Answer:

129.8 mmHg

42 years

Step-by-step explanation:

Given the relation :

P = 0.006 y² − 0.02 y + 121

Systolic blood pressure, P

Age, y

A.)

Find P when age y = 40

P = 0.006(40)² − 0.02(40) + 121

P = 9.6 - 0.8 + 121

P = 129.8 mmHg

B)

P = 130.74 mmHg

y =?

130.74 = 0.006y² − 0.02y + 121

130.74 - 121 = 0.006y² − 0.02y

9.74 = 0.006y² − 0.02y

0.006y² − 0.02y - 9.74 = 0

Using a quadratic equation solver :

The roots are 41.99 and - 38.66

Age cannot be negative ;

Hence age = 41.99 = 42 years

Answer:

3 ft^2

Step-by-step explanation:

first find the width of the storage box using the given volume

V = L * W * H

9 = 4 * W * 3

9 = 12 * W

9/12 = W

W = 3/4 or .75

then with that to find the are of the base multiply the length and the width

a = l * w

a = 4 * 3/4

a = 3

Answer:

5 dollars

Step-by-step explanation:

Given:

The quadratic equation is

[tex]y=6x^2-9x+22[/tex]

To find:

The correct application of the quadratic formula.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]y=6x^2-9x+22[/tex]

Putting [tex]y=0[/tex], we get

[tex]6x^2-9x+22=0[/tex]

Here, [tex]a=6,b=-9,c=22[/tex]. Using the quadratic formula, we get

[tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex]

The correct application of the quadratic formula is [tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex].

Answer:

7

Step-by-step explanation:

Given that these triangles are similar, their sides are in ratio. Let x denote the missing RISE.

Top triangle : bottom triangle

14/8 = x/4

1.75 = x/4

x=7

2674 to the nearest hundred would be 2700

Answer:

A-Cylinder

Step-by-step explanation:

Because when folded back to its original state the circles at the top and bottom act as bottoms of a Cylinder.

Answer:

cylinder which means it's A

three shapes. three areas to find. three areas to add together to find the whole area. gotcha.

Step-by-step explanation:

length is 7 cm and width is 4 cm, so the area is 28 square cm

width is 4 cm and length is 10 cm, so the area is 40 square cm

Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.

base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = 12 square cm

With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).

Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.

28 + 40 + 12

= 80 square cm (ANSWER)

Answer:

Rs 2100

Step-by-step explanation:

SP= 1680

loss percent = 20%

CP=  (SP * 100 ) / ( 100 – percentage loss )

      168000 / 80

     = 2100

I hope im right!!!

Answer:

180°

Step-by-step explanation:

A whole circle is 360°, therefor an straight line is half of that, so 360/2=180.

Answer:

50

Step-by-step explanation:

a right triangle is = to 180 so you need all angles to add to 180 so you take 180 minus it by 90 and 40 you are left with 50 degrees

Answer:

= 0

Step-by-step explanation:

Let's solve your equation step-by-step.

2x−4=2(x−2)

Step 1: Simplify both sides of the equation.

2x−4=2(x−2)

2x+−4=(2)(x)+(2)(−2)(Distribute)

2x+−4=2x+−4

2x−4=2x−4

Step 2: Subtract 2x from both sides.

2x−4−2x=2x−4−2x

−4=−4

Step 3: Add 4 to both sides.

−4+4=−4+4

0=0

Answer:

the base of the given problem is 7

Step-by-step explanation:

The computation of the base in the given problem is shown below:

Given that

20% of 35 boys in the class wear eyeclasses

So if we solve this

The value would be

= 20% of 35 boys

= 20% × 35

= 7

Hence, the base of the given problem is 7

The same would be considered
