Answer: First Solution
Step-by-step explanation:
We can solve this by using the Quadratic Formula, which is
(-b±√b²-4ac)/2a
First off we can find the discriminant. Replacing b with 7, a with 2, and c with -5 gives us a discriminant of 89. But there are two solutions with the discriminant 89.
The second deciding factor would be finding the denominator, which is 2a. Replacing a with 2 gives us 4.
We already know the solution is the first one, but it's important to find the value of the first part of the numerator, -b. Using that we can tell that it's -7, and not 7.
If you roll a number cube, what is the probability that you will roll an even number?
Answers
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Probability is calculated as
P = [tex]\frac{favourable outcome}{number of outcomes}[/tex]
A favourable outcome is an even number , that is 2, 4, 6 , a total of 3
number of outcomes = 6 , that is 1, 2, 3, 4, 5, 6
Then
P( even number) = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

what is the value of x?
Answers
Answer:
45??
Step-by-step explanation:
Answer:
x = 15√2
Step-by-step explanation:
Since the two angles on the triangle are the same, we can conclude that x is equal to the side that is adjacent to it too ( not the hypotenuse).
We will have x = a to use this pythagorean theorem as follows.
We will get the equation,
a = b
where
a^2 + b^2 = c^2
so,
a^2 + a^2 = c^2
2a^2 = 30^2
2a^2 / 2 = 900 / 2
√a^2 = √450
a = √450
a = 15√2

8%/year, and the rest at 7.5%/year. After
1 year, these investments earn $242 in
simple interest. How much did he invest
at each rate?
Answers
Answer:
Step-by-step explanation:
let Rehman invests in 8%=$x
simple interest=x*0.08*1=0.08 x
investment in 7.5%=$(3050-x)
simple interest=(3050-x)*0.075*1=228.75-0.075x
total interest=0.080 x+228.75-0.075 x=0.005x+228,75
0.005x+228.75=242
0.005 x=242-228.75
0.005 x=13.25
x=13.25 /0.005=2650
invested at 8%=$2650

the distance between two points it is calculated with the formula
d=√[(y2-y1)²+(x2-x1)²]
then
d=√[(2-2)²+(-6-5)²]
d=√[(0)²+(-11)²]
d=√[121]
d=√121-----------> d=11 units
the answer is 11 units,
Also, The segment is horizontal because the y-coordinates are the same. To find the distance, you can count the spaces between the points. The segment is 11 units long.

6. Alima made bubble tea using milk, tea and pearls in the ratio of 4:3:1. If the total weight of the bubble tea made is 1560 g, find the weight of each ingredient used?
Answers
Milk, tea and pearls in the ratio of 4:3:1 -> The milk = 4x, tea = 3x and pearls = x
So, 1560g is equal to 4x + 3x + x = 8x
x = 1560 / 8 = 195
3x = 195 x 3 = 585
4x = 195 x 4 = 780
So, she used 780g of milk, 585g of tea and 195g of pearls.
Answer:
Milk= 780g
Tea= 585g
Pearls= 195g
Step-by-step explanation:
So we know that all together there is 1560g. So what we do is add the ratio numbers together which is 4+3+1. This gives us 8. Next, what we can do is how much is 1 (ratio). So we do 1560g/8. This gives us 195g. Now the last step is to multiply 195g with each ratio number given. So milk is represented as 4. So therefore milk would be 4 multiplied by 195g. This means milk= 780g. Tea = 3 multiplied by 195g. Thus, this gives us 585g. The last one which is pearls is 195g as it is multiplied by 1. To check the answer, you can add the three numbers which are 780g+ 585g+195g= 1560g.

8. The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to buy a new boat for his business. Every day, his route takes him 22.5 miles against the current and back to his dock, and he needs to make this trip in a total of 9 hours. He has a boat in mind, but he can only test it on a lake where there is no current. How fast must the boat go on the lake in order for it to serve the ferry operator’s needs? *
Answers
Step-by-step explanation:
Let x represent the speed of the boat on the lake or in still water.
The speed of the current in a river is 6 mph. This means that if the boat goes upstream against the speed of the current, its total speed would be (x - 6)mph. If the boat goes downstream against the speed of the current, its total speed would be (x + 6)mph.
Time = distance/ speed
Every day, his route takes him 22.5 miles each way against the current and back to his dock, and he needs to make this trip in a total of 9 hours. This means that the time taken to travel upstream is
22.5/(x - 6). The time taken to travel downstream is
22.5/(x + 6)
Since the total time is 9 hours, it means that
22.5/(x - 6) = 22.5/(x + 6)
Cross multiplying, it becomes
22.5(x + 6) + 22.5(x - 6) = 9
Multiplying through by (x + 6)(x - 6), it becomes
22.5(x - 6) + 22.5(x + 6) = 9[(x + 6)(x - 6)]
22.5x - 135 + 22.5x + 135 = 9(x² - 6x + 6x - 36)
22.5x + 22.5x = 9x² - 324
9x² - 45x - 324 = 0
Dividing through by 9, it becomes
x² - 5x - 36 = 0
x² + 4x - 9x - 36 = 0
x(x + 4) - 9(x + 4) = 0
x - 9 = 0 or x + 4 = 0
x = 9 or x = - 4
Since the speed cannot be negative, then x = 9
Answer:
x=9
