Answer:

Tim will get £ 8

Sam will get £ 32

Solution,

let the ratios be x and 4x

 $x + 4x = 40 \\ or \: 5x = 40 \\ or \: x = \frac{40}{5} \\ x = 8 \\ replacing \: value \\ 4x \\ = 4 \times x \\ = 4 \times 8 \\ = 32$ 

hope this helps...

Good luck on your assignment...

<h3>Answer:</h3><h3>Tim = £ 8</h3><h3>Sam = £ 32</h3>

Step-by-step explanation:

$Tim= 1\\Sam = 4\\Total-amount = 4\\1+4=5\\Tim = \frac{1}{5} *40\\Tim = £8\\\\Sam =\frac{4}{5} *40\\sam = £32$

Can someone help me with this math problem ?? Pls it’s for my final !

Airida [17]

Answer:

221.87 feet

Step-by-step explanation:

Given that,

A 525 ft cable runs from the top of an antenna to the ground.

The angle of elevation made by the ground to the top of an antena 25°

We need to find the height of the antenna.

Using trigonometry,

Hypotenuse, H = 525 ft

θ = 25°

So,

$\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft$

So, the height of the antenna is equal to 221.87 feet.

Find the mean and median of the number

Yakvenalex [24]

Answer:

Mean Is 3 , Median Is 3

Step-by-step explanation:

The mean is the usual average, so I'll add and then divide:

0 + 1 + 2 + 3 + 4 + 5 + 6 = 21 divide by 7 you'll get 3

The median is the middle value, so first you'll have to rewrite the list in numerical order: There are seven numbers in the list, so the middle one will be the answer which is 3

0 , 1 , 2 , 3 , 4 , 5 , 6

Simplify this algebraic expression x-5/5+10 А. x+ 11 в. х- 9 c. х- з d. x+9

bulgar [2K]

Answer:

$\displaystyle X+9$

Step-by-step explanation:

$\displaystyle\frac{b}{b}=1$

$\displaystyle\frac{5\div5}{5\div5}=\frac{1}{1}=1$

$\displaystyle x-1=10$

Add and subtract numbers from left to right.

$-1+10=9$

$\displaystyle x+9$ , which is our answer.

Hope this helps!

Annabelle arranged her 42 building blocks into 3 rows of 14 blocks. Then, she rearranged them into 6 rows of 7 blocks. What two

cupoosta [38]

Answer:

21 rows 2 blocks

1 row 42 blocks

Step-by-step explanation:

Given that:

Number of blocks with Annabelle = 42

First arrangement = 3 rows 14 blocks

Second arrangement = 6 rows 7 blocks

To find:

The other two factor pairs that could be used to rearrange the blocks again?

Solution:

Here, we will have to find the factor pairs of total number of blocks present with Annabelle.

i.e. 42

First of all, let us have a look at the factor pairs of 42.

$42 = 3\times 14\\42 = 6\times 7\\42 = \underline{2\times 21}\\42 = \underline{1\times 42}$

Therefore, the other two factor pairs can be 2, 21 and 1, 42.

The other two possible factor pairs are:

21 rows 2 blocks

1 row 42 blocks
