Answer:
x = 128°
Step-by-step explanation:
123 + 109 + x = 360
x = 360 - (123 + 109)
x = 360 - 232
x = 128°
Answer:
x y
8 4
14 7
6 3
Step-by-step explanation:
Step 1: Substitute x value into equation for y
y = 8/2
y = 4
y = 14/2
y = 7
Step 2: Substitute y value into equation for x
3 = x/2
6 = x
Therefore the ordered pairs are (8,4) (14,7) (6,3)
Answer:
You can use Pythagoras theorem to calculate x:
12² + 14² = x²
144 + 196 = x²
x² = 340
x = √340 ≈ 18,44
Answer:
The total weight of bread in pounds is 7.5 lbs. The total weight of bread in ounces is 120 oz.
Step-by-step explanation:
1 1/4 * 6
= 5/4 * 6
= 15/2
= 7.5 pounds
7.5 * 16 = 120 ounces [ 1 pound = 16 ounces ]
Answer:
Since figure is not given, assume drawing a rectangle and label it from left top to right top as A and B. Similarly label it as C and D from bottom left to right. Draw a semicircle starting from C to D inside the rectangle.
You are asked to find area of shaded region which I assume is semicircular part.
Area of a circle is determined by Pi × r ^2
r is the radius of circle which is half of diameter. The diameter of circle is same as width of rectangle. So radius = 7/2 = 3.5 mm And area of shaded region is
1/2(Pi×r^2) = 1/2(3.14×3.5^2) = 19.2325 sq mm
