To sketch the graph of the function with an inequality. First is to analyze the different inequality.
If f(0) = 0 the line is in the center of the graph in the origin.,
if f(x)<0 the line is decreasing
if f(x)>0 the line is increasing.

Answer:

185.04 mm

Step-by-step explanation:

The perimeter is 1/2 of the circumference plus the diameter

We need to go around the semicircle on the outside plus across the middle

1/2 C + d

1/2 2*pi * r + 2r

pi *r +2r

Harry solves the equation 1/3t = 15. He says the solution is 30. Is his answer correct? Fill in the blanks to explain how Harry

aksik [14]

Harry can first substitute 30 for t

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10

Since, 10 is not equal to 15, Harry's solution is not correct.

<em><u>Solution:</u></em>

Given that,

Harry solves the equation:

$\frac{1}{3}t = 15$

He says the solution is 30

We have to check if his answer is correct or not

<em><u>Fill in the blanks to explain how Harry can check whether his solution is correct</u></em>

Harry can first substitute 30 for t

$\frac{1}{3} \times 30 = 15$

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10

$10\neq 15$

Since, 10 is not equal to 15, Harry's solution is not correct

<em><u>Correct solution:</u></em>

$\frac{1}{3}t = 15\\\\t = 15 \times 3\\\\t = 45$

Thus correct solution is 45

taurus [48]

Answer:

117

Step-by-step explanation:

-3 + m /9 = 10

-3 + m/9 = 10

m/9 = 10 + 3

m/9 = 13

m/9×9 = 13 × 9

m = 117

A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 14 feet mo

umka21 [38]

Answer:

The dimensions of triangle are 66 ft, 33 ft and 47 ft

Step-by-step explanation:

Let

x -----> the length of one side

y -----> the length of the shortest side

z -----> the length of the third side

we know that

The perimeter of triangle is

$P=x+y+z$

$P=146\ ft$

so

$146=x+y+z$ -----> equation A

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

$z=y+14$ ----> equation C

Substitute equation B and C in equation A and solve for y

$146=2y+y+y+14$

$146=4y+14$

$4y=146-14$

$4y=132$

$y=33\ ft$

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

$x=2(33)=66\ ft$

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

$z=33+14=47\ ft$

therefore

The dimensions of triangle are 66 ft, 33 ft and 47 ft
