Find the measure of the indicated angle to the nearest degree

Answer:

1. (3^3 + 3^2)^2 actually equals (27 + 9)^2

which is the first mistake

2. (27 + 9)^2 does not equal (3^5)2, so (36)^2 does not equal 3^7

3. 3^7 DOES NOT EQUAL 21

Step-by-step explanation:

when you add powered numbers together, it does not multiply it, as your example:

1. (3^3 + 3^2)^2 actually equals (27 + 9)^2

which is the first mistake

2. (27 + 9)^2 does not equal (3^5)2, so (36)^2 does not equal 3^7

3. 3^7 DOES NOT EQUAL 21

Hi there!

Error 1

[tex](3^3+3^2)^2\\= (3^5)^2[/tex]

The student added the exponents of 3³ and 3² and wrote 3⁵. This rule can only be applied to exponents with the same base that are being multiplied. 3³ and 3² were being added, not multiplied, so this rule can't be applied.

Error 2

[tex](3^5)^2\\= 3^7[/tex]

When a power has a power, we multiply them, not add. Here is the correct way of doing it:

[tex](3^5)^2\\= 3^5^*^2\\= 3^1^0[/tex]

Error 3

[tex]3^7\\= 21[/tex]

The student multiplied 3 and 7 to get 21, but 3⁷ actually means 3 multiplied by itself 7 times. The correct answer for this part would be 2187.

Answer:

-1

Step-by-step explanation:

are you sure this is the right equation ? it would mean that the more toppings the cheaper the ice cream.

but as it is written, the slope is -1.

the slope of a line is always the factor of the variable in the equation.

it is the ratio of y/x indicating how many units y is changing for a given change of x.

in our example here, if x changes 1 unit to the right (+1), then y changes 1 unit down (-1).

so, -1/+1 = -1

The slope of the function f(t) = 3 - t is -1

"It defines a relation between input and output values."

"It is the rate of change of the dependent variable of the function with respect to that of the independent variable."

For given question,

We have been given a function f(t) = 3 - t

We need to find the slope of the function.

[tex]m=\frac{d}{dt}f(t)\\\\ m=\frac{d}{dt}( 3 - t)\\\\m=-1[/tex]

Therefore, the slope of the function f(t) = 3 - t is -1

Answer:

below

Step-by-step explanation:

that is the procedure above

The factorized form of x² + 6x + 5 - 4y - y² is:(x + 1)(x + 5) - (4y + y²)

To factorize the expression x² + 6x + 5 - 4y - y², group the terms and factor them separately.

Rearranging the terms

(x² + 6x + 5) - (4y + y²)

Now let's factor each group separately:

1. Factoring x² + 6x + 5:

The quadratic expression x² + 6x + 5 can be factored into two binomial factors. We look for two numbers that multiply to give 5 and add up to 6 .

These numbers are 1 and 5:

(x + 1)(x + 5)

2. Factoring -4y - y²:

The terms -4y - y² have a common factor of -1.

Factoring out -1 gives

-1(4y + y²)

Combining the factorization of both groups

(x + 1)(x + 5) - 1(4y + y²)

Therefore, the factorized form is (x + 1)(x + 5) - (4y + y²).

730.88

Step-by-step explanation:

Area of the entire circle = pi * r^2

r = 16

Area = 3.14 * 16^2

Area = 803.84

1/4 of the circle contains the shaded area. It's area = 1/4 * 803.84

Area of 1/4 circle =

200.96

the area of the triangle

Area = 1/2 AG * G?

AG and G? are equal

Area = 1/2 * 16^2

Area = 128

Area of 1/4 circle - area of the triangle = area of the shaded portion

shaded portion = 200.95 - 128

Shaded Portion = 72.96

So the area of the unshaded part

unshaded = 803.84 - 72.96

Answer:

He received 10 dimes and 15 quarters.

Step-by-step explanation:

Dimes = $0.10

Quarters = $0.25

Variable x = dimes

Variable y = quarters

Create a pair of linear equations:

0.10x + 0.25y = 4.75

x + y = 25

Isolate any variable, using an equation of your choice:

x + y = 25

x = 25 - y

Plug in this new value of x into the other equation:

0.10(25 - y) + 0.25y = 4.75

Use the distributive property:

2.5 - 0.10y + 0.25y = 4.75

Combine like terms:

2.5 + 0.15y = 4.75

Isolate variable y:

0.15y = 2.25

y = 15

Plug in the value of y into any equation:

x + y = 25

x + 15 = 25

Isolate variable x:

Step-by-step explanation:

a) Metodo de reduccion:

Para aplicar este metodo debemos multiplcar por 3 la ecuacion 2 y sumarlas.

[tex]4x-3y=6[/tex]

[tex]5x+y=17[/tex] *3

[tex]4x-3y=6[/tex]

[tex]15x+3y=51[/tex]

-------sumamos las ecuacioens--------

[tex]19x=57[/tex]

[tex]x=3[/tex]

Ahora, remplazamos x en la ecuacion 2.

[tex]5(3)+y=17[/tex]

[tex]y=2[/tex]

b) Igualacion

Debemos despejar x en ambas y luego igualarlas

[tex]x=\frac{6+3y}{4}[/tex]

[tex]x=\frac{17-y}{5}[/tex]

Igualando:

[tex]\frac{6+3y}{4}=\frac{17-y}{5}[/tex]

[tex]5(6+3y)=4(17-y)[/tex]

[tex]19y=8[/tex]

[tex]y=2[/tex]

Ahora, remplazamos y en la ecuacion 2.

[tex]5x+2=17[/tex]

[tex]5x=15[/tex]

[tex]x=3[/tex]

c) Sustitucion

Despejamos x de la primero ecuacion y lo remplazamos en dos.

[tex]x=\frac{6+3y}{4}[/tex]

[tex]5\frac{(6+3y)}{4}+y=17[/tex]

Multiplicamos por 4

[tex]5(6+3y)+4y=68[/tex]

[tex]30+15y+4y=68[/tex]

[tex]30+19y=68[/tex]

Given:

Total Yogurt = [tex]8\dfrac{1}{4}[/tex] cups

Yogurt required for each smoothie = [tex]\dfrac{11}{16}[/tex] cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

[tex]\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}[/tex]

Substituting the given values, we get

[tex]\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}[/tex]

[tex]\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}[/tex]

[tex]\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}[/tex]

[tex]\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}[/tex]

[tex]\text{Number of smoothies}=3\times 4[/tex]

[tex]\text{Number of smoothies}=12[/tex]

Therefore, the number of smoothies is 12.

Given:

The tens digit of a two digit number is 5 greater the units digit.

If you subtract double the reversed number from it, the result is a fourth of the original number.

To find:

The original number.

Solution:

Let n be the two digit number and x be the unit digit. Then tens digit is (x+5) and the original number is:

[tex]n=(x+5)\times 10+x\times 1[/tex]

[tex]n=10x+50+x[/tex]

[tex]n=11x+50[/tex]

Reversed number is:

[tex]x\times 10+(x+5)\times 1=10x+x+5[/tex]

[tex]x\times 10+(x+5)\times 1=11x+5[/tex]

If you subtract double the reversed number from it, the result is a fourth of the original number.

[tex]11x+50-2(11x+5)=\dfrac{1}{4}(11x+50)[/tex]

[tex]11x+50-22x-10=\dfrac{1}{4}(11x+50)[/tex]

[tex]40-11x=\dfrac{1}{4}(11x+50)[/tex]

Multiply both sides by 4.

[tex]160-44x=11x+50[/tex]

[tex]160-50=11x+44x[/tex]

[tex]110=55x[/tex]

Divide both sides by 55.

[tex]\dfrac{110}{55}=x[/tex]

[tex]2=x[/tex]

The unit digit is 2. So, the tens digit is [tex]2+5=7[/tex].

Therefore, the original number is 72.

Answer:

5 hours

Step-by-step explanation:

Company A:

Charge for an hour =$ 25

Charge for 't' hours = 25 *t = 25t

Total cost = Equipment fee + charge for t hours

  AA = 150 + 25t

Company B:

Charge for an hour =$ 35

Charge for 't' hours = 35 *t = 35t

Total cost = Equipment fee + charge for t hours

  BB = 100 + 35t

BB = AA

100 + 35t = 150 + 25t

Subtract 25t from both sides

100 + 35t - 25t = 150

           100 +  10t = 150

Subtract 100 from both sides

10t = 150 - 100

10t = 50

Divide both sides by 10

t = 50/10

t = 5

Answer:

[tex]58, 68, 68, 68, 74, 74, 76, 77, 78, 79[/tex]

Step-by-step explanation:

Given

[tex]n=10[/tex]

[tex]Mean = 72[/tex]

[tex]Median = 74[/tex]

[tex]Mode = 68[/tex]

[tex]Range = 21[/tex]

Required

The complete dataset

The question has missing options (available online)

From the mean, we have:

[tex]Mean = \frac{\sum x}{n}[/tex]

This gives:

[tex]72 = \frac{\sum x}{10}[/tex]

Cross  multiply

[tex]\sum x = 72 * 10[/tex]

[tex]\sum x = 720[/tex]

This means that the sum of all elements of the dataset is 720

Next, we test the median

Since n = 10, then:

[tex]Median = \frac{n + 1}{2}[/tex]

[tex]Median = \frac{10 + 1}{2}[/tex]

[tex]Median = \frac{11}{2}[/tex]

[tex]Median = 5.5th[/tex]

This implies that the median is the average of the 5th and 6th item.

So, we have:

[tex]Median = \frac{5th + 6th}{2}[/tex]

Cross multiply

[tex]5th + 6th = 2 * Median[/tex]

[tex]5th + 6th = 2 * 74[/tex]

[tex]5th + 6th = 148[/tex]

This means that the 5th and 6th element add up to 148

Also, we have:

[tex]Mode = 68[/tex]

This means that 68 has to appear at least twice in the dataset

[tex]Range = 21[/tex]

This implies that the difference between the highest and the least is 21.

The dataset that satisfies the above condition is:

[tex]58, 68, 68, 68, 74, 74, 76, 77, 78, 79[/tex]
