Answer:

86

Step-by-step explanation:

This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.

Using proportions, it is found that:

a. The equations are:

b. You would have saved $8 by switching the colors of the dining room and living room.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item a, considering that 5 cans were bought, there are two options:

Hence the equations are given by:

The solution for x is given by:

120 - 24x + 28x = 132

3x = 12

x = 4.

Considering the possible solution, of 4 cans of blue paint and 1 can of white paint.

Exchanging the colors, the price would be of:

4 x 24 + 1 x 28 = 124.

132 - 124 = $8.

You would have saved $8 by switching the colors of the dining room and living room.

Answer:

3 and 4

Step-by-step explanation:

X - 9y = 12     If x=3 and y=-1

3 - (9*-1) = 12

3 +9 = 12

12 = 12

and

X - 9y = 12     If x=0 and y=-4/3

0 - (9 * -4/3) = 12

0 + 12 = 12

Step-by-step explanation:

Cause you notice time is the x and distance (meters) is the y. So 1 minute = 200 meters.

The length of side yz is 15.7 units.

The link between the angles and sides of all kinds of triangles, including acute, obtuse, and right-angle triangles, is known as the law of sines. It asserts that for all sides and angles in a certain triangle, the ratio of a triangle's side length to the sine of an angle opposite that side is the same.

You must know two sides of an angle in a triangle or two sides and an angle across from one of them in order to employ the law of sines. You will discover the law of sines in this article, along with its definition, formula, applications, difficulties, and proof. You will also learn when to employ the rule of sines.

Law of sines is expressed as follows: x/sin X = y/sin Y = c/sin Z.

We have the following:

X = 32°

z = 24

Z = 180 - 32 - 94 = 54°

Substituting the value in x / sin X = y / sin Y = z / sin Z

We get,

x/sin (32) = 24 / sin (54)

x = sin ( 32) × (24) / sin (54)

x ≈ 15.7 units

The length of the side yz is equal to x = 15.7 units.

Answer:

He bought 544 oranges and 1,360 apples

Step-by-step explanation:

Here, we want to know the number of oranges and apples bought

Let the number of oranges be x and the number of apples be y

Looking at their ratios;

x:y = 2:5

so;

x/y = 2/5

2y = 5x ••••••(i)

Now, he lost 3/4 of the apples ( by giving out)

What would be left with him is (1-3/4) = 1/4 * y = 0.25y

What is left with him out if the oranges will be; x-34

So now;

0.25y/x-34 = 2/3

3(0.25y) = 2(x-34) •••••••(ii)

From i, y = 5x/2 = 2.5x

Putting this into ii above, we have

3(0.25)(2.5x) = 2x - 68

1.875x = 2x-68

2x-1.875x = 68

0.125x = 68

x = 68/0.125

x = 544

But y = 2.5x

y = 2.5 * 544 = 1,360

Grace will pay $7 for a student ticket.

Let's write the cost of a student ticket as "S." The price of an adult ticket, according to the information provided, is equal to the cost of a student ticket plus $8. Therefore, this relationship can be expressed as an equation:

Price of adult ticket = Price of student ticket + $8

Since the price of an adult ticket is $15 and the price of a student ticket is "S," the equation becomes:

$15 = S + $8

We now need to separate "S" on one side of the equation in order to figure out how much Grace will pay for a student ticket ("S"). To accomplish this, take $8 away from either side of the equation as follows:

$15 - $8 = S

$7 = S

Answer:

(4.25-1.75)/0.25=10

she bought 10 erasers

Answer:

10 Erasers

Step-by-step explanation:

We can establish the following equation:

TP = NP*PP + NE*EP

Where:

TP = Total price; (4.25)

NP = Number of pencil packages; (1)

PP = Pencil Package's Price; (1.75)

NE = Number of erasers; (What we are looking for)

EP = Erasers Price; (0.25);

Then:

4.25 = 1*1.75 + NE*0.25;

4.25 - 1.75 = NE*0.25;

2.5/0.25 = NE;

10 = NE.

We need to know about translation along vector to solve the probelm. The coordinates of the figure after translation along the vector (5,-4) are (2,-4), (3,0) and (4,-4).

Translation means moving an object from one place to another. Every point on the object moves the same amount of distance and in the same direction. Translation of a point along a vector means moving the point to a different location with respect to the given vector. Here we have three points which form a triangle JKL, we have to translate triangle JKL with respect to the vector (5,-4) to get triangle QRS. Inorder to translate a point along a vector we add the x-coordinate of the vector to the x-coordinate of the point and same for the y-coordinates.

J (-3,0)    Q (-3+5,0-4)≡(2,-4)

K (-2,4)    R (-2+5,4-4)≡(3,0)

L (-1,0)     S (-1+5,0-4)≡(4,-4)

Therefore we get the coordinates of triangle QRS after translation of triangle JKL along vector (5,-4) to be (2,-4), (3,0) and (4,-4)
