Unit rate
Step-by-step explanation:
Rationalize the denominator of square root of negative 4 over open parentheses 7 minus 3 i close parentheses plus open parentheses 2 plus 5 i
Answer:
quantity of 16 plus 18 i over 145
Step-by-step explanation:
Answer:
sqrt(-49) / [ (7-2i) - (4+9i) ]
= 7i / (3 - 11i)
= 7i (3+11i) / [ (3 - 11i) (3 + 11i) ]
= (21 i - 77) / (9 + 121) = choice (d), (-77 + 21i) / 130

find the length of side X in simplest radical form with a rational denominator (giving brainliest and thanks to all!)
Answer:
x= √10/2
Step-by-step explanation:
if you use trig. functions:
sin 45° = opposite side /hypothenuse = x/√5
sin 45° = √2/ 2
√2/2 = x/√5 multiply both sides by √5
x= (√2*√5)/2 = √10/2
if you use that is a 45-45-90 special triangle
the sides are x, and hypothenuse must be x√2 in this type of triangles so in our case:
x√2 = √5 divide both sides by √2
x= √5/√2 multiply by √2/√2 which =1 and help us get rid of the radical from the denominator
x= (√5*√2)/ (√2*√2) = √10/2
Jimmy purchased a package of jelly beans that contained 75 jellybeans. Out of the 75 jellybeans, 8 are pink, 17 are orange, 22 are red, 18 are green, 6 are white and 4 are black.Jimmy later noticed that the package of jellybeans contained a hole and two jellybeans dropped out of the package while he was walking home.
Find completion to question in comment section.
Answer:
D. One of the jellybeans that slipped out was orange and one was black
Step-by-step explanation:
We calculate the option with the highest probability of occurrence :
Total number of jellybean = 75
n(T) =75
n(Pink) = 8
n(red) = 22
n(Orange) = 17
n(green) = 8
n(white) = 6
n(black) = 4
We assume that the jelly beans must have slipped out one after the other.
Evaluating the options :
A.)
P(pink) and P(white)
8/75 * 6/74 = 0.0086486
B.)
P(green) and P(green)
8/75 * 7/74 = 0.0100900
C.)
P(white) and P(white)
6/75 * 5/74 = 0.0054054
D.)
P(orange) and P(black)
17/75 * 4/74 = 0.0122522
From the probability values obtained, the highest is D. Hence, the most likely to have occurred is One of the jellybeans that slipped out was orange and one was black
The diameter of a circle is 24 miles. What is the circle's area?
d=24 mi
Use 3.14 for n.
square miles
Submit
Answer:
24÷2=12
3.14×12×12=452.16
Answer is 452.16
Answer:
The circle's area above is 452.39 I believe.
Step-by-step explanation:
Use A = pie*r^2 and d = 2 * r to solve this problem.
A = 1/4*pie*d^2 = 1/4*pie*24^2 = 452.38
Round and you have the area of the circle: 452.39

Convert the following equation into slope intercept form y-6=2(x+4)
Answer:
y = 2x +14
Step-by-step explanation:
We need to convert the given equation into slope intercept form ,
=> y - 6 = 2(x+4)
=> y -6= 2x + 8
=> y = 2x +8+6
=> y = 2x + 14

Find the circumference of the circle to the nearest hundredth
11cm
Question: Find the circumference of the circle to the nearest hundredth
d = 11cm
Answer:
34.54 cm
Step-by-step explanation:
Applying,
P = πd...................... Equation 1
Where P = Circumference of perimeter of the circle, d = diameter of the circle, π = pie
From the question
Given: d = 11 cm
Constant: π = 3.14
Substitute these values into equation 1
P = (3.14×11)
P = 34.54 cm

Step-by-step explanation:
i got a 100%
Answer:
A. y = 2x - 1
Step-by-step explanation:
First, find the slope. You can either use the rise/run method or use the slope formula, y2-y1/x2-x1. For the rise/run method, the rise is 4 and the run is 2, so... 4/2 = 2. If you want to use the slope formula, use the two coordinate sets, (1, 1) and (-1, -3). -3-1/-1-1 = -4/-2 = 2. Next, find your y-intercept. Use the slope-intercept formula, y = mx + b. M stands for the slope and b stands for your y-intercept. You can use either the coordinates (1, 1) or (-1, -3) to plug in for the x and y. In this scenario, I'll use (1, 1).y = mx + b
Plug in your values. (2 for m)
1 = 2(1) + b
Simplify.
1 = 2 + b
Subtract 2 from both sides.
-1 = b
Finally, form your equation together.
y = 2x - 1

Answer:
Volume of sphere A = 128x (Approx.)
Step-by-step explanation:
Given:
Radius of sphere A = 2 x Radius of sphere B
Volume of sphere B = 16x
Find:
Volume of sphere A
Computation:
Volume of sphere = (4/3)(π)(r)³
Volume of sphere B = (4/3)(π)(r)³
16x = (4/3)(π)(r)³
16x = (4/3)(22/7)(r)³
16x = (88/21)(r)³
Radius of sphere B = 1.56∛x Approx.
Radius of sphere A = 2 x Radius of sphere B
Radius of sphere A = 2 x 1.56∛x
Radius of sphere A = 3.12∛x Approx.
Volume of sphere A = (4/3)(π)(r)³
Volume of sphere A = (4/3)(22/7)(3.12∛x)³
Volume of sphere A = (88/21)(30.37∛x)
Volume of sphere A = 127.27x
Volume of sphere A = 128x (Approx.)
Find the area of the shaded region.
Round to the nearest tenth.
Answer:
The area of the shaded region is 11.606 square centimeters.
Step-by-step explanation:
The area of the shaded region is obtained by subtracting the area of the triangle from the area of the circular section. The area of the triangle ([tex]A_{t}[/tex]), in square centimeters, can be calculated by the Heron's formula:
[tex]A_{t} = \sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}[/tex] (1)
[tex]s = \frac{a + b + c}{2}[/tex] (2)
Where:
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Lengths of the sides of the triangle, in centimeters.
[tex]s[/tex] - Semiperimeter, in centimeters.
If we know that [tex]a = 10.50\,cm[/tex] and [tex]b = c = 9.28\,cm[/tex], then the area of the triangle is:
[tex]s = \frac{10.50\,cm + 2\cdot (9.28\,cm)}{2}[/tex]
[tex]s = 14.53\,cm[/tex]
[tex]A_{t} = \sqrt{(14.53\,cm)\cdot (14.53\,cm - 10.50\,cm)\cdot (14.53\,cm - 9.28\,cm)^{2}}[/tex]
[tex]A_{t} \approx 40.174\,cm^{2}[/tex]
And the area of the circular section ([tex]A_{c}[/tex]), in square centimeters, is determined by the following formula:
[tex]A_{c} = \left(\frac{\theta\cdot \pi}{360} \right)\cdot r^{2}[/tex] (3)
Where:
[tex]r[/tex] - Radius of the circle, in centimeters.
[tex]\theta[/tex] - Internal angle, in sexagesimal degrees.
If we know that [tex]r = 9.28\,cm[/tex] and [tex]\theta = 68.9^{\circ}[/tex], then the area of the circular section is:
[tex]A_{c} = \left(\frac{68.9}{360}\right)\cdot \pi\cdot (9.28\,cm)^{2}[/tex]
[tex]A_{c} \approx 51.780\,cm^{2}[/tex]
Finally, the area of the shaded region ([tex]A[/tex]), in square centimeters, is:
[tex]A = A_{c} - A_{t}[/tex] (4)
[tex]A = 51.780\,cm^{2}- 40.174\,cm^{2}[/tex]
[tex]A = 11.606\,cm^{2}[/tex]
The area of the shaded region is 11.606 square centimeters.

Step-by-step explanation:
*7. Admission to a museum is $8.20 per adult and $4.10 per child. The expression
8.2a + 4.1c represents the total cost in dollars for admission for a adults and a
children
A group of friends, consisting of 6 adults and 6 children attend the museum. One of
the adults has a coupon for one free adult admission and one child's admission at half
price. What is the total cost for the whole group to enter the museum?
Answer:
$63.55
Step-by-step explanation:
if one of the adults has a free coupon for adult admission, then we have 5 adults
8.20 x 5 = $41
We have 6 children and one with half pay
= (5 x 4.1) + (4.1/2 )
= 20.5 + 2.05
=$22.55
41 + 22.55 = $63.55

What is the measure of Zy?
139 yº
Answer:
y = 41°
Step-by-step explanation:
∡ y and 139° are adjacent angles and sum to 180° , that is
∠ 1 + 139° = 180° ( subtract 139° from both sides )
∠ 1 = 41°
a. Find the mean, median, and mode of 12, 9, 17, 15, 10.
mean:
median:
6
Answer:
Mean: 12.6
Median: 12
Mode: None
Step-by-step explanation:
To find the mode, add everything up.
12 + 9 + 17 +15 + 10 = 63. Then, divide by five.
63 ÷ 5 = 12.6
To find the median, put the numbers from least to greatest. Then, highlight the one in the middle.
9, 10, 12, 15, 17
To find the mode, look for the number that appears the most. Because each number appears once. So, put "none" in the box.
