Answer:

Lily babysit for less than 4 hours.

Step-by-step explanation:

Given:

Lucy spends in a week babysitting for 4 hours.

Lily spends seven-eighths of 4 hours.

Now, to find whether Lily babysit for more than 4 hours or less than that.

Number of hours Lucy babysit = 4 hours.

So, to get the hours Lily babysit:

[tex]\frac{7}{8}\ of\ 4\ hours.[/tex]

[tex]=\frac{7}{8}\times 4\\\\=\frac{28}{8} \\\\[/tex]

On simplifying we get:

[tex]=\frac{7}{2} \\\\=3\frac{1}{2}\ hours.[/tex]

Thus, Lily spends [tex]3\frac{1}{2}\ hours[/tex]  for babysitting which is less than 4 hours.

Therefore, Lily babysit for less than 4 hours.

Lily babysits for 3.5 hours weekly, which is less than Lucy's 4 hours of babysitting.

Lucy spends 4 hours a week babysitting, and Lily spends seven eighths as much time babysitting. To calculate how much time Lily spends, we multiply Lucy's hours by seven eighths:

4 hours × (7/8) = 28/8 hours = 3.5 hours.

So, Lily babysits for 3.5 hours a week, which is less than 4 hours.

Answer:

8,760

Step-by-step explanation:

If Kaylah is reading 142 words in one minute, there is 60 minutes in an hour.

therefore,

142 x 60 = 8,760

Answer:

8520 minutes

Step-by-step explanation:

To solve, make a proportion

142 words in 1 minute, and x words in 60 minutes (1 hour).

142/1=x/60

Cross multiply

142*60=1*x

8520=x

Another way to solve is to know that each hour has 60 minutes, and she can read 142 words in 1 minute. So, we can just multiply 60 and 142.

60*142=8520

Answer:

The volume of a cone that fits perfectly inside the soda can is 7.

Volume of a can:

21 = r² π h

21 = 3² π h

21 = 9 π h

h = 21/ 9π = 7/ 3π 

Volume of a cone that fits perfectly inside a can:

V = 1/3 r² π h = 1/3 · 9 π · 7 / 3π = 7

Or you can use: V cone = 1/3 V cylinder ( with the same basis )

V cone = 1/3 * 21 = 7

Step-by-step explanation:

Since we have given that

Volume of soda can = 21

Diameter of can = 6

As we know the formula for "Volume of cylinder:"

Now, we have to find the volume of a cone that fits perfectly inside the soda can.

so, its radius will be 3 cm and height will be

As we know the formula for "Volume of cone":

Hence, the volume of a cone that fits perfectly inside the soda can is 7.

Answer:

1/3

Step-by-step explanation:

In order to solve using substitution, we'll need to first isolate one variable in one equation. I will be using 7x - 2y = 3 and solving for y to begin.

7x - 2y = 3

-2y = -7x + 3

2y = 7x - 3

y = 3.5x - 1.5

Next, we'll plug in our value of y (found above) into the equation 3x + 4y = 11 and solve for x.

3x + 4(3.5x - 1.5) = 11

3x + 14x - 6 = 11

17x = 17

x = 1

Finally, we'll plug our value of x in to the first equation (7x - 2y = 3) and solve for y.

7(1) - 2y = 3

7 - 2y = 3

-2y = -4

y = 2

The solution to these equations is (1, 2).

Hope this helps! :)

Answer:

The equation of the line is y = 3 x - 5.

Step-by-step explanation:

The slope intercept form of the equation of a straight line is:

[tex]y=mx + b[/tex]

Here,

m = slope

b = intercept.

The two points are:

A = (2, 1)

B = (3, 4)

Use two-point form method to determine the equation of straight line.

[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\ (x-x_{1})[/tex]

 [tex](y-1)=\frac{4-1}{3-2}\ (x-2)[/tex]

    [tex]y-1=3(x-2)\\y-1=3x-6[/tex]

          [tex]y=3x-5[/tex]

Thus, the equation of the line is y = 3 x - 5.

The equation of the line in slope-intercept form is y = 3x - 5.

To find the equation of the line containing the points (2, 1) and (3, 4) in slope-intercept form (y = mx + b), you first need to determine the slope (m) and then use one of the points to solve for the y-intercept (b).

The slope (m) can be found using the formula:

m = (y2 - y1) / (x2 - x1)

Let's plug in the coordinates of the two points:

Point 1: (x1, y1) = (2, 1)

Point 2: (x2, y2) = (3, 4)

Now, calculate the slope (m):

m = (4 - 1) / (3 - 2)

m = 3 / 1

m = 3

Now that you have the slope (m), you can use one of the points, for example, (2, 1), and the slope to find the y-intercept (b). You can use the point-slope form of the equation:

y - y1 = m(x - x1)

Using the point (2, 1):

y - 1 = 3(x - 2)

Now, distribute the 3 on the right side:

y - 1 = 3x - 6

Next, add 1 to both sides to isolate y:

y = 3x - 6 + 1

Simplify:

y = 3x - 5

Answer:$253

Step-by-step explanation: A=220(1+(0.05*3))=253

Answer:

B) 65°

Step-by-step explanation:

The formula for this would be x = 1/2 (a -b)

X being the angle you're trying to find

a being the larger arc and b being the smaller arc

Since a circle has 360°, and 245 is the larger arc, the smaller arc would be 115°

Now, just plug that into the equation; x = 1/2 (245-115)

This gives you x = 1/2 (130)

x = 65°

Answer: the first number is 11 38/41

The second number is 10 4/41

Step-by-step explanation:

Let x represent the first number.

Let y represent the second number.

4 times one number plus 3 times the other is 78. It means that

4x + 3y = 78- - - - - - - - - -1

3 times the first number minus 8 times the other is -45. It means that

3x - 8y = - 45- - - - - - - - - 2

We would eliminate x by multiplying equation 1 by 3 and equation 2 by 4. It becomes

12x + 9y = 234

12x - 32y = - 180

Subtracting, it becomes

41y = 414

y = 414/41

y = 10 4/41

Substituting y = 414/41 into equation 1, it becomes

4x + 3 × 414/41 = 78

4x + 1242/41 = 78

4x = 78 - 1242/41

4x = 1956/41

x = 1956/41 × 1/4

x = 1956/164

x = 11 38/41

60% of 94 is calculated by multiplying 94 by 0.60, which results in 56.4.

To find 60% of 94, you will multiply 94 by 0.60. Performing this calculation:

60% of 94 = 0.60 * 94

0.60 * 94 = 56.4

So, 60% of 94 equals 56.4.

Explanation:

If the data wasn't sorted, then the first step would be to arrange the elements from smallest to largest. However, that is already done for us.

The middle most value in the set {15, 19, 20, 25, 31, 38, 41} is 25 because there are three values below it {15,19,20} and three values above it {31,38,41}

Focus on the lower half {15,19,20} and note the middle of this subset is element 19. This is the value of Q1 or the first quartile.

The third quartile Q3 is 38 because the middle of the upper half data set {31,38,41} is 38.

We now subtract the values of Q3 = 38 and Q1 = 19 to get the interquartile range (IQR)

IQR = Q3 - Q1 = 38 - 19 = 19

Answer:

FIRST FOUR (4) TERM = 6, 18, 54,162.

COMMON RATIO = 3

Step-by-step explanation:

In geometric expression.

Tn = the nth term

a = first term

r = common ratio.

Let's take the First term of the G.P as 6 and the third term as 54. Let's find the common ratio.

3rd term will be written as:

T3 = ar² = 54

Given the first term as 6.

T3 = 6r² = 54

6r² = 54

r² = 54 / 6

r² = 9

r= √9

r = 3

Therefore common ratio = 3.

Let's use this information to get the fourth term.

T4 = ar³

when a = 6

and r = 3.

T4 = 6 * 3³

T4 = 6 * 27

T4 = 162

The first four terms of the geometric sequence are [tex]\(a_1 = 5\), \(a_2 = 15\), \(a_3 = 45\), and \(a_4 = 135\).[/tex]  The common ratio is r= 3 and the rule for the nth term is [tex]\(a_n = 5 \cdot 3^{(n-1)}\).[/tex]

To find the common ratio r of a geometric sequence, one divides a term in the sequence by the previous term.

Given the first four terms as [tex]\(a_1 = 5\), \(a_2 = 15\), \(a_3 = 45\), and \(a_4 = 135\),[/tex] we can calculate the common ratio using the first two terms:

[tex]\[ r = \frac{a_2}{a_1} = \frac{15}{5} = 3 \][/tex]

We can verify this by calculating the ratio of the third term to the second term:

[tex]\[ r = \frac{a_3}{a_2} = \frac{45}{15} = 3 \][/tex]

And again with the fourth term and the third term:

[tex]\[ r = \frac{a_4}{a_3} = \frac{135}{45} = 3 \][/tex]

Since the ratio is consistent across these terms, we can confirm that the common ratio r is indeed 3.

The rule for the nth term of a geometric sequence is given by:

[tex]\[ a_n = a_1 \cdot r^{(n-1)} \][/tex]

[tex]\[ a_n = 5 \cdot 3^{(n-1)} \][/tex]

This is the rule for the nth term of the given geometric sequence.

Look at the numerator of the fraction. You will see 7^5, or 7 to the 5th power. This means you must multiply 7 by itself 4 times, to get yourself the numerator of 7 x 7 x 7 x 7 x 7. This means your choices are B (or the second option from the top) or D (or the last option from the top).

However, take note that your original equation is a fraction, meaning you would divide, and not multiply. This means B, or the second option, is incorrect, because they are multiplying in that expression, when a fraction means to divide.

Your only other option is D, where they have portrayed both 7 to the fifth correctly in the numerator, and then 7 squared in the denominator.

Answer:

you would multiple length base and height together and since they're all 6 centimeters you would multiply 6 by 6 by 6 and you get216 cubic centimeters

Hope this helps!

Step-by-step explanation:

The volume of a cube with a side length of 6 cm is 216 cm³. Since we know that volume of a cube is obtained by multiplying its side length three times.

The volume of  a cube is given as:

Volume = [tex]s^3[/tex]

Where 's' is the length of its side

Since all the side lengths of a cube are the same, the volume of a cube can be found by multiplying the edge length three times.

Given that the length of the side of a cube is s=6 cm

Then, the volume of the cube is:

Volume = s³

             = 6³

             = 6 × 6 × 6

             = 216 cm³

Therefore, the volume of the cube is 216 cubic centimeters.

Answer:

T is 13.9 years to the nearest 10th of a year

Step-by-step explanation:

In this question, we are to calculate the number of years at which someone who invests a particular amount will have a particular amount based on compound interest.

To calculate the number of years, what we do is to use the compound interest formula.

Mathematically,

A = P(1+ r/n) ^nt

Where A is the final amount after compounding all interests which is $19,200 according to the question

P is the initial amount invested which is $10,000 according to the question

r is the rate which is 4.75% according to the question = 4.75/100 = 0.0475

n is the number of times per year in which interest is compounded. This is 2 as interest is compounded semi-annually

t= ?

we plug these values;

19200 = 10,000(1+0.0475/2)^2t

divide through by 10,000

1.92 = (1+0.02375)^2t

1.92 = (1.02375)^2t

We find the log of both sides

log 1.92 = log [(1.02375)^2t)

log 1.92 = 2tlog 1.02375

2t = log 1.92/log 1.02375

2t = 27.79

t = 27.79/2

t = 13.89 years

The question asks to give answer to the nearest tenth of a year and thus t = 13.9 years
