Answer:

He had 11 five dollar bills.

Step-by-step explanation:

Since Jonah realized that he had twice as many one dollar bills as he has five dollars bills, and 6 less ten dollar bills as he has one dollar bills, if we say that the number of one dollar bills he has is "x", then the number of five dollar bills and ten dollars bills will be:

five dollar bills = [tex]\frac{x}{2}[/tex]

ten dollar bills = [tex]x - 6[/tex]

Since the total money he had was [tex]237[/tex], then the sum of all the bills he had multiplied by it's respective values must be equal to that:

[tex]\text{(one dollar bills)} + 5*\text{(five dollar bills)} + 10*\text{(ten dollar bills)} = 237\\x + 5*\frac{x}{2} + 10*(x - 6) = 237\\x +\frac{5*x}{2} + 10*x - 60 = 237\\11*x + \frac{5*x}{2} = 237 + 60\\\frac{22*x + 5*x}{2} = 297\\27*x = 297*2\\x = \frac{594}{27} = 22[/tex]

Therefore he had 11 five dollar bills.

Answer: His score is 7.  

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Correct answer = +5

Incorrect answer =-2

Unattempted =0

Ram gets 3 correct and 4 incorrect out of 7 questions.

He attempted 7 questions (3 correct +4 incorrect) so, there are not unattempted questions.

Next, we have to multiply the number of correct questions by the marks given for each correct question ( some process for the incorrect questions)

3 correct = 3 (5) = +15

4 incorrect = 4 (-2) = -8

Adding both results:

+15-8= 7

His score is 7.

Answer:

1 39/50 hours. This is equivalent to 1.78 hours.

Step-by-step explanation:

The sum of the hours of work and the hours for break gives the work day hour which has been given as 8 hours.

Furthermore, given that the break time is 22 1/4%, the number of hours for break

= 22 1/4% × 8 hours

= 89/400 × 8

= 1 39/50 hours

Answer: 76 ft2

Step-by-step explanation:

Perimeter = 2 side length +base length

40 = 2s +12

Solving for s:

40-12 =2s

28 =2s

28/2=s

14ft =side

Since the line which bisects and isosceles triangles is at a right angle to the base we can use the Pythagorean Theorem to find the height (see attachment)  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case 14) and a and b are the other sides. (Base divided by 2 is one side, the other side is the height)

Replacing with the values given:  

14^2= 6^2 + x^2

196 = 36 + x^2

196-36 = x^2

160 = x^2

√160 = x

x = 12.64 (height)

Area of an isosceles triangle = 1/2 x base x height  

A = 1/2 x 12 x 12.64 = 76 ft2

Answer:

Tenth: 6.2

Hundredth: 6.16

Thousandth: 6.159

Step-by-step explanation:

***In general, round up when the number is greater or equal to 5. If number is less, round down***

Rounding to the tenths place means that there will be a SINGLE digit following the decimal. Therefore, 6.1592 rounded to the tenths place will be 6.2 because '5' is equal to 5.

Rounding to the hundredths place means that there will be TWO digits following the decimal. Therefore, 6.1592 rounded to the hundredths place becomes 6.16 because '9' is greater than 5.

Rounding to the thousandths place means that there will be THREE digits after the decimal. 6.1592 rounded to the thousandths place becomes 6.159 because the digit to the right of the thousanths place is '2', meaning you round down. The digit in the thousandths place will stay the same.

Answer:

Please see attached image for the graph

Step-by-step explanation:

To graph the elevation versus time, we start by plotting the first point at time zero (when the climb begins) when Zane is 20 meters below the edge (-20 meters). This corresponds to the point (0, -20).

One second later (1 in the horizontal axis), Zane has moved up 4 meters, now reaching -16 meters. This is the point (1, -16) on the graph.

One second later at time 2 seconds, he is another 4 meters up which corresponds to the point (2, -12) on the graph.

you can go on like this plotting more points on the graph.

Please see the attached image that illustrates this and shows the appropriate line that represents Zane's position versus time (pictured in red)

Answer:

D. y/-1 = f(x)

Step-by-step explanation:

because if you were to move the -1 to the other side by multiplying both sides by -1, you would get f(x) times -1 which would give you the negative equivalent of the original equation f(x)

Answer:

y=x+1

Step-by-step explanation:

The slope intercept form of a line is y=mx+b, where m is the slope of the line and b is the y intercept. Since the line rises one unit for every one unit it moves to the right, it has a slope of 1. Since it intersects the y axis at the point (0,1), it has a y intercept of 1. Therefore, the equation is y=x+1. Hope this helps!

Answer:

Step-by-step explanation:

Given: bacteria to increase from 2000 to  50,000

To find: Number of days that a culture of bacteria will take to increase from 2000 to  50,000

Solution:

The growth of bacteria is represented by the equation: [tex]P(t)=P_0e^{kt}[/tex]

Here, t denotes time, k denotes growth rate and [tex]P_0[/tex] denotes initial population of bacteria.

Take [tex]P_0=2000[/tex], [tex]P(t)=50000[/tex] and [tex]k=0.657[/tex]

[tex]50000=2000e^{0.657t}\\\frac{50000}{2000}=e^{0.657t}\\25=e^{0.657t}\\0.657t=\ln 25\\t=\frac{\ln 25}{0.657}=4.9\approx 5\,\,days[/tex]

Answer:

[tex]n^2+5n+2[/tex]

Step-by-step explanation:

Given the sequence

8, 16, 26, 38, 52, 68, 86,...

The nth term of a quadratic sequence will take the form:

[tex]an^2+bn+c[/tex]

Step 1: Find the difference between each term

The differences are: 8,10,12,14,...

Step 2: Find the differences between the differences

We notice an addition of 2, so the second difference is 2.

Step 3:

Take the half of the second difference to obtain a.

2/2=1

Therefore: a=1

The sequence for now is: [tex]n^2+bn+c[/tex]

Step 4: Find [tex]T_n-n^2[/tex]

[tex]T_1=8, T_1-1^2=8-1=7\\T_2=16, T_2-2^2=16-4=12\\T_3=26, T_3-3^2=26-9=17[/tex]

We notice that [tex]T_n-n^2[/tex] forms a linear sequence 7,12,17

We can write this as 2+5n

Therefore, Our nth rule for the quadratic sequence is therefore: [tex]n^2+5n+2[/tex]

Answer:

x = ±4

Step-by-step explanation:

3x^2 =48

Divide by 3

3x^2/3 = 48/3

x^2 = 16

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4

Answer:

x = ± 4

Step-by-step explanation:

You need to get [tex]x^2[/tex] by itself, and to do this, you divide both sides by 3, like so:

[tex]3x^2 = 48\\x^2 = 16[/tex]

Now take the square root of both sides:

[tex]\sqrt{x^2} =\sqrt{16} \\[/tex]

x = ± 4

Hai

first i wanna find the full area. so ill multiply

14×10 = 140.

now the things i should do is find patch and bed's area and substrack from the all area to find the lawn!

For flower bed:

3×8= 24, 24÷2 = 12.

for vegetable patch:

5+7= 12×10 = 120÷2 = 60.

60+12=72

140-72= 68

good luck (:

Answer:

One real root (multiplicity 2).

Step-by-step explanation:

-3=x^2+4x+1

x^2 + 4x + 4 = 0

Discriminant = 4^2 - 4*1*4 = 0

There is one real root (multiplicity 2).

The equation has 1 real solution.

The quadratic function is given as:

[tex]-3=x^2+4x+1[/tex]

Add 3 to both sides of the equation

[tex]3-3=x^2+4x+1 + 3[/tex]

This gives

[tex]0=x^2+4x+4[/tex]

Rewrite the equation as:

[tex]x^2+4x+4 = 0[/tex]

A quadratic equation is represented as:

[tex]ax^2+bx+c = 0[/tex]

By comparison, we have:

[tex]a =1[/tex]

[tex]b =4[/tex]

[tex]c = 4[/tex]

The discriminant (d) is calculated as:

[tex]d =b^2 - 4ac[/tex]

So, we have:

[tex]d =4^2 - 4 \times 1 \times 4[/tex]

[tex]d =16 - 16[/tex]

Evaluate like terms

[tex]d = 0[/tex]

Given that the discriminant value is 0, it means that the equation has 1 real solution.

Answer:

Step-by-step explanation

Here, we want to select what is true of the function.

The correct answer is that the variable x represents the independent variable

It represents the independent variable because the values of x does not depend on the values of g(x). In fact, the value of g(x) are dependent on the values gotten through the substitution of the different values of x into the equation.

Thus, we can confidently say that the function g(x) is the dependent variable as its values depend on the value for that x
