Answer:

when x = 3 1/3, y = 4.5

or

when x =3 , y = 5

Step-by-step explanation:

Here, we want to solve using substitution

xy = 15

let x = 15/y

Put this into the first equation;

3(15/y) + 2y = 19

45/y + 2y = 19

Multiply through by y

45 + 2y^2 = 19y

2y^2 -19y + 45 = 0

2y^2 - 10y - 9y + 45 = 0

2y(y-5) -9(y-5) = 0

(2y-9)(y-5) = 0

2y-9 = 0

or y-5 = 0

2y = 9 or y = 5

y = 9/2 or y = 5

y = 4.5 or y = 5

Recall;

x = 15/y

x = 15/4.5 or x = 15/5

x = 3 1/3 or x = 3

Mrs. Rodrigues should use Standard deviation.

The correct option is b.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Given:

Mrs. Rodrigues wants to compare the spread of the test scores of her two biology classes.

From the given choices:

The measures of spread include:

Range, quartiles, interquartile range, variance and standard deviation.

Standard deviation is the appropriate choice.

Therefore, standard deviation is the correct phrase.

Answer:

181cm²

Step-by-step explanation:

Given

Radius of a circle = 7.6cm

Area of the circle = \pi r²

Substitute

Area of the circle = 3.14(7.6)²

Area of the circle  = 3.14(57.76)

Area of the circle = 181.3664cm²

Area of the circle to 3sf is 181cm²

Note: Consider the dependent variable is T instead of I, and we need to find the value of T when x=5 and y=-7.

Given:

[tex]T=3x+4y[/tex]

To find:

The value of T when x=5 and y=-7.

Solution:

We have,

[tex]T=3x+4y[/tex]

Putting x=5 and y=-7, we get

[tex]T=3(5)+4(-7)[/tex]

[tex]T=15-28[/tex]

[tex]T=-13[/tex]

Therefore, the value of T is -13 when x=5 and y=-7.

Answer:

Step-by-step explanation:

f(2) = -2^2 + 2 + 14 = -4 + 2 + 14 = 12

Answer:

f(2) = 20

Step-by-step explanation:

f(x) = -x^2 + x + 14

f(2) = (2)^2 + (2) + 14

f(2) = 4 + 2 + 14

f(2) = 20

The name of the shape in the figure is a hexagon.

A polygon is often a plane figure in geometry that is enclosed by a closed chain made up of a finite number of straight-line segments that end in a loop. The spots where two of these segments meet are referred to as the polygon's vertices (plural: vertices) or corners. These segments are known as its edges or sides.

Given a shape,

the shape is a polygon,

to name a polygon first count the number of sides of the figure,

as we count there are 6 sides for the shape,

There are some specific names for the shapes according to their number of sides, like

Number of Sides Name          

3                      Triangle                    

4                 Quadrilateral

5                    Pentagon

6                     Hexagon

The name for the shape is Hexagon.

Hence the name of the figure is Hexagon.

CHECK THE ATTACHMENT FOR THE FIQURE OF THE QUESTION

✓We were given the dimension of the rectangular prism as 10cm × 4cm × 4cm,

✓The cross section of the paperweight can be cut into half to it's base. Then the new dimension will be 4cm × 4cm which is a quadrilateral.

✓ Then width= 4cm, and height=4 cm are of the same values, hence the shape it forms is a SQUARE. and also the their angles is 90° each.

Answer:

x = 26.4

Step-by-step explanation:

Here, we want to get the value of x

To get this, we are to use the appropriate trigonometric ratio

From the question, we have the opposite and the adjacent

The trigonometric ratio to use in this case is the tangent

Mathematically;

Tan 53 = 35/x

x = 35/tan 53

x = 26.37

which is 26.4

Answer: William's is 16:4 and Tracey's are 15:5

Step-by-step explanation:

Answer:

31

Step-by-step explanation:

Answer:

the answer to your question would be 44

Answer:

The possible coins are:

P = penny = $0.01

N = nickel = $0.05

D = dime = $0.10

Q = quarter = $0.25

H = half dollar = $0.50

We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)

Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X

We know that Adam has half as much money as Ben, this can be written as:

(A + B + C) = 3*X/2

The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.

For example, if X = $0.10

then:

(A + B + C) = $0.10*(3/2) = $0.15

We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.

if x = $0.50 then:

(A + B + C) = (3/2)*$0.50 = $0.75

Here we could have:

A = $0.50

B = $0.25

then: A + B = $0.75

But we still have the coin C.

If we take X = $0.25 then:

(A + B + C) = (3/2)*$0.25 = $0.375

We could round the right part to $0.40

then the coins in the left part would be:

A = $0.25

B = $0.10

C = $0.05

A + B + C =  $0.25 + $0.10 +  $0.05 = $0.40

This is a strech, but is the only thing we can make with the given problem.

Answer:

There's 2.5

Step-by-step explanation:

4 cups is equal to 1 quart

So that means 8 cups is equal to 2 quarts

If we add 2 more cups then we would add 0.5 more quarts.

This means that 10 cups is 2.5 quarts.

Answer:

2.5 quarts

Step-by-step explanation:

since there are 0.25 quarts in one cup. you have to multiply 2.5 by 10. hope this helps*

Step-by-step explanation:

Answer:

Look below!

Step-by-step explanation:

Angle A = 180-47 = 133

Angle B = 180-32-Angle A = 180-32-47 = 101

Angle D = 90-32 = 58

Angle C = 180-47-58 = 75

Hope I helped!

Answer:

A=133 ,B=15, C=75  D= 58

Step-by-step explanation:

Angle 32, d, and right angle add up to 180. So 180=32+90+x. Then x = 58 (D). The all 3 angles in the triangle add up too 180 so 180=47+58+x. x=75 (C). The 47 and a equal to 180 degrees. 180-47=133. The 133+32+x=180. x=15 (B).
