Write an expression to represent the sum of three times the square of a number and -7.
In your expression, what is the value of the constant?

Answer:

3

Step-by-step explanation:

Add the times together:

19/100 + 4/10

Find the common denominator, which is 100 so rewrite 4/10 as 40/100

Now add:

19/100 + 40/100 = 59/100

The first car beat the third car by 59/100 seconds.

Answer:

-262

Step-by-step explanation:

Given sequence is: 33, 28, 23, 18...

First term a = 33

Common Difference d = 28 - 33 = - 5

To find: [tex] t_{60}[/tex]

By nth term of an AP.

[tex]t_n = a + (n - 1)d \\ t_{60} = 33 + (60- 1)( - 5) \\ t_{60} = 33 + 59( - 5) \\ t_{60} = 33 - 295\\ t_{60} = - 262\\ [/tex]

Answer:

Option (A)

Step-by-step explanation:

Let the Sine of the given angle θ is,

Sinθ = [tex]\frac{x}{y}[/tex]

Then θ = [tex]\text{Sin}^{-1}(\frac{x}{y} )[/tex]

From the given values in the question,

Sinθ = [tex]\frac{7}{29}[/tex]

θ = [tex]\text{Sin}^{-1}(\frac{7}{29} )[/tex]

θ = 13.97°

Therefore, measure of the angle 'θ' will be 13.97°.

Option (A) will be the answer.

Answer:

Step-by-step explanation:

[tex] \frac{ {b}^{10} }{ {b}^{6} } [/tex]

Using the rules of indices

That's

[tex] \frac{ {a}^{x} }{ {a}^{y} } = {a}^{x - y} [/tex]

Since the bases are the same and are dividing we subtract the exponents

So we have

[tex] \frac{ {b}^{10} }{ {b}^{6} } = {b}^{10 - 6} [/tex]

We have the final answer as

Step-by-step explanation:

b¹⁰ / b⁶ = b¹⁰ ⁻⁶ = b⁴

Answer:

Step-by-step explanation:

The question lacks the required diagram. Find the diagram in the attachment.

The flag is rectangular in nature and the formula for calculating the perimeter of a rectangle is P = 2(L+W) where;

L is the length of the flag

W is the width of the flag

From the diagram, L = y and W = 11y/8

Since the perimeter = 190 inches, we will substitute the given parameters into the formula and firs calculate the value of y.

190 = 2(y+11y/8)

190 = 2y + 11y/4

multiply through by 4

760 = 8y+11y

760 = 19y

y = 760/19

y = 40

The length of the flag is 40 inches and the Width of the flag is 11(40)/8 = 55inches.

Hence, the dimensions of the flag in inches is 40 inches by 55 inches.

Answer: Hi!

A number that is bigger than 5 2/3 but smaller than 6 could be 5.7.

A number that is bigger than 5.6 but smaller than 5 2/3 could be 5.62.

Hope this helps!

In fact 5 2/3 means 5+2/3 for this. So,5+2/3 = 17/3 = 5.6

For first question, if "numbers" are also include rational numbers, you can write any rational number according to this interval. For example, 5.7 , 5.75, 5.9

But the second one, the interval that is shown us has the same value 5.6 and 5.6. So you cannot find a number which should bigger 5.6 and smaller 5.6 . It seems impossible I mean.

Answer:

your answer is 19.34

Step-by-step explanation:

let the number be x

half a number = ½ x

three times means multiplied by three

so,

3( ½ x) + 7 = 36

3( ½ x) = 36 - 7

3( ½ x) = 29

½ x = 29/3

½ x = 9.67...

x = 9.67 × 2           (when we moved  ½ on the other side of the equal sign it                                      ›                               turns into 2/1 )

x = 19.34

Answer:

[tex] \boxed{\sf Perimeter \: of \: rectangular \: garden = 10x + 2} [/tex]

[tex] \boxed{\sf Area \: of \: rectangular \: garden = 6x^2 + x - 2} [/tex]

Given:

Length of rectangular garden = 2x - 1

Width of rectangular garden = 3x + 2

Step-by-step explanation:

[tex] \sf Perimeter \: of \: rectangular \: garden = 2(Length + Width)[/tex]

[tex] \sf = 2((2x - 1) + (3x + 2))[/tex]

Grouping like terms:

[tex] \sf = 2((2x + 3x) + (2 - 1))[/tex]

2x + 3x = 5x:

[tex] \sf = 2(5x + (2 - 1))[/tex]

2 - 1 = 1:

[tex] \sf = 2(5x + 1)[/tex]

[tex] \sf = (2 \times 5x) + (2 \times 1)[/tex]

2 × 5x = 10x:

[tex] \sf = 10x + (2 \times 1)[/tex]

2 × 1 = 2:

[tex] \sf = 10x + 2[/tex]

[tex] \therefore[/tex]

Perimeter of rectangular garden = 10x + 2

[tex] \sf Area \: of \: rectangular \: garden = Length \times Width[/tex]

[tex] \sf = (2x - 1)(3x + 2)[/tex]

[tex] \sf = 2x(3x + 2) - 1(3x + 2)[/tex]

[tex] \sf = (2x \times 3x) + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]

2x × 3x = 6x²:

[tex] \sf = 6 {x}^{2} + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]

2x × 2 = 4x:

[tex] \sf = 6 {x}^{2} + 4x - (1 + 3x) - (1 \times 2)[/tex]

1 × 3x = 3x:

[tex] \sf = 6 {x}^{2} + 4x - 3x - (1 \times 2)[/tex]

1 × 2 = 2:

[tex] \sf = 6 {x}^{2} + (4x - 3x) - 2[/tex]

4x - 3x = x:

[tex] \sf = 6 {x}^{2} + x - 2[/tex]

[tex] \therefore[/tex]

Area of rectangular garden = 6x² + x - 2

Answer:

Perimeter = 10x+2 m

Area = 6x²+x-2 m²

Step-by-step explanation:

Length of garden (l) = 2x-1

width or breadth of garden ( b) = 3x+2

Now,

Perimeter of the garden (p) = 2( l + b)

= 2 ( 2x-1 + 3x+2 )

= 2 ( 5x + 1 )

= 10x+2 m. ( Answer )

Again,

Area of garden (a) = l * b

= ( 2x-1 ) ( 3x+2 )

= 2x ( 3x+2 ) -1 ( 3x+2 )

= 6x² + 4x - 3x - 2

= 6x²+x-2 m². ( Answer )

Answer:

13

1.57

Step-by-step explanation:

So we have two equations regarding the number of quarters q and the number of pennies p:

[tex]p+q[/tex]

Which represents the total amount of coins and

[tex]0.01p+0.25q[/tex]

Which represents the total amount of money in dollars.

So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for q and 7 in for p:

[tex]p+q\\(7)+(6)=13[/tex]

This tells us that we have 16 coins in total.

[tex]0.01(7)+0.25(6)\\=0.07+1.50\\=1.57[/tex]

This tells us that we have a total amount of $1.57.

Answer:

[tex]\Large \boxed {13} \\ \boxed{ 1.57}[/tex]

Step-by-step explanation:

Pennies ⇒ [tex]p[/tex]

Quarters ⇒ [tex]q[/tex]

First expression describes the total number of coins in the pocket ⇒ [tex]p+q[/tex]

Second expression describes the amount of money in dollars in the pocket ⇒ [tex]0.01p+0.25q[/tex]

There are 6 quarters and 7 pennies in the pocket.

First expression :

[tex]p+q \\ 7 + 6 = 13[/tex]

Second expression :

[tex]0.01p+0.25q \\ 0.01(7)+0.25(6) \\ 0.07+1.5 =1.57[/tex]

Answer:

x = 30

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , thus

x + 4x + 30 = 180

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Answer:

x=150°

Step-by-step explanation:

A=180-60=120

B=180-60=120

C=45

D=360-120=240

E=45

The sum of the interiors of a polygon is (n-2)*180.  Since this is a hexagon, (6-2)*180=4*180=720. SO..

B=720-120-120-45-240-45=150

Assuming the questions is asking to solve for x, the angle is 150°

D. Quadrant IV

Step-by-step explanation:

Directed numbers are numbers with either a positive sign or a negative sign. These numbers can be located easily on the number line. Examples are: 2, 5, -1, -3, -7, 9 etc.

Given that: x > 0 and y < 0

For example, let us consider specific directed number for x and y. Let x = 5 and y = -2, so that; (5, -2). This point can be located in the fourth quadrant of a Cartesian plane.

Therefore considering a Cartesian plane, the quadrant in which (x, y) could be located is: Quadrant IV.

Answer:

120

Step-by-step explanation:

The computation of the other integer is shown below:

The Factor of 48 is 2^4 × 3

Also the greatest common divisor is 24,

This results that the second number also contains the factors 2^3 and 3 but not a fourth 2.

Now when there is a division of 240 by 48 so the number comes is 5

Now the second number factors are 2^3 and 3 that represents that it is under the factors of 48 but the factor 5 would arise from the second number

So, the other number is 120

Answer:

120

Step-by-step explanation:

If you want the aops explanation:

The prime factorization of 48 is $2^4\cdot3$. Since the greatest common factor is 24, that means the other number also has the factors $2^3$ and 3 but not a fourth 2. When we divide 240 by 48, we get 5. The factors $2^3$ and 3 of the other number are covered by the factors of 48, but the factor 5 must come from the other number. So, the other number is $2^3\cdot3\cdot5=\boxed{120}$.
