Answer:
It depends if there is tax or not, if there isn't she can buy 8 of them.
Step-by-step explanation:
$17 is the total so we need to see how many $2 fit in $17.
8×2=16, and 16 is the closest number we can get to.

Answer:
128.57 degrees per each interior angle
Step-by-step explanation:
For interior angles of regular polygons, all you have to do is add 180 degrees to the sum for each side added. For example, from triangle to quadrilateral, you would do 180 + 180 to get 360. Then from quadrilateral to pentagon, you would do 360 + 180 = 540. Do that all the way up to a heptagon and you get a sum of 900 degrees. 900 divided by seven angles will get you 128.57 degrees per interior angle.
Answer:
each interior angle = 128.6°
Step-by-step explanation:
Sum of interior angles of a polygon with n sides = ( n - 2) x 180°
Given n = 7
So, sum of interior angles = ( 7 - 2 ) x 180 = 900°
Given it is regular,
therefore each interior angle :
[tex]\frac{900}{7} = 128.6^\circ[/tex]

A line that includes the point (4,4) has a slope of 3. What is its equation in slope-intercept
form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 3x - 8
Step-by-step explanation:
Finding the equation in point-slope form is easier. The result can then be put into slope-intercept form.
The point-slope formula is y - k = m(x - h). With the given point (h, k) being (4, 4), h = 4 and k = 4. The slope is 3. Therefore, we have:
y - 4 = 3(x - 4), or
y = 4 + 3x - 12
This simplifies to the slope-intercept form y = 3x - 8

Answer:
x=3, y=-1
Step-by-step explanation:
[tex]3x+y=8, 2x-2y=8[/tex]
Double the first equation, then add the second
6x+2y=16
+ 2x-2y=8
The y's cancel each other out.
8x=24
x=3
Solve for y
6-2y=8
2y=-2
y=-1
Double check:
6(3)+2(-1)=16
18-2=16

Hope it is helpful....In the year 2006, a person bought a new car for $18000. For each consecutive year after that, the value of the car depreciated by 15%. How much would the car be worth in the year 2009, to the nearest hundred dollars?
Please i need answer now
Answer:
Step-by-step explanation:
Use the exponential function
[tex]v(t)=a(b)^t[/tex] where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:
[tex]v(t)=18000(.85)^t[/tex] We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):
[tex]v(t)=18000(.85)^3[/tex] and simplifying a bit:
v(t) = 18000(.614125) so
v(t) = 11054.25
Round however you need to.
Which of the following shows the correct order of the given numbers?
1, 1, 1.6
the difference of two numbers is 13/24. if 11/12 of the reciprocal of one number is equal to 5/9 of the reciprocal of the other, what are the 2 numbers?
Answer:
The two numbers are 11/8 and 5/6
Step-by-step explanation:
Let the unknown numbers be x and y
Given that the difference of two numbers is 13/24
x - y = 13/24
and that 11/12 of the reciprocal of one number is equal to 5/9 of the reciprocal of the other
11/12 * 1/x = 5/9 * 1/y
11/12x = 5/9y
cross multiply
12x * 5 = 11* 9y
60x = 99y
x = 99y/60
= 33y/20
substitute into x - y = 13/24
33y/20 - y = 13/24
13y/20 = 13/24
24y = 20
y = 20/24
= 5/6
x = 33y/20
= 33 *5/20*6
= 11/8

Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted
Answer:
U = 16206 + 22.2x
Step-by-step explanation:
This year, water usage has increased by 20% for both regular days and special events.. Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted
Solution:
Last year regular usage of water was 13505 gallons, where as it was 18.5 gallons per special event. Let us assume that there were x special invents, hence:
The total usage for last year = 13505 + 18.5x
This year, the total usage (U) increased by 20%, hence:
Total usage for this year (U) = total usage for last year + 20% of total usage for last year
U = (13505 + 18.5x) + 0.2(13505 + 18.5x)
U = 13505 + 18.5x + 2701 + 3.7x
U = 16206 + 22.2x

There are 33 liters of orange juice at a school party. 1010 students want to drink all of the orange juice, and they all want to get exactly the same amount. How much orange juice can each get?
Answer: 0.033 liters or 33 ml each
Step-by-step explanation:
There are 33 liters of orange juice and 1,010 students to drink it.
If they are to drink an equal amount, you should divide the quantity of orange juice by the number of students who want to drink it:
= Quantity of orange juice / Number of students drinking
= 33 / 1,010
= 0.033 liters each
In milliliters this would be:
= 0.033 * 1,000 milliliters
= 33 ml each
Figure ABCD is a kite. Find the
value of x.
B
A 2x + 10
С
2x
D
x = [?]
Enter
Answer:
x = 20
Step-by-step explanation:
The diagonals of a kite are perpendicular to each other, so the 4 angles at the intersection are right.
The sum of the 3 angles in a triangle sum to 180° , then
2x + 2x + 10 + 90 = 180
4x + 100 = 180 ( subtract 100 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Answer:
20 is the answer

https://imgur.com/a/p0QjLGl
Answer: what’s the link about ?
From the figure, We can notice that Sum of the angles (∠AKC and ∠AKE) should be equal to 180°
Because ∠AKC and ∠AKE make a Linear Pair
⇒ ∠AKC + ∠AKE = 180°
⇒ 5x + 12x + 27 = 180
⇒ 17x = 180 - 27
⇒ 17x = 153
⇒ x = 9°
⇒ ∠AKE = 12(9) + 27 = (108 + 27) = 135°
Answer : ∠AKE = 135°
The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is , where l represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle?
7 in.
8 in.
9 in.
10 in.
Answer:
7 in
Step-by-step explanation:
Process of elimination. It can’t be 9 or 10, because 9+9=18 and 10+10=20 (they're more than 16). 8+8=16 exactly, but there’s no room in 16 for the width. Therefore, it’s 7 because 7+7=14
A sandwich shop offers 6 different types of bread, 4 different
types of meat, and 3 different types of toppings. A sandwich
is made with 1 type of bread, 1 type of meat, and 1 topping.
How many different kinds of sandwiches are there?
Answer:
36
Step-by-step explanation:
72 different kinds of sandwiches can be made using 6 different types of bread, 4 different types of meat, and 3 different types of toppings
Given :
A sandwich shop offers 6 different types of bread, 4 different types of meat, and 3 different types of toppings
bread = 6 , meat=4, toppings=3
Sandwich is made of 1 type of bread, 1 type of meat, and 1 topping.
To find the number of combinations we multiply all the possible types we have
Number of combinations of sandwiches = [tex]6 \cdot 4 \cdot 3=72[/tex]
There are 72 different kinds of sandwiches.
