What is the net force here and what direction will the object accelerate ?
Answers
since there is force being applied in opposite directions, the net force is found by subtracting the 2
100 - 10 = 90 N ( Net Force)
and because the higher force is pushing the box to the right, the direction will accelerate to the right.

the point (7, 1)
case A.) y = 5x + 4
if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1

39 is not 1---------> the point does not belong to the line
case B.) y = -x + 8
if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=-7+8------> y=1--------> the point belongs to the line
case C.) y = x - 10
if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=7-10------> y=-3
-3 is not 1---------> the point does not belong to the line
case D.) y = -4x + 3

The number of events we have in this situation is 2, one for each die. Each die has a 1/6 chance of landing a six, and we need two to win. So, the probability of this event is 1/6 times 1/6, or 1/36.

Answer:
B) The initial value is 22, and the rate of change is 15.
Step-by-step explanation:
The first point is located at (22, 54). This means the initial value is 22.
The rate of change is found using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Using the first two points, we have

George is playing a board game and hopes to roll a sum of 5 he tosses a pair of number cubes what is the probability that the sum of the numbers tossed will be five
Answers
The probability of rolling a sum of 5 with two dice is 1/9, as there are 4 favorable outcomes out of the 36 possible outcomes when rolling two dice.
The student asked about the probability of rolling a sum of 5 using two fair, six-sided dice (also known as number cubes). To find this probability, we need to consider all possible outcomes that result in a sum of 5 and divide it by the total number of possible outcomes when rolling two dice.
By examining the possible ways to get a sum of 5, we have the following pairs: (1,4), (2,3), (3,2), and (4,1). There are 4 favorable outcomes. Since each die has 6 faces, there are a total of 6 x 6 = 36 possible outcomes when rolling two dice. Thus, the probability of rolling a sum of 5 is 4/36, which reduces to 1/9.
To conclude, the probability to roll a sum of 5 on two dice is 1/9.
a cylinder and a cone have the same base and height.The cylinder can hold about 4,712 cm3 of sand .Jared says that the cone can hold about 1,178 cm3 of sand.Which explains where Jared is correct
Answers
Jared is correct because the volume of a cone that has the same base and height as a cylinder is one-third the volume of the cylinder. This is due to the 1/3 factor in the formula for the volume of a cone. Therefore, the cone would indeed hold about 1,178 cm³ of sand.
Explanation:Jared is indeed correct in his statement. The volume of a cone is found by using the formula 1/3 * base area * height, while the volume of a cylinder is found by using the formula base area * height. In this case, both the cone and the cylinder have the same base and height. However, the key difference lies in the 1/3 factor of the formula for a cone. This means that a cone with the same base and height as a cylinder would hold only one-third the volume of the cylinder.
In this case, the cylinder can hold about 4,712 cm³ of sand. As the cone is one third the size of the cylinder, it can hold about 1,178 cm³, which is precisely one third of the cylinder's volume, thus Jared's statement is correct.

A circle has a center at (1,-2) and radius of 4. Does the point (3.4,1.2) lie on the circle? Justify your answer.
Answers
The point (3.4, 1.2) lies on the circle with center at (1, -2) and radius of 4, as the distance from the point to the circle's center is exactly equal to the circle's radius.
The question asks if the point (3.4, 1.2) lies on a circle with a center at (1, -2) and a radius of 4. To determine this, we can use the distance formula, which calculates the distance between two points in a coordinate plane. The distance formula is √((x_2 - x_1)^2 + (y_2 - y_1)^2), where (x_1, y_1) and (x_2, y_2) are the coordinates of the two points. In this case, the center of the circle is (1, -2) and the point in question is (3.4, 1.2).
To see if the point lies on the circle, we check if the distance from the point to the center equals the circle's radius. Calculating: √((3.4 - 1)^2 + (1.2 - (-2))^2) = √((2.4)^2 + (3.2)^2) = √(5.76 + 10.24) = √16 = 4. Since this distance is exactly 4, which is the circle's radius, the point (3.4, 1.2) does indeed lie on the circle.

Dave has a life insurance policy with $2.2 million benefit. If this money was put into an account with a 3.4% interest rate, how much income can his beneficiaries expect i case Dave dies?
A $74, 800
B $20, 600
C. $60, 000
D $40, 000
Answers
Answer:
Step-by-step explanation:
The maximum value can reach $74, 800 if Dave Dies.
What is Exponential GrowthInsofar as they use compound interest, life insurance premiums are equivalent to bank interest rates. We may use the exponential growth formula to get the insurance policy payout because they are compound interests. Those being the following,
Given:
T = [tex]a(1+r)^t[/tex]
Where:
T is the final payout, a is the initial amount, r is the interest rate in decimal form and t is the time.
So, T = [tex]2200000(1+ 0.034)^t[/tex]
let Dave dies after 2 years of buying his life insurance the beneficiaries will get the following payout.
T = [tex]2200000(1+ 0.034)^2[/tex]
T= 2200000 ( 1.069156)
T = $23,52,143.2
So, the maximum value can reach $74, 800.

Staci is attending a music festival. The ticket to the festival costs $87.96. Staci plans to purchase $30.00 t-shirt from the event for close friends. she is taking $200.00 to the festival. what is the maximum number of t-shirts can purchase?
Answers
After purchasing the festival ticket, Staci has $112.04 remaining from her $200 budget. Each T-shirt costs $30, so she can buy a maximum of 3 T-shirts.
Explanation:The student asked how many
T-shirts Staci can purchase at a music festival considering she has a budget of $200, and she also needs to buy a ticket and possibly T-shirts for her friends.
First, we need to subtract the cost of the festival ticket from Staci's total budget which is $200.00 - $87.96 = $112.04 remaining. Now, if each T-shirt costs $30.00, we can find the maximum number of T-shirts she can purchase by dividing the remaining money by the cost of one T-shirt.
$112.04 / $30.00 = 3.734.
Since Staci cannot buy a fraction of a T-shirt, she can purchase a maximum of 3 T-shirts with the remaining budget.

quick I need help quick Morgan rode her bike. 2 kilometers from her house to her friend's house from her friend's house she rode 600m in all going to and from the library then she rode back home how many meters did Morgan like in all
Answers
Morgan rode her bike a total of 4600 meters after combining the distances from her house to her friend's, to and from the library, and back to her house.
To determine how many meters Morgan cycled in total, we first need to convert all distances into the same unit. Morgan rode 2 kilometers from her house to her friend's house, which is equal to 2000 meters. Then, she rode 600 meters in total going to and from the library. Since she needs to return home, she would ride the initial 2000 meters back. Therefore, the total distance Morgan cycled is the sum of these three distances.
Calculation
Distance from home to friend's house: 2000 meters
Traveling to and from the library: 600 meters
Distance from friend's house back to home: 2000 meters
Adding these distances gives us the total distance Morgan rode:
Total Distance = 2000m + 600m + 2000m = 4600 meters.
