Petra takes $15 to the roller skating rink to spend on skates and food. Suppose it costs $4.75 to rent roller skates. Define a variable and write an inequality to represent the amount of money Petra can spend on food. Then solve the inequality and interpret the solution. Explain your reasoning.
The amount of money Petra can spend on food must be less than $10.25.
InequalityInequality is an expression used to how the non equal comparison of two or more numbers and variables.
Let x represent the amount of money Petra can spend on food. From the question
x + 4.75 ≤ 15
x ≤ 10.25
The amount of money Petra can spend on food must be less than $10.25.

Find the values of A and B in each triangle: show your work
Answer:
soh cah toa
to find a use sin =opp/hyp
sin 32=opp or a /hyp
sin 32*hyp=9.53
then to find b you can pythagorean theorem or just use cah or cos =adj/hyp
same process as above only using cos instead of sin
you get 15.3
then a^2+b^2=c^2
9.53^2+15.3^2=18^2 just to check or to use to find either a or b given c and either a or b

what is the percent decrease of 2,400 to 2,100?
#You times it with ×100 to get the percentage
#Part of the number/total number
2400 - 2100 = 300
300/2400 × 100 = 12.5%
So the percentage decreased is 12.5%

Two sides of a triangle measure 20 cm and 30 cm. Which of the following could be measure of the third side.
A-3cm
B-6cm
C-11cm
Answer:
11 cm
Step-by-step explanation:
the other two choices are too short
If 30 is the hypotenuse, the other two sides must exceed 30.
Answer:
C-11cm
Step-by-step explanation:
The sum of two sides of a triangle must always be bigger than the third!
3+20 is less than 30
6+20 is less than 30
11+20 is greater than 30!

Find the mZNPI
Exterior angles of triangle
Given:
The figure of a triangle.
To find:
The exterior angle of the triangle m∠NPI.
Solution:
According to the exterior angle theorem, value of exterior angle of a triangle is equal to the sum of the opposite interior angles.
Using the exterior angle theorem, we get
[tex]m\angle NPI=65^\circ+78^\circ[/tex]
[tex]m\angle NPI=143^\circ[/tex]
Therefore, the measure of angle NPI is 143 degrees.

2 (x + 3 )= -x
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
Answer:
x = -2
Step-by-step explanation:
2 (x + 3) = -x
2x + 6 = -x
- 6 -6
2x = -x - 6
+x + x
3x = -6

Find the zeros of the function.
Enter the solutions from least to greatest.
g(x) = -10x2 + 490
lesser =
greater x =
Answer:
Lesser = -490
Greater x = 100x
Step-by-step explanation:
The zeros is basically the opposite numbers to make the equation equal to 0.
We have -10x^2(I believe it's a power)
and we have + 490
so,
-10x^2 = -100x
So the opposites to make those is:
+ 100x because, -100x + 100x = 0
and -490 because, 490 - 490 = 0.

A chocolate pastry cost Rs.26 and a fruit pastry cost Rs.18 Jenny buys both
these pastries together for Rs. 500 how many of each did she buy ?
Let's assume the no. of chocolate pastry bought = x
and the no: of fruit pastry bought = y
➣ Cost of 1 chocolate pastry = Rs 26
➣ Cost of x chocolate pastry = Rs 26x
➣ Similarly, cost of fruit pastry = Rs 18 y
➣ It is given that the total cost = Rs 500
Therefore, Rs 26x + Rs 18 y = Rs 500
If we assume x = 4 and y = 22 , then
26 x 4 + 18 X 22 = Rs 500
104 + 396 = 500
⇝ No. of chocolate pastries bought = 4 ✔
⇝ No. of fruit pastries bought = 22 ✔

What is the sum of the interior
angles of a polygon that has 19
sides?
[?] degrees
Please helpppp!!!!!
Answer:
[tex]\boxed {\boxed {\sf 3060 \textdegree}}[/tex]
Step-by-step explanation:
The sum of a polygon's interior angles is found using this formula:
[tex]180 \textdegree (n-2)[/tex]
where n is the number of sides. This polygon has 19 sides.
[tex]n=19[/tex]
[tex]180 \textdegree*(19-2)[/tex]
[tex]180 \textdegree*(17)[/tex]
[tex]3060 \textdegree[/tex]
The sum of the interior angles is 3,060 degrees.

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?
Answer:
the answer is
a^2 + b^2 = c^2
5^2 + b^2 = 13^1
25 + b^2 = 169
b^2 = 144
b = 12
or
The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Answer: x - 4
The missing dimension of the prism is A
because the volume of the rectangular prism equals the product of the sides, we have:
V = (x - 1)(x - 3)A
but V = x³ - 8x² + 19x - 12
=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A
⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A
⇒ A = x - 4

Answer:
Complementary Angles: The angle with 32˚ and 48˚
Supplementary Angles: The angle that is together with the angles of 107˚ and 73˚
Neither: The angle with 101˚ and 77˚ since
Step-by-step explanation:
Complementary angles are angles that sum up to 90˚ so 32 plus 48 is 90 which makes it a complementary angle.
Supplementary angles are angles that sum up to 180˚ so 107+73 is 180 which makes it a supplementary angle.
To find the angle with "neither" Complementary nor Supplementary you use the process of elimination
