Answers

Answer 1

Answer:

Triangle area = 20.91 cm^2

Step-by-step explanation:

area = 1/2(b*h)

area = 1/2(8.2*5.1)

area = 1/2(41.82)

area = 20.91 cm^2

x = 12angle A = 35angle ABC = 65

============================================================

Explanation:

Let y be the measure of angle ABC.

We can see that y = 4x+17 because the two angles (y and 4x+17) are vertical angles. Vertical angles are always congruent.

-------------

From here, focus entirely on the interior angles of triangle ABC.

Recall that for any triangle, the interior angles always add to 180

A+B+C = 180

(x+23)+(y)+(80) = 180 ..... plug in the given angle measures

(x+23)+(4x+17)+(80) = 180 .... replace y with 4x+17

5x+120 = 180 ..... combine like terms

5x = 180-120 ..... subtract 120 from both sides

5x = 60

x = 60/5 ..... divide both sides by 5

x = 12

Now use that x value to find the following:

angle A = x+23 = 12+23 = 35angle ABC = y = 4x+17 = 4*12+17 = 48+17 = 65

--------------------------

In short we have this summary of values we found:

x = 12angle A = 35angle ABC = 65
X=12
Angle A=35
And angle ABC=65

5. Write the polynomial in standard form. Then name the polynomial based on its degree and
number of terms.
5x + 2x4 – 4
O 5x – 4 + 2x4, not a polynomial
O 2x4 + 5x – 4; fourth-degree trinomial
O 5x + 2x4 – 4; quadratic monomial
O 2x4 + 5x – 4; cubic binomial

Answers

Answer:

Option (2)

Step-by-step explanation:

Standard form of the polynomial will be in the form of (ax⁴+ bx³+ cx²+ dx + e).

Which means exponents of each successive term will be in the reducing form and the last term will be a constant term.

Now we can rearrange the terms of the given polynomial (5x + 2x⁴ - 4) for the standard form.

(2x⁴ + 5x - 4)

Since, degree of the leading term = 4

And number of terms = 3

Given polynomial is a fourth degree trinomial.

Option (2) will be the answer.

What is the image of (-8,- 7) after a dilation by a scale factor of 2 centered
at the origin?

Answers

Answer:   (-16, -14)

==========================================================

Explanation:

To get that result, you multiply each coordinate by the scale factor 2

We have

-8*2 = -16-7*2 = -14

So that's why (-8,-7) moves to (-16, -14)

This trick only works if the origin is the center of dilation.

You and your friend are standing back-to-back. Your friend runs 10 feet forward and then 8 feet right. At the same time, you run 11 feet forward and then 12 feet right. You stop and throw a baseball to your friend, who catches it. How far did you throw the baseball?

Answers

Answer:

29 feet

Imagine you are on an open plane.

you walk 11 feet forward and your friend 10 feet. you are now 21 feet apart. now put imaginary walls that stopped both of you at that 21 feet.

now, you go 12 feet to your right, and your friend 8 feet to their right. imagine you are pushing a wall in front of you.

at that point the side walls are 20 feet apart.

you and your friend are at opposite corners of a 20 by 21 foot room.

at that point it's just a matter if applying the Pythagorium theory.

Answer:

Carlita is correct because Dot Plot A is more spread out than Dot Pot B

Step-by-step explanation:

Dot Plot B is skewed left which means most of its data is on the left side so it will mostly have lower numbers as data. On the other hand, Dot Plot A is spread out so it has both low numbers but also some higher numbers.

Davie and Horatio are riding their motorbikes on a scenic tour that is 80 miles long. Davie rides at 20 miles per hour and leaves 90 minutes before Horatio. How fast must Horatio ride to finish at the same time as Davie?
24 mph
24.5 mph
32 mph
33.3 mph

Answers

He would need to go 32 mph because if David is 1 hour and 30 min ahead he would be 30 miles in and would need 50 and that would be 2 and a half hours therefore leading Horatio needing to go 32 miles an hour for them to finish at the same time

The speed Horatio ride to finish at the same time as Davie is mathematically given as

X=32 mph

What is the speed Horatio ride to finish at the same time as Davie?

Question Parameter(s):

Davie and Horatio are riding their motorbikes on a scenic tour that is 80 miles long.

Davie rides at 20 miles per hour and leaves 90 minutes before

If two lines are parallel, then
corresponding angles are congruent. i

Answers

Answer: Choice B)

If corresponding angles are not congruent, then the lines are not parallel.

==================================================

Explanation:

The given conditional is in the form "If P, then Q"

where,

P = two lines are parallelQ = corresponding angles are congruent

The P and Q are placeholders for those definitions shown above. So we'll simply do a "search and replace" to replace P and Q with those phrases. We do this shortening so that we can do logical operations.

Specifically, we'll do two things:

Swap the positions of P and QPlace a "not" before each letter after the swap

We go from the format "if P, then Q" to "if not Q, then not P". Those two formats are equivalent in truth value. This is known as the contrapositive.

In terms of the problem at hand, the phrase "if not Q, then not P" becomes "If corresponding angles are not congruent, then the lines are not parallel"

-------------

In short, we swap each part of the original "if ..., then ..." statement, and stick "not"s in there to negate each piece.

Option B is correct, if corresponding angles are not congruent then the lines are not parallel.

What is Mathematical Reasoning?

In mathematics, reasoning involves drawing logical conclusions based on evidence or stated assumptions

The given statement is "If two lines are parallel, then corresponding angles are congruent."

Let us consider p as two lines are parallel,

q as corresponding angles are congruent.

If p is true then q should be true

or else if p is false then q also should be false

if P, then Q" to "if not Q, then not P". Those two formats are equivalent in truth value

This is known as the contrapositive.

"If two lines are parallel, then corresponding angles are congruent." is equivalent to if corresponding angles are not congruent then the lines are not parallel.

Hence, option B is correct, if corresponding angles are not congruent then the lines are not parallel.

What is the area of the circle?

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The four small circles are identical. The total area of the small circles is 36π square inches. Then the radius of each small circle is given as,

36π = 4 × (πr²)

r² = 9

r = 3 inches

Then the radius of the larger circle is calculated as,

R = 4r

R = 4 × 3

R = 12

Then the area of the larger circle will be given as,

A = π × (12)²

A = 144π square inches

The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.

Putting [tex]x=2x+1[/tex], we get

[tex]h(2x+1)=(2x)^2+2(2x)(1)+(1)^2-3(2x)-3(1)+5[/tex]

[tex]h(2x+1)=4x^2+4x+1-6x-3+5[/tex]
