Answer:

17 to 24

25 to 32

Step-by-step explanation:

8-1=7

16-9=7

therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32

Answer: 17 to 24 then 25 and 32

Find the product:-

[tex] \tt \dfrac{18}{30} \times \dfrac{5}{4} [/tex]

[tex] = \tt \dfrac{18 \times 5}{30 \times 4} [/tex]

[tex] = \tt \cancel\dfrac{18 \times 5}{30 \times 4} = \boxed{\tt\dfrac{ \: \: 3 \: \: }{4}} \: \: \: \: \: \: \: \: \: [/tex]

Multiply:-

[tex] \tt4 \: \dfrac{1}{8} \times \dfrac{1}{9} [/tex]

[tex] = \tt \dfrac{25}{8} \times \dfrac{1}{9} [/tex]

[tex] = \tt\dfrac{25}{8} \times \dfrac{1}{9} [/tex]

[tex] = \tt \cancel\dfrac{25 \times 1}{8 \times 9} = \cancel{ \tt\dfrac{ \: \: 25 \: \: }{72}} [/tex]

[tex] = \boxed{\tt\dfrac{ \: \: 1 \: \: }{3 }} [/tex]

Find the product:-

[tex] \tt \dfrac{15}{18} \times \dfrac{6}{9} \times \dfrac{27}{21} [/tex]

[tex] = \tt \cancel\dfrac{15 \times 6 \times 27}{18 \times 9 \times 25} [/tex]

[tex] = \boxed{\tt \dfrac{ \: \: 5 \: \: }{7}} [/tex]

Multiply:-

[tex] \tt \: 3 \: \dfrac{7}{70} [/tex]

[tex] = \tt \cancel\dfrac{3 \times 7}{1 \times 70} = \boxed{ \tt\dfrac{ \: \: 3 \: \: }{10}} [/tex]

Solve:-

[tex] \tt(6 \times \dfrac{1}{4}) \times \dfrac{1}{2} \times \dfrac{1}{2} [/tex]

[tex] = \tt \cancel{( \dfrac{3 \times 1}{1 \times 2} )} \times \dfrac{1}{2} \times \dfrac{1}{2} [/tex]

[tex] = \tt(\dfrac{3}{ \: \: 2 \: \: }) \times \dfrac{1}{2} \times \dfrac{1}{2} [/tex]

[tex] = \tt\dfrac{3}{ 2 } \times \dfrac{1}{2} \times \dfrac{1}{2} \: \: \: \: \: \: \: \: = \boxed{ \tt \dfrac{ \: \: 3 \: \: }{8}} [/tex]

Answer:

One solution, x=-18/11.

Step-by-step explanation:

y=1/2x-7

y=6x+2

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

1/2x-7=6x+2

1/2x-7-6x=2

1/2x-6x=2+7

1/2x-12/2x=9

-11/2x=9

x=9/(-11/2)

x=(9/1)(-2/11)

x=-18/11

[tex]7x + 12 = 9x - 6[/tex]

[tex]7x + 12 - 7x = 9x - 6 - 7x[/tex]

[tex]12 = 2x - 6[/tex]

[tex]12 - 6 = 2x -6 - 6[/tex]

[tex]6 = 2x - 12[/tex]

[tex]6 + 12 = 2x[/tex]

[tex]18 = 2x[/tex]

[tex]18 \div 2 = x[/tex]

[tex]9 = \bold{ x}[/tex]

In pythagoras, c is the hypotenuse. That is AC. Where a is AB and b is BC.

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

[tex] {(6 x + 5)}^{2} = {(7x + 12)}^{2} + {BC}^{2} [/tex]

[tex] {((6 \times 9) + 5)}^{2} = {((7 \times 9)}^{2} + 12)^{2} +{BC}^{2} [/tex]

[tex] {(54 + 5)}^{2} = {(63 + 12)}^{2} + {BC}^{2} [/tex]

[tex] {59}^{2} = {75}^{2} + {BC}^{2} [/tex]

[tex]3481 = 5625 + {BC}^{2} [/tex]

[tex]3481 - 5625 = {BC}^{2} [/tex]

[tex] - 2144 = {BC}^{2} [/tex]

[tex] \sqrt{ - 2144} = BC[/tex]

Answer:

Interest wil be 10% of 100  which is 10

So,  interest will be Rs.10

And total amount to be payed will be 100+10 which is Rs.110

Answer:

Interest= Rs. 10

Step-by-step explanation:

Interest of Rs.100 on 10 p.c.p.a is 10% of 100

i.e., 100*10/100 = 10

Thus we have 10 as the interest

If the shipping is for all books then the total cost is 164.95

Answer:

Your answer is.......

x^3 + 2x^2 + 4x + 8=0 Note.. if x=-2 then whole equation is 0

So, (x+2) is one factor.

x^3 + 2x^2 + 4x + 8

=x^2(x+2)+4(x+2)

(x+2)(x^2+4)

Area of shaded region is 18π square unit

Step-by-step explanation:

Please mark brainliest

Answer:

18π cm²

Step-by-step explanation:

The shaded region is calculated as

A = area of circle × fraction of circle

   = πr² × [tex]\frac{80}{360}[/tex] ( r is the radius of the circle )

   = π × 9² × [tex]\frac{2}{9}[/tex]

   = 81π × [tex]\frac{2}{9}[/tex]

   = 9π × 2

   = 18π cm²

Answer:

59

Step-by-step explanation:

Given

f(x) = 2x² + 9

f ( -5) = 2 * ( -5)² + 9

= 25 * 2 + 9

= 50 + 9

= 59

════════ ∘◦❁◦∘ ════════

════════════════════

f(x) = 2x² + 9

════════════════════

f(-5) = ?

════════════════════

#as you the x inside the (x) changed into (-5) it means that you need to change the x into -5.

f(-5) = 2(-5)² + 9

= 2 × 25 + 9

= 50 + 9 = 59

#So f(-5) = 59

Step-by-step explanation:

7 hr/3 pumps

So first we want to find the unit rate which would be...

5.25 hr/1 pump

Now that we found the unit rate we are going to multiply it by 2 because there are 2 pumps...

5.25*2=10.5

So our answer is 10.5 hr/ 2 pumps
