Answer: 6 cm
Step-by-step explanation:
Given: The ratio of the areas of two similar parallelograms is 4:9.
To find : The height of the bigger one if the smaller is of height 4 cm.
Let h be the height of the bigger one.
Since the areas of similar figures are proportional to the square of their corresponding sides.
Then,
Hence, the height of bigger parallelogram = 6 cm
Answer:
The length of the BM is 6 unit.
Step-by-step explanation:
Given : M is the centroid of the triangle. CM=7, PM=10, & BQ=18
To find : The value of BM ?
Solution :
Refer the attached figure below.
The centroid of a triangle is the point of intersection of its medians.
M is the centroid and the centroid divide the line in 1:2 ratio.
So, M divide BQ in 1:2 ratio and the total length of BQ is 18.
BM is one third of 18.
i.e.
Therefore, the length of the BM is 6 unit.
Answer:
Part 1 - Local Package Store 0.75 × 10 = $7.50 + $3.30 = $10.80
Nationally-Owned Package Store 0.95 × 10 = $9.50 + $3.30 = $12.80
Part 2 - Local Package Store #1 0.75 × 15 = $11.25 + $3.30 = $14.55
Nationally-Owned Package Store #2 0.95 × 15 = $14.25 + $3.30 = $17.55
Part 3 - Local Package Store #1 0.75×17 = $12.75 + $3.30 = $16.05
Nationally-Owned Package Store #2 0.95×17 = $16.15 + $3.30 = $19.45
Part 4 - 1. The Local Package Store was Cheaper for all three packages than the Nationally-Owned Package Store.
2. The Local Package Store is cheaper for the 1 pound 1 ounce package than the Nationally-Owned Package Store.
Answer:(3,0),(0-2,),(6,5)
Step-by-step explanation: BECAUSE IT MAKES ALOT OF SENSE AND UMM IM IN THE 7TH GRADED SO YEAH IF ITS WRONG THAN SORRY. :(
To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
