6 x 6 = 36
100 - 36 = 64
square root of 64 is 8

14 ten thousands + 12 thousands

Doss [256]

Answer:
152,000

Explanation:
First, we will need to translate the words into numbers and then we will perform the addition.

1- translating the words into numbers:
ten thousands means 10,000
14 ten thousands means 14 * 10000 = 140000
thousands means 1000
12 thousands means 12000

2- Performing the addition:
14 ten thousands + 12 thousands
= 140000 + 12000
= 152000

Hope this helps :)

Solve the following quadratic equations by extracting square roots.Answer the questions that follow.

Vikentia [17]

Answer:

1. x=±4

2. t=±9

3. r=±10

4. x=±12

5. s=±5

Step-by-step explanation:

1. x^2 = 16

Taking square root on both sides

$\sqrt{x^2}=\sqrt{16}\\\sqrt{x^2}=\sqrt{(4)^2}\\$

x=±4

2. t^2=81

Taking square root on both sides

$\sqrt{t^2}=\sqrt{81}\\\sqrt{t^2}=\sqrt{(9)^2}$

t=±9

3. r^2-100=0

$r^{2}-100=0\\r^2 =100\\Taking\ Square\ root\ on\ both\ sides\\\sqrt{r^2}=\sqrt{100}\\\sqrt{r^2}=\sqrt{(10)^2}$

r=±10

4. x²-144=0

x²=144

Taking square root on both sides

$\sqrt{x^2}=\sqrt{144}\\\sqrt{x^2}=\sqrt{(12)^2}$

x=±12

5. 2s²=50

$\frac{2s^2}{2} =\frac{50}{2}\\s^2=25\\Taking\ Square\ root\ on\ both\ sides\\\sqrt{s^2}=\sqrt{25}\\\sqrt{s^2}=\sqrt{(5)^2}$

s=±5 ..

The data below show the number of games won by a football team in each of the last 15 seasons. What is a histogram that represen

Ganezh [65]

See the attached picture for the histogram. To accomplish this manually, we would have to find the minimum and maximum (1 to 18), decide on the bin size (I used 1 here), and list the frequency of each result. In this case:
1-2 wins - 2
3 wins - 1
4 wins - 2
6 wins - 1
7 wins - 1
8 wins - 1
12 wins - 1
13 wins - 1
15 wins - 2
16 wins - 1
18 wins - 1
Then these are plotted on the histogram.
