Answer:

60ft

Step-by-step explanation:

DC is 50% longer than BD (given)

BD is 40ft (given)

DC is 50% longer than BD this means that DC= BD+50% of  BD

40ft +50/100 * 40

=40ft +20ft

=60ft

Another way to solve this could be DC is 150%of BD as BD =40ft=100% of it's length.

So, 150/100 *40

=60ft

Answer:

y = x + 3 is red line.

y = -3x-2 is green line.

y = -x-7 is black line.

y = 2x + 1 is blue line.

Step-by-step explanation:

first we look at up on both  and y intercepts

then find a line.

y = x + 3

x intercept is : x + 3 = 0 so x = -3

y intercept is : 0 + 3 = 0 so y = 3

y = -3x-2

x intercept is : -3x-2 = 0 so x = -2/3

y intercept is : -3*0 -2 = 0 so y = -2

y = -x-7

x intercept is : -x -7 = 0 so x = -7

y intercept is : 0  -7 = 0 so y = -7

y = 2x+ 1

x intercept is : 2x+1 = 0 so x = -1/2

y intercept is : 0*2 + 1 = 0 so y = 1

therefor :

Answer:

y = x + 3 is red line.

y = -3x-2 is green line.

y = -x-7 is black line.

y = 2x + 1 is blue line.

Rita finds the quotient of 584 divide by 17
Serga [27]

Answer:

Rita's answer in incorrect because the remainder that Rita got which is 23 is greater 17 which is the divisor. 17 can still go in 23 1time to have a remainder of 6. Hence Rita's answer is wrong with 34R6 being the correct answer.

Step-by-step explanation:

Quotient is the required answer if 584 is divided by 17

584 will be the dividend and 17 is the divisor.

To calculate 584/17, 17 will go in 58 3times with 7 as remainder. This remainder 7 will combine with 4 to make 74, 17 will also go in 74 4times with remainder of 6.

The final answer by combining the number of times 17 goes in 584 which is 34 with final remainder of 6. This means that;

584/17 = 34 remainder 6 i.e 34R6

This shows that Rita's answer in incorrect because the remainder that Rita got which is 23 is greater 17 which is the divisor. 17 can still go in 23 1time to have a remainder of 6. Hence Rita's answer is wrong with 34R6 being the correct answer.
