Answer:
BOTH ARE CORRECT
Step-by-step explanation:
Given that:
Triangle ABC Is right angled ;Angle ABC
Hypotenus = 15
If legs are 9 and 12 units long ;
From Pythagoras :
9² + 12² = hypotenus²
81 + 144 = 225²
2.) if:
B = 20° ; BC = will be
Using :
Cos θ = BC / 15
Cos 20 = BC / 15
BC = Cos 20 * 15
BC = 0.939692 * 15
BC = 14.09
BC = 14.1
( iready math ) Macy's aunt makes raspberry jam using 6 tablespoons of sugar and 8 tablespoons of raspberries. What is the ratio of tablespoons of raspberries to tablespoons of sugar?
8 to 14
8 to 6
6 to 14
6 to 8
Answer:
8 to 6
Step-by-step explanation:
The question is asking what is the ratio of "tablespoons of raspberries" TO ratio of "tablespoons of sugars".
= 8 tablespoons of raspberries TO 6 tablespoons of sugar
= 8 (tablespoons of raspberries) TO 6 (tablespoons of sugar)
= 8 TO 6
The ratio of tablespoons of raspberries to tablespoons of sugar should be considered as the 8 to 6.
Calculation of the ratio:Since Macy's aunt makes raspberry jam using 6 tablespoons of sugar and 8 tablespoons of raspberries.

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid).The building has a 64 × 64 m square base and is 36 m tall. The cut off section has a 16 × 16 m, square base and is 12 m tall. What is the volume of the buliding?
Answer:
65,536−1,024
which = 64,512 m^3
Step-by-step explanation:
I took the test!
The volume of the building shaped like a pyramid that's cut off in a plane parallel to its base is 64512 m³
Volume of a pyramidvolume of a pyramid = 1 / 3 Bh
where
B = base areah = height of the pyramidTherefore,
volume of the building = volume of the whole figure - volume of the cut part
volume of the whole figure = 1 / 3 × (64 × 64) × (12 + 36)
volume of the whole figure = 65536 m³
volume of the cut part = 1 / 3 × (16 × 16) × (12)
volume of the cut part = 1024 m³
Therefore,
volume of the building = 65536 - 1024 = 64512 m³

A remodeling project calls for sanding a chair with a disk sander. The sanding disk used on the sander has a radius of 4 inches. Find the area of the disk. Use 3.14 for \large \pi
Answer:
the area of the disk is 50.24 inches^2
Step-by-step explanation:
The computation of the area of the disk is as follows:
As we know that
The area of the circle is
= πr^2
= 3.14 × 4^2
= 3.14 × 16
= 50.24 inches ^2
hence, the area of the disk is 50.24 inches^2

x = 70°, y = 30°, z = 20°
Step-by-step explanation:
Right triangle have a total internal angle of 180°.
x = 180° - 110°
= 70°
z = 180° - 90° - x
= 180° - 90° - 70°
= 20°
y = 180° - 40° - 90° - z
= 180° - 40° - 90° - 20°
= 30°

e. 19.8
Step-by-step explanation:
Hope this helped!
Answer:
a. 18 b. 15/64 c. 122 2/9 d. 157.5615 e. 19.8
Step-by-step explanation:
a.
b. multiply across, so 1 * 15 = 15, 4*16=64, 15/64 can't be reduced, so done
c. 13 3/4 * 7 8/9, you must convert to improper fractions to multiply
4*13+3 = 55 so the first part is 55/4, 7*9+8=80 so the second is 80/9
55/4 * 80/9 = (55*80) / (4*9) = 4400 / 36, both are divisible by 4 so can be reduced to 1100/9 which cannot be reduced any further, 1100 + 9 = 122 R 2 so
1100/9 = 122 2/9
d. used calculator
e. 33% of 60 = (33//100)*(60/1) = (33*60) / (100*1) = 1980 / 100 = 19.8

Hassan plotted point M in the coordinate plane below.
On a coordinate plane, Point M is 0.5 units to the left and 0.25 units down.
He says that the plotted point is (0.5, 0.25). What is Hassan’s error?
The x- and y-coordinates are switched.
Both coordinates should be negative.
The x-coordinate should be -2.
The y-coordinate should be -1.
Answer:
Both coordinates should be negative
Step-by-step explanation:
When you go to plot a point, you always start at (0,0). Since you go left 0.5 units, that would put you at -0.5, then you go down 0.25 units which would put you at (-0.5, -0.25). The result would be (-0.5, -0.25). Hope this helps! :)

Suppose your school costs for this term were $4780 and financial aid covered 3/4 of that amount. How much did financial aid cover? How much do you still have to pay?
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195
