Answer:

[tex]a=63[/tex]

Step-by-step explanation:

[tex]14=\frac{2a}{9}[/tex]

Switch sides:

[tex]\frac{2a}{9}=14[/tex]

Multiply both sides by 9:

[tex]\frac{9\cdot \:2a}{9}=14\cdot \:9[/tex]

[tex]2a=126[/tex]

Divide both sides by 2:

[tex]\frac{2a}{2}=\frac{126}{2}[/tex]

[tex]a=63[/tex]

Answer:

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

a² = b² + c²

where

a is the hypotenuse

b and c are the other two sides

So we have

[tex] {x}^{2} = {12}^{2} + {9}^{2} \\ {x} = \sqrt{ {12}^{2} + {9}^{2} } \\ x = \sqrt{144 + 81} \\ x = \sqrt{225} [/tex]

We have the final answer as

Answer:

21 rides

Step-by-step explanation:

let x = number of rides you can ride

32.50 + 0.80x [tex]\leq[/tex] 50

subtract 32.50 from both sides

0.8x [tex]\leq[/tex] 17.5

divide the left and right by 0.8

x [tex]\leq[/tex] 21.875

this means you can ride 21 times, because you can't ride a ride unless you can afford the whole cost

how to check; 32.50 + 0.8(21) is 49.30 and 80 cents more would go over your 50 dollar spending limit

Answer: 5.73

Step-by-step explanation:

Answer:

draw line and name it as R, S and T

then,

RS= 5x

ST=3x.... label it

now,

5x+3x=48

8x=48

x=6

RS=5x6=30

Step-by-step explanation:

RS Means is a division of Reed Business Information that provides cost information to the construction industry so contractors in the industry can provide accurate estimates and projections for their project costs.

The length of RS is 6 units.

It is required to find the length of RS.

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

RS= 5x

ST=3x

RT = 48

now,

RS+ST=RT

Substitute the value we get,

5x+3x=48

8x=48

x=6

RS=5x6

RS=30

Therefore, the length of RS is 6 units.

Answer:

y=x^4 is a function

Explanation:

A function is defined as given an equation, there should be only one corresponding, y value for any x value. In the table from the picture you attached, it is shown as for each x value, there is one corresponding y value. Therefore, x^4 is a function.

The given expression y = x⁴ is a function.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Answer:

6 stuffed animals

Step-by-step explanation:

If Caitlin gave away 6 stuffed animals, she is left with 12.

If Allie gave away three times as many as Caitlin, which would be 18, would leave her with 12.

The number of stuffed animals Caitlin gives away will be 6. Then the correct option is B.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Caitlin started with 18 stuffed animals and gave away x stuffed animals. Allie started with 30 stuffed animals and gave away three times as many stuffed animals as Caitlin did. Then the equations will be

y = 18 - x         ...1

y = 30 - 3x     ...2

From equations 1 and 2, then the value of x will be

18 - x = 30 - 3x

3x - x = 30 - 18

2x = 12

x = 6

The number of stuffed animals Caitlin gives away will be 6. Then the correct option is B.

Answer:   52°

Step-by-step explanation:

[tex]\sin \theta=\dfrac{\text{side OPPOSITE of angle}}{\text{HYPOTENUSE}}\\\\\\\sin \theta =\dfrac{23}{29}\\\\\\.\quad \theta=\sin ^{-1}\bigg(\dfrac{23}{29}\bigg)\\\\\\.\quad \theta =52.47^o[/tex]

Rounded to the nearest degree: Ф = 52°

Step-by-step explanation:

Hey there!

Here;

The figure given is a Right angled triangle.

Let the unknown angle be a refrence angle.

Now,

p = 23

h = 29

In ratio of sin there is 'p' and 'h'. So, using sin ratio.

[tex] \sin( \alpha ) = \frac{p}{h} [/tex]

[tex] \sin( \alpha ) = \frac{23}{29} [/tex]

[tex] \alpha = { \sin}^{ - 1} (0.7931034)[/tex]

[tex] \alpha = 52.47°[/tex]

Therefore the the angle is 52°.

Correct Question:

Type the correct answer in the box. Use numerals instead of words. Consider this expression. [tex]\sqrt{a^2} - 7 + |b|[/tex] When a = 2 and b = -4, the value of the expression is​

Answer:

[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]

Step-by-step explanation:

Given

[tex]a=2[/tex]

[tex]b = -4[/tex]

Required

Determine [tex]\sqrt{a^2} - 7 + |b|[/tex]

To solve this, we simply substitute the values of a in the given expression

[tex]\sqrt{a^2} - 7 + |b|[/tex]

[tex]\sqrt{a^2} - 7 + |b| = \sqrt{2^2} - 7 + |-4|[/tex]

Express 2² as 4

[tex]\sqrt{a^2} - 7 + |b| = \sqrt{4} - 7 + |-4|[/tex]

Express square root of 4 as 2

[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + |-4|[/tex]

[tex]|-4| = 4[/tex]

So, we have

[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + 4[/tex]

[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]

Hence, the result of the expression is -1
