Answer:

1. x > 17

Step-by-step explanation:

When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than

Immediately we can eliminate number 3 and 4

When the line is going in the direction of the right than the inequality sign will face the variable (x)

the numbers are getting larger meaning that x is greater than the constant (17)

Hence, your answer is x > 17

Extra notes:

when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to

Step-by-step explanation:

Use TOA. (tan angle = opposite/adjacent)

Given angle A = 58

adjacent = 6 mi

[tex] \tan(a) = \frac{opposite}{adjacent} \\ \tan(58) = \frac{bc}{6} \\ bc = 6 \tan(58) \\ = 9.6mi(nearest \: tenth)[/tex]

Answer:

Friday

Step-by-step explanation:

Thursday 7/2 ÷ 4 = 7/8 inches an hour (.875)

Friday 8 ÷ 9 = 8/9 inches an hour (.888)

Friday it was snowing faster

Answer:

Friday

if Thursday snowed 3½ inch 4 hours

then for Friday

9 ÷ 8 = 1.125 inches for one hour

1.125 × 4 = 4.5 inches for 4 hours

1.25 inches more than Thursday. So, the answer is Friday ^^

Given:

The figure of a triangle RST on a coordinate plane.

To find:

The perimeter of the triangle RST.

Solution:

From the given graph it is clear that the vertices of the given triangle are R(-2,7), S(-5,1) and T(-7,-5).

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the distance formula, we get

[tex]RS=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-7\right)^2}[/tex]

[tex]RS=\sqrt{\left(-5+2\right)^2+\left(1-7\right)^2}[/tex]

[tex]RS=\sqrt{\left(-3\right)^2+\left(-6\right)^2}[/tex]

on further simplification, we get

[tex]RS=\sqrt{9+36}[/tex]

[tex]RS=\sqrt{45}[/tex]

[tex]RS=3\sqrt{5}[/tex]

Similarly,

[tex]ST=\sqrt{\left(-7-\left(-5\right)\right)^2+\left(-5-1\right)^2}[/tex]

[tex]ST=2\sqrt{10}[/tex]

[tex]RT=\sqrt{\left(-7-\left(-2\right)\right)^2+\left(-5-7\right)^2}[/tex]

[tex]RT=13[/tex]

Now, the perimeter of the triangle RST is

[tex]Perimeter=RS+ST+RT[/tex]

[tex]Perimeter=3\sqrt{5}+2\sqrt{10}+13[/tex]

[tex]Perimeter=26.032759[/tex]

[tex]Perimeter\approx 26.0[/tex]

Therefore, the perimeter of the triangle RST is 26.0 units.

Answer:

x = 16.64

option A

Step-by-step explanation:

Using the pythagoreom therom

Answer:

16.64

Step-by-step explanation:

Since it's a right angled triangle, we use Pythagoras theorem:

(Hypotenuse)² = (base)² + (perpendicular)²

x² = 14² + 9²

x² = 196 + 81

x² = 277

√x² = √277

x = 16.64

Answer: D, -13<-10

Step-by-step explanation:

Which ever way the open part of the '<' is facing, means that it is greater than the other number.

-13 is smaller than -10 so the open part of the symbol would face towards -10 and the pointy part would fact towards the -13.

Answer: Yes, [tex]15\ m^2[/tex]

Step-by-step explanation:

Given

The surface area of the house [tex]A=500\ m^2[/tex]

Ayden aims to finish 80% of the painting

The actual painting done by him is [tex]A_c=415\ m^2[/tex]

Now 80% of the total is

[tex]\Rightarrow A'=500\times \dfrac{80}{100}=400\ m^2[/tex]

Clearly, actual painting done is more than 80% of the painting

[tex]\therefore[/tex] Ayden meet his goal

[tex]\Rightarrow A_c-A'=415-400=15\ m^2[/tex]

He painted [tex]15\ m^2[/tex] more than his target

Answer: 4:12 3:12

Step-by-step explanation:

Answer:

(n + 6)(n - 2)

Step-by-step explanation:

Given

n² + 4n - 12

Consider the factors of the constant term (- 12) which sum to give the coefficient of the n- term (+ 4)

The factors are + 6 and - 2 , since

6 × - 2 = - 12 and 6 - 2 = + 4

Then

n² + 4n - 12 = (n + 6)(n - 2) ← in factored form

Answer:

x=-4/3, y=3/-5

Step-by-step explanation:

X+2X=-4

Then, adding up we get: 3x=-4

Then, x=-4/3

Substituting those we get: 3*(-4/3)-5y=-1

-4-5y=-1

-5y=-1+4=3

y=3/-5

Thus, x=-4/3, y=3/-5

Answer:

14 installatons

42 service calls

Step-by-step explanation:

Let x = no. of new installations

      y = no. of service calls

(1)    x + y = 56           (2)    450x + 75y = 9450

            y = 56 - x               450x + 75(56 - x) = 9450

                                           450x + 4200 - 75x = 9450

                                            375x = 5250

                                                   x = 14 installatons

             y = 56 - 14 = 42 service calls

The number of installations are 14 and number of service calls are 42

Two or more expressions with an Equal sign is called as Equation.

Given,

An air-conditioning company counted 56 invoices at the end of the month.

For installation it charges  $450 and $75 for a service call.

Let x be number of installations

y be number of service calls

x+y=56...(1)

and 450x+75y=9450..(2)

From equation 1

x=56-y

Now substitute x value in equation 2

450(56-y)+75y=9450

Apply distributive property

25200-450y+75y=9450

25200-375y=9450

Subtract 25200 from both sides

-375y=9450-25200

-375y=-15750

Divide both sides by 375

y=42

Now put y value in equation 1

x+42=56

x=14

Hence, the number of installations are 14 and number of service calls are 42
