Find the value of z. round to the nearest hundredth

Mathematics

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

\frac{30}{14}  =  \frac{z}{30}

Multiply both sides by 30;

30 \times  \frac{30}{14}  =  \frac{z}{30}  \times 30

Simplify

z =  \frac{900}{14}

z = 64.28571429

We correct to the nearest hundredthth to obtain,

z = 64.29

The correct choice is C.

Without sketching the graph solve -6-x>10
kompoz [17]

Answer:

x < -16

Step-by-step explanation:

-6-x>10

adding 6 in both sides:

-6-x+6 > 10+6

-x > 16

If you want to remove the negative sign from x, you'll have to change the inequality sign.

x < - 16

Hope this helps.

100 POINTS!!!!

<em>There is no specific requirement in the question, but I'm assuming you need to compute the time needed for Alexis reach 1,000,000 Instagram followers</em>

Answer:

t= 462.82\ days

Step-by-step explanation:

<u>Exponential Growth </u>

When the number of observed elements grows as the previous value multiplied by a constant ratio, we have exponential growth. The formula to model such situations is

\displaystyle f(x) = f_o(1 + r)^t

Where f_o is the initial value of f, 1 + r is the constant ratio, and t is the time expressed in half days (12 hours)

The initial value is 100 Instant followers, thus:

\displaystyle f(x) = 100(1.01)^t

We need to know when the number of followers will reach 1,000,000. Setting up the equation

\displaystyle 100(1.01)^t=1,000,000

Simplifying by 100

\displaystyle (1.01)^t=10,000

Taking logarithms

\displaystyle t\ log(1.01)=log\ 10,000

\displaystyle t\ log(1.01)=4

Solving for t

\displaystyle t=\frac{4}{log(1.01)}=925.63 periods of 12 hrs

t= 462.82\ days

If x and y are integers, and 3x + 2y = 13, which of the following could be the value of y ?
lions [1.4K]
They are all integers so...
first lets substitute
A.3x=13
X=13/3
b.3x+2=13
3x=11
x=11/3
c.3x+4=13
3x=9
x=3
d.3x+6=13
3x=7
x=7/3

E.3x+8=13
3x=5
x=5/3

therefore the possible is letter c because it must be an integer and the definition of integer states that it is not a decimal nor a fraction
