Answer:

1005 ft squared (B)

Step-by-step explanation:

The far left area:

30*15=450

The middle area:

-Since there is an eight feet being subtracted it is:

22*15=330

The last side:

-Since there is two 15's at the bottom we must subtract 30 from 45:

15*30*1/2=225

Add the area together:

450+330+225=1005

1005 ft squared

Answer:

1900

Step-by-step explanation:

hello bro how r u i think answer is 1835 but there is no option

The required mass of the proton is 1900 times the mass of the electron. Option B is correct.

Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

here,
The mass of an electron is approximately e = 9.1 x 10⁻³¹ kilograms.
The mass of a proton is approximately p = 1.7 x 10⁻²⁷ kilograms.
Now

p/e =  1.7 x 10⁻²⁷/9.1 x 10⁻³¹
p/e ≈ 1900
p = 1900e

Thus, the required mass of the proton is 1900 times the mass of the electron.

Answer:

x=2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Step-by-step explanation:

This is a linear equation, and we will need to get the variable by itself.

Let's calculate!

[tex]8+3x=14\\3x=14-8\\3x=6[/tex]

Now we divide both sides by 3. Dividing 3 by 3 is just 1, and we don't need to write the 1, and 6 divided by 3 is two! So your equation will look like this:

[tex]3/3x = 6/3\\x=2\\[/tex]

Answer:

a. 3x+6=30

b. 3(6+x)=30

Step-by-step explanation:

a. As you know, x is the unknown variable. In the first question we know that there are 3 bags that weigh the same amount, however we don't know the amount of pounds that it weighs. So we can mark it with a variable (x). Since there is 3 bags we can multiply 3 by x to get the total weight. There is a 6 pound rice bag inside, and the total weight is 30. Hence, the equation 3x+6=30.

b. In this case, we ae told that each basket contains 3 boxes. with a 6 pound rice bag, and a bag of stuffing. We will represent the weight of the bag of stuffing with an x. The weight of a single box is x+6. Since there is 3 boxes, we can multiply the entire thing by 3.

Answer:

The actual height is 4.896 m

Step-by-step explanation:

Given

[tex]Ratio= 1 : 48[/tex]

[tex]Scale\ Height = 102mm[/tex]

Required

Determine the actual height in metres

Represent the actual height with x.

So, the ratio of Scale Height to Actual Height as:

[tex]Ratio = 102mm : x[/tex]

To calculate x, both ratios must be equal

[tex]1 :48 = 102mm:x[/tex]

Convert to fraction

[tex]\frac{1}{48} = \frac{102mm}{x}[/tex]

Cross Multiply

[tex]x * 1 = 48 * 102mm[/tex]

[tex]x = 4896mm[/tex]

Convert mm to metres

[tex]x = 4896 * 0.001m[/tex]

[tex]x = 4.896m[/tex]

The actual height is 4.896 m

Answer:

The speed of light is 8.8x10⁵ times faster than the speed of sound.                                                  

Step-by-step explanation:

We can find how many times faster (R) is the speed of light than the speed of sound as follows:

[tex] R = \frac{c}{v_{s}} [/tex]

Where:                          

c: is the speed of light = 3x10⁸ m/s

[tex]v_{s}[/tex]: is the speed of sound = 340 m/s (the value given in the statement, 3.4 m/s, is wrong)

[tex]R = \frac{3 \cdot 10^{8} m/s}{340 m/s} = 8.8 \cdot 10^{5}[/tex]

Hence, the speed of light is 8.8x10⁵ times faster than the speed of sound.

The solution is, the scale factor on the map is 557.

A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.

here, we have,

from the given diagram we get,

in the map it is mentioned that,

1 unit = 557 miles.

now, we have to find the scale factor,

i.e. the number, which we have to multiply with the the unit of distance in the map to get the original distance of the two places.

now, we have,

so, it means that the x unit = 557 * x miles.

i.e. the scale factor = 557

Hence, The solution is, the scale factor on the map is 557.

Hope this helps

Answer:

1. 115. If q=4, then the equation tells us that 0.1d+(0.25)⋅4=12.5. Subtracting 1 from both sides gives 0.1d=11.5, so d=115.

2. 100. If q=10, then the equation tells us that 0.1d+(0.25)⋅10=12.5. Subtracting 2.5 from both sides gives 0.1d=10, so d=100.

3. Yes. If you know the number of quarters, then you can determine the number of dimes from the equation. We can even write the equation in a way that shows this: d=125−2.5q. The expression 125−2.5qrepresents the output—it is the rule that determines the output d from a given input q.

Answer: $3.53

Step-by-step explanation: 15 percent off can be thought of as 85% of the original value because 100-15 is 85. this means that if x is the value of the original shirt, .85x=3

divide by .85

x=3.5294

which is about $3.53

Answer:

You will pay $12 for a item with original price of $15 when discounted 20%. In this example, if you buy an item at $15 with 20% discount, you will pay 15 - 3 = 12 dollars.
