Which equation models the problem below if c represents the number of puppies whose eyes are closed?

True [87]

First you must take into account the variable that is being defined for this case:
c = represents the number of puppies whose eyes are closed.
We can then write the following equation:
15 = 11 + c
Rewriting the equation:
11 + c = 15
Clearing c:
c = 15-11
c = 4
4 puppies have their eyes closed
Answer:
11 + c = 15
4 puppies have their eyes closed

Find x. (Use pic for more info)

V125BC [204]

Answer:

x=75

Step-by-step explanation:

Hey There!

If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle

So essentially what I'm saying is that

2x-5=70+x

step 1 add 5 to each side

-5+5 cancels out

70+5=75

now we have

2x=70+x

step 2 subtract x from each side

x-x cancels out

2x-x=x

we're left with

x=75

Write the following coordinates where they belong in the line segments below. Consider the graph below. Which of the following c

GREYUIT [131]

Answer:

The option B (4 5/8,-2 3/4) = (4.6 , -2.75) will be the coordinates belonging in the box.

Step-by-step explanation:

A.(4 3/4,-3 3/4) = (4.75,-3.75)

B.(4 5/8,-2 3/4) = (4.6 , -2.75)

C.(4 1/4,-5 1/2) = (4.25, -5.5)

D.(4 1/8,-2 3/5) = (4.125, -2.6)

The first point of line segment is: (5.5, -4.25)

second will be (4.75,-3.75)

third will be (4.6 , -2.75)

fourth will be (4.125, -2.6)

and fifth is (3.75,-1.25)

The option C is not correct i.e not included in line segment.

The option B will be the coordinates belonging in the box.

strojnjashka [21]

Using whole numbers, fractions and decimals, the following equations have the sum of 10.

1. 6 + 3 + 1 = 10
2. 2.25 + 4.25 + 3.50 = 10
3. 7/2 + 5/2 + 8/2 = 10
4. 25/5 + 15/5 + 10/5 = 10
5. 6 + 2. 25 + 1.75 =10
6. 3.26 + 4. 52 + 2.22 = 10
7. 5+ 3 + 2 = 10
8. 3/4 + 4/2 =10

A company makes spherical tanks that store chemicals. Their standard model has a diameter of 6 meters, but a customer needs a la

Deffense [45]

Answer:

The approximate diameter of the larger tank is 8.10 meters

Step-by-step explanation:

Here, we want to calculate the diameter of the larger tank

The volume of a sphere

V = 4/3 * π * r^3

Let us calculate the volume of the standard model

That will be;

Since diameter is 6 and r = d/2

r = 6/2 = 3 meters

V = 4/3 * π * 3^3 = 36 π m^3

Now, the volume of the larger tank is 2.5 times of this;

The volume of the larger tank is 2.5 * 36 π = 90 π m^3

So we can calculate the radius of this before we calculate its diameter

4/3 * π * r^3 = 90 π

4r^3/3 = 90

r^3 = 270/4

r^3 = 67.5

r = 3x√(67.5)

r = 4.07 m

Diameter here is 2 times this

= 4.07 * 2 = 8.14
