3) Daniel bought a magazine for $7 and four
erasers. He spent a total of $19. How
much did cach craser cost?

Answer: 7

To maximize the length of the third side, which I'll call x, it needs to be one of the two shorter sides.

So by the triangle inequality theorem, 6+x>12 meaning the minimum whole number value of x is 7.

Answer:

[tex]g(x)= (x-10)^2[/tex]

Step-by-step explanation:

g(x) = [tex](x-10)^{2}[/tex] is the translation 10 units right of f(x) = [tex]x^{2}[/tex].

Translation means the displacement of a figure or a shape from one place to another.

g(x) = [tex](x-10)^{2}[/tex] where a = 1, h = 10 and k = 0.

Answer:

a=12      b=25 degrees

Step-by-step explanation:

the tangent of the 25 degree angle gets you your answer

Trigonometry ('triangle', or 'measure') is the branch of mathematics that studies relationships between side lengths or the angles of the triangles

by the question, we have the following parameters:

Vertical Leg = x

Base length = 12

Angle at the vertical side = 25 degrees

The measure of the x is then calculated using the following tangent ratio

tan(x) = Base length / Vertical leg

Substitute known values

tan(x) = 12/x

So, the trigonometric expression that it is be used for find the value of x is tan(x) = 12/x

Answer:

9

Step-by-step explanation:

5 times 5 = 25

45 divided by 5 = 9

Step-by-step explanation:

Because there is a negative sign before parentheses.

The sign( a) is negative When multiplied by the negative before the parentheses The sign becomes negative

Hey there!

First, let's solve this maths problem:

7a-(3+8a)

Here we should use the Distributive Property and distribute -

Wait, what? Distribute a minus? Yeah! The minus sign (in this case) is the same as -1:

7a-3-8a

Now, why did the plus sign change to the minus sign?

Because a negative times a positive is a negative.

Answer: The calculation is correct.

Step-by-step explanation:

If Hernando ate 2/8 of a pizza for a dinner, the remaining pizza will be:

= 1 - 2/8

= 6/8

If he gave his 6 friends the rest of the pizza and told them to share it equally, each person will get:

= 6/8 ÷ 6

= 6/8 × 1/6

= 1/8

Each person will get 1/8 each

Since he also concluded that each person received 1/8 of the whole pizza, Hernandos calculations are correct

Answer:

127.3 feet.

Step-by-step explanation:

The line from first base to third base is the hypotenuse of a right triangle, with the right angle at home base.

Since this is a right triangle, we will use the Pythagorean Theorem to find the hypotenuse.

So, let a = one side and let b = the other side of the right triangle. And, let c = the hypotenuse.

The Pythagorean Theorem is:

c^2 = a^2 + b^2.

So, c= sqrt(a^2 + b^2)

And we have: c= sqrt(90^2 + 90^2)

= sqrt(8100 + 8100) = sqrt(16,200)

= 127.3 ft.

Conclusion: The distance from first base to third base is 127.3 ft, (approximately).

What is the table?

Answer:

The distance is approximately 3.6

Step-by-step explanation:

The distance from a point (xo, yo) to a line ax+by+c=0 is the shortest distance from the given point to any point on the line.

It can be calculated with the formula:

[tex]\displaystyle d={\frac {\mid ax_{0}+by_{0}+c\mid}{\sqrt {a^{2}+b^{2}}}}[/tex]

The coordinates of point A are (1,-2). The equation of the line must be found by knowing two clear points it passes through.

These points are (0,3) and (6,-1). First, we calculate the slope:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle m=\frac{-1-3}{6-0}=\frac{-4}{6}=-\frac{2}{3}[/tex]

The equation of the line in slope-point form is:

[tex]y=m(x-x_o)+y_o[/tex]

Taking the point (0,3) and the slope above:

[tex]\displaystyle y=-\frac{2}{3}(x-0)+3[/tex]

Multiply by 3:

[tex]3y=-2x+9[/tex]

Moving all terms to the left side:

[tex]2x+3y-9=0[/tex]

We now have all the required values to calculate the distance:

a=2, b=3, c=-9, xo=1, yo=-2

[tex]\displaystyle d={\frac {\mid 2\cdot 1+3\cdot (-2)+(-9)\mid}{\sqrt {2^{2}+3^{2}}}}[/tex]

[tex]\displaystyle d={\frac {\mid 2-6-9\mid}{\sqrt {13}}}\approx 3.61[/tex]

The distance is approximately 3.6

The sample in the table is used to show the preference of each student

156 students preferred country music

From the question, we have:

Country = 6

Total students = 650

Total proportion = 25 i.e. 12 + 7 + 6

So, the number of students that preferred country music is:

Country = 6/25 * 650

Evaluate the product

Country = 156

Hence, 156 students preferred country music

Replace y = -4x into y = 3x + 28

-4x = 3x + 28

Minus both side by 3x

-7x = 28

x = -4

Recheck : - 4 x (-4) = 3 x (-4) + 28
16 = -12 +28 = 16 (t)

Answer:

(- 4, 16 )

Step-by-step explanation:

y = 3x + 28 → (1)

y = - 4x → (2)

substitute y = 3x + 28 into (2)

3x + 28 = - 4x ( add 4x to both sides )

7x + 28 = 0 ( subtract 28 from both sides )

7x = - 28 ( divide both sides by 7 )

x = - 4

substitute x = - 4 into (2)

y = - 4(- 4) = 16

solution is (- 4, 16 )

Answer: The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature.

Bee larvae have been shown to be an excellent food source for rearing insects

Silk worm larvae is used in extracting silk and thus help in making clothes.

Bee larvae is used in pest control.

The silkworms feed solely on large amounts of leaves from the mulberry tree for around 30-40 days

The majority of honey bee larvae eat honey, but larvae that are chosen to become future queens will be fed with royal jelly.
