Answer:
669ft high
Step-by-step explanation:
642+27=669ft
The height of the mountain is 669 ft.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
For example 4 -2 = 2
A drone takes off from the base of a mountain at a height of 27 ft below sea level.
To determine the height of the mountain.
Using the arithmetic operations of addition and subtraction,
The drone then flies up 642 ft before landing at the top of the mountain.
Assume that distance below sea level is positive,
So the height of the mountain as
⇒ 642 + 27
⇒ 669 ft
Hence, the height of the mountain is 669 ft.

A Ferris wheel at a carnival has a radius of 38 feet. Suppose a passenger is traveling at 5 miles per hour. (A usual fact: 1 mi = 5280 ft).A) Find the angular speed of the wheel in radians per minute.B) Find the number of revolutions the wheel makes per hour.
Answer:
a
[tex]w = 11.58 \ rad/minutes[/tex]
b
[tex]R_h = 111 \ revolution\ per \ hour[/tex]
Step-by-step explanation:
From the question we told that
The radius of the wheel is [tex]r = 38 \ ft[/tex]
The speed of the passenger is [tex]v = 5 \ miles /hr = \frac{26400}{3600} = 7.33 \ ft / s[/tex]
Generally the angular speed is mathematically represented as
[tex]w = \frac{v}{r}[/tex]
=> [tex]w = \frac{7.3}{ 38}[/tex]
=> [tex]w = 0.193 \ rad/s[/tex]
now converting the seconds to minutes
[tex]w = 0.193 *60[/tex]
[tex]w = 11.58 \ rad/minutes[/tex]
Generally number of revolutions the wheel makes per minutes is mathematically represented as
[tex]R = \frac{11.58 }{2 \pi}[/tex]
[tex]R = 1.84 \ rpm[/tex]
Generally number of revolutions the wheel makes per hour is mathematically represented as
[tex]R_h = R * 60[/tex]
=> [tex]R_h = 1.84 * 60[/tex]
=> [tex]R_h = 111 \ revolution\ per \ hour[/tex]

By substituting in the values of the variables, complete the addition number sentence that corresponds to the diagram below,
Answer:
[tex] a + b + c = 5 + 6 + 11 = 22 [/tex]
Step-by-step explanation:
Variable "a" and "b" represents distances on the numberline.
Variable "c" is the combined distance of the values of variable "a" and variable "b" on the numberline.
a = length of red line = |5 - 0| = |5| = 5
b = length of blue line = |11 - 5| = |6| = 6
c = length of black line (red+blue) = |11 - 0| = |11| = 11
Therefore:
[tex] a + b + c = 5 + 6 + 11 = 22 [/tex]

At the store, Jason find the volume of a soda pack is 423.9 in.³. If each cylinder shaped can has a height of 6 inches and a diameter of 3 inches, how many soda cans are in a pack? (Use 3.14 for pi)
Answer : The correct option is, (A) 10
Step-by-step explanation :
First we have to calculate the volume of cylinder shaped can.
Formula used:
Volume of cylinder = π r² h
where,
r = radius of cylinder
h = height of cylinder
Given:
Diameter of cylinder = 3 in
Height of cylinder = 6 in
Radius of cylinder = [tex]\frac{Diameter}{2}=\frac{3in}{2}=1.5in[/tex]
Now putting all the given values in the above formula.
Volume of cylinder = π r² h
Volume of cylinder = 3.14 × (1.5 in)² × 6 in
Volume of cylinder = 42.39 in³
Now we have to determine the number of soda cans are in a pack.
Number of soda cans are in a pack = [tex]\frac{\text{Volume of soda pack}}{\text{Volume of cylinder shaped can}}[/tex]
Number of soda cans are in a pack = [tex]\frac{423.9in^3}{42.39in^3}[/tex]
Number of soda cans are in a pack = 10
Therefore, the number of soda cans in a pack are 10.

Step-by-step explanation:
A nurse is preparing to administer dopamine 2 mcg/kg/min by continuous IV infusion for a client who weighs 110 lb. Available is dopamine
400 mg in 250 mL of D5W. The nurse should set the IV pump to deliver how many ml/hr administer? (Round the answer to the nearest
tenth.)
Answer:
3.7ml/hr
Step-by-step explanation:
From the question
A nurse is preparing to administer dopamine 2 mcg/kg/min by continuous IV infusion
Step 1
The patient weighs 110lb(pounds
Convert the patients weight to kilogram
1 lb = 0.454kg
110lb =
Cross Multiply
110lb × 0.454kg
= 49.94kg
The patient weight = 49.94kg
Step 2
The dosage to to be administered by the nurse = 2 mcg/kg/min
If 1 kg = to be administered 2mcg/min
49.94 kg =
(49.94kg × 2mcg/min)/1
= 99.88mcg/min
Therefore, for the patient's body weight, the patient's dosage = 99.88mcg/min
Step 3
Available dopamine is 400mg in 250ml
We have to convert this to mcg
Hence,
1 mg = 1000mcg
400mg =
Cross Multiply
= 400mg × 1000mcg
= 400000mcg
Hence, the available dopamine is administer in 250ml/400000mcg
Part 3
Since 60 minutes is 1 hour
The nurse should set the IV pump to deliver how many ml/hr
(99.88mcg/min × 250ml × 60mins)/ 400000mcg
= 3.7455ml/hr
Approximately to the nearest tenth = 3.7ml/hr

-5x² – 2x+10 - x² + 7x +5
Answer:
-6x² + 5x + 15
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of variables.
Reorder based on descending powers:
-5x² - x² + 7x - 2x + 10 + 5
(-5x² - x²) + (7x - 2x) + (10 + 5)
(-6x²) + (5x) + (15)
-6x² + 5x + 15 is your answer.

Percent = 62.5%
f(x) = (2x + 1)(x - 2)(x + 3)
Answer:
f(3) = 42.
Y-intercept is (0, -6).
X-intercepts are (-0.5, 0), ( 2, 0) and (-3, 0).
Step-by-step explanation:
f(3) = (2(3) + 1)(3 - 2)(3 + 3)
= 7 * 1 * 6
= 42.
The y intercept occurs when x = 0:
y-intercept = (2(0) + 1)(0 - 2)(0 + 3)
= 1 *-2*3
= -6.
Calculate the x-intercepts:
(2x + 1)(x - 2)(x + 3) = 0 so
(2x + 1) = 0 or (x - 2) = 0 or (x + 3) = 0
So x = -0.5, 2 or -3.

Jade receives total employment benefits that are 17.5% of her gross annual pay. If Mary has a gross annual pay of $60,500, how much in total job benefits does she receive?
A. $71,087
B. $81,087
C. $61,087
D. $51,087
Answer:
A. $71,087
Step-by-step explanation:
The name jade and Mary contradict each other, let's assume both jade and Mary refers to the same person
Jade receives job benefits of 17.5% of her annual gross pay
Jade has an annual gross pay of $60,500
how much in total job benefits does she receive?
Total job benefits received = 17.5% of $60,500 + $60,500
= (17.5 / 100 * 60,500) + 60,500
= (0.175 * 60,500) + 60,500
= 10,587.5 + 60,500
= $71,087.5
The rounded value closest to the answer in the option is $71,087

I don’t know how to do these problems
Answer: 3/10
Step-by-step explanation: Since our denominators of 2 and 5have no
factors in common, our least common denominator is 2 · 5 or 10.
In order to get a denominator of 10 in each fraction,
we multiply top and bottom of the first fraction by 5
and top and bottom of the second fraction by 2.
That gives us 5/10 - 2/10 which is 3/10.
If 50 percent of the families in a certain city subscribe to the morning newspaper, 65 percent of the families subscribe to the afternoon newspaper, and 85 percent of the families subscribe to at least one of the two newspapers. What percentage of the families subscribe to both newspapers?
Answer: 30%
Step-by-step explanation:
Given, Percent of families subscribe to the morning newspaper = 50%
Percent of families subscribe to the afternoon newspaper = 65%
Percent of families subscribe to at least one of the two newspapers. = 85%
Now, percentage of the families subscribe to both newspapers = % for morning newspaper + % for afternoon newspaper - % for at least one of the two newspapers
= (50+65 - 85) %
= 30 %
Hence, the percentage of the families subscribe to both newspapers = 30%
