4. This is simple the answer would be C. 60 because if you divide 9 by 1.50 you would get 6, so then you would need to multiply 6 by the number of erasers which is 10. So, 6 times 10 is 60.

5. This answer would be A. 1700 because (17 x 4) is 68 and 68 times 25 is 1700.

Hoped this helped!

The answer is A because you need to multiply 17*4 frist then times it by 25.

The function g(n) = n2 − 16n + 69 represents a parabola.

miss Akunina [59]

Hello :
g(n) = n2 − 16n + 69
=( n²-16n+64)-64 +69.....( completing the square)
g(n) = (n-8)² +5...... (the vertex form)
the vertex is : (8,5)
the axis of symmetry is the line : n = 1

Answer:

Step-by-step explanation:

The attached photo shows the diagram of quadrilateral QRST with more illustrations.

Line RT divides the quadrilateral into 2 congruent triangles QRT and SRT. The sum of the angles in each triangle is 180 degrees(98 + 50 + 32)

The area of the quadrilateral = 2 × area of triangle QRT = 2 × area of triangle SRT

Using sine rule,

q/SinQ = t/SinT = r/SinR

24/sin98 = QT/sin50

QT = r = sin50 × 24.24 = 18.57

Also

24/sin98 = QR/sin32

QR = t = sin32 × 24.24 = 12.84

Let us find area of triangle QRT

Area of a triangle

= 1/2 abSinC = 1/2 rtSinQ

Area of triangle QRT

= 1/2 × 18.57 × 12.84Sin98

= 118.06

Therefore, area of quadrilateral QRST = 2 × 118.06 = 236.12

When 1 is subtracted from three- tenths of the number, the result is equal to one-fifth of a number. What is the number

Bas_tet [7]

Based on the given mathematical statement, it can be rewritten into a mathematical equation to simplify and to be solved easily. The statement, "When one is subtracted from three-tenths of a number" corresponds to the equation, 3x/10 - 1, that is assuming the number is represented by the variable x. This is equal to one-fifth of the number. In other words,
3x/10 - 1 = x/5
x = 10
