AABC ~ AXYZ

gayaneshka [121]

Answer:

s = 10

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

$\frac{AB}{XY}$ = $\frac{BC}{YZ}$ ( substitute values )

$\frac{8}{4}$ = $\frac{s}{5}$ ( cross- multiply )

4s = 40 ( divide both sides by 4 )

s = 10

Someone please help me thank you

Answer:

x = - 1

Step-by-step explanation:

Given

4x = x^2 - 5 Transfer 4x to the right side.

Solution

x^2 - 4x - 5 = 0 Factor

(x - 5)(x + 1)

You want the negative solution. That means that the middle sign must be plus.

x + 1 = 0 Subtract 10 from both sides

x = - 1 Ten on the left disappears by the subtraction process.

Is that correct?

4x = x^2 - 5

x = - 10

4*(-1) = (-1)^2 - 5

-4 = ? 1 - 5

-4 = - 4

and it does work.

A snack food manufacturer buys corn for tortilla chips from two cooperatives, one in Iowa and one in Illinois. The price per uni

aleksandrvk [35]

Answer:

a. x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Min 6x1 + 5.5x2

c. x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000

Step-by-step explanation:

a. We can consider the variables x1 and x2 as:

x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Price per unit of Iowa corn = $6

Price per unit of Illinois corn = $5.5

Objective function that would minimize the total cost can be written as:

Min 6x1 + 5.5x2

c. The manufacturer needs at least 12000 units of corn which means that the combined number of units from Iowa and Illinois must be greater than or equal to 12000. So, we can write:

x1 + x2 ≥ 12000

The Iowa cooperative can supply up to 8000 units which means that the value of x1 must not be greater than 8000. So, we can write:

x1 ≤ 8000

Similarly, the Illinois cooperative can supply at least 6000 units which means that the value of x2 must not be less than 6000. So, we can write:

x2 ≥ 6000.

The constraints for these conditions are:

x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000
