Answer:

3.75 quarts, rounded to 3.8 quarts

Step-by-step explanation:

3 quarts of solution is 10% antifreeze, so 0.3 quarts are already antifreeze, and 2.7 quarts are not.

a(the antifreeze we already have)+x(what we're going to add)= 1.5*2.7

Let me explain. If we have 60% antifreeze, 40% is not. 60/40=1.5

Substitute a for 0.3

0.3+x=4.05  Subtract 0.3 from both sides

x=3.75

Answer:

I think the volume is 15

Step-by-step explanation:

2.5 x 3 then multiply that by 2

Answer:

The answer is d and b hope this helps!

Step-by-step explanation:

Let the number be x

10% of x = 15

10/100 × x= 15

⅒ × x = 15

x= 15×10

x=150

Answer: ∠DOB: 48°

Step-by-step explanation:

1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°

2. now we can solve for the missing variable, n.

108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°

3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°

Answer:

8 1/4 ft

Step-by-step explanation:

Answer:

The two possible measures tobproduce a ️ are ''Three angles: 62, 32°, and 84°" & "Three sides: 4cm, 7cm, and 9cm"

The triangle is formed by two sides of 4 cm and 7 cm with an angle of 54° between those two sides

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

Two sides of 4 cm and 7 cm with an angle of 54° between those two sides would produce two possible triangles.

This is because if the angle is between the two sides, the two sides can be positioned in two different ways to form two distinct triangles, whereas if the angle is not between the two sides, only one triangle can be formed.

The other measures listed do not provide enough information to determine if there are one or two possible triangles.

Hence , the triangle is solved

Answer:

She biked 8 blocks

Step-by-step explanation:

Answer:

0.6796875

Step-by-step explanation:

1. We assume, that the number 9.375 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 9.375 is 100%, so we can write it down as 9.375=100%.

4. We know, that x is 7.25% of the output value, so we can write it down as x=7.25%.

5. Now we have two simple equations:

1) 9.375=100%

2) x=7.25%

where the sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

9.375/x=100%/7.25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 7.25% of 9.375

9.375/x=100/7.25

(9.375/x)*x=(100/7.25)*x       - we multiply both sides of the equation by x

9.375=13.793103448276*x       - we divide both sides of the equation by (13.793103448276) to get x

9.375/13.793103448276=x

0.6796875=x

x=0.6796875

now we have:

7.25% of 9.375=0.6796875

The percentage of the mile 7.25% of 9.375 =0.6796875.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have to find percentage of the mile times range from 7.25 to 9.375.

let 9.375 represents 100% and x represents 7.25%.

Then, using proportion we can write

9.375/x=100%/7.25%

9.375/x=100/7.25

9.375 (7.25)= 100x

100x = 67.96875

x= 0.6796875

Thus, 7.25% of 9.375 =0.6796875

Answer:

$30.135 or if rounded up $30.14

Step-by-step explanation:

subtract 35 from 396.62

396.62 - 35 = 361.62

divide 361.62 by 12

361.62/12 = 30.135

Answer:

e

Step-by-step explanation:

Jayden bought an item for $396.62 with sale tax.

He already payed $35 as a down payment.

396.62 - 35 = 361.62

He pays the item in 12 equal monthly payments.

361.62 / 12 ≈ 30.14

(really equal to 30.135)

he pays abt $30.14 each month

Answer:

0

Step-by-step explanation:

So,0= the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.

Hence, the values for different conditions were calculated with the help of trigonometric functions.

Part A

θ=kπ

Where k is an integer k=0,1,2..

Part B

θ=[tex]k\frac{\pi }{2}[/tex]

Where k is an integer k=0,1,2..

Part C

θ=kπ

Where k is an integer k=0,1,2..

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths

Part A

Given that,

f(x)=2sinθ+[tex]\sqrt{2}[/tex]

Non compressed length = [tex]\sqrt{2}[/tex]

Then

2sinθ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]

2sinθ=0

sinθ=0

Therefore θ is the integer multiple of π

θ=kπ

Where k is an integer k=0,1,2..

Part B

Here angle is doubled

Then,

2sin2θ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]

2sin2θ=0

sin2θ=0

Here θ will be the integer multiple of [tex]\frac{\pi }{2}[/tex]

θ=[tex]k\frac{\pi }{2}[/tex]

Where k is an integer k=0,1,2..

Part C

g(x)=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]

Here

f(x)=g(x)

2sinθ+[tex]\sqrt{2}[/tex]=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]

2sinθ=1-[tex]cos^{2}[/tex]θ

we know that [tex]1-cos^{2}[/tex]θ=[tex]sin^{2}[/tex]θ

2sinθ=[tex]sin^{2}[/tex]θ

sinθ=0

Therefore θ is the integer multiple of π

θ=kπ

Where k is an integer k=0,1,2..

Hence, we have solved that

Part A

θ=kπ

Where k is an integer k=0,1,2..

Part B

θ=[tex]k\frac{\pi }{2}[/tex]

Where k is an integer k=0,1,2..

Part C

θ=kπ

Where k is an integer k=0,1,2..

How to solve:

    Let's follow his process step-by-step to analyze what property is being used. The breakdown is as follows:

Jayden's work

Set up equation                                                     9(2 + 7x)

Step 1                                                                      9(7x + 2)

Step 2                                                                     9(7x) + 9(2)

Step 3                                                                      (9*7)x + 18

Breakdown

Set up equation                                                     9(2 + 7x)

Step 1: Commutative Property of Addition

This property states that when adding, the order of the numbers being added does not matter, and are therefore interchangeable.

Original equation: 9(2 + 7x)

Equation's formula: a(b + c)

Changed equation: 9(7x + 2)

Equation's formula: a(c + b)

By swapping the b and c values in the parentheses, Jayden is demonstrating the Commutative Property. Both will still produce the same sum.

Step 2: Distributive Property of Multiplication

This property states that the sum of two addends that are multiplied by the same number is equal to the product of that number multiplying the sum of both addends.

Original equation: 9(7x + 2)

Equation's formula: a(c + b)

Changed equation: 9(7x) + 9(2)

Equation's formula: a(c) + a(b)

By splitting the parentheses and multiplying each term separately, Jayden is demonstrating the Distributive Property. Both will produce the same product.

Step 3: Associative Property of Multiplication

This property states that the product of three terms, where one is outside of the parentheses multiplying the other two, is not affected by changing which term is on the outside of the parentheses.

Original equation: 9(7 * x) +18

Equation's formula: a(c*x) + (ab)

Changed equation: x(7*9) + 18

Equation's forumula: x(c*a) +18

By swapping the 9 and x variables, Jayden is demonstrating the Associative Property. Both will produce the same product.

Simplified:

Step 1 - Commutative Property

Step 2 - Distributive Property

Step 3 - Associative Property

Perimeter = 12

Area = 8

Step-by-step explanation: For the perimeter add all the sides so the top and bottom is both 2 so 2+2 = 4.

For the sides its both 4 so 4 + 4 = 8.

8 + 4 = 12

So the perimeter is 12.

For area just count all the blue squares and there is 8 squares.

So the area is 8.
