Answer:

x-intercept = 3 ; y-intercept = -5

Step-by-step explanation:

Lets rearrange the equation into the form y = mx + b:

5x - 3y = 15

-3y = 15 - 5x

Divide by -3:

y = 5x/3 - 5

Here we know that b (-5) is the y-intercept, and we can find the x-intercept by starting at the y-intercept and using the slope till we get the x-intercept. Or you can set y = 0 and solve for x, either way you get x-intercept = 3.

This equation is in standard form, if you put it into slope-intercept form, you will be able to graph it. Once you graph it you will be able to find the intercepts.

5x - 3y = 15

-3y = -5x + 15

y = 5/3x - 5

Answer:

Height is 18 inches.

Base is 36 inches.

Step-by-step explanation:

Let the base of the triangular table top be x inches.

The height will be [tex]\frac{1}{2}[/tex]x inches.

The area of the triangular table top is 324 inches²

Area of a triangle = [tex]\frac{1}{2}[/tex] × Base × Height

342 inches² = [tex]\frac{1}{2}[/tex] × x × [tex]\frac{1}{2}[/tex]x

[tex]\frac{x^2}{4}[/tex] = 324

Finding the square root on both sides gives;

[tex]\frac{x}{2}[/tex] = 18

Therefore x (the base) = 36 inches

And [tex]\frac{1}{2}[/tex] (the height) = 18 inches.

Final answer:

The height of the triangular table top is 18 inches, and the base is 36 inches, using the formula for the area of a triangle and given that the base is twice the height with an area of 324 square inches.

Explanation:

The question requires finding the height and base of a triangular table top given that the area is 324 square inches and the base is twice as long as the height. To find these dimensions, we can use the formula for the area of a triangle, which is Area (A) = [tex]\frac{1}{2}[/tex] × base (b) × height (h). Given that the base is twice the height, we can express the base as 2h.

Now, we can set up the equation using the given area: 324 = [tex]\frac{1}{2}[/tex] × 2h × h. Simplifying gives us 324 = h², so the height (h) would be the square root of 324, which is 18 inches. The base (2h) is therefore 36 inches. So, the dimensions of the tabletop are a base of 36 inches and a height of 18 inches.

The Apex Savings Bank was required to keep a reserve of 4.5% of the deposit. The bank was free to loan out the remaining 95.5% which equaled $12,128.50.

The reserve rate is the percentage of the deposit that the bank must keep, in this case, Apex Savings Bank. To calculate the reserve rate, we divide the reserve by the deposit and multiply by 100%. Therefore, ($571.50 / $12,700) * 100% = 4.5%. This means the bank had a reserve rate of 4.5% at that time.

Moving on towards the second question about how much Apex Savings Bank was free to loan out. Since the bank must keep 4.5% of the deposit, it is free to loan out the rest, which is 100% - 4.5% = 95.5%. By applying this percentage to the deposit, we see that Apex Savings Bank was free to loan out 95.5% of $12,700, or $12,128.50.

Answer:

b≤15

Step-by-step explanation:

If he only has 15 birdhouses in stock, then he can only sell 15 or less birdhouses. He cant sell more birdhouses, simply because he doesnt have more than 15.

Final answer:

The inequality representing the number of birdhouses Jason can sell, given he has 15, is b≤15 since he cannot sell more than he has.

Explanation:

The inequality that represents the number of birdhouses, b, Jason can sell at a craft fair, given he has 15 birdhouses, is b≤15. This is because the number of birdhouses he can sell cannot exceed the number he has, which is 15. The inequality b≤15 means that Jason can sell no more than 15 birdhouses, he could sell exactly 15, or he could sell less, depending on the demand at the craft fair.

This constraint ensures that Jason operates within the bounds of his available stock, preventing him from overselling. It implies that Jason can sell up to 15 birdhouses, including the possibility of selling exactly 15 or selling fewer, depending on the demand at the craft fair. This inequality serves as a practical guideline for Jason to manage his sales effectively, aligning his offerings with the limitations of his inventory.

Answer:

The total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair is $3.

Step-by-step explanation:

Let us assume that the cost of the one hot dogs be x.

Let us assume that the cost of the one ice cream cone be y.

Let us assume that the cost of the one silce of pizza be z.

As given

At the county fair, two hot dogs and an ice cream cone cost $2.50.

Than the equation becomes

2x + y = 2.50

Two slices of pizza and an ice cream cone cost $3.50.

2z + y = 3.50

Than two equations are

2x + y = 2.50 and 2z + y = 3.50

Adding the both above equation.

2x + y +  2z + y = 2.50 + 3.50

2x + 2z + 2y = 6

[tex]x + y + z = \frac{6}{2}[/tex]

x + y + z = 3

Therefore the total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair is $3.

An exponent represents repeated multiplication. For example, ...

... x^3 = x·x·x

... x^2 = x·x

If we divide these, the x's in the denominator cancel an equal number in the numerator:

... (x·x·x)/(x·x) = x

If we represent the repeated multiplication using exponents, we can represent the cancellation by subtraction:

... (x^3)/(x^2) = x^(3-2) = x^1 = x

Once we have this idea in mind that division can be done by subtracting denominator exponents, we can use it regardless of the magnitude or sign of the exponents involved.

Answer: ∠ A = ∠B= 48° and ∠ C = 84°

Step-by-step explanation:

Here, m∠ADE: m∠ADB = 2:9

Let m∠ADE = 2x and m∠ADB = 9x

Where x is any value.

By joining the points D and E (construction)

Since, Here DE ║ AB.

⇒ ∠DAB = 2 x

⇒ ∠ A = 4x ( because AD is the angle bisector so, ∠DAB=∠DAE = 2x )

Now,  Let O is the intersection point of angle bisectors AD and BE.

Then, By the property of angle bisctor.

O is the circumcenter of the triangle ABC.

Therefore, OA = OB

⇒ ∠DAB = ∠EBA = 2 x

But BE is the angle bisceor,

Therefore, ∠EBA = ∠EBC=2 x

But, ∠B = ∠EBA + ∠EBC

⇒ ∠B = 4x

Now, since BD is the same transversal on the parallel lines AB and ED,

⇒ ∠B = ∠ EDC

⇒ ∠ EDC = 4x

Since, ∠ADB + ∠ADE + ∠EDC = 180°

⇒ 9x + 2x + 4x = 180°

⇒ 15x = 180°

⇒ x = 12°

Thus, the measures of the angles of ΔABC are,

∠ A = 4x =4×12 = 48°

∠ B = 4x =4×12= 48°

⇒ ∠ C = 180° - 48°- 48°= 84°

The question is about finding the angles of a triangle given certain conditions. We use the Angle Bisector Theorem and other geometric principles related to angle bisectors. We set up an equation based on these principles and solve for the angles.

The given scenario is about triangle ABC, with AD and BE acting as angle bisectors of ∠A and ∠B respectively. Also, provided is the ratio of m∠ADE to m∠ADB, which is 2/9. Given these conditions, we are to find the measures of the angles of ΔABC.

First, we can make use of the Angle Bisector Theorem, which states that an angle bisector of an angle of a triangle divides the opposite side in a ratio equal to the ratio of the other two sides. From this theorem, we see that m∠ADE / m∠ADB = AD / DB.

We know from the given that m∠ADE/m∠ADB = 2/9.

Since DE is parallel to AB, angle ∠ADE is equal to angle ∠BAC and angle ∠ADB is equal to angle ∠ABC by the corresponding angles postulate.

As ∠ADE and ∠ADB are part of a straight angle ∠ADA, then ∠ABC + ∠BAC = 180° - ∠ADB. We can use these relationships to create an equation, solve for the angles, and find the measures of the angles of ΔABC.

The lengths of the sides of triangle DEF are DE = 0.75 cm, EF = 1.125 cm, and DF = 1.5 cm.

Triangles ABC and DEF are similar, which means their corresponding angles are equal. In similar triangles, the ratio of the lengths of corresponding sides is constant. To find the lengths of the sides of DEF, we can use the ratio of the corresponding sides of ABC and DEF.

Let x be the length of DE in triangle DEF. Since DE corresponds to AB, we have the ratio x/2 = 1.5/4, which simplifies to x = 0.75 cm. Similarly, for EF corresponding to BC, y/3 = 1.5/4, giving y = 1.125 cm. Finally, for DF corresponding to CA, z/4 = 1.5/4, yielding z = 1.5 cm.

Therefore, the lengths of the sides of triangle DEF are DE = 0.75 cm, EF = 1.125 cm, and DF = 1.5 cm. This result is consistent with the idea that in similar triangles, the ratio of corresponding sides remains constant.

The calculation involved setting up and solving simple proportions based on the given lengths of the sides of triangle ABC and using them to find the lengths of the sides of triangle DEF.

[tex]tan(A) = \frac{10}{36}[/tex]

To find A we move tan to the other side, it becomes tan^-1

Answer:

3 adults and 24 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 27 tickets were purchased, then s+a=27.

We also know they were purchased for $60 and adult tickets cost $4 and student tickets cost $2. We can write 2s+4a=60.

We will solve by substituting one equation into the other. We start by solving the first equation for c. s+a=27 becomes s=27-a.

Now we substitute s=27-a into 2s+4a=60. Simplify and isolate the variable a.

2s+4a=60

2(27-a)+4a=60

54-2a+4a=60

54+2a=60

54-54+2a=60-54

2a=6

a=3

This means that 3 adults attended and 24 students attended since 3+24=27.
