HELP ME PLEASE ASAP?!?!
What is the area of the obtuse triangle given below?

Step-by-step explanation:

let the 2 numbers be x and y.

x - 8 = y --(1)

5x = 2y - 8 --(2)

sub (1) into (2):

5x = 2(x - 8) - 8

5x = 2x - 24

3x = -24

x = -8

sub x = -8 into (1):

y = -8 - 8 = -16

first number is -8 and second number is -16.

Answer:

-4

Step-by-step explanation:

I know this becasue I did it before but also becasue I checked my work with a slope calculator. You should use one if you don't want to hand do the work. If you do want to do the work it is y2-y1 over x2-x1 :)

Answer:

4900

Step-by-step explanation:

If 55% of workers are women, then 45% are not; therefore, we need to answer the following:

2205 is 45% of what number?

2205=45%x

2205/.45=x

4900=x

Divide total length needed by length of a piece:

230/8 = 28.75

Round up to 29

They need 29 pieces

Answer:

x= 14/9 = 1 5/9

Step-by-step explanation:

Use the distributive property to multiply 2 by 5x−3.

2(5x−3)−4=x+4

Subtract 4 from −6 to get −10.

10x−6−4=x+4

Subtract x from both sides

10x−10=x+4

Combine 10x and −x to get 9x.

10x−10−x=4

Add 10 to both sides.

9x−10=4

Divide both sides by 9.

x=  14/9

Answer:

x = -4

Step-by-step explanation:

x(x + 4) = 0

x = 0   ; x + 4 = 0

                 x = 0 - 4

                 x = -4

Answer:

Step-by-step explanation:

Step one:

given data

we are told that the cost of binoculars is $155.75

and also the sales tax is 6.5%

Step two:

We want to first solve for the sales tax which is 6.5% of  $155.75

=6.5/100* 155.75

=0.065*155.75

=10.12

Nick will pay a tax of $10.12

Also Nick will pay a total amount of

= 155.75+10.12

=$165.87

Answer: Time taken =1.25 x 10^1 hours 0r  4.5 x 10^4s

Step-by-step explanation:

Step 1

how long will it take the rocket to make the trip from Earth to the​ satellite = Time taken for the rocket to make the trip from Earth to the​ satellite

Speed = Distance / Time ,

Time = Distance / speed

Step 2-- solving

Time = Distance / speed

Time=2.5×10^5 miles/2.0×10^4 miles per hour

=12.5 hours  = 1.25 x 10^1 hours

or 1.25 x 10^1 hours  x 3600 = 45,000 seconds = 4.5 x 10^4s

Answer:

Step-by-step explanation:

Equation:

Total cost = $4 + $2(admission)

y = 4 + 2x

Initial value:

when x= 1 (one admission)

y= 4 +2(1) =6

so, $6

Answer:

  3x -4y = 12

Step-by-step explanation:

There are a number of different forms of the equation of a line. A few are ...

  y = mx + b . . . . slope-intercept form

  y -k = m(x -h) . . . . point-slope form

  x/a +y/b = 1 . . . . intercept form

  ax +by +c = 0 . . . . general form

  ax +by = c . . . . standard form

In "standard form", the coefficients a, b, c are mutually prime integers (have no common factors) and the leading coefficient (usually, 'a') is positive.

__

Given this graph, there are several ways to get to a standard form equation. Perhaps the quickest is to start with intercept form. We can see from the graph that the x-intercept is 4 and the y-intercept is -3. So, we can write the equation of the line in intercept form as ...

  x/4 +y/(-3) = 1

Multiplying this by 12 clears the fractions and gives us standard form:

  3x -4y = 12

Step-by-step explanation:

Answer:

v = 1 or -3

Step-by-step explanation:

2v^2 + 4v = 6

take 2 as common

2(v^2 + 2v = 3)

v^2 + 2v = 3

Now,

v^2 + 2v - 3 = 0

v^2 - v + 3v - 3 = 0

v(v - 1) + 3(v - 1) = 0

(v - 1) (v + 3) = 0

v = 1 or -3

Answer:

<=>v²+2v-3=0

<=>v²-v+3v-3=0

<=>v(v-1)+3(v-1)=0

<=>(v-1)(v+3)=0

<=>*v-1=0

v=1

*v+3=0

v=-3

Given :

A 18​-mile taxi ride takes 21 minutes and costs ​$12.60.

To Find :

The cost of a 39​- mile taxi ride. What unit price do you​ need.

Solution :

Unit price per mile :

[tex]p=\dfrac{12.60}{18}\\\\p = \$0.7\ /mile[/tex]

Cost of 39 mile taxi ride :

[tex]C = 39\times p\\\\C=39\times 0.7\\\\C=\$27.3[/tex]

Therefore, unit price is $27.3 and unit price is $0.7 / mile .

Hence, this is the required solution.

Answer:

1.1h+0.75c=4.55---------------1

h+c=5--------------2

Step-by-step explanation:

Step one:

given data

total lunch items= 5

let hot dogs be h

and cookies be c

cost of hot dogs = $1.10

cost of cookies = $0.75

total cost = $4.55

Step two:

The linear model for the total cost is given as

4.55=1.1h+0.75c---------------1

and the model for the number of items is

h+c=5--------------2

The systems of the equation for the situation is

1.1h+0.75c=4.55---------------1

h+c=5--------------2

Answer:

a. $22.2

b= 13.32/x=3/5

Step-by-step explanation:

13.32/x=3/5

13.32×5=66.6

66.6/3=22.2

x(present cost)=$22.2

Answer:

22.20$

3/5 * cost = 13.32

Step-by-step explanation:

3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)

to solve

5/3 to cancel out 3/5 and isolate the cost

5/3 * 13.32 = 22.20

Answer:

29.17 hours

Step-by-step explanation:

to find the zero of the function, set d to equal zero, so

0 = 70 - 2.4t

-70 = -2.4t

-70/-2.4 = t

29.17 = t
