Answer:
7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 > 73.293
Step-by-step explanation:
Given: Numbers are 7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 and 73.293
To compare: the two given numbers
Solution:
7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 is equal to ![73.385](https://tex.z-dn.net/?f=73.385)
Compare the numbers
and 73.293
Digits at the ones pace and tens place in both the numbers are same.
Observe the digit at the tenth place in both the numbers.
Digit at the tenth place in 73.385 is 3
Digit at the tenth place in 73.293 is 2
As
,
73.385 > 73.293
So,
7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 > 73.293
Answer:
10
Step-by-step explanation:
Raisin = r
blueberry = b
banana = n
r = 18
b = 3r = 18 x 3 = 54
n = b/2 = 54 / 2 = 27
total = 18+54+27 = 99
Answer:
Option B is true
Step-by-step explanation:
We are given that three right triangles .Triangles ABD,CAD and CBA are similar.
When two triangles are similar then, the corresponding sidea are in equal proportion.
We have AB=5 units
AC= 7 units
BC=x
Triangles ABD is similar triangle CBA
![\frac{AB}{BD}=\frac{BC}{AB}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BBD%7D%3D%5Cfrac%7BBC%7D%7BAB%7D)
![AB^2=BC\cdot BD](https://tex.z-dn.net/?f=AB%5E2%3DBC%5Ccdot%20BD)
![(5)^2=BC\cdot BD](https://tex.z-dn.net/?f=%285%29%5E2%3DBC%5Ccdot%20BD)
![BC\cdot BD=25](https://tex.z-dn.net/?f=BC%5Ccdot%20BD%3D25)
When triangle CAD and CBA are similar
Then,![\frac{AC}{BC}=\frac{CD}{AC}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BBC%7D%3D%5Cfrac%7BCD%7D%7BAC%7D)
![AC^2=CD\cdot BC](https://tex.z-dn.net/?f=AC%5E2%3DCD%5Ccdot%20BC)
![(7)^2=CD\cdot BC](https://tex.z-dn.net/?f=%287%29%5E2%3DCD%5Ccdot%20BC)
![49=CD\cdot BC](https://tex.z-dn.net/?f=49%3DCD%5Ccdot%20BC)
In traingle CBA, uisng pythagoras theorem
![AB^2+AC^2=BC^2](https://tex.z-dn.net/?f=AB%5E2%2BAC%5E2%3DBC%5E2)
![BC\cdot BD+BC\cdot CD=x^2](https://tex.z-dn.net/?f=BC%5Ccdot%20BD%2BBC%5Ccdot%20CD%3Dx%5E2)
![25+49=x^2](https://tex.z-dn.net/?f=25%2B49%3Dx%5E2)
![x^2=74](https://tex.z-dn.net/?f=x%5E2%3D74)
Hence, option B is true.
3.) $ 9.75| First you multiply 2.25 by 3, then 1.75 by 2 and add them together which gives you 10.25. Finally you subtract 10.25 from 20 which gives you 9.75
