Answer 2

Answer:
y-intercept is 10
slope of line is 7

Explanation:
The general form of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept

Now, the given equation is:
y = 7x + 10

Comparing the given equation with the general form, we will find that:
m = 7 .............> This means that the slope of the line is 7
c = 10 ............> This means that the y-intercept is 10

Now, the y-intercept here means that the initial number of points at time = 0 (x=0) is 10 points.

The slope here means that the rate increases by 7 points each second

find the separate equations form the lins represented by 3x^2 + 10xy + 8y^2 + 14x + 22y + 15

Answers

3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = 0

3x^2 is factorable only as 3x and x.
15 can be 15 * 1 or 3 * 5.
As a first guess, I place 5 and 3 in that order.
The coefficients of y are unknown so far.

= (3x + Ay + 5)(x + By + 3)

= 3x^2 + 3Bxy + 9x + Axy + ABy^2 + 3Ay + 5x + 5By + 15

(3B + A)xy = 10xy

(3A + 5B)y = 22y

A + 3B = 10
3A + 5B = 22

-3A - 9B = -30
3A + 5B = 22

4B = 8

B = 2

A + 3B = 10

A + 6 = 10

A = 4

3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = (3x + 4y + 5)(x + 2y + 3)

The product of (3x + 4y + 5)(x + 2y + 3) is indeed
3x^2 + 10xy + 8y^2 + 14x + 22y + 15

The lines are
3x + 4y + 5 = 0
x + 2y + 3 = 0

A square pyramid and a cube have the same volume if the length of each side of the base of the square pyramid is 2 cm in the height of the cube is 4 cm what is the height of the pyramid

a 8cm
b 16cm
c 24cm
d 48 cm

Answers

Vol sq. pyramid = 1/3×s^2×h
Vol cube = s^3
since height of cube is 4, that height = s
V = (4)^3 = 64 cubic cm
now since their Vs are the same,
1/3×s^2×h = 64
they said length of side in square pyramid
was 2, then:
1/3×(2)^2×h = 64
1/3×4×h = 64
4/3 h = 64
h = 64×3/4 = 16×3 = 48 cm

Let’s then substitute m for 2. Then a would be 16 because 8*2 equals 16. Both add 5 and you get 21 and 7. 21 is 3 time more than 7.

Answer: 24 cm

Explanation:

Let
P = area of triangle ABC
Q = area of triangle ACD

The two areas mentioned above are in ratio 1.5:1 which basically means
P = 1.5*k
Q = 1*k
for some value k
Notice how P/Q = (1.5k)/(1k) = 1.5 which proves that P:Q = 1.5:1

We can find the value of k by determining the area of triangle ABC
P = area of triangle ABC
P = (base)*(height)/2
P = 36*10/2
P = 360/2
P = 180

If P = 180, then
P = 1.5*k
1.5*k = 180
k = 180/1.5
k = 120

Telling us that
Q = 1*k
Q = 1*120
Q = 120
Q = area of triangle ACD
area of triangle ACD = 120
note how P/Q = 180/120 = 1.5 so P:Q = 1.5:1

We'll use this area to find the base of triangle ACD which is AD

Area of Triangle ACD = (base)*(height)/2
120 = AD*10/2
120*2 = AD*10
240 = AD*10
240/10 = AD
24 = AD
AD = 24

The near and far faces appear to be trapezoids, with bases 12 in and 8 in and height 8 in. Hence each of them has an area
.. Atrapezoid = (1/2)(b1 +b2)h
.. = (1/2)(12 in + 8 in)*(8 in)
.. = 80 in^2

The remaining faces unroll into a rectangle 8 in wide and (12 +8 +8+9) in long. The area of a rectangle is the product of its length and width.
.. Arectangle = length*width
.. = (37 in)*(8 in) = 296 in^2

The total surface area is the sum of the rectangle area and the two trapezoidal faces.
.. Atotal = Arectangle + 2*Atrapezoid
.. = 296 in^2 +2*80 in^2

S = √3*73.5 /4.5=7 (Khufu’s pyramid)

The volume of Khafre’s pyramid is about 9/10 the volume of Khufu’s pyramid. If Kristina wants to make the second model pyramid so its volume is 9/10 the volume of the first model pyramid, what volume should she make the second model pyramid?

This goes with the other questions! if you need information i can get that for you!
Also, could you work it out!

Answers

3/6 should b you answer answer

Final answer:

The volume will be of 6.3 for the second model.

Explanation:

The student is asked to calculate the volume of the second model pyramid, Khafre's pyramid, which is 9/10 the volume of the first model, Khufu's pyramid. The student has already calculated that, for Khufu's pyramid, S = √3*73.5/4.5=7. To find the volume Kristina should make the second model, we simply multiply the volume of the first model by 9/10.

Although the question does not provide the exact volume of the first model, we will assume the value of S given is the volume of Khufu's pyramid model. Therefore, the volume of Khafre's pyramid model should be 7 * (9/10) = 6.3.

This result is based on the proportion given between the two pyramids' volumes and is a straightforward calculation of this proportion.

Joel is looking at costs for using a gym. He could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit. How many visits would he have to make each month to make the $50 per month unlimited use option the cheapest one?

Answers

[tex]y = 4x + 12[/tex]
Joel would have to go at least 10 times per month to make the 50 dollars per month the cheapest one.

Answer:

First choice is cheaper.

Step-by-step explanation:

Joel could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit.

Let the monthly visits be x

We can define this as :

[tex]12+4x> 50[/tex]

[tex]4x >50-12[/tex]

[tex]4x >38[/tex]

[tex]x> 9.5[/tex]

So, x can be greater than 9.5 means 10.

[tex]4(10)+12>50[/tex]

[tex]52 > 50[/tex]

Comparing both we can say that the first choice is cheaper.

A probability experiment is conducted wich of these can not be considered a probability of an outcome: a) 0.222 b) 8.2% c) 0.0234 d) 122.96% e) 5/3 f) 0.45%

Answers

Probability can only range from 0 to 1 and d) 122.96% and e) 5/3 is bigger than 1 so the answer would be d and e.

122.96% and 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. Correct option is d and e.

In probability, the probability of an outcome must be a value between 0 and 1, inclusive. Therefore, any value less than 0 or greater than 1 cannot be considered a probability of an outcome.

Let's check each option:

a) 0.222 - This is a valid probability since it is between 0 and 1.

b) 8.2% - This can be converted to a decimal as 0.082, which is a valid probability since it is between 0 and 1.

c) 0.0234 - This is a valid probability since it is between 0 and 1.

d) 122.96% - This can be converted to a decimal as 1.2296, which is not a valid probability since it is greater than 1.

e) 5/3 - This can be simplified to approximately 1.6667, which is not a valid probability since it is greater than 1.

f) 0.45% - This can be converted to a decimal as 0.0045, which is a valid probability since it is between 0 and 1.

Therefore, options (d) 122.96% and (e) 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. The other options are valid probabilities as they fall within the range of 0 to 1, inclusive.

ANSWER

The given system of equations has no solution.

EXPLANATION

We write the two equations in the slope-intercept form,

[tex]y = mx + c[/tex]

The first equation is
[tex]2x - y = 7[/tex]

We make y the subject to obtain,

[tex]y = 2x - 7 - - (1)[/tex]

The second equation is already in slope intercept form.

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

We can see that the two equations have the same slope but different y-intercept. This implies that, the two equations will never intersect. Therefore the system of equations has no solution.

Answers

the answer is 60 dollars

Madeline has approximately $400 after rounding her garage sale earnings and paycheck to the nearest ten and adding them together.

The question involves estimating the total amount of money Madeline has after selling items at a garage sale and receiving her paycheck. To estimate the total amount, we need to round each amount to the nearest ten and then add the rounded numbers together.

First, round $167 to the nearest ten, which is $170.

Next, round $232 to the nearest ten, which is $230.

Finally, add the rounded numbers: $170 + $230 = $400.
