Please help me with this maths question, brainiest and points will be given. THANK YOU!!!

Given :

Total amount, T = 10000 . ( It should not 1000 )

Annual rates of interest in both scheme is 8% and 9% .

After one year he got 875 rupees as interests from both.

To Find :

How much did he invest in each.

Solution :

Let, amount invested in 8% annual interest scheme is x.

So, amount in other scheme is 10000-x .

Now, sum of interest is equal to 875.

[tex]\dfrac{x\times r_1 \times 1}{100}+\dfrac{(10000-x)\times r_2\times 1}{100}=875\\\\8x + 9(10000-x)=87500\\\\x = 90000-87500\\\\x = 2500[/tex]

Therefore, amount invested in 8% and 9% annual interest scheme is 2500 and 7500 rupees respectively.

Hence, this is the required solution.

Answer:

119

Step-by-step explanation:

Given f(x) divided by (x - h) then the value of f(h) is the remainder, thus

f(6) = 2(6)³ - 9(6)² + 11

     = 2(216) - 9(36) + 11

     = 432 - 324 + 11

     = 119 ← remainder

Answer:

AC= longest side

BC=middle side

AB=shortest side

Step-by-step explanation:

there is 180 degrees in a triangle, therefore

95+50=145

180-145=35

so we have angles 95, 50, 30

and we know that the side opposites with the angle corresponds to how big the side will be compared to the other sides

Therefore,

AC= longest side

BC=middle side

AB=shortest side

Step-by-step explanation:

-7 - (-2)

-7 + 2

Example: If you owe someone $7, and you give them $2, how much do you still owe? You are owing him $7 so it's a negative and you give him $2 which is a negative as well since you are giving it to him. So, to answer how much do you still owe, you would add $2  to the $7 you owed, so now, you owe him $5, which is a negative since you OWE him.

sorry im a bit late lol

The solution is, The shape that is generated is a Cone, when AABC is rotated around the vertical line through B and C.

A cone is a solid which tapers from a circular base to a point. A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex.

here, we have,

given that,

triangle ABC is rotated around the vertical line through B and C.

now, we have to find shape that is generated .

we know that,

A triangle, when rotated about one of it's side will generate a solid in a form of a Cone.

again, we have,

The cone could be a hollow one or a solid filled one, depending on the properties of the triangle being rotated.

Hence, The solution is, The shape that is generated is a Cone, when triangle ABC is rotated around the vertical line through B and C.

Answer:

La cantidad de horas que trabajó Hugo son 8, mientras que Eduardo trabajó 32 horas y Francisco 64 horas.

Step-by-step explanation:

En primer lugar, para determinar la ecuación que debes resolver, es conveniente establecer la variable a la que debes encontrar una solución en la ecuación. Entonces, llamas x a la cantidad de horas que trabajó Hugo.

Luego, sabes que Eduardo trabajó el cuádruple de horas de las que trabajó Hugo, esto es, cuatro veces más de las horas trabajadas por Hugo. Esto se expresa matemáticamente como 4*x.

Finalmente, Francisco trabajó el doble de horas que Eduardo, que se calcula multiplicando a las horas trabajadas por Eduardo por 2: 2*4*x= 8*x

Entre los tres hermanos trabajaron 104 horas. Esto indica que la suma de las horas trabajadas por Francisco, Eduardo y Hugo debe ser 104 horas. Esto se expresa matemáticamente como:

x + 4*x+ 8*x= 104 (Planteamiento algebraico)

Resolviendo (Procedimiento):

13*x=104

[tex]x=\frac{104}{13}[/tex]

x=8

Esto significa que la cantidad de horas que trabajó Hugo son 8.

Eduardo trabajó 4*x, esto es 4*8, que da como resultado 32 horas. Entonces Eduardo trabajó 32 horas.

Por último, Francisco trabajó 8*x. Siendo x=8, entonces 8*8=64. Entonces Francisco trabajó 64 horas.

Hugo trabajó 8 horas, Eduardo trabajó 32 horas y Francisco trabajó 64 horas.

Dado que tres albañiles trabajaron en una construcción, y Francisco trabajó el doble de horas que Eduardo y Eduardo trabajó el cuádruple de horas de las que trabajó Hugo, y entre los tres hermanos trabajaron 104 horas, para determinar cuántas horas trabajó cada uno se debe realizar el siguiente cálculo:

Así, Hugo trabajó 8 horas, Eduardo trabajó 32 horas y Francisco trabajó 64 horas.

Answer:

34sq. units

Step-by-step explanation:

The area of the rectangle shown is expressed as;

A = length *width

The length = AD = BC

Width = AB =  CD

From the diagram, we will look for AD and AB using the formula for calculating distance between two points;

D = √(x2-x1)²+(y2-y1)²

For AB where A(-1,4) and B(3,3)

AB = √(3-(-1))²+(3-4)²

AB = √(4)²+(-1)²

AB =√16+1

AB = √17

For AD where A(-1,4) and D(-3,-4)

AD = √(-3-(-1))²+(-4-4)²

AD = √(-2)²+(-8)²

AD =√4+64

AD = √68

Hence area of the rectangle = √17*√68

Hence area of the rectangle = √1156

Hence area of the rectangle = 34

Hence area of the rectangle ≈ 34sq. units

Answer:

y = -2x - 4

Step-by-step explanation:

Formula is y = mx + b where m is the slope and b is the y-intercept

(1, -6) (-3, 2)

[tex]\frac{-6-2}{1-(-3)}=\frac{-8}{4} =-2[/tex]

The slope is -2

y = -2x + b

So let's find b, insert 2 for y and -3 for x to find b

2 = -2(-3) + b

2 = 6 + b

Subtract 6 from both sides to get b alone

-4 = b

We found what b equals (the y-intercept), which is -4

So, the equation is y = -2x - 4

If the function f(x) = 4x – 8 is reflected across the y-axis. Then the reflected function will be g(x) = – 4x – 8.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

It is the image of the line which is located in the opposite direction of a given line.

The function f(x) = 4x – 8 is reflected across the y-axis.

If the function f(x) = 4x – 8 is reflected across the y-axis, then replace x with negative x. Then the reflected function will be

g(x) = – 4x – 8

Answer: 12.96 trillion pounds

Step-by-step explanation:

From the question, we are informed that:

1 trillion pounds = 0.4536 billion metric tons

Therefore, if the US released 5.877 billion metric tons of carbon dioxide, the trillions of pounds of carbon dioxide that the US release will be:

= 5.877 / 0.4536

= 12.96 trillion pounds

Answer: 164.32 miles

Step-by-step explanation:

Given that:

Weekly coverage :

Miles biked to the river = 0.86 miles

Miles biked along the river back home =. 2.3 miles

Total miles biked weekly:

(0.86 + 2.3) miles = 3.16 miles weekly

Number of weeks per year = 52

Miles biked yearly : (number of weeks per year * miles biked weekly)

= 52 * 3.16 miles

= 164.32 miles

Mrs endo will bike about 164.32 miles in a year.

Answer:

29

Step-by-step explanation:

27 + 28 + 29 = 84

Answer:

D

Step-by-step explanation:

Let the first number be n.

Then the consecutive number will be (n+1).

And the second consecutive number will be (n+2).

We know that it totals 84. So, we can write the following equation:

[tex]n+(n+1)+(n+2)=84[/tex]

Let’s now solve for n. Combine like terms:

[tex]3n+3=84[/tex]

Subtract 3 from both sides:

[tex]3n=81[/tex]

Divide both sides by 3:

[tex]n=27[/tex]

So, our n or first term is 27.

This means that our sequence is: 27, 28, and 29.

So, our largest number is 29.

Hence, our answer is D.

Answer:

3.3°

Step-by-step explanation:

The set up of the question will give a right angled triangle where the height covered by the bal is the opposite side.

The length at which the pitcher hit the ground is the hypotenuse.

Given

Opposite side = 3.4m

Hypotenuse = 58.8m

Required

Angle of depression

Using SOH CAH TOA trigonometry identity

According to SOH,

Sin(theta) = opposite/hypotenuse

Sin(theta) = 3.4/58.8

Sin(theta) =0.05782

theta = sin^-1(0.05782)

theta = 3.32°

Hence the angle of depression that he must release the ball to nearest tenth is 3.3°
