Find distance (4,7) (-4,-3)

AURORKA [14]

∆x = (4--4)=8

∆y = (7--3)= 10

Step-by-step explanation:

distance is given by;

d² = (∆y)²+ (∆x)²

d = √((∆y)²+ (∆x)²)

d = √((4+4)² + (7+3)²)

d = √((8²) + (10²))

d = √(64+100)

d = √164

d =12.806 units

Help me please ! Thank you so so much :)

#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side

#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS

Write the integers that are closest to the the number in the middle to complete the statement.

ArbitrLikvidat [17]

Answer:

see explanation

Step-by-step explanation:

Consider perfect squares on either side of 73, that is

64 < 73 < 81 , then

$\sqrt{64}$ < $\sqrt{73}$ < $\sqrt{81}$ , that is

8 < $\sqrt{73}$ < 9

You want to install a 2 yd wide walk around a circular swimming pool. The diameter of the pool is 23 yd. What is the area of the

GrogVix [38]

Answer:

157 square yards.

Step-by-step explanation:

Given:

Width of walk around a circular swimming pool = 2 yard

The diameter of the pool = 23 yard

Question asked:

What is the area of the walk ?

Solution:

To find area of walk, we will first calculate area of the pool and then combined area of pool and walk then after we will subtract the area of pool from combined area.

The diameter of the pool = 23 yard

Radius of the pool = $\frac{diameter }{2}=\frac{23}{2} =11.5\ yard$

$Area\ of\ circle=\pi r^{2}$

$=3.14\times(11.5)^{2} \\=3.14\times11.5\times11.5=415.265\ square\ yard$

As width of walk around a circular swimming pool is 2 yard :

New radius will be = 11.5 + 2 = 13.5 yard

$Combined\ area =\pi r^{2} \\$

$=3.14\times13.5\times13.5=572.265\ square\ yard$

Now, area of the walk = Combined area of pool and walk - Area of the pool

= 572.265 - 415.265

= 157 square yards

Therefore, area of the walk is 157 square yards.

To me, it looks like you got everything right, but one serving of grapefruit has 41 mg more vitamin c per serving than the tomato juice.

here’s my work.

Tomato: 247.5 / 5.5 = 45

Grapefruit: 258 / 3 = 86

86 - 45 = 41.
