Answer:

Step-by-step explanation:

q+n=25

n=25-q

25q+5n=505, using n=25-q in this equation gives you

25q+5(25-q)=505

25q+125-5q=505

20q+125=505

20q=380

q=19

So 19 of the coins are quarters.

Answer:

∠ CFE = 28°

Step-by-step explanation:

∠ CFE and ∠ DFE are adjacent angles and are supplementary, sum to 180°

∠ CFE + 152° = 180° ( subtract 152° from both sides )

∠ CFE = 28°

Adjacent angles share the common side as well as a common vertex (corner point), and they do not overlap. If we decompose the term "adjacent angles".

Adjacent angles:

It's simple, and we see what it means: two angles that are next to each other.Its common side and vertex will be shared by the adjacent angles. If the total of two angles equals 180°, they are said to be supplementary angles. A linear pair is created when two additional angles are next to one another. 180° is equal to the sum of two adjacent supplementary angles.

We have, ∠ EFD = 152°

∠ CFE and ∠ DFE are adjacent angles and are supplementary, summing to 180°

[tex]\therefore[/tex]

∠CFE + ∠EFD = 180° (Linear pair)

∠CFE +152° = 180°

∠CFE= 180°-152°

∠CFE= 28°

This is messy to put into words. Hopefully someone else can clean it up for you.

1 1/3 divided by 4.

Make the 1 1/3 an improper fraction, = 4/3. It may help to think of the whole number, 4, as 4/1.
When dividing fractions, flip the bottom one and then multiply.

So 4/3 over 4/1 becomes
4/3 x 1/4 = 4/12 = 1/3

Answer:

Cost of 1 rose bush = x = $5

Cost of 1 geraniums = y = $2

Step-by-step explanation:

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.

Let us represent:

Cost of 1 rose bush = x

Cost of 1 geraniums = y

DeShawn spent $13 on 1 rose bush and 4 geraniums.

x + 4y = 13..... Equation 1

x = 13 - 4y

Mike spent $56 on 10 rose bushes and 3 geraniums.

10x + 3y = 56....... Equation 2

We substitute 13 - 4y for x in Equation 2

10(13 - 4y) + 3y = 56

130 - 40y + 3y = 56

Collect like terms

- 40y + 3y = 56 - 130

-37y = -74

y = -74/37

y = $2

Solving for x

x = 13 - 4y

x = _13 - 4 × $2

x = $13 - $8

x = $5

Therefore,

Cost of 1 rose bush = x = $5

Cost of 1 geraniums = y = $2

Answer: 2 g/cm^3

Step-by-step explanation:

Remember the relation:

density = mass/volume.

Now, we know that:

Density of metal A = 2.4 g/cm^3

Density of metal B = 1.8 g/cm^3

We know that their masses are combined in the ratio 2:3

Then out of the total mass of metal C, 2 parts are from metal A and 3 parts are from metal B.

Mass of metal C = 60g

mass of metal A = (2/5)*60g =24g

mass of metal B = (3/5)*60g = 36g

Now that we know the mass of each metal, we can find their volumes by:

volume = mass/density

Volume of metal A = (24g)/(2.4g/cm^3) = 10cm^3

Volume of metal B = (36g)/(1.8g/cm^3) = 20cm^3

The total volume of metal C will be equal to the sum of the volumes of metal A and B, then:

Volume of metal C = 10cm^3 + 20cm^3 = 30cm^3

Then we know the volume and weight of metal C, then the density of metal C is:

Density of metal C = (60g)/(30cm^3)= 2 g/cm^3

Answer:

[tex]x = - 3[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

Since y=x+1 plug it into bottom equation as y.

[tex]x + 1= 5x + 13[/tex]

Subtract 1 from both sides

[tex]x = 5x + 12[/tex]

Subtract 5x from both sides

[tex] - 4x = 12[/tex]

Divide both sides by -4

[tex]x = - 3[/tex]

Now x=-3 into the top equation to find y

[tex] - 3 + 1 = - 2[/tex]

The answer would be:

y = 5

x = 4

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

5x+3y=35;2x+4y=28

Step: Solve 5x+3y=35 for x:

5x+3y=35

5x+3y+−3y=35+−3y(Add -3y to both sides)

5x=−3y+35

5x/5=−3y+35/5 (Divide both sides by 5)

Step: Substitute −3/5y+7 for x in 2x+4y=28:

2x+4y=28

2(−3/5y+7)+4y=28

14/5y+14=28 (Simplify both sides of the equation)

14/5y+14+−14=28+−14 (Add -14 to both sides)

14/5y=14

14/5y/14/5=14/14/5

(Divide both sides by 14/5)

y=5

Step: Substitute 5 for y in x=−3/5y+7:

x=−3/5y+7

x=−3/5(5)+7

x=4 (Simplify both sides of the equation)

Answer:

x=4 and y=5

Answer:

Taller because it is bigger and more likely to have greater volume

Step-by-step explanation:

its correct 100%

The correct statement is,

''The taller cylinder have the larger volume than shorter cylinder.''

What is an expression?

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

Given that;

Will the shorter cylinder or taller cylinder have the larger volume.

Since, We know that;

The volume of a cylinder is calculated by multiplying the area of the base by the height.

And, since the height of the taller cylinder is greater than the shorter cylinder, it is likely to have a larger volume.

Thus, The taller cylinder have the larger volume than shorter cylinder.

Answer:

-2

Step-by-step explanation: theres no image so i cant tell for sure but if it is rotating counterclockwise then that means its negative.

The coordinates of the image of point Y after these transformations is -2. The figure givenhas been translated up two units and turned 180 degrees counterclockwise.

How do we find the Cartesian coordinate plane?

The Cartesian coordinate plane is an endless two-dimensional plane. On an endless 2d plane, any two-dimensional figure may be drawn. A location is assigned to each point in a Cartesian plane.

The figure givenhas been translated up two units and turned 180 degrees counterclockwise.

After these changes, the coordinates of the image of point Y are -2.

Hence, the coordinates of the image of point Y after t, These transformations is -2.

Step-by-step explanation:

Similar triangles may or may not be congruent.

The value of h is 6.

The equivalent ratio of the triangles is:

[tex]\mathbf{h : 12 = 3 : h}[/tex]

Express as fractions

[tex]\mathbf{\frac{h }{ 12} = \frac{3 }{ h}}[/tex]

Cross multiply

[tex]\mathbf{h^2=36}[/tex]

Take positive square roots of both sides

Answer:

-1,050

Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.

Answer:

The answer is -1,050.

Step-by-step explanation:

An equation to represent the relationship between the submarines elevation & time would be y=-1,050x. Since we know that in two hours the submarine can reach 2,100 feet below the surface we need to figure out how long the submarine can reach in 1 hour. So we do 2,100/2 which equals 1,050. And since the submarine going below, it turns into -1,050.

Answer:

A translation moves every point of a figure or a space by the same amount in a given direction. The reflection of a red shape against an axis followed by a reflection of the resulting green shape against a second axis parallel to the first one results in a total motion which is a translation of the red shape to the position of the blue shape.
