What is the area of the following circle?
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.

Emily went to Kroger to buy some fruit. She needs a dozen apples and some bananas. A dozen organic apples costs $11.45 and each organic banana costs 1.05 a piece. Emily went to Trader Joe's to compare prices. At Trader Joe's a dozen apples costs $13.45 and each organic banana 97 cents a piece. Write an equation for how many bananas Emily would have to buy for Kroger and Trader Joe's to be the same cost. Use 'b' as the variable. Use the format of Kroger=Trader Joe's
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)
Parallelogram JKLM is shown.
Parallelogram JKLM is divided into 4 triangles by K M and J L which intersect at point R. Angle L M K is 72 degrees, angle K J L is 56 degrees, and angle J M K is 27 degrees.
If KR = x + 7, KM = 3x − 5, and JL = 4x − 10, what are the values of x and JR?
The measure of x and JR are 19 and 33 respectively
From the given parallelogram,
KM = 2KR
Given the following
KM = 3x - 5KR = x + 7Hence;
3x - 5 = 2(x+7)
3x - 5 = 2x + 14
3x - 2x = 14 + 5
x = 19
Similarly, JL = 2JR
JR = JL/2
JR = 4x-10/2
JR = 4(19)-10/2
JR = 66/2
JR = 33
Hence the measure of x and JR are 19 and 33 respectively

What are the one-sided limits around the discontinuity
shown in the graph?
The one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.
What is a discontinuous function?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.

How can an area model help you set
up an equation for a problem situation?
Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.
We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.
Step-by-step explanation:
For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

solve for x -1/2x + 1/3 > 3/5
Answer:
x > 8/15
Step-by-step explanation:
x -1/2x + 1/3 > 3/5
Combine like terms
2/2x - 1/2x +1/3 > 3/5
1/2x + 1/3 > 3/5
Subtract 1/3 from each side
1/2x + 1/3 -1/3 > 3/5 -1/3
1/2x > 3/5 -1/3
Get a common denominator
1/2x > 9/15 - 5/15
1/2x > 4/15
Multiply each side by 2
2 * 1/2x > 4/15 * 2
x > 8/15

shown. A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees. What is the value of x, rounded to the nearest degree? x ≈ ° 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?
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

In ΔQRS, the measure of ∠S=90°, QS = 11, SR = 60, and RQ = 61. What is the value of the sine of ∠Q to the nearest hundredth?
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

The function below shows the cost of a hamburger with different numbers of toppings (t). f(t) = 1.90 + 1.40t What is the y-intercept, and what does it mean?
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.

need a answer i got two different ones but dont understand
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

Step-by-step explanation:
Ok, so I think what you can do for part b. is pretty simple. You know that $820 is for 4 weeks of work. 820/4 = 205. So he gets $205 per week. If 820 = 100%, then 205*3 = 75%. So the answer would be he will recieve 75% of his usual pay, and that will be $615.

Muhammad is paid x dollars an hour. He received a 10% raise. Which expression can Michael use to calculate his new hourly wage?
Answer: 1.1x
Step-by-step explanation:
Muhammad is getting paid x dollars and receives a raise of 10% of those x dollars.
New hourly wage is therefore:
= x + (10% * x)
= x + 10%x
= x + 0.1x
= 1.1x
Write an equation in slope-intercept form for a line that passes through the point (1, 6) and
has a slope of 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).
