Answer:
76
Step-by-step explanation:
so first the equation for the situation has been given which is
194=1/2x + 2x - 16
now you can just solve since it's a linear equation
194=2.5x -16
take 16 to the other side to get
210=2.5x
solve to get x (adult price)
which is 84
remember the. child's price is 8 less
84-8=76
Deshaun and Isabel each have opened a savings account today. Deshaun opened her account with starting amount of $590 and she'll take out $35 each month Isabel opened here with a start of $790 and she'll take out $55 per month (A) For each account write an expression for the amount of zkids in the account after x months (B) Write an equation to show when the two accounts would have the same amount of money
Answer:
Deshaun = $590 - $35x
Isabel : $790 - $55x
$590 - $35x = $790 - $55x
Step-by-step explanation:
For Deshaun :
Amount in her account = $590
Amount she would have withdrawn by month x = $35 × x = $35x
The amount she would have in her account = $590 - $35x
For Isabel :
Amount in her account = $790
Amount she would have withdrawn by month x = $55 × x = $55x
The amount she would have in her account = $790 - $55x
Let x be the time when the money in their account would be equal =
$590 - $35x = $790 - $55x
the diagonal of a square is x what is the perimeter of the square
Answer:
2[tex]\sqrt{2}[/tex] x
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and hypotenuse x
Using Pythagoras' identity on one of the right triangles, then
s² + s² = x²
2s² = x² ( divide both sides by 2 )
s² = [tex]\frac{x^2}{2}[/tex] ( take the square root of both sides )
s = [tex]\sqrt{\frac{x^2}{2} }[/tex] = [tex]\frac{x}{\sqrt{2} }[/tex]
Thus
perimeter = 4s = 4 × [tex]\frac{x}{\sqrt{2} }[/tex] = [tex]\frac{4x}{\sqrt{2} }[/tex]
Multiply numerator/ denominator by [tex]\sqrt{2}[/tex]
perimeter = [tex]\frac{4x\sqrt{2} }{2}[/tex] = 2[tex]\sqrt{2}[/tex] x

Step-by-step explanation:
The members of a cooking club are making cakes, which they will sell at a street fair for $9 apiece. It cost $50 for a booth at the fair, and the ingredients for each cake cost $4. At some point, the club members will sell enough cakes so that their sales cover their expenditures. How much will the sales and expenditures be?
Answer:
Sales= $90
Expenditures= $90
Step-by-step explanation:
The members of a cooking club are making cakes.
The cakes will be sold at a street fair price of $9 for each cake.
It cost $50 for a booth at the fair.
The ingredients for each cake cost $4
Let y represent the number of cakes that was sold
Since the price of each cake is $9 then,
Sales = $9y
Since the booth cost $50 and ingredients cost $4 then,
Expenditures = $50 + $4y
Sales = Expenditures
9y= 50 + 4y
Collect the like terms
9y-4y= 50
5y= 50
Divide both sides by the coefficient of y which is 5
5y/5= 50/5
y= 10
Sales= 9×10
= $90
Expenditures= $50 + 4(10)
= $50+$40
= $90
Hence the sales is $90 and the expenditures is $90
A circle has a circumference of 50.24 units.
What is the radius of the circle?
units
Show Calculator
Answer:
radius = 8 unitsStep-by-step explanation:
Circumference of a circle = 2πr
where
r is the radius
From the question
Circumference = 50.24 units
To find the radius substitute the value into the above formula and solve for the radius
That's
[tex]50.24 = 2\pi \: r[/tex]
Divide both sides by 2π
We have
[tex]r = \frac{50.24}{2\pi} [/tex]
r = 7.9959
We have the final answer as
radius = 8 unitsHope this helps you
Answer:
8 units
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
50.24 = 2 * pi * r
Using 3.14 to approximate pi
50.24 = 2 * 3.14 * r
50.24 = 6.28 r
Divide each side by 6.28
50.24/6.28 = r
8 = r

40% of one spig is a spoog. 25% of a speeg is a spoog. 70% of a speeg is a spug. What percent of 1 spig is 5 spugs
The percentage of 1 spig to 5 spug is 17.9%
What is percentage?
Percentages are essentially fractions where the denominator is 100.
40% of spig =1spoog
25% of speeg = 1 spoog
therefore 40%spig = 25% speeg
1 spig = 25/40 speeg
1 spig = 5/8 speeg
70% of speeg= 1 spug
70/100 speeg = 1 spug
therefore dividing both sides by 100/70
1 speeg = 100/70spug = 10/7spug
similarly 8/5 spig = 1 speeg
therefore 8/5 spig = 10/7 spug
divide both sides by 5/8
1 spig = 50/56 spug
percentage of 1 spig to spug =
89.3 % spug is 1 spig
therefore the percentage of 1 spig of 5 spugs is 89.3% /5 = 17.9%

Answer:
Choose f(x) = 11x + 1
Step-by-step explanation:
Note that we will simply plug the value of 2 into the equation for February:
f(2) = 11(2) + 1 = 23
And plug the value of 6 into the equation for June:
f(6) = 11(6) + 1 = 67
Note how the points on the graph seem to match up with these values. If we evaluate following the same style for each:
f(3) = 11(3) + 1 = 34
f(4) = 11(4) + 1 = 45
f(5) = 11(5) + 1 = 56
Note, these values seems to be very close in approximation to the graph points for each month.
The other three functions return values that are just to far away from what are represented in the graph.

Answer:
The four angles are;
30 degrees, 85 degrees, 95 degrees , and 150 degrees
Step-by-step explanation:
Call the four angles of this quadrilateral A, B, C, and X (being X the smallest angle)
Then angle A is 55 degrees larger than X , therefore we can write it as X+55
Angle B is 65 degrees larger than X , therefore we can write it as X+65
Angle C is 120 degrees larger than X , therefore we can write it as X+120
Then we know that the addition of all four angles of a quadrilateral must give 360 degrees , so we have:
X + X + 55 +X + 65 + X + 120 = 360
that is:
4 X + 240 = 360
4 X = 360 -240
4 X = 120
X = 120/4
X = 30 degrees
and the other angles are:
30 + 55 = 85 degrees
30 + 65 = 95 degrees
30 + 120 = 150 degrees
I NEED THIS ANSWER ASAP!!!! The height of tower A is 644 feet more than tower B. The two towers have a combined height of 1590 feet. What are the heights of each tower?
Answer: oop ;-;
Step-by-step explanation: We have two basic equations
A = B + 826 A is 826ft taller than B
A + B = 1516 Combined height is 1516 ft
Replace A with B+826 in 2nd equation and solve for B
B + 826 + B = 1516 Combine like terms
2B + 826 = 1516 Subtract 826 from both sides
2B = 690 Divide both sides by 2
B = 690/2
B = 345 ft
We know that A = B + 826 so you simply need to do
that addition to have the height of both towers.

Some 5th grade boys are playing with sugar cubes. Each sugar cube measures 1x1x1 cm. The box is 5 cm long,10 cm high and 12 cm wide. How many sugar cubes can fit in the box
Answer:
Number of sugar cubes fit in box = 600 sugar cube
Step-by-step explanation:
Given:
Size of sugar cube = 1 x 1 x 1 cm
Size of box.
Length = 5 cm
Width = 12 cm
Height = 10
Find:
Number of sugar cubes fit in box
Computation:
Volume of sugar cube = 1 x 1 x 1
Volume of sugar cube = 1 cm³
Volume of box = 5 x 10 x 12
Volume of box = 600 cm³
Number of sugar cubes fit in box = Volume of box / Volume of sugar cube
Number of sugar cubes fit in box = 600 / 1
Number of sugar cubes fit in box = 600 sugar cube
