Answer:

  x = 2, y = 10, sides = 15

Step-by-step explanation:

The hash marks tell you all of the sides are the same length. You can use this fact to relate the side length expressions to each other to solve for the variables.

We see that x appears in the left and right expressions only. So we can find x by setting those expressions equal to each other.

  8x -1 = 4x +7

  4x = 8 . . . . . . . . . . . . . add 1-4x to both sides of the equation

  x = 2 . . . . . . . . . . . . . . divide by 4; the value of x

  8x -1 = 8(2) -1 = 15 . . . the length of the sides

Now, we can find y using an expression that involves y. The top expression is the simplest:

  y +5 = 15 . . . . . the length of the side we just found

  y = 10 . . . . . . . subtract 5

The variable values are ...

  x = 2

  y = 10

The side lengths are 15.

Answer:

the number of deliveries would be 13

And, the equation is d ≥ 12.50

Step-by-step explanation:

The inequality function is given below:

Let us assume the d be the number of deliveries

10 × 8 + 6 × d ≥ 155

80 + 6d ≥ 155

6d ≥ 155 - 80

6d ≥ 75

d ≥ 75 ÷ 6

d ≥ 12.50

hence, the number of deliveries would be 13

And, the equation is d ≥ 12.50

Answer:

UW=[tex]2\sqrt{66}[/tex] (already solved for you)

UV=[tex]2\sqrt{33}[/tex]

m∠V=45°

Step-by-step explanation:

You're solving for sine because opp/hyp

sin(45°)*[tex]2\sqrt{66}[/tex]=UV

UV=[tex]2\sqrt{33}[/tex]

2) Now you need to solve for an inverse, and since you know UV, you can use inverse cosine (cos^-1) to find your answer

cos^-1([tex]\frac{11.4891}{2\sqrt{66}}[/tex])

m∠V=45°

Answer:

x = -2

Step-by-step explanation:

2 (x - 1) = 4x + 3

use the distributive property

2x - 2 = 4x + 3

    +2          +2

2x = 4x + 5

-4x  -4x      

-2x = 5

divide by -2

x = - 5/2

Answer:

B

Step-by-step explanation:

It seems more reasonable

Answer:

(a)Yellow=10

Green=38

Relative Frequency of Blue =0.32

Relative Frequency of Red =0.2

Relative Frequency of Green =0.38

(b)50 Red balls

Step-by-step explanation:

In 100 trials, the following were recorded.

Frequency of Blue Balls = 32

Frequency of Red Balls = 20

Relative Frequency of Yellow Balls =0.1

Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment

Total Number of Trials =100

Therefore:

Therefore, Number of Outcomes of Green balls=100-(32+20+10)

=100-62

Number of Outcomes of Green balls=38

(b)If the Number of Trials is Increased to 250

Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250

She should expect 50 red balls.

the diameter of a circle always passes the center, by knowing two diameters, you know the center is where they intersect

Step-by-step explanation:

yeah

----------------------------------

1)

Fact :: Reason

∠DCE = 90° :: sin ∠EDC = sin 30° = 1/2 = 8/16 = CE/DE

∠ACB = 90° :: ∠DCE and ∠ACB are vertical angles

∠ABC = 60° :: 180 - ∠CAB - ∠ACB = 60°

∠CED = 60° :: 180 - ∠EDC - ∠DCE = 60°

△CDE ⁓ △ABC :: Same angles (AAA)

2)

Let's solve for AB

sin 30° = 1/2

sin 30° = BC/AB = 15/AB

1/2 = 15/AB ⇒ AB = 30

AB = 30 in

Let's solve for AC (using another way)

AC/12 = 15/8

AC = 12 * 15 / 8   = 22.5

AC = 22.5 in

Step-by-step explanation:

if the conditional statement is “If Q then P

the answer is c=8

hope that helps lolol

Answer: c=8

Step-by-step explanation: All three angles in a triangle add up to 180 degrees so 9c+66+42=180. First add 66 and 42 which is 108, so now you have 9c+108=180. Then subtract 108 from both sides to get 9c=72. Finally, divide each side by 9 to isolate c and you get c=8

Answer:

Step-by-step explanation:

So 750 and 48.75

so tax is a percent of the whole or 750

750=100%

48.75=x%

750/100=48.75/x

solve for x

multiply both sides by x

750x/100=48.75

multiply both sides by 100

750x=4875

divide both sides by 750

x=6.5

the asnwe ris 6.5%

Answer:

4 miles=80 min?

Step-by-step explanation:

Question is confusin bruv

Answer:

15.7 percent of 80 = 12.56

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$80=100\%$

Step 4: Similarly, $x=15.7\%$.

Step 5: This results in a pair of simple equations:

$80=100\%(1)$.

$x=15.7\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{80}{x}=\frac{100\%}{15.7\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{80}=\frac{15.7}{100}$

$\Rightarrow x=12.56$

Therefore, $15.7\%$ of $80$ is $12.56$
