Answer: The small side is 11, and the other two are 55, 55,
Step-by-step explanation:
So the perimeter adds up to 121 inches.
we know that two of the sides are 5x the 3rd side while being congruent.
11 times 5=55. 55 times 2=110. 110+11=121
Answer:
The third side is 11 inches
the 2 equal sides are 55 inches each side.
Step-by-step explanation:
X + 2(5x) = 121
x + 10x = 121
11x = 121
x = 121/11
x = 11

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

Melanie receives a 9% commission on every house she sells. If she received a commission of $20,340, what was the value of the house she sold?
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.
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
l = 38.

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?
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.

Solve 19×50 numerically
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.

[tex]\frac{5.025 \times 10^{10}}{1.5 \times 10^{8}} \\ \\ =\frac{5.025}{1.5}(100) \\ \\ =\boxed{335}[/tex]
Option A is correct, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.
To determine how many times larger one number is than another, we divide the larger number by the smaller number.
In this case, we want to find how many times larger 5.025 x 10¹⁰ is than 1.5 x 10⁸.
Dividing the larger number by the smaller number:
(5.025 x 10¹⁰) / (1.5 x 10⁸)
To simplify, we can divide the coefficients (5.025 / 1.5) and subtract the exponents (10¹⁰ - 10⁸):
(5.025 / 1.5) x 10¹⁰⁻⁸
Evaluating the division of the coefficients:
(3.35) x 10²
Therefore, 5.025 x 10¹⁰ is 3.35 x 10² times larger than 1.5 x 10⁸.
In decimal form, this can be expressed as:
3.35 × 10² = 335
Therefore, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.

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