Ms.Maxwell bought a purse with 1/4 of her money. The purse cost $37.00. How much money did Ms.Maxwell have left after she bought the purse?
Answer:
the money left after purchasing the purse is $111
Step-by-step explanation:
The computation of the money left after purchasing the purse is given below:
Since in the question it is mentioned that she bought a purchase with one-fourth of money
And, the purse cost is $37
So the amount left would be
= $37 × (3 ÷ 4) ÷ (1 ÷ 4)
= $37 × 0.75 ÷ 0.25
= $111
Hence, the money left after purchasing the purse is $111

The ratio of teachers to students at Priory School is 2:27
What is school's total population if there are 42 staff
Answer:
609
Step-by-step explanation:
ratio of teachers to students at Priory School =2:27
Let X= total number of both the students and the teacher
Ratio of teacher=( 2/29)X
Ratio of student is (27/29 )X
But total number of teacher = 42
2/29 ×X =42
2X= 42×29
2X=1218
X= 609
Hence, school's total population is 609

A taxi charges a flat fee of $3.00, plus an additional $1.25 per mile. Antonio can spend no more than $18. Choose the inequality that represents the number of miles he can ride, an describes the solution set.
Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles
Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤
and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.

The measure of angle PST 129 degrees after applying the properties of the triangle.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is given that:
The triangle is shown in the picture.
The equation can be made:
5x - 9 = (180 - (11x - 3))
5x + 11x = 180 + 3 + 9
16x = 192
x = 192/16 = 12
The measure of angle PST = 11x - 3
= 11(12) - 3
= 129 degrees
Thus, the measure of angle PST is 129 degrees after applying the properties of the triangle.

Answer:
x can be any value (infinite number of solutions)
Step-by-step explanation:
The equation simplifies to ...
2(x -2) +3 = 2x -1
2x -4 +3 = 2x -1
2x -1 = 2x -1
This is true for every value of x. There are an infinite number of solutions.
ANSWER TO 4 AND 5 PLEASE ASAP
Answer:
4) 2/6 or 1/3
5) 42/110 or 21/55
Step-by-step explanation:
4) there are two red options out of a total of 6 options, so 2/6
5) 7 red out of total of 11, so 7/11 · 6/10 = 42/110
To get the fraction 6/10:
we reduce 7 to 6 because there is one less red than originally
we reduce 11 to 10 because there is one less from the initial total

Use the Law of Cosines to solve for the side BC. Round your answer to the point
nearest whole number. Write the value only *
Answer:
BC = 50
Step-by-step explanation:
Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cosy (c is BC)
c^2 = 30^2 + 21^2 - 2(30)(21)cos123
c^2 = 900 + 441 - 1260*(-0.888)
c^2 = 1341 - (-1118.841)
c^2 = 2459.841
c = 49.597
c = 50

Opens up or down, Vertex: (-10, -1), Passes through: (-8, -5)
Answer:
opens down
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) - (- 10, - 1 ) , then
y = a(x + 10)² - 1
To find a substitute (- 8, - 5) into the equation
- 5 = a(- 8 + 10)² - 1 ( add 1 to both sides )
- 4 = a(2)² = 4a ( divide both sides by 4 )
- 1 = a
y = - (x - 10)² - 1 ← equation in vertex form
To determine if it opens up/ down consider the value of a
• If a > 0 then curve opens up
• If a < 0 then curve opens down
Here a = - 1 < 0 then curve opens down
