Answer:

length = 115 cm

width = 108 cm

Step-by-step explanation:

The perimeter of a rectangular swimming pool is 446 centimeters

LEt L be the length of the pool

The width of the pool is 7 centimeters less than the length of the pool.

width = length - 7

W= L-7

Given perimeter = 446

Perimeter of rectangle = 2(length)+2(width)

446 = 2(L) + 2(W)                    we know W = L-7

446 = 2(L) + 2(L-7)    

446 = 2L + 2L - 14

Add 14 on both sides

460 = 4L

divide by 4 on both sides

L= 115

Length L= 115

Width W = L - 7 = 115 - 7= 108

Measure of angle A???
Rudik [331]

Answer:

A

Step-by-step explanation:

The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.

A property of equilateral triangles is the angles are congruent.

The sum of the 3 angles = 180°, hence the measure of each angle is

\frac{180}{3} = 60° → A

Solve i + j + t (3i - j) = -i + s (j)<br> In the context of Vector Equations of a Line
Oksana_A [137]

Answer:

r = i + j + (-2/3)(3i - j)

Step-by-step explanation:

Vector Equation of a line - r = a + kb ; where r is the resultant vector of adding vector a and vector b and k is a constant

if a = i + j ; b = t(3i - j) and r = -i +s(j)

for this to be true all the vector components must be equal

summing i 's

i + 3ti  = -i; then t = -2/3

j - tj = sj; then s = 1-t; substitue t; s=1+2/3 = 5/3

so r = i + j + (-2/3)(3i - j) which will symplify to -i + 5/3j

BRAINLIEST ANSWER TO FIRST ANSWERER <br><br> What is the value of x?
grigory [225]
It's really simple


if a+95=180 you solve for a

a+95=180
-95 -95
a=85

a triangle in total is 180 degrees


now that you know two of the angles find x is really easy

you add 60+85

you get 145

you then subtract 180-145

and get 35 as the answer


x=35

The color distribution of Skittles is the following: 10% blue, orange, and green each, 23.3333% yellow, red, and purple each. In
irina1246 [14]

Answer:

No

Step-by-step explanation:

Given that:

Percentage of blue, orange and green = 10%

Percentage of yellow, red and purple = 23.3333%

Number of skittles in bag by color :

Red = 137

Orange = 39

Yellow = 130

Green = 39

Blue = 43

Purple = 112

According to the color distribution :

Number of blue, orange and green should be the same and also number of yellow, red and purple skittles must be the same.

Total number of skittles :

(137 + 39 + 130 + 39 + 43 + 112) = 500

10% of the total = 0.1 * 500 = 50

Hence,

We should have 50 blue, orange and green skittles

23.33333% of total = 116.666 (about 117 skittles of yellow, red and purple color)

What the fact family for 4,6,10 I got b 10-6=4 10-4=6 4+6=10 6+4=10 what your answer​
tensa zangetsu [6.8K]

Answer:

B

Step-by-step explanation:

These numbers form an addition and subtraction, fact family.

4, 6, 10

Choose the fact family formed by these numbers.

A.

10 – 6 = 4

10 – 6 = 4

4 + 6 = 10

4 + 6 = 10

B.

10 – 6 = 4

10 – 4 = 6

4 + 6 = 10

6 + 4 = 10

C.

4 + 6 = 10

10 – 6 = 4

D.

6 + 4 = 10

10 – 4 = 6
