A 10 foot ladder is leaning against a house. The base of the ladder is 4 feet from the house. How far does the ladder reach up the house?

Answers

Answer 1

Answer:

9.17 feet

Step-by-step explanation:

Use the Pythogoras theorem, a^2 + b^2 = c^2

you are give c and b ( because one side is slanted, so c) so rearrange to get

c^2-b^2 = a^2

10^2 - 4^2 = 84

square root 84 to get

9.16515

The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?

Answers

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

[tex]P = 2(l + w)[/tex]

The side lengths of a rectangle are all multiplied by 5.

This means that [tex]l = 5l, w = 5w[/tex]. So

[tex]P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)[/tex]

What happens to its perimeter?

The rate is:

[tex]\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5[/tex]

The perimeter is multiplied by 5.

Answer:

Line A: y = 3x + 3

Line B: y = -1/3x + 3

Step-by-step explanation:

Line A points: (0, 3) and (1, 6)

Slope:

m=(y2-y1)/(x2-x1)

m=(6-3)/(1-0)

m= 3

y - y1 = m(x - x1)

y - 3 = 3(x - 0)

y - 3 = 3x

y = 3x + 3

Line B points: (0, 3) and (9, 0)

Slope:

m=(y2-y1)/(x2-x1)

m=(0-3)/(9-0)

m= -1/3

y - y1 = m(x - x1)

y - 3 = -1/3(x - 0)

y - 3 = -1/3x

y = -1/3x + 3

Pls answer its khan academy I really need it

Answers

Answer:

Step-by-step explanation:

Note the f(0) = 9

and f(1) = 15

Since, f(x) = abˣ substituting for x, we get:

9 = f(0) = a . b⁰ = a

⇒ a = 9

Now, f(1) = 15

⇒ 15 = a . b¹

⇒ 15 = 9 . b

⇒ b = 15/19

Therefore,

f (r) = 9. (5/3)

Hence, the answer.

SAT scores: The College Board reports that in 2009, the mean score on the math SAT was 582 and the population standard deviation was =σ120. A random sample of 20 students who took the test in 2010 had a mean score of 515. Following is a dotplot of the 20 scores. (a) Are the assumptions for a hypothesis test satisfied? Explain. (b) If appropriate, perform a hypothesis test to investigate whether the mean score in 2010 differs from the mean score in 2009. Assume the population standard deviation is =σ120. What can you conclude? Use the =α0.10 level of significance and the critical value method.

Answers

Answer:

we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.

Step-by-step explanation:

H0 : μ = 582

H1 : μ < 582

Test statistic :

T = (xbar - μ) ÷ σ/√n

Xbar = 515 ; n = 20 ; σ = 120

T = (515 - 582) ÷ 120/√20

T = -67 / 26.832815

T = 2.50

Pvalue at t score = 2.50 ; df = 19 is 0.0187

At α = 0.0187

Pvalue > α ; Hence, we fail to reject the Null

Hence, we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.

A cylinder has a radius of 5 m and a height of 11 m. Identify the volume of the cylinder to the nearest tenth.

Answers

Answer:

86,405 cm³

Step-by-step explanation:

V = cross-sectional area × height = πr²h = 3.142 × 5² × 1100cm

= 86,405 cm³

Answer:

863.9 m³

Step-by-step explanation:

Cylinder volume is V = πr²h.  Here the height, h, is 11 m and the radius, r, is 5 m.  Thus we have:

V = π(5 m)²(11 m), or

V = π(275) m³, or approximately 863.9 m³

Jana wants to buy a shirt at the store. The shirt is normally $24, but today it is on sale for 15% off.
How much will she save?

Answers

Answer:

She will save $3.60

Step-by-step explanation:

10% of 24= 2.4

5% of 24 = 1.2

2.4 + 1.2= 3.6

This means she is saving $3.60 because 15% of $24 is $3.60! :)

Jana save $3.6 to buy a shirt.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The shirt is normally $24, but today it is on sale for 15% off.

Now,

Since, The shirt is normally $24, but today it is on sale for 15% off.

Hence, The save money = 15% of 24

                                       = 15/100 × 24

                                       = $3.6

Thus, She save $3.6 on the shirt.
