simplify the following expression 4√72

Answer:357.96in

Step-by-step explanation:

1. Surface area of a cylindar is A= 2πr(r+h)

2. A= 2·π·3 (3+16)

Second question

Answer: 296in

Answer:

406.08

Step-by-step explanation:

First FInd the area of the rectangle : which is short side * long side

-> 15*12=180m

Then find the area of the half circle, the formula of the area of a circle is [tex]\pi r^2[/tex]

here it's half a circle so it's [tex]\frac{\pi r^2}{2}[/tex] where r is 12

-> [tex]3.14\cdot \frac{\left(12\right)^2}{2}=226.08 m[/tex]

Finally just add the area of the rectangle with the area of the half circle

-> [tex]180+226.08=406.08 m[/tex]

[tex]\frac{2^x \times 3^y}{2^4 \times 3^2} = 6\\\\\frac{2^x \times 3^y}{2^4 \times 3^2} = 2\times3\\\\\frac{2^x \times 3^y}{2^4 \times 3^2} = 2^1\times3^1\\\\2^x \times 3^y = (2^4 \times 3^2)(2^1\times 3^1)\\\\2^x \times 3^y = (2^4\times2^1) (3^2\times 3^1)\\\\2^x \times 3^y = 2^{4+1} \times 3^{2+1}\\\\2^x \times 3^y = 2^{5} \times 3^{3}\\\\[/tex]

The 2^x matches with 2^5, showing that x = 5.

3^y matches with 3^3 to get y = 3

Therefore, x+y = 5+3 = 8

Using proportions, it is found that the cost of each banana is of $0.59, and Juan is the student who wrote and solved the equation correctly.

A proportion is a fraction of a total amount.

In this problem, the cost of 4 bananas is $2.36, hence the cost of each banana is given by:

C = $2.36/4 = $0.59.

Which means that Juan is correct.

Step-by-step explanation:

The predicted strength is an illustration of a linear regression

The predicted strength of a weld with a diameter of 51 is -503.2

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988*Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988*51

Evaluate the sum

Strength = -503.1604

Approximate

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2

The predicted strength is an illustration of linear regression.

The predicted strength of a weld with a diameter of 51 is -503.2.

Linear regression strives to show the relationship between two variables by applying a linear equation to observed data.

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988 × Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988 × 51

Strength = -941.6992 + 438.5898

Strength = -503.1604

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2.

Answer:

Rs. 480

Step-by-step explanation:

Per month interest amount = 2000 x 0.02 = Rs.40

One total interest cost =Rs. 40 x 12 ( 12months i. e. 1 year)

= Rs. 480

Answer:

52.

Step-by-step explanation:

shaded = (3²) + (2²)

shaded = 9 + 4

shaded = 13

Unshaded = (3 x 2) + (2 x 3)

Unshaded = 6 + 6

Unshaded = 12

All = 12 + 13

All = 25

100 / 25 = 4

4 x 13 = 26 x 2

26 x 2 = 52.

So if i'm reading it right, it says the total depreciation will be 13% & 14% after the 5 years. If i'm misunderstanding, let me know and i'll fix my answer because the process will be a bit different

Depreciation means a decrease in something over time. You can think of it like a "__% off" sale if that helps

For the first option, we need to find 13% of 18,000. "Of" always means multiply, so 13%*18,000=2,340

Since we're decreasing, subtract 2,340 from the original cost

18,000-2,340=$15,660

Same process for the second option

14%*22,000=3,080

22,000-3,080=$18,920

Answer:

18 is 30% of 60

Step-by-step explanation:

Try to line up percents % and the actual numbers they represent.

number : precent

       60  is 100%

        18  is x %

cross multiply

x·60 = 100·18

divide both sides by 60 to isolate x

x = ((100·18)/60

x = 30

Answer:

2x^2 - 10x - 8.

Step-by-step explanation:

= 2(x^2 - x - 4x - 4)

= 2(x^2 - 5x - 4)

= 2x^2 - 10x - 8.

Math

Answer:

The following measurements are:

[tex]m\angle{STR}=23^\circ[/tex] (Option #4)

[tex]m{QT}=142^\circ[/tex] (Option #7)

[tex]mST=134^\circ[/tex] (Option #5)

[tex]mRQ=38^\circ[/tex] (Option #2)

Step-by-step explanation:

To begin, we can find the measure of [tex]\angle{STR}[/tex] by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

Since the intercepted arc (RS) is 46 degrees, we have:

[tex]46=2\theta\\23=\theta[/tex]

Next, we can find the measure of arc QT using the same theorem. So,

[tex]QT=2(71)\\QT=142[/tex]

Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of [tex]180^\circ[/tex]. Since the arc ST is part of the arc RST, and we know RS is [tex]46^\circ[/tex], we can set up and solve this equation:

[tex]RST = RS + ST\\180 = 46 + ST\\134 = ST[/tex]

We can use the same idea to find RQ. We know that RQT is [tex]180^\circ[/tex] and QT is [tex]142^\circ[/tex], so:

[tex]RQT = RQ + QT\\180 = RQ + 142\\38 = RQ[/tex]
