Find the slope between (-7,16) and (-15,-2)
Answer:
9/4
Step-by-step explanation:
The slope formula is
m = ( y2-y1)/(x2-x1)
= ( -2 -16)/( -15 - -7)
= ( -2-16)/( -15+7)
= -18/-8
= 9/4
Leila is paid $10 plus $8 an hour. She was paid $66. How many hours did she work??
Use the inverse operations to solve the given equations..
Answer:
Leila is paid $10 plus $8 an hour
She was paid $66
Let the number of times be x
According to the problem,
10+8x=66
8x=66-10
8x=56
x=56/8
x=7
She worked for 7 hours.
7 hours is the right answer.A bag contains 18 balls to green five black eight blue one brown one red and one white if 17 balls of a move from the bag at random what is the probability that a brown ball has been removed
Answer:
[tex]P(Brown) = 0.0556[/tex] or [tex]P(Brown) = \frac{1}{18}[/tex]
Step-by-step explanation:
Given
[tex]Total = 18[/tex]
[tex]Green = 2[/tex]
[tex]Black = 5[/tex]
[tex]Blue = 8[/tex]
[tex]Brown = 1[/tex]
[tex]Red = 1[/tex]
[tex]White = 1[/tex]
Required
Determine the probability of selecting a brown ball
This is calculated as thus:
[tex]P(Brown) = \frac{Brown}{Total}[/tex]
Substitute values for Brown and Total
[tex]P(Brown) = \frac{1}{18}[/tex]
The answer can be in fraction or solved further as;
[tex]P(Brown) = 0.0556[/tex]
John states that the products of two real numbers is a real number. Extending this to imaginary numbers. John states that the product of two imaginary numbers must be imaginary. Is his statement correct? Explain
Answer:
No, this is a wrong statement.
Step-by-step explanation:
In the context, it is given that John states that the product of two the real numbers provides a number that is real. This is always true, the product is always a real number of two real number.
But the product of any two imaginary numbers is not a imaginary number, the product is always a real number.
So John provides a wrong statement in case of product of any two imaginary numbers.

Tori devotes all of her income to the consumption of peanut butter and jelly. She has just discovered that at her current level of consumption the marginal utility of a jar of peanut butter is 5 and the marginal utility of a jar of jelly is 7. Which statement is TRUE? a. To maximize her total utility, Tori should consume less of both goods. b. To maximize her total utility, Tori should consume more peanut butter and less jelly. c. To maximize her total utility, Tori should consume more of both goods. d. There is not enough information provided to justify a change in Tori's level of consumption.
To maximize her total utility, Tori should consume less of both goods statement is TRUE. Thus option A is correct.
What is marginal utility?The additional satisfaction a shopping experience from owning one extra unit of an item or a service is known as marginal utility. Economists utilize the idea of marginal utility to estimate the quantity of a good that buyers will purchase.
Progressive taxation are frequently defended using the law of diminished marginal utility. In the context of consumption, a jar of peanut butter has a marginal utility of 5, while a jar of jelly has a marginal utility of 7.
The purchaser should spend their income so that every penny spent on goods or services results in the same marginal benefit in order to get the most value. Therefore, option A is the correct option.

lcm of 420 and 210
MATHS
Answer:
LCM = 420
Step-by-step explanation:
What is the LCM of 210 and 420?
Step 1:
Find the prime factorization of 210
210 = 2 × 3 × 5 × 7
Step 2:
Find the prime factorization of 420
420 = 2 × 2 × 3 × 5 × 7
Step 3:
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:
LCM = 2 × 2 × 3 × 5 × 7
Step 4:
The required LCM
LCM = 420
Therefore, we conclude that:
LCM = 420
1/2x - 7 = 1/3(x - 12)
Answer:
i think the answer is x= 9/35
Step-by-step explanation:
Answer:
x = 18
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] x - 7 = [tex]\frac{1}{3}[/tex](x - 12)
Multiply both sides by 6 ( the LCM of 2 and 3 ) to clear the fractions
3x - 42 = 2(x - 12) ← distribute
3x - 42 = 2x - 24 ( subtract 2x from both sides )
x - 42 = - 24 ( add 42 to both sides )
x = 18

Look at this set of ordered pairs:
(3, -13)
(3, 2)
(18,-5)
Is this relation a function?
yes
no
Answer:
NoStep-by-step explanation:
Given ordered pairs:
(3, -13) (3, 2) (18,-5)There is a repeat of domains (3) with different range (-13 and 2) but the function can't have repeat domains so it is not a function
Answer:
It would not be a function
Step-by-step explanation:
A function has no repeating 'x' values
(3,-13) x=3
(3,2) x=3
(18,-5) x=18
So, because there is more than one of the same 'x' value (3) it is not a function.
I hope that helped :)
Explain or show how you could find 5÷13
Answer:
bus stop division really hard to show on here.
13/5
13 does not go into 5 so put a decimal point after the 5
13/5.000 carry the 5 over to the zero
13 goes into 50 3 times with 11 left over. carry the 11 over to the next zero. 13 goes into 110 8 times with 6 left over. carry over to the next zero. keep adding zeros and carrying over until the 13 goes into a number equally.

A contractor purchases 4 dozen pairs of padded work gloves for $53.76. She incorrectly calculates the unit price as $13.44 per pair for the expense report. What is the correct unit price. What is the error
Answer:
1. The correct unit price of a pair = $1.12.
2. The error is taking the unit as 4 units instead of 48 units.
Step-by-step explanation:
a) Data and Calculations:
Cost of 4 dozen pairs of padded work gloves = $53.76
Each dozen pairs of the padded work gloves = $13.44 ($53.76/4)
Each pair of the padded work gloves = $1.12 ($13.44/12 or $53.76/48)
b) A dozen is made up of 12 units of something. A dozen is an accepted unit of measurement that has persisted since time immemorial. It originated from the practise of counting numbers in 12 instead of the current number system of 10.
