Lets write this out:-

112.50 ÷ 7.50 = ?
112.50 ÷ 7.50 = 15

7.50 can go in 112.50 evenly 15 times.

CHECK OUR WORK:-
15 × 7.50 = 112.50
we were RIGHT!!

So, 122.50 divided by 7.50 is 15.

Hope I helped ya!! xD

URGENT HELP
Katena32 [7]

Answer:

a = -6

b = 1

Step-by-step explanation:

The gradient of the tangent to the curve y = ax + bx^3, will be:

dy/dx = a + 3bx²

at (2, -4)

dy/dx = a+3b(2)²

dy/dx = a+12b

Since the gradient at the point is 6, then;

a+12b = 6 ....1

Substitute x = 2 and  y = -4 into the original expression

-4 = 2a + 8b

a + 4b = -2 ...2

a+12b = 6 ....1

Subtract

4b - 12b = -2-6

-8b = -8

b = -8/-8

b = 1

Substitute b = 1 into equation 1

Recall from 1 that a+12b = 6

a+12(1) = 6

a = 6 - 12

a = -6

Hence a = -6, b = 1

If &lt;ABC measures 100 and is inscribed in a circle O. find &lt;BAO and &lt;BCO​
satela [25.4K]

Answer:

<BCO​ = <BAO​ = 20degrees

Step-by-step explanation:

If <ABC measures 100 and is inscribed in a circle O. find <BAO and <BCO​

To get <BAO and <BCO​, we need to get <AOC first.

From the figure, it can be seen that triangle ABC is an isosceles trinagle. Hence;

<BAC + <BCA + 100 = 180

Since <BAC = <BCA

<BAC + <BAC = 180 - 100

2<BAC = 80

<BAC = 80/2

<BAC = 40

Also;

<BAO = <BCO​ and <BAO = <BAC/2

<BAO = 40/2 = <BCO​

Hence <BCO​ = <BAO​ = 20degrees

Which trinomials are perfect square trinomials?
taurus [48]
You can know a perfect square trinomial:

i) if the coefficient of a² = 1.

ii) If you divide the middle number coefficient by 2 and you square it you get the last term.

Take for example the first option: 

For all the options, the coefficient of a² = 1

a² + 4a + 16.

Coefficient of a = 4.
4/2 = 2
2² = 4, this does not equal the last term so it is not a perfect square trinomial.


a² + 14a + 49.

Coefficient of a = 14.
14/2 = 7
7² = 49, this is equal the last term so it is a perfect square trinomial.
And the perfect square is (a +7)²


Similarly if you test the last option.

a² + 26a + 169.

Coefficient of a = 26.
26/2 = 13
13² = 169, this is equal the last term so it is a perfect square trinomial.
And the perfect square is (a +13)²

So the only two options are: a² + 14a + 49 and a² + 26a + 169.

Other options do not pass this test.

Simplify the expression.
levacccp [35]
Hi there! The answer is 30.

We need to use PEMDAS to simplify.
P = parenthesis
E = Exponents
M = Multiply
D = Dividing
A = Adding
S = Subtracting

10(4 \times 10 \div ( {6}^{2} - {4}^{2} ) + 1)
First find the exponents inside the middlest parenthesis.

10(4 \times 10 \div (36 - 16) + 1)
Now add inside the parenthesis.

10(4 \times 10 \div 20 + 1)
Multiply inside the parenthesis that are left.

10(40 \div 20 + 1)
Divide inside the parenthesis

10(2 + 1)
Add inside the parenthesis.

10(3)
Multiply.
