HURRY ILL GIVE U BRAINLIEST!!! Find the area of each figure. Which do these belong in?

nordsb [41]

Answer:

Area of rectangle PQRS is 14 square units.

Area of triangles UVW and EFG and square ABCD are 16 square units each.

Step-by-step explanation:

Let us find the area of each of the figures shown in the graph.

Area of rectangle PQRS is given as the product of PQ and QS.

From the graph,

Length of PQ = 7 units

Length of QS = 2 units

Now, area of rectangle PQRS = $PQ\times QS=7\times 2=14$ square units.

Now, area of square ABCD is given as the square of any of its side.

From the graph, AB = 4 units.

So, area of ABCD = $AB^{2}=4^2=16$ square units.

Area of triangle UVW is given as the half of the product of its base VW and height UW.

From the graph, UW = 4 units, VW = 8 units

Therefore, area of triangle UVW = $\frac{1}{2}\times UW\times VW=\frac{1}{2}\times 4\times 8=16$ square units.

For triangle EFG, EF = 4 units and FG = 8 units.

Area = $\frac{1}{2}\times EF\times FG=\frac{1}{2}\times 4\times 8=16$ square units.

Area of rectangle PQRS is 14 square units. The remaining figures have areas each equal to 16 square units.

Find the values of x, y, and z in the triangle to the right. A triangle has angles labeled as follows: lower left, x degrees; t

Studentka2010 [4]

Given:

Consider the below figure attached with this question.

Angles of a triangle are x, y and z.

To find:

The values of x, y and z.

Solution:

If two angles are linear pair, then their sum is 180 degrees.

$y+(3x+5)=180$

$y=180-3x-5$

$y=175-3x$

Similarly,

$z+(3x-5)=180$

$z=180-3x+5$

$z=185-3x$

According the the angle sum property, the sum of all angles of a triangle is 180 degrees.

$x+y+z=180$

$x+(175-3x)+(185-3x)=180$

$-5x+360=180$

$-5x=180-360$

$-5x=-180$

Divide both sides by -5.

$x=36$

The value of x is 36.

$y=175-3(36)$

$y=175-(108)$

$y=67$

Now,

$z=185-3(36)$

$z=185-108$

$z=77$

Therefore, the values of x, y and z are 36, 67 and 77 respectively.

A coin is tossed 20 times. It lands on heads 9 times. What is the P(H) according to your experiment? Write your answer as a frac

Mama L [17]

Answer:

$\frac{9}{20}=0.45=45$ %

Step-by-step explanation:

Probability is found by first forming a fraction where the numerator represents the number of desired outcomes and the denominator represents the total number of outcomes. In this case, the desired outcomes is the amount of times the coin lands on heads (9) and the total outcomes is the number of times the coin is tossed (20):

$\frac{9}{20}$

Divide numerator by denominator to get a decimal: 9÷20= 0.45

Multiply the decimal by 100 to get a percent: 0.45 x 100 = 45%
