i remeber this question lol

Step-by-step explanation:

Answer:

(a) [tex]\dfrac{foot \ print \ length }{dinosaurs \ length }= \dfrac{2}{35}[/tex]

(b)The body length of the dinosaur is 525 cm

Step-by-step explanation:

Question

(a) What is the ratio of the length of the footprints in the dinosaur length?

(b) Iris found a new track she believes was made by the same species of dinosaur. If the footprint was 30 cm long and if the same ratio of foot length to body length holds, how long is the dinosaur?

(a)

Given that:

The length of footprint = 40 cm

the thigh bone = 100 cm

the body length = 700 cm

∴

[tex]\dfrac{foot \ print \ length }{dinosaurs \ length }= \dfrac{40}{700}[/tex]

[tex]\dfrac{foot \ print \ length }{dinosaurs \ length }= \dfrac{4}{70}[/tex]

[tex]\dfrac{foot \ print \ length }{dinosaurs \ length }= \dfrac{2}{35}[/tex]

(b)

suppose p,q,r,s are real numbers, where q ≠ 0 & s ≠ 0.

Then:

[tex]\dfrac{p}{q}=\dfrac{r}{s}[/tex] is a proportion if and only if ps = qr

Given that:

length of footprint = 30 cm

If possible the body length of the dinosaur is q (cm)

The length of how long the dinosaur is can be computed as:

[tex]\dfrac{30}{q}=\dfrac{2}{35}[/tex]

2q = 30 * 35

q = (30 * 35)/2

q = 525 cm

Answer:

The slope is 3/4

Please correct me if I am wrong please and thank you

Step-by-step explanation:

I use the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex]

Plug in (2,1) and (-2,-2)

1-(-2)/2-2

= 3/4

Answer:

3/4

Step-by-step explanation:

The slope of this line is 3/4. Slope is the rise over run or the change in y over the change in x. So one way to find the slope is to count how much y and x changes, in this graph between the 2 points y increases by 3 and x increases by 4. So the final slope is 3/4, (if one value decreases then the slope is negative). One way to visually check the slope is to remember that slopes less than -1 or greater than 1 make the line steeper while fraction slopes make the line flatter. Also, you can use the slope formula, [tex]\frac{y_{2-y_{1} } }{x_{2}-x_{1} }[/tex] just plug in the values.

Given:

The three points are (1,2), (2,3) and (-2,-11).

To find:

Whether the given points are collinear.

Solution:

Let as consider the three points are A(1,2), B(2,3) and C(-2,-11).

If these three points are collinear, then area of [tex]\Delta ABC[/tex] must be 0.

Area of [tex]\Delta ABC[/tex],

[tex]Area=\dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]

[tex]Area=\dfrac{1}{2}|1(3-(-11))+2(-11-2)+(-2)(2-3)|[/tex]

[tex]Area=\dfrac{1}{2}|(3+11)+2(-13)-2(-1)|[/tex]

[tex]Area=\dfrac{1}{2}|14-26+2|[/tex]

[tex]Area=\dfrac{1}{2}|-10|[/tex]

[tex]Area=\dfrac{1}{2}(10)[/tex]

[tex]Area=5\neq 0[/tex]

Therefore, the given points are not collinear.

Step-by-step explanation:

We have to find the sum of 102 + 105 + 108 + ... + 996 + 999.

Notice that 102 = 3 * 34 and 999 = 3 * 333. Hence there are 333 - 34 + 1 = 300 terms.

Hence the sum is 300(102 + 999)/2 = 1101 * 150 = 165,150.

The awnser is 165,150

Answer:

[tex]257.74 in^2[/tex]

Step-by-step explanation:

Step one:

Given data

John's cylinder

radius of 7 inches and

height of 10 inches

Required:

The difference in the total surface areas of the two cylinders

[tex]A=2 \pi rh+2 \pi r^2[/tex]

substitute we have

[tex]A=2 *3.142* 7*10+2 *3.142*7^2\\\\A=477.68+307.916\\\\A=785.596 in^2[/tex]

Jeff's cylinder

radius of 6 inches and

height of 8 inches

[tex]A=2 *3.142* 6*8+2 *3.142*6^2\\\\A=301.632+226.224\\\\A=527.856 in^2[/tex]

The difference in the total surface areas is

=785.596-527.856

=257.74 in^2

Answer:

Step-by-step explanation:

Given 3x + 4y + 2 + 6y + 3

Collecting the like terms

3x + 4y + 2 +6y + 3

Add 4y and ^y

3x+10y+2+3

Add 2 and 3

= 3x+10y+5

The coefficient of y is 10

Answer:

<ACB is supplementary to the < ECD by the definition of supplementary angles. Therefore the first part of your answer is <ACB = <ECD

We know that similar triangles have the same corresponding angle measurements for their angles and therefore one of the triangles is just a scaled up or down version of the original. Triangle EDC is a scaled down version of ABC. Therefore, the corresponding sides of triangle ECD have the same ratio to the corresponding sides of ABC. For example line segment EC and BC are corresponding line segment and lets find the ratio: 14/21 = 2/3

THe ratio of EC to BC is 2/3 and the ratio of CD to AC is also 2/3 (18 / 27=2/3)

Therefore, CE / BC is equal to DC / AC

Your full answer is

<ACB = <ECD, CE / BC = DC / AC

So triangle ABC ~ triangle CDE

Answer:

The time needed for Spongebob to swim that distance = 192.77 seconds

Step-by-step explanation:

From the laws of motion, we have that the time it takes a person (in this case, Spongebob) to move from one location to another, or through a distance, equals the distance covered divided by the speed.

i.e time = distance / speed

Velocity of Spongebob's swim = 8.3 m/s

Distance swam = 1600 metres

Time taken = 1600/8.3 = 192.77 seconds

Answer:

192.7 (192.77 to be exact)

Step-by-step explanation:

1600 divided by 8.3 would equal 192.77 (simplified down to 192.7)

Answer:

250 readers

Step-by-step explanation:

1. 4% = 10

2. 100% = 250

a. 4% x 25 = %100

b. 10 x 25 = 250

I hope this helps!

Answer:

250

Step-by-step explanation:

Given that

Letter to the editor = 10

Also it is given that 10 is the 4% of total readers of the newspaper.

Let x be the number of readers of the newspaper

It can be written as:

10=4% of x

Converting the percentage into decimal

10=0.04x

10. = 0.04x

0.04. 0.04

x=250

The newspaper has 250 readers.

Hence,

The local newspaper has 250 readers in total
