what is each measure of the rhombus?

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

Step-by-step explanation:

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.

Hope this helps!

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:

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:

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

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

Step-by-step explanation:

Answer: 30

Step-by-step explanation:

Just did it

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

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

Step-by-step explanation:

diameter = 20 inches

radius = diameter ÷ 2

radius = 20 ÷ 2

= 10 inches

circumference = 2π × radius

= 62.8 inches

Answer:

Double - 7 5/6

Explantion: 2 1/4 times 2 equal 4 1/2 for the pancake mix

1 2/3 times 2 equal 3 1/3 for the milk

So.....4 1/2 plus 3 1/3 equals 7 5/6

Triple- 11 3/4

Explantion: 2 1/4 times 3 equals 6 3/4 for the pancake mix

1 2/3 times 3 for the milk equals 5

So.... 5 plus 6 3/4 equal 11 3/4
