Answer:

x= .5 (not 100% sure but I think that's right)

Step-by-step explanation:

2x = 1

x= .5

Answer:

x=1.5

Step-by-step explanation:

5x + 2 = 3x + 3

subtract 2 from both sides

5x + 2 - 2 = 3x + 3 - 2

simplify

5x = 3x + 1

subtract 3x from both sides

5x - 3x = 3x + 1 - 3x

2x = 1

divide both sides by 2

[tex]\frac{2x}{2}[/tex]=[tex]\frac{1}{2}[/tex]

simplify

x=[tex]\frac{1}{2}[/tex]

[tex]\frac{1}{2}[/tex]/1.5

sorry for the lengthy explanation hope this helps :) have a nice day !!

Answer:

0.98

Step-by-step explanation:

Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).

Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.

Sin(angle Q) = 60/61 = 0.98

Answer:

Infinite Solutions

Step-by-step explanation:

3(5x - 4) needs to be simplified

So we multiply 5x by 3

So 3 x 5x = 15x

Then we multiply -4 by 3

3 x -4 = - 12

Put those together we get 15x - 12

The same equation as the one on the right side

So since 15x - 12 = 15x - 12, the x variable can be any number

Answer:

Part A

71°

Part B

The ladder is been used safely

Step-by-step explanation:

Part A

We solve the above question using Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

Adjacent = The distance between the house and the bottom of the ladder = 4 feet

Hypotenuse = Length of the ladder = 12 feet

x = Angle

Hence:

cos x = 4/12

cos x = 1/3

x = arc cos (1/3)

x = 70.528779366°

Approximately to the nearest degree

= 71°

Part B

According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?

Angle x = 71°

Therefore, the ladder is been used safely

Answer:

1.05(b) = 0.97(b)

Step-by-step explanation:

What you know from the problem:

Krogers:

11.45(12)+1.05(b)

Trader Joe's:

13.45(12)+0.97(b)

Kroger = Trader Joe's

1.05(b) = 0.97(b)

Answer:

78.53

Step-by-step explanation:

[tex]\pi[/tex] x [tex]5^{2}[/tex]

Answer:

78.5

Step-by-step explanation:

The formula for the area of a circle is A=πr^2.  The radius, (r) is half of the diameter.  The diameter of this circle is 10 in, so the radius is 5 in.  Plug 5 into the formula A=πr^2 to get A=π5^2.  Square 5 to get 25 and plug it back in the formula to have A=25π.  Multiply pi (π, 3.14) by 25 to get 78.5.  

The number that is less than 1.25 is 1.2.

The given number is a decimal.  A decimal is a number that is made up of a whole number and fractional parts divided by a point. For example in 1.25, 1 is the whole number and 2 and 5 are the fractional parts.

The number that is greater than 1.25 would have either its tenth value greater than 2 or its hundredth value greater than 5. The number less than 1.25 would have either its tenth value less than 2 or its hundredth value less than 5.

Answer:

[tex]1.9[/tex]

the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Step-by-step explanation:

The function is

[tex]f(t)=1.9+1.4t[/tex]

Let cost of toppings be [tex]y[/tex]

[tex]y=1.9+1.4t[/tex]

The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].

So, the intercept of the function is [tex]1.9[/tex]

This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Answer: slope is 1/2 Distance is √ 5 or 2.236

Step-by-step explanation:

slope -

(0,1);(2,2)

(x1,y1)=(0,1)

(x2,y2)=(2,2)

Use the slope formula:

m= y2−y1/ x2−x1

= 2−1 /2−0

= 1 /2

Answer:

2.24%

Step-by-step explanation:

Given that :

Actual height = 68.5

Measured height = 67

Percentage error :

(Error value / True value) * 100%

Error = Actual - observed = (68.5 - 67) = 1.5

Percentage error :

(1.5 / 67) * 100%

0.0223880 * 100%

= 2.2388%

= 2.24%

Answer:

51/110

Step-by-step explanation:

No: of bags with buttons but no zips  = 46

No: of bags that have both buttons and zipz = 110-(46+20+39)  =  5

No: of bags with buttons = 46+ 5 = 51

Total no: of bags = 110

Probabilty = 51/110

The one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Discontinuous functions are functions that do not have a continuous curve - there is a hole or jump in the graph.

In the shown graph of the function, the function is discontinuous at x=-3

[tex]\lim_{x \to \ -3} g(x)[/tex] tends to infinity so [tex]\lim_{x \to \ -3} g(x)[/tex] does not exist.

[tex]\lim_{x \to \ +3} g(x)=0[/tex]

Hence, the one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Answer:

y=2x+4

Step-by-step explanation:

If the line has a slope of two, that means it goes up 2 on the y axis for every 1 on the x axis. So, if it goes through (1,6), then you can subtract 1 from the x axis and two from the y axis to find the y intercept, (0,4).
