Answer:

Solution given:

Since rectangle ABCD is similar rectangle RSTU .Its corresponding side will be proportional.

length AB and ST

breadth AD and SR

$\frac{AB}{AD}=\frac{ST}{SR}$

$\frac{10}{4}={x}{2}$

x= $\frac{10*2}{4}=5$

:.value of x is 5

What is the value of the angle marked with x?

earnstyle [38]

Answer:

97°

Step-by-step explanation:

The sides that are equal are 4.6

One of the sides length is 4.6, and its opposite angle is 97. If there is another line that has a length of 4.6 in the same figure, it's angles should also be 97 degrees.

Ciara Larry and jeeta pick apples at an orchard Ciara pick twice as many pounds is Larry and three times as many pounds as jeeta

steposvetlana [31]

Answer:

The pounds of apples picked by Ciara was 4,560

The pounds of apples picked by Larry was 2,280

The pounds of apples picked by Jeeta was 1,520

Step-by-step explanation:

Let

x -----> pounds of apples picked by Ciara

y ----> pounds of apples picked by Larry

z ----> pounds of apples picked by Jeeta

we know that

$x+y+z=8,360$ ----> equation A

$x=2y$

$y=x/2$ ----> equation B

$x=3z$

$z=x/3$ ----> equation C

substitute equation B and equation C in equation A and solve for x

$x+x/2+x/3=8,360$

Multiply by 6 both sides to remove the fractions

$6x+3x+2x=50,160$

$11x=50,160$

$x=4,560\ lb$

<em>Find the value of y</em>

$y=x/2$ ----> $y=4,560/2=2,280/ lb$

<em>Find the value of z</em>

$z=x/3$ ---> $z=4,560/3=1,520\ lb$

therefore

The pounds of apples picked by Ciara was 4,560

The pounds of apples picked by Larry was 2,280

The pounds of apples picked by Jeeta was 1,520

Factor this expression completely and then place the factors in the proper location. Note: Place factors alphabetically!

Usimov [2.4K]

To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

$mn - 4m - 5n + 20$

2. The first thing you must do to factor the expression is to group the terms, as following:

$(mn-4m)+(-5n+20)$

3. Now, choose the greatest common factor of each group:

$m(n-4)-5(n-4)$

4. Now, you need to factor the expression by factoring out the $n-4$

$(m-5)(n-4)$

The answer is: $(m-5)(n-4)$

I need help. Help me understand this.

Katyanochek1 [597]

First, you square numbers and multiply the exponents.
32^2 is 1024 and 6x2=12
4^2 is 16 and 4x2=8
The equation is now 1024m^12/16n^8
You divide the numbers and get 64
Since the m and n aren’t the same letter, you leave them alone
The answer is 64m^12n^8
