Answer:

16 feet

Step-by-step explanation:

We use Pythagorean Theorem to find the height.

leg of triangle=  height of ladder = 15 feet

The hypotenuse of the formed triangle  = length of ladder = L

base = 6 feet

What is length of ladder?

L^2 = 15^2 + 6^2 = 225 + 36 = 261

L = root(261)  = 16.155 feet

Answer:

(4) (M∠1 + m∠2) = 180 and (m∠3 + m∠4 + m∠2) = 180

Step-by-step explanation:

The correct equation which represent Mya's claim must be true is,

⇒ m ∠1 + m ∠2 = 180°

And, m ∠3 + m ∠4 + m ∠2 = 180°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degree.

Given that;

Mya claims that,

⇒ m ∠3 + m ∠4 = m ∠1

We know that;

Sum of all interior angles in triangle are 180 degree.

And, Sum of opposite angles of a triangle is equal to its exterior angle.

Hence, We get;

The correct equation which represent Mya's claim must be true is,

⇒ m ∠1 + m ∠2 = 180°

And, m ∠3 + m ∠4 + m ∠2 = 180°

Answer:

11 gallons of gas is needed to travel 231 miles.

Step-by-step explanation:

We can set up a proportion for this problem.

For every 62 miles, you use 3 gallons of gas.

[tex]\frac{62}{3}*\frac{231}{?}[/tex]

Now, let's cross multiply.

[tex]\frac{693}{62}[/tex] ≈ [tex]11[/tex]

So, you will need about 11 gallons of gas to travel 231 miles.

Step-by-step explanation:

Let pineapple be P.

Let Strawberry be S.

Let Grape be G.

Let Watermelon be W.

3 pineapples equal 1 strawberry:

3P = S ____________ (1)

1 strawberry times 1 equals 1 grape:

S * 1 = G

S = G_____________(2)

2 grapes equal 24:

2G = 24

=> G = 24 / 2 = 12

=> From (2), S = 12

1 watermelon plus 1 pineapple equals 6:

W + P = 6_________________ (3)

From (1):

P = S / 3 = 12 / 3 = 4

Putting this in (3):

W + 4 = 6

=> W = 6 - 4 = 2

1 grape plus 1 strawberry plus 1 watermelon will be:

G + S + W

= 12 + 12 + 2

= 26

The answer is 26.

Step-by-step explanation:

Answer:

A) (-2,2) lies on both lines

Step-by-step explanation:

Your answer would be the first option, (-2, 2).

We can solve this system of equations by adding them together, as the +x and -x will cancel:

3y + x = 4

+2y - x = 6

5y = 10

y = 2

Now we can find the x value by substituting the y value into one of the equations:

3(2) + x = 4

6 + x = 4

x = -2

Therefore your answer is (-2, 2). We know that it is the first option and not the last option because the point (-2, 2) does lie on both lines as it satisfies both equations when substituted in.

I hope this helps!

Answer:

Examples are: (-1,1), (-2,1), and (-3,1).

Step-by-step explanation:

The second quadrant on a coordinate plane is located in the top left.

Compounding interest monthly on a bank's savings account results in the annual interest being divided into 12 parts and applied each month, leading to a greater amount of compound interest as interest is earned on previously accumulated interest more frequently.

When a bank's savings account pays a certain percentage of interest per year and compounds monthly instead of yearly, two things happen:

The interest gets divided into 12 parts, since there are 12 months in a year. For a 3% annual rate, the monthly rate becomes 0.25% (3% divided by 12).

The smaller monthly interest rate is applied more frequently (12 times a year), which results in compound interest. This means interest is earned not only on the initial deposit (the principal) but also on the interest accumulated from previous months. The end result is that your balance grows at a faster rate compared to yearly compounding because you're earning interest on top of interest more frequently.

The given expression for the amount after t years is P(1 + I/n)¹nt. If n increases, the value inside the parentheses becomes closer to 1, but since it's raised to the power of nt, the overall effect is that the compound interest increases the total amount more quickly than if it were compounded annually (yearly compounding).

3. The prisms are congruent, so they have the same base, height, and volume.

Volume of a prism is:

V = Ah

Plugging in values and solving for A:

90 in³ = A (15 in)

A = 6 in²

4. The cylinders are congruent, so they have the same radius, height, and volume.

Volume of a cylinder is:

V = πr²h

Plugging in values and solving for h:

176π cm³ = π (4 cm)² h

h = 11 cm

Answer:

Option D is correct.

Step-by-step explanation:

As commutative principle 2x7x6 = 7x2x6

Hope this helps!

:)

The required form of the given expression is obtained as 7 × 2 × 6. The correct option is (D).

The commutative property for multiplication states that the order of multiplication is not a necessary condition to change the product,

For example the products obtained from both the expressions 2 × 3 and 3 × 2 are the same.

The given expression is 2 × 7 × 6.

As per the commutative property the order of multiplication does not change the product.

Thus, the given expression can be written as,

7 × 2 × 6

Hence, the given expression can be rewritten as  7 × 2 × 6.

3. No, her exponent should be a negative value✅

4. No, when evaluating 36, she should have found the product of 6 and 3❌

You multiply the numerators (top numbers) and separately multiply the (bottom numbers) denominators.

numerator (top number): 2 * 1 = 2

        b.  If the decimal is being moved to the left, the exponent will be positive.

Final answer:

The scientific notation of 0.05 is 5 x 10^-2, which represents the number as a product of 5 and 10 raised to the power of -2.

Explanation:

The scientific notation of 0.05 is written by expressing the number as the product of a number between 1 and 10 and a power of ten. For the number 0.05, we move the decimal point two places to the right to get the number between 1 and 10, which is 5. Then, we use a power of ten to show how many places we moved the decimal point. The scientific notation of 0.05 is therefore 5 x 10-2.

Answer:

[tex]l = 100\,m[/tex] and [tex]w = 40\,m[/tex]

Step-by-step explanation:

The formulas for the area and perimeter of a rectangle are, respectively:

[tex]A = w\cdot l[/tex]

[tex]p = 2\cdot (w + l)[/tex]

The perimeter is equal to:

[tex]p = 2\cdot (50\,m + 90\,m)[/tex]

[tex]p = 280\,m[/tex]

Area is likewise equal to:

[tex]A = (50\,m)\cdot (90\,m)[/tex]

[tex]A = 4500\,m^{2}[/tex]

Then, equations are now described:

[tex]A = w \cdot l[/tex]

[tex]140\,m = w + l[/tex]

Likewise, the equation of area is simplified afterwards:

[tex]A = (140\,m - l)\cdot l[/tex]

[tex]A = 140\cdot l - l^{2}[/tex]

The area is reduced inasmuch as length is increased. Let assume that length is 100 meters. The length and width are described herein:

[tex]l = 100\,m[/tex] and [tex]w = 40\,m[/tex]

Answer:

59.85714285714286‬ miles a day ≈ 60 miles a day

Step-by-step explanation:

To find this, we'd have to make the weeks into days.

2 weeks * 7 days = 14 days

Now we need to divide the miles traveled by the days:

838/14=59.85714285714286‬ miles a day or about 60 miles per day

Answer:

~ 60 days

Step-by-step explanation:

We have 2 weeks. Since there are 7 days a week, 2 weeks is 14 days.

To find the number of miles walked per day, we need to divide the total number of miles by the total number of days:
