Answer: 63

Step-by-step explanation:

14.5x1.5=21.75

15x2.75=41.25

21.75+41.25=63

Answer:

90°

Step-by-step explanation:

There is no work. We know the right angle in the triangle and  the x are supplementary. Meaning, they add up to 180 degrees.  Therefore, 180-90 = 90. Think of it as a full triangle. If the 40 at the top was not half, but a full triangle, the 40 at the top would become 80. The 50 in the bottom left would mean there would be a 50 in the bottom right when you mirror the triangle. Therefore, you also need x to be 90 to make it a right triangle.

Answer:

(-6, 8)

Step-by-step explanation:

Since the radius is 10 units and the center is on the origin of the circle, the distance from the origin to the point (-6, y) must be 10.

We can use the distance formula given by:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

We will let the point (-6, y) be (x₂, y₂) and the origin point (0, 0) be (x₁, y₁). The distance is 10. Substitute:

[tex]10=\sqrt{((-6)-(0))^2+((y)-(0))^2}[/tex]

Simplify:

[tex]10=\sqrt{(-6)^2+(y)^2}[/tex]

Square both sides and simplify:

[tex]100=36+y^2[/tex]

Solve for y:

[tex]y^2=64[/tex]

Take the square root of both sides:

[tex]y=\pm\sqrt{64}=\pm 8[/tex]

Since our point is in QII, y must be positive. Hence, we will use the positive case. So, y = 8.

Our point is (-6, 8).

Answer:

2/7

Step-by-step explanation:

Answer:

5/12

Step-by-step explanation:

All the beans are equally likely to be chosen, so the bottom (denominator) of the fraction is 12 (there are 12 beans in the box).

The numerator is 5 because that's the number of red beans in the box.

Answer:

The price of T-shirts before the sale = 42 euros

The price of scarves before the sale = -77/2 euros

Step-by-step explanation:

The cost of the items Zina buys from the store initially are;

Two scarves and three T-shirts for 49 euros

The reduction in the price of scarves a week later during sales = 1.5 euros

The reduction in the price of T-shirts a week later during sales = 2 euros

The items Zina bought for 40 euros at the reduced price of the sales opportunity are;

Four scarves and five T-shirts for 40 euros

Let 'x' represent the initial price of a scarf and let 'y' represent the initial price of a T-shirt, we  have;

2·x + 3·y = 49...(1)

4·(x - 1.5) + 5·(y - 2) = 40...(2)

Expanding equation (2) gives;

4·x - 6 + 5·y - 10 = 40

4·x + 5·y = 40 + 6 + 10 = 56

∴ 4·x + 5·y = 56...(3)

By multiplying equation (1) by 2 and subtracting the result from equation (3), we get;

4·x + 5·y - 2 × (2·x + 3·y) = 56 - 2 × 49 = -63

-y = -42

y = 42

The price of T-shirts before the sale = 42 euros

x = (49 - 3 × 42)/2 = -77/2

x = -77/2

The price of scarves before the sale = -77/2 euros

(However, if the had bought the 4 scarves and 5 T-shirts during sales at 70 euros, we get;

The price of T-shirts before the sale = 12 euros

The price of scarves before the sale = 6.5 euros.

The allowable total price for the reduced 4 scarves and 5 T-shirts is between 66 and about 82 for both initial prices to be +ve)

Answer:

x=-4

Step-by-step explanation:

The axis of symmetry is the x-value where the two “curves” of the parabola start at. For this parabola, the curves start at x=-4 and extend outward. So, the axis of symmetry is x=-4.

Answer:

x = -4

Step-by-step explanation:

The axis of symmetry is a vertical line thru the vertex.  The vertex is (-4, 2).

So, the line of symmetry is x = -4

Answer:

Tn = 3n + 1

Step-by-step explanation:

The given sequence 2,5,8,11,14 is an arithmetic sequence

The nth term of an arithmetic sequence is expressed as;

Tn = a + (n-1)d

a is the first term

d is the common difference

n is the number of terms

Given

a = 2

d = 5-2 = 8-5 = 3

Substitute into the formula

Tn = 2 + (n-1) * 3

Tn = 2 + 3n - 3

Tn = 3n + 1

This gives the term rule for the sequence  

17Answer:

Step-by-step explanation:

The area of ΔNOP is approximately 2.11 square centimeters, rounded to the nearest 10th of a square centimeter.

Suppose the vertices of the considered triangle ABC are on A(A_x,A_y), B(B_x,B_y), C(C_x,C_y), then, the area of the triangle is given by:

[tex]Area = \dfrac{|A_x(B_y-C_y) + B_x(C_y-A_y) + C_x(A_y-B_y)|}{2}[/tex]

We are given that;

Side P=2.5cm

Side N=2.3cm

Angle O=71

Now, to find the area of a triangle, we can use the formula:

A = (1/2) * base * height

where base and height are two sides of the triangle that form a right angle, or any two sides of the triangle if we know the included angle between them.

In this case, we are given the lengths of two sides, p and n, and the measure of one angle, ∠O. To find the area, we need to first find the length of the third side, OP, using the Law of Cosines:

OP² = p² + n² - 2pn cos(∠O)

OP² = 2.5² + 2.3² - 2(2.5)(2.3) cos(71°)

OP² = 4.2694

OP ≈ 2.067 cm

Now we can use the formula for the area of a triangle:

A = (1/2) * OP * n * sin(∠O)

A = (1/2) * 2.067 * 2.3 * sin(71°)

A ≈ 2.11 cm²

Therefore, the area of triangle NOP will be  2.11 square centimeter.

Answer:

f(5)=11

Step-by-step explanation:

f(x)=4x-9

f(5)=4(5)-9

f(5)=20-9

f(5)=11

Answer:

f(5) = 11

Step-by-step explanation:

F(x) = 4x - 9 for f(5)

x gets replaced with 5

f(5) = 4(5) - 9

f(5) = 20 - 9

f(5) = 11
