Answer:
3.62 grams
Step-by-step explanation:
Multiply by .4525 to get the answer.
(For percentages you want to move the decimal to the very front. Ex. 2% = 0.02 and multiply by the number you have, in this case 8 grams.)
This should look like this: 0.4525*8=3.62

Answer:
the answer is y=30x
Step-by-step explanation:
however many inches times 30 is the consistent answer to the equation
Answer:
y=30x
Step-by-step explanation:
We can start out by writing our slope-intercept form equation: y=mx+b. In this case, our y-intercept is 0, so we can write y=mx.
Let's find the slope. We can take the points (1,30) and (2,60). We can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find our slope. Plug these values in, and we get [tex]\frac{60-30}{2-1}[/tex]. Evaluate this, and our slope is 30. So, our equation is y=30x.
Hope this helped!
Los puntajes obtenidos por un grupo de alumnos en un examen de 10 puntos son 3,5,2,6,5,9,5,2,8,6. Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el
Answer:
Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.
Step-by-step explanation:
Los Cuantiles (cuartiles, deciles, percentiles) son medidas de localización cuya función es informar del valor de la variable que ocupará la posición (en tanto por cien) que interese respecto de todo el conjunto de variables.
Los cuartiles son medidas estadísticas de posición que tienen la propiedad de dividir la serie estadística en cuatro grupos de números iguales de términos.
El primer cuartil o cuartil inferior es aquel valor de la variable tal que la cuarta parte (25%) de las observaciones son inferiores o iguales a él, y el resto (75%) es superior o igual. El segundo cuartil es la mediana, ya que se trata del valor localizado en la mitad de la distribución. Finalmente, el tercer cuartil o cuartil superior es un valor tal que las tres cuartas partes de las observaciones son inferiores o iguales a él.
En otras palabras, el primer cuartil Q1, es el valor en el cual o por debajo del cual queda aproximadamente un cuarto (25%) de todos los valores de la sucesión (ordenada); El segundo cuartil Q2 es el valor por debajo del cual queda el 50% de los datos (Mediana), el tercer cuartil Q3 es el valor por debajo del cual quedan las tres cuartas partes (75%) de los datos. Es decir, Q1, Q2 y Q3 determinan los valores correspondientes al 25%, al 50% y al 75% de los datos respectivamente. Q2 coincide con la mediana.
Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.
Jacie is serving steak and chicken she wants to have at least 20 pounds of meat. Steak is $8 per pound and chicken is $4 per pound . Jacie wants to spend at most 120 dollarss on meat
Answer:
She can get 10 pounds of steak and 10 pounds of chicken.
Step-by-step explanation:
As Jacie wants to have at least 20 pounds of meat, you can write the following equation:
x+y=20, where
x refers to the pounds of steak
y refers to the pounds of chicken
Also, since the statement indicate that the steak is $8 per pound and chicken is $4 per pound and Jacie wants to spend at most 120 dollars on meat, you can write the following equation:
8x+4y=120
So, you have the following equations:
x+y=20 (1)
8x+4y=120 (2)
Now, you can solve for x in (1):
x=20-y (3)
Then, you can replace (3) in (2) and solve for y:
8(20-y)+4y=120
160-8y+4y=120
160-120=8y-4y
40=4y
y=40/4
y=10
Finally, you can relace the value of y in (3) to find x:
x=20-y
x=20-10
x=10
According to this, the answer is that she can get 10 pounds of steak and 10 pounds of chicken.

Which graph represents a function?
Answer:
D
Step-by-step explanation:
A function is where each input (here, the input is x) corresponds to exactly one output (here, the output is y). In other words, if a function is graphed, we should be able to draw a vertical line through every single part of it that will intersect it at only one place.
Let's examine each choice.
(A) Well, if we draw a vertical line through the graph, it will obviously intersect the entire line - which is an infinite number of intersections, so this is not a function.
(B) If we draw a vertical line through the portion of the graph that lies near the positive x-axis, we note that it will intersect twice, so this is not a function.
(C) If we strategically draw a vertical line through the y-axis, we see it will intersect two times, so this is not a function.
(D) We can draw a vertical line through any portion of this graph and know that it will only intersect once.
Therefore, the answer is D.
Answer:
D

Find the circumference and area of a circle to the nearest hundredth. Use 3.14 for pie. Round to the nearest hundredth if necessary. The diameter is 52.
Answer:
Circumference = 163.28 unitsArea = 2,122.64 units²Step-by-step explanation:
Circumference
Circumference of a circle is calculated by the formula:
= π * diameter
= 3.14 * 52
= 163.28 units
Area
Area of a circle is calculated by the formula:
= π * radius²
Radius = DIameter / 2
= 52 / 2
= 26 units
Area = 3.14 * 26 * 26
= 2,122.64 units²

When Josh and Sean were each 5 years old, Josh was 1.5 inches taller than Sean. Josh grew at an average rate of 2.75 inches per year from the time that he was 5 years old until the time he was 13 years old. Josh was 63 inches tall when he was 13 years old. How tall was Sean when he was 5 years old?
A. 39.5 inches
B. 42.5 inches
C. 44.75 inches
D. 47.75 inches
Step-by-step explanation:
josh is 1.5 inches taller than sean
so, let sean's height be x
sean = x
josh = x + 1.5
each year josh gain 2.75 inches, and now he's 13 so how many year has passed
13 y - 5 y = 8
then how tall he grew
2.75×8=22
x + 1.5+22=63
x=63-22-1.5
x=39.5

y = x - 4. 2x + 3y = -17 substitution method
Answer:
x = -1
y = -5
Step-by-step explanation:
y = x - 4 y = x - 4
2x + 3y = -17 y = (-1) - 4
2x + 3(x - 4) = -17 y = -1 - 4
2x + 3x - 12 = -17 y = -5
5x - 12 = -17
5x - 12 + 12 = -17 + 12 Check
5x = -5 2x + 3y = -17
5x/5 = -5/5 2(-1) + 3(-5) = -17
x = -1 -2 + -15 = -17
-17 = -17

The number of vertices in a prism is twice the number of vertices of one of the bases. How many vertices does one of the bases of a regular prism with 14 faces and 36 edges have?
Answer:
24
Step-by-step explanation:
The computation of the number of vertices does one of the base of regular prism is shown below:
V + F = E + 2
V + 14 = 36 + 2
V + 14 = 38
V = 38 - 14
= 24
What's the answer to this?
Answer:
the answer is 3.26and3.51
Step-by-step explanation:
the difference between them is 0.25 so by adding 3.01+0.25=3.26
3.26+0.25=3.51
3.51+0.25=3.76
3.76+0.25=4.01
