A biologist is comparing the growth of a population of flies per week to the number of flies a lizard will consume per week. She has devised an equation to solve for which day (x) the lizard would be able to eat the entire population. The equation is 7x = 3x + 4.

Explain to the biologist how she can solve this on a graph using a system of equations.

Answers

Answer 1

Answer:

(-1.307, 0.079), (1, 7)

Step-by-step explanation:

Given equation:

7ˣ = 3x + 4

To solve this, express each side of the equation as different function and find the intersection of graphs of those functions:

y = 7ˣy = 3x + 4

As per graph, the solution is:

(-1.307, 0.079), (1, 7)
A Biologist Is Comparing The Growth Of A Population Of Flies Per Week To The Number Of Flies A Lizard
Answer 2
7^x=3x+4

Break into two parts

y=3x+4y=7^x

Now graph and find the solution

Answer:

LA = 120 sq cm

SA = 132 sq. cm.

Step-by-step explanation:

LA = ph    where p = perimeter of the base and h = the height of prism.

Your base is a triangle.  The third side = [tex]\sqrt{5^{2} - 3^{2} }[/tex] = [tex]\sqrt{25 - 9} = \sqrt{16} = 4[/tex]

Now, the perimeter of the triangle is 3 + 4 + 5 = 12

So, LA = 12(10) = 120 sq cm

The area of the base is the area of a triangle.  A = bh/2 = 4(3)/2 = 6

SA = 2B + LA      where B is the area of the base

SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.

B, F, and the third one I don’t know (I think it’s C)

For C you only listed two lengths. For D and E there is one length that is longer than the other two lengths combined, so it can’t make a triangle. Same thing for A except for A one length is the same as the other two lengths combined.

Given : The number of side dishes for the lunch menu =6

The number of ways to select 3 dishes from 6 :

Total outcomes :                    

If applesauce and broccoli is already selected , then we need to select only one dish out of remaining 4 dishes.

Number of ways to select 1 dish from 4 :

Zoey takes out a loan of $25,000 to pay for a car. Her interest rate is 3% for 60 months. How much will Zoey pay in total for the car?

Answers

Answer: $28750

Step-by-step explanation:

Since 12 months = 1 year, it should be noted that 60 months = 60/12 = 5 years.

Simple interest = Principal × Rate × Time

= $25000 × 3% × 5

= $25000 × 0.03 × 5

= $3750

The total amount that Joey will pay for the car will be the value of the principal plus the interest which will be:

= $25000 + $3750

= $28750

Triangle ABC is similar to DEF. Which proportion can be used to find the length of DE in centimeters?

Answers

Answer:

[tex]\frac{DE}{4} = \frac{9}{3}[/tex]

[tex]DE = 12[/tex]

Step-by-step explanation:

Given

See attachment for triangles ABC and DEF

Required

The proportion to find DE

To solve for DE, we can make use of the following equivalent ratios;

[tex]AB:DE = BC:EF[/tex]

Substitute values for AB, BC and EF

[tex]4:DE = 3:9[/tex]

Express as fractions

[tex]\frac{DE}{4} = \frac{9}{3}[/tex]

The above is the proportion to solve for DE

Solving further:

[tex]\frac{DE}{4} = 3[/tex]

[tex]DE = 4 * 3[/tex]

[tex]DE = 12[/tex]

Answers

Answer:

D

Step-by-step explanation:

Básicamente  sumas esos 2 y se lo restas a 180.

Answer:

D. 86

Step-by-step explanation:

since the angles of a triangle add up to equal 180, all you have to do is add the angles you know and then find the one you don't by subtracting it from 180.

this is how it looks mathematically:

180=26+68+x

180=94+x

180-94=x

x=86
