I WILL GIVE BRAINLY What will be the surface area of the figure given below (in square feet)? Choose the correct option.
Answers
Answer:
145
Step-by-step explanation:
Each triangular side is 30ft
bottom is a 5*5 so it 25ft
30*4(#of sides)=120
120+25(bottom)=145
Answer:
I will give you the easy explanation here, go down there though to get a more complexed explanation and answer. Seeing it is a triangle, you can not multiply the 12 by 5. You have to multiply it by 2.5 because it dips in (because it's a triangle). Now you multiply the 5x5 to get 25. Now we have 25 for the base and 30 for each side. 30x4 to represent each side and add 25 for the base to get 145 as the final answer.
Step-by-step explanation:
Ok, they made this really easy with the 5's. You multiply the 5 by the 5 to get 25 in which the 12 there is about half of that, that made things really easy. Since the 12 goes to the middle that means that we can take what is from the middle to the side removing the half there getting you -2. Therefore, 12-2=10. Meaning the center is 10.

a baby goraffe is about 6 1/2 feet tall at birth and grows about 1/2 foot per month for its first year. The function h=1/2m+61/2 represents the total height h of a baby giraffe for any number of months m within ita firat year. How much taller is the giraffe at the end of the month 11 than at the end of month 2
Answers
Answer: 4 and 1/2 ft (or 4.5 ft) taller.
Step-by-step explanation:
The function h(m) = (1/2)*m + (6 + 1/2) represents the height (on feet) of the giraffe as a function of the number of months, m.
We want to find the difference in the height between month 11 and month 2, then we need to find:
difference = h(11) - h(2)
We can directly calculate this:
difference = [ (1/2)*11 + (6 + 1/2)] - [(1/2)*2 + (6 + 1/2)]
difference = (1/2)*11 - (1/2)*2 = (1/2)*(11 - 2) = (1/2)*(9) = 9/2
And we can write 9 = 9 + 1, then:
difference = 9/2 = (8 + 1)/2 = 8/2 + 1/2 = 4 + 1/2
And this is in feet, then the girrafe is (4 and 1/2) ft taller on month 11 than on month 2.

The population of a small town is growing at a rate of 5% per year. If the population right now is 22 000, What will the population be 10 years from now?
Answers
Answer:
35,836
Step-by-step explanation:
I had this question before and I believe this is correct.
Answer:
the population 35,836 in 10 years.
Step-by-step explanation:
The numbers representing the population in consecutive years create a geometrical sequence with:
a1 = 22,000
and
q = 1 + 0.5 = 1.05
We are asked to find the population after
10 years. This number is the eleventh term in the sequence, so we are looking for:
a11 = a1 ⋅ q^10 = 22, 000 ⋅ (1.05)^10
After substitution of given data we have:
a11 ≈ 35, 836
*Answer:* "After 10 years the population will be 35, 836."
The number of days, d, that it will take to build a house is given by
d= 720 divided by n
where n is the number of workers used each day.
Ali's company will take 40 days to build the house.
Hayley's company will take 30 days to build the house.
Hayley's company will have to use more workers each day than Ali's company.
How many more?
Answers
Answer:
6 more workers
Step-by-step explanation:
The relationship between days (d) and number of workers (n) is given by the equation;
d = 720 / n
Ali's company will take 40 days to build the house.
n = 720 / d
n = 720 / 40 = 18 workers
Hayley's company will take 30 days to build the house.
n = 720 / d
n = 720 / 30 = 24 workers
Hayley's company will have to use more workers each day than Ali's company.
How many more?
24 - 18 = 6 more workers

Answer:
101
Step-by-step explanation:
(There is a shorter way to solve this, is in the other answer omg sorry)
First we have to find the last angle of the smallest triangle.
The addition of all angles in a triangle is always 180º so that means:
39 + 25 + y = 180
y = 180 - 64
y = 116
Now that we know the value of that angle we can find the other angle (not x) and with it we can get the answer.
Because flat angles are 180º too
Then:
116 + z = 180
z = 180 - 116 = 64
Finally now we calculate the addition of all angles again to find x:
x + 15 + 64 = 180
x = 180 - 79
x = 101

Mai, Clare, and Tyler are hiking from a parking lot to the summit of a mountain. They pass a sign that gives distances. 3 • Parking lot: 3/4 mile • Summit: 1 1/2 miles Mai says: "We are one third of the way there." Clare says: "We have to go twice as far as we have already gone." Tyler says: “The total hike is three times as long as what we have already gone." a) Can they all be correct?
Answers
Answer:
Yes they can
Step-by-step explanation:
.
Tyler's statements are consistent with the given distances.
To determine if Mai, Clare, and Tyler can all be correct, we need to evaluate the statements they made in relation to the given distances.
Statement 1: Mai says, "We are one third of the way there."
The distance from the parking lot to the summit is 1 1/2 miles. If they are one third of the way there, the distance they have already traveled would be 1/3 * 1 1/2 miles = 1/3 * 3/2 miles = 1/2 mile. However, the given distance from the parking lot is 3/4 mile, which is greater than 1/2 mile. Therefore, Mai's statement cannot be correct.
Statement 2: Clare says, "We have to go twice as far as we have already gone."
If they have already gone a distance of x, then according to Clare's statement, they have to go a distance of 2x. This statement does not contradict the given distances, so it could be true.
Statement 3: Tyler says, "The total hike is three times as long as what we have already gone."
If they have already gone a distance of x, then according to Tyler's statement, the total hike would be 3x. This statement also does not contradict the given distances, so it could be true.
Based on the analysis, only Mai's statement cannot be correct. Clare and Tyler's statements are consistent with the given distances.

The best describes the relationship between x and y will be;
⇒ Strong negative correlation.
What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The results of a linear regression are shown below,
⇒ y = ax + b
⇒ a = -1.15785
⇒ b = 139.3171772
⇒ r = -0.896557832
⇒ r₂ = 0.8038159461
Now,
With the value of r we have both the information about the sign of the relationship and the strength of this relationship.
⇒ As the value of r is negative, we can conclude that the correlation between x and y is negative.
Also, as the absolute value of r is close to 1, we can conclude that this relationship is strong.
And, The strength can also be seen in the value of r2, which is also close to 1, but this value does not give information about the sign.
Thus, The value of the slope a, being negative, can also tell us that the relation between x and y is a negative correlation.

This question is worth 2 points! Allison makes and sells beaded necklaces. She charges a flat fee of $5 per necklace, and $1.50 per bead that she adds. If Jennifer, who wants to purchase a necklace, has $34 to spend, how many beads can she add to her necklace? Explain the process you used to solve, and tell what your answer is.
Answers
Answer:
19 beads
Step-by-step explanation:
If Jennifer has 34$ she automatically loses 5$ because that's the fee for the necklace. So, you subtract 34 from 5 and you get 29. After that you divide 29 by 1.50 and you get 19.333333. But, since you can't get 1/3 of a bead Jennifer can only buy 19 beads.
