Answers
Answer:
26
Step-by-step explanation:
[(7+3)5-4]/2+3
-To solve this equation you have to use PEMDAS
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction-
- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])
Step 1) [(10)5-4]/2+3
- First you do "P," parentheses, so you add 7+3=10
Step 2) [50-4]/2+3
- Next you do "M," multiplication, and multiply 10x5=50
Step 3) [46]/2+3
- Then you do "S," subtraction, and subtract 50-4=46
(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)
Step 4) 23+3
- Now we do "D," division, and divide 46/2=23
Step 5) 23+3=6
- Finally we do "A," addition, and add 23+3=26 so the answer is 26
(FYI: "/" means division)

Step-by-step explanation:

f(-1) = |(-1)² - (-1) + 3| = |1 + 1 + 3| = |5| = 5
f(5) = |(5)² - (5) + 3| = |25 - 5 + 3| = |23| = 23
f(-10) = |(-10)² - (10) + 3| = |100 - 10 + 3| = |93| = 93

1/2 of 8 1/8=________
Answers
Answer:
One half of 8 1/8 is 4 1/16
Explanation:
Half of 8 is 4, and since the denominator of the fraction is 8, you'd have to double up to 16, since that's how fractions work.

Yuan makes punch by mixing cranberry juice and pineapple juice. For every 3 cups of pineapple juice, he uses 2 cups of cranberry juice. How much would make 10 cups? Please help me
Answers
call x is the amount of cup of pineapple, and y is the amount of cup of cranberry.
we have:
x + y = 10
x/y = 3/2 => x = (3/2)*y
x + y = 10
=> (3/2)y + y = 10
=> 3y + 2y = 20
=> 5y = 20
=> y = 4
x + y =10
=> x = 10 -4 = 6
=> 6 cups of pineapple and 4 cups of cranberry would make 10 cups

You put $500 in a savings account. The account earns $15.75 simple interest in 6 months. What is the annual interest rate?
Answers
Answer:
6.3%
Step-by-step explanation:
We're gonna use the simple interest formula: A = P(1 + rt)
A = Final amount (500 + 15.75 = 515.75)
P = Starting amount (500)
r = rate (?)
t = number of years (.5 since it's been half a year)
515.75 = 500(1 + 0.5r)
Disitribute the 500 to the equation inside the parenthesis
515.75 = 500 + 250r
Subtract 500 from both sides
515.75 = 500 + 250r
- 500 - 500
15.75 = 250r
Divide both sides by 250
15.75/250 = 250r/250
r = 0.063

29. Find the missing coordinate that would result in the given slope. (x, 2) and (5, -4) if m= -3
Answers
Answer:
Set up an equation (you can use the distance formula as an equation). The distance formula is Y2-Y1/X2-X1.
2-(-4)/x-5=-3
6/x-5=-3
Multiply both sides by x-5.
6=-3(x-5)
Distribute the -3 to the terms in the parentheses.
6=-3x+15
Subtract 15.
-9=-3x
Divide both sides by -3.
3=x
So, the missing number of the coordinate is 3.

If angle 5 measures 110 degrees , what is the measure of angle 2?
A) 55 degree
B) 70 degree
C) 110 degree
D) 160 degree
Answers
Answer:
the vertex is 70 degrees and the other 2angles are 55 degrees each
in a triangle the angles must total to 180 degrees.
if the exterior angle is 110 degrees the supplementary angle of this angle would be = 180-110= 70 degrees
as it is an isosceles triangle the other two angles must be equal.
such that x+x+70= 180 , where x are the angles of the base
2x= 180-70
2x=110
x=110/2
x= 55

Brianna planted daffodils and tulips in her garden. She planted 4 daffodils for every 3 tulips. if Brianna planted 28 flowers in all, how many tulips did she plant?
Answers
Answer:
12
Step-by-step explanation:
4+3=7
7x4=28
3x4=12
Answer:
Step-by-step explanation:
The ratio is 4 daffodils to 3 tulips.
Let the daffodils = d
Let the Tulips = t
d/t = 4/3 Cross Multiply
3d = 4t Divide by 3
3d/3 = 4t/3 Combine
d = 4/3 * t
d + t = 28
4/3 t + t = 28 Change 1t to 3/3 t
4/3 t + 3/3t = 28 Add the fractions.
7/3 t = 28 Multiply both sides by 3/7
3/7 * 7/3t = 28 * 3/7
t = 4 * 3
t = 12
12 tulips were planted. This is the algebraic method of doing the question. If you are in an algebra class, the question really should be done this way.

The degree of f(x) is at least 7
O The degree of f(x) is at least 6.
The degree of f(x) is at most 8.
The degree cf) is at most 7
Answers
Step-by-step explanation:
the degree of f(x) is at least 8.
a squared function has 1 turning point.
a cubic function has 2 turning points.
and so on.
under certain circumstances some turning points or also zero points can merge into the same point.
formally they all count separately, but practically they are the same.
so, when we can SEE 7 turning points, there must be at least a degree of 8 or more.
a function with lower degree can never "create" additional turning points.
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 8 people took the trip. She was able to purchase coach tickets for $360 and first class tickets for $970. She used her total budget for airfare for the trip, which was $5320. How many first class tickets did she buy? How many coach tickets did she buy?
Answers
Answer:
$3990
Step-by-step explanation:
So first,you need to add the dollars that Sarah spend and which is equal to $1330($360+$970) and you need to subtract the money that Sarah spend($1330) and the budget of her money ($5320) so which is $5,320-$1,330 so the answer is $3,990

What is an equation of the line that passes through the points (3,-6) and
(-7, - 6)?
Answers
Answer:
If you want to show no work, the answer is y = -6
If you are required to show work:
The slope between the two points is(-6 - -6) / (-7 - 3) = 0/-10 = 0 and the y intercept has to be -6 so according to the slope intercept form of a line the equation would be y = 0x + (-6) or just y = -6
The admission fee at an amusement park is $1.50 for children and $4.00 for adults. On a certain day, 2,900 people entered the park, and the
admission fees that were collected totaled $6,100. How many children and how many adults were admitted?
Answers
Step-by-step explanation:
x= children
y= adult
First equation: x+y= 2900
Second equation: 1.50x + 4y= 6100
From first equation: x+y= 2900
x= 2900-y, becomes the third equation
Second equation: 1.50(2900-y) + 4y= 6100
4350-1.50y+ 4y= 6100
2.5y = 1750
y= 700
700 adults
Thrid equation: x= 2900-700
= 2200
2200 children
So total have 700 adults and 2200 children

The coordinates of the three vertices of a triangle are
(-2,5), (4,0), and (-2, 0). What is the area of the triangle?
Answers
Answer:
15
Step-by-step explanation:
Find side lengths.
(-2, 0) and (4, 0) are 6 apart.
(-2, 0) and (-2, 5) are 5 apart.
Triangle area is 1/2 of a rectangle [for this case].
6*5 = 30
30/2 = 15
Answer:
15 unit^2.
Step-by-step explanation:
The line between the points (4,0) an (-2, 0) is horizontal ( as the y coordinates are the same) and is of length
4- (-2) = 6 units.
The line between (-2,5) and (-2,0) is vertical and of length 5 - 0 = 5 units.
So it is a right triangle and the area is 1/2 * 5 * 6
= 15 unit^2.
