Answer:  1.4 f or [tex]1f +\frac{4f}{10}[/tex]

Step-by-step explanation:

Since, According to the question,

The snowfall in February in Delphine's house had = f cm

Again according to the question,

In March, Delphine's house had 40% more snowfall than in February.

Therefore, The snowfall in March in Delphine's house had = 140% of The snowfall in February in Delphine's house had

= 140 % of f

= [tex]\frac{f\times 140}{100}[/tex]

= 1.4 f cm

Answer:

the golf ball travels 4,295.52 inches in 20 seconds

Step-by-step explanation:

the ball spins around 340 revolutions per minute

340 revolutions per 60 seconds

60 seconds = 340 revolutions

1 seconds = [tex]\frac{340}{60} = 5.667[/tex]

so its around 5.7 revolutions in 1 second

1 second = 5.7 revolutions

 20 seconds = 5.7 * 20 = 114 revolutions

In 20 second ball spins 114 revolutions

To find distance traveled in 1 revolution we find the circumference of circle

circumference of circle = 2* 3.14 * r

r is the radius = 6 in

circumference of circle = 2* 3.14 * 6= 37.68 inches

In 1 revolution ball travels 37.68 inches

In 114 revolution ball travels 37.68 * 114 = 4295.52 inches

the golf ball travels 4,295.52 inches in 20 seconds

Answer:

L = V / WH

Step-by-step explanation:

Solve for L: V = LWH

To solve, all you have to do is get L on its own on one side.

Because the only operation used in this equation is multiplication, only one operation is needed to solve it: division. Just divide both sides by WH to isolate L.

V / WH = LWH / WH

V / WH = L

[tex]LWH=V\qquad\text{divide both sides by}\ WH\neq0\\\\\boxed{L=\dfrac{V}{WH}}[/tex]

Answer:

£120

Step-by-step explanation:

First calculate 25% of £160 then subtract this from the £160.

25% of 160 = 25/100  * 160

= 1/4 * 160 = £40.

£160 - £40  = £120  (answer).

Answer:

The answer is $120

Step-by-step explanation:

First you must find 25% of $160

First, I found out what is 25% of 16

Next, made 25% = 1/4

Then, 1/4 of 16 is also 16 divided 4 and you will get 4

Then, you add the zero on the back and make it $40

Finally, subtract 40 from 160 and that will be your answer

160 - 40 = $120

Answer:

The equation of the line would be y = -15/24x + 6

Step-by-step explanation:

In order to find the equation of the line, you need to start by using the slope formula with the points given. This will give you the slope.

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

m = (11 - 7/2)/(-8 - 4)

m = (15/2)/-12

m = 15/-24

m = -15/24

Now that we have the slope, we can use that and either point to find the equation in point-slope form.

y - y1 = m(x - x1)

y - 11 = -15/24(x + 8)

y - 11 = -15/24x - 5

y = -15/24x + 6

Answer:The answer on ed is y= -5/8x + 6

Step-by-step explanation:

Answer: choice A. 40 liters

====================================

Explanation:

x = number of liters of the 50% alcohol solution

If we have x liters of 50% alcohol, then we have 0.50*x liters of pure alcohol. This is added to 0.90*40 = 36 liters of pure alcohol (from the 90% solution).

So far we have 0.50*x + 36. This expression represents the total amount of pure alcohol. We want a 70% solution, so we want 70% of the total 40+x meaning 0.50*x + 36 is to be set equal to 0.70*(40+x) and we solve for x as shown below

0.50*x + 36 = 0.70*(40+x)

0.50*x + 36 = 0.70*(40)+0.70*(x)

0.50*x + 36 = 28+0.70*x

36 - 28 = 0.70*x - 0.50x

8 = 0.20x

0.20x = 8

x = 8/0.20

x = 40

So that is why the answer is choice A. 40 liters

the answer is 9x(to the power of 2)−42x+49

Answer:

1) 7/6 or 1 1/6     2)7/55 of a foot longer      3) 13/4 or 3 1/4 cups of milk

4) 56/5 or 11 1/5 feet

Step-by-step explanation:

Let's go over this.

1) If the question asks how much cereal George eats in all, then you must add.

To do this, we must find 2/3 + 1/2. Also, we need to find the common denominator, so that is 6. 2/3 x 2= 4/6. 1/2 x 3= 3/6. Now, it is easier to add. 4/6 + 3/6= 7/6, or 1 1/6.

2) We must find the common denominator again. This is 55, since this is the LCM of 11 and 5. 3/11 x 5= 15/55. 2/5 x 11= 22/55. Now, since the orange fish is longer, 22/55 - 15/55 = 7/55 of a foot longer.

3) This is simple. 13/8 "doubled" is the same as 13/8 x 2, or 13/8 x 2/1. 13 x 2 = 26, and 8 x 1 =8. Our fraction will be 26/8, and we can simplify this to 13/4, or 3 1/4 cups of milk.

4) We can convert these two fractions to improper fractions. 2 1/3 = 7/3, and 4 4/5= 24/5. 7/3 x 24/5= 7 x 24/3 x 5 which is 168/15. The fully simplified fraction is 56/5, or 11 1/5 feet.

5) We must divide 2 1/2 and 4. 2 1/2 = 5/2, and 5/2 divided by 4 is the same thing as 5/2 x 1/4, which is 5/8 of a candy bar.

6) For this problem, we need to find the number of friends. We are supposed to divide 4 and 1/2. 4 divided by 1/2 is equal to 4/1 x 2/1, which is 8. Jack can split his candy bar pieces to 8 friends.

I hope this helped!

Answer:

Relative Size, S, is 1584.89

Step-by-step explanation:

The equation is [tex]R=log_{10}(S)[/tex]

Where,

It is given that in Richter Scale, an earthquake measured 3.2, so [tex]R=3.2[/tex].

They want to know relative size, S, so we put given information in equation and solve for S:

[tex]R=log_{10}(S)\\3.2=log_{10}(S)[/tex]

Converting to exponential form, we have:

[tex]3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932[/tex]

Rounding to nearest hundredth, we have:

[tex]S=1584.89[/tex]

Final answer:

To find the relative size of an earthquake measured at 3.2 on the Richter scale, calculate 10 to the power of 3.2. This results in a relative size of approximately 1584.89 when expressed to the nearest hundredth.

Explanation:

The relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is given by the equation log S = R. If an earthquake measured 3.2 on the Richter scale, we can calculate its relative size by finding the antilogarithm (typically the base 10) of the Richter scale magnitude. This means finding 10 to the power of the magnitude.

To find the relative size for an earthquake that measured 3.2 on the Richter scale:

The relative size or seismic-wave amplitude of the earthquake is therefore approximately 1584.89 when expressed to the nearest hundredth.

9.915 mi and that's all and that helped friend me please thanks stay pretty

Answer:

9.91 miles

Step-by-step explanation:

Refer the attached figure

Forest Ranger at point A observes the fire at angle of 41° north of east i.e.∠CAB = 41°

The distance between the two rangers is 15 miles i.e. AB = 15 miles

Forest Ranger at point B observes the fire at at 56° north of west. i.e.∠CBA= 56°

Now we are supposed to find who is closest to the fire

So, we are supposed to find the length of AC and BC

So, first calculate ∠ACB

We will use angle sum property of triangle

Angle  sum property of triangle  : Sum of all angles of triangle is 180°

So, ∠CBA+∠ACB+∠CAB =180°

56°+∠ACB+41° =180°

97°+∠ACB =180°

∠ACB =180°-97°

∠ACB =83°

Now to find  AC and BC we will use law of sines

[tex]\frac{a}{sin A}=\frac{b}{Sin B}=\frac{c}{SinC}[/tex]

Refer the attached figure

[tex]\frac{AC}{sin 56}=\frac{BC}{Sin 41}=\frac{15}{Sin83}[/tex]

So, [tex]\frac{BC}{Sin 41}=\frac{15}{Sin83}[/tex]

[tex]BC=\frac{15}{Sin83} \times Sin 41[/tex]

[tex]BC=9.91478[/tex]

[tex]\frac{AC}{sin 56}=\frac{15}{Sin83}[/tex]

[tex]AC=\frac{15}{Sin83} \times sin 56[/tex]

[tex]AC=12.5289[/tex]

So, BC< AC

So, the ranger who is closest to fire is at a distance of 9.91 miles .

So, Option 1 is true

Final answer:

The unit rate of 2134 meters in 212 hours is approximately 10.063 meters per hour. This calculation involves dividing the total distance by the total amount of time.

Explanation:

To find the unit rate of 2134 meters in 212 hours, we need to calculate how many meters are covered in one hour. The unit rate is computed by dividing the total distance by the total time.

The calculation is as follows:

Unit rate = Total distance / Total time

Unit rate = 2134 meters / 212 hours

Calculating this gives us a unit rate of approximately 10.063 meters per hour. It's important to make sure that the result is reasonable. If you travel a certain distance in a given number of hours, dividing the distance by the time should give you how many meters you travel in one hour, which in this case, it does.

3149/999 = 3  152/999

Step-by-step explanation:

I'll assume the bar is over 152 and there is a typo.

Use a step-by-step calculator (I recommend Symbolab) OR:

Let x equal 3.152...

1000x = 3152.152...

1000x-x = 3152.152... - 3.152...

999x =

3152.152...

-     3.152...

3149

Cancel out the .152...

999x = 3149

Divide by 999 on each side

x=3149/999 = 3 152/999

Answer:

The given number is 3.152.

Notice that this is a rational number without a repetition pattern, that means we just need to divide all digist without the decimal point by 1000, because the number of zeros always depends on the number of decimals, which are three in this case.

[tex]\frac{3152}{1000}[/tex]

Then, we simplfy

[tex]\frac{3152}{1000}=\frac{1576}{500}=\frac{788}{250}=\frac{394}{125}[/tex]

So, the improper fraction equal to 3.152 is 394/125.

The mixed number is [tex]\frac{394}{125}=3\frac{19}{125}[/tex]

1. Tessellation is the covering of a surface with pattern(s) of flat shapes so that there are no overlaps or gaps. It is also called Tiling.

2. Triangles, Squares, and Hexagons are regular polygons.

3. Previous three shapes create a regular tessellation pattern because all their sides and all their angles are the same. the intersection point of the interior angles is called "Vertex". For a regular tessellation, the pattern is identical at each Vertex.

Unlike the triangle and quadrilateral case, the Pentagon's angle sum of 540° is not helpful when trying to fit a bunch of Pentagons around a vertex. Therefore, even though the Pentagon is a regular polygon, it cannot tessellate.

To find how many cups of flour are needed for every dozen muffins made, set up a ratio using the given information, and solve for x.

Explanation:

To find how many cups of flour are needed for every dozen muffins made, we can set up a ratio using the information given in the question. We know that to make 1 1/2 dozen muffins, 3 1/2 cups of flour are needed. So we can set up the ratio:

1 1/2 dozen muffins : 3 1/2 cups of flour = 1 dozen muffins : x cups of flour

To solve for x, we can cross multiply, and divide:

(1 1/2) * x = (1) * (3 1/2)

x = (1 * 3 1/2) / (1 1/2) = 7/2 cups of flour

Therefore, for every dozen muffins made, 7/2 cups of flour are needed.

UPC (Universal Product Code) is a numeric symbol used in retail products. UPC has two variants, an 11 digit UPC Type A bar code and and 6 digit UPC Type E bar code.

The given UPC code 78007305233 is an 11 digit UPC Type A bar code.

1) From the right to the left, starting with odd position, we need to assign the odd/even position to each digit.

0 E 0 E 0 E 0 E 0 E 0                [0 stands for Odd, E stands for Even]

7 8 0 0 7 3 0 5 2 3 3

2) Summing up all digits in the odd positions and multiplying the result by 3

(7+0+7+0+2+3)*3 = 19 * 3 = 57

3) Summing up all digits in the even positions

8+0+3+5+3 = 19

4) Summing up the results of step three and four

57 + 19 = 76

5) Now, divide the result of the fourth step by 10. The check digit would be the number which adds the remainder to 10. In our case, upon dividing, 76 by 10 we get the remainder 6. The check digit is the result of 10-6 = 4.

(sin²Ф + cos²Ф - 2sinФcosФ) + (sin²Ф + cos²Ф +2sinФcosФ)

We know that : sin²Ф + cos²Ф = 1

So,

( 1 - 2sinФcosФ) + (1 + 2sinФcosФ)

or 1 + 1 -2sinФcosФ + 2sinФcosФ

or 2

Hence we got  (sinФ - cosФ)² + (sinФ + cosФ)² = 2
