Um, you didn't provide anything for me to answer so i don't really know what to provide for you.

Step-by-step explanation:

Answer:

ok so first we know that 1/3 of a hour is 20 minutes since

60*1/3=20

so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15

20*15=300

300 minutes or 5 hours

Hope This Helps!!!

Answer:

5 Hour

Step-by-step explanation:

For 1/15 of lawn it takes = 1/3

So, for entire lawn it will take = 1/3 * 15 = 5

===========================================

Work Shown:

AC/QS = BC/RS

4/10 = m/15

4*15 = 10*m

60 = 10m

10m = 60

m = 60/10

m = 6

The first equation is possible because the triangles are similar. The horizontal sides AC and QS form the ratio AC/QS. This is equal to the ratio of the diagonal sides BC/RS since similar triangles have their sides in proportion.

After the equation is set up, we cross multiply and then solve for m.

Answer:

16x² - 24x + 9

Step-by-step explanation:

One side = (8x-6)÷4

One side = 2x - 3/2

Area = (2x-3/2)(2x-3/2)

Open the brackets

2x(2x-3/2) - 3/2(2x-3/2)

= 16x² - 24x + 9

Answer:

B) 7/25

Step-by-step explanation:

sin M = opposite/hypotenuse = 7/25

Answer:

[tex]\sin B=\displaystyle\frac{b}{c}[/tex]

Step-by-step explanation:

Hi there!

This is the sine ratio:

[tex]\sin\theta=\displaystyle\frac{opposite}{hypotenuse}[/tex] where "opposite" is the side opposite the angle, "hypotenuse" is the hypotenuse of the right triangle and theta is the angle.

To find sin B, we must identify which sides of the triangle are the opposite side and the hypotenuse.

The side opposite to angle B would be b.

The hypotenuse is the side opposite the right angle, and that would be c.

[tex]\sin B=\displaystyle\frac{b}{c}[/tex]

I hope this helps!

Answer:

The choice second

[tex] \sin( B) = \frac{b}{c} [/tex]

Step-by-step explanation:

sin B = opposite/hypotenuse

Answer: 6

Step-by-step explanation:

Since the 3 semicircles are identical, we know that each semicircle has a diameter of 4, meaning they each have a radius of 2.

We can use the fact that (arc length of semicircle) = (pi)(r) to get the arc length of each to be 2pi.

Meaning 2pi + 2pi + 2pi = 6pi.

Answer: 12

Step-by-step explanation:

Distribute the 9(x-11) first. If you distribute it, it becomes 9x-99

9x-99=9

Add 99 to both sides

9x=108

Divide by 9 on both sides

X=12

Hey there!

6/11 = c/11

6(77) = c(11)

6(77) = 11(c)

462 = 11c

We got the new equation above because we had to CROSS MULTIPLY.

11c = 462

DIVIDE 11 to BOTH SIDES

11c/11 = 462/11

CANCEL out: 6/6 because it give you 1

KEEP: 462/11 because it help solve for the c-value

NEW EQUATION: c = 462/11

SIMPLIFY IT!

c = 42

Therefore, your answer is: c = 42

Good luck on your assignment & enjoy your day!

Answer:

The distance is √58

or 7.61577...

Step-by-step explanation:

If you draw a right triangle where the given line is the hypotenuse you can use Pythagorean theorem (a²+b²=c²) to find the length.

It would be 7 units tall and 3 units wide.

7²+3²=49+9=58

The distance is √58

Answer:

y = [tex]\frac{9}{2}[/tex][tex]\sqrt{2}[/tex]

x = 9

Step-by-step explanation:

this triangle is isosceles because the base angles are each 45°

the ratio of sides in a 45-45-90° triangle are 1 : 1 : [tex]\sqrt{2}[/tex]

so 'y' is going to also be [tex]\frac{9}{2}[/tex][tex]\sqrt{2}[/tex]

'x' will be [tex]\sqrt{2}[/tex] multiplied by  [tex]\frac{9}{2}[/tex][tex]\sqrt{2}[/tex] which will be:

[tex]\frac{(9x2)}{2}[/tex] = 9

Answer:

vertex = (- 3, 1 )

Step-by-step explanation:

given a quadratic in standard form

f(x) = ax² + bx + c ( a ≠ 0 )

then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

f(x) = x² + 6x + 10 ← is in standard form

with a = 1, b = 6 , then

x = - [tex]\frac{6}{2}[/tex] = - 3

substitute x = - 3 into f(x) for corresponding y- coordinate

f(- 3) = (- 3)² + 6(- 3) + 10 = 9 - 18 + 10 = 1

vertex = (- 3, 1 )

The cοmplete equatiοn fοr h(x) is h(x)=4

An expοnential functiοn is a mathematical functiοn οf the fοrm f(x) = a^x, where a is a cοnstant and x is the variable. The cοnstant a is called the base οf the expοnential functiοn, and it is typically a pοsitive real number. When a is greater than 1, the functiοn represents expοnential grοwth, while when a is between 0 and 1, the functiοn represents expοnential decay.

Expοnential functiοns have sοme special prοperties, such as the fact that the rate οf change οf the functiοn is prοpοrtiοnal tο its value. In οther wοrds, the larger the value οf the functiοn, the faster it grοws οr decays. Expοnential functiοns alsο have a hοrizοntal asymptοte at y = 0 when a is between 0 and 1, and nο hοrizοntal asymptοte when a is greater than 1.

Expοnential functiοns are widely used in mathematics, science, ecοnοmics, and engineering tο mοdel phenοmena that exhibit expοnential grοwth οr decay, such as pοpulatiοn grοwth, radiοactive decay, and cοmpοund interest. They are alsο used in prοbability theοry tο mοdel the distributiοn οf randοm variables, such as the expοnential distributiοn.

Tο cοmplete the equatiοn fοr h(x), we need tο find the values οf a and b in the expοnential functiοn that cοrrespοnd tο the given table οf values:

x | h(x)

0 | 10

1  | 10

2 | 10

3 | 4

4 | 4

5 | 4

Since the value of h(x) is constant (equal to 10) for x = 0, 1, and 2, we know that  [tex]b^0 = b^1 = b^2 = 1[/tex], which implies that b = 1.

Substituting b = 1 into the exponential function, we have:

[tex]h(x) = a * 1^x = a[/tex]

To find the value of a, we can use any of the given values of h(x) for which x > 2. For example, when x = 3, we have:

h(3) = 4 = a

Therefore, the complete equation for h(x) is:

[tex]h(x) = 4 * 1^x = 4[/tex]
