Answer: should be 16.

Step-by-step explanation:

Because 3 fourths of 16 is 12.

Answer:

16 and 14 years old.

Step-by-step explanation:

Let their ages be x and y years, then

x + y = 24 .......... (1)

Also from the given information

(x - 5)/ (y - 5) = 3/4

3y - 15 = 4x - 20

3y - 4x = -5

Multiplying equation (1) by 3:

3y + 3x = 72

Subtracting these last 2 equations:

-7x = -77

x = 11.

So y = 24 - 11 = 13.

So in 3 years time they will be 16 and 14.

Answer:

Peter would be 14. Paul would be 16

Step-by-step explanation:

Variable labels:

Peter = m, Paul = n

m + n = 24

(m - 5) : (n- 5) = 3:4

The ratio 3:4 in fraction form is [tex]\frac{3}{4}[/tex]

The ration of (m - 5) : (n- 5) in fraction form is [tex]\frac{m - 5}{n - 5}[/tex]

[tex]\frac{m-5}{n-5} = \frac{3}{4}[/tex]

Cross multiply:

4(m - 5) = 3(n - 5)

4m - 20 = 3n - 15

4m = 3n + 5

Find the value of m first:

4m = 3n + 5

m = [tex]\frac{3n + 5}{4}[/tex]

Now going back to the equation m + n = 24, substitute m with [tex]\frac{3n + 5}{4}[/tex] :

m + n = 24

[tex]\frac{3n + 5}{4}[/tex] + n = 24

Solve for n:

[tex]\frac{3n + 5}{4}[/tex] + n = 24

[tex]\frac{3n}{4} + \frac{5}{4}[/tex] + n = 24

[tex]\frac{7n}{4} +\frac{5}{4}[/tex] = 24

[tex]\frac{7n}{4} = \frac{91}{4}[/tex]

n = 13 (Paul's age)

Solve for m:

m + n = 24

m + 13 = 24

m = 11 (Peter's age)

After three years, Peter would be 11 + 3 = 14 years old and Paul would be 13 + 3 = 16 years old.

Answer: 15

Step-by-step explanation:

45$ = 3 Tickets

45 / 3 = 1 Ticket

1 Ticket = 15

The cost of the concert ticket is 15 dollars per ticket.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given that Three concert tickets cost $45.

To determine the cost per ticket.

Therefore,

45$ = 3 Tickets

For the unit cost of the concert ticket.

45 / 3 = 1 Ticket

1 Ticket = 15

Hence, the cost of the concert ticket is 15 dollars per ticket.

Answer: 0.9972

Step-by-step explanation:

Let x be a random variable that represents the strength of concrete cylinders.

Given: The compressive strengths of 40 concrete cylinders have an estimated mean[tex](\mu)[/tex] of 60.14 MPa and standard deviation[tex](\sigma)[/tex] of 5.02 MPa.

The probability that 10 cylinders will each have strengths between 45 and 75 MPa :

[tex]P(45<\overline{x}<75)=P(\dfrac{45-60.14}{5.02}<\dfrac{\overline{x}-\mu}{\sigma}<\dfrac{75-60.14}{5.02})\\\=P(-3.016<z<2.96)\\\\=P(z<2.96)-P(z<-3.016)\\\\=P(z<2.96)-(1-P(z<3.016))\\\\=0.9985-(1-0.9987)\ \ \ [\text{by p-value table}]\\\\= 0.9972[/tex]

Hence, The required probability = 0.9972

Answer: Nonlinear; power of x is greater than 1 (Bottom right corner)

Explanation:

The equation y = x^2 - 1 is known as a quadratic since the largest exponent here is 2. This equation cannot be written in slope intercept form y = mx+b, so that's why it's not linear. You can also graph y = x^2-1 to get a curved parabola. The graph must be a straight line if you want a linear equation.

WS=39

WY=78

The measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

A triangle is a three-sided polygon that consists of three edges and three vertices.

Z is the centroid of triangle.

The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle.

WR=87 SY=39 and YT=48

We need to find WS,WY,WZ,ZR,ZT and YZ

WS=39

As WS=WR

WY=WS+SY

WY=39+39=78

WZ=58

ZR=WR-WZ

ZR=87-48=29

ZT=16

YZ=YT-ZT

=48-16=32

YZ=32

Hence, the measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32
