Answer:

Using triangle similarity theorems, GF is 16 cm (fourth option)

Step-by-step explanation:

If points S and T are midpoints of the sides of triangle FGH, the segment ST is parallel to the side GF and the triangles FGH and TSH are similars, and their corresponding sides must be proportionals, then:

GF/ST=FH/TH=GH/SH

TH=6 cm→FT=6 cm, because T is the midpoint of side FH, and:

FH=2 TH = 2 FT =2 (6 cm)→FH=12 cm

GS=4 cm→SH=4 cm, because S is the midpoint of side GH, and:

GH=2 GS = 2 SH =2 (4 cm)→GH=8 cm

ST= 8 cm

Replacing the known values in the proportion:

GF/ST=FH/TH=GH/SH

GF/(8 cm)=(12 cm)/(6 cm)=(8 cm)/(4 cm)

GF/(8 cm)=2=2

GF/(8 cm)=2

Solving for GF: Multiplying both sides of the equation by 8 cm:

(8 cm) [GF/(8 cm)]=(8 cm)(2)

GF=16 cm

If Points S and T are midpoints of the sides of triangle FGH, the measure of the length GF is 16cm. Option D is correct

To get the length of Gf, we will need to use the similarity theorem of a triangle as shown:

HT/TS = HF/Gf

From the diagram, we have the following:

HT = FT = 6cm

ST = 8cm

Substitute the given parameters into the formula to have:

6/8 = 6+6/GF

6/8 = 12/GF

6FG = 96

FG = 96/6

FG = 16cm

Hence the measure of the length GF is 16cm

the ratio 6/5 means for every 6 boys there are 5 girls.

Add the ratio: 6+5 = 11

Divide class total by 11: 22/11 = 2

Multiply each ratio number by 2 to find the number of boys and the number of girls:

6 x 2 = 12 boys

5 x 2 = 10 girls.

10 out of the 22 kids are girls.

The probability of picking a girl would be 10/22, which reduces to 5/11

Answer:

Step-by-step explanation:

The aerobics class lasted 20 minutes and the yoga class lasted 50 minutes. This was determined by setting up an equation and solving for the duration of each class, given the total time and the information that the yoga class was 30 minutes longer.

The student is trying to find out how long each class was—Nicole attended an aerobics class and a yoga class for a total of 1 hour and 10 minutes, with the yoga class lasting 30 minutes longer than the aerobics class. To find the answer, we can set up an equation. Let the duration of the aerobics class be x minutes. Therefore, the duration of the yoga class would be x + 30 minutes. According to the question, the total time spent in both classes is 70 minutes (1 hour and 10 minutes).

Now, we can write an equation that represents the total time:

x (aerobics class) + x + 30 (yoga class) = 70 minutes

Combining the x terms we get:

2x + 30 = 70

To find x, we subtract 30 from both sides of the equation:

2x = 40

Dividing both sides by 2 gives us:

x = 20

So the aerobics class lasted 20 minutes, and since the yoga class was 30 minutes longer, it lasted 50 minutes.

For the first question, divide 200 by the seconds. You would get the answer 9.07. This answer is rounded to the nearest hundredth.

The second question, you would convert that to feet by using the units 1 meter = 3.28084.

If you converted it, the answer woudl be 29.75722 ft/second

Final answer:

To find the total number of burgers sold by the fast food restaurant, calculate the burgers sold without cheese using the ratio provided and then find the total by adding burgers with cheese and without cheese.

Explanation:

To find out how many burgers the fast food restaurant sold in total, we first need to determine the number of burgers sold without cheese. Since the ratio of burgers sold with cheese to without cheese is 7:3, we can calculate that for every 7 burgers sold with cheese, 3 were sold without cheese. Therefore, 35 burgers with cheese corresponds to 35 / 7 * 3 = 15 burgers without cheese. Hence, the total number of burgers sold is 35 (with cheese) + 15 (without cheese) = 50 burgers.

B Should be your answer!

Answer:

B. [tex]350x+625[/tex].

Step-by-step explanation:

Let x represent number of weeks.

We have been given that Patricia is starting a part-time job that pays her $350 a week. So the amount saved after x weeks would be [tex]350x[/tex].

We are also told that Patricia has saved $625. So total amount saved by Patricia after x weeks would be [tex]350x+625[/tex].

Therefore, the expression [tex]350x+625[/tex] represent Patricia's total savings after x weeks and option B is the correct choice.

We can write this in expression form as follows:

[tex]\frac{3}{\frac{4}{4} }[/tex]

Notice that we get a 4/4 in the denominator in which case we multiply the two (because they are both denominators:

[tex]\frac{3}{\frac{4}4} } = \frac{3}{16}[/tex]

So, the unit rate is 3/16 lbs/person.

To find the unit rate in pounds per person, divide the total weight of the candy by the number of people. In this case, the unit rate is 3/16 lb per person.

To find the unit rate in pounds per person, we divide the total weight of the candy (3/4 lb) by the number of people (4). This can be represented as 3/4 ÷ 4. To simplify the division, we can multiply the numerator and denominator by 4 to get rid of the fraction. This gives us 3/16 lb per person as the unit rate in pounds per person.

if the terms of a geometric sequence are

[tex]a_{1}[/tex], [tex]a_{2}[/tex], [tex]a_{3}[/tex], [tex]a_{4}[/tex], .....

then the common ratio r = [tex]\frac{a_{4} }{a_{3} }[/tex] = [tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{a_{2} }{a_{1} }[/tex]

Answer:

In a geometric sequence the ratio between consecutive terms is constant.

Step-by-step explanation:

A geometric sequence is that sequence where the ratio between two consecutive terms is constant.

This ratio is called the common ratio.

For example:

Lets take an example :

1,6,36,216,1296,.....

To find the common ration we divide the second term by first term.

[tex]\frac{6}{1} =\frac{216}{36} =6[/tex]

Here, the common ratio is 6.

We find he bikes 17 miles in a full hour.

Brandon bikes 8 and 1/2 miles in 1/2 hour. To find out how far he bikes in 1 hour, we need to double the distance, because one hour is twice as long as half an hour.

Miles per hour = Miles in half an hour * 2 = (8 +  1/2) miles * 2

Now, let's perform the multiplication:

8 * 2 = 16

1/2 * 2 = 1

Therefore, 16 + 1 = 17 miles per hour.

Brandon bikes 17 miles in 1 hour. This is the distance he would cover if he continues at the same pace for a full hour.

Answer:

Step-by-step explanation:

a = -3

Factor out the common term 3.

Cancel 3.

Subtract a from both sides.

Simplify 1 + 2a - a to 1 + a

Subtract 1 from both sides.

Simplify -2 - 1 to -3

Switch sides.

In the magic penny parable, choosing a penny that doubles in value every day leads to a significant amount of money. After 8 days, you would have 256 pennies.

The magic penny parable is a story that demonstrates the power of compound interest. In the story, a person is given the choice between taking a million dollars or a penny that doubles in value every day for 30 days. By choosing the penny, they end up with over 5 million dollars at the end of 30 days.

To determine how much money you would have after 8 days, we can use the formula for compound interest:

Final amount = Initial amount * (1 + interest rate) ^ number of periods

In this case, the initial amount is 1 penny, the interest rate is 100% (as the penny doubles in value), and the number of periods is 8 days.

Using this formula, the calculation would be:

Final amount = 1 penny * (1 + 1)^8 = 1 penny * 2^8 = 1 penny * 256 = 256 pennies.

Therefore, after 8 days, you would have 256 pennies.

B. The equation has one solution.

Step 1. Subtract 2 from both sides

3 + x - 2 = -3x

Step 2. Simplify 3 + x - 2 to x + 1

x + 1 = -3x

Step 3. Subtract x from both sides

1 = -3x - x

Step 4. Simplify -3x - x to -4x

1 = -4x

Step 5. Divide both sides by -4

-1/4 = x

Step 6. Switch sides

x = -1/4

To find the sale price after both markdowns, first apply a 20% markdown to the selling price and then apply a 30% markdown to the resulting price.

To find the sale price after both markdowns, first apply the first markdown of 20%. To do this, multiply the selling price by 0.80 (1 - 0.20), since a 20% markdown is equivalent to selling at 80% of the original price. So, the price after the first markdown is $520 x 0.80 = $416.

Next, apply the second markdown of 30% to the price after the first markdown. Multiply $416 by 0.70 (1 - 0.30) to find the final sale price. $416 x 0.70 = $291.20.

Therefore, the sale price after both markdowns is $291.20.
