i need the answer on the first one. (will give brainliest)

Answer:

[tex]b=\frac{4c-a^{2} }{3}[/tex]

Step-by-step explanation:

First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division

Then, you have [tex]4c=a^{2} +3b[/tex]

Subtract both sides by a squared

DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition

From that you get [tex]4c-a^{2} =3b[/tex]

Finally, divide both sides by 3.

You get  [tex]b=\frac{4c-a^{2} }{3}[/tex]

Answer:

m<K = [tex]146^{o}[/tex]

Step-by-step explanation:

With the given conditions in the question, it would be observed that ΔJKL is an isosceles, since KL ≅ JK. So that JL is the base of the triangle:

m<J ≅ m<L = [tex]17^{o}[/tex] (base angle of an isosceles triangle are equal)

Then;

m<J + m<K + m<L = [tex]180^{o}[/tex] (sum of angles in a triangle)

[tex]17^{o}[/tex] + m<K + [tex]17^{o}[/tex] = [tex]180^{o}[/tex]

m<K + 34 = [tex]180^{o}[/tex]

m<K  = [tex]180^{o}[/tex] - 34

m<K = [tex]146^{o}[/tex]

Thus, with respect to the given question, the measure of angle K is [tex]146^{o}[/tex]. Which is an obtuse angle of the triangle JKL.

Answer:

£11.25

Step-by-step explanation:

I = P * R * T

Where,

I = simple interest

P = principal = £100

R = interest rate = 2.25%

T = Time = 5 years

I = P * R * T

= 100 * 2.25% * 5

= 100 * 2.25/100 * 5

= (100 * 2.25 * 5) / 100

= 1,125/100

= 11.25

I = £11.25

5)alternate interior

Step-by-step explanation:

Answer:

h (x) = 5

h (x) = 2x + 1

h (x) = 2 x 2 + 1 = 5

x = 2

Answer:

x = 2

Step-by-step explanation:

Its given that h(x) = 2x + 1

But its also given that h(x) = 5

[tex]=> h(x) = 2x + 1 = 5[/tex]

[tex]=> 2x + 1 = 5[/tex]

Solve the equation.

[tex]=> 2x + 1 - 1 = 5 - 1[/tex]

[tex]=> 2x = 4[/tex]

[tex]=> \frac{2x}{2} = \frac{4}{2}[/tex]

[tex]=> x = 2[/tex]

Answer:

51 mph

Step-by-step explanation:

1734  miles

---------------- (per)

34 hours

you would divide. think of it as a fraction

1734

----

34

the numerator is miles and the denominator is hours. divide the numerator (the top number) by the denominator (the bottom number).

1734/34= 51

therefore, martino drove 51 miles per hour

Answer:

The free show shooters are likely to be successful after ten attempts

Step-by-step explanation:

Being successful 85% of the time means they have a probability of 85/100 = 0.85

This is for the free throw shooters

for the hitters, there is an average of 0.42

Looking at the two, 0.85 is a better probability compared to 0.42

This is because it is closer to 1

What this mean is that after 10 throws, it is possible that the free throw shooters are likely to be successful since they have the better probability

Answer:

The approximate probability that she checked a social website first and then a school-related website is 0.267.

Step-by-step explanation:

Given that a student wants to check six websites, and four of the websites are social and two are school-related, and after checking just two sites, she has to leave for school, to determine what is the approximate probability that she checked a social website first, then a school-related website, the following calculation should be performed:

4/6 x 2/5 = X

0.26666666 = X

Therefore, the approximate probability that she checked a social website first and then a school-related website is 0.267.

Answer:

Width = 13

Equation: 2 × 29 + 2W = 84

Step-by-step explanation:

Ace here!

I'm going to assume that we have to find the width. In a rectangle, there are 4 sides and opposite sides are congruent.

Let L represent the length and W represent the width.

Since there are 4 sides, we know that to find the of a rectangle perimeter, we have to do:

L+L+W+W=Perimeter

Let's first simplify this equation by combining like terms:

2L+2W = Perimeter

Now, let's plug in known values:

2(29) + 2W = 84

Divide everything by 2:

29+W=42

Isolate W:

W=42-29

W=13

Keep in mind, I didn't have to divide by 2 at the step that I had. I could've also done this:

2(29) + 2W = 84

Simplify:

58+2W=84

Bring everything to one side:

2W=26

Isolate W by dividing 2:

W=13

Two different slightly approaches, same answer.

I hope that helped, let me know if you have any questions.

Answer: SOLN,

let,<FHC be x

<GHC+<FHC( sum of  angle of triangle=180 degree

 x+6m+55+8m+55=180

 x+ 14m+110=180

  x+14m=180-110

  x+14m=70

    x=70 divied by 14m  

     x=5m

therefore,the value of <FHC is 5m.      

Answer:

Area of regular octagon is 102.16 ft².

Step-by-step explanation:

Using Formula

Area of regular octagon = 2 a ² ( 1 + √2 )

substitute the values

Area of regular octagon = 2 ( 4.6 ft ) ²( 1 + √2 )

Evaluate the exponent

Area of regular octagon = 2 × 21.16 ft ²( 1 + √2 )

Using distributive property

Area of regular octagon = 42.32 × 1 + 42.32 × √2

multiply, we get

Area of regular octagon = 42.32 + 59.84

Add

Area of regular octagon = aaprox. 102.16 ft ²

Therefore, area of regular octagon is 102.16 ft².
