Answer 1

Answer:

At the end of three months, you will owe £767

Step-by-step explanation:

First you find 7% of 1000

= 70

70 is added to the £1000 every month so

1070 - 150 = 920

990 - 150 = 840

917 - 150 = 767

What is the slope of the line?

I WILL MARK AS BRAINLY

Answers

Answer:

[tex]\frac{4}{7}[/tex]

Step-by-step explanation:

In order to find the answer to this question you must choose two points anywhere on this line as long as the line intercepts then solve for slope.

slope = change in y / change in x

[tex]slope = \frac{y2-y1}{x2-x1}[/tex]

[tex]P = (-1,-3)[/tex]

[tex]P=(3,4)[/tex]

Substitute:

[tex]\frac{3--1}{4--3}[/tex]

Solve:

[tex]3--1=3+1=4[/tex]

[tex]4--3=4+3=7[/tex]

[tex]=\frac{4}{7}[/tex]

If the lengths of two sides of a right triangle are 5 and 12 units, what is the least possible length, in units, of the third side? Express your answer in simplest radical form.

Answers

(leg)^2 + (leg)^2 = (hypotenuse)^2

(5)^2 + (12)^2 = (h)^2

25 + 144 = (h)^2

169 = (h)^2

sqrt{169} = sqrt{(h)^2}

-13 = h

13 = h

We reject h = -13 because length is a distance and distance cannot be negative.

So, h = 13 units is the answer.

Answer:

Answer is B, V = π(7)² · 20

Step-by-step explanation:

the formula for a cylinder is V = πr²h

So, from here you just plug in numbers.

but for "r" you need to take 14 and divide it by 2 since it is in the form of a diameter which is different to a radius or "r".

14/2 = 7

Now, you can plug in numbers,

V = π(7)² · 20

Answers

Step-by-step explanation:

The y-intercept formula is y=mx+b

(m) is the slope

(b) is the y intercept

So in the given formula -45 would be the slope and 270 is the y intercept.

Answer:900

Step-by-step explanation:

If the point (0, 20) is the y-intercept of the parabola with the vertex is (8, -12), What is the equation for this parabola.

Answers

Answer:

f(x) = ¹/₂(x - 8)² - 12

Step-by-step explanation:

f(x) = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (8, -12) is

f(x) = a(x - 8)² - 12

The point (0, 20) is the y-intercept means if x=0 then f(x)=20

20 = a(0 - 8)² - 12

20 +12 = 64a - 12 +12

32 = 64a

a = ³²/₆₄ = ¹/₂

Therefore the equation (in vertex form) of parabla is:

f(x) = ¹/₂(x - 8)² - 12

1. The ratio of boys to girls in the sixth grade is 2 : 3.
a. If there are 24 boys, how many girls are there?
b. If there are 80 students, how many are girls?
c. If there are 75 students, how many more girls are there than
boys?

Answers

Answer:

a. 36 girls

b. 48 girls

c. 15 more girls than boys

Step-by-step explanation:

a. if the ratio for the question is 2:3 with a refernce ratio of 24:X, with cross multiplication we find out the x=36

b. now we must separate 80 into the 2:3 ratio making 32:48 with 48 girls

c. the same thing will be done with 75, making its 2:3 ratio 30:45, to find the difference of the two numbers you must subtract, this shows that the difference is 15 more girls.

Which inequality contains (0,0)

Answers

Answer:

Step-by-step explanation:

I believe C is the answer.

Explanation: If it helps, plug both the x and y values in each inequality. For the first, 0 is greater than -5, so A is not the answer. For the second, 0 is less than 3, so B is not the answer. For the last, there is no equal sign, so D is not the answer. (In order to make the inequality true, it has to be a greater than or equal to sign.) Now, for the third, 0 IS greater than -4, making that inequality true.
