Answer:
Fastest train: 65 mph
slowest: 55 mph
Step-by-step explanation:
Divide 480 by 4
=120
To find average speed divide 120 by 2
=60
call the speed of the slowest train y.
y+(y+10)=120
2y=110
y=110/2=55
y+10=65

Find the surface area of the ball shown. Use 3.14 for π.
Radius is 13 cm.
Answer:
Hi! answer: 530.66
Step-by-step explanation:
To find area for circles you have to do radius × radius × pi so our radius is 13 so 13 × 13 = 169
169 × 3.14 = 530.66 So that's our answer hope that helps!

A sculpture is made of solid copper in the shape of a cone. The sculpture is 67 inches tall, and its base has a radius of 15 inches. If copper costs 1.06$ per cubic inch, how much did the copper for the sculpture cost?
Use 3.14 for Pi, and do not round your answer.
Answer:
$16,725.21
Step-by-step explanation:
To get the cost of the copper used for the sculpture, we must first determine the volume of the object which is given as a cone
Recall that the volume V of a cone
= 1/3Pir^2h
where r is the base radius and h is the height
Given that the sculpture is 67 inches tall, and its base has a radius of 15 inches, the volume of the sculpture
= 1/3 * 3.14 * 15^2 * 67
= 15,778.5 cubic inch
If copper costs 1.06$ per cubic inch, then the cost of the copper for the sculpture
= 15,778.5 * 1.06
= $16,725.21

Answer:
4 buses
Step-by-step explanation:
There are 173 basketball fans
one bus can hold 46 fans
Hence the number of buses needed can be calculated as follows
= 173/46
= 3.76
= 4
Hence 4 buses are needed

A warehouse worker is stacking boxes. The height of each box is 20 centimeters. She cannot stack the boxes higher than 5 feet.
1 inch 2.54 centimeters, 1 foot = 12 inches
What is the maximum number of boxes the warehouse worker can stack? Enter the answer in the box.
boxes
Answer:
7 boxes
Step-by-step explanation:
We'll begin by writing convert 5 ft to in. This can be obtained as follow:
1 ft = 12 in
Therefore,
5 ft = 5 ft × 12 in / 1 ft
5 ft = 60 in
Next, we shall convert 60 in to cm. This can be obtained as follow:
1 in = 2.54 cm
Therefore,
60 in = 60 in × 2.54 cm / 1 in
60 in = 152.4 cm
Finally, we shall determine the maximum number of boxes the ware house worker can stack.
Total height = 152.4 cm
Height of 1 box = 20 cm
Number of box =?
Number of box = total height / height of 1 box
Number of box = 152.4 / 20
Number of box = 7
Therefore, the warehouse worker can only stack a maximum of 7 boxes

Answer:
180
Step-by-step explanation:
area of a trapezoid = [tex]\frac{a+b}{2}h[/tex]
where a = base 1
b = base 2
and h = height
This is what we are given
base 1 = 23
base 2 = 37
and height = 6
That being said we plug in the given values into the formula
[tex]A=\frac{37+23}{2} 6\\23+37=60\\\frac{60}{2} =30\\30*6=180[/tex]
Hence the area of the trapezoid is 180 square feet

Step-by-step explanation:
Si a la mitad de un número le restas su tercera parte, y, a este resultado, le sumas 85/2,
obtienes el triple del número inicial. ¿De qué número se trata?
Answer:
x = 15
Step-by-step explanation:
Llamaremos x al número que buscamos, entonces:
la mitad de x es x/2, la tercera parte es x/3, y el triple del número es 3*x
De acuerdo al problema :
(x/2 - x/3 ) + 85/2 = 3*x
Esta es una ecuación de primer grado pasamos a resolverla.
( 3*x - 2*x ) /6 + 85/2 = 3*x
x/6 + 85/2 = 3*x
( x + 255)/6 = 3*x
x + 255 = 18*x
17*x = 255
x = 255/17
x = 15

Missy and Bill were asked to evaluate the expression -3(-2 + 5).
Answer:
-9
Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
using BODMAS, our mathematical operation begins with the bracket.
it implies that from -3(-2+5), we solve the bracket.
-2+5=3
then our mathematical operation is the 'of' operation.
it implies that -3(3) = -9
Answer is -9
