Answer:

AS IT IS RIGHT ANGLE .

THEREFORE, 1 ANGLE =90°

A=55°,

LET LAST ANGLE BE Y.

THEREFORE, Y=90-55=35°

RATIO OF A:Y=55:35=11/7

RATIO OF ANÔTHER SIDE :X=11:7

HYPOTENOUES=8

THEREFORE8^2=11X^2+7X^2

64=121X^2+49X

A torch and a battery cost £2.50 altogether. The torch costs £2.00 more than the battery.

Genrish500 [490]

Answer:

$\frac{1}{10}$

Step-by-step explanation:

Let $t$ represent the cost of the torch and $b$ represent the cost of the battery.

The torch and a battery cost £2.50 altogether.

$\Rightarrow t+b=2.50$

The torch costs £2.00 more than the battery.

$\Rightarrow t=b+2.00$

We substitute the second equation into the first equation to get;

$\Rightarrow b+2.00+b=2.50$

$\Rightarrow 2b=2.50-2.00$

£2.50

$\Rightarrow 2b=0.50$

$\Rightarrow b=0.25$

The price of the battery is £0.25

We express this as a fraction of the total cost which is £2.50 to get;

$\frac{0.25}{2.5}=\frac{1}{10}$

Suppose Cesar Chavez lead a March with 6,300 people. If the ratio of marchers who were not farmworkers to farmworkers is 4:5, ho

baherus [9]

Answer:

3500.

Step-by-step explanation:

We have been given that Cesar Chavez lead a March with 6,300 people. The ratio of marchers who were not farm-workers to farm-workers is 4:5. We are asked to find the number of marchers, who were farm-workers.

First of all, we will find the ratio of farm-workers to total marchers as:

$\frac{\text{Farm-workers}}{\text{Total marchers}}=\frac{\text{Farm-workers}}{\text{Farm-workers+non-farm-workers}}=\frac{5}{4+5}=\frac{5}{9}$

To find the number of marchers, who were farm-workers, we need to find $\frac{5}{9}$ of whole marchers.

$\text{Number of marchers that were farm-workers}=6300\times \frac{5}{9}$

$\text{Number of marchers that were farm-workers}=700\times \frac{5}{1}$

$\text{Number of marchers that were farm-workers}=3500$

Therefore, 3500 marchers were farmers.

What is the measure of angle X ?

Rus_ich [418]

Answer:

65 deg

Step-by-step explanation:

Recall that interior angles of a triangle must add up to 180 deg.

hence

x + 68 + 47 = 180

x = 180 - 68 - 47 = 65 deg

A above ground garden is rectangular and has a length of 15 feet and a height of 2 feet. It will hold 375 cubic feet of soil. Wh

Fittoniya [83]

Answer: $12.5\ ft$

Step-by-step explanation:

Given

Length L=15 feet

width b=2 feet

Volume V=375 cubic feet

Suppose h is the height

Volume is given by $V=l\times b\times h$

$\Rightarrow 375=15\times 2\times h\\\Rightarrow h=\frac{375}{30}=12.5\ ft$
