25/12 = 2.083333

or

35/6 turns to 70/12

70/12 x 25/12 = 1750/12  

1750/144 turns to 875/72

Answer:

Answer:

The temperature changed by 27F from midnight to noon.

Step-by-step explanation:

We can find the change in degrees by finding the difference of the two temperatures:

10 - (-17) = change in degrees

We can say the difference is equivalent to 10 + 17, since there are two negative signs (the subtraction sign and the negative sign)

So 10 + 17 = 27F difference.

Answer:

r, a, t, i, o

Step-by-step explanation:

Looking back at the question before this, Among these points, circle the points where x<y (the first coordinate, x, is smaller than the second coordinate, y.) the points were a, t, o, i, r. Those are the circled numbers.

Looking at this problem now, we will count those letters up from the y axis, in an increasing order. (also it spells out ratio)

Answer:

17x+15 is your answer, I think it is A communative

Step-by-step explanation:

The property is illustrated in step 3 would be A commutative properties of addition

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.

This property applies to multiplication also.

We are given the equation as;

5x + 1 + 12x + 4

= (5x + 1) + (12x + 4)

(5x + 12x) + (1 + 4)

Therefore, we can see that this shows the step of commutative properties of addition

Answer:

A. x = -3 ±√10

Step-by-step explanation:

ax² + bx = c

4x² + 24x = 4

The first step is to divide each term by 4 so you have a coefficient of 1 for x².

4(x² + 6x) = 4

Now, you want to divide the b term (6) by 2.

6/2 = 3

Square this quotient.

3² = 9

Because you have a 4 outside of the parentheses, before you add 9, you want to multiply it by 4.

9 • 4 = 36

4(x² + 6x + 9) = 4 + 36

Now, simplify the parentheses. You can use the factoring X, but a shortcut is to use the quotient you found from b/2.

4(x + 3)² = 40

Now, you can divide both sides by 4.

(x + 3)² = 10

Take the square root.

x + 3 = ±√10

Subtract.

x = -3 ±√10

This is your answer.

Answer: I don't know how to do the first question but I think I did the 2nd question correctly I believe we learned this in 7th grade.  I am a freshman so if it is wrong I am sorry anyways the answers for #2 are

and C: 30 for JL

Perimeter: is 79.  

This was fun to do lol ik it wasn't much but better than nothing.  

Step-by-step explanation:

Answer:

C:  66 in.

Step-by-step explanation:

The circumference formula is C = 2(pi)(r).  Here, r = 10.5 in.  Thus, the circumference of the clock to the nearest inch is:

2(3.14)(10.5 in) = 65.94 in, which rounds off to C:  66 in.

Answer:0.0009375 m2

Step-by-step explanation:

Answer:

Option A.

Length 16 feet

Width 12 feet

Step-by-step explanation:

2 cm=4 feet to scale

so you have this fraction:

2/4

or:

1/2

so for every cm, it's 2 feet.

6x2=12

8x2=16

so the width is 12 ft, the length is 16 ft. Option A

Answer: I believe it's A

Hope this helped love<3

Step-by-step explanation:

diameter = 20 inches

radius = diameter ÷ 2

radius = 20 ÷ 2

= 10 inches

circumference = 2π × radius

= 2 × 3.14 × 10

= 62.8 inches

Answer:

990 cm²

Step-by-step explanation:

Given ratio of radii = a : b , then

ratio of areas = a² : b²

Here

ratio of radii = 50 : 30 = 5 : 3 , then

ratio of areas = 5² : 3² = 25 : 9

let x be the area of sector DEF , then using proportion

[tex]\frac{25}{2750}[/tex] = [tex]\frac{9}{x}[/tex] ← [tex]\frac{ratio}{area}[/tex]

cross- multiply

25x = 24750 ( divide both sides by 25 )

x = 990

Area of sector DEF = 990 cm²

The perimeter of the given right triangle with hypotenuse 13 and base 5 is 30 units.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2  

We are given that;

hypotenuse=13, base=5

Now,

If the hypotenuse of a right triangle is 13 and one of the legs (also called the base) is 5, we can use the Pythagorean theorem to find the length of the other leg:

a^2 + b^2 = c^2

where a and b are the legs of the right triangle and c is the hypotenuse.

Substituting the given values, we get:

5^2 + b^2 = 13^2

Simplifying:

25 + b^2 = 169

b^2 = 144

b = 12

So, the length of the other leg is 12.

Now we can find the perimeter of the right triangle:

Perimeter = a + b + c

where a and b are the legs and c is the hypotenuse.

Substituting the given values, we get:

Perimeter = 5 + 12 + 13

Perimeter = 30

Therefore, by using pythagoras theorem the answer will be 30

Answer:

x = no. of quarters

3x = no. of dimes

3x + 11 = no. of nickels

2(3x + 11) = no. of pennies

340 quarters

1020 dimes

1031 nickels

2062 pennies

Step-by-step explanation:

x = no. of quarters

3x = no. of dimes

3x + 11 = no. of nickels

2(3x + 11) = no. of pennies

x + 3x + 3x + 11 + 2(3x + 11) = 4453

x + 3x + 3x + 11 + 6x + 22 = 4453

13x + 33 = 4453

13x = 4420

x = 340 quarters

3x = 1020 dimes

3x + 11 = 1031 nickels

2(3x + 11) = 2062 pennies

Check:  340 + 1020 + 1031 + 2062  = 4453
