Answer:

63 coins

Step-by-step explanation:

I am going to assume you are asking how many dollar coins are in the bag, I apologize if I am wrong.

So first, set up the problem. The total number is 517.6 and each coin weighs 8.1

So you would divide 517.6 by 8.1 to get 63.9012346 (which has too many decimal points so round)

But rounding up would get the wrong number because it would be too light for the amount of coins said to be in there, but rounding down gives you 63.

So 63 times 8.1 is 510.3 and the total could consider the weight of the bag into the total 517.6.

Answer:

[tex]7.5\ units^2[/tex]

Step-by-step explanation:

The formula to find the area of a trapezoid is the following,

[tex]A=(h)(\frac{(b_1)+(b_2)}{2})[/tex]

Where ([tex]h[/tex]) represents the heights of the trapezoid, ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.

One is given all of these values in the picture,

[tex]h = 2.5\\\\b_1 = 2\\\\b_2 = 4[/tex]

Substitute these values into the formula and solve for the area of the trapezoid,

[tex]A=(2.5)(\frac{(2)+(4)}{2})[/tex]

Simplify,

[tex]=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5[/tex]

Answer:

x = 33 degree

Step-by-step explanation:

angles of a triangle = 64 degree , 50 degree , 2x

64 + 50 + 2x = 180 degree (sum of interior angles of a triangle)

114 +  2x = 180

2x = 180 - 114

x = 66/2

x = 33 degree

to find 2x

=2*33

=66 degree

Answer:

250.50 - 35m = 300 - 45.25m

Step-by-step explanation:

Given :

International Business School :

Initial = 250.50

Spending per month = $35

Future Agricultural leaders club :

Initial = $300

Spending per month = 45.25

The number of months, m itvwi take for them to have the same amount of money :

Total spending after m months for both :

Initial - spending per month * number of months

International Business School :

250.50 - 35m - - - (1)

Future Agricultural Leaders Club :

300 - 45.25m - - - - - 2)

Equate both : (1) and (2)

250.50 - 35m = 300 - 45.25m

Answer:

250.50 - 35m = 300 - 45.25m

Rahal rewrites the expression as:

[tex][(-3)+(-7)]+(-6)[/tex]

To find:

The property that Rahal use to rewrite the expression.

Solution:

According to the associative property of addition, if a, b and c are three real numbers, then

[tex]a+(b+c)=(a+b)+c[/tex]

We have,

[tex]-3+[(-7)+(-6)][/tex]

Using the associative property of addition, we get

[tex]-3+[(-7)+(-6)]=[(-3)+(-7)]+(-6)[/tex]

Therefore, the required property is associative property of addition.

Answer:

  ∠SPR = 48°

Step-by-step explanation:

The relevant relations are ...

Since PR is a diameter, triangle PQR is a right triangle with angle PQR being the right angle.

This makes ∠PRQ complementary to ∠RPQ:

  ∠PRQ = 90° -28° = 62°

Exterior angle RTS is the sum of interior angles TRQ and TQR, so angle TQR can be found to be ...

  110° = 62° +∠TQR

  ∠TQR = 110° -62° = 48° = ∠SQR

__

Angle TQR, also angle SQR, subtends arc SR, so is the same measure as angle SPR, which also subtends the same arc.

  ∠SPR = 48°

Answer:

-2/3

Step-by-step explanation:

(9, 2)

(3, -2)

Slope form: y/x

Let's solve for x first: 9-3= 6

Now, insert x into the equation: y/6

Now for y: 2⇒-2= -4

Therefore -4/6, aka -2/3, is your answer.

Hope this helped! :)

Answer:

True

Step-by-step explanation:

same numbers on both sides = equivalent expression

1+2+4 = 7

7-5 = 2

So the first side is 2

-5 + 4 = -1

-1 + 2 + 1 = 2

So the second side is 2

Simplified, this is 2 = 2

This is TRUE because this is an equivalent expression,  demonstrated by the equal sign.

1-|-4|=5

Answer:

[tex]1-4=-3\\-1-4=-5\\-1+4=3\\1-(-4)=5[/tex]

Step-by-step explanation:

The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

Step-by-step explanation:

Given expressions 3x – 4 and 2x + 1 are equal. Then, 3x-4 = 2x + 1 3x- 2x = 1 + 4 [transposing 2x to LHS and -4 to RHS] x = 5

Hence, the value of x is 5.

Answer:

t = 4.7 days

Step-by-step explanation:

The half life formula is

N = No * e ^ (-kt)

Where No is the initial amount of the substance

N = 45 e ^ (-.1483 t)

We want 1/2 of the substance left

22.5 is half of 45 grams

22.5 = 45 e ^ (-.1483 t)

Divide each side by 45

1/2 = e ^ (-.1483 t)

Take the natural log of each side

ln(1/2) = ln (e ^ (-.1483 t))

ln(1/2) = -.1483t

Divide each side by -.1483

ln(1/2) / -.1483 = t

t=4.67395

Rounding to the nearest tenth

t = 4.7 days

Cross multiply.

x=69.899112...

x=69.899112...

{Add 3.5, the distance from the ground to her hand:}

Add 3.5, the distance from the ground to her hand:

69.899112...+3.5=

73.399112...

The kite is 73.4 feet above the ground.

A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.

Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.

Let h represent the perpendicular distance from the top of the kite to her hand. The angle of elevation = 34°. Hence:

sin(34) = h/125

h = 69.9 feet

The distance from the kite to the ground = 69.9 + 3.5 = 73.4 feet

Answer:

0.05 = 5/100

sqrt(0.05] = sqrt(5/100) = sqrt(5)/sqrt(100) = 2.24/10 = 0.224

0.0005 = 5/10000

sqrt [0.0005) = sqrt(5/10000) = sqrt(5)/sqrt(10000) =

= 2.24/100 = 0.0224

0.5 = 50/100

sqrt(0.5) = sqrt(50/100) = sqrt(50)/sqrt(100) = 7.07/10 =

= 0.707

0.005 = 50/10000
