Answer:

8 1/8 gallons

Step-by-step explanation:

2 1/2 = 5/2

3 1/4 = 13/4

(5/2)(13/4) = 65/8 = 8 1/8 gallons

Answer: 10

Step-by-step explanation:

Question A:

The formula to find the hypotenuse is c²=a²+b²

So you would insert the numbers into the formula which would be c²=8²+6²

8²=64

6²=36

36+64=100

So c²=100

Then you want to find c on its own so you have to square root 100.

The square root of 100 is 10.

You have to use this method for the rest of the triangles.

The hypotenuse of the triangles are solved

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

a)

a = 8

b = 6

Now , From the Pythagoras Theorem , The hypotenuse² = base² + height²

c = √ ( 8 )² + ( 6 )²

c = √100 ≈ 10

b)

a = 11

b = 7

c = √170 ≈ 13.0

c)

a = 13

b = 6

c = √205 ≈ 14.3

Hence , the hypotenuse of the triangles are solved

Answer:

Well to start you already know the sandwich cost 5.25 and the total sales tax .92.

To find the cost of each drink

5.25 x 2= 10.50

10.50+.92=11.42

17.00-11.42= 5.58

5.58/3= 1.86

So the cost per Drink is $1.86

Answer:

for the third question y = 5, x = 3

Step-by-step explanation:

Answer:

y=1

Step-by-step explanation:

Let's solve your equation step by step.

Step 1: Simplify both sides of the equation.

−4(2y−4)−4y=4

(−4)(2y)+(−4)(−4)+−4y=4(Distribute)

−8y+16+−4y=4

(−8y+−4y)+(16)=4(Combine Like Terms)

−12y+16=4

−12y+16=4

Step 2: Subtract 16 from both sides.

−12y+16−16=4−16

−12y=−12

Step 3: Divide both sides by -12.

y=1

Answer:

2< AC<8

Step-by-step explanation:

For a triangle to exits sum of two sides must always be greater than the the third side

⇒ AC<  AB+ BC =5+3=8 in

⇒AC<8 in

Also, the  difference of the two sides must be smaller than the length of third side

⇒ AC> | AB-BC| = |5-3| =2

AC> 2 in

therefore,  we can say  2< AC<8. Hence, AC can takes 3,4,5,6 values

Step-by-step explanation:

f(4) is just asking what the y value is when x=4 which is 1

f(-3) = -4

This has no minimum or maximum because the range is all real numbers (the y value goes to infintiy and negative infinity)

f(3)=6

f(0)= 3

This has a minimum because the lowest y value possible is not infinity (it's 2)

f(1)= -5

f(4)= -2

max= -1

f(-1)= 0

f(6)= -5

Answer:

Width: 4 meters. Length: 11 meters

Step-by-step explanation:

If you do it correctly, the length should be 3 more greater than 4*2. 4*2= 8 +3= 11. Your perimeter= 30 meters. 11+11 accounting for both long sides of the rectangle= 22. Accounting for both sides of the width, so 4*2=8 + our 22= 30 meters. Yw.

The length of the rectangle​ width 4 meters and length 11 meters.

If you do it correctly,

The length should be 3 more greater than

P=2(l+w)

L= Length

W = Width

4*2. 4*2= 8 +3= 11.

Your perimeter= 30 meters.

11+11 accounting for both long sides of the rectangle= 22.

Accounting for both sides of the width,

So 4*2=8 + our 22= 30 meters.

Therefore we get the length of a rectangle is  11 meters.

n = 64

Step-by-step explanation:

3/4n - 8 = 5/8n

-8 = 5/8n - 6/8n

-8 = -1/8n

-n = -64

n = 64

The unknown number is 64.

Important information:

[tex]\dfrac{3}{4}[/tex] of a number [tex](n)[/tex] is [tex]\dfrac{3}{4}n[/tex].

Difference between [tex]\dfrac{3}{4}[/tex] of a number [tex](n)[/tex] and 8 is [tex]\dfrac{3}{4}n-8[/tex].

[tex]\dfrac{5}{8}[/tex] of the number is [tex]\dfrac{5}{8}n[/tex].

Using the given information form a linear equation.

[tex]\dfrac{3}{4}n-8=\dfrac{5}{8}n[/tex]

Now, solve the equation.

[tex]\dfrac{3}{4}n-\dfrac{5}{8}n=8[/tex]

[tex]\dfrac{6n-5n}{8}=8[/tex]

[tex]\dfrac{n}{8}=8[/tex]

Multiply both sides by 8.
