Answer:

Step-by-step explanation:

We are given the expression:

2/5g+ 3h - 6

We know that g=10 and h=6. Therefore, we can substitute 10 and 6 into the expression and solve according to PEMDAS( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

2/5(10)+3(6)-6

First, multiply 2/5 and 10

4+ 3(6)-6

Next, multiply 3 and 6

4+18-6

Next, add 4 and 18

22-6

Finally, subtract 6 from 22

2/5g + 3h - 6 when g=10 and h= 6 is 16.

Answer:

Step-by-step explanation:

Well first we need to plug in 10 for g and 6 for h.

2/5(10) + 3(6) - 6

4 + 18 - 6

22 - 6

<em>the answer is 16.</em>

A school offers band and chorus classes. The table shows the percents of the 1200 students in the school who are enrolled in ban

julsineya [31]

Using Venn probabilities, it is found that 240 students are enrolled in both classes.

<h3>Venn probabilities:</h3>

The events are:

Event A: A student is enrolled in band.

Event B: A student is enrolled in chorus.

The supposed percentages, which also represents the probabilities involving a single student, are:

50% of the students involved in the band, hence $P(A) = 0.5$ .

40% of the students involved in the chorus, hence $P(B) = 0.4$ .

30% involved in neither, hence $1 - P(A \cup B) = 0.3 \rightarrow P(A \cup B) = 0.7$ .

The percentage involved in both is:

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

Hence:

$P(A \cap B) = 0.5 + 0.4 - 0.7 = 0.2$

Then, out of 1200 students:

$0.2(1200) = 240$

240 students are enrolled in both classes.

How to solve the problem <br> Step by step

Butoxors [25]

Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

= 1 / 8 + ( - 5 / 12 ) - 3 / 8

= 1 / 8 - 5 / 12 - 3 / 8

= ( 3 - 10 - 9 ) / 24

= - 16 / 24

= - 2 / 3

Hope this helps! <3

Jason spent $46.42 on dinner at hello tokyo. he also spent $21.05 on gas for the car. if his bank account had $60.00, what is hi

AleksandrR [38]

It would be: $60.00 - ($46.42+$21.05)

$60.00 - $67.47 = -$7.47

Suppose that the functions u and w are defined as follows.

leonid [27]

Step-by-step explanation:

(a○b)(x) is the same as a(b(x)).

it is really that simple.

first you calculate the result of the inner function, and then that result is the input for the outer function.

that's it.

so,

(w○u)(2) = w(u(2))

u(2) = -2 -1 = -3

w(-3) = 2×(-3)² + 1 = 2×9 + 1 = 19

so, 19 is the first answer.

(u○w)(2) = u(w(2))

w(2) = 2×2² + 1 = 2×4 + 1 = 9

u(9) = -9 - 1 = -10

so, -10 is the second answer.
