Name the relationship between the angles below. What is the sum of the angles? Explain how you would find the missing angle. Explain each step. (replace with 120 & x)
Answers
Answer:
linear pair; supplementary anglessum is 180°subtract the known angle from 180°Step-by-step explanation:
Angles that form a straight line are called a linear pair. They are supplementary angles (by definition), so their sum is 180°.
__
Replacing the angle numbers with their values, we can use this relationship.
120 + x = 180 . . . . use the given numbers in the supplementary angle relationship
x = 180 -120 . . . . . use the addition property of equality to find x by subtracting 120 from both sides of the equation
x = 60
The missing angle (x) is 60 degrees.

how much degrees is angle y
Angle y is - degrees.
Answers
The whole equation has to equal 180 so always take the two or more number you have which in this case is 60 and 58 add them together to get 118 then subtract it by the common goal number which is 180 to get 62

Larry wants to purchase birthday gifts for his twin sisters. One sister likes daises which costs $2.00 per stem and the other likes tulips which costs $3.00 per stem. Which inequality could he use to determine how many of each flower he could buy if he only has $35.00 to spend? Let x represent the number of daisies and y the number of tulips. Group of answer choices
Answers
Answer: 2x + 3y = 35
Step-by-step explanation:
Let x = number of daisies
Let y = number of tulips
Since one sister likes daises which costs $2.00 per stem and the other likes tulips which costs $3.00 per stem, the inequality that could be use to determine how many of each flower he could buy if he only has $35.00 to spend will be:
2x + 3y = 35
In ∆DEF, ∠F = ∠D and EF = 4 cm and DF = 5 cm. Then find the length of DE
Answers
Answer:
DE = 4cm.
Step-by-step explanation:
The Isoscles Triangle Theorem says that:
"If two sides of a triangle are congruent, then angles opposite those sides are congruent."
The converse of this theorem is
"If angles opposite those sides are congruent, then two sides of a triangle are congruent."
Therefore, since ∠F is congruent to ∠D and are opposite sides ED and EF
while EF = 4 cm and DF = 5 cm.
DE = 4cm.

Answers
Answer:
x = -9
Step-by-step explanation:
2x + 8( x + 3 ) = 3( x - 13 )
Dstribute;
2x + 8 ( x + 3 ) = 3 ( x - 13 )
2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))
2x + 8x + 24 = 3x - 39
Combine like terms;
2x + 8x + 24 = 3x - 39
10x + 24 = 3x - 39
Inverse operations;
10x + 24 = 3x - 39
-3x -3x
7x + 24 = -39
-24 -24
7x = - 63
/7 /7
x = -9
2x+8x+24=3x-39
collect like terms, such as “2x+8x” this becomes 10x. plug in 10x.
10x+24=3x-39. now move variable and constant. 10x-3x=-39-24
collect like terms again. 10x-3x becomes 7x.
7x=-39-24.
-39-24=-63
7x=-63 divide both sides by 7.
x=-9

Company cuz closed at $52.93 per share with a P/E ratio of 15.17 how much were earnings per share
Answers
Answer: $3.49
Step-by-step explanation:
Earnings per share shows how much of the profit of the company every share will get.
You can use it to calcutae the P/E ratio through the following formula:
P/E ratio = Share price / Earnings per share
15.17 = 52.93 / EPS
EPS * 15.17 = 52.93
EPS = 52.93 / 15.17
= $3.49
What is the SCALE FACTOR (in decimal form) for a ratio of 6:15?
Answers
.....
......
......
Answer:
0.4
Step-by-step explanation:
You need to divide the 6 by 15 in order to get 0.4.
Ratios, fractions, decimals, and percentages are all pretty much each other, as ratios are just fractions but sideways with the colon in between the numbers. Ratios are to show a relationship, as well as the others. Fractions and ratios are decimals, as you can just simplify them into decimals. Percentages are just decimals but with the decimal moved over to the left twice. So 0.43 becomes 43%.
1.49 becomes 149%
0.00432 becomes 0.432%

Ivan will rent a car for the weekend. He can choose one of two plans. The first plan has no initial fee, but costs $0.90 per mile driven. The second plan has an initial fee of $75 and costs an additional $0.70 per mile driven. How many miles would Ivan need to drive for the two plans to cost the same?
Answers
Answer:
$337.50
Step-by-step explanation:
The computation of the number of miles need to drive for determining the same cost is given below:
Let us assume the miles be x
So for the first plan, the equation is
= $0.90x
And for the second plan, the equation is
= $75 + $0.70x
Now equate this
0.90x = $75 + 0.70x
0.90x - 0.70x = $75
0.20x = $75
x = $75 ÷ 0.20
= 375 miles
Now the same cost would be
For plan A and plan B
0.90x = $75 + 0.70x
0.90(375) = $75 + 0.70(375)
$337.5 = $75 + $262.50
$337.50 = $337.50

A stadium has 55,000 seats. Seats sell for $28 in Section A, $16 in Section B, and $12 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,156,400 from each sold-out event. How many seats does each section hold?
Answers
Answer: Section A holds 27500 , Section B has 14100 and SEction C has 13400.
Step-by-step explanation:
Let x= Number of seats in section A.
y = Number of seats in section B.
z= NUmber of seats in sectionC.
As per given , we have
x+y+z=55000 (i)
x= y+z (ii)
28x+16y+12z=1156400 (iii)
Substitute value of x from (ii) in (i), we get
[tex]x+x=55000\\\\\Rightarrow\ 2x=55000\\\\\Rightarrow\ x=27500[/tex]
From (i)
[tex]27500+y+z=55000\\\\\Rightarrow\ y+z=55000-27500\\\\\Rightarrow\ y+z=27500 \ \ \ (iv)[/tex]
From (iii), we get
[tex]28(27500)+16y+12z=1156400 \\\\\Rightarrow\ 770000+16y+12z=1156400\\\\\Rightarrow\ 16y+12z=386400\\\\\Rightarrow\ 4y+3z=96600 \ \ \ \ (v)[/tex]
Multiply 3 to (iv), we get
[tex]3y+3z=82500\ \ \ \ (vi)[/tex]
Eliminate (v) from (iv), we get
[tex]y=14100[/tex]
from (iv)
[tex]14100+z=27500\\\\\Rightarrow\ z=13400[/tex]
Hence, Section A holds 27500 , Section B has 14100 and SEction C has 13400.
