Answer:

54

Step-by-step explanation:

you could either add 125% and 24 to get 54

or you can figure out that 125% of 24 is 30 and add 24 and 30 together to get 54

Answer:

x = 2√3

Step-by-step explanation:

Reference angle = 30°

Hypotenuse = 4

Adjacent = x

Apply trigonometric function, CAH:

Cos 30 = Adj/Hyp

Cos 30 = x/4

4 × Cos 30 = x

4 × √3/2 = x (cos 30 = √3/2)

2√3 = x

x = 2√3

Answer:

Step-by-step explanation:

well just go throught the factors as far as you can ik from my personal mindset that 14*14= 196 so if i go bk and  calculate 13*13=169 which means its gonna be in between 13 and 14. so to figure this out we have to write it out. so we can try 13.5*13.5=182.25 so we have to go higher  13.89*13.89=192.9321 which means it has to be 13.89 rounded to the nearest hundreth.

Answer:

Step-by-step explanation:

P varies jointly as q and r

p=k* q r

150 =k *(18)(5)

150 = k*(90)

150/90 = k

5/3 = k

find q when p=345 and r =9

p=k* q r

345 = (5/3) * q *9

345 = 45 q / 3

1035 = 45 q

q=23

The required value of the q in the proportionality relationship is given as q = 23.

Given that,

p varies jointly as q and r, and p = 150 when q = 18 and r = 5, find q when p = 345 and r = 9.​

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

P varies jointly as q and r

p =k × q r  - - - - - (1)

150 =k × 18× 5

k = 5 / 3

Put k = 5/3, p = 345 and r = 9 in equation 1

345 = (5/3) × q ×9

q = 23

The required value of the q in the proportionality relationship is given as q = 23.

Answer:

x <-6

Step-by-step explanation:

The mean of the given numbers is 15.

The mean is the mathematical average of a group of integers.

The given numbers are 8, 14, 32, 6, and 15.

There are a total of 5 numbers.

The mean of the number is:

m = ( 8 + 14 + 32 + 6 + 15)/5

m = 15

Hence, the mean of the given numbers is 15.

Answer:

π(6 cm) (10 cm)

Step-by-step explanation:

As we know that

The formula to calculate the lateral surface area of the cone is πrl

where

r denotes the radius i.e. 6 cm

l denotes the length i.e. 10 cm

So based on the above information

The expression that shows the lateral surface area of the cone is

π(6 cm) (10 cm)

Therefore the third option is correct

Hence, the same would be relevant

Answer:

x = -9

Step-by-step explanation:

First,Add 4 to both sides

-4x-4+4=36-4+4

Then,simplify

-4x=36

divide both sides by -4

-4x/-4 = 36/-4

Lastly simplify it to get your answer!

Answer:

The answer is 7x

Step-by-step explanation:

The x is the coefficent and every x has a coefficent  even if it doesn't have  number because the coefficent   represent how many x's there are so it is one x plus 6 x and that equal seven x. The x can be anything but one of something plus 6 equals 7.

Answer:

Step-by-step explanation:

Given,

Dimensions of the rectangular prism = 9ft, 12ft and 4ft

Therefore,

Surface area of the rectangular prism

= 2( lb + bh + lh)

[tex] = 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2} [/tex]

[tex] = 2(108 + 36 + 48) {ft}^{2} [/tex]

[tex] = 2 \times 192 {ft}^{2} [/tex]

[tex] = 384 {ft}^{2} [/tex]

Hence,

Surface area of rectangular prism is 384 sq. ft (Ans)
