Literally have no clue how to do the heart beat please help
Step-by-step explanation:
To find the rate, divide the number of heartbeats by the number of seconds.
You: 22 beats / 20 seconds = 1.1 beats per second.
Friend: 18 beats / 15 seconds = 1.2 beats per second.
A cone has height h and a base with radius r. You want to change the cone so its
volume is halved. What is the new height if you only change the height? What is the
new radius if you only change the radius? Explain.
9514 1404 393
Answer:
a) h/2
b) r/√2 = (r√2)/2
Step-by-step explanation:
a) The volume of a cone is proportional to height. If the volume is halved, then the height will be halved.
The new height will be h/2.
__
b) The volume is proportional to the square of the radius. If the volume is halved, the square of the radius is halved. The new radius will be ...
(r')² = r²/2
r' = r/√2 = (r√2)/2 . . . radius of half-volume cone

Answer:
C. 36 degrees
Step-by-step explanation:
Exterior angles sum = 360 degrees
72+144=216
360-216=144
Supplementary angles(Angles on opposite sides of the transversal) sum = 180
180-144= 36
Therefore, x=36 degrees

Step-by-step explanation:
each 20m miles takes 1g gallon.
Answer:
[tex]y=-\frac{1}{20} x + 20[/tex]
Step-by-step explanation:
The slope equation is always [tex]\frac{rise}{run}[/tex]. In this case, the gallons went down by 1- so we can call the rise -1. When it went down by 1, the miles went up by 20- so we can call the run 20. This gives us a fraction (the "m" value) to put in the slope equation [tex]y=mx+b[/tex]. To find the y intercept (the "b" value), you find out what y is when x = 0, which is given in the chart: 20.

An architect makes 14455.32 a year. If they get paid weekly, how much do they get each paycheck? Round to the nearest cent
Answer: $277.99
Step-by-step explanation:
There are 52 weeks in a year. Assuming the architect would get paid every week, you would divide their salary by 52.
14,455.32/52 = 277.9869
Rounding to two decimal places, the answer would be $277.99.
Answer:
301.15
Step-by-step explanation:

6^-6/6^-5 in the form 6^n
Answer:
6⁻¹
Step-by-step explanation:
6⁻⁶ = [tex]\frac{1}{6^6}[/tex] and 6⁻⁵ = [tex]\frac{1}{6^5}[/tex]
[tex]\frac{1}{6^6} * \frac{6^5}{1} = \frac{6^5}{6^6} = \frac{6^0}{6^1} = \frac{1}{6}[/tex] ** top & bottom same base 6, subtract exponent
[tex]\frac{1}{6}[/tex] = 6⁻¹

A farmer has a rectangular plot of land. There is a bother identical plot of land 100 yards east and 100 yards north. Find the combined area of the two plots of land
Answer:
Step-by-step explanation:
Area of a rectangular plot = Length × width
With the aid of the diagram attached below.
For plot 1:
The area = ( 60 - 20 ) × ( 80 - 20 )
Area = 40 × 60
Area = 2400 sq yard
For plot 2:
Area = (160 - 120 ) × ( 180 - 120 )
Area = 40 × 60
Area = 2400 sq yard
Therefore, the combined area of the two plots of land = 2400 + 2400
= 4800 square yards

Note: Your equation seems a little unclear. But, I am assuming that your equation is:
[tex]e^x\:+\:e^{-1}=\:2[/tex]
Because my solution would still clear your concept about this topic, no matter what the question is.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]e^x\:+\:e^{-1}=\:2[/tex]
subtract [tex]e^{-1}[/tex] from both sides
[tex]e^x+e^{-1}-e^{-1}=2-e^{-1}[/tex]
[tex]e^x=2-\frac{1}{e}[/tex]
[tex]\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)[/tex]
[tex]\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)[/tex]
[tex]\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)[/tex] ∵ [tex]\:\:\ln \left(e\right)=1[/tex]
[tex]x=\ln \:\left(2-\frac{1}{e}\right)[/tex]
[tex]x=0.5[/tex]

16. In the figure below, vertices D and F of ADEF lie on
CG, the measure of ZCDE is 148°, and the measure of
ZEFG is 140°. What is the measure of ZDEF?
E
?
140°
148°
D
C
F 720
G. 989
H. 100°
J. 108°
K. 116°
Answer:
J. 108°
Step-by-step explanation:
m<EDF = 180 - 148 = 32° (angles on a straight)
m<EFD = 180 - 140 = 40°(Angles in a straight line)
m<DEF = 180 - (m<EDF + m<EFD) (sum of triangle)
m<DEF = 180 - (32 + 40)
m<DEF = 180 - 72
m<DEF = 108°

Which inequality has the graph shown below?
Answers above ^
Answer:
The inequality the graph has shown is y < 2x - 3 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptFrom the given figure
∵ The line drawn is a dashed line
→ That means the sign of inequality without the equal sign
∴ The sign of the inequality is without the equal sign
∵ The shaded area is under the line
→ That means the sign of the inequality is smaller than
∴ The sign of the inequality is <
∵ The line intersects the y-axis at point (0, -3)
→ That means the y-intercept is -3
∴ The y-intercept = -3 ⇒ (value of b in the equation of the line)
∵ There is only one answer has sigh < and y-intercept -3
∴ The inequality the graph has shown is y < 2x - 3
Wes had 4.75 in quarters and dimes if he had 25 coins how many of each did he have?
Answer:it would be 15 quarters and 10 dimes
Step-by-step explanation:
15 quarters is 3.75 and 10 dimes is $1, add them up you get $ 4.75
Answer:
15 quarters and 10 dimes
Step-by-step explanation:
25x + 10(25-x) = 475
x = 225/15
x = 15
So that has to mean he has 10 dimes

Step-by-step explanation:
Use the equation i = prt (interest = principle*rate*time):
Principle: $900
Rate: 0.06 (6%)
Time: 2 years
Put it all in an equation:
i = 900*0.06*2
i = $108

- A rational number is a terminating or repeating decimal.
- An irrational number is when you can't write that number as a fraction.
Rational or Irrational: [tex]33[/tex]% = Rational number. ([tex]33[/tex]% = [tex]0.33[/tex], This is a terminating decimal.)[tex]\frac{1}{3}[/tex] = Rational number. ([tex]\frac{1}{3}[/tex] = [tex]0.3[/tex], This is a repeating decimal.)[tex]\frac{5}{3}[/tex] = Rational number. ([tex]\frac{5}{3}[/tex] = [tex]1.6[/tex], This is a repeating decimal.) [tex]\frac{}{.6}[/tex] = Irrational number. (You can't turn this into a true fraction, therefore it's irrational.)______________________________

what is the slope (5,7) and (2,-2)
Answer:
slope = 3
Step-by-step explanation:
to find the slope you do (y2-y1)/(x2-x1)=m
so we can plug the points into this formula
(5,7) (2,-2)
x1 y1 x2 y2
-2-7/2-5=m
-9/-3=m
Simplifies to
3=m
