Answer: 4.2
Step-by-step explanation:
Here's the formula for how to find the hypotenuse: (a and b are the two legs for the triangle-- it doesn't matter which leg is a and which leg is b, but c MUST be the hypotenuse)
[tex]a^2+b^2=c^2[/tex]
[tex]1.9^2+3.8^2=c^2[/tex]
[tex]3.61+14.44=c^2[/tex]
[tex]18.05=c^2[/tex]
[tex]\sqrt{18.05} =c[/tex]
[tex]c=4.2[/tex]
The product of two numbers is 41. One of the numbers
is the complex number 5+4i. What is the other
number?
A. 5-4i
B. 5+4i
C. -5-4i
D. -5+4i
E. 41/5-4i
===================================================
Work Shown:
x = the other number
(5+4i)*x = 41
x = 41/(5+4i)
x = 41*(5-4i)/( (5+4i)*(5-4i) ) ..... see note below
x = 41*(5-4i)/( 41 )
x = (41/41)*(5-4i)
x = 5 - 4i
As a way to check, (5+4i)*(5-4i) = 5^2+4^2 = 25+16 = 41
The rule used is (a-bi)(a+bi) = a^2 + b^2
-----------
Note: I multiplied top and bottom by (5-4i) to get rid of the imaginary term in the denominator.
In A Quiz Team a Scores -30 , 10 , 40 .
Team B scores 30 , 10 , -10 In Three Rounds.
Which Team Scored More . By How much
Answer:
Team B scored more. By 10.
(Team A) -30 + 10 = -20 + 40 = 20
(Team B) 30 + 10 = 40 + -10 = 30

Find the equationFind the equation (in terms of
x
) of the line through the points (-4,-5) and (3,5) (in terms of x ) of the line through the points (-4,-5) and (3,5)
Answer:
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-4, 3)
Points on the y-axis (y1, y2) = (-5, 5)
To find the equation of line in terms of x;
First of all, we would determine the slope of the line;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {5 - (-5)}{3 - (-4)} [/tex]
[tex] Slope, m = \frac {10}{7} [/tex]
Slope, m = 10/7
Next, we find the equation;
y - y1 = m(x - x1)
y - (-5) = 10/7(x -(-4))
y + 5 = 10/7(x +4)

Help please! Much appreciated
Answer:
a. Sin B = 15/17
b. Cos B = 8/17
c. Tan B = 15/8
Step-by-step explanation:
Recall: SOHCAHTOA
Reference angle = B
Opp = 15
Adjacent = 8
Hypotenuse = 17
a. Sin B = Opp/Hyp (applying SOH)
Substitute
Sin B = 15/17
b. Cos B = Adj/Hyp
Substitute
Cos B = 8/17
c. Tan B = Opp/Adj
Substitute
Tan B = 15/8
Find the surface area of the regular pyramids. Round your answer to the nearest tenth.
Answer:
S.A = 147.35 cm²
Step-by-step explanation:
Surface area of the triangular pyramid = base area + ½(perimeter of base*slant height)
Base area = ½*bh
b = 7 cm
h = 6.1 cm
Base area = ½*7*6.1 = 21.35 cm²
Perimeter of triangular base = 7 + 7 + 7 = 21 cm
slant height = 12 cm
Plug in the values into the equation
S.A = 21.35 + ½(21*12)
S.A = 21.35 + 126
S.A = 147.35 cm²

What is the probability that a randomly selected person supports the new station??
Best answer gets brainliest!! Please help
Answer:
.52
Step-by-step explanation:
We can write an equation
supports/all
we can see that 27 males and 25 females support which means that
27+25= 52 total people support
now we just need to find the number of people surveyed
we do this by summing everything
27+25+18+13+5+12=100
52/100 = .52
Answer:
.52
Step-by-step explanation:
Add both male and female supports to get 52
then add all the numbers to get a total of 100
52/100=.52

Answer:
A. 29
B. 11
C. 10
D. 12
Step-by-step explanation:
A. 180 - 122 = 58
58 divided by 2 = 29
-
B. 180 - 37 = 143
x = 11
5 x 11 = 55
8 x 11 = 88
55 + 88 = 143 + 37 - 180

C. the small box in a triangle means right angle = 90
90 - 68 = 22
(2x - 2) we subtract before finding out what x is
22 - 2 = 20
2x = 20 divide by 2 = 10
x is equal to 10
-
D. to find the total, you must figure out what each equation is to add them up to make 180.
(8x + 3) + (2x + 9) + 4x = 180
add up the numbers with x and the numbers without them
14x + 12 = 180
subtract 180 - 12 = 168
168 divided by 14 = 12
x = 12

Answer:
3a/6b
Step-by-step explanation:
-5a/18b cannot be simplified. Therefore, 3a/6b and -5a/18b are not the same.
3a/6b can be simplified. Both the denominator and the numerator can be divided by 2. Therefore, the fraction will be a/2b. a/2b is equal to a/2b so 3a/6b is the correct answer.

A max subscription for Twitch, a streaming service, costs a flat fee of $25. You can then also buy small subscriptions for others for $5 per subscription. Johnny is trying to budget the amount of money he wants to spend.
Let y represent the total amount of money spent, and x represent the number of small subscriptions he purchases.
Answer:
y = 25 + 5x
Step-by-step explanation:
Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.

Answer:
A. 2 square feet
B. draw a diagonal; 1 square foot
Step-by-step explanation:
A. The area of a parallelogram is given by the formula ...
A = bh
Here the base (b) is 3 feet, and the height (h) is 2/3 ft. The area is ...
A = (3 ft)(2/3 ft) = 2 ft^2 . . . . area of the parallelogram
__
B. Drawing a diagonal (AC or BD) will divide the figure into two congruent triangles. Each triangle has the same base and height as the original parallelogram. The area of one of the triangles is given by ...
A = 1/2bh
Using the given dimensions, ...
A = 1/2(3 ft)(2/3 ft) = 1 ft^2 . . . . area of one triangle
