Answers

Answer 1
3.1 cups of white four and 4.5 cups of whole wheat flour adding it together 3.1n (standing for the white flour) and 4.5n (standing for the whole wheat flour) is 7.6n times .50 is $3.80  So the answer is C.
 

Hope this helps :)
Answer 2

By converting mixed numbers to decimals and multiplying the total number of cups of flour by the cost per cup, we find out Maria will spend $3.80 on flour, which is option C.

To find out how much Maria will spend on flour to make her cookies, we need to calculate the total cost of white and whole wheat flour. Maria needs 3 1/10 cups of white flour and 4 1/2 cups of whole wheat flour. First, we convert the mixed numbers to decimal form: 3 1/10 cups is 3.1 cups, and 4 1/2 cups is 4.5 cups. Then we add them together to find the total number of cups Maria will use:

3.1 cups + 4.5 cups = 7.6 cups

Next, since flour costs $0.50 per cup, we multiply the total number of cups by the cost per cup:

7.6 cups × $0.50 per cup = $3.80

Therefore, Maria will spend a total of $3.80 on flour for her cookie recipe, making the correct answer C. $3.80.

Answer:

The number of spots in the parking lot if there are 32 parking spots in the first row =111.

Step-by-step explanation:

We are given that a new parking lot is being built for a medical office.

We are given that

The expression representing the number of parking spots in the new lot =[tex]\frac{15x}{4}-9[/tex]

Where x= The number of parking lots in the first row

We have to find number of spots in the parking lot when parking spots in the first row is 32.

The number of parking spots in the first row =x=32

Substitute the value of x in the given expression then we get

Number of spots in the parking lot =[tex]\frac{15\times 32}{4}-9[/tex]

Number of spots in the parking lot=[tex]\frac{480}{4}-9[/tex]

The number of spots in the parking lot=120-9

The number of spots in the parking lot=111.

Hence, the number of spots in the parking lot if there are 32 parking spots in the first row=111.

A line passes through the point (2, 3) and has a slope of -2. Which is the equation of the line in point-slope form?

Answers

The equation of the line would be y=-2x+9

The correct answer is option B: [tex]\( y = -2x + 7 \).[/tex] To write the equation of a line passing through the point (2, 3) with a slope of -2, we can use the point-slope form of a linear equation.

The point-slope form is given as:

[tex]\[ y - y_1 = m(x - x_1) \][/tex]

Where [tex]\( (x_1, y_1) \)[/tex] is a point on the line and [tex]\( m \)[/tex] is the slope.

Given that the point is [tex]\( (2, 3) \)[/tex] and the slope is [tex]\( -2 \)[/tex], we can substitute these values into the point-slope form:

[tex]\[ y - 3 = -2(x - 2) \][/tex]

Now, we can simplify and rewrite the equation in various forms to match the options provided:

Option A: [tex]\( 2x + y = 7 \)[/tex]

To match this option, let's rearrange the equation:

[tex]\[ y - 3 = -2(x - 2) \][/tex]

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

[tex]\[ 2x + y = 7 \][/tex]

So, option A is equivalent to the given equation.

Option B: [tex]\( y = -2x + 7 \)[/tex]

Let's solve the equation for [tex]\( y \):[/tex]

[tex]\[ y - 3 = -2(x - 2) \][/tex]

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

[tex]\[ y = -2x + 7 \][/tex]

This matches option B.

Option C: [tex]\( y - 3 = -2(x - 2) \)[/tex]

This is already in point-slope form and matches the given equation.

Option D: [tex]\( y = -\frac{1}{2} x + 5 \)[/tex]

Let's solve the equation for [tex]\( y \):[/tex]

[tex]\[ y - 3 = -2(x - 2) \][/tex]

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

[tex]\[ y = -2x + 7 \][/tex]

This does not match option D.

Therefore, the correct answer is option B: [tex]\( y = -2x + 7 \).[/tex]

The complete question is:

A line passes through the point (2, 3) and has a slope of -2. Which is the equation of the line in point-slope form?

Find the area of the triangle. (round to the nearest whole number)

Answers

Answer: 210 square inches

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

Explanation:

Check out the attached image. I've added in points A through D. The points A,B,C are the vertices of the largest triangle. Point D is directly below point A, and point D is on segment BC. 

To find the area of the largest triangle ABC, we need the base length BC, which is broken up into segments x and y

x = length from C to D
y = length from D to B

Let's find x first

Triangle ADC is a right triangle, so we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2 + 15^2 = 17^2
x^2 + 225 = 289
x^2 = 289 - 225
x^2 = 64
x = sqrt(64)
x = 8

Follow similar steps to find y
a^2 + b^2 = c^2
y^2 + 15^2 = 25^2
y^2 + 225 = 625
y^2 = 625 - 225
y^2 = 400
y = sqrt(400)
y = 20

Therefore
BC = x+y
BC = 8+20
BC = 28

The base of the triangle ABC is BC = 28 units
b = base
b = 28

The height is AD = 15
h = height
h = 15

We can now find the area of triangle ABC
Area = b*h/2
Area = 28*15/2
Area = 420/2
Area = 210

The area of the triangle is 210 square inches

There are four red bicycle helmets in a bin. If a helmet is selected without looking, what is the probability that the helmet is red?

A 1/4
B 1/3
C 4/4
D 3/4

Answers

C - 4/4 It is pretty simple because there are no other colors so there is a 100% chance that red will be it's color. 4/4 = 100%

Final answer:

Given that all helmets in the bin are red, the probability of randomly selecting a red helmet is 1, which corresponds to answer C.

Explanation:

The question is asking for the probability that a randomly selected helmet from a bin of four is red. Since all the helmets in the bin are red, no matter which one you pick, it will be red. In probability, this is represented as the total number of favorable outcomes divided by the total number of outcomes. In this scenario, both favorable outcomes (red helmets) and total outcomes (helmets in the bin) are four. Mathematically, 4/4 results in 1. So, the correct answer is C which symbolize the probability to be 1.

What are the solutions of the equation x^2 - 7x -8= 0? Complete the square.

Answers

Use the formula (b/ 2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x = 8 , − 1

the solutions to the equation [tex]\( x^2 - 7x - 8 = 0 \)[/tex] are ( x = 8 ) and ( x = -1 ).

To solve the quadratic equation[tex]\( x^2 - 7x - 8 = 0 \)[/tex]by completing the square, we follow these steps:

1. Move the constant term to the other side of the equation:

[tex]\[ x^2 - 7x = 8 \][/tex]

2. To complete the square, take half of the coefficient of ( x ) (which is -7), square it, and add it to both sides of the equation:

[tex]\[ x^2 - 7x + \left( \frac{-7}{2} \right)^2 = 8 + \left( \frac{-7}{2} \right)^2 \]\[ x^2 - 7x + \frac{49}{4} = 8 + \frac{49}{4} \][/tex]

3. Simplify the right side of the equation:

[tex]\[ x^2 - 7x + \frac{49}{4} = \frac{32}{4} + \frac{49}{4} \]\[ x^2 - 7x + \frac{49}{4} = \frac{81}{4} \][/tex]

4. Write the left side of the equation as a perfect square:

[tex]\[ \left( x - \frac{7}{2} \right)^2 = \frac{81}{4} \][/tex]

5. Take the square root of both sides to solve for ( x ):

[tex]\[ x - \frac{7}{2} = \pm \sqrt{\frac{81}{4}} \]\[ x - \frac{7}{2} = \pm \frac{9}{2} \][/tex]

6. Solve for ( x ) by adding [tex]\( \frac{7}{2} \)[/tex]to both sides:

[tex]\[ x = \frac{7}{2} \pm \frac{9}{2} \][/tex]

This gives us two solutions:

[tex]\[ x = \frac{7}{2} + \frac{9}{2} = \frac{16}{2} = 8 \]\[ x = \frac{7}{2} - \frac{9}{2} = \frac{-2}{2} = -1 \][/tex]

So, the solutions to the equation [tex]\( x^2 - 7x - 8 = 0 \)[/tex] are ( x = 8 ) and ( x = -1 ).

Answers

11) Since the triangle has a pair of congruent base angles, it is an isosceles triangle which means that the two pairs of legs are congruent.

Make them equal to each other in an equation.

5x = x + 20

Subtract x from both sides.

4x = 20

Divide both sides by 4.

x = 5

12) The two legs are congruent so that means the base angles must be congruent. First find the measure of the base angles. Create an equation:

x + x + 50 = 180

Combine like terms.

2x + 50 = 180

Subtract 50 from both sides.

2x = 130

Divide both sides by 2.

x = 65

Now make the base angle plus x equal 180, because they form a straight line.

65 + x = 180

Subtract 65 from both sides.

x = 115

13) You know the vertex angle (top angle) is 90 degrees because it is supplementary to a right angle. The triangle is isosceles because the two legs are congruent, so make the base angles plus 90 add up to 180 in an equation.

x + x + 90 = 180

Combine like terms.

2x + 90 = 180

Subtract 90 from both sides.

2x = 90

Divide both sides by 2.

x = 45
