Answer:

45

Step-by-step explanation:

60/4 = 15

15 x 3 = 45

Answer:

45 dogs

Step-by-step explanation:

to figure this out we divide the ratio of total cats the the simplified ratio

(60 divided by 4 = 15)

to find out the dogs, multiply that base number, 15, into 3

(3 x 15 = 45)

the new ratio would be 60:45

hope this helped

Answer:

180 units^3

Step-by-step explanation:

Formula for the volume of a right triangular prism: V=1/3Ah (A=Area of base triangle, h=height)

BASE TRIANGLE

A= 1/2bh (base•height)

A= 1/2•10•4

A= 40 units^2

VOLUME OF PRISM

V=1/3Ah

V= 1/3•40•18

V= 180 units cubed

Hope this helps! Let me know if I'm off by anything.

Answer:

89°

Step-by-step explanation:

Total inner degree of PQRS = (4-2)*180° = 360°

PST is a straight line : 180°

angle PSR = 180-128

=52°

angle RQP + angle QPS = 360 - 52 - 130 = 178°

Angle PQR = Angle QPS

Angle QPS = 178/2 = 89°

Answer:

C. –x + 8y = 56

Step-by-step explanation:

Write in standard form.

x  −  8 y  =  − 56

This is a linear function in the slope - intercept form:

y = m x + b and we need a standard form:

a x + b y = c

y = 1/8 x + 7   / * 8 ( we will multiply both sides of equation by 8 )

8 y = x + 56

- x + 8 y = 56  / * ( - 1 )

x - 8 y = - 56

The equation is  y = 1/8x + 7

Standard form equation is Ax + By = C,  where A > = 0.

First eliminate the fractions by multiplying the equation by 8

8y = x + 56

Subtract x from each side

-x + 8y = 56

SInce x coeficient can't be negative multiply the equation by negative one.

x - 8y = -56

Answer:

The size of the sample 'n' = 2401

Step-by-step explanation:

Step:1

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

              [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

we know that the proportion

               [tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]

Step:2

The margin of error is determined by

              [tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]

              [tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

Final answer:-

The size of the sample 'n' = 2401

Answer: jacob is right

Step-by-step explanation:

each face in a cube is equal, and we know that there are six sides on a cube

this means that we need to find the surface area of one side and multiply it by six to see if jacob is correct

to find the area of one side you would do

a = Lw

a = 10 * 10

a = 100

so one face equals 100 cm^2 so 100 * 6 = 600

600 is less than 1000 so jacob is correct

Answer:

8   =     D

9 = D

10 = D

Step-by-step explanation:

For 8, a straight line is 180 degrees, and if PQS is already x+55, then RQS is also x, so it would be 2x +55 = 180

For 9, surface area is just area of the sides of a shape, so (3*15)*2 + (6*3)*2 + (5*6)*2 which equals 30 +36 + 60, which is 126.

For 10, the volume is the width*length*height, so 4*4*11 = 16*11 = 176, and because there are 6 rectangular prisms, 176*6 which is equal to 1056.

Answer:

  50.27 cm²

Step-by-step explanation:

The 40° sector represents 40°/360° = 1/9 of the area of the circle. So, the sector area is ...

  A = (1/9)πr² = (π/9)(12 cm)² = 16π cm² ≈ 50.27 cm²

Answer:

7x - 1/9

Step-by-step explanation:

2/3 (6x - 1/6) + 3x

12x/3 - 2/18 + 3x

4x - 1/9 + 3x

7x - 1/9

After simplifying, the value of expression is,

⇒ 7x - 1/9

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ 2/3 (6x - 1/6) + 3x

Now, We can solve the expression as;

⇒ 2/3 (6x - 1/6) + 3x

⇒ 2/3 × 6x - 2/3 × 1/6 + 3x

⇒ 4x - 1/9 + 3x

⇒ 7x - 1/9

Step-by-step explanation:

Answer:

20 waves

Step-by-step explanation:

Out of 50 waves, Mark will catch 20 waves. To find this, first, you have to put it into a ratio.

8        x

---  =  -----

20      50

To solve this, you need to multiply 8 x 50, which is 400. Next you need to divide 400 by 20, which is 20 waves.

This means x = 20 waves.

Answer:

(x,y)↦ ( x + 1 ) , ( y + 9 )

scale factor 2  

Step-by-step explanation:

Step 1 identify the translation.

To do this we find the center of ⨀T and the center of ⨀T' and find the difference between their x and y values.

The center of ⨀T is at ( -1 , -7 )

The center of ⨀T' is at ( 0 , 2 )

we now find the difference between the x and y values. ( note that you must subtract the x and y values from the preimage from the translated image to get the correct translation. )

For the x values: 0 - ( - 1 ) = + 1

For the y values:  2 - ( -7 ) = + 9

So translation was (x,y)↦ ( x + 1 ) , ( y + 9 )

step 2 Find the scale factor

We can identify the scale factor by dividing the radius of the preimage by the radius of the dilated image.

The radius can be identified by finding the distance between the center and any point on the circle

The radius of the preimage is 3

The radius of the dilated image is 6

So scale factor = 6 / 3 or 2

Hey love! <3

Answer:

Your answer is 306 units^2!

Step-by-step explanation:

Let's work this out together!

First let's find the top and bottom square's area.

6 x 15 = 90

Since there are not only two of those shapes but THREE, 90 x 3= 270.

So 270 is the surface area of the middle rectangles.

Step 2! Let's find the area of these triangles. We know that both of the triangles are 6 on each side.

Think back to geometry formulas. The formula for finding the area of a triangle is different then a square.

Triangle formula: Base x Height / 2 = A

Rectangle formula: Base x Height = A

So 6 x 6 is 36, now we have to divide it by two; which equals 18.

Since there are TWO triangles, we multiply 18 by two giving us the total surface area of the triangles, 36.

Now let's add our products together!

36 + 270 = 306

Thus the total surface area being 306 units^2

Answer:

He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours

Step-by-step explanation:

Justin likes to get 7 hours of sleep.

He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins

Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.

1 hour = 60 minutes

1/3 hours = 60/3 = 20 minutes

Hours         Minutes

7                     00       when we borrow 1 hour we borrow 60 minutes

5                    20

1                   40

He needs 1 hour 40 minutes more to get the amount of sleep he likes

or 1 2/3 hours

Answer:

It looks like C is the correct answer xd

Answer:

27000 J

Step-by-step explanation:

The specific heat equation is: Q = mC∆T

Q is the energy in Joules.

m is the mass in grams of the substance.

C is the specific heat capacity.

∆T is the change in temperature.

Let's plug in what we know.

Q = 3000(0.9)(10)

Q = 27000 J
