1).[tex] \frac{x}{8} = \frac{9}{24} [/tex]
Cross multiply
We have
24x = 72
Divide both sides by 24
That's
[tex] \frac{24x}{24} = \frac{72}{24} [/tex]
We have the answer as
x = 32).3x² + 2x - 10
when x = - 1
Substitute the value of x into the expression
That's
3(-1)² + 2(-1) - 10
= 3 - 2 - 10
We have the answer as
- 9When x = 0
That's
3(0) + 2(0) - 10
= - 10When x = 1
That's
3(1)² + 2(1) - 10
= 3 + 2 - 10
= 5 - 10
= - 53).[tex] \sqrt{( - 9)} [/tex]
First of all apply the radical rule
That's
[tex] \sqrt{ - a} = \sqrt{ - 1} \times \sqrt{a} [/tex]
So we have
[tex] \sqrt{ - 9} = \sqrt{ - 1} \times \sqrt{9} [/tex]
Using the imaginary rule
That's
[tex] \sqrt{ - 1} = i[/tex]
We have
[tex] \sqrt{9} \times i[/tex]
We have the final answer as

when x = 0
We have

when x = 1
[tex] \frac{1}{1} = 1[/tex]
when x = 2
We have
[tex] \frac{1}{2} [/tex]

given the indicated terms of an arithmetic sequence a3=1, a33=22 find the first term
Answers
Answer:
The first term is a = 0.4.
Step-by-step explanation:
We are given the indicated terms of an arithmetic sequence; [tex]a_3[/tex] = 1, [tex]a_3_3[/tex] = 22.
As we know that the nth term of the A.P. is given by;
[tex]a_n=a+(n-1)d[/tex]
where, a = first term and d = common difference
Now, the third term of AP is given as 1, this means;
[tex]a_3=a+(3-1)d[/tex]
[tex]a+2d=1[/tex]
a = 1 - 2d --------------- [equation 1}
Also, the 33rd term of AP is given as 22, this means;
[tex]a_3_3=a+(33-1)d[/tex]
[tex]a+32d=22[/tex]
[tex]1-2d+32d=22[/tex] {using equation 1}
[tex]30d=21[/tex]
[tex]d=\frac{21}{30}[/tex]
d = 0.7
Putting the value of d in equation 1 we get;
[tex]a=1-(2 \times 0.7)[/tex]
a = 1 - 1.4 = -0.4
Hence, the first term of an AP is -0.4.

A pizza restaurant offers 6 toppings to choose from for their pizzas, and no toppings is considered a plain cheese pizza. How many different pizza topping combinations are possible if the maximum number of allowed toppings is 3 and toppings can't repeat
Answers
Answer: 120
Step-by-step explanation:
Given : Total toppings = 6
Number of toppings needs to be selected = 3
Also if repetition of toppings is not allowed , then the number of combinations are possible = 6 x 5 x 4 [First we choose 1 out of 6 , then 1 out of remaining 5 and then 1 out of 4,then multiplying the choices for 3 toppings]
= 120
Hence, the number of different pizza topping combinations are possible if the maximum number of allowed toppings is 3 is 120 .

The three incoming currents at a
node in an electrical circuit
measure 0.38 amps, 0.75 amps,
and 0.29 amps. Two of the three
outgoing currents measure 0.48
amps and 0.6 amps. Find the
measure of the third outgoing
Current
PLS HELP
Answers
Answer:
Measure of the third outgoing current will be 0.34 ampere.
Step-by-step explanation:
Kirchhoff's Current Law states that total current entering a circuit's junction is exactly equal to the total current leaving the same junction.
By this rule,
Sum of input three currents = Sum of three outgoing currents
0.38 + 0.75 + 0.29 = 0.48 + 0.6 + i
1.42 = 1.08 + i
i = 0.34
Therefore, measure of the third outgoing current will be 0.34 ampere.

Jason with 120 and is going 10 pounds each month Gerardo weighs 150 pounds and is having 4 pounds each month . Write an equation that shows how many months , m , it will take for Jason weigh the same as Gerardo
Answers
Answer:
5 months
Step-by-step explanation:
Jason's original weight = 120 pounds
Let the no. of months be m
If he gains 10 pounds in each moth , then his weight in m months will be = 10m
His total weight will be= 120+10m -----(1)
Gerardo's original weight = 150 pounds
If he gains 4 pounds in each month , then his weight in m months will me =4m
His total weight will be = 150+4m-----(2)
Equating (1) ans(2)
120+10m=150+4m
=>10m-4m=150-120
=>6m=30
=>m=[tex]\frac{30}{6}[/tex]

Three consecutive numbers are such that when they are taken in increasing order and multiplied by 2,3and 4 respectively, they add up to 74. Find these numbers.
Answers
Answer:
7 , 8 , 9
Step-by-step explanation:
Assume three consecutive number are,
x , (x+1) , (x+2)
Multiplied by 2 ,3 and 4 respectively
2x , 3(x + 1) , 4(x + 2)
Sum of all = 74
So,
2x + 3(x + 1) + 4(x + 2) = 74
2x + 3x + 3 + 4x + 8 = 74
9x + 11 = 74
9x = 63
x = 7

Option (C)
Step-by-step explanation:
x and y are two rational numbers.
Two inequalities which define these numbers are,
x + y < 5 ------(1)
3 < x < 5 -------(2)
In this question we will substitute the values of y given in the options in the inequality (1) to get the value of x. If the value of x satisfies the inequality (2), it will be the answer.
Option (A). y = [tex]\frac{8}{3}[/tex]
From inequality (1),
[tex]x+\frac{8}{3}<5[/tex]
[tex]x<5-\frac{8}{3}[/tex]
x < [tex]\frac{7}{3}[/tex]
x < 2.33
But 3 < x < 5, therefore, y = [tex]\frac{8}{3}[/tex] is not the answer.
Option (B). y = 2
x + 2 < 5
x < 3
But x is greater than 3. Therefore, Option (B) will not be the answer.
Option (C). y = 0
x + 0 < 5
x < 5
Inequality (2) states the same thing.
Therefore, Option (C) will be the answer.
Option (D). y = 3
x + 3 < 5
x < 5 - 3
x < 2
But x > 3, therefore, Option (D) will not be the answer.
Answer:
C is correct because if x is less than 5 and greater than 3 than is would most likely be 4 and 4 plus 0 equals 4 the problem says x plus y should be less than 5 and 4 plus 0 is less than 5
