A box of bananas was bought for $50 and was sold for a 15% loss. What is the selling price of the bananas?

Answer:

I think 30

Step-by-step explanation:

I don't know I could be wrong

Answer:

10

Step-by-step explanation:

let your current age be x.

mother's age=48

3(x+6)=48

3x+18=48

3x=30

x=10

To solve this problem, we simply need to convert the distance

Like we already established earlier, we just need to convert the distance unit from miles to inches

But given that

[tex]1mi = 63360in[/tex]

Let us find how many inches will be in 65 miles.

In this case, simply multiply 65 by 63360 to find the actual distance in inches.

[tex]65 * 63360 = 4118400in[/tex]

The distance on her map will be 4118400 inches on her map.

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

y = 2x + 4     Substitute this for y in the second equation

6x - 3y = -12

6x - 3(2x + 4) = - 12  Substitute this for y for 2x + 4

6x - 3(2x) -3(4) = -  12    Distributive property

6x - 6x - 12 =  - 12

(6x - 6x) -12 = - 12   like terms together

 0 - 12 = - 12       Simplify

-12 = -12        True equation so x is equal to any number  and you have the same equation  

Answer:

B

Step-by-step explanation:

General equation

y = mx + b

m = the slope

b = the y intercept

Slope

y = -2x + b

y intercept

use the point to get the y intercept.

x = 1

y = - 4

Subsitute these values into the incomplete equation under slope

-4 = -2(1) + b

-4 = - 2 + b            Add 2 to both sides

-4+2 = b

b = - 2

Answer

y = -2x - 2

Answer:

y = -2x - 2

Step-by-step explanation:

When given a point and a slope, we use slope-intercept formula:

y - y1 = m (x - x1)

m = slope  point: (1,-4)

y - y1 = m (x - x1)

y - (-4) = -2 (x - 1)

y + 4 = -2x + 2

  - 4          - 4

y = -2x - 2

Answer:

2.

Step-by-step explanation:

If it was 14, 24.5, or 28, that side of the trapezoid would've been much longer.

Answer:

I believe your answer would be 2

Step-by-step explanation:

Using the same method as I explained in your previous triangle question I assumed the bigger quadrilateral is an expanded version of the smaller one.

Step 1:

Divide 14 by 4

14/4=3.5

Step 2:

Divide 7 by your 3.5

7/3.5=2

This means that the side of x should be 2 because each side is squished by a factor of 3.5 and expanded by this factor to get to the big shape.

Answer:

Division is the separation of something (a number) into equal parts.

Step-by-step explanation:

Division is the separation of something (a number) into equal parts. In other words, it's the opposite of multiplication, which is the repeated addition of something (a number).

Probably the best way to explain division is with an example. Say I want to compute the following:

10 / 2

"10" means I have 10, and the "/ 2 means" that I want to seperate 10 into equal groups of 2. To do that, I will count how many groups of 2 I can have in 10. 2, 4, 6, 8, and 10 make 5 equal groups of 2. Therefore,

10 / 2 = 5.

Division can also result in remainders, or leftovers after division. This is because somethimes, numbers don't divide evenly. Take for instance this example:

10 / 3

I know that 3 isn't a multiple of 10, but I can still attempt to divide it. 3, 6, 9, three groups ... wait ..., I have only 1 left. What do I do with this 1? Well, it is a remainder now because it is left over:

10 / 3 = 3 and a remainder of 1 ( or 3 r1).

I'm sorry if this is a bad explanation, but I am not a big fan of using visuals online when teaching math. Yet, I have done my best to explain what division is (in abstract form no less), and I hope you can figure it out if you haven't yet in the future.

Answer:

a) 0.11

b) 60

Step-by-step explanation:

a)

Probability that a 3 will be rolled = frequency of 3 / total frequency

frequency of 3 = 11

total frequency = 100; 12 + 35 + 11 + 23 + 7 + 12 = 100

= 11/100

= 0.11

Answer: 0.11

b)

Probability of getting 6 = 12/100 = 0.12

Now, the dice is rolled over 500 times:

total times = 0.12 × 500

= 60 times

Answer: 60

Answer:

2.8

Step-by-step explanation:

By the angle bisector theorem, [tex]\frac{AC}{AB}=\frac{CD}{DB}.[/tex] Plugging in the values from the diagram gives:

Solving gives

Answer:

x = 20, y = 3

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{TU}{QR}[/tex] = [tex]\frac{UV}{RS}[/tex] ( substitute values )

[tex]\frac{x}{4}[/tex] = [tex]\frac{30}{6}[/tex] = 5 ( multiply both sides by 4 )

x = 20

and

[tex]\frac{QS}{TV}[/tex] = [tex]\frac{RS}{UV}[/tex] ( substitute values )

[tex]\frac{y}{15}[/tex] = [tex]\frac{6}{30}[/tex] ( cross- multiply )

30y = 90 ( divide both sides by 30 )

y = 3

The area of a shape is the amount of space it occupies.

The dimension of the paper is given as: 12-inch by 8-inch

So, its area is:

[tex]Area = 12 * 8[/tex]

[tex]Area = 96[/tex]

Hence, the area of the paper is 96 square inches

The dimensions of the 4 right triangles are: Two 2 inches by 9 inches, and two 3 inches by 6 inches

So, the combined area is:

[tex]Area = 0.5(2 * 2 * 9 + 2 * 3 * 6)[/tex]

[tex]Area = 36[/tex]

Hence, the combined area of the triangle cutouts is 36 square inches

The area of the parallelogram is the difference between the areas of the paper and the four right triangles.

So, we have:

[tex]Area = 96 - 36[/tex]

[tex]Area = 60[/tex]

Hence, the area of the parallelogram is 60 square inches

The base is given as 9.22

So, we have:

[tex]Area = Base * Altitude[/tex]

This gives

[tex]60 = 9.22* Altitude[/tex]

Divide both sides by 9.22

[tex]Altitude = 6.51[/tex]

Hence, the altitude of the parallelogram is 6.51 inches

Step-by-step explanation:

Answer:

x = 23

( x + 16 ) + ( 3x - 1 ) + 6x + 5x = 360°

x + 3x + 6x + 5x + 16 - 1 = 360°

15x + 15 = 360°

15x = 360° - 15

x = 345 ÷ 15

x = 23

Step-by-step explanation:

since the other angles are equal to each other, both triangles, TQR and TSR, are identical. they are just oriented differently.

but that also means that both angles, Q and S, are identical too.

so,

2x² = 3x² - 64

64 = x²

x = 8

and therefore, both angles are 128°.

Answer: Area - 17a^2 b, Perimeter - 10a^2 + 10 b

Step-by-step explanation:

To find the area, we can divide the figure into 3 separate rectangles.

Then, we find the area of each separate rectangle and add them together.

Area = a^2b + a^2b + 15a^2b

Area = 17a^2 b

The perimeter is the sum of all sides

Perimeter = a^2 + b + 3a^2 + b + a^2 + 4b + 5a^2 + 4b

Perimeter = 10a^2 + 10 b

Answer:

17"

Step-by-step explanation:

Isosceles means there are two equal sides in this triangle.

So the height not only is perpendicular to the base, but also cuts the base in half.

Each half is 15 inches. (30÷2=15) See image.

These half triangles formed by the height, are right triangles. You can use Pythagorean theorem or if you're familiar with the pythagorean triple 8, 15, 17, you will find the length of the side is 17 inches. See image.

Answer:

10w + 45w = 55w

120 + 25 = 145

So the answer is 55w + 145

Answer:

6 +x

Step-by-step explanation:

Let the number = x

Sum of 14 and a number = 14 +x

8 fewer than (14 + x )= 14 + x - 8 = 6 +x

Answer: 14 + x - 8 (can also be 6 + x)

Step-by-step explanation:

8 fewer means we're subtracting 8, which is -8

Sum of 14 and a number would be 14 + x

All of this combined would be 14 + x - 8 but if you want to simplify it, you can subtract 8 from 14 and get 6. This would be 6 + x.

Answer: 3.5

Step-by-step explanation:

It is an intersection of a tangent and a secant.

122=9(9+2a)
144=81+18a63= 18a3.5=a

Took test as well!

The numerical value of 'a' in the secant segment of the circle is 3.5.

The secant-tangent power theorem states that "if a tangent and a secant are drawn from a common external point to a circle, then the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment."

It is expressed as:

( tangent segment )² = External part of the secant segment × Secant segment.

From the diagram:

tangent segment = 12 ft

The external part of the secant-segment = 9 ft

Secant segment = ( a + a + 9 ) = 2a + 9

To determine the value of 'a', we use the secant-tangent power theorem.

12² = 9 × ( 2a + 9 )

Solve for 'a':

144 = 18a + 81

144 - 81 = 18a

63 = 18a

a = 63/18

a = 3.5

Therefore, 'a' has a value of 3.5.

Option C) 3.5 is the correct answer.
