Answer:
51 or above
Step-by-step explanation:
He already averages more then 78. But he at least needs a 51 in order for him to average 78. For him to get more than that he just needs a 52 or higher.
78 x 5 = 390
95 + 92 + 84 + 68 = 339
339/ 4 = 84.75 ( just to let you know the average before #5 )
390 - 339 = 51
51 is that last score needed

Recall the Pythagorean theorem, , where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse. Apply the Pythagorean theorem to right triangle . Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar. By counting square units, the length of side is 8 units, and the length of side is units. By the Pythagorean theorem, the length of the hypotenuse, side , is units.
Supposing that the other square has a length of 6 units, applying the Pythagorean Theorem, it is found that:
The length of the hypotenuse side is of 10 units.
What is the Pythagorean Theorem?The Pythagorean Theorem is a geometry axiom that relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In the context of this problem, we have that the legs have lengths defined as follows:
One leg is of 6 units.The other leg is of 8 units.Hence the length of the hypotenuse can be found as follows:
h² = 6² + 8²
h² = 36 + 64
h² = 100
h = sqrt(100)
h = 10 units.
What is the missing information?
This problem is incomplete and could not be found on any search engine, hence we are going to suppose that the other leg of the triangle has a length of 6 units.

Harry puts money into an account which pays 6% compound interest per year. If he puts £23000 in the account for 5 years how much more interest will he earn altogether?
The interest that Harry will earn altogether if he puts £23000 in the account for 5 years is £386,538,000.
Compound interest refers to the interest added to a loan or deposit. It is the concept that we use every day the most regularly. For an amount, compound interest is computed using both the principal and accrued interest. This is the primary difference between compound and simple interest.
Compound interest is the type of interest that is calculated using both the principal and the interest that has accumulated over the preceding period. In contrast to simple interest, compound interest does not factor in the principal when calculating the interest for a subsequent period.
In mathematics, compound interest is frequently referred to as C.I.
It is possible to compute interest using both the initial principle and interest that has accumulated over time.
Compound interest is calculated mathematically as Amount - Principal, where
Amount = Principal*(1 + (r/n))t, where r is the rate of interest, n is the number of times interest is compounded annually, and t is the number of years, and Principal is the initial amount deposited.
Given, Principal = £23000
Rate of interest = 6%
Number of times interest is compounded per year = 1
Number of years = 5
Using above literature, Amount = 23000(1 + (6/1))^5 = 23000*16807 = £ 386,561,000.
Thus, Compound Interest = £386,561,000 - £23000 = £386,538,000.

what does B equal???
Answer:b = 2
Step-by-step explanation:
Let u = (1, −1, 3, 5) and v = (2, 1, 0, −3). Find scalars a and
b so that au + bv = (1, −4, 9, 18).
The value of the scalars a = 3 , and b = -1 .
In the question ,
it is given that
u = (1, −1, 3, 5) and v = (2, 1, 0, −3)
and the equation au + bv = (1, −4, 9, 18)
Substituting the first value of u that is u=1 and substituting the first value of v that is v=2 ,
we get a+2b=1 ....(i)
Now , Substituting the second value of u that is u= -1 and substituting the second value of v that is v=1 ,
we get -a+b= -4 ...(ii)
Solving the equations (i) and (ii)
Adding both the equations we get
a-a+2b+b=1-4
3b= -3
b= -1
a+2b=1
put b= -1
a+2(-1)=1
a-2=1
a=3.
Therefore , the value of the scalars a = 3 , and b = -1 .

Fill in the blank with a value so that the solution will be as indicated. Each blank can be a different value. Then explain how you know.
Considering the given systems of equations, the expressions to obtain the desired results are filled as follows:
No solution: -2x + 5 + 11x = 9x + 6. (11 and 6 fill the blanks). One solution: -2x + 5 + 8x = 9x + 6. (8 and 6 fill the blanks). Infinitely many solutions: -2x + 5 + 11x = 9x + 5. (11 and 5 fill the blanks). When does a system of equations has no solution?A system of equations will have no solution if it can be written in the following format:
0x = constant different of 0.
Hence:
-2x + 5 + 11x = 9x + 6(the final number can be any number different of 5)
As:
9x + 5 = 9x + 6
0x = 1 -> division by 0 does not exist, hence no solution.
When does a system of equations has one solution?A system of equations will have one solution if it can be written in the following format:
cx = d, c different of 0.
Hence:
-2x + 5 + 8x = 9x + 6(the final number on the left side can be any number different of 11)
6x + 5 = 9x + 6
-3x = 1
x = -1/3 (lone solution).
When does a system of equations has infinitely many solutions?A system of equations will have infinitely many solutions if it can be written in the following format:
0x = 0.
Hence:
-2x + 5 + 11x = 9x + 5
9x + 5 = 9x + 5
0x = 0 (0/0 results in any value).
