What is the value of y in the equation y − 7 = 21? (4 points)
Question 1 options:
1) 7
2) 17
3) 21
4) 28
Answer:
4
Step-by-step explanation:
y-7=21
+7 +7
y=21+7
y=28
Answer:
4) 28
Step-by-step explanation:
Isolate the y
add 7 to both sides
y - 7 = 21
y - 7 (+7) = 21 (+7)
y = 21 + 7
y = 28
28 is your answer

Which boxes have a volume of 120 cubic feet? Box A: length of 5 ft, width of 4 ft, height of 6 ft Box B: length of 7 ft, width of 7 ft, height of 6 ft Box C: length of 3 ft, width of 6 ft, height of 4 ft Box D: length of 10 ft, width of 3 ft, height of 4 ft
Answer:
Boxes A and D have a volume of 120 cubit feet.
Step-by-step explanation:
First, we just have to find the volume for each box so we do...
The volume of box A is:
(Length) x (Width) x (Height) = 5 ft x 4ft x 6ft = 120 [tex]ft^{3}[/tex]
The volume of box B is:
(Length) x (Width) x (Height) = 7ft x 7ft x 6ft = 294 [tex]ft^{3}[/tex]
The volume of box C is:
(Length) x (Width) x (Height) = 3ft x 6ft x 4ft = 72 [tex]ft^{3}[/tex]
The volume of box D is:
(Length) x (Width) x (Height) = 10ft x 3ft x 4ft = 120 [tex]ft^{3}[/tex]
Now we can see that boxes A and D have a volume of 120 cubit feet.

f(x)=−x 2 −4x−19 find f(-9)
Answer:
64
Step-by-step explanation:
The value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.
What is a function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given function is f(x) = x² −4x−19. The value of the function at f(-9) will be calculated as:-
f(x) = x² −4x−19
f(-9) = ( -9 )² - ( 4 x --9 ) - 19
f(-9) = 81 + 36 - 19
f(-9) = 98
Therefore, the value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.

Select the most appropriate response. An event A will occur with probability 0.4. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.20. We may conclude Question options: that events A and B are independent. that events A and B are dependent. that either A or B always occurs. that events A and B are mutually exclusive.
Answer:
Events A and B are dependent
Step-by-step explanation:
If A and B are two events such as A and B are dependent then
P(A∩B) [tex]\neq[/tex] P(A) P(B)
An event A will occur with probability 0.4 that is [tex]P(A)=0.4[/tex]
An event B will occur with probability 0.6 that is [tex]P(B)=0.6[/tex]
[tex]P(A)P(B)=0.4(0.6)=0.24[/tex]
The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20
Therefore,
P(A∩B) [tex]\neq[/tex] P(A) P(B)
So,
events A and B are dependent
According to the given probabilities, it is found that events A and B are dependent.
What are independent events?Two events, A and B are independent, if:
[tex]P(A \cap B) = P(A)P(B)[/tex]
In this problem, the probabilities given are:
[tex]P(A) = 0.4, P(B) = 0.6, P(A \cap B) = 0.2[/tex]
The multiplication is:
[tex]P(A)P(B) = 0.4(0.6) = 0.24[/tex]
Since [tex]P(A)P(B) \neq P(A \cap B)[/tex], the events A and B are dependent.

Which of the following is being constructed in the image?
A. a line parallel to a given line through a point, not on the line
B. a line perpendicular to a given line through a point not on the line
C. a line segment that is congruent to a given segment
D. a perpendicular bisector of a line segment
Alright, sorry for possibly wasting the answer, but its either D or B. i think its D, because its a bisector of the line segment, but B reads that it IS perpendicular, but on points not the line. You can rule out which one of the two it is, i would suggest asking a teacher for help or waiting for a better and more reliable answer.

Can someone PLEASE HELP!!
Answer:
the answer is 17.0 or just 17
Step-by-step explanation:
you have to use the pythagorean theorem, a^2 + b^2 = c^2
a = 11 and b = 13
11^2 + 13^2 = c^2
121 + 169 = c^2
290 = c^2
square root each side, so you have to find the square root of 290 which is 17.0293864
round it to the nearest tenth which is 17.0 but you can just write 17
hope this helps you understand it and answer it :)
Answer:
[tex]\boxed {\boxed {\sf c \approx 17.0}}[/tex]
Step-by-step explanation:
This is a right triangle because of the small square in the corner. Therefore, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs and c is the hypotenuse.
In this triangle, 11 and 13 are the legs because they make up the right angle. The missing side is the hypotenuse because it is opposite the right angle.
[tex]a=11\\b= 13[/tex]
[tex](11)^2+(13)^2=c^2[/tex]
Solve the exponents.
11²= 11*11=12113²= 13*13=169[tex]121+169=c^2[/tex]
Add.
[tex]289=c^2[/tex]
We are trying to solve for c, so we must isolate the variable. It is being squared. The inverse of a square is the square root, so take the square root of both sides.
[tex]\sqrt {289}= \sqrt {c^2}[/tex]
[tex]17.0293864=c[/tex]
Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 0 in the tenth place.
[tex]17.0 \approx c[/tex]
The missing side is approximately 17.0
