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

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:

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

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.

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:

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

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

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
