Answer:
4. \( 36 \sqrt{2} \)
Step-by-step explanation:
\( 6\sqrt{50} + 6 \sqrt{2} \)
= \( 6 \sqrt{25 \times 2} + 6 \sqrt{2} \)
= \( 6 \times 5\sqrt{2} + 6 \sqrt{2} \)
= \( 30 \sqrt{2} + 6 \sqrt{2} \)
= \( \bold{36 \sqrt{2}} \)

The area of a garden is 12.9 square feet. Each square foot of the garden needs to have 2.6 pounds of soil.
How many pounds of soil are needed for the garden?
on ixl and these questions keep coming up.
Answer:
15.9
Step-by-step explanation:
Since the volume of a cube is equal to length*width*height, and we know that in this case length, width, and height are all equal, since it is a cube, all you need to do is create an equation like this:
4019.679 = x^3
x is the side length.
15.9*15.9*15.9, 15.9^3.
Select all of the prime numbers from the list that can divide the number 14 exactly.

Jackson works as a veterinary technician and earns $12.20 per hour. Jackson normally works 40 hours a week. And a normal week, what is his total pay before taxes and other deductions
Answer:
p = 12.20h
30.5 hours
Step-by-step explanation:
Jackson works as a veterinary technician and earns per hour = $12.2
He works in a normal week = 40 hours
Let hours = h and weekly pay = p
p = 12.20h
p = $12.20 × 40
= $488.00
Last week Jackson was ill and missed some work.
His total pay before deduction was $372.10
To find the hours he work the equation will be p = 12.20h
372.10 = 12.20h
372.10/12.20 = h
h= 30.5

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

X + 7 = 23 middle school work
Answer:
X = 16
Step-by-step explanation:
23 - 7 = 16
Answer: 16
Step-by-step explanation:
23 - 7 = X
To find X we do the inverse of addition which is subtraction. The 7 cancels out and the 23 becomes a 16. We can even check our answer. 16 + 7 = 23
A hamster's heart beats about 2,250 beats every 5 minutes. A dog's heart beats about 450 times every 5 minutes.
How many more beats does a hamster's heart beat in 10 minutes than a dog's heart?
Answer:
4,100
Step-by-step explanation:
add 2,250+2,250=5,000
then add 450+450=900
5000-900+4100
therefore the hamster's heart beats 4,100 more times than a dog in 10 min

Julius went fishing on Saturday morning. He took a cooler to store the fish that he caught. The cooler could hold no more than 6 large fish. Write an inequality that represents how many fish the cooler could hold.
A: 6 < f
B: 6 ≤ f
C: 6 > f
D: 6 ≥ f
Answer:
Step-by-step explanation:
The answer is 6 ≤ f since the question says no more than 6 which means it can contain 6 or fewer large fishes
Write the equation of the line in either point-slope form or slope-intercept form.
Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).
Use the drop-down menus to select the appropriate values in the equation.
y =----x+----
Answer:
y = -3x - .25 or y = -3x + -.25
Step-by-step explanation:
y = slope (x) + y-intercept
-4 = -3(1.25)+b
-4 = -3 .75 + -.25
-4 = -4
Quinn has 6 bottles of water that each weigh \large \frac{3}{5} pound. What is the total weight of the water bottles?_
Quinn has 6 bottles of water that each weigh \large \frac{3}{5} pound. What is the total weight of the water bottles?
Answer:
3.6 pounds
Step-by-step explanation:
If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5
ratio method :
1:3/5
6:x
since the ratios are direct we can cross multiply
18/5 = 1x
so the 6 bottles weigh 18/5 pounds or 3.6 pounds

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Step-by-step explanation:
all interior angles should add up to 180 so:
38+81-180=61
Answer:
Step-by-step explanation:
Ok, so there is a property known as angle sum property.
Basically, it states that in a triangle, the sum of all the angles is 180° no matter what the triangle is.
Use that here.
81° + 38° + x° = 180°
119° + x° = 180°
x° = 61°
