Answer:
Eda's weight is 34 pounds.
Step-by-step explanation:
Given that,
The mean (average) weight of three dogs is 38 pounds.
Weight of Shaggy = 46 pounds
Let weight of Eda and Bruno is x.
The formula of average is given by :
Average = sum of observations/no. of observations
[tex]38=\dfrac{x+x+46}{3}\\\\114=2x+46\\\\114-46=2x\\\\2x=68\\\\x=34[/tex]
Hence, Eda's weight is 34 pounds.

given the functions f(x)=2x-4 and g(x)= x+2 find the value of x
Show your work
x = 0 and x = 4
To find intersection equate them.
x² - 2x - 4 = 2x - 4
subtract 2x - 4 from both sides
x² - 4x = 0 → (take out common factor x)
x(x - 4 ) = 0 ⇒ x = 0 , x = 4

Express in simplest radical form square root 96/2
Answer:
√[(2*2)*(4*6)]
= 4 √6
Step-by-step explanation:
√96.
Sometimes it is better to ‘simplify’ by getting a coefficient multiplied by a smaller number within the radical. Other times, you’re really not simplifying, but making it more complicated. This is probably one of those times where leaving it as √96 is better.
If you had something like √196, you would want to change that form since it turns out that 196 is a perfect square.
Regardless, I’m assuming this is a problem for a class and your teacher/text book wants you to do the following……
You could start by factoring it in small steps within the radical sign.
If you find factors that are perfect squares, you can take them out of the radical.
You can find large factors if you want, but you can also start with small factors.
Probably the easiest number to factor out is 2 since 96 is an even number.
96/2 = 48.
square root 96 radical form
48 is also an even number, so you can factor another 2.
Now you have √[(2*2)*24]
If you can factor out larger numbers, it can save you a little time.
So from here let’s factor out a 4.
√[(2*2)*(4*6)]
= 4 √6

Step-by-step explanation:
Sally is 13 years old.
Tammy is 12 years old.
Danny is 10 years old.
Sally, Tammy and Danny share £28 in the ratio of their ages.
Tammy gives a third of her share to her mother.
How much should Tammy now have?
Answer:
$6.40
Step-by-step explanation:
13 + 12 + 10 = 35
28 / 35 = 0.8
0.8 * 12 = 9.6
9.6 * 2/3 = 6.4
The money Tammy has now if Sally is 13 years old. Tammy is 12 years old. Danny is 10 years old. Sally, Tammy, and Danny share £28 in the ratio of their ages. Tammy gives a third of her share to her mother is $4.57.
What is ratio?It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3.
Given:
The age of Sally = 13 years,
The age of Tammy = 12 years,
The age of Danny = 10 years,
Then according to the question
13x + 12x + 10x = 28
35x = 28
x = 4 / 7
One-third of Tammy's money = 12 × 4 / 7 ×1 / 3 = 2.285
Money left = 48 / 7 - 2.285 = 4.57
Therefore, the money Tammy has now, if Sally is 13 years old. Tammy is 12 years old. Danny is 10 years old. Sally, Tammy, and Danny share £28 in the ratio of their ages. Tammy gives a third of her share to her mother is $4.57.

Step-by-step explanation:
On skates, Ian can travel `\frac{3}{4}`of a mile in 5 minutes. On his bike, he can travel `3\ \frac{1}{2}`miles in 12 minutes. How fast, in miles per hour, can Ian travel on skates AND on his bike?
Answer:
a) 9 miles/hour
b) 17.5 miles/hour
Step-by-step explanation:
The formula for speed = Distance (Miles) / Time(hours)
a) he can travel 3/4 of a mile in 5 minutes.
= 3/4 miles = 5 minutes
We convert 5 minutes to hour
= 60 minutes = 1 hour
5 minutes = x
Cross Multiply
60x = 5
x = 5/60
x = 1/12 hour
Hence, his skate speed =
3/4miles /1/12 hour
= 3/4 ÷ 1/12
= 3/4 × 12/1
= 9 miles/hour
b) On his bike, he can travel 3 1/2 miles in 12 minutes.
= 3 1/2 = 12 minutes
= 7/2 miles = 12 minutes
We convert 12 minutes to hour
= 60 minutes = 1 hour
12 minutes = x
Cross Multiply
60x = 12
x = 12/60
x = 1/5 hour
Hence, his skate speed =
7/2 miles /1/5 hour
= 7/2 ÷ 1/5
= 7/2 × 5
= 35/2 miles/hour
= 17.5 miles/hour
The sum of three consecutive even numbers is 552. What is the 1st number?
Answer:
Let 2n = the first of three consecutive even numbers, where n is an integer.
Let 2n + 2 = the second of three consecutive even numbers, and
Let 2n + 4 = the third of three consecutive even numbers.
We're given that "sum of three consecutive even numbers is 552." We can translate this English sentence mathematically into the following equation to be solved for n:
2n + (2n + 2) + (2n + 4) = 552
Removing the parentheses, we have:
2n + 2n + 2 + 2n + 4 = 552
Now, by the Commutative Law of Addition, i.e., a + b = b + a, we have on the left side of the equation:
2n + 2n + 2n + 2 + 4 = 552
Now, collecting like-terms on the left, we get:
6n + 6 = 552
To solve for the variable n, We now begin isolating n on the left side by subtracting 6 from both sides as follows:
6n + 6 - 6 = 552 - 6
6n + 0 = 546
6n = 546
Now, divide both sides by 6 to finally solve for n:
(6n)/6 = 546/6
(6/6)n = 546/6
(1)n = 91
n = 91
Therefore, the first of three consecutive even numbers, 2n, is:
2n = 2(91)
= 182
The second of three consecutive even numbers is:
2n + 2 = 2(91) + 2
= 182 + 2
= 184
The third of three consecutive even numbers is:
2n + 4 = 2(91) + 4
= 182 + 4
= 186
CHECK:
2n + (2n + 2) + (2n + 4) = 552
182 + 184 + 186 = 552
552 = 552
Therefore, the desired and first of three consecutive even numbers is indeed 2n = 182.

After a while, Jackie gets tired and decided to rent a bike to get to the south end of the trail. She cycles at an average speed of 15 mph. If Jackie gets to the south end of the trail in two hours, how far did she walk? (Round to two decimal places)

Pablo folds a straw into a triangle with side lengths of 4x2−3 inches, 4x2−2 inches, and 4x2−1 inches. Which expression can be used to find the perimeter of the triangle, and what is the perimeter when x = 1.5?
12x2 −6; 21 inches
12x2; 27 inches
12x2 −6; 30 inches
12x2; 36 inches
Answer:
12x² - 6; 21 inches ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The side lengths of a triangle are 4x² - 3 in., 4x² - 2 in., 4x² - 1 in.
∴ S1 = 4x² - 3 inches
∴ S2 = 4x² - 2 inches
∴ S3 = 4x² - 1 inches
→ The perimeter of the triangle is the sum of the lengths of its 3 sides
∵ P = S1 + S2 + S3
∴ P = 4x² - 3 + 4x² - 2 + 4x² - 1
→ Add the like terms
∵ P = (4x² + 4x² + 4x²) + (-3 + -2 + -1)
∴ P = 12x² + -6
→ Remember (+)(-) = (-)
∴ P = 12x² - 6
∴ The expression of the perimeter of the Δ is 12x² - 6
∵ x = 1.5
→ Substitute x in the perimeter expression by 1.5
∵ P = 12(1.5)² - 6
∴ P = 12(2.25) - 6
∴ P = 27 - 6
∴ P = 21 inches
∴ The perimeter of the triangle is 21 inches
The expression can be used to find the perimeter of the triangle is 12x² - 6 and its perimeter is 21 inches when x = 1.5

For which pairs of function is (g*f)(a)=|a|-2
Answer:
Option 3
Step-by-step explanation:
Option 1
f(a) = a² - 4
g(a) = √a
(gof)(a) = [tex]\sqrt{a^{2}-4}[/tex]
Option 2
f(a) = [tex]\frac{1}{2}a-1[/tex]
g(a) = 2a - 2
(gof)(a) = [tex]2[\frac{1}{2}a-1]-2[/tex]
= (a - 2) - 2
= a - 4
Option 3
f(a) = 5 + a²
g(a) = [tex]\sqrt{(a-5)}-2[/tex]
(gof)(a) = [tex]\sqrt{(a^2+5-5)}-2[/tex]
= |a| -2
Option 4
f(a) = 3 - 3a
g(a) = 4a - 5
(gof)(a) = 4(3 - 3a) - 5
= 12 - 12a - 5
= 7 - 12a
Therefore, Option 3 is the answer.
