1.8*10^3

Answer:

The correct answer is A) 1.8 * 10^-3

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.

100,000 at round tree, 170,000 at Samson. both would be 270,000

20 divided by 1/3 = 6 2/3, therefore Ms Chavez used 6 and two thirds of eggs.

Final answer:

Ms. Chavez will use 6 eggs to make cookies.

Explanation:

Ms. Chavez bought 20 eggs at the market. She will use 30% of these eggs to make cookies.

To find out how many eggs Ms. Chavez will use to make cookies, we can multiply the total number of eggs by the percentage used:

Number of eggs used = 20 × 0.30

Number of eggs used = 6

Therefore, Ms. Chavez will use 6 eggs to make cookies.

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.

Answer: the x-coordinate if the vertex is -3.

The x-coordinate of the parabola’s vertex is 3

from the question, we have the following parameters that can be used in our computation:

y = (x - 6)(x + 12)

When expanded, we have

y = x² - 6x + 12x - 72

So, we have

y = x² + 6x - 72

the x-coordinate of the parabola’s vertex is calculated as

x = -b/2a

So, we have

x = -6/2* 1

Evaluate

x = -3

Hence, the x-coordinate of the parabola’s vertex is 3

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

I got 28%. I divided 14 by 50 to get 0.28. The problem can then be multiplied by 100 to get 28.

Answer:

$236.38

3.20%

Step-by-step explanation:

Simple interest = PNR/100 where P = Principal = 13132/-

N = 8 months = 8/12 years and r = 2.7%

Hence simple interest = 13132 (8/12)(2.7/100)

= 236.376

= 236.38 dollars

-----------------------------------------------------

2) On the same notation, here PNR/100 = 8546(1)(R)/100=273.47

It is 40 because 24/40= 0.6 and 18/30= 0.6 so yeah its 40

Answer:

40

Step-by-step explanation:

We know that DEFG is similar to WXYZ.  This means we can set up a proportion to find the length of the unknown side (let x be the unknown side):

18/30 = 24/x

Cross multiplying,

18(x) = 30(24)

18x = 720

Divide both sides by 18:

18x/18 = 720/18

x = 40

Answer:

The answer is A

Step-by-step explanation:

The distance of 7,500,000 miles expressed in scientific notation is 7.5 × 10⁶, which corresponds to option A) 7.5 × 10⁶.

The spacecraft travels 7,500,000 miles in one year. To express this distance in scientific notation, we need to convert it into the form of a × 10ⁿ, where a is a number between 1 and 10, and n is an integer.

To find the correct form, we can manipulate the original number. We move the decimal point 6 places to the left (since there are six zeros in the million), which gives us 7.5. Thus we can write 7,500,000 as 7.5 × 10⁶. So, the correct answer is A) 7.5 × 10⁶.

The answer is f(x) ≥ 2x^2 + 4x

Hope this helps!

Answer: a) f(x) ≤ -2x^2 + 4x

Step-by-step explanation:

In the graph you can see that the "hands" of the quadratic function go up, this means that the principal constant (the one that multiplicates the square term) is positive:

this is:

for a function f(x) = a*x^2+ b*x + c

if a is positive, the hands will go upside, if a is negative, the hands will go downside.

we also can see that the shaded area is upside the curve, so we are looking for f(x) > something.

Then we can discard the third option because we have f > -2*x^2..

the remaining options are:

a) f(x) ≤ -2x^2 + 4x or f(x) ≥ 2x^2 - 4x

b) f(x) ≥ 2x^2 + 4x

first, you can see that in the second function both terms have the same sign, so there can be only one x-intercept, but in the graph, we can see two x-intercepts, so we can also discard option b.

The remaining option, and the correct one, is option a.

1) -15

2) 5

3) -13

4) -4

5) 5

6) 14

7) 0

8) -8

9) -8

10) 7

These are very easy, when subtracting a negative from a positive think of it as just plain subtraction. When adding a negative to a positive, again, think of it as subtraction. When subtracting two negatives it's basically addition but you final answer should have a negative sign.

Hope I could help! :)

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.
