A banana split costs $2.50. A milkshake costs $1.70. Bobby,Jack, and Ted ordered one of each and split the cost. How much does each boy owe?
Answer:
$4.20
2.50+1.70=4.20
Answer:
Jack= $4.20
Bobby=$4.20
Ted=$4.20
Step-by-step explanation: This is the answer because if you add up all the drinks the total they payed is $12.60 so you just divided that by how many people there are and get $4.20

Answer:
72.5°
Step-by-step explanation:
180° is a straight line. Subtract 35° from 180°, you get 145°, now divide 145° by 2, you will get 72.5°.
Hope this helped.
The sum of all angles is 360
we have one angle given which is 35 degrees the angle infront of it is also the same as opposite angles are always equal
so x= 35
for y as said earlier opposite angels are equal so the empty 2 angles are also y
so now we have
[tex]4y+35+35=360\\4y+70=360\\4y=290\\y= 72.5[/tex]
so y=72.5 degrees

A city is interested in building a parking garage in a certain area. Three hundred randomly selected residents from this area were asked, "Do you support the city's decision to build a parking garage in your area?" Of the 300 residents interviewed, 203 said no, 7 said yes, and 90 had no opinion. A large-sample z-confidence interval, p ± z * square root of p hat times 1 minus p hat over n, was constructed from these data to estimate the proportion of the residents who support building a parking garage in a certain area. Which of the following statements is correct for this confidence interval?
This confidence interval is valid because a sample size of more than 30 was used.
This confidence interval is not valid because the quantity np is too small.
This confidence interval is valid because each area resident was asked the same question.
The confidence interval is valid because no conditions are required for constructing a large-sample confidence interval for a proportion.
This confidence interval is not valid because "no opinion" was included as a response category for the question.
Answer:
This confidence interval is not valid because the quantity np is too small.

The measure of the length and width of the rectangle is given as 135 feet and 92 feet respectively.
What is a rectangle?A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
Here, we have,
to determine the dimensions
From the information given, we have the following proofs;
Width, w = x+15
Length, l = 2(x+15) - 49
Length, l = 2x + 30 - 49
Length = 2x - 19
The formula for perimeter of a rectangle is given as;
Perimeter = 2( length + width)
Substitute the expressions into the formula
Perimeter = 2 ( x+ 15 + 2x - 19 )
Perimeter = 2 (3x - 4)
Perimeter = 6x - 8
We have that the area is 162 more than 27 times the perimeter, which is Area = 27 (perimeter )+ 163
Area = 27(6x-8) + 162
Expand the bracket
Area= 162x - 216 + 162
Area = 162x - 54
But we know that
Area = length × width
Substitute the expressions
Area = (x+15)(2x-19)
Area = 2x² - 19x +30x - 285
Area = 2x² + 11x - 285
Equate the two formulas for area
162x - 54 = 2x² +11x - 285
Collect like terms
2x² + 11x - 285 - 162x + 54 = 0
2x² - 151x - 231 = 0
Solve the quadratic equation
(2x + 3)(x-77) = 0
Let's solve for x
x - 77 = 0
x = 77
The expression for the width;
Width = x+15
Width = 77 + 15
Width = 92 feet
The expression for the length
Length = 2(x+15) - 49
Length = 2 ( 77 + 15) - 49
Length = 154 + 30 - 49
Length = 184 - 49
Length = 135 feet
Thus, the measure of the length and width of the rectangle is given as 135 feet and 92 feet respectively.

What is 10z when z = 0.8
Plssss help mee
Answer:
Value of 10z = 8
Step-by-step explanation:
Given:
Equation of variable;
10z
and value of z = 0.8
Find:
Value of 10z
Computation:
We know that in given equation 10z
10 is constant(fixed value) and z is variable(changeable value)
where value of variable z is given 0.8
So,
By putting value of variable z in given equation
⇒ 10z
⇒ 10(0.8)
by multiplying variable and constant
Value of 10z = 8

Evaluate the function for an input value of 3. f(x)= −4x 2 −3x−5
Answer:
- 50
Step-by-step explanation:
x = 3
f ( x ) = - 4x^2 - 3x - 5
f ( 3 )
= - 4 ( 3 )^2 - 3 ( 3 ) - 5
= - 4 ( 9 ) - 3 ( 3 ) - 5
= - 36 - 9 - 5
= - 50
A deer weighs 13 killograms and a boa constrictor weighs 17 killograms. About How many grams heavier is the boa constrictor than the deer
Answer:
4 kilogram
Step-by-step explanation:
A deer weighs 13 kilogram
A boa constrictor weighs 17 kilogram
The weight in grans in whichj the boa constrictor is heavier than the boa can be calculated as follows
= 17-13
= 4 kilograms
Hence the boa constrictor is heavier than the boa by 4 kilogram

Answer:
Okay so you are going to get -5/12
Step-by-step explanation:
what you are going to do first is look at your signs the plus and minus signs are there to try and mix you up. What you are doing is subtracting all three of these fractions... Okay?
3/4 - 1/2 - 2/3
What you need to do is turn 1/2 into 1/4 because when adding or subtracting fractions you need to have the same denominator.
Subtract:
3/4 - 2/4 = 1/4
Now you are going to have to multiply the tops and the bottom of 2/3 by four (you should get 8/12) and multiply 1/4 (top and bottom) by three (you should get 3/12). This allows you to subtract 2/3 and 1/4 to get a product of 5/12. You can not simplify this fraction any further so you have your answer!
-5/12
*EDIT
Don't forget the minus sign.

Answer:
No i think
Step-by-step explanation:
Its going by 3, im pretty sure u cant get to 220.
Answer: No
Step-by-step explanation:
1. The pattern is +3 because
-4+3=-1
-1+3=2
2+3=5
5+3=8
2. To see if 220 is in the sequence and the starting point is -4 instead of 0, subtract 220-(-4)=224. Since 224/3 is 74.6666666667, which is not an integer, then 220 does not appear in the sequence.
