Answers

Answer 1

Answer:

-14

Step-by-step explanation:

Given

AB=x + 25, AC=26, BC= 29 + x

As per segment addition postulate

AB + BC = AC

Substituting values

x + 25 + 29 + x = 262x = -28x = -14

Answers

Answer:

  √13

Step-by-step explanation:

There's a formula called the distance formula that is based on the Pythagorean theorem. It is used to find the distance between points in 2 (or more) dimensions.

The distance (d) between points (x1, y1) and (x2, y2) is ...

  d = √((x2-x1)^2 +(y2-y1)^2)

___

To find the distance you're looking for, fill in the values in the formula and do the arithmetic.

  d = √((6-3)^2 +(5-7)^2) = √(3^2 +(-2)^2)

  d = √(9 +4)

  d = √13

The distance between the given points is √13.

Answer:

y = -4y = -8

Step-by-step explanation:

For the first possible answer (y = -4):

Simplify: 6 + y = 2Subtract 6 from each side, so it now looks like this: y = -4

I don't know how to explain the second one, I'm sorry!

Answer:

y = -8

y = -4

Step-by-step explanation:

The equation |6 + y| = 2 can only be true when 6 + y = -2 and 6 + y = 2. This is because:

|-2| = 2

and

|2| = 2

First, lets find for what y values the equation 6 + y = -2 is true. Solve for y:

6 + y = -2

Subtract 6 from both sides.

y = -8

So now we have one of the values of y.

To find the second value of y, we must solve for y in the equation 6 + y = 2:

6 + y = 2

Subtract 6 from both sides.

y = -4

So the two values of y are -8 and -4.

A rectangle's perimeter and area have the same value. The width of the rectangle is 6 units. What is the length of the rectangle in units?

Answers

Answer:

The length ot rectangle is 3 units.

Step-by-step explanation:

The formula for perimeter is P = 2l + 2w and the area is A = l×w. Assuming that the perimeter and area have the same values so you have to compare it :

[tex]perimeter = 2l + 2w[/tex]

[tex]area= l \times w[/tex]

[tex]perimeter = area[/tex]

[tex]2l + 2w = lw[/tex]

[tex]let \: w = 6[/tex]

[tex]2l + 2(6) = 6l[/tex]

[tex]2l + 12 = 6l[/tex]

[tex]12 = 6l - 2l[/tex]

6. - Laura es piloto comercial. Cada semana realiza cinco viajes de ida y vuelta entre Santiago de Cali y Cartagena. La distancia entre ambas ciudades es de 782 Km. Laura estima que en seis semanas recorre más de 40.000 Km, que es como dar la vuelta al mundo. ¿Tiene razón Laura?

Answers

Distance between city , D = 782 km.

Number of trips in a week , n = 5.

Total distance covered in a week , d = D × n = 782 × 5 = 3910 km.

Now, distance covered in six weeks is :

[tex]D'=d\times 6\\\\D'=3910\times 6\ km\\\\D'=23460\ km[/tex]

Therefore, her assumption of travelling 40,000 km in six week is wrong.

Hence, this is the required solution.

Answer:

83

Step-by-step explanation:

The sum of the angles of a triangle is 180

x + 2x+1 + x+ 15 = 180

Combine like terms

4x+16 = 180

Subtract 16 from each side

4x+16-16 = 180-16

4x = 164

Divide by 4

4x/4 = 164/4

x = 41

The angles are

x=41

x+15 = 41+15 = 56

2x+1 = 2*41+1 = 82+1 = 83

The largest angle is 83

Answer:

Option (D) : 83

Step-by-step explanation:

We know that,

(2x + 1) + x + (x +15) = 180°

4x + 16 = 180°

X = 41°

Largest angle in triangle = 83

For every 1 litre of water used to make a medicine, 193ml of sucrose and 61ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Answers

Answer is the ratio 1000:193:61

Explanation

1 liter = 1000 mL

For every 1000 mL of water, we need 193 mL of sucrose and 61 mL of saline solution.

The ratio is therefore 1000:193:61

We cannot simplify this ratio any further because the GCF of those three terms is 1.

A quick way to see this is to look at how 1000 = (2*5)^3 has prime factors 2 and 5, but 2 nor 5 are factors of 193 and 61. So only 1 is a factor of all three values 1000, 193, 61

Mrs. Jones got a new freezer. She plugged it in, and it began to get cold. The
temperature inside the freezer dropped 24 degrees in 6 hours. If the temperature
dropped at a steady rate, what was the change in the temperature in the freezer in one

Answers

The rate of change for one hour is 4°.
When you look at the problem it says the temperature dropped 24° in 6 hours . So if you divided 24 by 6 you get 4 which is the rate at which the temperature dropped per hour.

Answers

Answer:

B.  41

Step-by-step explanation:

took the test and got it correct :)

The required measure of the angle BCA is 41°. Option B is correct.


Given,
ABCD is a parallelogram, where AC is the diagonal.
Angle ABC is 113°,  angle DCA is 26°, the measure of angle BCA is to be determined.

What is parallelogram?

A parallelogram is a quadrilateral consisting of pairs of parallel sides.

What is the triangle?

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Since angle DCA is 26°, angle CAB is also 26° because of an alternate interior angle of the parallelogram is equal.
So consider a triangle ABC, the sum of the interior angle of a triangle is 180,
∠CAB + ∠ABC + ∠BCA = 180°
26 + 113 + ∠BCA = 180
∠BCA  = 180 - 139
∠BCA  = 41°

Thus, the required measure of the angle BCA is 41°. Option B is correct.
