Answer:

30

Step-by-step explanation:

Cross Multiply - 15 times 42 = 630

630 = 21t

What is 630 / 21... = 30

t = 30

Answer:

21/15=42/t

Rewrite the equation as 42/t=21/15.

42/t=21/15

Cancel the common factor of 21 and 15.

42/t=7/5

Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.

42⋅5=t⋅7

Solve the equation for t.

t=30

Step-by-step explanation:

y = -9 ------(1)

9x -4y = -9 -------(2)

substitute (1) into (2)

9x - 4 (-9) = -9

9x = - 45

x = -5

Answer:

The odds are 12

Step-by-step explanation:

The odds of rolling an odd number from the sum of two rolls requires that we roll one even number from one die and an odd number from another die.

Thus the probability of the event is P(e) = 1/12.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

For the given situation,

The sample space for rolling two 6 sided dice is

[tex]s[/tex] = { [tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]

[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]

[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]

[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]

[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]

[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]}

So, [tex]n(s)=36[/tex]

Let the event be the probability that the sum is odd and the number on one of the dice is a 5

Consider that the probability that the sum is odd be a,

[tex]a =[/tex] { [tex](1,2),(1,4),(1,6),(2,1),(2,3),(2,5),(3,2),(3,4),(3,6),\\[/tex]

[tex](4,1),(4,3),(4,5),(5,2),(5,4),(5,6),(6,1),(6,3),(6,5) }[/tex] }

Consider that the probability that the number on one of the dice is 5 be b,

[tex]b=[/tex] { [tex](1,5),(2,5),(3,5),(4,5),(5,5),(6,5)[/tex] }

The probability of the event can be find by taking intersection of a and b

⇒[tex]e=a[/tex]∩[tex]b[/tex] = { [tex](2,5),(4,5),(6,5)[/tex] }

⇒[tex]n(e)[/tex] [tex]=3[/tex]

Probability (event )=[tex]\frac{n(e)}{n(s)}[/tex]

⇒[tex]p(e)=\frac{3}{36}[/tex]

⇒[tex]p(e)=\frac{1}{12}[/tex]

Hence we can conclude that the probability of the event is P(e) = 1/12

The graph that correctly represents the linear piece-wise function is the first graph.

A linear function is modeled by:

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

In which:

A cab company charges a $5 pick up fee and $1 for each mile up to 10 miles, hence:

[tex]y = 5 + x, x \leq 10[/tex]

Hence, at x = 10, we have that:

y = 5 + 10 = 15.

$2 per mile for each mile over $10, hence:

[tex]y = 15 + 2(x - 10), x \geq 10[/tex]

Hence, at x = 14, we have that:

y = 15 + 2(14 - 10) = 15 + 8 = 23.

Thus the first graph is correct.

Answer:

B= 17.1

Step-by-step explanation:

The formula for the area of a triangle is BH1/2

The word problem gives you the area and the height

Set the problem:

369.25= 42.4(1/2)(B)

42.4(1/2)=21.2

369.25=21.2B

Divide both sides by 21.2 to isolate the variable

17.41=B

Answer:

The original amount of the mortgage was $66231.45.

Step-by-step explanation:

In order to find the original amount of the mortgage, you can use the following formula to calculate the present value:

PV=FV/(1+r/n)^nt

PV=present value

FV=future value= 775*12*12=111.600

r=rate of interest=0.0440

n= number of compounding periods= 2

t= time in years=12

Now, you can replace the values on the formula:

PV=111600/(1+(0.0440/2))^2*12

PV=111600/(1.022)^24

PV=111600/1.685

PV=66231.45

According to this, the answer is that the original amount of the mortgage was $66231.45.

Answer: his percent of increase = 66.66%

Step-by-step explanation:

percent of increase = Increase/ Previous goal x 100

Previous goal = 3 goals

Yesterday's goal = 5 goals

Percent of increase = (5-3) / 3 x 100

=2/3 x 100

=0.6666 x 100

=66.66%

Answer:

26.69

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached

The missing side is x;

From the triangle we are given;

Opposite = x

Hypotenuse = 29

Angle of elevation = 67 degrees

Using the SOH CAH TOA identity;

Sin theta = opposite/hypotenuse;

sin 67 = x/29

x = 29sin67

x = 29(0.9205)

x = 26.69

Hence the length of the missing side is 26.69

All trigonometric ratios of triangle PQR were calculated.

In the given right triangle PQR

PR = 14

QR = 50

So, using Pythagoras' theorem

PQ = 48

Sine of an angle = Opposite side / Hypotenuse

cosine of an angle = Adjacent side/ Hypotenuse

Tangent of an angle = Opposite side/ Adjacent side

So, SinQ = 14/50 =7/25      

CosecQ = 1/SinQ = 25/7

CosQ= 48/50 = 24/25

SecQ = 1/CosQ = 25/24

TanQ = 14/48 = 7/24

CotQ = 1/tanQ = 24/7

SinR=24/25

CosecR = 1/SinR= 25/24

CosR=7/25

SecR = 1/Cosr = 25/7

TanR =24/7

CotR = 1/tanR = 7/24

Thus, All trigonometric ratios of triangle PQR were calculated.

Corresponding point on a unit circle is equal to [tex]\boldsymbol{\left [ \frac{-\sqrt{3}}{2},\frac{-1}{2} \right ]}[/tex]

So, option C. is correct.

A unit circle is a circle with radius is equal to one.

Any point on a unit circle is of the form [tex]\boldsymbol{\left ( cos\, \theta, \sin\, \theta \right )}[/tex]

Value of [tex]\theta[/tex] is [tex]\boldsymbol{\frac{7\pi}{6}}[/tex]

So, corresponding point on a unit circle is equal to [tex]\boldsymbol{\left [\cos \left (\frac{7\pi}{6} \right ),\sin \left (\frac{7\pi}{6} \right ) \right ]}[/tex]

[tex]\left [\cos \left (\frac{7\pi}{6} \right ),\sin \left (\frac{7\pi}{6} \right ) \right ]=\left [\cos \left (\pi + \frac{\pi}{6} \right ),\sin \left (\pi + \frac{\pi}{6} \right ) \right ][/tex]

                              [tex]=\left [ -cos\left ( \frac{\pi}{6} \right ),-\sin\left ( \frac{\pi}{6} \right ) \right ]\\=\boldsymbol{\left [ \frac{-\sqrt{3}}{2},\frac{-1}{2} \right ]}[/tex]

C) The graph opens down and the vertex is a maximum.

Step-by-step explanation:

Just took the quiz on K12, good luck! :)

Option (C) will be the correct option.

         f(x) = ax² + bx + c

         Vertex of the parabola is represented by [tex][-\frac{b}{2a}, f(\frac{b}{2a})][/tex]

         And the sign of the leading coefficient decides the opening of the

         parabola.

         For positive sign of 'a' → Parabola will open upwards

         For negative sign of 'a' → Parabola opens downwards

Quadratic function given in the question is,

f(x) = -4x²+ 6x - 7

Leading coefficient → (-4)

Negative sign represents the opening of the parabola downwards.

And the vertex will be a maximum.

           Therefore, Option (C) will be the correct option.
