V= 232.4

Step-by-step explanation:

V= 1/3 x 28 x 24.9

Okay so multiple 17 times 8 and 16 times 33 and then add the answers together and you should get 664!

Step-by-step explanation:

here's your solution

=> Firstly divide above picture in two parts

=> 1st = traingle

=> 2nd = trapezium

=> area of traingle = 1/2*base*height

=> height = 8

=> we need to find out base by using Pythagoras formula

=> base^2 = 17^2 - 8^2

=> base^2 = 289 - 64 = 225

=> base = √225

=> base of traingle = 15

=> now, area of traingle = 1/2*15*8

=>60sq.units

=> area of trapezium = 1/2(sum of p. sides ) *

distance between them

=> area = 1/2*(33 + 15)*16

=> area = 1/2*16*48

=> area = 384sq.units

=> area of whole figure = 384 + 60

= 444 sq.units

Answer:

20

Step-by-step explanation:

To solve this problem use proportions. The tree's proportion is equal to [tex]\frac{30}{40}[/tex] and the shed's proportion is [tex]\frac{15}{x}[/tex]. These proportions are made by putting the height of the object over the length of the shadow. Then, cross multiply to find x. Do this by multiplying [tex]30 *x[/tex] and [tex]40*15[/tex]. Next set these equal to each other, [tex]30x=600[/tex]. Finally, divide both sides by 30 to find x. This equals 20 feet.

Answer:

Width = 1/2h

Area = 1/4h²

Step-by-step explanation:

This is quite a vague question from you. Being asked to find the width and area of a particular shape, without being given dimensions.

However, I would try to solve it nonetheless.

From your question, you stated that the width of the rug is half its height, if so, then,

w = 1/2h

Again, you're being asked to find the area. Area of a kite is given as

Area = 1/2 * Width * Height and as such, we have

Area = 1/2 * 1/2h * h

Area = 1/4 * h²

All that you need to do now is substitute the value of h

Answer:

Option A

Step-by-step explanation:

By applying Pythagoras theorem in ΔABC,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

AC² = AB² + BC²

AC² = 6² + 5²

AC = [tex]\sqrt{61}[/tex]

Similarly, by applying Pythagoras theorem in ΔACD,

AD² = AC² + CD²

(10)² = [tex](\sqrt{61})^2[/tex] + x²

x² = 100- 61

x² = 39

x = √(39)

Option A will be the answer.

Answer:

Functions: Second Graph

Not functions: first and third graph

Step-by-step explanation:

The first and third graph are not functions and the second graph is a function. Use the vertical line test. I'm 100% sure.

By the vertical line test, it's clear that graph first will not be a function, second will be a function and third will also not be a function.

A vertical line test is a test to determine whether a given function is a function or not.

In the vertical line test, we draw a vertical line on every x's point if the line intersects with only a single value of corresponding y then it will be a function otherwise not.

In the first given function if we draw a vertical line at x = 2 then it gave different values corresponding to y hence,  it will not a graph.

In the second given function by drawing a vertical line, it gave a single unique value so it will be a function.

In the third given function if we draw a vertical line at x = 1 and 2 then it gives different values corresponding to y hence,  it will not be a graph.

Answer:

320 x 0.08 = X

In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

Step-by-step explanation:

Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:

320 x 0.08 = X

25.6 = X

Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

Answer:

No, it is not a right triangle.

Step-by-step explanation:

First lets define a right triangle.  A right triangle is a triangle with one side that equals 90 degrees.  When we look at 13, 64, and 86, we can see there are no sides that equal 90 degrees.

Answer:

50M

Step-by-step explanation:

The area of a trapezium = 1/2 x ( a + b) x h

a and b are the parallel sides

h = height

300sqm = 0.5 x (10 + b) x 10

divide both sides by 10

30 = 0.5 x  (10 + b)

Divide both sides by 0.5

60 =  (10 + b)

b = 60 - 10 = 50

Answer:

4 times

Step-by-step explanation:

Given that :

Cups of liquid required = 2 2/3

Fraction of liquid cup added per 10 minutes = 2/3

The number of times 2/3 cups of liquid is added :

Total cups of liquid required / amount of liquid added at a time

2 2/3 ÷ 2/3

8/3 ÷ 2/3

8/3 * 3/2

24 / 6

= 4 times

Number one: Just plot down on the number like the numbers you have. Just took the test for this.

Answer:

w = 4.

Step-by-step explanation:

Remove the fractions by multiplying thru by 5:

-2w + 57 = 49

-2w = 49 - 57

-2w = -8

I believe (x+5)(x-2) would be equal though.

Step-by-step explanation:

(x-5)(x+2) = x²+2x-5x-10

simplify:

x²-3x-10 ≠ x²+3x-10

(x)(x+3) = x²+3x

simplify:

x²-3x ≠ x²+3x-10

(x+3)(x-10) = x²-10x+3x-30

simplify:

x²-7x-30 ≠ x²+3x-10

Given:

Consider the given polynomials are:

[tex]f(x)=7x^3+x^2-4x+10[/tex]

[tex]g(x)=x^2-5[/tex]

To find:

The polynomial function rule for [tex]g(x)+f(x)[/tex].

Solution:

We need to add both functions to get [tex]g(x)+f(x)[/tex].

[tex]g(x)+f(x)=(x^2-5)+(7x^3+x^2-4x+10)[/tex]

[tex]g(x)+f(x)=x^2-5+7x^3+x^2-4x+10[/tex]

On combining like terms, we get

[tex]g(x)+f(x)=7x^3+(x^2+x^2)-4x+(10-5)[/tex]

[tex]g(x)+f(x)=7x^3+2x^2-4x+5[/tex]

Therefore, the required function is [tex]g(x)+f(x)=7x^3+2x^2-4x+5[/tex].

Answer:

i. 1.63 s

ii. The negative time cannot be used in this context

Step-by-step explanation:

i. Since  h = −640t² and the rocket descends 1,690 m, h = -1,690 m (since there is a drop in height).

So,  h = -640t²

t² = h/-640

t = √(- h/640)

Substituting h into the equation, we have

t = √(- h/640)

t = √[-(-1,690)/640]

t = √2.640625

t = 1.625

t ≈ 1.63 s

ii. So, the negative time cannot be used in this context because, the height drop is negative.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The decimal form of 1/3 is a repeating decimal.

Now,

Since, The decimal form of 1/3 is a repeating decimal.

As, 1 / 3 = 0.33333...

And, Some of the multiples of 1/3 are;

1 / 3 = 1×2 / 3×2

      = 2 / 6

      = 0.33333....

And, 1 / 3 = 1×3 / 3×3

      = 3 / 9

      = 0.33333....

1 / 3 = 1×4 / 3×4

      = 4 / 12

      = 0.33333....

Thus, Yes, All the multiples of 1/3 also repeating decimals.

Given:

The graph of a parabola.

To find:

The equation for the parabola.

Solution:

The vertex form of a parabola is:

[tex]y=a(x-h)^2+k[/tex]       ...(i)

Where, a is a constant and (h,k) is the vertex.

From the given graph it is clear that the vertex of the parabola is at point (-1,6). So, h=-1 and k=6.

Putting h=-1 and k=6 in (i), we get

[tex]y=a(x-(-1))^2+(6)[/tex]

[tex]y=a(x+1)^2+6[/tex]         ...(ii)

The y-intercept of the graph is at point (0,3). Putting x=0 and y=3 in (ii), we get

[tex]3=a(0+1)^2+6[/tex]

[tex]3-6=a[/tex]

[tex]-3=a[/tex]

Putting a=-3 in (ii), we get

[tex]y=-3(x+1)^2+6[/tex]

Therefore, the equation of the parabola is [tex]y=-3(x+1)^2+6[/tex].
