Answer:
2/3
Step-by-step explanation:
When we divide two fractions, such as 1/5 ÷ 3/10, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
what is 5 and one half minus three and one third?
Answer:
1 2/3
Step-by-step explanation:
5 1/2 = 11/2 x 3 = 33/6
3 1/3 = 10/3 x 2 = 20/6
30 - 20 = 10/6 = 1 4/6 = 1 2/3
Answer: 2 1/6
Step-by-step explanation:
5 1/2 - 3 1/3
=
5 3/6 - 3 2/6
=
5 - 3 = 2
3/6 - 2/6 = 1/6
= 2 1/6

Solve 2/3x- 1/5>1
Answer:
x > 9/5
Step-by-step explanation:
Step 1: Write inequality
2/3x - 1/5 > 1
Step 2: Solve for x
Add 1/5 to both sides: 2/3x > 6/5Divide both sides by 2/3: x > 9/5Here we see that any x value greater than 9/5 will work.
1 Two functions are shown below. Function A Function B x 0 3 5 y 5 3x 1 2 y 3 9 13 Which statement correctly describes the rates of change of the two functions? A The rate of change is 2 for both Function A and Function B. B The rate of change is 3 for both Function A and Function B. C The rate of change is greater for Function A than for Function B. D The rate of change is greater for Function B than for Function A.
Answer:
D The rate of change is greater for Function B than for Function A
Step-by-step explanation:
A function shows the relationship between a dependent variable and an independent variable. A linear function is given as y = mx + b, where m is the rate of change, y is the dependent variable, x is the independent variable and b is the value of y when x = 0.
Function B is given by y = 3x + 2. Comparing with y =mx + b gives m = 3. Therefore the rate of change of function B is 3.
Function A has x: 0, 3, 9 and y:3, 9, 13. Using the points (0,3) and (3, 9), we an get the equation of the function. The formula is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{9-3}{3-0}(x-0)\\ \\y-3=2x\\\\y=2x+3[/tex]
Function A is given by y = 2x + 3. Comparing with y =mx + b gives m = 2. Therefore the rate of change of function A is 2.
The rate of change is greater for Function B than for Function A

Answer:
w=4
Step-by-step explanation:
The surface area of a prism is SA= 2lw+2lh+2hw
We are trying to find out the width if the SA is 240 square inches, length is 12 inches, and the height is 5 inches. Let's plug these numbers into the equation.
240=(2*12*w)+(2*12*5)+(2*5*w)
24w+120+10w
240= 34w+120
-120 -120
120= 34w
120/34 = 34w/34
w is approximately equal to 3.5 which can be rounded to 4
w=4

It has been estimated that only about 30% of California residents have adequate earthquake supplies.

HowmanyCaliforniaresidentsdoyouexpecttoneedtosurveyuntilyoufindaCaliforniaresidentwhodoesnot have adequate earthquake supplies? g. How many California residents do you expect to need to survey until you find a California resident who does have adequate earthquake supplies?
Answer:
Step-by-step explanation:
We are given that 30% of California residents have adequate earthquake supplies.
a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance
B) x can take value 1 ,2 ,3 ......
C)The distribution of random variable is geometric distribution with parameter p=0.3
The pmf of geometric distribution is
[tex]P(X=x)=0.3(1-0.3)^{x-1} , x=1,2,3...[/tex]
D)P(X=1) or P(X=2)=P(X=1)+P(X=2)
P(X=1) or P(X=2)=[tex]0.3(1-0.3)^{1-1}+0.3(1-0.3)^{2-1}=0.51[/tex]
E)
[tex]P(X \geq 3)=1-P(X<3)\\P(X \geq 3)=1-(P(X=1)+P(X=2))\\P(X \geq 3)=1-0.51\\P(X \geq 3)=0.49[/tex]
F)
[tex]E(X)=\frac{1}{p}[/tex]
p is the resident who does not have adequate earthquake supplies.
p = 1-0.3 = 0.7
[tex]E(X)=\frac{1}{0.7}=1.42[/tex]
G)[tex]E(X)=\frac{1}{q}=\frac{1}{0.3}=3.33[/tex]

Once there was a monkey who found a jar full to the brim with cookies. He eyed them hungrily, and shoved his hand into the jar, grabbing as many as he little paw could hold. But when he went to remove his hand from the jar, he couldn’t get it out. His hand was too full of cookies. Unwilling to lose the cookies, and yet not able to get his hand out, the monkey burst into tears.

rewrite the linear equation 2x=1/3y-9 in slope- intercept form.
y=. x. +
Answer:
y = 6x + 27
Step-by-step explanation:
The required linear equation would be y = 6x + 27 in the slope-intercept form.
What is a Linear Function?A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.
It represents the line's slope-intercept form, which is written as y = mx+ c.
Linear equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing.
The linear equation is given in the question
⇒ 2x = (1/3)y - 9
We have to rewrite the equation in the slope-intercept form.
⇒ 2x = (1/3)y - 9
Multiply by 3 both sides of the above equation,
⇒ 6x = y - 27
Rearrange the term of y to get
⇒ y = 6x + 27
Therefore, the required linear equation would be y = 6x + 27 in the slope-intercept form.
