Step-by-step explanation:

16 cows : 4 sheep

? cows : 48 sheep

48 / 4 = 12

16 x 12 = 192

Answer:

192 Cows

Step-by-step explanation:

if the ratio is 1 sheep: 4 cows then by multiplying 48 by 4 you get a total of 192 cows

Answer:

4.0 meters, ∠C = 39°, ∠A = 51°

Step-by-step explanation:

Firstly, our diagram shows us that the given triangle is actually a right triangle. So we can use the Pythagorean Theorem to solve for the height of the chain:

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex](3.3)^{2} +b^{2} =(5.2)^{2}[/tex]

[tex]b^{2} =(5.2)^{2}-(3.3)^{2}[/tex]

[tex]b =\sqrt{(5.2)^{2}-(3.3)^{2}}[/tex]

[tex]b=4.0187...[/tex]

[tex]b=4.0 m[/tex]

Now, we can use the Law of Cosines to figure out one of the acute angles:

[tex]c^{2} =a^{2} +b^{2} -2ab(cos(C))[/tex]

[tex](3.3)^{2} =(4.0)^{2} +(5.2)^{2} -2(4.0)(5.2)(cos(C))[/tex]

[tex]cos(C)=\frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)}[/tex]

[tex]C=cos^{-1}( \frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)})[/tex]

[tex]C=39.3915...[/tex]

∠C = 39°

And since we know that all angles in a triangle add up to 180°:

∠A + ∠B + ∠C = 180

∠A + 90 + 39 = 180

∠A = 180 - 90 - 39

∠A = 51°

However, you should always review any answers on the Internet and make sure they are correct! Check my work to see if I made any mistakes!

Answer:

m < 32

Step-by-step explanation:

m/8 < 4

m < 32

Answer:

m<32

Step-by-step explanation:

multiply both sides of the inequality by 8

[tex]8 \times \frac{m}{8} < 8 \times 4[/tex]

then, reduce the numbers with the GCF= 8

[tex]m < 8 \times 4[/tex]

Answer:

Yes; SSS;Triangle AYM Triangle EDC The answer will be D is the correct answer choice.

Step-by-step explanation:

Answer:

1.) The product of 12 and 3/4 is less than 12. This is because you are multiplying 12 by a number less than 1.

2.) The product of 5 and 1/2  is less than 5, this is because you are multiplying 5 by a number less than one.

Step-by-step explanation:

If multiplied by a number less than one then it will be smaller than original

If multiplied by one will be the same as original

If multiplied by a number greater than one it will be greater than original

your answer would be 33.

step 1

2(+14)−1(2−5)

2+28−1(2−5)

step 2 distribute

2+28−1(2−5)

2+28−2+5

step 3 then add the numbers

2+28−2+5

2+33−2

combine

2+33−2

ANSWER IS

For 7 dozens cookies 3 1/2 cups needed.

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

Given:

For 3 dozen cookies = 1 1/2 cups = 3/2 cups

For 1 dozen cookies = 3/2 * 1/3 = 1/2 cups needed

So, for 7 dozen cookies = 1/2 * 7

                                       = 3 1/2 cups needed

Hence, for 7 dozens cookies 3 1/2 cups needed.

Answer: 3.4

Step-by-step explanation: 6-2 is 4 and 7-4=3 therefore it’s 3.4

The solution is 3.4

The value of the equation 4.2 less than 7.6 is 3.4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is expressed as

A = 4.2 less than 7.6

Substituting the values in the equation , we get

A = 7.6 - 4.2   be equation (1)

On simplifying the equation , we get

The value of A = 7.6 - 4.2

The value of A = 3.4

Therefore , the value of A is 3.4

Hence , The value of the equation 4.2 less than 7.6 is 3.4

Step-by-step explanation:

Find the mean of the data set shown below. Round to the nearest tenth, if necessary.

This Week's High Temperatures (°F)

29, 38, 45, 31, 50, 58, 62

The formula for the Mean of a given set of data is

= Sum of terms/ Number of terms

Number of terms = 7

Hence,

Mean = 29+ 38+ 45+ 31+ 50+ 58+ 62/7

Mean = 44.714285714286

The required actual length of the train is given as 27 ft.

Given that,
Heather drew the scaled drawing of a train car shown below. She used the scale of 2 cm = 5 ft to complete the drawing.

The scale factor is defined as the ratio of the modified change in length to the original length.

here,
As given,
2 cm = 5 ft
1 cm = 5/2 ft
Tain car length = 10.8 m
Actual length = 10.8 × 5/2 = 27 ft

Thus, the required actual length of the train is given as 27 ft.
