Answer:
w = 5
Step-by-step explanation:
Combining like terms is a very important part to this equation!
5.2w - 1.4 = 3.2w + 8.6
I added 1.4 to the right side first, though you must do it to the left side of the equation as well
5.2w - 1.4 + (1.4) = 3.2w + 8.6 + (1.4)
5.2w = 3.2w + 10
Combine the remaining like terms. I subtracted 3.2w from both sides.
5.2w + (-3.2w) = 3.2w + (-3.2) +10
2w = 10
Now divide
2w = 10
w = [tex]\frac{10}2}[/tex]
w = 5

A. (–2, –1); maximum
B. (–2, –2); maximum
C. (–2, –1); minimum
D. (–2, –2); minimum
Answers
Answer:
D. (–2, –2); minimum
Step-by-step explanation:
It’s D you got to see the lowest part of the graph and you will call it mini except if the graph was going down you will call that point maximum.
Answer:
D. (-2, -2); minimum
Step-by-step explanation:
The vertex is the where the curve turns up/down which divides the figure into two halves.
From the given graph, the graph turns up at (-2, -2) , the graph moves down, therefore, the vertex (-2, -2); minimum.

Can someone pls help me find X and Y
Answers
Answer:
y = 35°
z = 90°
Step-by-step explanation:
the angle labeled as 35° and the angle labeled as 'y' are alternate-interior angles and are congruent
therefore, y = 35°
the third angle of the triangle on the left is 180-(90+35) = 55
therefore, this angle is vertical with the angle opposite it which is also 55°
to find 'z', you can add the two known angles of 55 and 35 and subtract the sum from 180 to get 90°

5y + 1 = 31 what’s the solution of y
Answers
Answer:
y = 6
Step-by-step explanation:
5y + 1 = 31
Subtract 1 from each side
5y + 1-1 = 31-1
5y = 30
Divide by 5
5y/5 = 30/5
y = 6
Answer:
y = 6
Step-by-step explanation:
5y means 5 multiplied by something. 5y + 1 equals 31. So 5 multiplied by 6 equals 30 + 1 = 31, which is the given answer.

Answers
Answer:

Step-by-step explanation:
From the question we are told that:
Angle [tex]\theta=28 \textdegree[/tex]
Height of Fence [tex]h=6 feet[/tex]
Generally the equation for Length of shadow cast by the fence is mathematically given by
Since
Shadow cast forms a right angle triangle
[tex]l_d=\frac{h}{tan \theta}[/tex]
[tex]l_d=\frac{6}{tan 28}[/tex]
[tex]l_d=\frac{6}{tan 28}[/tex]

(c) 5000 to 2 s.f
(d) 0.10000 to 2 s.f
0.10000 to 3 s.f
Step-by-step explanation:
Things to note when rounding off a number to a number of significant figures:
For a given number,
i. the most significant digit is the leftmost digit as long as it is not zero. For example, in 789, the most significant digit is 7.
ii. when rounding off to m significant figures, the least significant digit is the mth digit from the most significant digit. This can be zero. For example, to round off 789 to 2 significant figures, the least significant digit is 8 (since it's at position 2 starting from 7).
iii. every digit from the least significant digit is a non-significant digit. For example, to round off 789 to 2 significant digit, the digits after 8 (which is the least significant digit) are all non-significant. In this case, 9 is not significant. After rounding off, these non-significant digits are changed to zero.
iv. the first non-significant digit is the digit just after the least significant digit. For example, to round off 789 to 2 significant digit, the digit just after 8 (which is the least significant digit) is 9. Therefore, 9 is the first non-significant digit.
Rounding off rules
i. the least significant digit will be unchanged if the first non-significant digit is less than 5.
ii. the least significant digit will be increased by 1 if the first non-significant digit is greater than or equal to 5.
iii. all non-significant digits are either removed or changed to zero depending on whether the number is a decimal.
(a) 3748 (3 s.f)
The least significant digit here is 4 since it is at position 3 starting from the most significant digit 3
The first non-significant digit is 8 which is greater than 5.
Therefore, the least significant digit 4 is increased by 1 to get 5 and the non-significant digits (8 in this case) are changed to 0.
The result is thus 3750.
(b) 0.004070989 (4 s.f)
The least significant digit here is 0 since it is at position 4 starting from the most significant digit 4
The first non-significant digit is 9 which is greater than 5.
Therefore, the least significant digit 0 is increased by 1 to get 1 and the non-significant digits (8 and 9 in this case) are changed to 0.
The result is thus 0.004071000.
The ending zeros can be removed to give 0.004071
(c) 4971 (2 s.f)
The least significant digit here is 9 since it is at position 2 starting from the most significant digit 4.
The first non-significant digit is 7 which is greater than 5.
Therefore, the least significant digit 9 is increased by 1 to get 10. This is a sort of overflow. This means that the least significant digit will be 0 and a 1 will be added to the significant digit before it (5 in this case which will become 6 due to the addition). The non-significant digits (7 and 1 in this case) are changed to 0.
The result is thus 5000
(d) 0.09999 (2 s.f)
The least significant digit here is 9 since it is at position 2 starting from the most significant digit 9.
The first non-significant digit is 9 which is greater than 5.
Therefore, the least significant digit 9 is increased by 1 to get 10. This is a sort of overflow.
This means that the least significant digit will be 0 and a 1 will be added to the significant digit before it (9 in this case which will become 10 due to the addition).
This addition also causes an overflow thereby causing 1 to be added to the digit before it (0 in this case which will become 1 due to the addition). The non-significant digits (9 and 9 in this case) are changed to 0.
The result is thus 0.10000
The ending zeros can be removed to give 0.1
d (ii) 0.09999 (3 s.f)
The least significant digit here is 9 since it is at position 3 starting from the most significant digit 9.
The first non-significant digit is 9 which is greater than 5.
Therefore, the least significant digit 9 is increased by 1 to get 10. This is a sort of overflow.
This means that the least significant digit will be 0 and a 1 will be added to the significant digit before it (9 in this case which will become 10 due to the addition).
This addition also causes an overflow thereby causing 1 to be added to the digit before it (9 in this case which will become 10 due to the addition).
This addition also causes an overflow thereby causing 1 to be added to the digit before it (0 in this case which will become 1 due to the addition). The non-significant digits (9 in this case) are changed to 0.
The result is thus 0.10000
The ending zeros can be removed to give 0.1

Emma made 25 cookies. She gave cookies to her mom. Then, she split the remaining cookies evenly among 4 friends. Which expressions represent this scenario? Select all that apply. A (25+c)÷4 B 25÷4−c C 25−c4 D 25−4c E 25−c÷4 F (25−c)÷4 PLEASE HURRY
Answers
Answer: F. (25 − c) ÷ 4
Step-by-step explanation:
Emma had 25 cookies and gave c cookies to her mom and then divided the rest evenly amongst her 4 friends.
The cookies she shared to her friends are the 25 cookies minus the number of cookies she gave her mom which is:
= 25 - c
This (25 - c) was divided by 4 with each portion given to a friend so the total each friend got was:
= (25 - c) / 4

Answers
Answer:decrease by 12 feet
Step-by-step explanation:I did the math
A rectangular table has an area of 27 square feet. If its length and width are changed to 2/3 of their original size, the new area will be decreased by 12.
How does the area of a rectangle, and its length and width related?The area of a rectangle is the product of its length and width.
If a rectangle has a length L units and a width of W units, then
Area = L × W squared units.
A rectangular table has an area of 27 square feet. If its length and width are changed to 2/3 of their original size, what will be the effect on the area.
Area = L × W
Let the length and width are x and y
27 = x × y
xy = 27
The new area if its length and width are changed to 2/3 of their original size
Area = L × W
[tex]27 \times 2/3 \times 2/3\\\\= 3 \times 4\\\\= 12[/tex]
Therefore, the new area will be decreased by 12.
