Answer:
72ft.
Step-by-step explanation:
Could be mis-understanding the problem, but if the man is 6ft tall and having a 4ft shadow, then you want to figure out how many times 4 goes into 48, which signifies how many times taller the tree is compared to the man.
48/4= 12
next you want to multiply 6 by 12, which shows exactly how tall the tree is.
6x12= 72.
Answer:
72ft
Step-by-step explanation:
so you would divide 6 and 4 and that is 1.5
then you would do 48ft x 1.5 which is 72ft
so the tree is 72ft tall

Answer:
10
Step-by-step explanation:

Answer:
Step-by-step explanation:
Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.

solve the equation for y-value and choose whether it is a direct variation or inverse variation.
xy=7
a) y=7/x direct variation
b) y=x/7 direct variation
c) y=x/7 inverse variation
d) y=7/x inverse variation
Given:
The equation is [tex]xy=7[/tex].
To find:
Whether the given equation is a direct variation or inverse variable.
Solution:
Direct variation: y is directly proportional to x.
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
Inverse variation: y is inversely proportional to x.
[tex]y\propto \dfrac{1}{x}[/tex]
[tex]y=\dfrac{k}{x}[/tex]
Where, k is the constant of proportionality.
We have,
[tex]xy=7[/tex]
Divide both sides by x.
[tex]y=\dfrac{7}{x}[/tex]
It is in the form of inverse variation.
Since [tex]y=\dfrac{7}{x}[/tex] and it is inverse variation, therefore the correct option is (d).

What is the simple interest paid to the nearest cent for each principal interest rate and time $1,000, 5%, 2 years
Step-by-step explanation:
SI=prt
p=1000
r=0.05
t=2
SI=1000×0.05×2
SI=100
The simple interest paid to the nearest cent for each principal interest rate and time $1,000, 5%, 2 years is $100.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
Given;
principle= $1000
rate= 5%
time= 2years
Substitute the given values in the formula;
Simple Interest =(1000×5×2)/100
= 10000/100
Simple Interest will be $100

the pair of figures are similar, find the missing side.
The function t relates the age of a plant fossil, in years, to the percentage, c, of carbon-14 remaining in the fossil relative to when it was alive.
t(c)=-3,970(ln c)
Use function t to complete the statements.
A fossil with 47% of its carbon-14 remaining is approximately ___ years old.
A fossil that is 7,000 years old will have approximately ___ of its carbon-14 remaining.
Applying the logarithmic function, it is found that:
A fossil with 47% of its carbon-14 remaining is approximately 2997 years old.A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.The age of a fossil with a proportion c of carbon 14 remaining is given by:
[tex]t(c) = -3970\ln{c}[/tex]
If the fossil has 47% of carbon-14 remaining, we have that [tex]c = 0.47[/tex], and thus:
[tex]t(0.47) = -3970\ln{0.47} = 2997[/tex]
For a fossil that is 7000 years old, we have that [tex]t(c) = 7000[/tex], and hence:
[tex]t(c) = -3970\ln{c}[/tex]
[tex]\ln{c} = -\frac{3970}{7000}[/tex]
[tex]e^{\ln{c}} = e^{-\frac{3970}{7000}}[/tex]
[tex]c = 0.5671[/tex]
A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.

Answer:
The answer to the question provided is Grace.
Step-by-step explanation:
The angle measure for 60 degrees and its corresponding side which measures 14 is greater than the measure of 50 degrees and its corresponding side which measures 12.4. That's correct. The reason Hector was incorrect is because the angle measure for 60 degrees and its corresponding side measured 12.4 was less than the measure of 50 degrees and its corresponding side that measured 14. 60 degrees is greater than 50 degrees, then the corresponding side for the angle that measures 60 degrees should be greater than the corresponding side for the angle that measures 50 degrees.

Which function is the inverse of f(x) = -5x -4?
Answer:
f^-1(x) = (x + 4) / -5
Step-by-step explanation:
f(x) = -5x - 4 Substitute f(x) with y
y = -5x - 4 Switch the x and y variables
x = -5y - 4 Solve it down
x + 4 = -5y
y = (x + 4)/ -5
