The answer for your question is d

Answer:

D)15+15+10+10+6+6

Step-by-step explanation:

the formula to find the SA of a rectangular prism is:

2(lw)+2(lh)+2(hw)

where

l=length

w=width

and

h=height

let's substitute the values,3,2,and 5 into the equation

2(5*3)+2(5*2)+2(3*2)=62

62 is the SA

from the options:

10+6=16

10+10+6+6=32

15+15+10+10+6=56

and

15+15+10+10+6+6=62

so option D is correct

Answer:

26 degrees.

Step-by-step explanation:

180 - 154 = 26

Step-by-step explanation:

[tex]100xh=1,150\qquad\text{divide both sides by}\ 100x\neq0\\\\\dfrac{100xh}{100x}=\dfrac{1,150}{100x}\\\\\boxed{h=\dfrac{115}{x}}[/tex]

To solve the equation \( 1,150 = 100 \times x \times h \) for \( h \), you want to isolate \( h \) on one side of the equation. Follow these steps:
**Step 1: Understand the equation**
The equation is saying that 100 times the product of \( x \) and \( h \) is equal to 1,150.
**Step 2: Isolate \( h \)**
To solve for \( h \), you need to get \( h \) by itself on one side of the equation. Right now \( h \) is being multiplied by \( 100 \times x \). To undo this, you'll divide both sides of the equation by \( 100 \times x \).
**Step 3: Perform the division**
Divide both sides of the equation by \( 100 \times x \):
\[
\frac{1,150}{100 \times x} = \frac{100 \times x \times h}{100 \times x}
\]
**Step 4: Simplify both sides**
On the right-hand side, \( 100 \times x \) in the numerator and \( 100 \times x \) in the denominator cancel each other out:
\[
\frac{1,150}{100 \times x} = h
\]
**Step 5: Result**
You are left with \( h \) by itself on one side of the equation and \( \frac{1,150}{100 \times x} \) on the other:
\[
h = \frac{1,150}{100 \times x}
\]
Now \( h \) has been solved in terms of \( x \), and you can find the value of \( h \) if you know the value of \( x \) by simply substituting that value into this equation and performing the calculation.

Answer:6/36

Step-by-step explanation:

The probability of rolling a number less than 5 and even on a die is 1/2.

To find the probability of rolling a number less than 5 and even, we need to determine the number of outcomes that satisfy both conditions and divide it by the total number of possible outcomes.

There are three outcomes that satisfy both conditions: {2, 4, 6}. The total number of possible outcomes is six since a die has six sides.

Therefore, the probability of rolling a number less than 5 and even is 3/6, which simplifies to 1/2.

Answer:

To find the circumference of a circle you have to multiply Pi (3.14) with the diameter of the circle.

You need to find circumference of the circle first

Answer:

The center is (-5,1)

and

the radius is 3

Step-by-step explanation:

The given equation of the circle is

[tex](x+5)^2+(y-1)^2=9[/tex]

We can rewrite this equation in the form;

[tex](x-h)^2+(y-1)^2=r^2[/tex]

This implies that;

[tex](x--5)^2+(y-1)^2=3^2[/tex]

When we compare, we get;

(h,k)=(-5,1) which is the center and r=3 the radius.

The answer is:

The center of the circle is located on the point (-5,1) and the radius is equal to 3 units.

To determine the center and the radius of a circle from its equation, we need to look for "h" and "k", being "h" the x-coordinate of the center and "k" the y-coordinate the center, then, calculate the radius.

Since we are given the ordinary equation of the circle, we can find the radius and the center directly.

The ordinary equation is:

[tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]

Where,

h is the x-coordinate of the center

y is the y-coordinate of the center

r is the radius.

So, we are given the circle:

[tex](x+5)^{2} +(y-1)^{2} =9[/tex]

Which is also equal to:

[tex](x-(-5))^{2} +(y-(1))^{2} =9[/tex]

Where,

[tex]h=-5\\k=1[/tex]

[tex]r^{2}=9\\\sqrt{r^{2}}=\sqrt{9} \\r=3units[/tex]

Hence, the center of the circle is located on the point (-5,1) and the radius is equal to 3 units.

Ordered pairs that satisfy the given equation:

x  0  1  2  3  4

y  5  3  1  -1  -3

To find the x-intercept, we will substitute y = 0 and solve for x to get:

[tex]0 = -2x + 5[/tex]

[tex] -2x = -5[/tex]

[tex]x = 5/2[/tex]

x-intercept = (5/2, 0)

To find the y-intercept, we will substitute x = 0 and solve for x to get:

[tex]y = -2(0) + 5[/tex]

[tex]y = 5[/tex]

y-intercept = (0, 5)

Answer: option d.

Step-by-step explanation:

To create a table of five ordered pairs that satisfy the equation, you need to give values to the variable "x" and substitute these into the function to find the corresponding value of "y":

For [tex]x=-2[/tex]

[tex]y = -2(-2) + 5=9[/tex]

For [tex]x=-1[/tex]

[tex]y = -2(-1) + 5=7[/tex]

For [tex]x=0[/tex]

[tex]y = -2(0) + 5=5[/tex]

For [tex]x=1[/tex]

[tex]y = -2(1) + 5=3[/tex]

For [tex]x=2[/tex]

[tex]y = -2(2) + 5=1[/tex]

Then, you can make the table:

x   -2  -1  0  1  2

y   9  7  5  3  1

To find the  x-intercept, substitute [tex]y=0[/tex] into the function and solve for "x". Then:

[tex]0 = -2x + 5\\\\x=\frac{-5}{-2}\\\\x=\frac{5}2}[/tex]

This is: ([tex]\frac{5}{2}[/tex], 0)

To find the  y-intercept, substitute [tex]x=0[/tex] into the function and solve for "y". Then:

[tex]y= -2(0) + 5\\\\y=5[/tex]

This is: (0,5)

72 fish total. 12 fish in each tank.

_________________________

(g+t)n=f

g=Goldfish

t=Tetras

n=Number of fish tanks

*If I got it wrong, let me know*

Final answer:

The total number of fish in the tanks is 72.

Explanation:

To find the total number of fish in the tanks, we need to multiply the number of tanks by the sum of the goldfish and Tetras in each tank. Based on the information given, there are 6 tanks, and each tank has 7 goldfish and 5 Tetras.

So, the total number of fish (f) in the tanks can be calculated as:

f = (7 goldfish + 5 Tetras) * 6 tanks

f = (7 + 5) * 6

f = 12 * 6

f = 72

Therefore, the total number of fish in the tanks is 72.

Answer: the meaning of data is pretty simple

Step-by-step explanation: data is something you record or write down after you do a experiment. after you jot it down you can show your work to other scientests to show what you know. I hope this helps!

The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

Let's look at an example.

6, 8, 9, 14, 23

To find the mean of the data set shown above,

start by adding the numbers.

Adding the numbers, we get 60.

60 will be divided by the number of numbers in the set, which is 5.

So, 60 divided by 5 is 12.

So the mean of this data set is 12.

Each pencil box usually contains same amount of pencils. In given context  the number of pencils in five boxes is 10 pencils.

Suppose that its given that 'a' boxes contains 'b' items, then, assuming that each box contains 'x' items, then

[tex]x + x + ... + x \text{ (a times)} = b\\\\x \times a = b\\\\x = \dfrac{b}{a}[/tex]

Thus, there are 'b/a' items contained in each box.

Since there are six pencils in three boxes, let there are 'x' pencils in one box, then we have:

[tex]x + x + x = 6\\3 \times x = 6\\\\\text{Dividing both sides by 3}\\\\x = \dfrac{6}{3} = 2[/tex]

Thus, there are 2 pencils in each pencil box.

Thus, for 5 boxes, we get [tex]2 \times 5 = 10[/tex] pencils.

Thus,

In given context  the number of pencils in five boxes is 10 pencils.

Final answer:

By using proportional reasoning, if three boxes contain 36 pencils, then five boxes would contain 60 pencils.

Explanation:

If thirty-six pencils are packed in three boxes, then there are twelve pencils per box because 36 divided by 3 equals 12.

To find out how many pencils are packed in five boxes, we multiply twelve pencils (the number of pencils per box) by five boxes.

Therefore, 12 pencils/box × 5 boxes = 60 pencils in five boxes.

This is a simple proportional reasoning problem, often encountered in mathematical exercises in school.

Answer:

Step-by-step explanation:

How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )

We know that each cousin appear 2 or 3 times overall.

If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos

If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos

We know there's exactly 5 cousins per photo...

so we have to find a multiple of 5 cousins/photos that is between 16 and 24.

The only possibility is 20 cousins/photos.  20 / 5 = 4 photos.

Final answer:

Tania took 4 selfies with her cousins. Each cousin appeared in exactly 2 selfies, with some appearing a third time to account for 16 total cousin appearances divided by 5 cousins per selfie.

Explanation:

The problem presented is a combinatorial puzzle involving selfies and cousins. Since each cousin is in either 2 or 3 pictures, we can try to minimize the number of pictures by assuming each cousin is in exactly 2 pictures first. If there are 8 cousins and 5 cousins per picture, then by multiplying 8 by 2 (every cousin appears exactly 2 times), we get 16 cousin appearances in total.

Since each selfie has 5 cousins, we divide the total cousin appearances by the number of cousins per picture: 16 / 5, which results in 3.2. However, since it's not possible to have a fraction of a picture, we need at least 4 selfies to cover all appearances. Yet, this leaves us 4 extra appearances (because 4 pictures would mean 20 cousin appearances in total).

These 4 extra appearances account for the fact that some cousins appear 3 times instead of just 2. Therefore, Tania must have taken 4 selfies with her cousins to cover the 16 cousin appearances with some cousins appearing an additional third time.
