56000 m.
Let, angle of depression is Ф.
So,
[tex]tan \ \phi = \dfrac{56000}{2600}\\\\tan \ \phi = 21.54\\\\\phi = 87.34^o[/tex]
Therefore, the angle of decent is 87.34°.
Hence, this is the required solution.
The area of a rectangle is less than 81 square centimeters. The length of the rectangle is 9 centimeters and the width is x centimeters. Select the possible value(s) of x.
Answer:
Given
The area of a rectangle is less than 81 square centimeters
length 9cm
width =x cm
Step-by-step explanation:
Area of rectangle=length ×width
= 9×X
Area of rectangle is less than 81 cm^2
So 9x-81=0
X=81/9
X=9
So the value of xis 9

Step-by-step explanation:
I did it on a calculator.
Show your work: Solve for b, where A is the area of a rectangle, b is the length of the base of the rectangle, and h is the height of the rectangle. Ab h
Answer:
[tex]b = \dfrac{A}{h}[/tex]
Step-by-step explanation:
Given the formula for calculating the area of the rectangle as;
A = bh where;
b is the length of the base of the rectangle, and;
h is the height of the rectangle
Required
Make b the subject of the formula
Given
[tex]A = bh\\\\divide \ both \ sides \ by \ h\\\dfrac{A}{h} = \dfrac{bh}{h}\\ \dfrac{A}{h} = b\\Re-arrange;\\b = \dfrac{A}{h}[/tex]
Hence the value of b in terms of A and h is expressed as [tex]b = \dfrac{A}{h}[/tex]

Sylvia plans to place 617 stamps in an album. Each page of the album holds 5 stamps. She uses division to find out how many full pages she will have. How many full pages will she have?
Answer:
123 full pages
Step-by-step explanation:
Given
[tex]Total\ Stamps = 617\ stamps[/tex]
[tex]Each\ Page = 5\ stamps[/tex]
Required
Determine the number of full page
To do this, we simply divide the total stamps by stamps in each page;
[tex]Pages = \frac{Total\ Stamps}{Each\ Page}[/tex]
[tex]Pages = \frac{617}{5}[/tex]
[tex]Pages = 123.4[/tex]
Then we record only the quotient
The quotient is the digits before the decimal
[tex]Pages = 123[/tex]
Hence, she has 123 full pages

Michelle drew a purple line that was 1/2 of an inch long then she drew a green line that was 1/6 of an inch long how much longer what is the purple line than the green line
Answer:
[tex]\dfrac{1}{3}[/tex]
Step-by-step explanation:
Given length of purple line = [tex]\frac{1}{2}\ inch[/tex]
Given length of green line = [tex]\frac{1}{6}\ inch[/tex]
To find:
How much longer is the purple line than the green line ?
Solution:
To find the required length, we have to subtract the length of green line from the length of purple line.
i.e.
The required answer =
[tex]\frac{1}{2}-\frac{1}{6}\\\text{Taking LCM of 2 and 6, we get 6}\\\Rightarrow \dfrac{3-1}{6}\\\Rightarrow \dfrac{2}{6}\\\Rightarrow \bold{\dfrac{1}{3}}[/tex]
Therefore, the answer is:
Purple line is [tex]\frac{1}{3}[/tex] of an inch longer than the green line.

What is the answer to the questions A. B. C. ?? Please help this is a summative
Answer:
A) 12.5 per hour. Slope: y = 12.5x
B)500x or Next - Now = 500x = 1,360
C) y = 12.5 + 360
Step-by-step explanation:
A) 360 in account, 40 hour then she has 860.
Find the unit amount so to find how much she gets per hour you have to find the unit amount.
Since she had a total of 860 but she already had 360, subtract 860 - 360 = 500. Now divide by 40: 500/40 = 12.5. (that's how much she gets per hour.)
B) Next , Now
Next she will make 500 every 40 hours so after that she'll have 1.360 in her account.
Equation: Next,Now
So it's the rate of change which will be 500 per 40 hours. so the rate of change is 500x
C) equation:
Rate of change 12.5 per hour
Y- intercept is 360 since that's what she had in her account so,
y = 12.5x + 360
