Answer:
78%
Step-by-step explanation:
Ok to solve this we can write this as
80 = [tex]\frac{73+82+85+83+x}{5}[/tex]
We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%
Your grade is the average of all of your scores hence the divided by 5
We next multiply both sides of the equation by 5 to get
400 = 72+82+85+83+x
400= 322+ x
78 = x
He must get a 78% minimum on his next test to get 80%
Hope that helps!

Find the surface of this triangular prism please
Answer:
270cm²
Step-by-step explanation:
The formula is given as
S = bh × l (s1 + s2 + h)
l = 7cm
h = 5cm
s1 = 12 cm
s2 = 13cm
b = 12 cm
Surface Area = 12 cm × 5 cm × 7 cm(12 cm+ 13 cm+ 5cm)
= 60cm² × 7 cm(30 cm)
= 60cm² + 210 cm²
= 270 cm²
write the rate and unit rate. 609 kilometers in 7 hours ???
Answer:
The rate is 609 kilometers per 7 hours.
The unit rate is 609/7 = 87 kilometers per hour.
Step-by-step explanation:
Should be right
Answer:
87 Kilometers per hour and if by unit rate you mean how many miles they are doing a miniute then it is 1.45 kilometers per hour

Which graph best represents y = -x2 + 6x - 1?
Si X es una variable aleatoria de tipo continuo… ¿Es posible definir el índice de asimetría de Fisher? ¿Por qué?
Answer:
Primero, para un caso discreto, el índice de asimetría de Fisher se calcula como:
[tex]\frac{\sum(xi - M)*n_i}{N*S_x}[/tex]
Donde:
xi son los i-esimos distintos valores de nuestro conjunto de datos.
M es la media
N es el numero de datos
ni es la frequencia absoluta de cada xi
Sx es la desviacion tipica
Podemos ver que en el caso discreto, escribimos el coeficiente con una sumatoria, lo cual realmente no podemos hacer para una variable continua.
Lo que si podemos hacer para una variable continua, es una integral, donde como esta vez tenemos una variable continua, podemos definir una función:
f(X) = frequencia absoluta para X.
Y escribir el coeficiente como:
[tex]\frac{\int\limits^a_b {(X - M)*f(x)} \, dx }{N*S_x}[/tex]
Entonces si, es posible definir el índice.

Solve by factoring
2n^2+12n+18
Answer:
Step-by-step explanation:
d/dn(2 n^2 + 12 n + 18) = 4 (n + 3)
Indefinite integral:
integral(18 + 12 n + 2 n^2) dn = (2 n^3)/3 + 6 n^2 + 18 n + constant
Global minimum:
min{2 n^2 + 12 n + 18} = 0 at n = -3
⛔️NO LINK JUST WANT ANSWER NONE OF THAT BIT.L STUFF⛔️The biggest frog on record

goliath frog was found i
km from the nearest water,
about how many jumps
would he have to take to

Answer:
The answer would be 333.334 jumps.
Step-by-step explanation:
So remember, there are 1000 meters in 1 kilometer. The frog can jump 3 meters. The nearest water is 1 kilometer. So, lets divide 1 km(1000m) by 3m:
1000/3
=
333.34
This is the answer.

HELP ME WITH THIS PLEASE.
THANKS LOVE U GUYS SO MUCH.
Answer:
48.
Step-by-step explanation:
1). <C = 74 because it forms a supplemetary angle 180- 106 = 74.
2). We know that the sum of all the angles in a triangle is 180 so we need to add them.
3). 4y + 3y +22 + 74= 180
4). simplify 7y +96=180
5). isolate y so we must subtract 96 from either side.
6). 7y= 84 now divide by 7 on each side. 84/7 = 12.
7). Now we know y = 12 and that angle A is equal to 4y.
8). <A = 4(12) now distrubute
9). <A= 48 degrees

Danielle's pool table is 5 feet wide and 8 feet long. Danielle wants to replace the felt on
the pool table. The felt costs $2.20 per square foot. How much would it cost in total to
replace the felt on the pool table?
Answer:
$88
Step-by-step explanation:
cost to replace the felt = Area of a rectangle x felt cost per square foot
Area = length x width
5 x 8 = 40
cost of replacement = 40 x 2.2 = 88

Nick was thinking of a number. Nick adds 11, then divides by 6 to get an answer of -7. What was the original number?
Answer:
-53/6
Step-by-step explanation:
x + 11 / 6 = -7
Subtract 11/6 from both sides to isolate x.
x = -53/6
write an equation for a function that has vertical asymptotes at x=3 & x=-10
Answer:
[tex] \frac{5}{ {x}^{2} + 7x - 30} [/tex]
Step-by-step explanation:
We can write a rational function.
We need to make sure our denominator both have zeroes at 3 and 10.
Set an equation equal to zero to find the function
[tex]0 - x = 3[/tex]
[tex]0 - x = - 10[/tex]
[tex]0 - ( - 3) = = 3[/tex]
[tex]0 - 10 = 10[/tex]
So we would represent that's as
[tex]x - 3[/tex]
and
[tex]x + 10[/tex]
Multiply the two binomial together.
[tex](x - 3)(x + 10) = {x}^{2} + 7x - 30[/tex]
Let our numbetator be any interger.
Use any equation as long as the quadratic is the denominator and the interger is the numerator.
[tex] \frac{5}{ {x}^{2} + 7x - 30 } [/tex]

An airplane takes off at an angle of 15 degrees with the ground. To the nearest 10 feet, how far has the airplane flown when it has covered a horizontal distance of 1800 feet?
Answer:
1863.5 feets
Step-by-step explanation:
Using Trigonometry :
The distance, d in the attached diagram can be obtained using the trigonometric relation :
Cosθ = adjacent / hypotenus
Cos 15° = 1800 / d
0.9659258 = 1800 / d
0.9659258 * d = 1800
d = 1800 / 0.9659258
d = 1863.4971 feets
The distance covered to the nearest 10 feet = 1863.5 feets
A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the observation tower's shadow? Write your answer as a whole number or a decimal. Do not round.
Answer: 9 yards
Step-by-step explanation:
Given
The maple tree is 16 yards tall and its shadow is 12 yards tall
Suppose the angle made by the maple tree is x
[tex]\Rightarrow \cos x=\dfrac{12}{16}[/tex]
For the tower also, the angle made by the tower and its shadow is x
Suppose the length of the shadow is y
[tex]\Rightarrow \cos x=\dfrac{y}{12}[/tex]
Substitute the value of [tex]\cos x[/tex]
[tex]\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}[/tex]
