torisob [31]

Answer:

The number of Diplo pops D = 18

The number of sneakers S = 12

Step-by-step expla nation:

Given:

Cost of one Diplo pops = $.50

Cost of one sneakers = $.60

Total number of candies purchased = 30 pieces

cost of the number of candies purchased = $16.80

To Find:

Number of each type of candies = ?

Solution:

Let

The number of Diplo pops be D

The number of sneakers be S

Total number of candies = 30

S+D = 30

S= 30 - D--------------------------------------(1)

and cost of 30 candies is $16.80

S(0.50) + D(0.60) = 16.80----------------(2)

Substituting (1) in (2)

(30 - D)(0.50) + D(0.60) = 16.80

15 - 0.50D +0.60D = 16.80

15 + 0.10D = 16.80

0.10D = 16.80 - 15

0.10D = 1.80

D = $\frac{1.80}{0.10}$

D = 18

So the number of Diplo pops = 18

Number of sneakers S= 30 - 18 = 12

a person invested $6300 for 1 year part at 8% part at 10% and the remainder at 15%. The total annual income from these investmen

Lunna [17]

Answer:

Step-by-step explanation:

let x be part at 8%, y be part at 10% and z be part at 15%

(1) x+y+z=6300

the amount of money invested at 15% was $100 more than the amounts invested at 8% and 10% combined. so

(2) z=x+y+100

The total annual income from these investments was $766. so

0.08x+0.1y+0.15z=766 or

(3) 8x+10y+15z=76600

substitute (2) into (1)

x+y+x+y+100=6300

(4) 2x+2y=6200

substitute (2) inot (3)

8x+10y+15(x+y+100)=76600

(5) 23x+25y=75100

solving (4) n (5)

x=1200

y=1900

z=1200+1900+100=3200

Using the formula for the area of a triangle, , write an expression for the area of ΔABC. Base your answer on the work you did i

Montano1993 [528]

Answer:

$Area = \frac{1}{2} * AC * D$

Step-by-step explanation:

From the complete question, we have:

Length D to be perpendicular to side AC

So, the area of the triangle is:

$Area = \frac{1}{2} * Base * Height$

Since:

Length D is perpendicular to side AC

Then:

$Base = AC$

$Heigjt =D$

So:

$Area = \frac{1}{2} * AC * D$
