Answer:

1.5 hours

Step-by-step explanation:

80 /120= 100/x

80x=12000

12000/80=150

150 minutes- 1.5 hours

Answer:

Around 2 hours and 50 minutes.

Solve

If Jamie can read an 80 page book in 2 hours, divide 100 by the time, 2 hours.

[tex]100 / 2 = 50[/tex]

Add that to the time, 2 hours.

[tex]= 2~hrs.~50~mins.[/tex]

the answer is a for approval

Answer:

[tex]\frac{52}{7}[/tex] [tex]units[/tex]

Step-by-step explanation:

Add up all the sides.

(2a - 3) + (3a + 1) + 2a = 7a - 2

Lets set it equal to 22 since it is the perimeter

7a - 2 = 22

add 2 both sides

7a = 24

a = [tex]\frac{24}{7}[/tex]

From the image, you can tell that 2a -  3 is the shortest side and 3a + 1 is the longest side.

(3a + 1) - (2a - 3)

Substitute [tex]\frac{24}{7}[/tex] in for a.

You should be able to get [tex]\frac{52}{7}[/tex]  units.

Answer:

It will experience a low tide because water is drawn away from the area between the high tides.

Explanation:

The oceans on earth bulge outwards towards the sun and moon due to gravitational pull. This building is highest when the moon and sun are in line (same plane). The coastline within this plane will experience high tides while those at the right angle will have the lowest tides.  

Answer:

Step-by-step explanation:

To find how many it is greater, divide the size of the largest email by the smallest email and both should in bytes. So, convert megabytes and kilo bytes to bytes.

4 kilo bytes = 4* 10³ bytes

8 megabytes = 8 * 10⁶ bytes

[tex]\sf \dfrac{8*10^6}{4*10^3}= 2 *10^{(6-3)}[/tex]

           [tex]= 2*10^{3}\\\\= 2*1000\\\\= 2000[/tex]

Hint:

[tex]\boxed{\dfrac{a^{m}}{a^n}=a^{m-n}}[/tex]

Chord of Contact:-

Equation of the normal chord at any point (at², 2at) of the parabola y² = 4ax is

y + tx = 2at + at³ ....(i)

Look at the attached figure

But if M (x₁, y₁) be it's middle point its equation must be also,

T = S₁

:⟹ yy₁ - 2a (x + x₁) = y₁² - 4ax₁

:⟹ yy₁ - 2ax = y₁² - 2ax₁ .....(ii)

Therefore, from eqs. (i) and (ii) are identical, comparing, them

[tex] \sf \frac{1}{y_1} = \frac{t}{ - 2a} = \frac{2at + {at}^{3} }{ {y_1}^{2} - 2ax} \\ \\ \sf \: from \: first \: two \: relations \: ,t = - \frac{2a}{y_1} ....(iii)\\ \\ \sf \: from \: first \: two \: relations \: , \: \frac{t}{ - 2a} = \frac{2at + {at}^{3} }{{y_1}^{2} - 2ax_1} [/tex]

[tex] \implies \sf \: \frac{{y_1}^{2} - 2ax_1}{ - 2a} = 2a + {at}^{2} \: \\ \\ \implies \sf \: \frac{{y_1}^{2} - 2ax_1}{ - 2a} = 2a + a \bigg \lgroup \frac{ - 2a}{y_1} { \bigg \rgroup}^{2} \qquad\{ \: from \: eqs. \: (iii) \} \\ \\ \implies \sf \:\frac{{y_1}^{2} - 2ax_1}{ - 2a} = \frac{2a{y_1}^{2} + 4 {a}^{3} }{{y_1}^{2}} \\ \\ \implies \sf \: {y_1}^{4} - 2ax_1 {y_1}^{2} = - 4 {a}^{2} {y_1}^{2} - 8 {a}^{4} \\ \\ \implies \sf \: {y_1}^{4} - 2a(x_1 - 2a){y_1}^{2} + 8 {a}^{4} = 0[/tex]

[tex] \sf hence, \: the \: locus \: of \: middle \: point \: (x_1,y_1) \: is \: \\ \\ \qquad \qquad \: \sf \: {y_1}^{4} - 2a(x_1 - 2a){y_1}^{2} + 8 {a}^{4} = 0[/tex]

Answer: x=3

Step-by-step explanation: This is a porportion, meaning that the numbers are set equal to each other. Look at your denominators, 4 and 8? What do they have in common? In this case, they have a factor of 2 in common, and 8 is 4x2. So then we look at the numerators now. What times 2 equals to 6? Your answer then becomes 3.

Answer:

4x³ + 8x² - 7x + 6

Step-by-step explanation:

remove the brackets by distributing the sign.

4x³ + 5x² + 2 + 3x² - 7x + 4

4x³ + 8x² - 7x + 6

Gather like terms.

If you want to factorise (optional)

4x³ + 8x² - 7x + 6 =

4x²(1 + 2x) - 6x + 3 + 3 - x

4x²(1 + 2x) - 3(1 + 2x) + 9 - x

(4x² - 3) (1 + 2x) + 9 - x

Answer:

69p each

Step-by-step explanation:

well if each daisy is 61p you want to multiply that price by 6 to get total daisy price, which is £3.66 Then you take £8.49 from £3.66 to get the total price of the daffodils, which is £4.83. Then you divide the the price by the number of daffodils which is 69p. :))(

Answer:

5^-2 or 1/25

Step-by-step explanation:

use index laws.

1. (A^m)^n = a^mn

5^4 x (5^-3)^2=
5^4 x 5^-6

2. A^m x A^n = A^m+n

5^4 x 5^-6

5^-2=
1/5²=
1/25

Answer:

[tex]5^{4}\times \left( 5^{-3}\right)^{2} =5^{-2}[/tex]

Step-by-step explanation:

[tex]5^{4}\times \left( 5^{-3}\right)^{2} =5^{4}\times 5^{-6}=5^{4-6}=5^{-2}[/tex]

We can write:

[tex]5^{-2}=\frac{1}{5^{2}} =\frac{1}{25}[/tex]

Answer:
Don spent 30 more minutes on his math homework than reading homework.

Step-by-step explanation:

55 - 25 = 30

Answer:

If he mows 3/20 in 1/6 of an hour he'll mow 18/20 or 9/10 in one hour

which means the ratios are equal

1/6:3/20 = 1:18/20 = 1:9/10

Therefore, Jerry will mow 90% of the lawn in one hour

This is a lengthy question ill go through all the formulas

This is a right triangle which means u can use pythagorean theorem to find QP

formula :

[tex]a^{2} +b^{2} =c^{2}[/tex]

Note that [tex]c^{2}[/tex] is always the hypotenuse(the hyp is always opposite to ninety degrees)

so lets substitute

=> [tex]a^{2} +17^{2} =28^{2}[/tex]

=> [tex]a^{2} +289 =784[/tex]

subtract 289 both sides

[tex]= > a^{2}=495[/tex]

Now square root both

[tex]\sqrt{ a}^{2}=\sqrt{495}[/tex]

==> [tex]3\sqrt{55}[/tex] or 22.2 (answer)

But for the other three u have to use another formula any of sin, tan,cos while using For example angle Q and then use any and do inverse it will be very easy after u know all the formulas of Sin,cos, tan

Thats an acronym   for the formula

Sin= Opposite/ hyp

Cos= Adjustent/Hyp

Tan= Opposite/Adjustent
