Answer:
13.60units
Step-by-step explanation:
Given data
U(-7,5) and V(4, -3)
x1=-7
y1=5
x2= 4
y2= -3
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((4-(-7))²+(-3-5)²)
d=√((4+7))²+(-8)²)
d=√(11)²+(-8)²)
d=√121+64
d=√185
d=13.60units
Hence the distance is 13.60units
Mrs. Smith paid $125 to have her hair colored and cut. If she tips her hairdresser 15% of her bill, how much was the tip? (pls include the steps)
Answer:
$18.75
Step-by-step explanation:
15% = 15/100
125 × 15/100
=1875/100
=18.75
which two ratios represent quantities that are proportional help i will mark as brainless
Answer:
A
Step-by-step explanation:
So, lets take all of our ratios, and simplfy them the best we can. Once we do this, we can easily compare and see which ratios are and are not similar.
So lets start with A:
21/28 and 12/16
Lets simplfy each fraction.
The greatest number that goes into the numeraotr and denominator(GCF) of 21/27 is 7. Taking out 7 we get:
3/4
We can do the same with the 12/16. 4 goes into both the numerator and denominator:
3/4
So this would work.
Lets look at the others, and see if any others work as well:
56/64 and 36/48
8 goes into both 56 and 64:
7/8
4 goes into 36 and 48:
9/12
These are clearly different.
Next we have 9/10 and 10/9
We can instantly see that one is bigger than 1, and the other is smaller than 1, so they must be different.
Finally we have 5/7 and 7/14
Again, these are clearly different.
If we give both the same denominator, which can be 14, we get:
10/14 and 7/14
We get 10/14 from 5/7 since we need to multiply both numerator and denominator by 2 so that the 7 becomes 14 in the denominator.
10/14 adn 7/14 are clearly different, so these dont work as well.
Only A, which is 21/28 and 12/16, will work.
Hope this helps!
Find the expression different from the others. Do this by showing that the other four are equivalent to each other using the properties of exponents. (4 points)
A)2^4x+2
B)4•16^x
C)2+4^4x
D)2^2 • 4^x (over) 4^-x
E)4^2x+1
Answer:
C) 2+4^4x
Step-by-step explanation:
A) 2^(4x+2) = 2^4x • 2² = 16^x • 4
B) 4 • 16^x = 16^x • 4 (already done)
D) 2^2 • 4^x (over) 4^-x
= 4 • 4^x • 4^x = 16^x • 4
E) 4^(2x+1) = 4^2x • 4¹ = 16^x • 4
What is the area of the triangle?
Answer:
A = 48 in²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 24 and h = 4 , then
A = [tex]\frac{1}{2}[/tex] × 24 × 4 = 12 × 4 = 48 in²
Answer:
A = 48 in.^2
Step-by-step explanation:
Area of triangle = (Base * height) / 2
Area of triangle = (24*4)/2
Area of triangle = 48 in.^2

The perimeter of a rectangle is 32 inches. The length is 1 foot. What is the width of the rectangle in inches? A. 4 inches B. 10 inches C. 15 inches D. 20 inches 12 / 15
Answer:
A. 4 inches
Step-by-step explanation:
Applying,
P = 2(L+W)............. Equation 1
Where P = Perimter of the rectangle, L = Length of the rectangle, W = width of the rectangle.
make W the subject of the equation
W = (P/2)-L............ Equation 2
From the question,
Given: P = 32 inches, L = 1 foot (Convert from Foot to inches), L = 12 inches
Substitute these values into equation 2
W = (32/2)-12
W = 16-12
W = 4 inches.
Hence the right option is A.
A triangle has sides with lengths of 8 centimeters, 15 centimeters, and 17 centimeters. Is it a right triangle?
Answer:
Yes it is!
Step-by-step explanation:
If you want to know whether it is, use the pytheoream theory. a2+b2=c2
a is the shortest side, b is the second longest and c is the longest.
In this case, the equation will be:
8 sq + 15 sq = 17 sq
64 + 225 = 289
= It is a right-angled triangle!
What's the area of these two shapes please explain!
Answer:
Figure 1 is 50 cm. Figure 2 is 225 mm.

4n + 2 = 6 (1/3n-2/3)
N=???
l give brainiest
Answer:
N= -3
Step-by-step explanation:
4n+2 = 6(1/3n - 2/3)
4n+2 = 2n - 4
2n +2 = -4
2n = -6
n = -3
Answer:
- 3
Step-by-step explanation:
4n + 2 = 6 ( 1 / 3 n - 2 / 3 )
Divide 2 on both sides,
2n + 1 = 3 ( 1 / 3 n - 2 / 3 )
2n + 1 = 3n / 3 - 6 /3
2n + 1 = n - 2
2n - n = - 2 - 1
n = - 3

ab - 0.5b when a = 1 and b = 5
Answer:
2.5
Step-by-step explanation:
a = 1
b = 5
ab
= 1 x 5
= 5
0.5b
= 0.5 x 5
= 2.5
ab - 0.5b
= 5 - 2.5
= 2.5
Answer:
2.5
Step-by-step explanation:
ab - 0.5b
a = 1 and b = 5
(1)(5) - 0.5(5)
Multiply (1)(5) = 5
5 - 0.5(5)
Multiply -0.5(5) = -2.5
5 - 2.5
Subtract 5 - 2.5 = 2.5
2.5

Examine the pattern below and give the next three terms in the sequence.the pattern 1,3,4,7,11,18,29
Answer:
47, 76, 123
Step-by-step explanation:
Fibonacci Sequence
Answer:
47 , 76 , 123
Step-by-step explanation:
3rd term = 1st term + 2nd term = 1 + 3 = 4
4th term = 2nd term + 3rd term = 3 + 4 = 7
Next three terms:
8th term = 18 +29 = 47
9th term = 29 + 47 = 76
10th term = 47 + 76 = 123

66.21 was rounded to 2dp. what is the lower bound?
Answer:
the answer is 66.205
Step-by-step explanation:
basically you look at the place value so
66.21 is basically the same as 66.210 then you look at the lowest number that can round UP to 66.210 which would be out of 1 to 9 would be 5 so the smallest number that can round up to 66.210 is 66.205 hope this helped :D

Find the missing side length, and enter your answer in the box below. If necessary, round your answer to 2 decimal places. 2
Answer:
Length of missing side is 177.5
Step-by-step explanation:
sum of all angles of right triangle is 180 °
length of missing side = c1.5° + 2° + c = 180°
combine like terms
2.5 ° + c = 180°
Subtract 2.5 from each side
2.5 ° - 2.5° + c = 180° - 2.5°
c = 177.5
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.

Step-by-step explanation:
30 ≥ 5(6n) Choose the correct answer. n ≤ 2 or
n ≤ 1
Answer:
1 ≥ n
Step-by-step explanation:
30 ≥ 5(6n)
Distribute
30 ≥ 30n
Divide each side by 30
30/30 ≥ 30n/30
1 ≥ n
30 >= 5(6n)
Divide both sides. Y 5:
6 >= 6n
Divide both sides by 6:
1 >= n
Rewrite as: n ≤ 1
