First break Multiplier (17) into 1 ten and 7 ones as
17=10+7
Then Multiply 6 to both of the parts of 17 then add it,
6×17
=6(10+7)
=6×10+6×7 [Distributive property]

A ladder that has a length of 13 m leans against a wall with the base of the ladder 5 m away from the bottom of the wall. Use this information to find how high above the ground the ladder meets the wall

Answers

Answer:

did you find the answer ??

The required height of the wall where the ladder meets the wall is 12 m.

Given that,
A ladder that has a length of 13 m leans against a wall with the base of the ladder 5 m away from the bottom of the wall. Use this information to find how high above the ground the ladder meets the wall is to be determined.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,
Let the height be h,
Applying Pythagoras' theorem,
h = √[13²-5²]
h = √169-25
h = √144
h = 12

Thus, the required height of the wall where the ladder meets the wall is 12 m.

Suppose we want to test to see if a roulette wheel is balanced. The wheel is spun 100 time resulting in 58 red outcomes. Is this evidence that the roulette wheel is out of balance

Answers

Solution :

Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes

[tex]$ \hat p =\frac{58}{100}$[/tex]

[tex]$ \hat p$[/tex] = 0.58

So we have to test,

[tex]$H_0 : p = 0.5$[/tex]

V/S    [tex]$H_a: p \neq 0.5 $[/tex]

The test statistic is

[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]

[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]

  [tex]$=\frac{0.08}{0.05}$[/tex]

  = 1.600

P value using the z table is 0.110

So P value greater than 0.05

Therefore, there is no evidence that roulette wheel is out of balance.

DE bisects BC. If BC = 5x-3 and CE= 2x+25 find the value of x

Answers

Answer:

x = 53

Step-by-step explanation:

The entire line is BC, the line DE bisects the line BC, meaning it cut the line in half. So CE is half of BC, so the equation for CE has to be multiplied by 2. Therefore:

5x - 3 = (2x + 25)2

multiply

5x - 3 = 4x + 50

ad 3 to both sides

5x = 4x + 53

subtract 4x from both sides

x = 53

Input into the equation to check:

5x - 3 = (2x + 25)2

5(53) - 3 = (2(53) + 25)2

265 - 3 = (106 + 25)2

262 = (131)2

262 = 262, it's correct :)

Answer: C

Step-by-step explanation:

The missing side of the triangle is the hypotenuse. We are given the length for both legs. To find the midding leg, we need to use teh Pythagorean Theorem.

Pythagorean Theorem: a²+b²=c²

A and b are the legs, while c is the hypotenuse. We plug in the legs and solve for c.

2²+3.6²=c²           [exponent]

4+12.96=c²          [add]

16.96=c²              [square root both sides]

[tex]c=\sqrt{16.96}[/tex]

Now that we have found the hypotenuse, we know the answer is C.

Hello!

[tex]\large\boxed{\sqrt{16.96}cm}[/tex]

Use the Pythagorean theorem to solve for the missing side of the triangle:

a² + b² = c²

Plug in the given side lengths to solve for "c", or the Hypotenuse:

(2)² + (3.6)² = c²

4 + 12.96 = c²

16.96 = c²

Take the square root of both sides:

√16.96 = c

g = 6

Step-by-step explanation:

3g + 10 = 28 (Subtracted 2.2g on both sides)

3g = 18 (Subtracted 10 on both sides)

g = 6 (Divided 3 on both sides)

To check to make sure you are correct, simply substitute your answer for g:

5.2(6) + 10 = 2.2(6) + 28

31.2 + 10 = 13.2 + 28

41.2 = 41.2

You'll know you're correct if they both equal the same. In this case, the solution works.

Ms Patel purchased some pliers, wrenches, and chisel sets for her shop. She bought twice as many pliers that cost $17.50 each as wrenches that cost $21.50 each. She bought 3 fewer chisel sets than pliers. How many of each tool did Ms Patel buy if she paid a total of $141 and the price of each chisel set is $28?

Answers

Answer:

Ms Patel bought 4 pliers, 2 wrenches and 1 plier set.

Step-by-step explanation:First, make a ratio. For every 2 wrenches, she bought 4 pliers and 1 chisel set. This ratio would be written as (in pliers:wrenches:chisels)

        4:2:1

Then, multiply each of these numbers by their price, and add them together.

        PLIERS: 4 × 17.50 = $70

        WRENCHES: 2 × 21.50 = $43

        CHISEL SETS: 1 x 28 = $28

        TOTAL = $70 + $43 + $28 = $141

As this adds up to $141, this shows that she bought 4 pliers, 2 wrenches and 1 chisel set.

Mrs Patel purchased 2 wrenches, 4 pliers, and 1 chisel set for her shop.

What is an equation of the line that passes through the points (-3,-1) and

Answers

Answer:

y=1/3x

When x of the line is -3, y of the line must be -1.When x of the line is 6, y of the line must be 2. y=1/3x+b. b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (-3,-1) and (6,2).(-3,-1). y=mx+b or -1=1/3 × -3+b, or solving for b: b=-1-(1/3)(-3). b=0.b came out to be zero, so there is no "+b" term.
