Q square has the perimiter of 38 inches. we want to know the length of each side

1 answer:

4 0

A square has 4 equal sides. This means that the formula for the perimeter is 4s = P, or the product of 4 times one side length is equivalent to the perimeter. With this information, we are now ready to move onto the next step. Let's set up an equation to solve for the length of each side.
4S = P;
4S = 38.
Now we are ready to solve. As we want to isolate our variable, S, we must divide both sides by 4 (remember that what you do to one side of the equation, you must do to the other).
4S / 4 = S
38 / 4 = 9.5

We are now left with the remaining solution:
S = 9.5.

The length of each side is 9.5 inches.

I hope this helps!

The sample space of a random experiment is {a,b,c,d,e} with probabilities 0.1,0.1,0.2,0.4, and 0.2, respectively. Let A denote t

velikii [3]

Answer with Step-by-step explanation:

We are given that a sample space

S={a,b,c,d,e}

P(a)=0.1

P(b)=0.1

P(c)=0.2

P(d)=0.4

P(e)=0.2

a.A={a,b,c}

P(A)=P(a)+P(b)+P(c)

P(A)=0.1+0.1+0.2=0.4

b.B={c,d,e}

P(B)=P(c)+P(d)+P(e)=0.2+0.4+0.2=0.8

c.A'=Sample space-A={a,b,c,d,e}-{a,b,c}={d,e}

P(A')=P(d)+P(e)=0.4+0.2=0.6

d. $A\cup B$ ={a,b,c,d,e}

$P(A\cup B)$ =P(a)+P(b)+P(c)+P(d)+P(e)=0.1+0.1+0.2+0.4+0.2=1

e. $A\cap B$ ={c}

$P(A\cap B)=P(c)=0.2$

Antonio wants to invest $7600 in a saving account. Determine the interest rate (simple interest) required for Antonio’s investme

disa [49]

<h3>Interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum</h3>

Solution:

Given that,

Antonio wants to invest $7600 in a saving account

Antonio’s investment to double in value in 12 years

To find: Rate of interest

The total amount using simple interest is given as:

$A = p(1+\frac{r}{100}t)$

Where,

p is the principal

r is the rate of interest

t is the number of years

From given,

p = 7600

t = 12 years

r = ?

Antonio’s investment to double

Therefore,

A = 2(7600) = 15200

Substituting the values we get,

$15200 = 7600(1 + \frac{r}{100} \times 12)\\\\\frac{15200}{7600} = 1 + 0.12r\\\\2 = 1 + 0.12r\\\\0.12r = 2 - 1\\\\0.12r = 1\\\\r = 8.333 \%$

$r \approx 8.3 \%$

Thus interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum

Find B Plzz find the right answer and don’t just guess

LenaWriter [7]

Answer:

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

B^2 + 8^2 = 15^2

B^2 + 64 + 225

B^2 = 225 - 64

B^2 = 161

B = $\sqrt{161}$ OR 12.7
