Answer:
11/18
Step-by-step explanation:
1 2 + 1 9 = ? The Least Common Multiple (LCM) of 2 and 9 is 18. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM: 1 2 + 1 9 = 1 × 9 2 × 9 + 1 × 2 9 × 2 = 9 18 + 2 18 Now that the fractions have like denominators, add the numerators: 9 18 + 2 18 = 9 + 2 18 = 11 18 The result is: 1 2 + 1 9 = 11 18
so 11/18 is you answer
Answer:
11/18
Step-by-step explanation:
Get the common denominator by multiplying 2 and 9.
Multiply both sides of 1/2 by 9 to get 9/18, and both sides of 1/9 by 2 to get 2/18.
[tex]\frac{1}{2} +\frac{1}{9} = \frac{9}{18} + \frac{2}{18} = \frac{11}{18}[/tex]
After adding both fractions you'll get 11/18. That's your answer.
Suppose an earthquake can be felt up to 80 miles from its epicenter. You are located at a point 60 miles west and 45 miles south of the epicenter. Do you feel the earthquake? If so, how many miles south would you have to travel to be out of the range of the earthquake?
Answer:
Yes (you are 75 mi from epicenter). Travel at least 7.91 mi south
Step-by-step explanation:
See the attached image.
The epicenter is the point at the upper right of the drawing. You are 60 miles west (left) and 45 miles south (down) from the epicenter. A right triangle is formed--apply the Pythagorean Theorem, (leg)^2 + (leg)^2 = (hypotenuse)^2.
[tex]x^2=60^2+45^2\\\\x^2=3600+2025\\\\x^2=5625\\\\x=\sqrt{5625}=75[/tex] This is within 80 mi, so you feel the quake.
Now (see image2) you go y miles south. You want the distance between you and the epicenter to be at least 80 mi. You have another right triangle with legs 60 and y + 45 and hypotenuse 80.
[tex](y+45)^2+60^2=80^2\\\\(y+45)^2+3600=6400\\\\(y+45)^2=2800\\\\y+45=\sqrt{2800}\\\\y=\sqrt{2800}-45 \approx 7.91 \rm mi[/tex]

Answer:
point (-12, -5)slope 1/2Step-by-step explanation:
Compare the given equation to ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
You find that k = -5, m = 1/2, h = -12.
The point is (h, k) = (-12, 5). The slope is m = 1/2.
Skyler goes
to a school which has 1000 students in it.
She asks 40 random students whether they like the new 8.30 am start to the day.
30 of them say 'no' they do not like it.
Use this information to estimate how many students in the whole school
dislike the 8.30 am start.
Answer:
750
Step-by-step explanation:
30/40 students dislike it from the sample, so 0.75
1000 x 0.75 = 750
48% of student in a school are girls. a student is picked at random.what is the probability that a boy is picked
Answer:
0.52
Step-by-step explanation:
From the above question:
48% of students in a school are girls.
Let the total percentage of students = 100%
The percentage representing boys = 100% - 48% = 52%
Hence, the probability that a boy is picked = P(boy) = Percentage of boys/ Total percentage
P(boy) = 52%/100%
= 0.52/1
= 0.52
Therefore, the probability that a boy is picked is 0.52
Find the midpoint between these points.
(1,3) (5.1)
someone please help asap !!!
Answer:SOLUTION
The midpoint for two points P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2).
We have that px=1, py=3, qx=5, qy=1.
Thus, M=(1+52,3+12)=(3,2).
ANSWER
M=(3,2)A
Step-by-step explanation:
Answer:
The midpoint is (3, 2)
Step-by-step explanation:
To find the x-coordinate of the midpoint, average the x-coordinates 1 and 5:
1 + 5
xm = ----------- = 3
2
y-coordinate:
1 + 3
ym = ----------- = 2

The midpoint is (3, 2)
Find the area of the kite.
6
2
10
16
A=
square units
Answer:
72
Step-by-step explanation:
The area of a kite is half the product (multiplication) of the diagonals.
Each diagonal has length 12, so A = (1/2)(12)(12) = (1/2)(144) = 72.
Note: You can also find the area by finding the areas of the 4 right triangles. By the way, the diagonals are perpendicular, so all 4 triangles are right triangles.
Area of a small triangle: Area = (1/2)(base)(height) A = (1/2)(2)(6) = 6.
Area of a larger triangle: A = (1/2)(10)(6) = 30
Total area: 2 small triangles plus 2 larger triangles A = 2(6) + 2(30) = 72
The circumference of a circle is 56.52 feet. What is the circle's radius?
C=56.52 ft
Use 3.14 for .
Answer:
If we substitute pi as 3.14 we would be doing -
56.52/3.14 = 18
18/2 = 9.
So the circle's radius would be 9.
BUT if you want it with PI. . .
The answer would be 8.995437385

Which ordered pair is a solution to the equation?
y=x54−3
(−5, −7)
(5, −1)
(10, −11)
(−10, 5)
Answer:
y=4/5x-3 - (-5, -7)
Step-by-step explanation:
So to solve this, lets just plug in each value for x, and see if the y value we get is equal to one of our answers.
So we have (-10, 5)
Well plug in -10 for 4/5x we get:
-40/5=-8
Next we take that value and solve:
y=-8-3
y=-11
The answer for this was 5, not -11.
Ill skip a few steps:
(10, -11):
Plug in 10 we get:
y=8-3 which is y=5. This is not right, for it needed to be -11.
Next we have (5, -1)
This gets us y=4-3 this is y=1 which is not -1. So thats not right.
Finally we have (-5, -7):
This gets us y=-4-3 this is y=-7. What was our y value? -7!
So the answer is (-5, -7)
I hope this helps! :)

Step-by-step explanation:
we would like to simplify the following expression:
[tex] \displaystyle (2 + 2) + (4 - 1)[/tex]
in order to do we can consider the order of PEMDAS which is the abbreviation of Parentheses, Exponent, Multiplication,or Division, Addition or substraction
since Parentheses come first we'll simplify parentheses:

You accumulated a balance of $2,300 on your credit card that carries an interest rate of 17%. You can't afford to pay the $2,300 all at once, but you can pay the minimum payment, which is 2% per month or $25, whichever is greater. What is the balance on your card after 5 years?
Answer:
$1,591.67
Step-by-step explanation:
The computation of the balance after 5 years is shown below:
Given that
Accumulated Balance on Credit Card = P = $2,300
r = Monthly interest amount = 17% ÷ 12 = 1.41666667%
M = Minimum payment = 2%
Now
Balance on Credit Card after t year = P × (1+r) ×(1-M)
= $2,300 × (1+1.41666667%)^t × (1 - 2%)^t
= $2,300 × (0.993883337)^t
SO,
Balance on Credit Card after 5 years is
= $2,300 × (0.993883337)^60
= $2,300 × 0.692029437
= $1,591.66771
= $1,591.67

The total surface area of a cube is 294 cm".
Work out the volume of the cube.
i would really appreciate it thank you!! :)
Hey Buddy,
Answer:
343 cm³
Step-by-step explanation:
Total Surface Area of the cube = 294 cm²
Surface Area = 6a²
6a² = 294
a² = 49
a = square root of 49
= 7
Volume of a cube = a³
Thus, the volume of the cube = 7³
= 7*7*7
= 343 cubic centimeters

Answer:
d = 46.15
A = 1672.76
Hope this helps!
Answer:
Diameter = 46.18 inches
Area = 1,674.09 square inches
Step-by-step explanation:
Circumference = pi x diameter
145 = 3.14d
divide both sides by 3.14
d = 46.1783 inches
------------------------
radius = 1/2 x diameter
r = 23.09
Area = (pi)(r)^2
A = (3.14)(23.09)(23.09)
A = 1,674.09 square inches
