Lynette has a metal doorstop with the dimensions shown.
Each cubic centimeter of the metal in the doorstop has a mass
of about 8.3 grams. Find the volume of the metal in the
doorstop. Then find the mass of the doorstop.
Answers
Volume = 105in³
Mass = 871.5g
To find the volume of the metal we can find the area of a base, and multiply it by the prism's width.
The base is 30cm in area, and the width is 3.5cm, which makes the volume 105in³
The mass of the doorstop can be found by just multiplying the grams per cubic centimeter by the volume, which would be 871.5g

To find the area of a circle we can use the following equation

A 25 foot ladder is set against the side of a house so that it reaches up 15 feet. If Camden grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 12 ft.) Round to the nearest tenth of a foot.
Answers
Answer:
The ladder will reach a height of 9.8 foot
Step-by-step explanation:
Given
Initial Position
[tex]L = 25ft[/tex] --- Length of the ladder
[tex]h = 15ft[/tex] --- height against the wall
New position
[tex]L = 25ft[/tex] --- Length of the ladder
[tex]B = 3ft[/tex] --- 3 feet farther from the wall
Required
Determine the new height the ladder will reach
The question is illustrated using the attached image.
Where
[tex]\triangle ABC[/tex] represents the initial position of the ladder
[tex]\triangle DBE[/tex] represents the new position of the ladder
The new height is represented with BD
Using Pythagoras theorem on [tex]\triangle DBE[/tex]
[tex]DE^2 = BE^2 + BD^2[/tex]
[tex]BE = BC + CE = 20 + 3 = 23[/tex]
[tex]BD = x[/tex]
[tex]DE =25[/tex] --- length of the ladder
So, the expression becomes
[tex]25^2 = 23^2 + x^2[/tex]
[tex]625 = 529 + x^2[/tex]
Collect like terms
[tex]x^2 = -529 + 625[/tex]
[tex]x^2 = 96[/tex]
Take positive square roots of both sides
[tex]x = \sqrt{96[/tex]
[tex]x = 9.8ft[/tex] --- approximated

Calcula y comprueba las ecuaciones: plisss lo necesito alguien me puede ayudar a) 2X = 6 b) 10 + Z = 20 c) P + 9 = 11 d) 3X + 8 = + 29 e) 2U + 8 = 10
Answers
Answer:
a) x=3
b) z=10
c) P= 2
d) X=7
e) U=1
Step-by-step explanation:
Resolver una ecuación consiste en hallar los valores de la variable que hacen cierta la igualdad.
a) 2x= 6
El coeficiente es el número junto a la variable. En este caso, el coeficiente es 2. Para eliminar este número en la expresión 2x, debido a que la variable x esta multiplicada por 2, deberás dividir ambos lados de la ecuación entre 2, debido a que la operación opuesta de la multiplicación es la división.
(2x)÷2=6÷2
x= 3
Comprobar la solución de una ecuación se hace al remplazar la variable en una ecuación con el valor de la solución. La solución debería satisfacer la ecuación cuando se ingresa en esta.
En este caso:
2*3= 6
6=6
b) 10 + z= 20
En este caso se debe sumar o restar la constante que se encuentra acompañando a la variable en ambos lados de la ecuación de manera de aislar el término de la variable. En este caso:
10 - 10 + z= 20 -10
z= 10
Comprobación:
10 + z=20
10 + 10=20
20=20
c) P + 9= 11
P +9 - 9= 11 -9
P=2
Comprobación:
2 + 9= 11
11=11
d) 3X + 8 = 29
En este caso, se suma o resta la constante en ambos lados de la ecuación y luego se elimina el coeficiente de la variable mediante la división o multiplicación. Esto es:
3X + 8 - 8= 29 - 8
3X= 21
3X ÷3= 21÷3
X=7
Comprobación:
3*7 + 8=29
21+8=29
29=29
e) 2U + 8= 10
2U + 8 - 8= 10 -8
2U= 2
2U ÷2= 2÷2
U=1
Comprobación:
2*1 + 8= 10
2 + 8= 10
10=10

210 is what percent of 500?
Answers
Answer:
42
hope this answer helps you!
Explanation:
Step 1: We make the assumption that 500 is 100% since it is our output value.
Step 2: We next represent the value we seek with X.
Step 3: From step 1, it follows that 100%= 500.
Step 4: In the same vein, X%= 210.
Step 5: This gives us a pair of simple equations:
100%= 500(1)
X%=210(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/X%= 500/210
Step 7: Taking the inverse (or reciprocal) of sides yields
X%/100= 210/500
X= 42%
Three pairs of shoes cost $108. If each pair costs the same, how much does each one cost?
A.$32
B.$34
C.$36
D.$38
Answers
Answer:
C: 36
Step-by-step explanation:
There are 3 pairs of shoes. They all cost the same. Since these shoes add up to 108 dollars, they basically multiply by three to get to 108. (3x=108) If you want to figure out the cost of one shoe you just have to reverse the process by using division. So just do simple division by dividing 108 by three (108/3=x) and there is your answer, 36.
108 divided by 3 is 36

One card is drawn from a standard 52-card deck and then replaced, and then a second
card is drawn. What is the probability that the first card is a red 8 and the second is a
black 10?
Answers
Answer:
1/676
Step-by-step explanation:
In a deck of cards there are 2 red 8's ( 8 of diamonds and 8 of hearts)
P( red 8) = number of red 8's/ total
= 2/52 = 1/26
Then we put the card back so there are still 52 cards
In a deck of cards there are 2 black 10's ( 10 of spades and 10 of clubs)
P( black) = number of black 10's/ total
= 2/52 = 1/26
Multiply the probabilities together
P( red 8, black 10) = 1/26 * 1/26 = 1 /676

Mark and his three friends ate out at Applebee’s. Their bill totaled $52. If they left the server a 20% tip, how much would each person pay if they split the bill evenly? *
Answers
Answer:
$15.71 each
Step-by-step explanation:
I just followed the answer sheet
Answer:
$13.05
Step-by-step explanation:
Given: Mark and his 3 friends = 4 Total cost = $52, percent off: 20%
To find: How much each person would pay if they split the bill evenly.
Solution:
Firstly, since they left the server a 20% tip, multiply 20% by the total cost. Convert it to a fraction. Note: you're adding 20% to the total cost.
[tex]\frac{20}{100}[/tex] + [tex]\frac{52}{1}[/tex]
= [tex]_{52.2}[/tex]
Now, that is done, let's divide the newly found cost by the four friends.
[tex]\sqrt[4]{52.2}[/tex]
= [tex]{13.05}[/tex]
So, they would pay $13.05 evenly.
