Answer:

Since the lines are parallel, the alternate interior angle to 35° is also 35°. Using the exterior angle theorem (exterior angle = sum of its remote interior angles) we can write:

x + 35 = 105

x = 70°

Answer:

28.4 cups

Step-by-step explanation:

If 5 people have a combined weight of 880 pounds, each person sould have a weight of 880/5 = 176 pounds.

Now, we can set up a proportion:

[tex]\frac{176}{50} =\frac{100}{x}[/tex]

Cross Multiply:

176x = 5000

x = 5000/176 = 28.4 cups

The required number of cups that each person has 5.6 cups per 100 pounds.

There are 50 cups of rice and group of 5 combined weight of 880 pounds. To determine how many cups each person should get per 100 pounds.

Fraction is defined as the number of composition constitute the whole.

average wait of people = 880/5 = 176 pounds
Each person can have cup beside the 100 pound weight = 50/5 = 10(max)

Number of cups per 100 pounds = 50/880*100

                                                       = 5.6 cups per 100 pound

Thus, the required number of cups that each person has 5.6 cups per 100 pounds.

Answer:

an = an-1 +4  

a1 = 14

Step-by-step explanation:

The recursive formula is

an = an-1 +d  where d is the common difference

a1 = initial term

a1 = 14

d = the difference between the terms

Take the second term and subtract the first term

18-4 = 4

That is the common difference

an = an-1 +4  

a1 = 14

If we will analyze this sequence, we will notice that:

So,

[tex]\boxed{\left \{ {{a_1=14} \atop {a_n=a_{n-1}+4}} \right.}[/tex]

Therefore, the correct option is letter C.

44.4 degrees

The triangles are similar.

Step-by-step explanation:

The measurements of missing angles are 44.4 each and the triangles are similar.

Two triangles are said to be similar if they have congruent corresponding angles and their corresponding sides are in equal ratios.

Given that, there are two triangles, ΔQSR and ΔTUV, where ∠Q and ∠U = 98° and ∠V and ∠R = 37.6°, we need to find the measurement of third angle in both and the relation between the triangles,

Using the angles sum property of a triangles,

∠Q + ∠S + ∠R = 180°

∠T + ∠U + ∠V = 180°

Therefore,

∠S = 180°-(37.6°+98°)

∠S = 44.4

Similarly,

∠T = 44.4

Since, all the corresponding angles are congruent therefore, the triangles are similar.

Hence the measurements of missing angles are 44.4 each and the triangles are similar.

Answer:

x = −2.24 and x = 2.24

Step-by-step explanation:

16x^2 − 80 = 0

Add 80 to each side

16x^2 =80

Divide each side by 16

x^2 = 80/16

x^2 =5

Take the square root of each side

x = ± sqrt(5)

x = ±2.236067977

Answer:

x = 2.24  OR   x = -2.24

Step-by-step explanation:

=> [tex]16x^2-80 = 0[/tex]

Adding 80 to both sides

=> [tex]16x^2 = 80[/tex]

Dividing both sides by 16

=> [tex]x^2 = 80/16\\x^2 = 5[/tex]

Taking sqrt on both sides

=> x = ±√5

=> x = ±2.24

Answer:

79

Step-by-step explanation:

If we square m + 1/m we get (m + 1/m)² = m² + 2 * (m * 1/m) + 1/m² = m² + 2 + 1/m². Since m + 1/m = 9, (m + 1/m)² = 81 so that means that m² + 1/m² = 81 - 2 = 79.

Answer:

79 is correct  

Answer:

x = 65

Step-by-step explanation:

interior angles = 180°

45° + (2x - 5)° = 180°

(2x - 5)° = 180° - 45°

(2x - 5)° = 135°

2x° = 135° - 5°

2x° = 130°

x° = 130° ÷ 2

x° = 65°

x = 65

-3 bills from first envelope (-30 dollars)

-2 bills from second envelope (-40 dollars)

-1 bill from third envelope (-50 dollars)

total least possible amount that can be taken out: 120

Step-by-step explanation:

Any other ways results in more than 120 being taken away. Need to have the least taken away from the 50 bill envelope because 50 is the largest bill. Take away the most from the 10 bill envelope because 10 is the smallest bill.

Answer:

$120

Step-by-step explanation:

So this question isn't hard either

We can cross out excess information and just find the main points.

a. 3 Envolopes containing 10 bills, 20 bills, and 50 bills

b. 1-3 bills are taken out of each envolope

c. It wants you to find the least possible amt. that could have been token out.

So since we want the least, we must take the smallest out of the largest

In order, 1 from 50 (largest)

2 from 20 (middle)

and 3 from 10 (smallest)

this leaves us the equation (1x50) + (2x20) + (3x10) => 50+40+30 => 120

Thus, we have our answer 120

Answer:

y=-6

Step-by-step explanation:

The line shown is a horizontal line via the y-axis and has the equation y=4. A parallel line to it is a line that doesn't pass it. It may even have the form y=a wherein a is the y-coordinate of its points. The point (-4,-6) is on the line so y=-6 is the line.

please mark me brainliest!

y=-6 is the  equation of the line that is parallel to the given line and passes through the point (-4,-6 )

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of the line passing through points ( -8, 4) and (8, 4)

m=4-4/8+8

=0

Slope is zero.

The slope of the parallel line will be also zero.

Now equation of line passing through (-4, -6) which is parallel.

Let us find y intercept

-6=-4(0)+b

-6=b

So the equation will be y=-6.

Answer:

53/66

Explanation:

We can use complementary counting to find the probability of picking the outcomes we don't want, and then subtracting that from the whole. The outcomes we don't want are PPPP and PPPN.

Probability of picking PPPP: 5/11 * 4/10 * 3/9 * 2/8 = 120/7920 = 1/66

Probability of picking PPPN: 5/11 * 4/10 * 3/9 * 6/8 = 360/7290 = 3/66

We can arrange PPPN in four different ways (PPPN, PPNP, PNPP, NPPP) so we need to multiply by 4, giving 12/66.

The total of these two probabilities is 13/66. Subtracting from 66/66, the answer is 53/66.

53/66 is the probability that after drawing four coins.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that a hat contains six nickels and five pennies

Drawn coins from the hat at random, without replacement.

We need to find the probability that after drawing four coins in which removed at most two pennies from the hat.

We use complementary counting to find the probability of picking the outcomes.

Probability of picking PPPP:

5/11 × 4/10 × 3/9 × 2/8

= 120/7920

= 1/66

Probability of picking PPPN:

5/11 × 4/10 × 3/9 × 6/8

= 360/7290

= 3/66

Four different ways of arranging PPPN is (PPPN, PPNP, PNPP, NPPP)

3/66×4= 12/66.

The total of these two probabilities is 13/66.

1-13/66

53/66

Hence, 53/66 is the probability that after drawing four coins.

5 needs to be postive.

Answer: D.

Step-by-step explanation:

The common difference between each y-value is 18.

80 - 62 = 18

62 - 44 = 18

44 - 26 = 18

The function stays the same for every interval of the x-values

(1, 26)

(2, 44)

(3, 62)

Since the increase in the y-value is the same with equal intervals of x-values, the function represents the linear function. Thus, option D is correct.

Function is the expression that defines the relationship between the independent and dependent variables.

Determine the difference between the consecutive y-values.

44-26=18

62-44=18

80-62=18

98-80=18

It can be observed that the difference in the consecutive y-values is same, which is, 18.

Since the increase in the y-value is same with equal interval of x-values, the function represents the linear function.
