Answer 1

Answer: CB = 7. AC = 5.

Step-by-step explanation:

Well we know that A-B is 7. And this is a right triangle, so the CB will be the same length. So CB = 7.

Now AC.

You divide 45 degrees by 7. And you get five.

So AC = 5 and CB = 7.

Answer 2

Answer:

AC= 7√6/2

CB=7√2/2

Answer:

f(x)= -2|x-3|-1

(Hi Jasmine! I just wanted to help you with this question but I might be wrong)

Step-by-step explanation:

f(x) = a|x-h|+k

f(x)= a|x-3|-1

-7 = a |0-3| -1

-7 = a |-3| -1 <-- add to -7

-6 = a |-3|

-6 = 3a

-6/3 = a

-2 = a

---------------------------------- -------------------------------------------------

The equation of the absolute value is f(x)= -2|x-3|-1

Simplify this expression: -2x + 3 – (5 – 6x). Can someone pls explain how to do this dont just give the awnser

Answers

Answer:

-2x + 3 – (5 – 6x) = 4x - 2

Step-by-step explanation:

The given expression is :

-2x + 3 – (5 – 6x)

We need to simplify the above expression. First opening the brackets.

-2x + 3 – (5 – 6x) = -2x + 3 – 5 + 6x

Taking like terms together,

= -2x+6x + 3 -5

= 4x - 2

So, the simplified expression is 4x - 2.

Teacher chooses to students in a class of 15 girls and 10 boys the students are randomly choosing what is the probability that the teacher chooses to girls

Answers

Answer:

7/20

Step-by-step explanation:

So first we know that there are a total od 25 students

15+10=25

And the probability of choosing the first girl is 15/25 or 3/5 simpler terms.

Now to be able to choose another girl in a row just multiply the then probability

So we started off with 25, if a girl was choosen, the population would b 24

and with 24, there is a missing girl so instead of 15 it is 14

now 14/24 or 7/12 simplified

multiply the two

7/12*3/5=21/60

Answer:

The simplified expression of [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] is 7² ⇒ C

Step-by-step explanation:

Let us revise some rules of exponent

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{m+n}[/tex][tex]\frac{a^{m}}{a^{n}}[/tex] = [tex]a^{m-n}[/tex]

Let us solve the question

∵ The expression is [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex]

→ By using the first rule above add the exponents of 7

∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]\frac{7^{4+6}}{7^{8}}[/tex]

∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]\frac{7^{10}}{7^{8}}[/tex]

→ By using the second rule above, subtract the exponents of 7

∵ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]7^{10-8}[/tex]

∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = 7²

∴ The simplified expression of [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] is 7²

the answer is 7 power 2

Rachel participated in a 12-kilometer walkathon to raise money for her favorite charity. If it took her 2.5 hours to complete it, what was the rate in kilometers per hour?

Answers

Step-by-step explanation:

here they gave 12 km are reached by 2.5 hours so we. should how much time they took for 1km

12/ 2.5 which is also 150min

12km which is also 12000

12000/150= 80m

it took 80m in 1min so

1hr = 60min

1hr x 80m

60x80

4800

convert it intlo km

4800/1000

4.8km

so it took 4.8 km for 1hour

The time to complete the race is 2.5 hours, then the rate will be equal to 4.8 kilometers per hour.

What are arithmetic operations?

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

Total distance = 12 kilometers

Total time taken to complete 12 kilometers = 2.5 hours

Then, the rate in kilometers per hour will be,

= 12/2.5

= 4.8 kilometers per hour.
