Write and evaluate the expression. Then, select the correct answer. ten times the sum of seven and a number;
evaluate when j = 1

A 2-column table with 5 rows. Column 1 is labeled Key Words with entries ten, times, the sum of, seven, a number. Column 2 is labeled Replace with entries 10, times, (+), 7, j.

10 × 7 + j; when j = 1, the value is 71
7(10 + j); when j = 1, the value is 77
10(7 – j); when j = 1, the value is 60
10(7 + j); when j = 1, the value is 80

The correct option is:

10(7+j); when j=1, the value is 80.

Step-by-step explanation:

Let 'j' is the number

Ten times the sum of seven and a number means:

When j=1, the expression becomes

Hence, the value of the expression at j=1 is 80.

i.e.

Therefore, the 4th option is the correct answer.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
