Answer:

120 in^2

Step-by-step explanation:

The surface area of the prism is the area of all faces combined.

There are four 6 in. by 2 in. rectangles and two 6 in. by 6 in. squares, so the total area is

[tex]4(6 \cdot 2) + 2(6 \cdot 6)=120[/tex] [tex]\text{in}^2[/tex].

G'(x) = 1 × g(x) × f(x) + g'(x) × x × f(x) + f'(x) × x × g(x)

G'(x) = g(x).f(x) + x.f'(x).g(x) + x.g'(x).f(x)

Thus ;

G'(3) = g(3).f(3) + 3f'(3).g(3) + 3g'(3).f(3)

G'(3) = 13×9 + 3×( - 11 )×13 + 3×( - 5 )×9

G'(3) = 117 + ( - 429 ) + ( - 135 )

G'(3) = 117 - 135 - 429

G'(3) = - 18 - 429

G'(3) = - 447

Answer:

hypotenuse ( c²) = a² + b²

- assume you're given the side a, find b:

b² = c² - a²

b² = (34)² - (16) ²

b² = 1156 - 256

b² = 900

b = √ 900

b = 30

therefore, the other leg is 30 inches.

Answer :

30 inches

Step-by-step explanation:

To determine one of the side lengths of a right triangle we can use the Pythagorean formula :

a² + b² = c²

b = 16 in

c = 34 in

a² + b² = c²

a² + 16² = 34²

a² + 256 = 1.156

a² = 1.156 - 256

a² = 900

a = √900

a = 30 in

The dimensions that would maximize the area enclosed by the fence is 30m × 60m.

where

l = length

w = width

Therefore,

The corral uses the side of a barn as one of its sides, so the fencing is required on three sides of the rectangular region. Therefore,

perimeter = L + 2w

L + 2w = 120

L = 120 - 2w

area = Lw

area = (120 - 2w)w

area = 120w - 2w²

area = -2w² + 120w

We have a quadratic equation and it is parabolic.  The leading coefficient is negative. Therefore, the parabola opens downward and the vertex is the maximum point.

The area is maximized at the vertex. Therefore,

To find the vertex, we need to have our quadratic equation in general form,

ax² + bx + c = 0

so a = -2, b = 120

w = -b / 2a

w = - 120 / 2 × -2

w = -120 / -4

w = 30

Therefore,

area = -2(30)² + 120(30)

area = 1800m²

Therefore, the maximum area we can enclose is 1800 m², the width is 30m, then the length will be 60 m because 60 × 30 = 1800 m².

Answer:

Step-by-step explanation:

We need to convert the fraction into a whole number.

We have to solve 11 + 19 first:

30/3 = 10 so we need to increase the numerator:

Answer:

90

Step-by-step explanation:

First we take 11 to other side to give:

[tex]\frac{w}{3} = 19+11[/tex]

[tex]\frac{w}{3} = 30[/tex]

Now we escalate the 3 up to give

w = 30×3

w=90

To double check we can substitute our value of w into the original equation:

[tex]\frac{90}{3}-11 = 19[/tex]    ✅

The product of numbers is calculated by multiplying them

The result of the product is 6/48

The product is given as:

3/8 x 2/6

Rewrite properly as:

[tex]\frac 38 * \frac 26[/tex]

Using the model, we have:

[tex]\frac 38 * \frac 26 = 3 * \frac 18 * 2 * \frac 16[/tex]

Rewrite as:

[tex]\frac 38 * \frac 26 = 3* 2 * \frac 18 * \frac 16[/tex]

Multiply the integers

[tex]\frac 38 * \frac 26 = 6 * \frac 18 * \frac 16[/tex]

Multiply the fractions

[tex]\frac 38 * \frac 26 = 6 * \frac 1{48}[/tex]

Multiply the integers and the fractions

[tex]\frac 38 * \frac 26 = \frac 6{48}[/tex]

2. She missed 30% of her shots, or 39 shots.

Step-by-step explanation:

1. 70% of 130 (or .7 times 130) is 91. The 70% is converted into decimals by moving the decimal 2 places to the left.
2. Out of 100%, 30% is the added percentage to make 100%. 30% of 130 (or .3 times 130) is 39. This can also be found my subtracting 91 from 130.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The yards of ribbon that were bought by Jina is 11 yard.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given that Prepaid credit card amount = $15

Also, She bought some bulk ribbon at a craft store and the price of ribbon was 21 cents per yard.

If after that purchase there was $12.69 left on the card.

Now, we can write the following details,

The amount on the credit card = $15

The amount spend on buying the ribbon = $0.21 cents per yard

The amount left on the credit card = $12.69

Further, we can write,

The amount that was used to buy the ribbon

= $15 - $12.69

= $2.31

Now, the length of the ribbon bought by Jina is,

Length of ribbon =  $2.31 / $0.21 per yard = 11 yards

Hence, the yards of ribbon that were bought by Jina is 11 yard.
