y - 7/8 = 3/4

what is y


;-;

Answers

Answer 1

Answer:

y = 13/8

Step-by-step explanation:

Here are the steps I did:

1. y - 7/8 = 3/4 x 2/2

2. y - 7/8 + 7/8 = 6/8 + 7/8

3. y = 13/8

Answer 2

Answer:

Y in (-oo:+oo) Y- (7/8) = 3/4 // - 3/4. Y- (7/8)- (3/4) = 0. Y-7/8-3/4 = 0. Y-13/8 = 0 // + 13/8. Y = 13/8. Y = 13/8.

1 AB

2 BC​

Answers

Answer:

AB ≈ 15.7 cm, BC ≈ 18.7 cm

Step-by-step explanation:

(1)

Using the Cosine rule in Δ ABD

AB² = 12.4² + 16.5² - (2 × 12.4 × 16.5 × cos64° )

       = 153.76 + 272.25 - (409.2 cos64° )

       = 426.01 - 179.38

       = 246.63 ( take the square root of both sides )

AB = [tex]\sqrt{246.63}[/tex] ≈ 15.7 cm ( to 1 dec. place )

(2)

Calculate ∠ BCD in Δ BCD

∠ BCD = 180° - (53 +  95)° ← angle sum in triangle

∠ BCD = 180° - 148° = 32°

Using the Sine rule in Δ BCD

[tex]\frac{BC}{sin53}[/tex] = [tex]\frac{BD}{sin32}[/tex] = [tex]\frac{12.4}{sin32}[/tex] ( cross- multiply )

BC × sin32° = 12.4 × sin53° ( divide both sides by sin32° )

BC = [tex]\frac{12.4sin53}{sin32}[/tex] ≈ 18.7 cm ( to 1 dec. place )

at least 6 sentences plz​

Answers

Answer:

We have a slope and a point, this way, we do not need to find the slope using two points. We can find the line using the Slope Form to turn it into Slope-Intercept Form, also known as "y = mx + b". We can use the Slope Form which is "y - y1 = m(x - x1)". A coordinate is "(x,y)", so that means, "(-1,4)" means that x = -1 and y = 4. We can substitute y1 for 4 and x1 for -1, and m for -5 since m is the slope. Plugging that information into the Slope Form Formula we get "y - 4 = -5(x - (-1))". We know that a negative with a negative turn positive, so we can use this information to change the formula to "y - 4 = -5(x + 1)". Now we distribute and simplify, these steps are shown below.

y - 4 = -5(x + 1)

y - 4 = -5x -5

y - 4 + 4 = -5x - 5 + 4

y = -5x - 1

Now that we have simplified it, we can see that the slope is -5 and the -1 is the y-intercept. To check this is a linear equation is to graph it, or substitute three x-coordinate or y-coordinates and draw a line. In conclusion, the equations is y = -5x - 1.

7(m+5) = 21

What is it?​

Answers

Answer:

m = -2

Step-by-step explanation:

Look at the attached image. First, we divide both sides by 7 to get m + 5 = 3. Now, we subtract 5 from both sides to get m = -2. Now, we substitute m for -2. As we can see, it checks out.

The solution of expression is,

m = - 2

We have to give that,

An expression to solve,

7 (m + 5) = 21

Now, simplify the expression as,

7 (m + 5) = 21

Divide both sides by 7,

m + 5 = 21 / 7

m + 5 = 3

Subtract 5 both side,

m = 3 - 5

m = - 2

So, The solution is, m = - 2

square root of 9 multiplied by square root of 180

Answers

Square root of 9 is 3 square root of 180 is 13.416roundes 3x13.416 is 40.248

Answer:

18√5

Step-by-step explanation:

√9×√180

from √9 we get 3 cause 3² is 9.

from 180 we get 6√5 because √36×5 is √180.

we took 36 out because it gives us a whole number if we square root it.

So √36×5 is 6√5 , because the square root of 36 is 6

then we multiply 3 and 6√5.

3×6 is 18 so we put 18 and put the √5 behind it.

Find the sum of the squares of 3, 2, 1, and -1

2 x 2=4

1x1=1

-1x-1=1

9+4+1+1=15

Answer:

15

Step-by-step explanation:

The square of 3 is 3 times 3, so 9.

2 times 2 is 4.

1 times 1 is 1.

-1 times -1 is 1, because the negative cancels out.

So, it's 9 plus 4 plus 1 plus 1, so the answer is 15.

A forest covers 68,000 acres. A survey finds that 0.8% of the forest is old-growth trees. How many acres of old-growth trees are there?

Answers

Answer:

544 acres

Step-by-step explanation:

There is 100% in a whole.

1% is 1/100th of the whole, or 0.01 of it. We get this because 1/100 = 1/100 = 0.01

Similarly, 0.8/100 = 0.008. We then multiply the decimal by the total to get

(0.008) ( 68000) = 544 acres

Can yall find EB? Round the the nearest hundred. AD=8.98, AB=6.47. ABCD is a rectangle

Answers

Answer:

5.53408980773 or 5.534

Step-by-step explanation:

Let's take AD as a, AB as b and DB as c

a2+b2 =c2

(8.98)2 + (6.47) 2 =c2

80.6404 + 41.8609 =c2

The number 2 is square . take it like square

122.5049 =c2

[tex] \sqrt{c \: \: } = \sqrt{122.5049 } [/tex]

C=11.0681796155

this valse is DB but the question say EB so dividend by 2 because rectangle diagonal are equal

So EB =11.0681796155/2

EB =5.5340890773
