Answer:
3600 m or 3.6 km
Step-by-step explanation:
The first thing is to take into account that the pulse rate is equal to 75 per minute, or what is the same as 75 beats per 60 seconds, then we must know how many seconds would be 15 beats:
15 beats * 60 seconds / 75 beats = 12 seconds
Therefore, we know that the velocity is equal to:
v = d / t
We know the time and the speed, therefore:
d = v * t
replacing
d = 300 * 12
d = 3600
is located at 3600 meters or 3.6 km
express 0.029646 correct to three decimal places
Answer:
0.030
Step-by-step explanation:
=> 0.029646
To three dps that there should be only 3 decimals places after rounding off.
So, it becomes
=> 0.030 (Because the digit in ten thousandths place was greater than 5)
Answer:
0.03.
Step-by-step explanation:
The 3rd decimal place is 9 so we round up the second place to 3.

Answer:
[tex]\dfrac{78y}{18y}[/tex]
Step-by-step explanation:
Multiplying by 1 is the same as multiplying by a fraction with the same numerator and denominator.
[tex]\dfrac{13}{3}=\dfrac{13}{3}\times\dfrac{6y}{6y}=\boxed{\dfrac{78y}{18y}}[/tex]
Solve (y/4) +3 = 7
a) y = 40
b) y = 1
c)y = 25
d) y = 16
(Y/4) +3 = 7
Subtract 3 from both sides:
Y/4 = 4
Multiply both sides by 4
Y = 16
Answer:
Option D
Step-by-step explanation:
=> (y/4)+3 = 7
Subtracting 3 from both sides
=> y/4 = 7-3
=> y/4 = 4
Multiplying 4 to both sides
=> y = 4*4
=> y = 16

Given: ABCD ∥gram BK ⊥ AD , AB = 6, AK = 3 Find: m∠A, m∠B, m∠C, m∠D
Answer:
m∠A 60°, m∠B= 120°, m∠C =60°, m∠D=120°
Step-by-step explanation:
[tex] In\: ||^{gm} \: ABCD, \: BK\perp AD... (given) \\
\therefore \angle BKA = 90\degree \\
In\:\triangle BKA, \\\\
\cos \angle A = \frac{AK}{AB}\\\\
\cos \angle A = \frac{3}{6}\\\\
\cos \angle A = \frac{1}{2}\\\\
\cos \angle A = \cos 60\degree.. (\because \cos 60\degree = \frac{1}{2}) \\\\
\huge \red {\boxed {\therefore \angle A = 60\degree}} \\[/tex]
Since, adjacent angles of a parallelogram are Supplementary.
[tex] \therefore \angle A + \angle B = 180\degree \\
\therefore 60\degree + \angle B = 180\degree \\
\therefore \angle B = 180\degree - 60\degree\\
\huge \purple {\boxed {\therefore \angle B = 120\degree}} \\[/tex]
Since, opposite angles of a parallelogram are congruent.
[tex] \therefore \angle C = \angle A
\\
\huge \red{\boxed {\therefore \angle C = 60\degree}} \\\\
\therefore \angle D = \angle B
\\
\huge \purple {\boxed {\therefore \angle D = 120\degree}} \\[/tex]

Z^5=-7776i
Find the solution of the following equation whose argument is strictly between 270 and 360 degrees
Answer:
Z=+6
Step-by-step explanation:
Z^5=-7776i
Let's note that i I mathematics means negative one i.e
i = -1
So the equation is equal to
Z^5=-*-(7776)
Z^5 = 7776
Z= 5√7776
Since it's a divisible by 6
It's giving us a clue that 6 it's the answer.
Ok let's check the 5th root of 7776 in our calculator.
Z=+6
+6 is the solution to the equation

Solve #1 pls, I need to find the shortest side, median side, and longest side
Answer:
Shortest side = 39 cm.
Median side = 65 cm.
Longest side = 91 cm.
Step-by-step explanation:
The perimeter in total is 195 cm. The ratio of the sides are 3 : 5 : 7.
First, find how much parts there are as a whole, by combining the ratios:
3 + 5 + 7 = 15 parts.
Divide the total of parts from the total measurement:
195/15 = 13
Each part has the measurement of 13 cm.
1 part = 13 cm.
Use the following ratio to solve for each of the sides:
Shortest side: 3
3 x 13 = 39
Shortest side = 39 cm.
Median side: 5
5 x 13 = 65
Median side = 65 cm.
Longest side: 7
7 x 13 = 91
Longest side = 91 cm.
Check. Combine all side measurements together. They should equal 195:
39 + 65 + 91 = 195
(39 + 65) + 91 = 195
(104) + 91 = 195
195 = 195 (True).

What is the x-intercept of the following function?
h(x) = 4x+3 - 2
Answer:
Let h(x) = y
y = 4^(x+3) -2
For x intercept let y = 0
2 = 4^(x+3)
2= 2^2(x+3)
1 = 2x +6
2x = -5
2x = -5
Divide by 2
x = -5/2
The x intercept for the function is ( -5/2, 0)
Hope this helps.
Answer:
(-2.5,0)
Step-by-step explanation:
[tex]h(x)=4^{x+3}-2[/tex]
Since the x intercept of a graph is when the y value is 0:
[tex]0=4^{x+3}-2 \\\\2=4^{x+3} \\\\2=(2^2)^{x+3} \\\\2^1=2^{2x+6} \\\\1=2x+6 \\\\2x=-5 \\\\x=-2.5[/tex]
