Sylvia bought 4 bananas and an apple for 2.80 dollars.
How to converts dollars into cents ?1 dollars is equal to 100 cents.
To converts dollars to cents we multiply by 100 and to convert cents to dollars we divide by 100.
In the given question
Sylvia bought 4 bananas for 50 cents and 1 apple for 80 cents
So, the numerical expression will be 4 times the cost of 1 banana and 1 times the cost of an apple.
∴ 4(50) + 1(800) cents
= (200 + 80) cents
= 280 cents or (280/100) dollars = 2.80 dollars.

Answer:
[tex]a {b}^{3} \sqrt[4]{5} [/tex]
The graph shows the distance, y, that a car traveled in x hours:
A graph is shown with the x-axis title as Time in hours. The title on the y-axis is Distance Traveled in miles. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 375 in increments of 75 for each grid line. A line is shown connecting ordered pairs 1, 75 and 2, 150 and 3, 225 and 4, 300. The title of the graph is Rate of Travel.
What is the rate of change for the relationship represented in the graph? (1 point)
A) fraction 1 over 150
B) fraction 1 over 75
C) 75
D) 150
The speed of the car is 75 mph
===========================================================
Explanation:
The four given points on the diagonal line are:
(1,75)(2,150)(3,225)(4,300)Pick any two points from that list of four. I'll pick the first two points. The coordinates are then plugged into the slope formula below
m = (y2-y1)/(x2-x1)
m = (150-75)/(2-1)
m = 75/1
m = 75 so the answer is choice C
The rate of change of 75 means that each time x goes up by 1, y increases by 75.
For each hour that passes, the car has traveled 75 miles. Therefore, the rate of change is 75 miles per hour.
-----------
Note how,
slope = rise/run = (change in y)/(change in x)change in y = change in distancechange in x = change in timespeed = (change in distance)/(change in time)In short, the slope represents the speed of the car. If the line remains the same slope, then the speed is constant.

Answer:
63. Perimeter: 60.4 units
Area: 126.14 units²
64. x = 8
m = 62⁰
Step-by-step explanation:
First, let us solve question 63. To find the perimeter and the area of the triangle, we will first find the x and y value.
Formulas we would use to find the answer in Q. 63 :-
Cos = opposite / hypotenuse
Sin = adjacent / hypotenuse
Area = 1/2 × b × h
Perimeter = adding all sides
Let us find the y value using the formula of Cos.
Cos = opposite / hypotenuse
Cos24⁰ = y / 26
26(Cos24⁰) = (y / 26)26
26(Cos24⁰) = y
23.8 = y ---> *since it said to round to the nearest hundredth.*
Now let us find the x value by using the formula of Sin.
Sin = adjacent / hypotenuse
Sin24⁰ = x / 26
26(Sin24⁰) = (x / 26)26
26(Sin24⁰) = x
10.6 = x ---> *since it said to round to the nearest hundredth.*
Now let us find the perimeter and the area.
Area = 1/2 × b × h
Area = 1/2 × 10.6 × 23.8
Area = 126.14 units²
Perimeter = adding all sides.
Perimeter = 26 + 23.8 + 10.6
Perimeter = 60.4 units
On to Q. 64. Formulas we would use to find the answer of Q. 64 is :-
Tan = opposite / adjacent
Sin = opposite / hypotenuse
Let us find m. In order to find m, we will use the Sin formula.
Sin = opposite / hypotenuse
Sinm⁰ = 15 / 17
m⁰ = sin-1(15 / 17)
m⁰ = 62 ---> *since it said to round to the nearest whole number.*
Now let us find x by using the formula of Tan.
Tan = opposite / adjacent
Tan62⁰ = 15 / x
x(Tan62⁰) = (15 / x)x
x(Tan62⁰) = 15
x(Tan62⁰) / Tan62⁰ = 15 / Tan62⁰
x = 15 / Tan62⁰
x = 8 ---> *since it said to round to the nearest whole number.*

What is the area of the figure at the right?
Answer:
88 in
Step-by-step explanation:
find the area of each shape individually
triangles - 3x8=24 and you don't have to divide by 2 because there's 2 triangles.
rectangles - 8x4x2=64 you multiply by 2 because there are 2 rectangles.
then you add the rectangles and triangles together.
Answer:
88 (is the total area since I did not really get what you were asking)
Step-by-step explanation:
The question is basically asking to find the rectangle and triangle and then multiply both by 2.
Find the rectangle:
4 x 8 = 32
Find the triangle:
7 - 4 = 3
3 x 8/2 = 12
Multiply by 2:
32 x 2 = 64
12 x 2 = 24
Add the two up..
64 + 24 = 88

Pqr is an isosceles triangle and prs is a straight line
Answer:
∠ QRS = 132°
Step-by-step explanation:
Since the triangle is isosceles then the 2 base angles are congruent, that is
∠ PQR = ∠ PRQ = [tex]\frac{180-84}{2}[/tex] = [tex]\frac{96}{2}[/tex] = 48°
∠ PRQ and ∠ QRS are adjacent angles , so
∠ QRS = 180° - 48° = 132°
