Answer:

not similar

Step-by-step explanation:

Triangle FGH has two sides that are equal GH and GF

Triangle UVW does not have two sides that are equal

They cannot be similar

Answer:

No

Step-by-step explanation:

No, because the sides on the two triangles are not congruent and the smaller triangle can't be multiplied by a number to equal the bigger triangle.

Answer:

-7 and 5

Step-by-step explanation:

To tell what the x intercepts are you set both (x+7) and (x-5) equal to zero and then subtract/ add it to zero and then you have the answer. So x+7=0 would be x=-7 and x-5=0 would be 5

Part A

The coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.

Part B

To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve it.

25 × 7.50 = $187.5.

0.20 × 300 = $60

Total: $187.50 + $60 = $247.50 + $40 = $287.50

Part C

If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.

Step-by-step explanation:

Score of 2 questions = 2 *5 = 10

He got 2 questions wrong. So, 50 - 10 = 40.

Camden's test score out of 50 =  [tex]\frac{40}{50}[/tex]

Score for x questions = x *5 = 5x

Camden's score if he got 'x' questions wrong = 50 - 5x

Answer:

[tex]\Large \boxed{\mathrm{weight \ increases}}[/tex]

Step-by-step explanation:

Taking the formula for weight:

[tex]\sf Weight = mass \cdot acceleration \ of \ gravity[/tex]

[tex]W=m \cdot g[/tex]

The mass will remain the same.

[tex]\upuparrows W=m \ \ \cdot \upuparrows g[/tex]

As the force of gravity increases, the weight increases.

[tex]\downdownarrows W=m \ \ \cdot \downdownarrows g[/tex]

As the force of gravity decreases, the weight decreases.

Answer:

56.15

Step-by-step explanation:

First, convert  [tex]6\frac{9}{20}[/tex]  lbs to a decimal. Multiply the main number (6) by the denominator (20) and then add that number to the numerator (9). The number you will get will be (6 x 20)+9 = 129. 129 is now the new numerator as an improper fraction so the improper fraction is now [tex]\frac{129}{20}[/tex].

Now make [tex]17\frac{17}{25}[/tex] lbs an improper fraction. It would be [tex]\frac{442}{25}[/tex].

Now subtract the amount of pork from the total amount of meat. [tex]\frac{442}{25}[/tex] - [tex]\frac{129}{20}[/tex] . Find a common denominator. I'm going to use 500, although there might be something less.

[tex]\frac{5615}{100}[/tex] is the result. Now you can either start dividing or simplify the fraction, which hopefully you already know how to do. 5615 ÷ 100 = 56.15

Answer:

Angle 9 = 65°

Step-by-step explanation:

Given:

Angle 7 = 65°

Angle 7 is alternate to Angle 9

Find:

Angle 9

Computation:

We know that

alternate interior angles are equal and angle 7 is alternate to angle 9

So,

Angle 7 = Angle 9

So,

Angle 9 = 65°

[tex]x + 2y = -1\\x=-2,0,3\\f(x)=y\\[/tex]

plug in each value of x in the function y:

[tex]-2+2y=-1\\2y=1\\y=\frac{1}{2}[/tex]

first point is [tex](-2, \frac{1}{2})[/tex]

so when x = -2, f(x) = 1/2

[tex]0+2y=-1\\2y=-1\\y=-\frac{1}{2}[/tex]

second point is [tex](0,-\frac{1}{2})[/tex]

so when x = 0, f(x) = -1/2

[tex]3+2y=-1\\2y=-4\\y=-2[/tex]

third point is [tex](3,-2)[/tex]

so when x = 3, f(x) = -2

Answer:

1.625 hours

Step-by-step explanation:

The equation is

d = rt  where d is distance  r is rate and t is time

65 = 40 *t

Divide each side by 40

65/40 = t

1.625 hours = time

Step-by-step explanation:

first i would combine like terms so 1/4a + 1/3a is equal to 7/12 then the equation would be 7/12a+8=22 simplify the isolate the variable so i think it A=24

Answer:

Hey there!

Step-by-step explanation:

Equation: 1/4a + 1/a + 8 = 22

(The answer is 24)

(You have to do 3 steps in order to solve this question! The steps are below!)

~1. First you have to simplify both sides of the equation.

=> (1/4a + 1/3a) + (8) = 22

=> 7/12a + 8 = 22

~2. Next, subtract 8 from both of the sides.

After you do that you will get, 14

7/12a=14

~3. Lastly, you just multiply both sides by 12/7.

(12/7) x (7/12a)

(12/7) x (14)

~Therefore, A would equal to 24.

A=24

Step-by-step explanation:

If you are doing for an hour for Gym B you would do .75 cents for ever 5 minutes of that hour.

60 minutes in an hour so

60/5=12

12*0.75=9.00

So both Gyms are the same.

Answer:

First, let's define our coordinates.

Let's call East as the positive x-axis and North as the positive y-axis.

Now the data that we have is:

Speed  = 4 mph

Time = 3 hours.

Then the total distance traveled is:

D = 4mph*3h = 12 miles.

We also know that the angle is S 35° E.

(from east, 35° to south)

So we can write this angle as -35°.

Then if we want to know the component in South and East, we can first think this in polar coordinates

(R, θ)

where R = 12 miles, and θ = -35°

Now with this, we have that:

X = R*cos(θ) = the displacement to the east.

Y = R*sin(θ) = the displacement to the north (then -Y is the displacement to the south).

Then we have:

X = 12mi*cos(-35°) = 9.83mi

Y = 12mi*sin(-35°) = - 6.89 mi.

Then:

The displacement to the East is X = 9.83 miles

The displacement to the South is -Y = 6.89 miles.

The magnitude of southern displacement of the hiker is 6.88 miles.

The magnitude of eastern displacement of the hiker is 9.83 miles.

The given parameters;

The resultant displacement of the hiker is calculated as follows;

D = vt

D = 4 mph x 3 h

D = 12 miles

The magnitude of southern displacement of the hiker is calculated as follows;

[tex]D_y = D \times sin(\theta)\\\\D_y = 12 \ miles \times sin(35)\\\\D_y = 6.88 \ miles[/tex]

The magnitude of eastern displacement of the hiker is calculated as follows;

[tex]D_x = D \times cos(35)\\\\D_x = 12 \ miles \times cos(35)\\\\D_x = 9.83 \ miles[/tex]

Tracy sent 12 texts

Step-by-step explanation:

hope this helps

Answer:

The answer is 12 texts.

Step-by-step explanation:

Ok, so I'm assuming that Tracy is the little sister.

Stacy's texts: s

Tracy's texts: t

46 = s + t

s = 2t + 10

Substitute 2t + 10 for s in the first equation.

46 = 2t + 10 + t

46 = 3t + 10

-10          -10

36 = 3t

36/3 = 12

x = -1

Step-by-step explanation:

4x + 5 = 3x + 4

      -5           -5

4x =    3x -1

-3x =   -3x

1x = -1

x = -1

Answer:

x=-1

Step-by-step explanation:

4x+5=3x+4

subtract 3x from both sides of the equation

4x+5=3x+4

-3x      -3x

x+5=4

subtract 5 from both sides of the equation

x+5=4

Step-by-step explanation:

Answer: An expression that would be equal to this one using addition would be 7 + (-11). There is also the option of -7 + 11. When you add a negative, it is the equivalent to subtracting, because you are adding a negative value to a positive value.

Answer:

We. can see there's a  black point at -3.7 and an arrow going to the left.

As the arrow goes to the left, it must be less than -3.7 or less than or equal to -3.7, now, we will need to see the colour of the point to know which it is.

As there is a black point, -3.7 is also contained in this range...

What does that mean? That means it will be less than or equal to -3.7

So we know the correct option is a) less than or equal to -3.7, what we could write as ([tex]-\infty,-3.7[/tex]].
