Answer:
No, because 6+8=15 is not true
Answer:
The number of 1/5 liter glasses that Lin can fill is ![7\frac{1}{2}](https://tex.z-dn.net/?f=7%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
we know that
To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5
so
![1\frac{1}{2} :\frac{1}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%20%3A%5Cfrac%7B1%7D%7B5%7D)
Convert mixed number to an improper fraction
![1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%3D1%5Cfrac%7B1%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D)
substitute
![\frac{3}{2} :\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20%3A%5Cfrac%7B1%7D%7B5%7D)
Multiply in cross
![\frac{5*3}{2*1}=\frac{15}{2}=7.5](https://tex.z-dn.net/?f=%5Cfrac%7B5%2A3%7D%7B2%2A1%7D%3D%5Cfrac%7B15%7D%7B2%7D%3D7.5)
Convert to mixed number
![7.5=7+\frac{1}{2}=7\frac{1}{2}](https://tex.z-dn.net/?f=7.5%3D7%2B%5Cfrac%7B1%7D%7B2%7D%3D7%5Cfrac%7B1%7D%7B2%7D)
Answer:
10 squared units
Step-by-step explanation:
This triangle is pretty easy since it creates a right triangle. So the base length and height length are pretty easy to identify.
The area of a triangle is .5*base*height.
The base length after drawing the points is a horizontal so just count it or do 4-0=4.
The height length after drawing the points is a vertical so just count it or do 4-(-1)=4+1=5.
So the area of the triangle is .5*4*5=.5(20)=10 units squared.
Now if you didn't fill like drawing it and you knew how to find the determinant.
You just compute
.5 times det| 0 -1 1 |
| 0 4 1 |
| 4 -1 1 |
.5[ 0 det| 4 1 | - -1 det| 0 1 | + 1 det | 0 4 | ]
| -1 1 | | 4 1 | | 4 -1 |
.5[ 0 - -1(0-4) + 1(0-16)]
.5[ 0 -4 -16]
.5[-20]
-10
And if you get a negative just take the absolute value of it giving you 10.
Answer:
1,2,3,
Step-by-step explanation:
Answer:
Solution given:
angle of elevation [A]=29°
height [p]=?
base[b]=400ft
since
relationship between base and height is given by Tan angle
we have
Tan 29°=opposite/adjacent
Tan29°=perpendicular [P]/base[b]=P/400
P=Tan29*400
P=221.72ft
