The solutions to the inequality (k - 3)/4 > -2 are k = -1 and k = 0. This is determined by solving the inequality step by step and checking each given value.
To find the solutions, we need to solve the inequality step by step:
Start with the inequality: (k - 3)/4 > -2Multiply both sides by 4 to clear the denominator: k - 3 > -8Add 3 to both sides to isolate k: k > -5Now we find the values from the given options that satisfy k > -5:
k = -10: -10 > -5 (No)k = -7: -7 > -5 (No)k = -5: -5 > -5 (No)k = -1: -1 > -5 (Yes)k = 0: 0 > -5 (Yes)Thus, the values that are solutions to the inequality are k = -1 and k = 0.
The complete question is
Which values are solutions to (k - 3)/4 > - 2' Select two options.

Caleb started with 50 bacteria for his science experiment, and the number of bacteria doubled in one day. Jenna also started with 50 bacteria for her experiment, and after one day the number of bacteria was equal to 50 to the second power. How many bacteria did Caleb and Jenna each have in their experiments?
Answer:
100+50²=2600
Step-by-step explanation:
because 50x2=100 and 50² is 2500. Add those and you get 2600.
The number of bacteria Caleb and Jenna each have in their experiments is 2600.
Given that, Caleb started with 50 bacteria for his science experiment, and the number of bacteria doubled in one day.
What is the exponent?Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.
The number of bacteria doubled
= 2×25=50
The number of bacteria was equal to 50 to the second power
= 50²
= 2500
So total = 2500+100=2600
Therefore, the number of bacteria Caleb and Jenna each have in their experiments is 2600.

The standard deviation of sample data is "[tex]s = \sqrt{\frac{(x_1 -\bar{x})^2+ (x_2-\bar{x})^2 + ..... + (x_n -\bar{x})^2}{ n- 1}}[/tex]"
The standard deviation of the sample data:Random variables, samples, statistical populations, information sets, or probabilistic distributions are equal to the square root of its variance.
It's much less resilient in reality than the average absolute deviation, but it makes algebraic expressions easier.
A sampling divided by the size of the data set is less than one, n - 1. To get the standard deviation, take the square root of the variance. The standard deviation is obtained by taking the square root of the standard deviation.
Therefore, the standard deviation of sample data is "[tex]s = \sqrt{\frac{(x_1 -\bar{x})^2+ (x_2-\bar{x})^2 + ..... + (x_n -\bar{x})^2}{ n- 1}}[/tex]"

In the circle below, UW is a diameter and UX is tangent at U. Suppose m UV=128
Answer:
Step-by-step explanation:
The value of the angle ∠VUW is 26° and ∠VUX will be 116°.
What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circular objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
Given the circle
Since ∠UOV is 128°
So,
∠UOW = 180 - ∠UOV
∠UOW = 180 - 128 = 52°
Now,
∠VUW = 1/2 ∠UOW
∠VUW = (1/2)52 = 26°
Now ∠VUX = ∠VUW + 90°
∠VUX = 26 + 90 = 116°
Hence "The value of the angle ∠VUW is 26° and ∠VUX will be 116°".

Answer:
the sum of the first 10 terms is: 79.921875
Step-by-step explanation:
Notice that this is a geometric series, of the sequence that has "40" as the first term, and the following ones are obtained by multiplying by the common ratio "1/2".
So the common ratio [tex]r=\frac{1}{2}[/tex], and the first term [tex]a_1=40[/tex], then, recalling the formula for the partial sum of n terms of a geometric sequence:
[tex]S_n=\frac{a_1\,(1-r^n)}{1-r}[/tex]
we can find the sum of this sequence's first 10 terms (n=10):
[tex]S_n=\frac{a_1\,(1-r^n)}{1-r} \\S_{10}=\frac{40\,(1-(\frac{1}{2}) ^{10})}{1-\frac{1}{2} } \\S_{10}=79.921875[/tex]
Find the area of the isosceles triangle.

The area of the given isosceles triangle with 13 cm and 10 cm base will be 60 square cm.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
An isosceles triangle is a triangle in which two sides are the same.
The given isosceles triangle has been drawn below,
The area of a triangle is given as (1/2) × base × height.
Height = √(13² - 5²) = 12
Area = (1/2) × 10 × 12 = 60 square cm.

To find the area of an isosceles triangle with given side lengths, use the Pythagorean theorem to find the height. Then, apply the formula for the area of a triangle using the base and the calculated height. The area of the given isosceles triangle is 60 square centimeters.
To find the area of an isosceles triangle with a base of 10 cm and two equal sides of 13 cm, we first need to determine the height of the triangle. We can use the Pythagorean theorem to find the height (h).
Since the base splits the isosceles triangle into two right triangles, each having a base of 5 cm (half of 10 cm) and a hypotenuse of 13 cm:
Using the Pythagorean theorem:
→ Hypotenuse (hyp) = 13 cm
→ Base/2 (base) = 5 cm
→ Height (h) = ?
→ hyp² = base² + h²
→ 13² = 5² + h²
→ 169 = 25 + h²
→ h² = 169 - 25
→ h² = 144
→ h = √144
→ h = 12 cm
Now that we know the height, we can use the formula for the area of a triangle:
→ Area = 1/2 × base × height
→ Area = 1/2 × 10 cm × 12 cm
→ Area = 5 × 12
→ Area = 60 square centimeters

A triangle undergoes a sequence of transformations. First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units. How does the image triangle compare to the pre-image triangle?
The image triangle compare to the pre-image triangle will be similar due to dilation.
Step-by-step explanation:
As given in the question ,the sequence of transformation undergone by a triangle are :-
First, the triangle is dilated by a scale factor of 1/3 about the origin.Secondly, the triangle is reflected over the x-axis the triangle is translated left 3 units and up 2 units.
Due to the process of dilation, the two triangles will be similar. Another important factor is that the scale factor is less than one and is a reduction, thus, the image will be smaller than the pre-image but the triangle will be similar
The transformations mentioned in the above statement altered the position and scale of the triangle, but the angle measures of both the triangle remains the same.
Thus we can say that
The image triangle compare to the pre-image triangle will be similar due to dilation.
Answer:
Sample Response: Because there was a dilation, the two triangles will be similar. The scale factor was less than one, so the image will be smaller than the pre-image.

Simplify and solve for x. 5(x+20)= 7x+30
Answer:
x = 35
Step-by-step explanation:
Solve for x:
5 (x + 20) = 7 x + 30
Expand out terms of the left hand side:
5 x + 100 = 7 x + 30
Subtract 7 x from both sides:
(5 x - 7 x) + 100 = (7 x - 7 x) + 30
5 x - 7 x = -2 x:
-2 x + 100 = (7 x - 7 x) + 30
7 x - 7 x = 0:
100 - 2 x = 30
Subtract 100 from both sides:
(100 - 100) - 2 x = 30 - 100
100 - 100 = 0:
-2 x = 30 - 100
30 - 100 = -70:
-2 x = -70
Divide both sides of -2 x = -70 by -2:
(-2 x)/(-2) = (-70)/(-2)
(-2)/(-2) = 1:
x = (-70)/(-2)
The gcd of -70 and -2 is -2, so (-70)/(-2) = (-2×35)/(-2×1) = (-2)/(-2)×35 = 35:
Answer: x = 35
Answer:
x = 35
Step-by-step explanation:
5(x+20)= 7x+30
5x + 100 = 7x + 30
-30 -30
5x + 70 = 7x

Choose Yes or No to tell whether the expression represents a 20% discount off the price of an item that originally cost d dollars.
0.8d
d – 0.2
d – 0.2d
1 – 0.2d
The correct expression that represents a 20% discount off the original price d is 0.8d or d – 0.2d. The other options do not correctly represent a percentage discount from the original price.
Explanation:The expression that represents a 20% discount off the price of an item that originally cost d dollars would be calculated by first determining what 20% of the original price is, and then subtracting that value from the original price. So if the original price is d, then 20% of d is 0.2d. Subtracting that from d would give us the discounted price. Therefore, the correct expression that represents a 20% discount would be d – 0.2d, which simplifies to 0.8d.
d – 0.2 is not a percentage of d, but rather a fixed amount subtracted from d, and 1 – 0.2d is not meaningful in the context of pricing and discounts. So the expressions that represent a 20% discount off the price are:
Yes: 0.8dNo: d – 0.2Yes: d – 0.2dNo: 1 – 0.2dThe correct answers are the expressions: 0.8d and d – 0.2d.
