Answer:
A) answer c ; B) X+3.7=15.3 ; C) 15.3 - 3.7 = 11.6 ---> 11.6+3.7=15.3
Step-by-step explanation:
Solution for A: First you have to look for the line underneath the bar says 15.3 as this will represent the total amount of liters in the bucket altogether. This would be bar c since we also know that we have 3.7 liters added but are missing the amount that was previously inside the bucket.
Solution for B: Let X resemble the unknown amount of water. To solve B, we need to write an equation. We know that there was already an amount of water in the bucket prior to us pouring more in so X is our first addend. We then added 3.7 liters of water to the unknown amount so that is our next addend giving you X+3.7=15.3
Solution for C: Now that we know our equation, we do the inverse operation (subtraction) in order to figure out the missing amount of water. This means we do
15.3 - 3.7 = 11.6

Kelly's little brother is exactly 3 feet tall. How tall is he in inches?
Answer:
he is 36 inches
Step-by-step explanation:
Answer:
36 inches
Step-by-step explanation:
We know that Kelly's little brother is exactly 3 feet tall, and we know how big he is in inches.
To solve first keep in mind that 1 feet is 12 inches.
Therefore if there are 3 feet, we would multiply the inches 3 times.
12 * 3
= 36
Therefore, Kelly's little brother is 36 inches.
A slide was installed at the local swimming pool, as shown here
What is the length of the slide?
Answer:
21.47 ft (rounded to the near hundreths)Step-by-step explanation:
Pythagorean Theorem : Right triangle with legs a and b and hypotenuse c
a=19 b = 10 c= x
19² + 10² = x²361 +100 = x²461 = x²x = square root of 461
x= 21.4709... (21.47 )
The required length of the slide installed at the local swimming pool is 21.47 ft.
A slide was installed at the local swimming pool, as shown here, what is the length of the slide is to be determined.
Perpendicular length = 10ft
base length = 19ft
In a right-angled triangle, its side of the right angle triangle, such as hypotenuse, perpendicular, and base are Pythagorean triplets.
Let the length of the slide at the local swimming pool is x,
applying Pythagorean theorem
hypotenuse² = perpendicular² + base²
x² = 19² + 10²
x² = 361 +100
x² = 461
x = √461
x = 21.47 ft
So, x = 21.47 is the length of the slide.
Thus, The required length of the slide installed at the local swimming pool is 21.47 ft.

Daniel loves pizza, so he decided to enter a pizza eating contest. Each contestant was given a 25inch pizza and the winner was determined by who ate the most! Daniel ate the entire pizza and won! How much pizza did he eat? (Hint 25 is the diameter?
Answer:
490.87 inches²
Step-by-step explanation:
Hi there!
What we're trying to find: the area of the circular-shaped pizza
What we know: the diameter of the pizza (25 inches)
Area of a circle = [tex]\pi r^2[/tex] where r is the radius of a circle
To find the radius, divide the diameter by 2:
25 inches ÷ 2 = 12.5 inches
Plug 12.5 inches into the area equation
[tex]A=\pi r^2\\A=\pi (12.5)^2\\A=\pi (12.5)^2\\A=156.25\pi \\A=156.25\pi \\A=490.87[/tex]
The area of the circle (pizza) is approximately 490.87 inches².
Therefore, Daniel ate 490.87 inches² worth of pizza.

100 POINTS FOR ANYONE WHO CAN ANSWER THESE! <3
Answer:
∠1 = 142°
reason: angles 1 and 2 are supplementary so they equal 180. 180-38 is 142
∠3 = 38°
reason: angles 2 and 3 are adjacent angles because they are diagonal from each other so they will equal the same measure.
∠4 = 142°
reason: since angle 4 is adjacent to angle 1 and is supplementary to angle 3, it has to be 142
∠5 = 38°
reason: since it is a transversal that means both of the intersections are the same measurements. so angle 5 is 38 since it matches up with angle 2
∠6 = 142°
reason: for the same reason as angle 5. angle 6 matches up with angle 1 so it has to equal 142.
∠8 = 142°
reason: since angle 8 is adjacent to angle 6 it has to equal 142. angle 8 is also a transverse angle to angle 4. and since angle 4 also equals 142, 8 has to also

Answer:
I hope this is right, im not sure because they are coincides or the same lines when overlapped, but I tried.
3x+0
Step-by-step explanation:
Using the formula mx+b we can get our answer.
We know that the two points pass through (7, 0)
mx+b is (slope)x+(y-intercept)
The slope of the two lines is 3 so we can replace m for 3:
3x+b
the y-intercept does not exist for these two lines as they are coincides, so we can just put it at 0, so we now have our equation 3x+0.

Give the starting value a, the growth factor b, and the growth rate r if Q = abt = a(1 + r)t.
Write r as a percent. Q = 0.0022(2.31) t
a. a = 0.0022
b = 2.31
r = 1.31%
b a = 0.0051
b = 231
r = 131%
c. a = 0.0051
b = 1.31
r = 1.31%
d. a = 0.0022
b = 2.31
r = 131%
Please select the best answer from the choices provided
Answer:
D. a = 0.0022
b = 2.31
r = 131%
Step-by-step explanation:
I calculated it logically
The starting value a, the growth factor b, and the growth rate r if Q = abt = a(1 + r)t. Write r as a percent. [tex]Q = 0.0022(2.31)^t[/tex] is Option a) a = 0.0022, b = 2.31, r = 131%
In the given formula, Q = abt = a(1 + r)t, the variables represent the following:
- "a" is the starting value.
- "b" is the growth factor.
- "r" is the growth rate expressed as a percentage.
Looking at the expression given: [tex]Q = 0.0022(2.31)^t[/tex], we can identify the values as follows:
- "a" = 0.0022
- "b" = 2.31
To find the value of "r," we need to rewrite the formula as Q = a(1 + r)^t and then solve for "r."
Given [tex]Q = 0.0022(2.31)^t[/tex], we can rewrite it as:
[tex]Q = a(1 + r)^t[/tex]
[tex]0.0022(2.31)^t = a(1 + r)^t[/tex]
Now, we can divide both sides of the equation by "a" to isolate the term
[tex](1 + r)^t[/tex]:
[tex](2.31)^t = 1 + r[/tex]
Next, subtract 1 from both sides to solve for "r":
[tex]r = (2.31)^t - 1[/tex]
Since the value of "t" is not specified, we cannot determine the exact numerical value of "r" without knowing the specific time "t." However, we can express "r" as a percentage, as requested.
So, the correct answer is: a) a = 0.0022, b = 2.31, r = 131%

determine the discount between the point(-4,2) and the line 4y=3×+6
Answer:
d = 14/5
Step-by-step explanation:
The point (-4,2) means that;
At x = -4, y = 2
Now general form of a linear equation is;
Ax + By + C = 0
We are given;
4y = 3x + 6
Rearranging to the form of a linear equation gives;
3x - 4y + 6 = 0
Thus, A = 3, B = -4 and C = 6
Thus, at point (-4,2), distance between them is;
d = (3(-4) - 4(2) + 6)/√(3² + (-4)²)
d = -14/5
We will take the absolute value.
Thus; d = 14/5

For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two-tailed, left-tailed, or right-tailed. The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months. A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
Choose the correct null and alternative hypotheses below.
A. H0: μ = 22.1 months
Ha: μ > 22.1 months
B. H0: μ = 22.1 months
Ha: μ 22.1 months
C. H0: μ = 22.1 months
Ha: μ < 22.1 months
D. H0: μ > 22.1 months
Ha: μ = 22.1 months
E. H0: μ 22.1 months
Ha: μ = 22.1 months
F. H0: μ = 22.1 months
Ha: μ > 22.1 months
Which of the following is the correct classification of the hypothesis test?
A. Two-tailed
B. Left-tailed
C. Right-tailed
Answer:
Option B:
[tex]H_0: \mu = 22.1[/tex]
[tex]H_a: \mu \neq 22.1[/tex]
Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:
[tex]H_0: \mu = 22.1[/tex]
A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:
[tex]H_a: \mu \neq 22.1[/tex]
Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
