Answer:
a) 53 is prime
Step-by-step explanation:
Answer:
C,D
Step-by-step explanation:
A Prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself

Answer:
∠L = 54°
Step-by-step explanation:
5x + 2x + 3x = 180 (all angles in a triangle add up to 180)
10x = 180
x = 18°
∠L = 3x
sub x = 18
3(18) = 54

This is a math story ok omar is making a scale model of the statue of liberty the statue is 305 feet tall mesuring from the ground to the tip of the tourch if the model is 1/100 the acual size of the statue of liberty how tall is the model plz help i have 2 fss and i need to get my grades up
Answer:
[tex]Size= 3.05ft[/tex]
Step-by-step explanation:
Given
[tex]Scale = \frac{1}{100}[/tex]
[tex]Statue = 305ft[/tex]
Required
Determine the size of the statue
Size is calculated as thus:
[tex]Size = Scale * Statue[/tex]
[tex]Size = \frac{1}{100} * 305ft[/tex]
[tex]Size = \frac{305ft}{100}[/tex]
[tex]Size= 3.05ft[/tex]
Samuel needs 332 feet of wood to build a fence. The wood comes in lengths of 15 feet.
How many total pieces of wood will Samuel need? Theresa needs twice as many feet of wood as Samuel. How many pieces of wood does Theresa need?
Answer:
23 and 45
Step-by-step explanation:
This is really just a simple division question. All we have to do to solve the first half is divide 332 by 15:
[tex]332 / 15 = 22.133333333[/tex]
We'll want to round that up to 23, because it seems they're asking for integers here.
For the next part of the question, all we have to do is double the result of the last operation and round that number up as well:
[tex]22.13333333 *2 = 44.2666667[/tex]
Which rounded gives us 45.
Hope this helps!
Answer:
Samuel will need 23 pieces of wood.
Theresa will need 46 pieces of wood.
Step-by-step explanation:
To find how many total pieces Samuel will need, we have to divide 332 feet into 15, since each piece of wood is equivalent to 15 feet:
[tex]332[/tex] ÷ [tex]15=22.1333[/tex]
Samuel can't have a portion of wood, the wood pieces he has must be represented as a whole number. We have to round up to 23 pieces of wood.
Samuel will need 23 pieces of wood to build his fence.
_
If Theresa needs twice as many feet as wood, we have to multiply Samuel's pieces of wood by its length (15 feet):
[tex]23[/tex] × [tex]15=345[/tex]
Multiply [tex]345[/tex] by 2:
[tex]345[/tex] × [tex]2=690[/tex]
Now, divide [tex]690[/tex] by [tex]15[/tex]:
[tex]690[/tex] ÷ [tex]15[/tex]
[tex]=46[/tex]
Theresa will need 46 pieces of wood.
A triangle has rotation symmetry that can take any of its vertices to any of its other vertices. Select ALL conclusions that we can reach this.
A. All sides of the triangle have the same length
B. All angles of the triangle has the same measure
C. All rotations take one half of the triangle to the other half of the triangle
D, it is a right triangle
E. None of the sides of the triangle have the same length
F. None of the angles of the triangle have the same measure
Answer:
c e f
Step-by-step explanation:
C. All rotations take one half of the triangle to the other half of the triangle
E. None of the sides of the triangle have the same length
F. None of the angles of the triangle have the same measure
If a shape has a rotation symmetry, then the shape will look exactly the same after rotation. The conclusions to reach for a triangle that has a rotation symmetry are:
A. All sides of the triangle have the same length
B. All angles of the triangle has the same measure
Of all kinds of triangle, only an equilateral triangle has a rotational symmetry.
This means that:
All sides of the triangle must be the sameAll angles of the triangle must be the sameThe complete length of each side are rotated (not half).The above points imply that: options (a) and (b) are true
See attachment for an illustration of rotation symmetry of a triangle.

Answer:
C, 5/2
Step-by-step explanation:
3 I2x -1I + 4 = 16
Isolate absolute value:
3 I2x -1I + 4 - 4 = 16 - 4
3 I2x -1I= 12
(3 I2x -1I) / 3 = 12 / 3
I2x -1I= 4
Since the question is only asking for the positive, all you need to solve for is the +4. Solve for x
2x -1 = 4
2x -1 + 1 = 4 +1
2x = 5
2x / 2 = 5 / 2
x = 5/2 or C

Solve the equation for a
5n + 34 = -2(1 - 7n)
a equals
Answer:
n = 4
Step-by-step explanation:
Where's a or did you mean n?
Answer:
n=4
Step-by-step explanation:
5n+34=-2(1-7n)
1. So first expand.
5n+34=−2+14n
2 Regroup terms.
5n+34=14n−2
3 Subtract 5n from both sides.
34=14n−2−5n
4 Simplify 14n-2-5n to 9n-2.
34=9n−2
5 Add 22 to both sides.
34+2=9n
6 Simplify 34+2 to 36.
36=9n
7 Divide both sides by 9.
36/9=9
8 Simplify 36/9 to 4
4=n
9 Switch sides.
n=4

Which of the following is the sum of all the odd integers between 5 and 102?
A. 2592
B. 2597
C. 2601
D. 2603
Answer:
2601
Step-by-step explanation:
The integers between 5 and 102 are
7, 9, 11, 13, 15, 17,19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101
The sum of the odd intergers between 2 and 105 can be calculated as follows
= (N + 1/2)^2
= (101 + 1 /2) ^2
= (102/2)^2
= 51^2
= 2601
Hence the sum of the odd intergers between 5 and 102 is 2601
The amount of memory available on an iPhone seems like it doubles with each new version. If this is true, and the first version had 4 gigabytes of memory, how much memory does the 10th version have?
Answer:
40
Step-by-step explanation:
Multiply 10 by 4 which 4 represents the starting Iphone memory storage and then 10 represents the value of memory for the 10th model.
By solving the exponent, we find that the 10th version will have 2048 gigabytes of memory.
What are exponents?An exponent is a number that is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.

Answer:
Potential Energy = 10J
Step-by-step explanation:
mass of the book = 1.0kg
height = (0.5 + 1)m

answer and get 20 points
If two variables x and y are directly proportional, then as x rises, y will rise accordingly, and as x falls, y will fall accordingly. So, y=k x can be written.
The equation for k=y/x is k=b/p.
What exactly is a constant proportion?the proportional relationship between two variables that is always constant.
Constant ratio, constant rate, constant of variation, or even changing rate are examples of proportionality constants.
Describe continuous rate.When the ratio of the output to the input remains constant at every given point along the function, the rate of change is said to be constant.
The slope is another name for the constant rate of change.
The rate of change for linear functions will be constant.
