Answer: 25+3x =133

Step-by-step explanation:

Let x = the amount Rodney saved last month

Cost of camera Rodney wants to buy= $133 , which is $25 more than 3 times the amount he saved last month.

i.e. 25+3(amount Rodney saved last month) = Cost of camera  (in dollars)

i.e. 25+3x =133   (in dollars)

Hence, the equation could be used to solve for x : 25+3x =133

The round off -5 1/2 to whole number is -6.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Fraction: -5 1/2

Now, converting it to the decimal

= -11/2

= -5.5

now, rounding off to whole -5.5 will lie between -5 and -6.

Hence, the whole number round off for - 1/2 is -6.

Area of a triangle

Side Angle Side (SAS) Method :

Given a triangle with two known sides a and b, and their included angle C, the area can be calculated as follows:

[tex]\displaystyle A=\frac{a.b.\sin(C)}{2}[/tex]

The triangle has sides of lengths a=7 and b=9 and their included angle is C=72°. Substituting:

[tex]\displaystyle A=\frac{7\cdot 9.\sin(72^\circ)}{2}[/tex]

Answer:

its bc 3x226 is 678 2x339 is 678 and 6 x 113 is 678

Step-by-step explanation:MARK BRAINLIEST I NEED 1 MORE

Using the divisibility rules, 678 is divisible by 2, 3, and 6.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We need ot find that 678 is divisible by 2, 3, and 6.

WE can see 678 is even, so it's divisible by 2

Now, the sum of digits are 6+7+8 = 21, which is divisible by 3, so 678 is divisible by 3

Since 678 is divisible by both 2 and 3, then it has to be divisible by 6

Using the divisibility rules, we can conclude that 678 is divisible by 2, 3, and 6.

The percent of the sixth-grade class that said they would like to be a movie director is A. 23%.

It's important to note that a percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

In this case, the sixth-grade class was asked the question, “What job would you like the best and the results are shown in the table.

.

The. total number will be:

= 84 + 92 + 124 + 100

= 400

The percent of the sixth-grade class that said they would like to be a movie director will be:

= Movie director / Total number × 100

C. 0.446

Step-by-step explanation:

1-(0.114+0.332) = 0.446

The sum of the relative frequencies of the bars for 4 and 5 is 0.446.

The probability that atleast four of the next five flights will be overbooked is the sum of the probabilities of having 4 or 5 flights overbooked which is 0.446

The probability of having atleast 4 flights overbooked can be defined as :

P(X ≥ 5) = P(X = 4) + P(X = 5)

From the probability distribution displayed on the histogram :

P(X ≥ 5) = 0.332 + 0.114 = 0.446

Therefore, the probability of having atleast 4 flights overbooked ls 0.446

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ [tex]27^{- 1/3} = \frac{9^{1/4} }{3^{x + 1} }[/tex]

Now,

Since, The expression is,

⇒ [tex]27^{- 1/3} = \frac{9^{1/4} }{3^{x + 1} }[/tex]

Solve for x as;

[tex]3^3^*^{- 1/3} = 3^2^*^{1/4} * 3^{x + 1} }\\\\3^{-1} = 3^{1/2} * 3^{x + 1} \\\\3^{-1} = 3^{1/2} ^+^{x + 1}[/tex]

By comparing we get;

⇒ - 1 = 1/2 + x + 1

Solve for x as;

⇒ - 1 - 1 = 1/2 + x + 1 - 1

⇒ - 2 - 1/2 = x

⇒ x = - 5/2

Thus, The value of x = - 5/2

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or and it follows Pythagoreans theorem.

Given that,

Sides of triangles are 156cm, 133cm and 205cm

To verify, this triangle is a right angle triangle,

Use Pythagorean formula,

Sum of square of two sides = third Side

(156)²+(133)²= 24336+17689

                    = 42025

(205)² = 42025

Answer:

time greater than 6 hours

Step-by-step explanation:

For this problem, we are given the rate at which the refrigerator's temperature increases and the rate at which the oven's temperature decreases along with the initial temperatures for both.  Using this information, we can determine the amount of time that will need to pass for the two to have equal temperature, or pass each other in opposite directions of temperature.  Let's write the inequality using the information:

40 + 5t > 340 - 45t

Let t be the amount of time passed in hours.  So, we simply need to solve the inequality for t.

40 + 5t > 340 - 45t

40 + 50t > 340

50t > 300

t > 6

Given this information, we know that after 6 hours have passed, the temperature of the fridge and oven will be equal.  So we can say that any time greater than 6 hours, the fridge will have a higher temperature than the oven.

You have to multiply 8 and 7

Answer:

The whole angle on a circle is equal to 360°.

This means that:

∠A + ∠B = 360°.

Here we know that ∠A = 7°

Then ∠B = 360° - 7° = 353°

Now, if the probability is evenly distributed for all the angles, then the probability that the spinner lands in A is equal to the quotient between the measure of the angle A, and the measure of the total circumference, this will be:

Pa = 7°/360° = 0.019

And the same for B:

Pb = 353°/360° = 0.981

Now, the expected value can be calculated as:

Ev = ∑xₙ*pₙ

Where xₙ is the event n, and pₙ is its probability.

Then:

x₁ = A = 100

p₁ = Pa = 0.019

x₂ = B = 2

p₂ = Pb = 0.981

The expected vale will be:

Ev = 100*0.019 + 2*0.981 = 3.862

Rounding to the nearest hundredth, the second digit after the decimal point, we have:

Ev = 3.86

The equation of the line that passes through the given point has the same slope as the given equation.

The equation of the line that  passes through (-3,1) and is parallel to y=4−3x is y = -3x - 8.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Slope intercept form of a line is y = mx + c, where m is the slope and c is the intercept along the Y axis.

We have the required line is parallel to the line y = 4 - 3x.

Slope of parallel lines are same.

Slope of the required line = -3

Equation will be of the form y = -3x + c

Required line passes through (-3, 1).

Substituting the values of the point in the equation,

1 = (-3 × -3) + c

1 = 9 + c

c = -8

Equation becomes y = -3x - 8

Hence the required equation of the line is y = -3x - 8.

Doing this problem correctly requires the application of "order of operations" rules.  "x^2 plus 2y" actually means "(x^2 plus 2y"), and so your

x^2 plus 2y divided by 2x
