Lisa has $7.80 to spend on some tomatoes and a loaf of bread. Tomatoes cost $1.20 per pound, and a loaf of bread costs $1.80. The inequality 1.20x + 1.80 ≤ 7.80 models this situation, where x is the number of pounds of tomatoes. Solve the inequality. How many pounds of tomatoes can Lisa buy? A. x ≤ 8; Lisa can buy 8 pounds or less of tomatoes. B. x ≥ 5; Lisa can buy 5 pounds or more of tomatoes. C. x ≤ 5; Lisa can buy 5 pounds or less of tomatoes. D. x ≥ 8; Lisa can buy 8 pounds or more of tomatoes.
Answer:
C. [tex]x\leq 5[/tex]; Lisa can buy 5 pounds or less of tomatoes.
Step-by-step explanation:
We have been given an inequality [tex]1.20x+1.80\leq 7.80[/tex], where x is the number of pounds of tomatoes. The inequality represents amount spend by Lisa on tomatoes and loaf. We are asked to find number of pounds that Lisa can buy.
First of all, we will subtract 1.80 from both sides of our inequality.
[tex]1.20x+1.80-1.80\leq 7.80-1.80[/tex]
[tex]1.20x\leq 6.00[/tex]
Now, we will divide both sides of our inequality by 1.20.
[tex]\frac{1.20x}{1.20}\leq \frac{6.00}{1.20}[/tex]
[tex]x\leq 5[/tex]
Therefore, Lisa can buy 5 pounds or less of tomatoes and option C is the correct choice.

The side lengths of triangle ABC are written in terms of the variable p, where p ≥ 3.
Which is correct regarding the angles of the triangle?
mA > mC > mBAnswer: C) mC > mA > mB is correct regarding the angles of the triangle ABC.
Step-by-step explanation:
Given: In Δ ABC, the side lengths of triangle ABC are written in terms of the variable p, where p ≥ 3.
AB=4p-1 , AC=p+4 , BC=3p
where p+4 < 3p [as p≥3]
3p < 4p-1 [as p≥3]
⇒ 4p-1> 3p > p+4
⇒AB>BC>AC
Angle opposite to AB ,BC and AC is m∠C ,m∠A and m∠B.
Therefore mC > mB > mA [∵Angle opposite to greater side is greater]
Thus , mC > mA > mB is correct regarding the angles of the triangle ABC.

The area of a rectangular rug is given by the trinomial r squared minus 4 r minus 77r2−4r−77. What are the possible dimensions of the rug? Use factoring.
Answer:
[tex]r>\frac{4 +\sqrt{23732} }{154} \approx1.03\\[/tex]
Step-by-step explanation:
The area of the rectangular rug is given by this equation:
[tex]77r^2-4r-77[/tex]
The area must be a number greater than 0 since a negative area, or an area equal to 0 wouldn't have much sense. So:
[tex]77r^2-4r-77>0[/tex]
Let's find the roots of this equation using the quadratic formula:
[tex]r=\frac{-b\pm \sqrt{b^2-4ac} }{2a} =\frac{-(-4)\pm\sqrt{(-4)^2-(4)(77)(-77)} }{2(77)} \\\\r=\frac{4 \pm \sqrt{23732} }{154} \\\\r_1=\frac{4 +\sqrt{23732} }{154} \approx1.03\\\\r_2=\frac{4 - \sqrt{23732} }{154} \approx-0.97[/tex]
Now, let's evaluate the area for [tex]r>r_1[/tex] for example r=1.05:
[tex]A=77(1.05)^2-4(1.05)-77=3.6925>0[/tex]
The result is greater than zero, so for [tex]r>r_1[/tex] the values make sense.
Now let's evaluate the area for [tex]r_2<r<r_1[/tex] for example r=0.5 and r=-0.7:
[tex]A=77(0.5)^2-4(0.5)-77=-59.75<0\\\\A=77(-0.7)^2-4(-0.7)-77=-36.47<0[/tex]
The result is less than zero, so for [tex]r_2<r<r_1[/tex] the values don't make sense.
Now, let's evaluate the area for [tex]r<r_2[/tex] for example r=-1:
[tex]A=77(-1)^2-4(-1)-77=4>0[/tex]
The result is greater than zero, so for [tex]r<r_2[/tex] the values make sense
However, since negative values of r wouldn't make much sense (I never heard about of -8 inches for example) the possible dimensions of the rug are just:
[tex]r>\frac{4 +\sqrt{23732} }{154} \approx1.03\\[/tex]

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second.
3ft= 1yd
5280ft= 1mi
How much faster does the fish swim than the boy in yards per minutes?
The fish swims 264 yards per minute faster than the boy.
Explanation:To find out how much faster the fish swims than the boy in yards per minute, we first need to convert both speeds to yards per minute. Since 3 feet is equal to 1 yard, we can convert the fish's speed of 4.4 feet per second to yards per minute by multiplying it by (3 feet/1 yard) × (60 seconds/1 minute) = 4.4 × 3 × 60 yards per minute = 792 yards per minute. Similarly, the boy's speed of 12 miles per hour can be converted to yards per minute by multiplying it by (5280 feet/1 mile) × (1 yard/3 feet) × (1 hour/60 minutes) = 12 × 5280/3/60 yards per minute = 1056 yards per minute.
To find out how much faster the fish swims than the boy, we subtract the boy's speed from the fish's speed: 792 - 1056 = -264 yards per minute. Therefore, the fish swims 264 yards per minute faster than the boy.
I am four times as old as my brother and in two years time i will be just three times as old. in how many years will i be twice as old as my brother?
To solve the problem, set up and solve an algebraic equation. Find the value of x, then use it to determine the number of years it will take for you to be twice as old as your brother.
Explanation:To solve this problem, we can use algebraic equations. Let's assume the age of your brother is x. Since you are four times as old as your brother, your age would be 4x. In two years, your age would be 4x + 2, and your brother's age would be x + 2. According to the problem, 4x + 2 = 3(x + 2). We can solve this equation to find x, and then determine the number of years it will take for you to be twice as old as your brother.
By simplifying the equation, we get 4x + 2 = 3x + 6. Subtracted 3x from both sides, we get x + 2 = 6. Subtracting 2 from both sides, we get x = 4.
So, your brother's age is currently 4 and your age is currently 16. To determine the number of years it will take for you to be twice as old as your brother, we need to find the value of y that satisfies the equation 2(4 + y) = 16 + y. By solving this equation, we'll find that it will take 8 years for you to be twice as old as your brother.

The interior angles of a regular polygon each measure 165 degrees. how many sides does the polygon have
If a regular polygon has interior angles each measuring 165 degrees, the polygon has 24 sides. This is calculated by using the formula to find the number of sides in a regular polygon, given the angle size.
Explanation:To find out how many sides a regular polygon has, based on the size of its interior angles, you can use the formula to calculate the sum of the interior angles of a polygon:
n
= 180(
n
- 2), where
n
is the number of sides.
However, this formula gives the sum of the interior angles as a whole. Since, in a regular polygon, all angles are equal, you can then divide this sum by the known size of each angle.
So the specific formula to calculate the number of sides of a regular polygon, given the angle size, is:
n
= 360 / (180 -
angle size
).
In this case, you can substitute the angle size of 165 degrees into this formula:
n
= 360 / (180 - 165) = 360 / 15 = 24.
So a regular polygon with interior angles each measuring 165 degrees has 24 sides.

Jackson purchased some power tools totaling $1,543 using a six month deferred payment plan with an interest rate of 23.76%. He did not make any payments during the deferment period. What will the total cost of the power tools set be if he must pay off the power tools within two years after the deferment period?
$1,543.00
$1,735.63
$2,197.44
$2,746.80
The total cost of the power tools set if Jackson must pay off the tools within two years after the deferment period is $2,644.82.
To find the total cost of the power tools set after the deferred payment period, we need to consider both the initial cost of the tools and the interest accrued during the deferment period and the subsequent payment period.
First, let's calculate the interest accrued during the deferment period:
Interest = Principal × Rate × Time
Interest = $1,543 × 23.76% × (6/12) (since the deferment period is 6 months)
Interest = $1,543 × 0.2376 × 0.5
Interest = $183.78
Now, add this interest to the initial cost of the power tools:
Total cost after deferment = Initial cost + Interest
Total cost after deferment = $1,543 + $183.78
Total cost after deferment = $1,726.78
Next, we need to calculate the total amount Jackson must pay off within two years after the deferment period. This includes the principal amount and the interest accrued during the payment period. We'll use the formula for calculating the total payment for a loan with compound interest:
[tex]\[A = P(1 + r/n)^{nt}\][/tex]
Where:
A = Total amount to be paid
P = Principal amount (initial cost after deferment)
r = Annual interest rate (as a decimal)
n = Number of times interest is compounded per year
t = Time in years
In this case, we'll compound interest annually, so (n = 1), and (t = 2) years.
[tex]\[A = $1,726.78(1 + 0.2376/1)^{1*2}\][/tex]
[tex]\[A = $1,726.78(1 + 0.2376)^2\][/tex]
[tex]\[A = $1,726.78(1.2376)^2\][/tex]
[tex]\[A = $2,644.82\][/tex]
So, the total cost of the power tools set if Jackson must pay off the tools within two years after the deferment period is $2,644.82.
