The total of Jenny's 5 tests = 375
If she wants an average of 77 then
her 6 tests must total 6 x 77 = 462
462 - 375 = 87 which is what Jenny
must score on the sixth test for an
average of 77.
:-)
Answer:
79
Step-by-step explanation:
Sum of 4 test for Average of 82 must be 82 x 4 which is 328.
Subtract previous 3 scores from 328:
328 - (98 + 83 + 68)
328 - 249 = 79
She needs a 79
A jar had 88 coins. 1/3 of the coins were silver. How many coins were gold?
Answer:
There are 66 gold coins in the jar
Step-by-step explanation:
Let the number of silver coins = X
Then the number of gold coins = 3X (as there are 1/3 number of silver coins as gold)
Total coins =88
Total coins = silver coins + gold coins
Total coins = X + 3X = 88
Total coins = 4X = 88
X = 88/4
X = 22
No. Of silver coins = 22
No. Of gold coins = 3X = 3×22
No. Of gold coins = 3X= 66
Check
Total coins = 3X + X = 88
66+22 = 88
88 = 88
Hope it helps...
Have a great day :P
Answer:
Hello There!!
Step-by-step explanation:
Let the number of silver coins be x and gold coins be 3x which add up to 4x. Make an expression and add 88 with 4x so 4x=88
x=22(88÷4).
So x=22[silver coins]
3x=66(22×3) [gold coins]
hope this helps,have a great day!!

3n^3 - 12n^2 + 2n - 8
(show the work pls..)
Answer:
The answer will be ( n - 4 ) ( 3n² + 2 ).
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.
[tex] {3n}^{2} (n - 4) + 2(n - 4)[/tex]
2) Factor out the common term n - 4.
[tex](n - 4)( {3n}^{2} + 2)[/tex]
Therefor, the answer is ( n - 4 ) ( 3n² + 2 ).

Yolanda ha comprado un coche por 8.200 euros. Lo ha pagado en tres partes. Primero pagó un 60% del valor del coche, después el 25% y por ultimo el resto ¿ cuánto pagó Yolanda la última vez?
Answer:
1.230 euros
Step-by-step explanation:
De la pregunta anterior se nos dice que:
Yolanda compró un coche por 8.200 euros. Lo ha pagado en tres partes.
Paso 1
Sea el porcentaje de la suma total de dinero = 100%
Primero pagó el 60% del valor del auto, luego el 25% y finalmente el resto.
Dejemos que el resto esté representado por x
Por eso;
Primera parte + Segunda parte + Tercera parte = 100%
60% + 25% + x = 100%
x = 100% - (60% + 25%)
x = 100% - 85%
x = 15%
Paso 2
¿Cuánto pagó Yolanda la última vez?
La última vez = Tercera parte y esto se calcula como:
15% de 8.200 euros
= 15/100 × 8.200 euros
= 1.230 euros
Yolanda pagó 1.230 euros la última vez.
A loan requires that the 4% interest be compounded monthly for five years find the number of compounding periods
Answer:
60 compounding periods
Step-by-step explanation:
The proper formula for compound interest is A = P(1 + r/n)^(nt), where r is the interest rate as a decimal fraction, n is the number of times that interest is compounded in 1 year, and t is the number of years.
In this problem, we don't need to calculate the Amount, but only the number of compounding periods. That is nt, which here is 12*5, or 60.

please hurry i have 5mins
Answer: I think its A
Step-by-step explanation:
The given function is increasing from 1 to ∞. Therefore, option A is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
From the given graph, the vertex is (1, -2)
For a function y = f(x), if the value of y increases on increasing the value of x, then the function is an increasing function.
Here, the function is increasing from 1 to infinity.
Therefore, option A is the correct answer.

The area of a rectangular dance floor is 8 1/4
square yards, and its width is 3 1/2 yards. What is the patio's length in yards
A 54
B 2
C 4:
D 5
Answer:
2 5/14 yards
Step-by-step explanation:
Area of the rectangular floor = Length * Width
Given
Area = 8 1/4 square yards
width = 3
1/2 yards
Required
Length
Length = Area/width
Length = (8 1/4)/(3 1/2)
Length = 33/4 ÷ 7/2
Length = 33/4 * 2/7
Length = 33/14
length = 2 5/14 yards
This gives the required length

Step-by-step explanation:
Use Pythagorean theorem
Base²+ altitude² = hypotenuse²
Base² + (√3)² = (2√3)²
Base² + √3 *√3 = 2√3 *2√3
Base² + 3 = 4*3
Base² + 3 = 12
Base² = 12 - 3
Base² = 9
Base = [tex]\sqrt{9}=\sqrt{3*3} =3[/tex]

Find the area of the polygon.
Answer: 72
Step-by-step explanation: 6*2=12 6*10=60 Normally you would divide by 2 to get triangles but since there are two of each, you don't.
Answer:
Solution given:
diagonal 1=AC=6+6=12units
diagonal 2=BD=2+10=12units
area of polygon (rhombus)=½*(diagonal 1*diagonal 2)
=½(12*12)=12*6=72square units
Area=72square units
The Smiths want to fence their square garden, which has an area of 289 square feet. What would be the minimum amount of fencing needed to complete the project? A) 68 feet of fencing B) 17 square feet of fencing C) 289 feet of fencing D) 17 feet of fencing
Answer:
68 feets of fencing
Step-by-step explanation:
Given that:
Area of square garden = 289 ft²
The side length of square garden can be obtained thus :
Area of a square = s²
Where s = side length
s² = 289
s = sqrt(289)
s = 17
Perimeter of square garden : 4s
Perimeter = 4* 17 = 68 feets

Leslie has a box of markers. There are 3 black,
4 red, 2 blue, 1 brown, 2 purple, 2 yellow and 5
green markers. Create a sample space of possible
outcomes for choosing a marker. Is this a simple or compound event?
Answer:
Sample space: {Black, Red, Blue, Brown, Purple, Yellow, Green}
Simple event
Step-by-step explanation:
Sample space is a list of all the possible outcomes.
This is a simple event because you are only doing one event, such as choosing marbles from a bag.
A compound event would be multiple simple events, such as flipping a coin and rolling a dice.
