<h2>
The total number of items does he buy 5 (three pens and two notebooks).</h2>
Step-by-step explanation:
The total amount spend by Mr. Loretta = $4.83
The cost of each pen = $0.95 and
The cost of each notebook = $0.99 and
To find, total number of items he buy = ?
∴ The cost of one pen and one notebook = $0.95 + $0.99 = $1.94
The cost of two pens and two notebooks = $1.94 × 2 = $3.88
∴ The cost of three pens and two notebooks = $3.88 + $0.95 = $4.83
Thus, the total number of items does he buy 5 (three pens and two notebooks).
Complete question :
Luke is designing a scale model of a clock tower. The design of the front of the tower is shown below. Obtain the area of the front face of the model.
Answer:
12500 mm²
Step-by-step explanation:
The front face of the mode consista of both triangle and rectangle
Area of rectangle :
Height * Base
Height = 200 m ; Base = 50
Area = 200 m * 50 m = 10,000 mm²
Area of triangle :
1/2 * base * height
1/2 * 50 * (300 - 200)
1/2 * 50 * 100
= 2500 mm²
Area of front face = Area of rectangle + Area of triangle
Area of front face = (10,000 + 2500) m²
Area of front face = 12500 mm²
Zeros: x = 2, x = 4
Turning point: (halfway between the zeros) x = 3, y = -1
y-intercept: where x=0, at f(0) = 8.
Axis of symmetry: the vertical line through the turning point: x = 3.
Step-by-step explanation:
- First step you take 25 on the other side and when it goes on other side it change the sign to negative 13x< -1-25
- second step you keep the sign of the bigger number then you add. The result will be 13x< -26
- third step you divide both side by 13x÷-26
- finally the answer will be -2
