X:y = 7:4

x:y= 88

Work out the value of x-y

Answer:

12

Step-by-step explanation:

Mary worked for 30 hours. This is calculated by first determining how many lamps Mia assembled, then subtracting this from the total to find out how many lamps Mary assembled. Finally, we divide the number of lamps assembled by Mary by her rate to find out how many hours she worked.

The question requires us to find out how many hours Mary worked if we know that together, Mary and Mia assembled 600 lamps, Mary assembles 10 lamps per hour, Mia assembles 12 lamps per hour, and Mia worked for 25 hours.

First, we can determine how many lamps Mia assembled by multiplying her working hours by her rate, resulting in 300 lamps (12 lamps per hour * 25 hours).

Next, we subtract the number of lamps assembled by Mia from the total to find how many lamps Mary assembled, resulting in 300 lamps (600 lamps total - 300 lamps assembled by Mia).

Finally, we can calculate how many hours Mary worked by dividing the number of lamps she assembled by her rate, resulting in 30 hours (300 lamps / 10 lamps per hour).

Answer:

250 cubic cm

Step-by-step explanation:

First step is to measure the volume of the rectangular prism... which is easy... it's the width * length * height.  Since we have a square base, the width and length are the same: 5 cm.  The volume is then: 5 * 5* 12 = 300 cubic cm.

The volume of a pyramid is obtained by the following formula:

V = (1/3) * base_area * height

We have the base area (5 * 5 = 25) and we have the height: 6 cm (half of 12 cm).

So, the volume of the pyramid is:

V = (1/3) * 25 * 6 = (1/3) * 150 = 50 cubic cm

The volume inside the prism but OUTSIDE the pyramid is then the volume of the prism (300 cubic cm) - the volume of the pyramid (50 cubic cm), so 250 cubic cm.

Answer:

y = (3/5)x + 3

Step-by-step explanation:

You can see immediately that the y-intercept is (0, 3).

As we go right from the point (-5, 0) to the point (0, 3), x increases by 5 and y increases by 3.  Thus, the slope of this line is m = rise / run = 3/5.

Starting with the generic y = mx + b, we get y = (3/5)x + 3.

Answer:

Y=3/2x-3

Step-by-step explanation:

3/2 is the slope. Remember, rise/run. so the rise is 3 and the run is 2. so up three since its positive and right 2 cuz its positive. and the -3 is the y inercept. hope this helps love :)

Find the Greatest Common Factor (GCF)

GCF = 5x^2

Factor out the GCF. (Write the GCF first. Then in parenthesis, divide each term by the GCF)

5x^2(5x^4/5x^2 + 10x^3/5x^2 + -175x^2/5x^2)

Simplify each term in parenthesis

5x^2(x^2 + 2x - 35)

Factor x^2 + 2x - 35

= 5x^2(x - 5)(x + 7)

Answer:

14 gallons

Step-by-step explanation:

First determine the amount of miles per gallon her car will go by dividing the amount of miles by the amount of gallons.

228/9.5 = 24 miles per gallon

This means on a trip of 336 miles she will use 14 gallons.

336/24= 14 gallons

If there are 10 orders for every 65 students, and there are 416 students, the total amount of orders would be:

(416/65) x 10

= 64

Therefore, 64 students will order/eat pizza in Miss Jenkins School

The answer is 64 students.

Hope this helps!

Step-by-step explanation:

It,s where the line intercepts on the graph on the x and y axis

Answer:

The intercepts are where the line passes either the x-axis or y-axis. So depending on which intercepts you're looking for, the intercepts on the x-intercepts (x-axis) are (-4,0) and (0,0). the y-intercepts (y-axis) is (0,0).

Step-by-step explanation:

Answer:

A reflection across the y- axis

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y) → (-x, y)

A point in the second quadrant (- x, y)

Under reflection in the y- axis is (x, y) ← point in first quadrant

Answer:

A reflection across the y-axis.

Step-by-step explanation:

If it was across the x-axis, the point would have gone into Quadrant III.

The y-axis is vertical, and it was moved into Quadrant I from Quadrant II making it a vertical reflection which is a reflection from the y-axis.

The sum of the internal angles of a triangle must be equal to 180 degrees

so

Let

x----> the measure of the third angle

90°+65°+x=180°

Solve for x

155°+x=180°

x=180°-155°

x=25°

Volume of tissue box with 17 cm height and 8 cm side length base is 1088 cubic centimeters.

To find the volume of the tissue box, you can use the formula for the volume of a rectangular prism:

Volume = Base Area × Height

Since the base of the tissue box is a square, you can find the area of the base by squaring the side length:

Base Area = Side Length^2

Then, you multiply the base area by the height of the tissue box:

Volume = Base Area × Height

Let's plug in the values:

Side Length = 8 cm

Height = 17 cm

First, find the base area:

Base Area = 8 cm × 8 cm = 64 cm²

Then, calculate the volume:

Volume = 64 cm² × 17 cm = 1088 cm³

So, the volume of the tissue box is 1088 cubic centimeters.

The complete question is here:

A tissue box that has a height of 17 cm and that has a square base with a side length of 8 cm. What is the volume of a box of tissue?

Answer:

She will pay more

Step-by-step explanation:

because if you multiply 19x12 you get 228 which is more than 190.

Miss Lacey will pay more than $190 for a year of gym membership because 12 months multiplied by $19 per month equals $228, which is greater than $190.

To determine if Miss Lacey will pay more or less than $190 for a year of gym membership, we need to calculate the total cost for one year. Since a year has 12 months, and the membership cost is $19 per month, we multiply the monthly cost by the number of months in a year:

Annual cost = $19 per month × 12 months

Therefore, the annual cost is:

$19 × 12 = $228

Comparing the annual cost to $190, we find that Miss Lacey will pay more than $190 for a year of gym membership, since $228 is greater than $190. This calculation exemplifies a straightforward mathematical operation involving multiplication and comparison.

Answer:

Step-by-step explanation:

The difference between the third quartile and first quartile is known as interquartile range.

The upper quartile is the median of upper half of the data.

The lower quartile is the median of lower half of the data.

Let's arrange in least to greatest:

4,5,6,6,7,8,9,9,10,10,12,12,14,15

The upper half of the data is 9,10,10,12,12,14,15

The median is the 4th number here, so 12. Thus, third quartile = 12

The lower half of the data is 4,5,6,6,7,8,9

The median is the 4th number here, so 6. Thus, first quartile = 6

Interquartile range (difference in third quartile and first quartile) = 12 - 6 = 6

[tex]a_0 = -8[/tex]

[tex]a_1=-6[/tex]

[tex]x^2 +y^2 -8x - 6y = 0[/tex]

Step-by-step explanation:

The equation of the circle has the following form

[tex]x^2 + y^2 + a_0x + a_1y=0[/tex]

The equation of the circle has the following form

We know that the circle goes through the following points

(1, 7)

(8, 6)

(7, -1).

Then we substitute the values of x and y in the equation

For (1, 7)

[tex](1)^2 + (7)^2 + a_0(1) + a_1(7)=0[/tex]

[tex]1 + 49 + a_0 + 7a_1=0[/tex]

[tex]a_0 + 7a_1=-50[/tex]    (1)

For  (8, 6)

[tex](8)^2 + (6)^2 + a_0(8) + a_1(6)=0[/tex]

[tex]64 + 36 + 8a_0 + 6a_1=0[/tex]

[tex]8a_0 + 6a_1= -100[/tex]    (2)

With these equations is enough to solve the system

[tex]a_0 + 7a_1=-50[/tex]    (1)

[tex]8a_0 + 6a_1= -100[/tex]    (2)

Multiply the equation (1) by -8 and add it to the equation (2)

[tex]-8a_0 - 56a_1=400[/tex]    (1)

[tex]8a_0 + 6a_1= -100[/tex]    (2)

-----------------------------------------------------

[tex]-50a_1 = 300\\\\a_1 = -6[/tex]

Then

[tex]a_0 + 7(-6) = -50\\\\a_0 = -50+42\\\\a_0=-8[/tex]

Finally the equation is:

[tex]x^2 +y^2 -8x - 6y = 0[/tex]

I am pretty sure the answer would be (a)

Answer:

The weight of the larger marble paperweight is 4.05 lb

Step-by-step explanation:

we know that

If two solids are similar, then the ratio of its weights (or volumes) is equal to the scale factor elevated to the cube

Remember that the scale factor is the ratio between corresponding sides

Let

z ------> the scale factor

x -----> the weight of the larger marble paperweight

y -----> the weight of the original marble paperweight

[tex]z^{3} =\frac{x}{y}[/tex]

In this problem we have

[tex]z=3[/tex]

[tex]y=0.15\ lb[/tex]

substitute and solve for x

[tex]3^{3} =\frac{x}{0.15}[/tex]

[tex]x=(27)(0.15)=4.05\ lb[/tex]

therefore

The weight of the larger marble paperweight is 4.05 lb

Answer:

(2x+3)^2

=(2x+3)(2x+3)

=(2x)(2x)+(2x)(3)+(3)(2x)+(3)(3)

=4x^2+6x+6x+9

=4x^2+12x+9

The standard form of the given quadratic equation y = (2x + 3)^2 is y = 4x^2 + 12x + 9. This is achieved by applying the square of a binomial rule and simplifying.

The given equation is y = (2x + 3)^2. This is in the form of a squared binomial, which can be expanded and simplified into a standard form of a quadratic equation. The standard form of a quadratic equation is y=ax^2 + bx + c.

To convert the given equation into standard form, we need to apply the square of a binomial rule, which states that (A + B)^2 = A^2 + 2AB + B^2. Here, A = 2x and B = 3.

So, we can rewrite the equation as follows: y = (2x)^2 + 2*2x*3 + 3^2 = 4x^2 + 12x + 9. Therefore, the standard form of the given quadratic equation is y = 4x^2 + 12x + 9.

Answer:

a.  5 + 2i, 13 + 2i, 29 + 2i

Step-by-step explanation:

We'll use the formula  f(z) = 2z + (3 - 2i)  for each iteration. The output of the first iteration will be come the input of the second iteration, and so on.

So, we start with z0 = 1 + 2i and we plug that into the base equation:

z0 = 1 + 2i ==> f(z) = 2(1 + 2i) + 3 - 2i = 2 + 4i + 3 - 2i = 5 + 2i

z1 = 5 + 2i ==> f(z) = 2(5 + 2i) + 3 - 2i = 10 + 4i + 3 - 2i = 13 + 2i

z2 = 13 + 2i ==> f(z) = 2(13 + 2i) + 3 - 2i = 26 + 4i  + 3 - 2i = 29 + 2i

[tex]F (x) = x ^ 4-x ^ 2 + 4[/tex]

Step-by-step explanation:

We have the function [tex]G (x) = x ^ 4-x ^ 2[/tex] and we know that it contains the point (0,0). That is, it cuts the y axis and y = 0

Then the graph of F(x) is shown in the image and we know that it is a transformation of F(x).

The function F(x) cuts the y axis and y = 4.

For this reason we can conclude that the function F(x) is the function G(x) displaced 4 units upwards.

The transformation that shifts the graph of a function k units upwards is:

[tex]F (x) = G (x) + k[/tex]

Where [tex]k> 0[/tex].

In this case k = 4. Therefore:

[tex]F (x) = G (x) +4\\\\F (x) = x ^ 4-x ^ 2 + 4[/tex]

The answer is Option B
