Answer:

She could  make the triangle smaller by making the same triangle but smaller and add the same sides to the small triangle.

scale factors she could use to make the triangle smaller is [tex]\frac{1}{2}[/tex]

Given :

Priya drew a triangle with the side lengths 3, 4, 5

Given options are :

1.) 1/2

2.) 1

3.) 2

4.) 6

Explanation :

The ratio of the measurement of the corresponding sides of a triangle is a scale factor .

When we multiply the side length by a scale factor >1 that gives a bigger scaled copy

When we multiply the side length by a scale factor <1 that gives a smaller scaled copy

From the given options , scale factor 1/2 is less than 1

So 1/2 is the scale factor that could use to make the triangle smaller

Answer:

[tex]5.3\times 10^{-11}\ m[/tex]

Step-by-step explanation:

In this problem, we need to express 53 pm in which is the size of a hydrogen atom, in scientific notation.

Any number can be expressed in scientific notation as follows :

[tex]N=a\times 10^b[/tex]

a is any real no and b is any integer

We know that, 1 pm = [tex]10^{-12}\ m[/tex]

It means, [tex]53\ pm=53\times 10^{-12}\ m[/tex]

or

[tex]53\times 10^{-12}\ m=\dfrac{53}{10}\times 10^{-12}\times 10\\\\=5.3\times 10^{-12+1}\\\\=5.3\times 10^{-11}\ m[/tex]

Therefore, the above is the scientific notation for the size of a hydrogen atom.

Answer:

Mean Absolute Deviation = 2.4

Step-by-step explanation:

Find you have to find the mean (average):

3 + 5 + 7 + 9 + 11 = 35

35 / 5 = 7

Mean = 7

The mean absolute deviation is the mean (average) of the distance from the other numbers (absolute means that if the number is negative it turns into a positive):

3 - 7 = 4

5 - 7 = 2

7 - 7 = 0

9 - 7 = 2

11 - 7 = 4

Now we have to find the mean of this numbers:

4 + 2 + 0 + 2 + 4 = 12

12 / 5 = 2.4

Mean Absolute Deviation = 2.4

Answer:

105.12 ft^2

Step-by-step explanation:

Area of rectangle = 8 × 10 = 80 ft^2

Area of semicircle = 1/2π × 4^2

4 is the radius of the semicircle.

Since we use 3.14 to approximate π...

Area of semicircle = 1/2× 3.14 × 4^2 = 25.12

∴Total area = 25.12 + 80 = 105.12 ft^2

Answer: 105.12ft²

Step-by-step explanation: first we need to find the area of the rectangle with the formula: length × width so, 8ft × 10ft = 80 ft².

Now we can find the area of the semicircle with the formula: πr²÷ 2 so, (3.14 × 4²) ÷ 2 = 25.12ft². Now we need to calculate the area of the whole shape and we can do this by adding together our rectangle and semicircle so, 80ft + 25.12ft = 105.12ft².

Step-by-step explanation:

A function is such that every element in the domain has only 1 image in the range. The domain here are the x-values while the range is the y-values.

However a vertical line can cross the graph more than once. Hence the graph is not a function.

Answer:

y-intercept: 2

x-intercept: -2, 4

Step-by-step explanation:

Y-intercepts and x-intercepts are points on the graph that are on the y-axis and x-axis, respectively.

Looking at the graph, the graph passes through the y-axis at y=2. Therefore, the y-intercept is 2.

Looking at the graph, the graph passes through the x-axis at x=-2 and x=4. Therefore, the x-intercepts are -2 and 4.

Answer:9/25

Step-by-step explanation:

Because .36=36/100. Then, divide by four for numerator and denominator

Answer:

9/25

Step-by-step explanation:

0.36 = 9

25

as a fraction

To convert the decimal 0.36 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

0.36 = 0.36

1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

0.36

1

= (0.36 × 100)

(1 × 100)

= 36

100

.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(36,100) = 4. So,

(36÷4)/(100÷4)

= 9

25

when reduced to the simplest form.

Step-by-step explanation:

You have to use pythagoras' theorem for this.

So AC is the length you want to find.

Pythagoras' theorem is a^2+b^2=c^2

In your triangle, AB=a, BC=b and AC=c

6^2+8^2=Ac^2

36+64= AC^2

100=AC^2

Square root both sides

10=AC

Therefore AC=10m

Take the L.C.M of 12 and 8

To find out the L.C.M , first of all find the prime factors of each numbers.

12 = 2 × 2 × 3

8 = 2 × 2 × 2

Take out the common prime factors : 2 and 2

Also, take out the remaining prime factors: 3 and 2

Multiply those all prime factors and obtain L.C.M

= 2 × 2 × 3 × 2 = 24

L.C.M. of 12 and 8 = 24

Answer: 252

Step-by-step explanation:

The amount of tax paid by Sarah last month is £252.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Sarah's gross income last month was £1260. She pays 20% tax on her gross income.

The tax amount is calculated by taking 20% of the gross income £1260.

Tax amount = 20% of £1260.

Tax amount = £1260 x 20 /100

Tax amount = £1260 / 5

Tax amount =£252.

Therefore, the amount of tax paid by Sarah last month is £252.

Answer:

75/7 = 105/7 (ten whole number, five over seven)

Step-by-step explanation:

1/3n + 25 = 2n

n is the number

n/3 + 25/1 = 2n

n + 75/3 = 2n

cross multiply

n + 75 = 6n

75 = 7n

n = 75/7

n = ten whole number, five over seven (105/7)

A = 4 × [tex]\frac{1}{2}[/tex] × 8 × 6 = 2 × 48 = 96 cm²

The number of students in the class = 20

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

30 percent of the students in your class like basketball.

We need to find the total number of students if 6 students like basketball.

Let there are 'x' students in the class.

⇒ x × 30% = 6

⇒ x × (30/100) = 6

⇒ x = 6/0.3

⇒ x = 20

Therefore, there are 20 students in the class.

Answer:

Because  a drop in temperature means decrease in temperature therefore, we take an integer  with negative sign and added to previous temperature.

Step-by-step explanation:

Drop in temperature means decrease in the temperature .When the temperature decreases then we take decrease value of temperature in negative integer. Because decrease means the temperature fall  down  .Hence , the  decrease in temperature measure with negative sign .

For example,  if we take temperature T= 70°C.

If the temperature decreases by 5°c  then the temperature

Decrease in temperature=-5°C

Hence, the temperature T= 70+(-5)=65°C.

Therefore , from example we can say that when temperature decreases by some value in integer . Then ,we get final  temperature obtained  by adding  drop in temperature ( negative integer  ) in previous value of the temperature.

Answer: Sample reasopnse

A drop in temperature means the temperature will decrease. That decrease is represented by a negative integer, which should be added to the previous temperature.
