The lengths of the sides of a triangle are in the extended ratio 4:7:10. The perimeter of the triangle is 105 cm. What are the lengths of the sides?
=========================================================
Explanation:
The sides are in the ratio 4:7:10
This scales up to 4x:7x:10x showing that the sides are 4x, 7x and 10x. The variable x is some positive real number.
Add up the sides and set this equal to the given perimeter 105. Solve for x.
4x+7x+10x = 105
21x = 105
x = 105/21
x = 5
This value is then plugged into each side
4x = 4*5 = 207x = 7*5 = 3510x = 10*5 = 50The triangle has sides of 20 cm, 35 cm, and 50 cm.
Note how the ratio 20:35:50 reduces to 4:7:10 after dividing all three parts by the GCF 5. Also, we can see that 20+35+50 = 105 to fully confirm our answer.

Answer:
4.5 units
Step-by-step explanation:
PQ transferred to WX, and QR to XY.
PQ = 4, WX = 6, so the scaling factor x applies so that we create 6 or of 4 :
4 × x = 6
x = 6/4 = 3/2
the save scaling factor applies now to all other sides too due to the fact that the same transformation was done to the whole shape.
=> QR × 3/2 = XY.
3 × 3/2 = 9/2 = 4.5 = XY

A sequence has three terms.
Its term-to-term rule is
multiply by 6 and then add 13
a) The first term of the sequence is -2
Work out the third term.
b) The order of the three terms of the sequence is reversed.
Describe the term-to-term rule of the new sequence.
Submit Answer
Answer:
It's C
Step-by-step explanation: I took the test and got it wrong
The third term of the given sequence exists 19.
Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex] is reversed will be [tex]$\frac{a-13}{6}$[/tex].
What is a sequence?The sequence exists in a particular order in which connected things follow each other.
The term-to-term rule of the sequence stands 6a+13, where a stands for the first term First-term a = -2
Second term b will be [tex]$-2*6+13=1$[/tex]
The rule for the third term will be 6b+13, where b will be the second term. So the third term will be [tex]$6* 1+13=19$[/tex]
So, the sequence will be [tex]$-2,1,19 \ldots \ldots . .$[/tex]
If the order of the above sequence stands reversed, the new sequence will be [tex]$19,1,-2 \ldots \ldots .$[/tex]
If we subtract 13 from first term 19 and then divide by 6 we will get 1 which stands for the second term of the new sequence [tex]$19,1,-2 \ldots \ldots .$[/tex]
So a new term-to-term sequence rule will be [tex]$\frac{a-13}{6}$[/tex] where a stands for the first term.
Therefore, the third term of the given sequence exists 19.
Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex] exists reversed will be [tex]$\frac{a-13}{6}$[/tex].

what is the degree of the simplest polynomial with integer coefficients that has √2 , 2 , √2 + i , and 2 + 2i as some of its zeros?
a. 6
b. 7
c. 8
d. 9
If the polynomial has integer coefficients, then any complex roots with non-zero imaginary part must occur along with their conjugates. If a + bi is a root, then so is a - bi.
The given polynomial would then have at least 6 roots: √2, 2, √2 + i and √2 - i, and 2 + 2i and 2 - 2i. So the minimum degree is (A) 6.

Which of the following shows that the sum of two irrational numbers can be irrational?
A. (5+π)+(3-π)
B. √3+√5
C. (3+√5)+(3-√5)
D. (π/3)+(-π/3)
help?
Given:
The sum of irrational number in the options.
To find:
The option that shows the sum of two irrational numbers can be irrational.
Solution:
In option A,
[tex](5+\pi)+(3-\pi)=5+\pi+3-\pi[/tex]
[tex](5+\pi)+(3-\pi)=5+3[/tex]
[tex](5+\pi)+(3-\pi)=8[/tex]
We know that 8 is a rational number. So, option A is incorrect.
In option B,
[tex]\sqrt{3}+\sqrt{5}[/tex]
Here both numbers are irrational and it cannot be simplified further.
So, [tex]\sqrt{3}+\sqrt{5}[/tex] is an irrational number and option B is correct.
In option C,
[tex](3+\sqrt{5})+(3-\sqrt{5})=3+\sqrt{5}+3-\sqrt{5}[/tex]
[tex](3+\sqrt{5})+(3-\sqrt{5})=3+3[/tex]
[tex](3+\sqrt{5})+(3-\sqrt{5})=6[/tex]
We know that 6 is a rational number. So, option C is incorrect.
In option D,
[tex](\dfrac{\pi}{3})+(-\dfrac{\pi}{3})=\dfrac{\pi}{3}-\dfrac{\pi}{3}[/tex]
[tex](\dfrac{\pi}{3})+(-\dfrac{\pi}{3})=0[/tex]
We know that 0 is a rational number. So, option D is incorrect.
Therefore, the correct option is B.

Answer:
a = 8,059.52 m²
Step-by-step explanation:
Area of square
a = s²
a = 56²
a = 3,136
--------------------
Area of circle
a = πr²
a = 3.14(56/2)²
a = 2,461.76
Area of 4 semicircles = area of 2 circles
a = 2,461.76 * 2
a = 4,923.52
-----------------------
Total area
a = 3,136 + 4,923.52
a = 8,059.52 m²

Write in standard form the equation of a line with a slope of -3/5 and a y intercept of -3
Answer:
5y+3x=-9
Step-by-step explanation:
Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the slope-intercept form of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.
From this problem, we are given both the slope and the y intercept. We know have the equation:
[tex]y=-\frac{3}{5}x -3[/tex]
Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.
[tex]y+\frac{3}{5} x=-3[/tex]
This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.
[tex]5y+3x=-9[/tex]
I hope this helps! Please let me know if you have any questions :)
Work out the equation of the line that is parallel to the line y = 5x - 3 but also passes through (-2, -4).
Answer:
[tex]y = 5x + 6[/tex]
Step-by-step explanation:
Parallel lines have the same slope
→ Since the equation is [tex]y = 5x - 3[/tex] and the form of a linear equation is [tex]y = mx + b[/tex], with [tex]m[/tex] being the slope, therefore 5 is the slope
Which creates the equation this far:
[tex]y = 5x + b[/tex]
→ Now, substitute the values of the point (-2, -4) into equation [tex]y = 5x + b[/tex]
[tex](-4) = 5(-2) + b[/tex]
→ Solve for [tex]b[/tex]
[tex]-4 = -10 + b\\-4 + 10 = b\\6 = b[/tex]
Resulting in the equation :
[tex]y = 5x + 6[/tex]

A closed container has 2.04 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
0.34 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068 ⋅ 10−1
0.37 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71 ⋅ 10−1
3.41 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068
3.71 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71
Answer: 0.34 grams
Step-by-step explanation:
Given:
Number of atoms in a closed container
Weight of one atom
Total mass of all the atoms of the gas in the container

Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees
