Can someone please help with the answer!!! Thank you :)

Answer:

x=-4 is the answer

Step-by-step explanation:

-7x+9=3x+49

Subtracting 3x on both sides

-7x-3x+9=49

Subtracting 9 on both sides

-10x=49-9

-10x=40

x=-4

I hope this will help you :)

Answer:

B

Step-by-step explanation:

Both A and B are similar but the difference is that muckrakers did not present facts to encourage more investigation, they presented facts to make a change. There are many examples but one major one is Upton Sinclair and his book "The Jungle". It exposed the meat industry and how corrupted it was. This led to many changes such as new food safety laws.

Step-by-step explanation:

Answer:  8.94 is the length of GI

Step-by-step explanation: The two triangles are similar, so the ratios of the sides to each other will be the same.

the unknown length of GI in triangle FIG corresponds to the known length 20 of IH in Triangle GIH, and the known length 4 of side FI in triangle FIG corresponds to GI in Triangle GIH. So the ratio looks like 4:x as x:20

4/x = x/20  multiply both sides by x and 20 to "cancel" the denominators.

20x(4/x) = 20x(x/20)

80 = x²    Calculate the square roots  

√x² = x . √80 = 8.94

Answer:

Third choice is correct

Step-by-step explanation:

-2x-y=-2

-y=2x-2

y=-2x+2

3x-y=-2

-y=-3x-2

y=3x+2

These two lines intersect at (0, 2)

Answer: The distance is 17.

Step-by-step explanation:

Find their difference in the y values and the difference in the x values then find their absolute values.

2-17 = -15

-6 - 2 = -8  

The absolute value of -15 is 15 and the absolute value of  -8 is 8.

Now square them and add them up to find their square root.

15^2 + 8^2 = c^2

225 + 64 = c^2

289= c^2

c=  17

Answer:

The answer is "Option A"

Step-by-step explanation:

Given:

[tex]\to \frac{(a-5)+a}{2}=x.....(a)\\\\\to \frac{a+(a+9)}{2}=y.....(b)\\\\[/tex]

solve the above equation:

[tex]\to \bold{\frac{(a-5)+a}{2}=x}\\\\\to \frac{a-5+a}{2}=x\\\\\to \frac{2a-5}{2}=x\\\\\to \bold{\frac{a+(a+9)}{2}=y}\\\\\to \frac{a+a+9}{2}=y\\\\\to \frac{2a+9}{2}=y\\\\[/tex]

add both value (x and y):

[tex]\to \bold{x+y}\\\\\to \frac{2a-5}{2}+\frac{2a+9}{2}\\\\\to \frac{2a-5+2a+9}{2}\\\\\to \frac{4a+4}{2}\\\\\to \frac{2(2a+2)}{2}\\\\\to (2a+2)\\[/tex]

average of x and y:

[tex]\to \frac{x+y}{2}\\\\\therefore \bold{x+y= 2a+2}\\\\\to \frac{2(a+1)}{2}\\\\\to \boxed{(a+1)}\\[/tex]

Answer:

12 in²

Step-by-step explanation:

The area of a triangle is base × height × 1/2.

b × h × 1/2

6 × 4 × 1/2

24 × 1/2

= 12

The area is 12 in².

Answer:

Solution,

Base(b)=6 inches

Height(h)=4 inches

Area of triangle=?

Now,

[tex]area \: of \: triangle \\ = \frac{bh}{2} \\ = \frac{6 \times 4}{2} \\ = \frac{24}{2} \\ = 12 \: {inches}^{2} [/tex]

Step-by-step explanation:

f(x) = 7x^4 + 3x^2 - 4

f(-2) = 7(-2)^4 + 3(-2)^2 - 4 = 7(16) + 3(4) - 4 = 112 + 12 - 4 = 120

Answer:

Step-by-step explanation:

Given,

Plug the value of x

[tex] = 7 \times {( - 2)}^{4} + 3 \times {( - 2)}^{2} - 4[/tex]

A negative base raised to an even power equals a positive

[tex] = 7 \times {2}^{4} + 3 \times {2}^{2} - 4[/tex]

Answers:

length of rope = 2 meters

perimeter of meadow = 12.56 square meters

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

Explanation:

Assuming there are no structures (buildings, fences, etc) to get in the way of the goat, this means the goat's area that it can roam is a circle with radius r

The area of the circle is pi*r^2 which is equal to 12.56 square meters

pi*r^2 = 12.56

3.14*r^2 = 12.56

r^2 = 4

r = sqrt(4)

r = 2

The radius of the circle is 2 meters. This is the length of the rope. If the goat goes out as far as it can go, and tries to move left/right, then it will trace out a circle of radius 2. This is assuming the rope is kept fully taut the entire time.

The perimeter of the circle is the same as the circumference

circumference = 2*pi*r

circumference = 2*pi*2

circumference = 4*pi

circumference = 4*3.14

circumference = 12.56

The circumference and area are the same because r^2 = 4 and 2*r = 4 when r = 2. For any other positive r value, the area and circumference will be different values.

So in short, if a friend says that the area of a circle is the same as its perimeter, then you can immediately conclude the radius is 2.

Side note: throughout all of this solution, I used the approximation pi = 3.14 though pi has more decimal digits

Answer:

Each gets 36 nights of sleep every 45 nights.

Step-by-step explanation:

This is called the handshake problem, which is the same problem as n guests (including host) attend a party.  At the end, everyone shakes hands with everyone else.  The number of handshakes is each person shakes hands with (n-1) other persons to give n(n-1) handshakes.  However, this counts each handshake twice (A with B and B with A), so the actual number of handshakes is n(n-1)/2

For n=10, then number of "teams" of two meerkats is 10(10-1)/2 = 45.  

So each meerkat gets to be on duty 9 nights out of 45, or gets 36 nights of sleep every 45 nights.

Good luck on your assignment..

Step-by-step explanation:

This question requires the Pythagorean theorem.

Car A travels north 100km in two hours.

Car B travels west 160km in two hours.

Imagine a triangle the line going up is 100km

the line going left is 160km

the formula for the Pythagorean theorem is

a^2+b^2=c^2

100^2+160^2=c^2

10000+25600=c

35600=c

Answer:

using SOHCAHTOA

COS THETA WILL BE EQUALS TO ROOT 5/3 AND TAN THETA WILL BE EQUALS TO 2ROOT 5/3

Answer:

B.

Step-by-step explanation:

First, note that since [tex]sin(\theta)=2/3[/tex], this means that the opposite side is 2, the hypotenuse is 3, and the last, adjacent side is [tex]\sqrt{5\\[/tex].

Also note that we are told that [tex]sec(\theta)<0[/tex]. This means that [tex]\theta[/tex] cannot be in quadrants 1 nor 4 because (remember All Students Take Calculus?) in those quadrants cosine and secant are positive. Also, we know that sine is positive so we can conclude that [tex]\theta[/tex] is in the second quadrant.

In the second quadrant, sine is positive, cosine is negative, and tangent is negative. Now we can answer the question. We already know the side lengths: opposite=2, adjacent=[tex]-\sqrt{5}[/tex] (because it's in Quadrant II), and hypotenuse=3.

Therefore...

[tex]cos(\theta)=-\sqrt{5} /3[/tex]

[tex]tan(\theta)=2/(-\sqrt{5})=-(2\sqrt{5}/5)[/tex]

Answer: [tex]1.6\pi[/tex]

Step-by-step explanation:

If a circle has a radius of 6, then the perimeter of the circle is 12pi, or about 37.68.  A circle has 360 degrees.  Thus, the arc takes up 48/360 of the circle.  Thus, simply multiply [tex]\frac{48}{360} * 12\pi[/tex] to get 5.024 or 1.6pi.

Question:

Found a picture which relates to the question asked. It can be found in the attachment below.

Answer:

b. c2 + b2 = a2

Step-by-step explanation:

According to Pythagoras rule :

The longest side of the triangle is the hypotenus

The opposite and adjacent sides depends on the particular angle provided or one which is to be calculated.

The opposite side is one drawn across a given angle, while the side next to the Given angle is called the adjacent side.

FROM △ABC ;

THE longest side is 'a' = hypotenus

Opposite side = c

Adjacent = b

From Pythagoras :

(Hypotenus)^2 = (Opposite)^2 + (adjacent)^2

Hence,

a^2 = c^2 + b^2

Answer:

The result is 0.36b

Step-by-step explanation:

Here. we want to translate the wordings into an expression of algebra.

Firstly, we decrease b by 40%

40% is same as 40/100 = 0.4

So decreasing b by 40% = b-0.4(b) = b-0.4b = 0.6b

Now we want to decrease 0.6b by another 40%

= 0.6b -0.4(0.6b)

= 0.6b - 0.24b

= 0.36b
