Answer:

the answer should be 2.5

To find the lateral area of the given rectangular pyramid, calculate the perimeter of the base, determine the slant height using the Pythagorean theorem, and then apply the lateral area formula. The lateral area is approximately 45.4 cm².

To find the lateral area of a regular rectangular pyramid with base edge length 2.5 cm and height 9 cm, follow these steps:

Thus, the lateral area of the pyramid is approximately 45.4 cm².

Answer:

D

Step-by-step explanation:

2 multiplying by any number even or odd=even number

Final answer:

The correct answer is D) 2(ab + 1), because multiplying an odd number (ab + 1) by 2 results in an even number.

Explanation:

The question asks which expression must be even if integers a and b are even. We know that the product of two even numbers is always even. Therefore, ab is even.

When we add 1 to an even number, the result is odd, so ab + 1 is odd. Multiplying by 3, as in option C, won't change the oddness, so 3(ab + 1) is also odd. The expression in option E, a2 + b2 + 1, will be odd for the same reason - the sum of even squares is even, and adding 1 makes it odd.

However, option D multiplies the odd number ab + 1 by 2, guaranteeing that the result is even regardless of the values of a and b since any number multiplied by 2 is even. Thus, the correct answer is D) 2(ab + 1).

Answer:

2/3

Step-by-step explanation:

Calculators help :)

To divide 2 1/2 by 3 3/4, convert the mixed numbers to improper fractions, change division to multiplication of the inverse, multiply, and simplify the result to 2/3.

To divide and simplify the expression 2 1/2 divided by 3 3/4, we begin by converting the mixed numbers into improper fractions. The mixed number 2 1/2 becomes 5/2 (2 times 2 + 1), and 3 3/4 becomes 15/4 (3 times 4 + 3).

Next, we use the rule for dividing fractions: invert the second fraction and change the division to multiplication. Therefore, the division becomes 5/2 times 4/15. We can now multiply the numerators together and the denominators together, resulting in 20/30.

To simplify, we can reduce the fraction by dividing both the numerator and the denominator by the greatest common factor, which is 10. Simplifying gives us 2/3, the final answer.

Answer:

See below

Step-by-step explanation:

1-0+0-2+1=0, so since 0/11=0, it's divisible by 11

The rule for divisibility by 11 is that you subtract then add then subtract then add and so on, and if you get a number divisible by 11 or equal to 0, then it's divisible by 11.

Hope that made sense.

Answer:

10 =8

Step-by-step explanation:

The two angles are vertical angles and we know that vertical angles are equal

110 = 8x +30

Subtract 30 from each side

110-30 = 8x+30-30

80 = 8x

Divide each side by 8

80/8 = 8x/8

10 =8

Answer: adjacent and hypotenuse

Step-by-step explanation: Cos theta is adjacent/Hypotenuse

Final answer:

Inverse cosine is used to find an angle measure when we know the length of the adjacent side and the hypotenuse in a right triangle.

Explanation:

The inverse cosine function, also known as arccosine, is used to find a given angle measure when we know the length of the side adjacent to the angle and the length of the hypotenuse of a right triangle. The cosine of an angle in a right triangle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. By using the inverse cosine function, we can find the angle whose cosine is the given ratio. This is particularly useful in trigonometry for solving right triangles or when dealing with any scenario where angle and side lengths are related through the cosine ratio.

In mathematical terms, if we have a right triangle with an angle labeled as θ (theta), and we know the lengths of the side adjacent to θ (adjacent) and the hypotenuse (hypotenuse), the cosine of θ is given by-

cos(θ) = adjacent / hypotenuse

To find the angle measure θ based on the ratio of these two sides, we would compute-

θ = arc cos(adjacent / hypotenuse).

Answer:

the outlier is 20 and 24

Step-by-step explanation: An outlier, in mathematics, statistics and information technology, is a specific data point that falls outside the range of probability for a data set. In this Case 20 and 24 are outliers because they are not in the range of 58, 59, 63, 63, 65, 66. :) your welcome.

Answer is B! Correct on exam!

Step-by-step explanation:

1. Identify the values for a, h, and k: a= 1/2 h= -1 k= 4. (Remember that the sign of h changes!)

2. Determine vertex: (-1,4)

3. Determine x and y for focus: X= -1 (same as vertex) y= K + 1/4(a)

Substitute what we know into that formula: y= 4 + 1/4(1/2)

y= 4 + 1/2 so y= 4 1/2.

4. Determine directrix: y= k - 1/4(a) ]

Substitute in what we know: y= 4 - 1/4(1/2)

y= 4-1/2 so y= 3 1/2

The focus and directrix of the parabola are (-1, 9/2) and y=7/2 respectively.

The given function is y = 1/2(x+1)² + 4.

We need to find the focus and directrix of the parabola.

A parabola is a set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Up

Directrix: Use the vertex form to find the directrix

y=7/2

Focus: Use the vertex form to find the focus.

(-1, 9/2)

Axis of symmetry: x=-1

The coordinates to plot the graph are as follows:

(-3, 6), (-2, 9/2), (-1, 4), (0, 9/2) and (1, 6).

Therefore, the focus and directrix of the parabola are (-1, 9/2) and y=7/2 respectively.

Answer:

b. $9000

Step-by-step explanation:

Quick way of doing this:

10% is one-tenth. 10% of $180,000 is $18,000.

5% is half of 10%, so it's half of $18,000.

Answer: b. $9000

Conventional way of doing this:

To find a percent of a number, multiply the percent by the number. To change the percent to a decimal, move the decimal point of the percent two places left.

5% of $180,000 = 5% * $180,000 = 0.05 * $180,000 = $9,000

Answer: c. $9000

Mrs. Henderson's commission for selling a house worth $180,000 is $9000.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Mrs. Henderson sells houses. She gets a 5% commission on all sales.

∴ His commission for selling a house worth $180,000 is 5% of  $180,000 which is,

=(5/100)×180000.

= $9000.

Step-by-step explanation:

Answer:

-25

Step-by-step explanation:

(-4 + 5n) × 3= 7n - 212

-12 + 15n = 7n - 212

8n = -200

n = -25

Answer:

The number is -25

Step-by-step explanation:

(-4 +5n)*3 = 7n-212

Distribute

-12 +15n = 7n -212

Subtract 7n from each side

-12 +15n-7n = 7n-7n -212

-12 +8n = -212

Add 12 to each side

-12+12 +8n = -212+12

8n = -200

Divide each side by 8

8n/8 = -200 /8

n =-25

Answer:

700 cubic feet

Step-by-step explanation:

Volume of scale model = 35 cubic feet

ratio of the dimensions of the model to the dimensions of the store was 1:20

Therefore

dimensions of the model/ dimensions of the store = 1/20

we know that in scaling

dimensions of the model/ dimensions of the store = Volume of scale model / volume of the actual department store

Now substituting the value of scale model in the above ratio equation we have

1/20 = 35/volume of the actual department store

=> volume of the actual department store = 35*20 = 700

Therefore volume of the actual department store is 700 cubic feet
