Answer:

58°

Step-by-step explanation:

If m AM=125°, then m∠AOM=125°.

If m∠MAF=75°, then m∠MOF=150° (because central angle MOF subtends on the same arc as inscribed angle MAF).

Thus,

m∠FOA=360°-150°-125°=85°.

If mEF=31°, then m∠EOF=31° (as central angle subtended on the arc EF).

Hence,

m∠EOA=m∠EOF+m∠FOA=31°+85°=116°.

Angle EOA is central angle subtended on arc EA, angle AME is inscribed angle subtended on arc AE, thus

m∠AME=1/2m∠EOA=58°.

Answer:

260%

Step-by-step explanation:

To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.

1st year = £245

2nd year = £883

First off, we need to find the difference of the two.

Increase = £883 - £245

Increase = £638

Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.

Percentage increase = [tex]\dfrac{638}{245}*100[/tex]

Percentage increase = [tex]2.60*100[/tex]

Percentage increase = 260%

So the percentage increase of last years payment to this years payment is 260%.

Final answer:

To find the result of 1/8 - 3/7 - 1/8, we need to find a common denominator for the fractions and then subtract them.

Explanation:

To find the result of 1/8 - 3/7 - 1/8, we need to apply the definition of subtraction and properties of operations. First, let's find a common denominator for the fractions. The common denominator for 8 and 7 is 56. Multiply the numerator and denominator of 1/8 by 7 to get 7/56. Multiply the numerator and denominator of 3/7 by 8 to get 24/56. Now subtract the fractions: (7/56) - (24/56) = -17/56. Finally, subtract 1/8 from -17/56. Multiply the numerator and denominator of 1/8 by 7 to get 7/56. Subtract the fractions: (-17/56) - (7/56) = -24/56.

Answer:

34.66 yr

Step-by-step explanation:

The formula for interest compounded continuously is

[tex]A = Pe^{rt}[/tex]

Data:

P = $1400

r = 2 % = 0.02

Calculations:

(a) Calculate A

A = 2 × 1400 = $2800

(b) Calculate t

 [tex]2800 = 1400e^{0.02t}[/tex]

        [tex]2 = e^{0.02t}[/tex]     Divided each side by 1400

 ln2 =  0.02t               Took the ln of each side

     t = ln2/0.02          Divided each side by 0.02

     t = 34.66 yr

It will take 34.66 yr for the investment to double at 2 % interest compounded continuously.

Check:

2800 = 1400e^{0.02×34.66}

2800 = 1400e^{0.6931}

2800 = 1400 × 2

2800 = 2800

Final simplified form is [tex]5\sqrt{5}i[/tex]

Step-by-step explanation:

We have been given an expression [tex]\sqrt{-125}[/tex]

Now we need to simplify [tex]\sqrt{-125}[/tex] and check which choice matches with simplified form of [tex]\sqrt{-125}[/tex].

You missed to provide the choices but still we simplify that.

[tex]\sqrt{-125}[/tex]

[tex]=\sqrt{-5*5*5}[/tex]

[tex]=5\sqrt{-5}[/tex]

When there is negative sign inside square root then we replace that by "i" iota.

Lisa has a total of 8 dresses in her closet. There are 2 red dresses, 3 green dresses, and the remaining 3 are blue dresses.

The subject of the question is probability in Mathematics. In the problem, Lisa has a total of 2 red dresses and 3 green dresses. The quantity of blue dresses is represented by 'x'. It is stated that the probability of choosing a red dress is 25%. Each dress in her closet is an outcome for this probability calculation.

So, in total, she has 2(red dresses) + 3(green dresses) + x(blue dresses) = 100% of the dresses or total outcomes. Since the probability of picking a red dress is 25%, then 2 (red dresses) are 25% of the total outcomes.

To work out the total number of outcomes (total dresses), we calculate 100% ÷ 25% = 4, and then multiply this by the number of red dresses (which is 2), giving us 4*2 = 8 dresses in total.

As we know there are 2 red dresses and 3 green dresses, that leaves 8 (total dresses) - 2 (red) -3 (green) = 3 blue dresses. Thus, Lisa has three blue dresses in her closet.

Lisa has 6 blue dresses.

To find the number of blue dresses Lisa has, we need to set up an equation using the given information.

Lisa has 2 red dresses, 3 green dresses, and x blue dresses. The total number of dresses is 2 + 3 + x = 5 + x.

The probability of choosing a red dress is 25%, which can be written as 0.25.

This means that the number of red dresses divided by the total number of dresses equals 0.25. So, we have 2 / (5 + x) = 0.25.

Solving this equation for x, we find that Lisa has 6 blue dresses.

Answer:

71°

Step-by-step explanation:

Average = [tex]\frac{sum}{count}[/tex]

let x be the temperature in October, then

[tex]\frac{25+70+65+85+92+82+x}{7}[/tex] = 70, that is

[tex]\frac{419+x}{7}[/tex] = 70 ( cross- multiply )

419 + x = 490 ( subtract 419 from both sides )

x = 71

Average temperature in October was 71°

Answer:Instead of dividing the diameter by two to get the radius, the coworker multiplied the diameter by two, getting a value of 340 feet for the radius. Here’s the incorrect calculation:

volume of a cylinder ≈ 3.14 × (radius)2 × height

saving=150

spending=240

Step-by-step explanation:

390/13=30

savings=30*5

spending=30*8

Answer:

£150 saved; £240 spent.

Step-by-step explanation:

If the ratio of savings to spending is 5:8, we find the fractions representing the amount saved and the amount spent by adding up 5 and 8 and then forming fractions:

savings:  5/13

spending:  8/13

(5/13) of £390 is £150; this is the amount saved.

(8/13) of £390 is £240; this is the amount spent.

Answer:

[tex]y=233\frac{1}{3}[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In this problem we have

For [tex]x=1/4, y=25[/tex]

Find the value of k (constant of proportionality)

[tex]y/x=k[/tex] -----> [tex]k=25/(1/4)=100[/tex]

The linear equation is

[tex]y=100x[/tex]

Find the value of y when the value of [tex]x=2\frac{1}{3}[/tex]

substitute the value of x in the equation but first convert to an improper fraction

[tex]x=2\frac{1}{3}=\frac{2*3+1}{3}=\frac{7}{3}[/tex]

[tex]y=100(\frac{7}{3})=\frac{700}{3}[/tex]

convert the result in mixed number

[tex]\frac{700}{3}=\frac{699}{3}+\frac{1}{3}=233\frac{1}{3}[/tex]

Answer:

One rose bush = $3

One bunch of ornamental grass = $4

Step-by-step explanation:

We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:

[tex]14r+7g=70\\5r+14g=71[/tex]

We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:

[tex](*-2)14r+7g=70\\5r+14g=71\\-------\\-28r-14g=-140\\5r+14g=71\\--------\\-23r=-69\\r=\frac{-69}{-23}=3[/tex]

Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:

[tex]14r+7g=70\\14(3)+7g=70\\42+7g=70\\7g=70-42\\7g=28\\g=\frac{28}{7}=4[/tex]

Thus, 1 bunch of ornamental grass is $4.

The answer is C because the 2x outside of the brackers must be negative to produce the beginning term. The next terms are positive and two negatives make a positive, therefore we can conclude that there must be a negative inside the brackets too.

Answer: C. −2x(x−3)(x+2)

Step-by-step explanation:

1. Find the Greatest Common Factor (GCF).

GCF=2x

2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2x(2x^3/2x+−2x^2/2x+−12x/2x)

3. Simplify each term in parentheses.

−2x(x^2−x−6)

4. Factor x^2−x−6

−2x(x−3)(x+2)

The table that best represents the relationship between the number of gallons purchased, g, and the amount paid for gas, m, will list m as multiples of $2.52 as per the linear relationship g: $2.52 * g.

Jimmy pays $2.52 for each gallon of gas. To find the best table representing the relationship between g, the number of gallons purchased, and m, the amount he pays for gas, we need to create a table where each entry form is the product of g and the price per gallon, which is $2.52.

For each gallon g, the total cost m would be:

For 1 gallon: m = 1 * $2.52 = $2.52

For 2 gallons: m = 2 * $2.52 = $5.04

For 3 gallons: m = 3 * $2.52 = $7.56

...and so on.

This pattern will continue since the relationship is linear, and the table representing it will list the total cost m corresponding to the number of gallons g based on this constant rate of $2.52 per gallon.
