Evaluate h(d) =4/9d+6 2/3 for d=3 A. 8 B. 7 C.7 1/3 D. 2 2/3

Mathematics

For this case we have a function of the form y = h (d). Where:

h (d) = \frac {4} {9} d + 6 \frac {2} {3}

Rewriting the mixed number as a fraction:

h (d) = \frac {4} {9} d + \frac {3 * 6 + 2} {3}\\h (d) = \frac {4} {9} d + \frac {20} {3}

Substituting d = 3:

h (3) = \frac {4} {9} (3) + \frac {20} {3}\\h (3) = \frac {4} {3} + \frac {20} {3}\\h (3) = \frac {24} {3}\\h (3) = 8

ANswer:

Option A

Tickets to the school play are $10 for adults, $4 for students and $3 for senior citizens. There were 670 tickets sold for Thurs
joja [24]

Answer:

500

105

Step-by-step explanation:

This question would be solved using a simultaneous equation

let

a = number of adults who bought the ticket

b = number of students who bought the ticket

c = number of senior citizens who bought the ticket

a + b + c = 670 eqn 1

10a + 4b + 3c = 5615 -- eqn 2

If 65 senior citizen bought the ticket, substitute for c in equation 1 and 2

a + b + 65 = 670

a + b = 670 - 65

a + b = 605 eqn 3

10a + 4b + 3(65) = 5615

10a +4b = 5420 eqn 4

multiply equation 3 by 10 to derive equation 5. Subtract eqn 4 from eqn 5

10a + 10b = 6050 eqn 5

          -

10a + 4b = 5420 eqn 4

= 6b = 630

b = 105

Students who bought the ticket are 105

Substitute for b in eqn 3

a + 105 = 605

a = 500

Adults who bought the ticket are 500

The bases on a baseball diamond are 90 feet apart. how far is it from home plate to second base?
Karolina [17]
See diagram

so we got a right triangle

so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²


so the legs are 90 and 90
hytponuse is distance from home to 2nd

so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c
aprox
127.279ft
about 127ft

What would BI be? I don’t get it
dedylja [7]

Answer:

34

Step-by-step explanation:

Of I is the incenter then : AI, BI, and CI would be equal

if lengths are equal we can make an equation to solve the length of BI

AI = BI ➡ 3x+7 = 5x-11 ➡ 2x = 18 ➡ x = 9

replace x with 9

5x-11 ➡ 5×9-11 = 34
