Choose the algebraic expression that represents the area of a triangle that has a base 8 inches less than 2 times wider than the height.
The algebraic expression for the area is:
A = (2H - 8)*H/2
How to write the algebraic expression?Here we want to write the expression:
"the area of a triangle that has a base 8 inches less than 2 times wider than the height."
Remember that for a triangle of base B and height H, the area is:
A = B*H/2
So if the base is 8 inches less than 2 times the height, we can write:
B = 2*H - 8
Replacing that in the area equation we get:
A = (2H - 8)*H/2
That is the equation for the area.

Here, A sphere is dilated by a scale factor of to create a new sphere.
So, The radius of old sphere = r
Then, The radius of new sphere = 5r
Hence, The volume of old sphere = 4/3 πr³
And, The volume of new sphere = 4/3 π × (5r)³

Calculate in the smartest way: (2^5 * 5^22 - 2 * 5 ^ 21) / 25^10.
The simplified value of the expression ((2⁵ x 5²² - 2 x 5²¹) / 25¹⁰ is 790.
To simplify the expression (2⁵ x 5²² - 2 x 5²¹) / 25¹⁰.
we can use the properties of exponents and the fact that 25 = 5².
First, let's simplify the numerator:
(2⁵ x 5²² - 2 x 5²¹)
Using the distributive property, we can factor out 5²¹ from both terms:
= 5²¹ x (2⁵ x 5 -2)
= 5²¹ (32 x 5- 2)
= 5²¹ (160-2)
= 5²¹ x 158
Now, let's simplify the denominator: 25¹⁰
Since 25 = 5², we can rewrite it as (5²)¹⁰, which gives us:
= (5²)¹⁰
= 5²⁰
Using the quotient rule of exponents \((a^m / a^n = a^{(m-n)})\), we can simplify further:
= 5²¹ x 158 / 5²⁰
= 5²¹⁻²⁰ x 158
= 5 x 158
= 790
Therefore, the simplified value of the expression ((2⁵ x 5²² - 2 x 5²¹) / 25¹⁰ is 790.

Hannah has a bag that contains pineapple chews, apple chews, and peach chews. She performs an experiment. Hannah randomly removes a chew from the bag, records the result, and returns the chew to the bag. Hannah performs the experiment 20 times. The results are shown below:
A pineapple chew was selected 5 times.
A apple chew was selected 7 times.
A peach chew was selected 8 times.
Based on these results, express the probability that the next chew Hannah removes from the bag will be a flavor other than peach as a percent to the nearest whole number.
The probability that the next chew Hannah removes from the bag will be a flavor other than peach is 60%.
What is Probability?The probability of an event is a number used in science to describe how probable it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the probability, the more probable it is that the event will take place.
According to question:The total number of chews that Hannah removed from the bag is 20.
Out of these 20 chews, a peach chew was selected 8 times, so the number of non-peach chews is 20 - 8 = 12.
Therefore, the probability that the next chew Hannah removes from the bag will be a flavor other than peach is 12/20 = 0.6.
To express this probability as a percentage, we multiply it by 100 and round it to the nearest whole number:
0.6 * 100 = 60
So the probability that the next chew Hannah removes from the bag will be a flavor other than peach is 60%.

an exponential function with growth factors of 1, then 2, then 4, ..
The best description of the graph is "a quadratic function with a constant difference of 2."
A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants. In a quadratic function, the graph forms a parabola.
In the given graph, if the differences between consecutive points on the graph are constant and equal to 2, it indicates a constant difference in the y-values (vertical direction) as the x-values (horizontal direction) increase. This is a characteristic of a quadratic function.
On the other hand, an exponential function with a growth factor of 2 would result in a graph that increases at an increasing rate, where the y-values grow exponentially as the x-values increase. This is not observed in the given graph.
Therefore, based on the information provided, the graph best represents a quadratic function with a constant difference of 2.

4x - 14y = - 42
4x + 7y=63
Answer:
(7,5)
Step-by-step explanation:
First, convert each equation into slope-intercept form to make it easy to graph.
4x - 14y = -42
14y = -4x + 42
y = (4/14)x + 3
This line has a slope of 4/14 and a y-intercept of 3.
4x + 7y = 63
7y = -4x + 63
y = -(4/7)x + 9
This line has a slope of -4/7 and a y-intercept of 9.
Finally, graph the two lines and find where they intersect (see the attached image).
