Answer:

It would take 1 more mile if he took route Street A and then Street B rather than just Street C.

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

We use the Pythagorean Theorem to find the length of Street C:

2² + 1.5² = c²

c = √6.25

c = 2.5

Now we find how much longer route A and B is compared to C:

3.5 - (2 + 1.5) = 3.5 - 2.5 = 1

What is the standard deviation of the data set given below? 2,6,7,10,10

Masja [62]

Average = (2 + 6 + 7 + 10 + 10)/5 = 35/5 = 7

x - mean, square.

2 - 7 = -5, -5² = 25

<span>6 - 7 = -1, -1² = 1
</span>
<span>7 - 7 = 0, 0² = 0
</span>
<span>10 - 7 = 3, 3² = 9
</span>
<span>10 - 7 = 3, 3² = 9
</span>
Sum of square = 25 + 1 + 0 + 9 + 9 = 44

Variance = 44/5 = 8.8

Standard deviation = √variance = √8.8 ≈ 2.966

In the diagram triangles ABE and ACD are similar.

jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q

Horace is riding his bike on a bike path. Horace's bike got a flat tire 3/4 of the way down the path and he had to stop. How far

mixas84 [53]

The distance travelled before developing a flat tire illustrates multiplication of fractions

Horace rode a distance of $\frac {9}{16} mile$ before having a flat tire

From the complete question, the length of the path is given as

$Length=\frac 34\ mile$

The fraction of distance (d) traveled before having a flat tire is:

$d=\frac 34$

So, the distance (D) travelled is:

$D=d \times Length$

This gives

$D= \frac 34 \times \frac 34\ mile$

Rewrite as:

$D= \frac {3 \times 3}{4 \times 4} mile$

$D= \frac {9}{16} mile$

Hence, Horace rode a distance of $\frac {9}{16} mile$

CAN SOMEONE HELP ME PLEASE ILL GIVE BRAINLEST..I need step to step equation thanks

Dmitrij [34]

Answer:

The required co-ordinate is (-2, -5).

Step-by-step explanation:

For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: $R_{y = k} = (x, 2k - y)$ .

Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:

$R_{y = 1} (-2, 7) = (-2, 2(1) - 7)$

= (-2, -5)

The reflected point is (-2, -5).
