There are three shapes in this composite shape. Area of a square/rectangle is length x breadth.

A1 : 6 x 7 = 42 (small square)

A2 : 18 x 10 = 180 (large square)

A3: 15 x 2 = 30 (rectangle)

Add all answers to get 252 m^2 (squared)

Hope this helps!!

Help me please I’m struggling to much

forsale [732]

Answer:

$\frac{16}{5}$ or $3.2$

Step-by-step explanation:

The given triangles are similar, meaning that their corresponding sides are proportional.

The length of DC (I think its D) is 15 and the length of WZ is 3. ZY is in the same place as CE (16). Make a proportional relationship where Δ→Δ:

$\frac{large}{small} =\frac{large}{small}$

$\frac{DC}{WZ}=\frac{CE}{ZY}$

Insert the known values:

$\frac{15}{3}=\frac{16}{x}$

x is the value of ZY. Solve by cross multiplying:

$15(x)=3(16)\\\\15x=48$

Divide both sides by 15:

$\frac{15x}{15} =\frac{48}{15} \\\\x=3.2$

ZY is 3.2.

Is 3584 a term of the series 7+14+28+56........?

MrRa [10]

Answer:

yes it is the 10th term in the series

Step-by-step explanation:

The nth term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 7 and r = $\frac{a_{2} }{a_{1} }$ = $\frac{14}{7}$ = 2 , then

$a_{n}$ = 7 $(2)^{n-1}$

Equate $a_{n}$ to 3584 and solve for n

7 $(2)^{n-1}$ = 3584 ( divide both sides by 7 )

$2^{n-1}$ = 512 , that is

$2^{n-1}$ = $2^{9}$

Since the bases on both sides are equal, both 2 , then equate the exponents

n - 1 = 9 ( add 1 to both sides )

n = 10

3584 is the 10th term in the series

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. Two marbles are chosen from

Kryger [21]

Answer:

The expression would give the probability that one marble is yellow and the other marble is red is,

$P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)$

Step-by-step explanation:

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. So in total there are 25 marbles.

Hence,

Probability of getting yellow ball = $P(Y)=\dfrac{8}{25}$

Probability of getting red ball = $P(R)=\dfrac{5}{25}$

Probability that one marble is yellow and the other marble is red is,

$P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)=\dfrac{8}{25}\cdot \dfrac{5}{25}+\dfrac{5}{25}\cdot \dfrac{8}{25}=0.128$
