What's is √13×√52 = ?
Answer:
[tex]26[/tex]
Step-by-step explanation:
We have:
[tex]\sqrt{13}\times\sqrt{52}[/tex]
Notice that 52 is the product of 13 and 4. So:
[tex]=\sqrt{13}\times \sqrt{13\times 4}[/tex]
We can separate the second one:
[tex]=\sqrt{13}\times\sqrt{13}\times\sqrt{4}[/tex]
We can combine the first two:
[tex]=\sqrt{13\times13}\times\sqrt4[/tex]
We can write [tex]13\times13[/tex] as [tex]13^2[/tex]. So:
[tex]=\sqrt{13^2} \times \sqrt4[/tex]
The square root and the square will cancel. The square root of 4 is 2. So:
[tex]=13\times2[/tex]
Multiply:
[tex]=26[/tex]
Therefore:
[tex]\sqrt{13}\times\sqrt{52}=26[/tex]

Can anyone tell me if The last one is right?
Answer:
See below.
Step-by-step explanation:
All linear dimensions are in ft, and all areas are in ft².
Pyramid:
Lateral area: 4 × 6 × 5 / 2 = 60
Base area: 6 × 6 = 36
Total surface area: 96
Hidden surface area (the square base): 36
Actual surface area in the composite solid: 60
Square prism:
Lateral area: 4 × 20 × 6 = 480
Base area: 2 × 6 × 6 = 72
Total surface area: 552
Hidden surface area (both square bases): 72
Actual surface area in the composite solid: 480
Cube:
Total surface area: 6 × 6 × 6 = 216
Hidden surface area (one base): 36
Actual surface area in the composite solid: 180
The surface areas above are for each of the above solids if each were free standing and unattached to other solids.
The way the three components are above, you must deduct some areas of bases (as shown above in the actual surface areas) since they are internal.
Pyramid actual visible area: 60
Square prism actual visible area: 480
Cube: 180
Total surface area: 720

how much do you need to subtract from 77/10 to make 7
Answer: 7/10 or 0.7
Step-by-step explanation: 77/10 in decimal form is 7.7. To make 7, you would need to subtract that .7 which would translate to 70/10 after it's subtracted, which is 7.
Answer:
7
Step-by-step explanation:
you need to subtract 7 because 77/10 is 7.7
77-7 is 70. 70/10 is 7
Write a function t(I) that determines the number of
toothpicks in any given level of the pyramid.
Using the table, we will see that the function is:
t(l) = 3*l
How to write the function?
Here we only have a table to work with, so we need to use that.
In the table, we can see the pairs:
t(1) = 3t(2) = 6t(3) = 9t(4) = 12So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.
From that we can conclude that the function will be:
t(l) = 3*l

This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the
base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the
base?
A cubic inches
(b) The crystal is actually half an inch thick on each of the sides and on the bottom.
Approximately how much space is contained within the vase?
A cubic inches
The volume of the vase when the crystal itself has no thickness will be 240 inches³.
How to calculate the volume?The volume of the vase when the crystal itself has no thickness will be calculated thus:
V = Bh
V = (4in × 5in) × 12
V = 240 inches³
When the crystal is half an inch thick on each of the sides and on the bottom, the volume will be:
= 1/2 × 240 inches ³

3. Boynton Beach recreation center has collected a total of 510 donated tickets for free ice
cones. Beginning on the second day of summer vacation, the recreation center randomly
selects 9 children to each receive one of the free ice cream tickets. Assuming the
recreation center continues this pattern of giving away tickets to 9 children each day,
which explicit formula shows the
number of ice cone tickets remaining at the end of the
day, after n number of days?
a.=510-9n
B.=510+9(n-1)
C.510-9(n-1)
D.9(n-1)-510
Answer:
Hence, in this case, it is concluded that the correct answer is "N = 618 - n x 7"
Step-by-step explanation:
Considering the situation described above, the explicit formula that shows the number of ice cream tickets remaining at the end of the day, after n number of days is "N = 618 - n x 7."
This is based on the idea that each day of the ice cream ticket is defined as 7 tickets taken.
Thus the ticket listing for each day is described as
Day 1. 618 - 7 OR 618 - 1 × 7;
Day 2. 618 - 14 OR. 618 - 2 × 7;
Day 3. 618 - 21 OR 618 - 3 × 7;
Therefore, from this illustration above, the formula needed is: "N = 618 - n x 7."
3-) Martha O'Brien made a deposit to her checking account at an ATM and received
$75 in cash. The checks deposited totaled $50 less than twice the currency amount,
and the total deposit was $25 more than the check amount. Determine the amounts
Martha deposited in checks and in currency as well as the total deposit.
Answer:
The amount Martha deposited in checks is $150
The amount Martha deposited in cash is $100
The total deposit is $175
Step-by-step explanation:
Since Total deposit (T) = currency (C) + coins + check (Ck) - cash received (Csh)
T = C + Ck - Csh. (1)
Given that cash received (Csh) = $75,coins = 0 and the checks deposited totaled $50 less than twice the currency amount. So,
Ck = 2C - $50 (2)
Also, total deposit was $25 more than the check amount. So,
T = Ck + $25 (3)
Substituting equation (2) into (1), we have
T = C + Ck - Csh
T = C + 2C - $50 - Csh
T = 3C - $50 - $75
T = 3C - $125 (4)
Substituting equation (2) into (3), we have
T = Ck + $25
T = 2C - $50 + $25
T = 2C - $25 (5)
Equating equations (4) and (5), we have
3C - $125 = 2C - $25
Collecting like terms, we have
3C - 2C = $125 - $25
C = $100
Substituting C into (2), we have
Ck = 2C - $50
Ck = 2($100) - $50
Ck = $200 - $50
Ck = $150
We now compute T
T = C + Ck - Csh.
T = $100 + $150 - $75.
T = $250 - $75
T = $175
So, the amount Martha deposited in checks is $150
The amount Martha deposited in cash is $100
The total deposit is $175

Which of the following is NOT true about the following equation? y=−3
A) It is the equation of a horizontal line.
B) Its slope is zero.
C) It is perpendicular to the equation y=13x+2.
D) The line does not cross the x-axis.
Answer:
The statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2 ⇒ C
Step-by-step explanation:
Let us revise the facts of the horizontal line:
The line is horizontal if all points on it have the same y-coordinatesThe horizontal line is parallel to the x-axisThe slope of the horizontal line is zeroThe equation of the horizontal line is y = b, where b is the y-coordinate of all points on the lineThe y-intercept of the horizontal line is (0, b)∵ The equation of the line is y = -3
→ Which means the value of y = -3 at any value of x
∴ The line is horizontal
∴ Its slope = 0
∵ The horizontal line is parallel to the x-axis
∴ The line does not intersect the x-axis
∴ The true statements are:
It is the equation of a horizontal lineIts slope is zeroThe line does not cross the x-axisThe statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2

Renee, Susan, and Martha will share the cost to rent a vacation house for a week. • Renee will pay 40% of the cost. • Susan will pay 0.35 of the cost. • Martha will pay the remainder of the cost. Martha thinks that she will pay 13 of the cost. Is Martha correct?
Answer:
Martha is wrong.
Step-by-step explanation:
Let the cost of the house is C.
Payment by Ranee = 40% of the cost
=40% of C
=[tex]\frac{40}{100}\times C[/tex]
=0.40 C
Payment by Susan = 0.35 of the cost
=0.35 C
Combined payment by Ranee and Susan = 0.40C + 0.35C=0.75C
The remaining payment will be done by Martha.
So, the remaining payment = C- 0.75C=0.25 C
Hence, Martha will have to pay 0.25 of the cost or 25% of the cost.
So, Martha is wrong.
