Step-by-step explanation:

3x - 161 = 7x - 382

Balance method:

7x- 3x = -161 + 382

4x = 221

Divide to find x:

Answer:

In a quadrilateral ABCD, ∠A = 100°, ∠B = 105° and ∠C = 70°, find ∠D.

Solution:

Here the sum of the four angles

or, ∠A + ∠B + ∠C + ∠D = 360°

We know, ∠A = 100°, ∠B = 105° and ∠C = 70°

or, 100° + 105° + 70° + ∠D = 360°

or, 275° + ∠D = 360°

∠D = 360° - 275°

Therefore,  = 85°

Answer:

the probability that at least one of the girls (Piper and Sedona) get to go to the show is 0.533

Step-by-step explanation:

The computation of the probability that have at least one of the girl get to go is shown below;

[tex]= \frac{^2C_1 \times ^4C_1}{^6C_2} \\\\= \frac{8}{15}\\\\= 0.53333[/tex]

Hence, the probability that at least one of the girls (Piper and Sedona) get to go to the show is 0.533

So the same is relevant

Probability that at least one of the girls (Piper and Sedona) get to go to the show = 1/5

The number of grandchildren = 6

The number of girls = 2

Two grandkids out of 6 are to be selected

Number of ways of choosing 2 grandkids out of 6 is 6C2

[tex]6C2=\frac{6!}{(6-2)!2!} \\\\6C2=\frac{6!}{4! \times 2!} \\\\6C2 = 15[/tex]

Number of ways of selecting 2 grandkids out of 6 = 15 ways

Number of ways  of selecting 1 out of the two girls =2C1

[tex]2C1= 2[/tex]

Number of ways of selecting 1 out of the two girls = 2 ways

Number of ways of selecting of selecting both girls =2C2

Number of ways of selecting of selecting both girls = 1 way

Probability of selecting 1 out of the two grandkids = 1/15

Probability of selecting both girls = 2/15

Probability that at least one of the girls (Piper and Sedona) get to go to the show = 1/15 + 2/15

probability that at least one of the girls (Piper and Sedona) get to go to the show = 3/15

Probability that at least one of the girls (Piper and Sedona) get to go to the show = 1/5

Step-by-step explanation:

the point where both touch = the solution

The sum of magnitude of two vectors is 2√5.

A vector is a number or phenomena with two distinct properties: magnitude and direction. The term can also refer to a quantity's mathematical or geometrical representation. In nature, vectors include velocity, momentum, force, electromagnetic fields, and weight.

We have,

the magnitude of two vectors are 4 and 2.

and, The direction of two vectors are 45° and 135°.

According to vector addition,

The angle between both the vectors = 135 - 45 = 90

and, Sum of Vector

= √4² + 2²

= √16 + 4

= √20

Thus, the sum of magnitude of two vectors is 2√5.

Answer:

None of the expressions in the option is equal to 10 x(13).

Step-by-step explanation:

The answer can be verified by calculating the values of the expression in the question, those of each options, and then compare as follows:

Value of the expression = 10 x (13) = 10 x 13 = 130

Therefore, we have:

A. 10 + (1+3) = 10 + 4 = 14 [tex]\neq[/tex] 130

B. (10 x 1)+3 = 10 + 3 = 13 [tex]\neq[/tex] 130

C. 10 + (1x3) = 10 + 3 = 13 [tex]\neq[/tex] 130

D. (10 * 1)3 = 10 * 3 = 30 [tex]\neq[/tex] 130

Based on the calculations above, none of the expressions in the option is equal to 10 x(13).

Answer:

[tex]Gallons = 27.95[/tex]

Step-by-step explanation:

Given

[tex]Gallons : Miles = 17:590[/tex]

Required

Determine the number of gallon for 870 miles

To do this, we simply substitute 870 for miles in the ratio above

So, we have:

[tex]Gallons : 870= 17:590[/tex]

Convert to fraction

[tex]\frac{Gallons}{870} = \frac{17}{590}[/tex]

Multiply through  by 870

[tex]870 * \frac{Gallons}{870} = \frac{17}{590}*870[/tex]

[tex]Gallons = \frac{17}{590}*970[/tex]

[tex]Gallons = \frac{17*970}{590}[/tex]

[tex]Gallons = \frac{16490}{590}[/tex]

[tex]Gallons = 27.95[/tex]

The area is the volume divided by the height.

Area = 182 / 2.8

Area = 65 square meters

Area of the classroom floor is equals to [tex]65m^{2}[/tex].

" Area is defined as the total space occupied by any two dimensional object."

Formula used

Volume of a cuboid = Length × width × height

Area of a classroom floor = length × width

According to the question,

Given,

Height of a classroom = [tex]2.8m[/tex]

Volume of a classroom =[tex]182 m^{3}[/tex]

Substitute the value in the formula of volume we get,

182 = Length × width × 2.8

⇒Length × width = [tex]\frac{182}{2.8}[/tex]

⇒Length × width =[tex]65m^{2}[/tex]

Therefore,

Area of the classroom floor =[tex]65m^{2}[/tex]

Hence, area of the classroom floor is equals to [tex]65m^{2}[/tex].
