Answer:

x=9

Step-by-step explanation:

48-3=45

5x=45

45/5=9

The value of x in the given inequality will be equal or smaller than 9,

x ≤ 9

A relationship between two expressions or values that are not equal to each other is called inequality.

Given is an inequality 5x + 3 ≥ 48

Solving for x,

5x + 3 ≥ 48

Subtract 3 from both side, that will reverse the sign,

5x ≤ 45

Divide both sides by 5,

x ≤ 9

Hence, the value of x will be equal or smaller than 9, x ≤ 9

Step-by-step explanation:

Answer:

150°

Step-by-step explanation:

It's opposite angles so we need to do:

Angle F to B = angle G to A

130+20 = 150°

We have been given that the quadratic equation [tex]y=-0.5x^2+4x+10[/tex] models the path of a heavy ball through the air, where y represents the height in feet and x represents time in seconds. We are asked to find the time when ball will hit the ground.

The ball will hit the ground, when height of ball above ground will be 0. So we will equate our given quadratic equation with 0 and solve for x.

[tex]-0.5x^2+4x+10=0[/tex]

We will use quadratic formula to solve our given problem.

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex], where

b = Coefficient of x term,

a = Coefficient of [tex]x^2[/tex] term,

c = Constant.

[tex]x=\frac{-4\pm\sqrt{(-4)^2-4(-0.5)(10)}}{2(-0.5)}[/tex]

[tex]x=\frac{-4\pm\sqrt{(16+20}}{-1}[/tex]

[tex]x=\frac{-4\pm\sqrt{36}}{-1}[/tex]

[tex]x=\frac{-4\pm6}{-1}[/tex]

[tex]x=\frac{-4+6}{-1}, x=\frac{-4-6}{-1}[/tex]

[tex]x=\frac{2}{-1}, x=\frac{-10}{-1}[/tex]

[tex]x=-2,x=10[/tex]

Since time cannot be negative, therefore, the ball will hit the ground after 10 seconds.

Step-by-step explanation:

1) x - 1 = - 11

x = - 11 + 1

x = - 10

2) 9k = 54

k = 54/9

k = 6

3) 14 + r = 16

r = 16 - 14

r = 2

Answer:

Step-by-step explanation:

9^2/9^7= 1/9^(7-2) = 1/9^5

Step-by-step explanation:

The area of a parallelogram is b * h, where b is the base and h is the height. We'll call the height x and the base x + 4, and we know that this is equal to 45.

x (x + 4) = 45

x² + 4x = 45

x² + 4x - 45 = 0

(x + 5)(x - 4) = 0

x = -5, 4 → x = 4 (no negative sides)

Therefore, base is 8 and height is 4. Hope this helps!

Answer:

Volume = 9900 ft2

Step-by-step explanation:

To find the volume of the pool, we can use the base as the trapezoid, and then we need to calculate the base area and multiply by the height.

The trapezoid has a bigger base of 8 and a smaller base of 3, with a height of 60, so the area is:

Area = (8+3)*60/2 = 330 ft2

Now, to find the volume, we just need to multiply the base area by the height of 30 feet:

Volume = Area * Height = 330 * 30 = 9900 ft2

Step-by-step explanation:

[tex][\left(-5\right)-\frac{9}{\left(-3\right)^3}]\left(-6\right)+\left(-6\right)[/tex]

Remove parenthesis: [tex](-a)=-a[/tex]

[tex]=-[-5-\frac{9}{\left(-3\right)^3}] * 6-6[/tex]

[tex][-5-\frac{9}{\left(-3\right)^3}]*6 = -28[/tex]

[tex]= - (-28) - 6[/tex]

Apply rule: [tex]- (-a) = a[/tex]

[tex]= 28 - 6[/tex]

Subtract the numbers: [tex]28 - 6 = 22[/tex]

Final answer:

[tex]= 22[/tex]

Answer:

Step-by-step explanation:

How many minutes did Betty practice?:

36 x 7=252

How many minutes in all did Jake and Betty practice?:

252+36=288

Equation:

1:7

The equations can be modeled as:

Betty = 252 minutes

Jake + Betty = 288 minutes.

Two or more expressions with an equal sign are defined as an equation.

Given that, Jake practiced piano for 36 minutes and Betty practiced for 7 times as long as Jake.

Therefore, Betty practiced for:

36 × 7 minutes

= 252 minutes.

The total time of practice is:

252 + 36

= 288 minutes.

The equations can be modeled as:

Betty = 252 minutes

Jake + Betty = 288 minutes.

Answer:

An inscribed angle is defined as the half of its intercepted arc. It's important to notice that the subtended arc by angle C is 180°, because it's have of the total arc length.

[tex]C=\frac{1}{2} (180\°)=90\°[/tex]

Therefore, angle C is a right angle.

Now, in the image attached you can notice that triangle ABC has one acute angle of 46° and one right angle. We already know that the sum of all three internal angles of a triangle must be equal to 180°.

[tex]90\° + 46\° + B=180\°\\B=180\° - 46\° - 90\° = 44\°[/tex]

On the other hand, notice that the diameter of the circle represents the hypothenuse for the right triangle. To find the hypothenuse, we need to know the length of one leg at least.

Therefore, there's no enough information to find the hypothenuse, which implies we can't find the diameter/radius.

1 / 663

Step-by-step explanation:

First, let's find the total number of ways you can pick 2 cards from the deck. This is 52 * 51 = 2652 because there are 52 cards available for your first pick, and after you pick one, you'll have 51 left for your second pick.

There are 4 5's  (one for every suite) and only 1 Queen of Hearts in a deck of cards. Therefore, the total number of successful outcomes will be 4 * 1 = 4.

The probability of picking a 5 and then a Queen of Hearts is 4 / 2652 =

Answer:

283.5 cm squared

Step-by-step explanation:

The surface area of a solid is basically just the sum of the areas of all the exterior sides. In this figure, we have 3 congruent triangles at the top, 3 congruent rectangles on the sides, and 1 triangle at the base. We need to find all these areas.

3 congruent triangles:

The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Here, the base of one triangle is 10 and the height is 4. So:

A = (1/2) * b * h

A = (1/2) * 10 * 4 = 20

Since there are 3 such triangles, multiply 20 by 3:

20 * 3 = 60 cm squared

3 congruent rectangles:

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the length is 6 and the width is 10, so:

A = lw

A = 6 * 10 = 60

There are 3 such rectangles, so multiply 60 by 3:

60 * 3 = 180 cm squared

1 base triangle:

Again we use the formula A = (1/2) * b * h for this area.

Here, the base is 10 and the height is 8.7, so:

A = (1/2) * b * h

A = (1/2) * 10 * 8.7 = 43.5 cm squared

Add all these together:

60 + 180 + 43.5 = 283.5 cm squared

The answer is thus 283.5 cm squared.

Answer:

283.5 cm²

Step-by-step explanation:

3 rectangles + 3 triangles on top + triangular base

3(10×6) + 3(½×10×4) + (½×10×8.7)

180 + 60 × 43.5

283.5 cm²

Answer:

yes, 1.5

Step-by-step explanation:

The ratios are equal. Then the triangle ΔRPQ is similar to the triangle ΔVAQ. And the ratio is 2: 1. Then the correct option is B.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The ratio of the corresponding sides are given as,

RP / AV = PQ / AQ

6 / 3 = 8 / 4

2 = 2

The ratios are equal. Then the triangle ΔRPQ is similar to the triangle ΔVAQ.

Thus, the correct option is B.
