Answer:
The store paid $800 for it
Step-by-step explanation:
let x be the value the store paid for it
120/100 * x = 960
120x = 96000
x = 96000/120
x = $800

3. Right: pointing downwards
Left: pointing upwards
4a. True
4b. True
Step-by-step explanation:
When the leading coefficient is negative the equation will either open downwards or the y-values will decrease as the x-values increase. The opposite is true for when the leading coefficient is positive. When the degree is odd one end will point downwards while the other points upwards. When the degree is even, both ends point in the same direction.
I hope this helps :)
A single die is rolled twice. Find the probability of rolling an
Odd number the first time and a number greater than 4 the second time.
Answer: 1/6
Step-by-step explanation:
A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.
Odd numbers in a die = 1, 3 and 6
Numbers greater than 4 = 5 and 6
Probability of rolling an odd number = 3/6 = 1/2
Probability of rolling a number greater than 4 = 2/6 = 1/3
We then multiply both values gotten. This will be:
= 1/2 × 1/3
= 1/6
Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.
The probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6
The sample space of a single die is
[tex]\mathbf{S = \{1,2,3,4,5,6\}}[/tex]
So, the total sample is 6
The odd numbers are
[tex]\mathbf{Odd = \{1,3,5\}}[/tex] --- 3 odd numbers.
So, the probability of selecting an odd number is:
[tex]\mathbf{P(Odd) = \frac 36}[/tex]
Simplify
[tex]\mathbf{P(Odd) = \frac 12}[/tex]
The numbers greater than 4 are
[tex]\mathbf{Greater = \{5,6\}}[/tex] --- 2 numbers greater than 4.
So, the probability of selecting a number greater than 4 is:
[tex]\mathbf{P(Greater) = \frac 26}[/tex]
Simplify
[tex]\mathbf{P(Greater) = \frac 13}[/tex]
The probability of rolling an odd number the first time and a number greater than 4 the second time is calculated as follows:
[tex]\mathbf{P = P(Odd) \times P(Greater)}[/tex]
So, we have:
[tex]\mathbf{P = \frac 12 \times \frac 13}[/tex]
[tex]\mathbf{P = \frac 16}[/tex]
Hence, the probability is 1/6

Each year, Andrea donates a total of $800 for scholarships at her local community college. This year, she wants the amount she donates for liberal arts to be three
times the amount she donates for scholarships for business. Determine the amount she will donate for each type of scholarship.
The equation is Andrea will donate $ for business scholarships and $ for liberal arts scholarships.
Answer:
The equation is [tex]L + B = \$800[/tex]
Andrea will donate $200 for business scholarships and $600 for liberal arts scholarships.
Step-by-step explanation:
Given
Represent Liberal Arts with L and Business with B
From the question, we have that:
[tex]L = 3 * B[/tex]
and
[tex]Total = \$800[/tex]
Required
Determine how much she donates for each
The total L + B is 800
i.e.
[tex]L + B = \$800[/tex]
Substitute 3 * B for L
[tex]3 * B + B = \$800[/tex]
[tex]3 B + B = \$800[/tex]
[tex]4B = \$800[/tex]
Solve for B
[tex]B =\$800/4[/tex]
[tex]B =\$200[/tex]
Recall that :
[tex]L = 3 * B[/tex]
[tex]L = 3 * \$200[/tex]

You win an online auction for a toy. Your winning bid of $35 is 70% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
Based on the amount that you bid and its percentage out of what you would pay, the amount that you were willing to pay more was $15
The winning bid of $35 is only 70% of what you would have paid at most.
Your maximum bid would therefore have been:
= 35 / 70%
= $50
The amount that you were then willing to pay more than your bid was:
= Maximum bid - Winning bid
= 50 - 35
= $15
In conclusion, you were willing to pay $15 more.

[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
Both triangles are congruent, Hence Angles of both triangle will be equal,
We have got two angles,
LP = 59°, LT = 75°
let the third angle be x
The sum of all angles of a triangle is 180°
So,
59° + 75° + x = 180
x = 46°

Step-by-step explanation:
Put all the like terms together
(4a^2 - a^2) - (7b + b) + 2ab
then simplify
(4a^2 - a^2) = 3a^2
(-7b + b) = -6b
then rewrite
3a^2 - 6b + 2ab
Answer:
3a^2 - 6b + 2ab
Step-by-step explanation:
Add like terms together so shifting the equation a little to make it easier to add:
4a^2 - 7b + 2ab - a^2 + b
4a^2 - a^2 - 7b + b + 2ab
