Solve 19×50 numerically

Answers

The solution of expression 19×50 is found as 950.

What is defined as the distributive property?

This property states that multiplying the product of two or more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.

The distributive property holds true for division the same way that it holds true for multiplication. However, with division, the concept of "breaking apart" or "distributing" can only be applied by dividing the numerator into lesser numbers that are exactly divisible even by divisor.

In other words, the distributive property requires a phrase of the form:

A (B + C) can be simplified as A (B + C) = AB + AC.

This same applies foe the subtraction;

Thus, for the given numerical;

= 19×50

Using distributive property.

= (20 - 1)×50

Open the braces;

= 20×50 - 1×50

= 1000 - 50

= 950

Therefore, the solution of the numerical 19×50 is 950.

Traffic signs are regulated by the Manual on Uniform Traffic Control Devices​ (MUTCD).

The perimeter of a rectangular traffic sign is 134 inches.​

Also, its length is 9 inches longer than its width.

Find the dimensions of this sign.

Answers

The dimensions of the rectangular traffic sign whose perimeter is 134 inches according to the task content are; 38in by 29in.

What are the dimensions of the rectangular traffic sign?

It then follows that from the task content that the dimensions of the rectangular traffic sign are to be determined.

Since the perimeter of a rectangle is given by;

P = 2(l+b)

where the length, l = b +9.

So therefore; 134 = 2(b+9 +b)

134 = 4b + 18

4b = 134 - 18

4b = 116

b = 29

In conclusion, the length, l of the traffic sign is; 29 +9

a possible equation for calculating the

Answers

The probability that a random bird chosen from among these is NOT a duck is 0.67

Given the total number of birds = 262

No of geese = 65

No of ducks = 84

No of robins = 113

We need to find the probability that a random bird chosen from among these is not a duck is

P ( not a duck ) = (total number of birds  - no of ducks) / total number of birds

                         =  262 - 84 / 262

                         =  178 / 262

Rita’s recipe for berry pies requires blueberries, raspberries, and strawberries. The ratio of cups of blueberries to cups of raspberries is 1 : 3. The ratio of cups of raspberries to cups of strawberries is 4 : 3. A batch of eight berry pies has a total of 25 cups of berries. How many cups of strawberries are in each pie?

Answers

Using proportions, it is found that there are 1.125 cups of strawberries in each pie.

What is a proportion?

A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.

For this problem, from the ratios, we have that:

The ratio of cups of blueberries to cups of raspberries is 1 : 3, hence, for each 4 cups, 1 is blueberry and 3 is raspberry.The ratio of cups of raspberries to cups of strawberries is 4 : 3, hence, for each 7 cups, 4 are raspberries and 3 are strawberries.

The least common multiple of 3 and 4 is 12, hence, multiplying 4 by 3, the ratio is:

Raspberries : Strawberries : Blueberries = 12 : 9 : 4

Meaning that our of 12 + 9 + 4 = 25 cups, we have that:

12 cups are of raspberries.9 cups are of strawberries.4 cups is of blueberries.

There amounts are for 8 pies, hence, for a single pie:

9/8 = 1.125 cups.

There are 1.125 cups of strawberries in each pie.

The angles in a triangle are in the ratio 1 : 2 : 3.

a) Show that the triangle is a right-angled triangle.

b) The hypotenuse of the triangle is 19 cm long.

Calculate the length of the shortest side in the triangle.

Answers

Answer:

  a) the largest angle is 90°, making it a right triangle

  b) the shortest side is 9.5 cm long

Step-by-step explanation:

You want the largest angle and the shortest side in a triangle whose angles are in the ratio 1 : 2 : 3.

Angles

Let x represent the smallest angle. Then the other two angles are 2x and 3x. Their sum is ...

  x +2x +3x = 180°

  x = 30° . . . . . divide by 6

  3x = 90° . . . . find the largest angle

The largest angle is 90°, a right angle. So, the triangle is a right-angled triangle.

Sides

A triangle with angles of 30°, 60°, and 90° is a "special" right triangle. Its sides are in the ratio 1 : √3 : 2. That is, the shortest side is 1/2 the length of the longest side.

  shortest side = 1/2(19 cm) = 9.5 cm

The length of the shortest side in the triangle is 9.5 cm.

__

Additional comment

In case you're not familiar with the side length ratios of the 30-60-90 special triangle, you can figure the side length from the Law of Sines. That tells you ...

  a/sin(A) = b/sin(B) = c/sin(C)

where A, B, C are the angles; and a, b, c are their opposite sides.

The shortest side is opposite the smallest angle, so we have ...

  a/sin(30°) = (19 cm)/sin(90°)

  a = sin(30°)×(19 cm) = 1/2(19 cm) = 9.5 cm

The length of the shortest side is 9.5 cm.

logs (20x + 5y) using the properties of logarithms to expand

Answers

The logarithmic expansion of logs(20x + 5y) by using the properties of logarithmic is log(5)+log(4x+y).

The basic logarithmic function is of the form f(x) = logₐx(r)n = logₐx, where a > 0. It is the inverse of the exponential function aⁿ = x. Log functions include natural logarithm (ln) or common logarithm (log). Logarithmic functions is very useful in various mathematical computations.

Given that, log(20x+5y) and we have to expand it by using the properties of logarithms. So, let's proceed to solve the question.

log(20x+5y)

we can write 20 in terms of powers like 20 = (2²)x5

log((2².5)x+5y)

log(5(2².5x/5+5y/5))

log(5(2²x+y))

log(5(4x+y))

log(ab) = log(a)+log(b)

⇒log(5(4x+y)) = log(5)+log(4x+y)

Hence, on expanding log(20x+5y) by using the properties of logarithms we get log(5)+log(4x+y) as our required answer.

What is a quadratic equation?

In algebra, a quadratic equation is any equation that can be rearranged in standard form as

ax² + b*x + c = 0

The figures a, b, and c are the portions of the equation and may be distinguished by calling them, independently, the quadratic measure, the direct measure, and the constant or free term.

The values of x that satisfy the equation are called results of the equation, and the roots or bottoms of the expression on its left-hand side.

A quadratic equation has at most two solutions.

Given,

Initial height h(0) = 3 ft

Initial upward velocity v(0) = 36 ft/sec

Given ball height after 't' seconds is h(t) = 3 + 36t - 16r²

for h= 19 ft

19 = 3 + 36 t - 16 r²

16 r² - 36 t + 16 = 0

4 r² - 9 t + 4 = 0

Quadratic equation for ax² + b*x + c = 0 is x = -b ±√b² - 4ac / 2a

By using the above formula we get

t = 9 ± √9² - 4*4*4 / 2*4

t = 9 ± √81 - 64 / 8

t = 9 ± √17 / 8

t = 9 + √17 / 8              t = 9 - √17 / 8

t = 9 + 0.5                    t = 9 - 0.5

t = 9.5                           t = 8.5

The values for which the ball's height is 19 feet are 9.5 sec and 8.5-sec using quadratic equations.
