Answer: I think Value of x is 8 I’m not sure
Answer:
8
Step-by-step explanation:
the right angle is 90 degrees, the line is 180 so 180-90 is 90 so 6X+4 + 5X-2= 90 you can counter the -2 by using the +4 so it just becomes +2 90-2=88 so the answer is 8
Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15
Answer:
Roots are : 1, -7 and -7
Step-by-step explanation:
When we put x = -1 in F(x) it is equal to 0
Thus, (x + 1) is factor of given function.
When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)
factorizing the work x² - 6x - 7 by middle term splitting.
> x² - 6x - 7 = x² - 7x + x - 7
> x(x - 7) + 1(x - 7)
> (x + 1) (x - 7)
then, x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)
x = -1, -1, 7 the factor.

How many mg of a metal containing 38 percent nickel must be combined with 5 mg of pure nickel to form an alloy containing 68 percent nickel? Which of the following equations could be used to solve this?
Answer:
the Answer is C
Step-by-step explanation:
The metal needs to be 16/3 mg in weight to get the required alloy.
We can use the third equation,
(a(0.38) + 5(1.00))/(a+5) = 68/100
to solve the problem.
What do we mean by Percentage?A percentage is a ratio where a number is shown as a fraction with respect to 100 parts of it. To remove the percentage sign we divide the number by 100.
How do we solve the given problem?We are asked to mix a certain quantity of metal in mg containing 38 percent of nickel to 5 mg of pure nickel such that the new alloy contains 68 percent of nickel.
Let the quantity of metal taken to be 'a' mg.
∴ Nickel provided by the metal is 38% of a,
or, (38/100)*a
or, a(0.38)
We took 5 mg of pure nickel so it is 100 percent pure,
∴ Nickel in the alloy from pure nickel = 100% of 5
or, (100/100)*5
or, 5(1.00)
Total weight of the alloy = a + 5
Total nickel in the alloy = a(0.38) + 5(1.00)
We are said that the alloy constitutes 68 percent of nickel,
∴ (a(0.38) + 5(1.00))/(a+5) = 68%
or, (a(0.38) + 5(1.00))/(a+5) = 68/100
This is the equation needed to find the quantity of metal used to make the alloy. It is the same as option 3.
On solving the equation we get that the required quantity of the metal is 16/3 mg.

2385.60
Can someone please help me figure out how to solve this?
Answer:
B. 48m²
Step-by-step explanation:
The formula for volume is length (base) times width times height, or LWH. If you break the shape into three separate areas, you can figure out the volume for each part and then add it up.
The large part on the bottom is 7m long, 2m across. Since we know the entire shape is 4m tall and the indent is 2m deep, we know that the height for the bottom part will also be 2m. 7 · 2 · 2 = 28.
The block on the left is 2m tall, 2m across, and its width is also 2m as shown by the measurement on the bottom-right. 2 · 2 · 2 = 8.
Finally, the block on the right is 2m tall, 3m across, with a width of 2m. 3 · 2 · 2 = 12. And when you add it all up, 28 + 8 + 12 = 48. Hope this helps! Feel free to ask any questions!

there are 6 boys and 5 girls in the debate class. kids are being selected to go present their work without getting opt-out where is the probability that a boy will be selected to present twice?
Answer:
30%?
Step-by-step explanation:
6 boys, 5 girls
first selection is a 6/11 chance it's a boy.
second seletion is a 6/11 chance it's a boy.
6/11 times 6/11 is... 0.2975 or about a 30% chance ( i think)
Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

A. As the number of swimmers increases, the amount of water in the pool tends to decrease.
B. As the number of swimmers increases, the amount of water in the pool tends to increase.
C. As the number of swimmers increases, the amount of water in the pool tends to stay the same.
D. There is no relationship between the number of swimmers and the amount of water in the pool.
The answers is B
Step-by-step explanation:
EDGE2021
As the number of swimmers increases, the amount of water in the pool tends to decrease.
Thus, option (A) is correct.
Given:
A scatter plot which shows he amount of water in the pool and the number of swimmers.
Now, from the scatter plot it can be seen that
As the number of swimmer increases there is no such change in amount of water.
There is only increase in a amount of water when the number of swimmers were between 60 to 70.
But at last the plot shows that the amount of water decrease.
Therefore, number of swimmers increases, the amount of water decrease.
Thus, option (A) is correct.

Truman is buying a teddy bear and flowers for his girIfriend. Flowers Galore charges $13 for the teddy bear and $0.75 per flower. Famous Florist charges $9 for the teddy bear and $1.25 per flower. Which inequality represents the number of flowers, f, Truman would need to buy to make Flowers Galore the cheaper option?
The inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f
How to determine the inequality?At Flowers Galore, we have:
Teddy bear = $13
Flower = $0.75
At Famous Florist, we have:
Teddy bear = $9
Flower = $1.25
So, the expressions are:
Flowers Galore: 13 + 0.75f
Famous Florist: 9 + 1.25f
When Flowers Galore is the cheaper option, we have:
13 + 0.75f < 9 + 1.25f
Hence, the inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f
