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.

Answer:

x=20

Step-by-step explanation:

Well just cross multiply if its easier

x(3)=3x

12*5=60

60=3x

x=20

Answer:

C

Answer:

7 days

Step-by-step explanation:

We need to find bracelets per day.

1 day 2 days

5 bracelets 10 bracelets

since we know how many bracelets she can make per day, all we have to do is divide 35 by 5.

to get 7 days.

Step-by-step explanation:

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 :

Favorable outcomes:  

Now, the theoretical probability that applesauce and broccoli will both be offered on Monday :-

Hence, the theoretical probability that applesauce and broccoli will both be offered on Monday = 0.20

Answer:

[tex]\sqrt{260\\[/tex] or 16.12

Step-by-step explanation:

distance formula is [tex]} d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

Distance (d) = √(9 - 1)2 + (9 - -5)2

= √(8)2 + (14)2

= √260

= 2√65

= 16.124515496597

Answer:

44

Step-by-step explanation: mean is the average so add 55, 37, 8, 50, 60, 50, 48 and you get 308 then divide 308 by how many numbers you added which is 7, so 308 divided by 7 is 44 which is the answer

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.

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

Question 13 is the third one. Number 15 is the second one.

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

[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]
