x=√34

Answer:

21

Step-by-step explanation:

Since Lilly has read 7/8 of her book (aka 147 pages), divide 147 by 7 and you get 21.

This means 1/8=21

Since she has read 7/8 of the book, and the full book is 8/8, 8/8-7/8= 1/8

Meaning she has 1/8 of the book left to read.

As said before, 1/8 =21

Thus, she has 21 pages left to read.

Answer:

200 words are peter can be type in 5 minutes.

Step-by-step explanation:

As given

If peter can type 80 words in 2 minutes .

i.e

80 words = 2 minutes

Now words type in 1 minutes.

[tex]1\ minutes = \frac{80}{2}\ words[/tex]

1 minutes = 40 words

Now calculate number of words are type in 5 minutes.

Words are type in 5 minutes = Number of minutes × Number of words are type in 1 minutes.

Number of minutes = 5 minutes

Number of words are type in 1 minutes = 40 words

Words are type in 5 minutes = 5 × 40

                                                = 200 words

Therefore  200 words are peter can be type in 5 minutes.

2 pounds is equal to 908 grams (rounded to the nearest whole gram).

Started by converting 2 pounds to kilograms using the conversion factor 1 pound = 0.454 kilograms.

So, 2 pounds * 0.454 kilograms/pound = 0.908 kilograms.

Then, I converted 0.908 kilograms to grams using the conversion factor 1 kilogram = 1000 grams.

So, 0.908 kilograms * 1000 grams/kilogram = 908 grams.

Finally, I rounded 908 grams to the nearest whole gram, which is 908 grams.

Therefore, 2 pounds is equal to 908 grams (rounded to the nearest whole gram).

Question

1 pound = 0.454 kg 1 kg = 1000 g Using the conversions given, convert 2 pounds to grams (round to the nearest whole gram).

Answer:y =0.07272727273 x + 2.587272727

Step-by-step explanation:

Equation of regression line is: y=ax +b

Where, [tex]b=\frac{\sum y\sum x^2-\sum x\sum xy}{n\sum x^2-(\sum x)^2}[/tex]

[tex]a=\frac{n(\sum xy)-\sum x\sum y}{n(\sum x^2)-(\sumx)^2}[/tex]

Here [tex]n =11,\sum y=32.46,\sum x^2=385,\sum x=55,\sum xy=170.3,(\sum x)^2=3025[/tex]

On substituting the values in the formula above for a and b we get:

[tex]b=\frac{32.46\cdot 385-55\cdot 170.3}{11(385)-3025}[/tex]

On simplification we get: [tex]b=2.587[/tex]

[tex]a=\frac{11(170.3)-55\cdot 32.46}{11(385)-3025}[/tex]

On simplification we get: [tex]a=0.0727[/tex]

Answer:

Quantity of wheat in 2015 is 19.8(1.098)(1.051) tons

Step-by-step explanation:

We are given

A farm grew 19.8 tons of wheat in 2013

In 2013:

quantity of wheat =19.8 tons

In 2014:

The farms's wheat output increased by 9.8% from 2013 to 2014

So, quantity of wheat becomes

[tex]=19.8(1+0.098)[/tex]

[tex]=19.8(1.098)[/tex]

In 2015:

The farms's wheat output increased  by 5.1 from 2014 to 2015

so, it is increased by 5.1 % of 2014 quantity

so, we get

quantity of wheat in 2015 is

[tex]=19.8(1.098)(1+0.051)[/tex]

[tex]=19.8(1.098)(1.051)[/tex]

You can calculate how much 9.8% of 19.8 ton is and then add that to 19.8 and add 5.1 more to know the weight of wheat in tons produced in 2015.

The total output of wheat in tons, in 2015 is 26.84 tons.

In 2014, there was increase of 9.8% wheat production than last year(2013).

Thus,

Production in 2014 = Production in 2013 + 9.8% of production in 2013

9.8% of production in 2013 = [tex]19.8 \times \dfrac{9.8}{100} = 1.9404[/tex]

Production in 2014 = 19.8 + 1.94 = 21.74

Production in 2015 = Production in 2014  + 5.1 tons= 21.74 + 5.1 = 26.84 tons

Thus, the total output of wheat in tons, in 2015 is 26.84 tons.

Answer:

The equation of this line is y - 7 = 4(x + 3)

Step-by-step explanation:

To find this, start with the base form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the two coordinates in for (x1, y1).

y - 7 = 4(x + 3)

Final answer:

The equation in Point-Slope form for the given point ( -3,7) and slope 4 is B. y - 7 = 4 ( x + 3 ). (Option B)

Explanation:

The correct equation in Point-Slope form for the given point and slope, where the point is ( -3,7) and the slope is 4, can be written as y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point through which the line passes. Substituting the given values, we obtain y - 7 = 4(x + 3).

Therefore, the correct equation in Point-Slope form is:

288 degree measure could he have rotated the pentagon so that is mapped onto itself

Step-by-step explanation:

Given:  Patrik rotated the pentagon about its center.

A Rotational symmetry of a regular polygon is based on the number of vertices it has.

If the Pentagon figure is rotated [tex]360^{\circ}[/tex] about its center, each vertex lands exactly on the top of where it started.

Since you have 5 vertices, so your starting vertex can land in 5 different starting places and still come up with the same figure.

So if you take [tex]\frac{360}{5} = 72^{\circ}[/tex] rotations to each consecutive vertex.

⇒a rotation of 72 degree, 144 degree, 216 degree, 288 degree and 360 degree will result in the same figure.

Therefore, 288 degree measure could he have rotated the pentagon so that is mapped onto itself.

Answer: Yes option C

Answer: 3 1/4 tons = 6500 tons

Step-by-step explanation:

3 tons is 6000 since 3 * 2000 = 6000

1/4 would be 25% of 2000 which would be 500

because if you take 500 four times it will be 2000

So here you go bud.

3 1/4 tons in pounds.

if 2000 pounds are 1 ton multiply 2000 to 3 tons.

You get 6000.

Then you move on to 1/4.

2000 divided by 4 is 500.

500 is your 1/4.

So 6500 is your answer.

Answer:

Angle 3 is 49 degrees

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

Explanation:

Angle 1 is 50 degrees and angle 2 is 48 degrees. Added up, they total to 98 degrees. This is angle DEF.

Angle DEF is congruent to angle ABC because they are alternate exterior angles and because lines m and n are parallel

We are told that angle ABC is bisected (aka cut in half) because of line s; which means that the angles labeled "4" and "5" are exactly half that of angle ABC = 98 degrees

Therefore, angle 4 is 98/2 = 49 degrees and so is angle 3 (due to angles 3 and 4 being vertical angles; angle 3 = angle 4)

Step-by-step explanation:

Because a triangle must have two equal sides

Final answer:

The sets of measurements that could be the side lengths of a triangle are c (9 cm, 4 cm, 4 cm) and d (7 cm, 10 cm, 8 cm), as they both satisfy the Triangle Inequality Theorem.

Explanation:

The question asks which set of measurements could be the side lengths of a triangle. To determine if three lengths can form a triangle, we can use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. Let's analyze each option:

Therefore, options c (9 cm, 4 cm, 4 cm) and d (7 cm, 10 cm, 8 cm) could be the side lengths of a triangle.

Anya rode at 8.5 miles per hour.

Step-by-step explanation:

We have been given that Taylor and Anya live 63 miles apart. One day they left their houses at 8 am and met at 11 am riding toward each other. Taylor rode at 12.5 miles per hour.

We can see that Taylor and Anya met after 3 hours as 11-8=3. This means that both rode their cycles for 3 hours.

Let us find distance covered by Taylor.

[tex]\text{Distance}=\text{Speed*Time}[/tex]

[tex]\text{Distance covered by Taylor}=12.5\frac{\text{Miles}}{\text{hour}}*3\text{ hours}}[/tex]

[tex]\text{Distance covered by Taylor}=12.5*3\text{ Miles}[/tex]

[tex]\text{Distance covered by Taylor}=37.5\text{ Miles}[/tex]

Therefore, Taylor covered 37.5 miles in 3 hours.

Let us find distance covered by Anya in 3 hours by subtracting distance covered by Taylor from total distance of 63 miles.

[tex]\text{Distance covered by Anya in 3 hours}=(63-37.5)\text{ Miles}[/tex]

[tex]\text{Distance covered by Anya in 3 hours}=25.5\text{ Miles}[/tex]

Now let us find speed at which Anya rode bike.

[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]

[tex]\text{Speed at which Anya rode the bike}=\frac{25.5\text{ Miles}}{3\text{ Hour}}[/tex]

[tex]\text{Speed at which Anya rode the bike}=8.5\frac{\text{ Miles}}{\text{ Hour}}[/tex]

Therefore, Anya rode the bike at the speed of 8.5 miles per hour.

The compound interest for 5 year is $3868.7.

Interest accrued on both the principal sum of money and the interest already earned.

The formula for compound interest is p(1+r/100)ⁿ - p

Where p is principal amount, r is rate and n is time.

Given that,

Principal = $20000,

Time = 5 years,

And rate of interest = 18/5 %

To find compound interest, use formula,

Compound interest =  p(1+r/100)ⁿ - p

Compound interest = 20000(1+18/(5×100))⁵-20000

Compound interest = 23868.7 - 20000

                                 = 3868.7

The compound interest for 5 years is $3868.7.
