Answer:

B   -------   DE ≅ RS

it's B because DE and RS both contain the equal angles.

Answer:

[tex]h(t) = 10 + 5t[/tex]

70 feet

Your height in 5 seconds is 35 feet

Step-by-step explanation:

From the question, we understand that:

[tex]Initial\ Height = 10[/tex]

[tex]Rate = 5[/tex] per second

Solving (a): Equation for h(t)

This implies that the height at t seconds and is calculated as thus:

[tex]h(t) = Initial\ Height + Rate * t[/tex]

Where t represents seconds

Substitute values for Initial Height and Rate

[tex]h(t) = 10 + 5* t[/tex]

[tex]h(t) = 10 + 5t[/tex]

Solving (b): Height in 12 seconds

This implies that:

[tex]t = 12[/tex]

Substitute 12 for t in [tex]h(t) = 10 + 5t[/tex]

[tex]h(12) = 10 + 5 * 12[/tex]

[tex]h(12) = 10 + 60[/tex]

[tex]h(12) = 70[/tex]

Hence, your height will be 70 feet

Solving (c): h(5) = 35 means?

Using the illustration in (b) above;

This means that your height in 5 seconds is 35 feet

Answer:

14

f(x) = 7

-7^2 + 9(7)= -49 + 63 = 14

Answer: The length of JF = 16 units.

Step-by-step explanation:

Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.

i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]

If  EJ is 3y-8 and JF is 7y-40.

Then, [tex]3y-8=7y-40[/tex]

[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]

JF= 7(8)-40 =56-40= 16 units

Hence, the length of JF = 16 units.

Answer:

2.5

Step-by-step explanation:

Given:

The inequality is

[tex]2n+8>12[/tex]

To find:

The solution of the given inequality.

Solution:

We have,

[tex]2n+8>12[/tex]

Subtract 8 from both sides.

[tex]2n+8-8>12-8[/tex]

[tex]2n>4[/tex]

Divide both sides by 2.

[tex]\dfrac{2n}{2}>\dfrac{4}{2}[/tex]

[tex]n>2[/tex]

It means, the value of n is greater than 2.

Therefore, the solution of given inequality is n > 2.

(14-7×7)16

(14-49)16

(-35)16

-560

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.

A = 16/4 marked blocks = 25%

B = 16/8 marked blocks = 50%

C = 16/6 marked blocks = ?

D = 16/10 marked blocks = 62,5%

So answer would be A

Answer:

x = 6

y = [tex]3\sqrt{2}[/tex]

Step-by-step explanation:

Thats a 45 45 90 triangle, one of my favorite and you'll come to miss it later because of how easy it is.

See the file provided for the trick

Because [tex]3\sqrt{2}[/tex] falls where a 1 is in the diagram that means y is also [tex]3\sqrt{2}[/tex] because you multiply [tex]3\sqrt{2}[/tex] by 1, and to get x you'll multiply the value we're given, [tex]3\sqrt{2}[/tex], by the value in the spot in the given diagram, [tex]\sqrt{2}[/tex].

[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex]

Note; a radical multiplied by itself is the value in the radical

Therefore,

[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex] = 3(2) = 6

Thus x = 6

The explanation for this;

[tex]\sqrt{2}[/tex] * [tex]\sqrt{2}[/tex] = [tex]\sqrt{2}^2[/tex]

And if you square a square root you have its square root times its square root squared, which if it was [tex]\sqrt{4}^2[/tex] it'd ultimately be [tex](2)^2[/tex] which is 2x2 which equals 4

Answer:

Quadrilaterial 1

Step-by-step explanation:

Answer:

The width is 20.625 and the length is 19.375

Step-by-step explanation:

Let 2 1/2 + w = length

Let w = width

Equation:

2 1/2 + w + w = 80                     Combine liked terms

2 1/2 + 2w = 80                    

-2 1/2         -2 1/2                        Subtract 2 1/2 from both sides

2w  =   77.5

÷ 2     ÷ 2                                    Divide 2 from both sides

w = 41.25

Length:

2 1/2 + 41.25 = 165/4 or 38.75

Width:

41.25

41.25/2 = 20.625

38.75/2 = 19.375

Answer:

Step-by-step explanation:

  Step one:

Given that membership is $9 and the cost per visit is $1

let the number of visits be x

and the total cost be y

the total cost  for the situation is modeled as

y=mx+c-----equation of a line

   Step two:

given that x=23, we can solve for the totals cost as

by substituting we have

y=1*23+9

y=23+9

y=32

The total cost for 23 visits is $32
