Answer:
He has to route 23 calls
Step-by-step explanation:
If he spends 2 mins in each phone call, and he'll spend 46 mins routing calls. Your answer is 23 sense 46 divided by 2 is 23
Robert have to route 23 phone calls to spend a total of 46 minutes on the phone.

Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of \$65$65dollar sign, 65 along with an hourly rate of \$28$28dollar sign, 28. The plumber only charges for a whole number of hours. Anand would like to spend no more than \$250$250dollar sign, 250, and he wonders how many hours of work he can afford. Let HHH represent the whole number of hours that the plumber works. 1) Which inequality describes this scenario? Choose 1 answer: Choose 1 answer: (Choice A) A 28+65H \leq 25028+65H≤25028, plus, 65, H, is less than or equal to, 250 (Choice B) B 28+65H \geq 25028+65H≥25028, plus, 65, H, is greater than or equal to, 250 (Choice C) C 65+28H \leq 25065+28H≤25065, plus, 28, H, is less than or equal to, 250 (Choice D, Checked) D 65+28H \geq 25065+28H≥25065, plus, 28, H, is greater than or equal to, 250 2) What is the largest whole number of hours that Anand can afford? hours
Answer: (1) C. 65 + 28H < 250
(2) 6
Step-by-step explanation:
Here is the correct question:
Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of $65 along with an
hourly rate of $28. The plumber only charges for a whole number of hours. Anand would like to spend no more than $250, and he wonders how many hours of work he can afford.
Let H represent the whole number of hours that the plumber works.
1) Which inequality describes this scenario?
Choose 1 answer:
A. 28 + 65H < 250
B. 28 + 65H > 250
C. 65 + 28H < 250
D. 65 +28H > 250
2) What is the largest whole number of hours that Anand can afford?
Since the initial fee charged by the plumber is $65 and an hourly rate of $28, and Anand would like to spend no more than $250. This means that the addition of the initial fee plus the hourly fee based on number of hours worked will have to be less than $250. This can be mathematically expressed as:
= 65 + 28H < 250
That means option C is the correct answer.
Option B and D are incorrect because the greater sign was used but Anand doesn't want to spend more than $250 but the options denoted that he spent more than $250 which isn't correct.
2)'The largest whole number of hours that Anand can afford goes thus:
65 + 28H < 250
28H < 250 - 65
28H < 185
H < 185/28
H < 6.6
Therefore, the largest whole number of hours that Anand can afford is 6.
Answer: The Answer is 65+28H < 250 and the largest amount of hours is 6

Step-by-step explanation:
Let us multiply the two trinomials and simplify the product to find the correct choice.
[tex](2x^{2}+4x-3)(x^{2}-2x+5)[/tex]
To find the product multiply each term in the first bracket by the second bracket, then add the like terms
[tex]2x^{2} (x^{2}-2x+5)=2x^{2}(x^{2})+2x^{2}(-2x)+2x^{2}(5)=2x^{4}-4x^{3}+10x^{2}[/tex]
[tex]4x(x^{2}-2x+5)=4x(x^{2})+4x(-2x)+4x(5)=4x^{3}-8x^{2}+20x[/tex]
[tex](-3)(x^{2}-2x+5)=(-3)(x^{2})+(-3)(-2x)+(-3)(5)=-3x^{2}+6x-15[/tex]
Now let us add the like terms.
[tex]2x^{4}-4x^{3}+10x^{2}+4x^{3}-8x^{2}+20x-3x^{2}+6x-15=[/tex]
[tex]2x^{4}+(-4x^{3}+4x^{3})+(10x^{2}-8x^{2}-3x^{2})+(6x+20x)-15=[/tex]

Suppose Q is the midpoint of PR. PR = 9x - 31 and QR = 43. Find X
Greetings from Brasil...
Since Q is the central point of PR, then PQ = QR and PQ = PR/2 or QR = PR/2
QR = PR/2
PR = 2 · QR
9X - 31 = 2 · 43
X = 13The value of x is 13.
What is a line segment ?A line segment is basically a line which has two end points.
A line has always a linear equation which has highest degree of 1
According the given question
Line segment is PR and midpoint is Q
Given QR = 43 which one end to the midpoint
∴ Total length of the line segment is 2×43
= 86
Given PR = 9x - 31 which is the total length of the line segment.
∴ 9x - 31 = 86
9x = 86 + 31
9x = 117
x = 117/9
x = 13.

Complete question is;
Determine whether the given procedure results in a binomial distribution. If it is not binomial, identify the requirements that are not satisfied.Randomly selecting 50 adults and asking if they like rap music on a scale of 1 - 10.
Choose the correct answer below.
A. No, because the probability of success does not remain the same in all trials.
B. Yes, because all 4 requirements are satisfied.
C. No, because there are more than two possible outcomes and the trials are not independent.
D. No, because there are more than two possible outcomes.
Answer:
Option D: No, because there are more than two possible outcomes.
Step-by-step explanation:
A binomial distribution is simply defined as the probability of having an outcome in an experiment or survey that is either a success or a failure and having it repeated multiple times. Therefore, we can say that binomial distribution is a type of distribution that has only two possible outcomes.
Now in the question, 50 adults are selected randomly and asked if they like rap music on a scale of 1 - 10. It means there is a possibility of having more than two outcomes. Therefore, it means it is not binomial.
Convert 7.2 ⋅ 10^−3 to standard form.
Answer:
0.0072
Step-by-step explanation:
=7.2 × 10^-3
=7.2 × 10/10000
=7.2 ×1/1000
=0.0072
Answer:
0.00072
Step-by-step explanation:
Step 1: We know that we will have 3 zeros because of the exponent, and the exponent happens to be negative, so we will have the 3 zeros in after the decimal point (obviously), but before any numbers.
Step 2: We will then convert the 7.2 into 72, and it will also go after the decimal point. It will also go after the 3 zeros.
Step 3: Put it all together. The 0 (0), the decimal point (0.), the three zeros (0.000), and the 72 (0.00072). 0.00072 is your answer!

What is the angle of C (C)?
С
65°
65°
Answer:
50°
Step-by-step explanation:
The missing angle, <C, is an angle on a straight line with the two other angles who measures are 65% each.
Therefore:
65 + 65 + C = 180° (angles on a straight line)
130 + C = 180
Subtract 130 from both sides
130 + C - 130 = 180 - 130
C = 50°

m=ad-2f^2 (find a) and 1/3HB=T (find B) please help im so lost
Answer:
[tex]a=\frac{m+2f^2}{d}\\\\ B=\frac{3T}{H}[/tex]
Step-by-step explanation:
1.) Find a
Solve the given equation for a (change it to lool like a=...). Isolate the variable a to find its value. Subtract 2f² from both sides:
[tex]m+2f^2=ad-2f^2+2f^2\\\\m+2f^2=ad[/tex]
Divide both sides by d:
[tex]\frac{m+2f^2}{d}=\frac{ad}{d}\\\\ a=\frac{m+2f^2}{d}[/tex]
2.) Find B
Solve the equation for B (change it to look like B=...). Isolate the variable B to find its value. Simplify:
[tex]\frac{1}{3}HB=T\\\\\frac{HB}{3}=T[/tex]
Multiply both sides by 3:
[tex]3(\frac{HB}{3})=3(T)\\\\ HB=3T[/tex]
Divide both sides by H:
[tex]\frac{HB}{H}=\frac{3T}{H}\\\\ B=\frac{3T}{H}[/tex]

The Geology Club of Gilroy Middle School took a field trip to Nisene Marks State Park to visit the epicenter of the 1989 earthquake. There were 3 adults for every 8 students on the field trip. A total of 44 people went on the field trip. How many adults were on the field trip?
Answer:
12 adults
Step-by-step explanation:
We can solve this in a couple of simple steps. First, since there are 3 adults for every 8 students we add these two numbers together
3+8 = 11
Now we simply divide this number by the total amount of people that went to the trip in order to get how many times this set of adults and students repeats itself.
44 / 11 = 4
Finally, we multiply this number by the set of 3 adults in order to find out how many adults went to the trip.
4 * 3 = 12 adults
8 * 3 = 32 Students
