Step-by-step explanation:

10% off means she pays 90% of the original price. (100% - 10% = 90%)

62 x 0.90 = 55.80 the sale price of the dress is $55.80

Now add the tax by multiplying the sale price by 1 + tax rate:

55.80 x 1.0675 = 59.57

She paid $59.57

Answer:

Rate = 4%

Step-by-step explanation:

Simple interest = (principal × rate × time) / 100

Principal = $399.00

Rate = ?

Time = 2 years

Interest = $31.92

Simple interest = (principal × rate × time) / 100

31.92 = (399 * x * 2) / 100

31.92 = 798x / 100

Cross product

31.92 * 100 = 798x

3192 = 798x

x = 3192 / 798

x = 4%

Rate = 4%

11 1/4

Step-by-step explanation:

Multiply this by three, 3, 6, 9.

3/4, 1 2/4, 2 1/4.

2 + 9 = 11.

11= 1/4 = 11 1/4

Answer:

Max drank 11 1/4 cups of milk today.

Explanation:

Convert the mixed number (3 3/4) to a fraction.  

Then your equation becomes:

15/4 x 3/1 (since he tripled the cups of milk he drank you multiply by 3 which as a fraction is 3/1)

Next:

15/4 x 3/1= 11 1/4!

Answer:

Yes

Step-by-step explanation:

A triangle is a "right" triangle if its lengths fullfil the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

Here, a and b are the shorter "legs" of the triangle, adjacent to its right angle, while c is the "hypotenuse," the longest side and the one opposite the right angle.

If we call the 1.9 cm and 2.7 cm our legs, the sum of their squares is:

[tex]2.7^2+1.9^2=10.9[/tex] cm

While squaring our hypotenuse gives us

[tex]3.3^2=10.89[/tex] cm

The fact that we measured the triangle's side lengths to 1 decimal point of accuracy means that there's a little margin of error baked into the measurement. The two previous calculations are within 0.01 cm of each other, which is more than close enough, so we can say that yes, this could be a right triangle.

Answer:

18 minutes earlier

Step-by-step explanation:

Given

[tex]Distance =119km[/tex]

[tex]Speed\ 1 = 70km/h[/tex]

[tex]Speed\ 2 = 85km/h[/tex]

Required

Determine how much sooner if traveled at speed 2 instead of speed 1

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

Make Time the subject

[tex]Time= \frac{Distance}{Speed }[/tex]

For Speed 1

[tex]Time= \frac{119km}{70km/h}[/tex]

[tex]Time= 1.7hr[/tex]

For Speed 2

[tex]Time= \frac{119km}{85km/h}[/tex]

[tex]Time= 1.4hr[/tex]

Calculate the difference

[tex]Difference = 1.7hr - 1.4hr[/tex]

[tex]Difference = 0.3hr[/tex]

Convert to minutes

[tex]Difference = 0.3*60\ min[/tex]

[tex]Difference = 18\ min[/tex]

If traveled at 85km/h, the van will arrive 18 minutes earlier

C

Step-by-step explanation:

Hey There!

So if you didn't know in an isosceles trapezoid the non parallel sides are congruent

So given the base lengths and the perimeter we subtract the given length from the perimeter and divide that by 2

40-10=40

30-14=16

16/2=8

so the lengths of the non parallel sides would be 8 cm and 8 cm

Answer:

m = 2

Step-by-step explanation:

Using the slope formula, we can find the slope of two points:

        y2 - y1

m = --------------

        x2 - x1

The slope is the same thing as change in y over change in x. Now, plugging in the points (0, -2) and (3, 4):

       4 - (-2)       4 + 2     6

m = -----------  =  ------- = ------  =  2

        3 - 0            3         3

So the slope is 2.

Answer:

262 square feet

Step-by-step explanation:

The required expression model for the cost of the ramp is y = 2.20x.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let the area of the ramp be x and the cost to build the ramp be y,

According to the question,
The material Santiago will use to build the ramp costs $2.20 per square foot.

Total cost = 2.20 × area of the ramp

Substitute the variable in the above expression,

y = 2.20x

The above equation represents the equation model for the cost of ramp y for the x square foot area of the ramp.

Thus, the required expression model for the cost of the ramp is y = 2.20x.

Answer:

y = x - 3/5

Step-by-step explanation:

Slope = -1

y - y1 = m(x - x1)

y + 3/5 = -1(x - 0)

y + 3/5 = x

y = x - 3/5

hope this helps. if not, send me a message :)

The equation representing the cost c in dollars and different amounts of meat in pounds p, is c = 7p

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, A butcher displays the cost, in dollars, of different amounts of meat in the table shown.

Finding the unit price,

3 pounds = $21

1 pound = 21/3 = $7

Therefore, if c is cost and p is total pounds,

c = 7p

Hence, the equation representing the cost c in dollars and different amounts of meat in pounds p, is c = 7p

Triangle Angle Theorem

In any triangle, the sum of all angles equals 180

180 - 34 + 86

=  60

Answer:

a. 35 degrees

b. 145 degrees

Step-by-step explanation:

a. Since the two base angles of this triangle are congruent, we can conclude that the triangle is isosceles, which means that the two base angles and sides are congruent.

Now, knowing that information, we can subtract 110 from 180 (the sum of all interior angles in a triangle) and we get 70. But this isn't our answer. This is the sum of both base angles. Since the base angles are congruent, we can divide the 70 by 2 to get the measure of ONE base angle, which is 35 degrees.

b. There are two approaches to solve this problem. I have worked both out.

1) We can use the Exterior Angle Theorem, which states that the sum of the interior angles is equal to the exterior angle. We can add 110 to 35, so we get 145 degrees as the measure of <1.

2) The second approach is supplementary angles. Since we see that one of the base angles and <1 is on the same line, we can subtract 35 from 180 to find the measure of <1 to get 145 degrees.

Either way you use, you get the correct answer. Hope this helped!

Answer:

A

Step-by-step explanation:

We are given two functions:

[tex]\displaystyle f(x)=\frac{x-16}{x^2+6x-40}\text{ and } g(x)=\frac{1}{x+10}[/tex]

And we want to find:

[tex]f(x)+g(x)[/tex]

Thus:

[tex]\displaystyle =\frac{x-16}{x^2+6x-40}+\frac{1}{x+10}[/tex]

We can factor the denominator of the first term:

[tex]\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}[/tex]

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

[tex]\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}\Big(\frac{x-4}{x-4}\Big)[/tex]

Multiply:

[tex]\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{x-4}{(x+10)(x-4)}[/tex]

Combine:

[tex]\displaystyle =\frac{(x-16)+(x-4)}{(x+10)(x-4)}[/tex]

Simplify:

[tex]\displaystyle =\frac{2x-20}{(x+10)(x-4)}[/tex]

We can expand the denominator:

[tex]\displaystyle =\frac{2x-20}{x^2+6x-40}[/tex]

Therefore, our answer is A.
