Answer: 109886 employees

Step-by-step explanation:

26.3% of x = 28900

  x = 28900 / 26.3%

  x = 28900 / 0.263

  x = 109885.932

*Rounded to the nearest whole integer

  x = 109886

Answer:

546

Step-by-step explanation:

Sofia slept 546 miles and was awake for 45% which is 294 of the miles.

You can find this by finding 1%, and that would be 8.4. (You get 1% from dividing 100 from the 100% number.) Then you multiply it by 65 so now you get 546.

If the total length of the trip was 840 miles, then Sofia had traveled 294 miles before she fell asleep.

Given that,

If Sofia slept through the last 65% of the trip and the total length of the trip was 840 miles,

then she stayed awake for the first 100% - 65% = 35% of the trip.

Here, we have to calculate the distance she traveled before falling asleep, we can use the percentage of the total distance:

Distance traveled by Sofia = 35% of 840 miles

Distance traveled by Sofia = 0.35 * 840

Distance traveled by Sofia = 294 miles

So, Sofia had traveled 294 miles before she fell asleep.

Answer:

125 cards

Step-by-step explanation:

I did this by dividing 100 by 4, since there is 100 percent in total. This gets 25. I then multiplied 25 by 5, because 4 percent = 5 cards. Basically for every 4 percent for every five cards. take it as the amount of 4 percents, there are the same amount of 5 cards.

Answer:

San Francisco is the fastest

Step-by-step explanation:

The reason why is because you have to get the hours the same soooo...

You can get all of the hours to 12. So Ph= 3hours so 3x4=12 and what you do on one side you have to do on the other. So 1689x4=6756 next M=2 hours so to get it to 12 you do 2x6=12. Then 913x6=5478. Next San=4 hours

4x3=12 next 3x2556=7668 Sooooooo.... Put the data together

In 12 hours Ph goes 6756 miles

In 12 hours M goes 5478 miles

In 12 hours San goes 7668 miles

So the answer is San because it has the biggest number

Answer:

Angle ABD is 16 degrees and Angle DBC is 74 degrees

Step-by-step explanation:

Question 6. x+9+11x-3=90. 12x+6=90 -6 on both sides and 12x=84 divide each side by 12 and x= 7 angle ABD is x+9 so 7 +9= 16. Angle measure of ABD is 16 degrees. Measure of angle DBC is 11x -3 so 11 times 7=77. 77-3= 74. So the measure of angle DBC is 74 degrees and this answer is right because they both add up to be 90 degrees. Hope this helped! :)

The answers to the questions are given below.

        where [a] is side length of cube.

        where [h] is prism height, [w] is its width, and [L] is its length.

We have the question as shown in the figure.

Cube with side length (1/5) :

Volume = (1/5 x 1/5 x 1/5) = 1/125 cm³

Prism of dimensions (L = 1/5, B = 2/5, H = 3/5) :

Volume = (1/5 x 2/5 x 3/5) = 6/125 cm³

Cube with side length (2/5) :

Volume = (2/5 x 2/5 x 2/5) = 8/125 cm³

Prism of dimensions (L = 3/5, B = 4/5, H = 3/5) :

Volume = (3/5 x 4/5 x 3/5) = 36/125 cm³

Therefore, the answers to the questions are given above.

Answer:

30

Step-by-step explanation:

Given:

QR= 45 mm

RS= 15, (1/3 of QR is 15).

QT is 90 mm

We must find ST.

Equation:

Use Segment Addition Postulate Theroem,

QR+RS+ST=QT

Subsitue the values we know

45+15+ST=90

60+ST=90

ST=30So ST length is 30 m

Number 1: He needs 5x3 to get 15 balloons, but since he need more than provided, he needs one more pack.

Number 2: He played 2 rounds, and each round got 4 points, 4x2=8.

Number 4: If she had 8x8=64, and subtracted 10, she has 54.

Number 6: So you should make the fractions improper fractions, (fractions that have a numerator thats more than the denominator) so 2 1/4 = 9/4 and 3 1/4 = 13/4 and then multiply 13 x 9= 117 and then 4x4= 16 so you have 117/16 and then when you simplify it you get: 7 5/16

Answer:

The two possible measures tobproduce a ️ are ''Three angles: 62, 32°, and 84°" & "Three sides: 4cm, 7cm, and 9cm"

The triangle is formed by two sides of 4 cm and 7 cm with an angle of 54° between those two sides

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Two sides of 4 cm and 7 cm with an angle of 54° between those two sides would produce two possible triangles.

This is because if the angle is between the two sides, the two sides can be positioned in two different ways to form two distinct triangles, whereas if the angle is not between the two sides, only one triangle can be formed.

The other measures listed do not provide enough information to determine if there are one or two possible triangles.

Hence , the triangle is solved

Answer:

The first option, 132.7 cm²

Step-by-step explanation:

The area of a circle can be found with A = πr²

A = πr²

A = π(6.5)²

A ≈ 132.73

A ≈ 132.73 cm²

-> 132.7 cm² <-

Answer:

Step-by-step explanation:

You only had to solve this problem to use a circle's area.

[tex]\text{Area of a circle: }\sf{A=\pi r^2}[/tex]

Radius of this circle is 6.5 cm.

A=πr²

A=π(6.5)²

Solve.

A=π(6.5)²

A=132.73

To get the correct answer, remember to use the centimeter.

A=132.7cm²

Therefore, the correct answer is

A. 132.7cm².

The absolute deviation of 16 in the given data set, {19, 16, 4, 9, 7}, is: B. 5.

The absolute deviation of a data point in a data set, is the distance of that data point from the mean of the data set.

Find the mean of the data set:

Mean = (19 + 16 + 4 + 9 + 7)/5 = 55/5

Mean = 11

16 - 11 = 5

There are  8 apples and 10 oranges in a basket.  In this scenario, we can see that ratio of apples to oranges is 4:5.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

A ratio is a fraction that may compare part to whole or part to part. For example, suppose in a class, the ratio of boys to girls is 4 to 5. It means that the number of boys divided by the number of girls is a fraction that, in its simplest form, equals 4 over 5.

Same as there are 8 apples and 10 oranges in a basket. this is also represented perfectly in terms of ratio.

Therefore, In a basket, there are 10 oranges and 8 apples. We can observe that the ratio of apples to oranges in this situation is 4:5.
