I am a 2-digit number. The sum of my digits is 11. I am divisible by both 4 and 7

Answer:

3.08

Explanation:

The first 3 numbers (from left to right) are the ones counted as 3 significant figures. You alreadty start of 5 significant figures. What you do is count the numbers, from left to right, and once you get to the number you're finding (in this case the 3rd significant figure), then you look at the number to the right of it and see if it's over or under 5. Depending on which one it is will determine wiether you round up or stay at the same point.

Answer:

future value

Step-by-step explanation:

The value of the goal is called future value. Then the correct option is B.

The worth of a present asset at a certain stage in the future, depending on an estimated growth, is called future value (FV).

The FV estimate allows investors to make a reasonable assumption about equity investment earnings.

The area of the sector is 84.78 square units

From the question, we are to determie the area of the sector.

The area of a sector can be calculated by using the formula,

[tex]A= \frac{\theta}{360}\times \pi r^{2}[/tex]

Where A is the area of the sector

θ is the central angle

and r is the radius

From the give information,

θ = 120°

r = 9

and π = 3.14

Putting the parameters into the formula, we get

[tex]A = \frac{120 ^\circ}{360 ^\circ} \times 3.14 \times 9^{2}[/tex]

[tex]A = \frac{1}{3} \times 3.14 \times 81[/tex]

[tex]A = 3.14 \times 27[/tex]

A = 84.78 square units

Hence, the area of the sector is 84.78 square units

Answer: radius = 6.18 (I don't know what solutions you have, but the actual answer for the radius is about 6.18 cm so which ever is closest.)

Step-by-step explanation:

the area of a circle is \pi  r^{2}

*rewrite your equation solving for radius

r=\sqrt{A/\pi } =\sqrt{120/\pi } = 6.18

To find the Radius of a circle with an area equal to the area of a rectangle, multiply the length and width of the rectangle to get its area, then use the formula A = πr² to solve for the radius.

To find the Radius of a circle with an area equal to the area of a rectangle, we need to find the area of the rectangle and then calculate the radius of the circle using that area.

The area of the rectangle is found by multiplying the length and width, which in this case is 15 cm * 8 cm = 120 cm².

The area of a circle is given by the formula A = πr², where A is the area and r is the radius. Since the area of the rectangle is equal to the area of the circle, we can set up the equation 120 cm² = πr².

Solving for r, we get r ≈ 6.94 cm (rounded to two decimal places).

Final answer:

The result of adding 30.09, 5.55, and 80.761 and rounding to the least number of decimal places (two decimal places) is 116.40, with four significant figures.

Explanation:

To solve the problem 30.09 + 5.55 + 80.761 and express the answer with the correct number of significant figures, you should first perform the addition and then round the result to the least number of decimal places of any number in the sum. The number with the least number of decimal places is 5.55 (two decimal places).

Here's the step-by-step calculation:

Add the numbers: 30.09 + 5.55 + 80.761 = 116.401

Round to two decimal places (because of 5.55): 116.40

So, the final result is 116.40, which has four significant figures and two decimal places.

Answer:

5

Step-by-step explanation:

2(3x + 6) = 42

(3x + 6) = 42/2

(3x + 6) = 21

3x + 6  = 21

3x  =  21 - 6

3x  =  15

x = 1/3

x = 5

Answer:

The answer would be x=5

Step-by-step explanation:

2(3x+6)=42

so what you're gonna do is use the distributive property, so you would multiply 2 and 3x, and 2 and 6. so then you would have:

6x+12=42

Now you want to get rid of the twelve so you can solve for x. So you are going to subtract 12 from 12 and 42. So now you have:

6x=30

Next you're going to divide 6x and 30 by 6. So you would have x=5

To find the length of line AB, use the midpoint formula and solve for AB.

To find the length of line AB, we can use the midpoint formula. Given that point T is the midpoint of line AB, we can set up the equation:

(AT + TB) / 2 = AB

Substituting the given values:

((3/4)x + 6 + (1/2)x + 9) / 2 = AB

Simplifying the equation:

(5/4)x + 15 / 2 = AB

(5/4)x + 7.5 = AB

Therefore, the length of line AB is (5/4)x + 7.5.

The product of these slopes is -1

Step-by-step explanation:

The slope of perpendicular  lines are negative reciprocal.This means that when you multiply the two slopes you get -1.

To find slope of a line you apply;

m=change is y-axis values/change in x-axis values

Given that there are two lines, PQ and P'Q' then to find slope you follow;

Line PQ where P(a,b) and Q (c,d)  slope,m= (d-b / c-a )

Final answer:

The letter J is formed by the opposition movement of the thumb toward the fingers of the same hand.

Explanation:

The subject of this question is Biology, specifically the anatomy of the hand and the movement of the thumb.

The letter J is formed by sticking up the smallest finger and folding all the other fingers into the palm of your hand with the thumb folded over them. This hand movement is an example of the opposition movement of the thumb toward the fingers of the same hand, which allows us to grasp and hold objects.

The thumb joint, which can move back and forth and up and down, but more freely than the wrist or fingers, plays a key role in the formation of the letter J.

a.  [tex]\frac{1}{20}[/tex] liters per glass

b. 50 milliliters

To find the amount of water in each glass, divide the total amount of water by the number of glasses, resulting in [tex]\frac{1}{20}[/tex] liters per glass. To express this in milliliters, multiply by 1000 to get 50 milliliters per glass.

a. To find the amount of water in each glass, divide the total amount of water ([tex]\frac{1}{4}[/tex] liters) by the number of glasses (5): [tex]\frac{1}{4}[/tex] ÷ 5 = [tex]\frac{1}{20}[/tex] liters per glass. Drawing a visual representation can help understand this partitioning.

b. To express the amount in milliliters, we know that 1 liter is equal to 1000 milliliters. So, [tex]\frac{1}{20}[/tex] liters per glass = ([tex]\frac{1}{20}[/tex]) * 1000 milliliters = 50 milliliters per glass.

To distribute the 250 milliliters equally into 5 glasses, we divide 250 milliliters by 5. This calculation results in:

250 milliliters ÷ 5 = 50 milliliters per glass.

To convert the amount in milliliters back to liters for each glass, recall that 1,000 milliliters is equivalent to 1 liter. Therefore, 50 milliliters is the same as 0.05 liters (since 50 divided by 1,000 equals 0.05).

Answer:

1 2/3 yards of yellow fabric.

Step-by-step explanation:

5 1/3 = 3 2/3+y

5 1/3 - 3 2/3 = y

16/3 - 11/3 = y

5/3 = y

y = 1 2/3 yards of yellow fabric.

Answer:

y= # yellow fabric yards

5 1/3= 3 2/3+ y

Convert to improper fractions

((5*3)+1)/3= ((3*3)+2)/3 + y

16/3=11/3+y

Subtract both sides by 11/3

Answer:

B = 68°  and  C = 22°

Step-by-step explanation:

Let angle B's measure be B and angle C's measure be C.

Also note that complementary means that they sum to 90.

Now:

The m∠B is two more than three times the measure of ∠C:

we can write:

B = 3C + 2

If ∠B and ∠C are complementary angles:

B + C = 90

Putting 1st equation in 2nd, we get:

B + C = 90

3C + 2 + C = 90

4C = 90 - 2

4C = 88

C = 88/4 = 22

Now B = 3C + 2, so

B = 3(22) + 2 = 68

Hence, B = 68 degrees and C = 22 degrees

The average temperature of 7 degrees below normal can be represented as the integer '-7'. This is because in mathematics, a 'below' situation often equates to a negative value.

The situation describes 'an average temperature of 7 degrees below normal'. In the context of integers, 'below' generally refers to a negative value. Hence, we would represent this situation with the integer '-7'. This is because a below normal temperature is often regarded as a decrease or loss, which is conventionally represented in mathematics as a negative value.
