Answer:

$86

Step-by-step explanation:

8 hours times 10.75

Answer: $86.00

Step-by-step explanation:

8 to 9 , 9 to 10, 10 to 11, 11 to 12, 12 to 1 , 1 to 2, 2 to 3 , 3 to 4 come up to 8 hours.

4:00 to 4: 30 is half hour.

So 8:00 to 4: 30 come up to 8 1/2 hours (eight and half hours ).

8:30 am to 4:30 pm= 8 hours.

then it is $10.75x8=$86.00

Answer:

Try to say 1/3 of 5/8 and simplify then you should get an answer in  I believe

Step-by-step explanation:

The function that models the relationships among x, y, and r is [tex]r=\sqrt{x^2+y^2}[/tex]

"It is a triangle having one of the angle measures 90° "

"It is the longest side of the right triangle."

"For a right triangle,

[tex]a^2+b^2=c^2[/tex], where c is the hypotenuse of the right triangle and a, b are other two sides of right triangle."

For given question,

We need to write a function that models the relationships among x, y, and r.

Consider a right triangle ABC.

where AB = x, BC = y and hypotenuse AC = r

Using Pythagoras theorem,

[tex]x^{2} + y^{2} =r^{2}[/tex]

above function defines the relationships among x, y, and r.

Now we solve above equation for 'r',

[tex]\Rightarrow r^2=x^2+y^2\\\\\Rightarrow r=\sqrt{x^2+y^2}[/tex]

Therefore, the function that models the relationships among x, y, and r is [tex]r=\sqrt{x^2+y^2}[/tex]

Answer:

Look below!

Step-by-step explanation:

1. What is the horizontal distance that your bridge must span to clear the ravine? (1 point)

150 feet.

2. Write a function that models the relationships among x, y, and r. (Hint: Use the Pythagorean theorem.) Then solve the equation for r in terms of x and y. (3 points: 1 point for the correct Pythagorean setup, 1 point for work, 1 point for the solution)

Pythagorean theorem—>a^2+b^2=c^2

a and b are the legs, while c is the hypotenuse.

x^2+y^2=r^2

Take the root of both sides

r=√x^2+y^2

Answer:

382 cm²

Step-by-step explanation:

The shape can be decomposed into two rectangular prism or cuboids

✔️Dimension of prism 1 (smaller prism):

L = 10 cm

W = 3 cm

H = 7 - 4 = 3 cm

Surface area of prism 1 = 2(LW + LH + WH)

= 2(10*3 + 10*3 + 3*3)

= 2(69)

Surface area of prism 1 = 138 cm²

✔️Dimension of prism 2 (larger prism):

L = 10 cm

W = 8 cm

H = 4 cm

Surface area of prism = 2(LW + LH + WH)

= 2(10*8 + 10*4 + 8*4)

= 2(152)

Surface area of prism 2 = 304 cm²

✅Surface Area of the composite shape = (Surface area of prism 1 + surface area of prism 2) - (2 × area of the base of prism 1)

= (138 + 304) - (2 × L × W)

= 442 - (2 × 10 × 3)

= 442 - 60

= 382 cm²

Answer:

The is A) 91

Step-by-step explanation:

Answer:

[tex]3a + b = 14[/tex]

[tex]b = 4a[/tex]

Step-by-step explanation:

Key:

a = 3 point throws

b = Free throws

Total points = 14

Required

Determine the system of equations

[tex]Total\ points = 14[/tex] implies that:

[tex]3 * a + b = 14[/tex]

[tex]3a + b = 14[/tex]

4 times as many b as a implies that:

[tex]b = 4 * a[/tex]

[tex]b = 4a[/tex]

So, the system of equations are:

[tex]3a + b = 14[/tex]

[tex]b = 4a[/tex]

just here for the points :l

Answer:

100

First, add 7 to both sides of the equation so it would be;

2−7=−5+14

2−7 + 7=−5+14+7

To simplify this it would be:

2=−5+21

Add 5 to both sides, it would look like this:

2=−5+212+5=−5+21+5

To simplify it would be;

7=21

Divide both sides of equation with once again, the same number

7=21  77=217

Simplify it;

=3

Therefore your answer is;

=3

Answer:

The graph for y=[tex]\sqrt{x}[/tex]+1 looks like this. Hope this helped you :D

Step-by-step explanation:

The required graph of y = √x + 1 is a curve that starts from the point (0,1) and rises continuously as x increases.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The equation y = √x + 1 represents a simple algebraic function in which the value of y is dependent on the value of x.

When we plot this function on a graph with x on the horizontal axis and y on the vertical axis, we get a curve that starts from the point (0,1) and continues upward as x increases.

At x=0, the value of y is 1. As x increases, the value of y increases as well, but at a slower rate because of the square root function. As x approaches infinity, the value of y also approaches infinity, but again at a slower rate than a linear function.

Since the domain of the function is all non-negative real numbers (x ≥ 0), the graph of the function exists only in the first quadrant of the coordinate plane.

Overall, the graph of y = √x + 1 is a curve that starts from the point (0,1) and rises continuously as x increases.

Answer: No it can't

You can prove this with Pythagorean theorem. (a^2+b^2=c^2) In this case, 6 is the highest number so we know it has to be the hypotenuse. So plug it into the equation, 1^2+1^2=6^2, and simplify. You will get 2=36, and we know that is not true, so a triangle can't have the lengths of 1, 1, and 6.

1. H+S=40

2. 19H+25S=922

From 1,

19H+19S=760

Subtract this from 2 to eliminate H,

19H+25S-19H-19S=922-760

6S=162

Solve for S, then use either equation to solve for H.

Answer:

height be 4 in

length be 9 in

ANd, the width be 7 in

Step-by-step explanation:

Let us assume the height of the box be x

So the length would be 2x + 1

And, the width be x + 3

As we know that

The volume of the rectangular box = length × width × height

252 = (2x + 1) × (x + 3) × (x)

252 = (2x^2 + x) × (x + 3)

252 = 2x^3 + 6x^2 + x^2 + 3x

2x^3 + 7x^2 + 3x = 252

2x^3 + 7x^2 + 3x - 252 = 0

after solving this

x = 4

So height be 4 in

length be 9 in

ANd, the width be 7 in

Answer :

to find area of the square = 6 to the power 2

to find the area of the rectangle = (5x + 12) * 5x

therefore,

square's area = 36

rectangle's area = 5x*5x + 12 * 5x

= 25x * 60x

Now we have to find the sum of both the areas,

so, 36 + 1500 = 1536
