pshichka [43]

Answer:

The number of 7th students on the Jackson Middle School basketball teams is 17 and the number of 8th students on the Jackson Middle School basketball teams is 36

Step-by-step explanation:

Let

x ----> the number of 7th students on the Jackson Middle School basketball teams

y ----> the number of 8th students on the Jackson Middle School basketball teams

we know that

There are 53 students on the Jackson Middle School basketball teams

$x+y=53$ -----> equation A

The number of 8th graders is 15 fewer than three times the number of 7th graders

$y=3x-15$ ----> equation B

substitute equation B in equation A

$x+(3x-15)=53$

solve for x

$x+3x=53+15\\4x=68\\x=17$

Find the value of y

$y=3(17)-15=36$

therefore

The number of 7th students on the Jackson Middle School basketball teams is 17 and the number of 8th students on the Jackson Middle School basketball teams is 36

Drag each tile to the correct box. Not all tiles will be used.

Zina [86]

Answer:

$1,100 at 3.2% for 3 years -> $105.60

$990 at 3.15% for 4 years -> $124.74

$1,025 at 2.8% for 5 years -> $143.5

Step-by-step explanation:

Simple interest formula is:

A = P*(1 + r*t)

where A if final account, P is principal, r is annual interest rate (as decimal) and t is time in years

Interest earned is A - P, then:

I = P*(1 + r*t) - P = P(1 + r*t - 1) = P*r*t

If P = $1100, r = 0.032 and t = 3, then:

I = 1100*0.032*3 = $105.6

If P = $990, r = 0.0315 and t = 4, then:

I = 990*0.0315*4 = $124.74

If P = $1025, r = 0.028 and t = 5, then:

I = 1025*0.028*5 = $143.5

mojhsa [17]

Answer:

${}$ XY $\overline {XY}$

Represent a distance ${}$ √

Represent a segment ${}$ √

Represent a numerical value ${}$ √

Represent a geometric figure √

Can be found by applying the ruler postulate ${}$ √

Can be be duplicated with a compass and a straight edge √

Step-by-step explanation:

The difference between XY and $\overline {XY}$ are that the points XY represents the distance between two points having a numerical value whose value can be found by using a ruler to find difference in the numbers on the ruler that coincides with the points, while

The scale is 0.25 cm: 15 km. FInd the actual distance corresponding to each map distance.

sweet-ann [11.9K]

If 0.25cm = 15 km the answer would divide 0.75 by0.25=3
next multiply 3 by 15km to get 45km
