Quadrilateral ABCD Is A Parallelogram. Determine The Measure Of Angle A A) 96B) 52C) 39D) 78

Answers

Answer 1

Answer:

[tex]\huge\boxed{\text{(A)}\ 96 \textdegree}[/tex]

Step-by-step explanation:

A parallelogram has two pairs of identical angles.

The identical angles will be directly opposite from each other.

This means that:

Angle C = Angle AAngle D = Angle B

Therefore, we can say that Angle A is 3x degrees and Angle B is x+52 degrees.

It's also important to note that all angles in a quadrilateral add up to 360°.

Since we know the measure of each angle, we can add up the expressions for each and find x.

[tex]3x + 3x + (x+52) + (x+52) = 360[/tex]

Let's simplify this equation.

[tex]6x+(x+52)+(x+52)=360[/tex] [tex]8x+104=360[/tex] [tex]8x=256[/tex] [tex]x=32[/tex]  

Now that we know the value of x, let's use it to find the measure of Angle A.

We already proved earlier that Angle C is equivalent to Angle A. Since we know the expression for Angle C (3x) it'll be the same for angle A.

[tex]3(32)=96[/tex]

So A is 96°

Hope this helped!

O one imaginary solution
O two real solutions
O one real solution

Answers

Step-by-step explanation:

the degree of a polynomial determines 1:1 the number of solutions.

a quadratic equation (degree 2) has 2 solutions.

the general solution is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = -4

b = -4

c = -1

so,

x = (4 ± sqrt((-4)² - 4×-4×-1))/(2×-4)

when we look at the square root

16 - 16

we see that it is 0.

the square root of 0 is 0, and there is no difference between -0 and +0.

so, we get only one (real) solution : 4/-8 = -1/2

but : formally, there are still 2 solutions (as this is a quadratic equation). they are just identical.

so, I am not sure what your teacher wants to see in this case as answer.

my answer would be 2 real identical solutions.

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. 'When the
rock is cut in half, what is the volume and density of each piece?

Answers

Answer:

Volume= 4 cm³

Density= 2 g/cm³

Step-by-step explanation:

We have the following data:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

A bagel costs $2.15 and cream cheese
costs $0.75. If you buy milk for $2.00, is
$5.00 enough to cover the cost of all
items? Explain.

Answers

Answer:

Yes

Step-by-step explanation:

You do have enough money because 2.15+0.75+2.00 is = to 4.90 and we know that 4.90 is less than 5.00

Yes, because the total cost would be $4.90. If you pay with a 5 dollars bill then you would have $0.10 left over after you have purchased all those items
$2.15 + $0.75 = $2.90
$2.90 + $2.00 = $4.90

The emergency brake cable in a truck parked on a steep hill breaks and the truck starts rolling down the hill. The distance in feet, d, that the truck rolls is represented by the function d=f(t)=0.5t2. Using this function, find out how far the truck will roll after 9 seconds.

Answers

Answer:

The truck will roll 40.5 feet from top of the hill after 9 seconds.

Step-by-step explanation:

Let be [tex]f(t)[/tex] the distance rolled by the truck in time, measured in feet, whose expression is:

[tex]f(t) = 0.5\cdot t^{2}[/tex]

Where [tex]t[/tex] is the time, measured in seconds.

By evaluating this function at [tex]t = 9\,s[/tex], we find the distance rolled by the truck:

[tex]f(9\,s) = 0.5\cdot (9\,s)^{2}[/tex]

[tex]f(9\,s) = 40.5\,ft[/tex]

The truck will roll 40.5 feet from top of the hill after 9 seconds.

Answer:

Given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector)

Step-by-step explanation:

The given information are;

m∠ABC = m∠CBD

To prove that Ray BC bisects m∠ABD

The description is therefore;

Three lines (AB, BC, and BD) that meet at a point

The content of Box A = m∠ABC = m∠CBD

The content of Box B = m∠ABC ≅ m∠CBD

The content of Box C = Ray BC bisects  m∠ABD

Therefore, we have;

m∠ABD = m∠ABC + m∠CBD (Angle addition postulate)

m∠ABC = m∠CBD (Given)

∴ m∠ABC ≅ m∠CBD (Definition of congruent angles)

m∠ABC is adjacent to m∠CBD (Description of the angles)

Line BC is common to m∠ABC and m∠CBD (Description of the angles)

Therefore, given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector).

What is the median of the following dataset? (1,5,6,3,4,5,6,8,9)

Answers

Answer:

The median would be the second 5

Therefore our answer would be 5

Step-by-step explanation:

The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory

Solve each system by substitution. Show all work.
-8x+2y= -4
-7x+y= -8

Answers

Answer:

(2, 6 )

Step-by-step explanation:

- 8x + 2y = - 4 → (1)

- 7x + y = - 8 ( add 7x to both sides )

y = 7x - 8 → (2)

substitute y = 7x - 8 into (1)

- 8x + 2(7x - 8) = - 4 ← distribute parenthesis and simplify left side

- 8x + 14x - 16 = - 4

6x - 16 = - 4 ( add 16 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

substitute x ;= 2 into (2)

y = 7(2) - 8 = 14 - 8 = 6

solution is (2, 6 )
