Find the value of cos 0 , If sec 0 = 3/2 0 < 90

Answer: B, E

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

Sum of the first five numbers = 40

The sum of the six numbers should equal 9 x 6 = 54

So, you would do 54 - 40 = 14

Hope that helps! :)

Given:

Sum of ages of brother and sister = 15

Product of their ages = 54

To find:

How old is the older one between the two of them?

Solution:

Let x be the age of brother and y be the age of sister.

Sum of ages of brother and sister = 15

[tex]x+y=15[/tex]

[tex]x=15-y[/tex]                ...(i)

Product of their ages = 54

[tex]xy=54[/tex]

[tex](15-y)y=54[/tex]                [Using (i)]

[tex]15y-y^2=54[/tex]

[tex]0=54-15y+y^2[/tex]

Splitting the middle term, we get

[tex]54-15y+y^2=0[/tex]

[tex]54-9y-6y+y^2=0[/tex]

[tex]9(6-y)-y(6-y)=0[/tex]

[tex](6-y)(9-y)=0[/tex]

Using zero product property, we get

[tex](6-y)=0\text{ and }(9-y)=0[/tex]

[tex]y=6\text{ and }y=9[/tex]

If [tex]y=6[/tex], then using (i), we get

[tex]x=15-6[/tex]

[tex]x=9[/tex]

If [tex]y=9[/tex], then using (i), we get

[tex]x=15-9[/tex]

[tex]x=6[/tex]

Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.

Step-by-step explanation:

r = √(384/96) = √4 = 2

so, a1 = 96/ (2)⁴ = 96/16 = 6

Answer:

70 km/h

Step-by-step explanation:

Answer:

725.7 m²

Step-by-step explanation:

A=2πrh

r=16 1/2 ÷ 2 = 8 1/4

A= 2π(8.25)(14)=725.7

Answer:

The value of 1 tenth is less than the value of 1 ten.

Step-by-step explanation:

Answer:

Because 3 x 1/10 = 3/10

whereas 3 x 10 = 30

and 3/10 < 30

Also b/c 1/10 < 10 and they are multiplied by the same value (3)

Step-by-step explanation:

Answer:they have eaten 3/4 of the total pizza

Step-by-step explanation:

Let the whole pizza =1whole

Amount eaten by Toby =1/2

Amount eaten by Ahmed =1/4

Total Amount eaten by both of them =1/2 +1/4 =  2+1/ 4=3/4

Therefore, they have eaten 3/4 of the total pizza

3 because 2 of them played during spring and winter. 6 of them played during spring and fall. and 13 played during fall and winter. but your asking for year round which is all three seasons meaning only 3 played year round.

Answer:

answer: 50%

Step-by-step explanation:

The answer is 50% because 15 is half of 30 because 15 + 15 = 30 so 15 is half of 30 50%

Answer:

8.99 + 12.50x < 55 and x = 3

Answer:

Step-by-step explanation:

From late 2010, Kim Jong-un was viewed as successor to the leadership of North Korea. Following the elder Kim's death in December 2011, state television announced him as the "Great Successor". Kim holds the titles of General Secretary of the Workers' Party of Korea,[7] Chairman of the Central Military Commission, and President of the State Affairs Commission. He is also a member of the Presidium of the Politburo of the Workers' Party of Korea, the highest decision-making body. In July 2012, Kim was promoted to the highest rank of Marshal in the Korean People's Army, consolidating his position as Supreme Commander of the Armed Forces. North Korean state media often refers to him as "the Marshal" or "Dear Respected Leader". He has promoted the policy of byungjin, similar to Kim Il-Sung's policy from the 1960s, referring to the simultaneous development of both the economy and the country's nuclear weapons program.

Answer:

we have

diameter {d}=6.8m

radius (r)=3.4m

height]h}=8.5

now

volume of cylinder=πr²h=π([6.8]/2)²×8.5=

π(3.4)²(8.5) is your answer

Step-by-step explanation:

Diameter of the cylinder=6.8m

Radius=Diameter/2=6.8/2=3.4

[tex]\boxed{\sf Volume=\pi r^2h}[/tex]

[tex]\\ \tt \mapsto \:Volume_{(Cylinder)}=\pi(3.4)^2\times 8.5 units^3[/tex]

Answer: Reflection about x-axis

Step-by-step explanation:

Given

Initially, vertices are [tex]A(-2,0), B(2,5),C(3,1)[/tex]

After reflection they become [tex]A(-2,0),B(2,-5),C(3,-1)[/tex]

It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.

For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).

So, here reflection is being done about the x-axis.

Answer: You are correct. The mode is between 90 and 100

This is because the tallest bar corresponds to this interval. The mode is the most frequent value.

Answer:

one board game cost 15 dollars

75/5=15

15y

y = number of board games and 15= the price of each board game

so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.
