circle the subtractions below which use one of these two facts ​

Answer:

128°

Explanation:

total sum of interior angle in triangle is 180°

Find the missing angle inside the triangle:

180° - 38° - 90°

52°

∵ a straight line always has 180°

Now find for missing exterior angle:

x° + 52° = 180°

x° = 180° - 52°

x° = 128°

Answer:

128 degrees

Step-by-step explanation:

180-52= 128

so your answer is 128 degrees.

Answer:

No

Step-by-step explanation:

Because

14.99 + 1.50 = 16.49

16.49 + 6% = 17.4794

17.4794 + 20% = 20.97528

Now if you round 20.97528

It becomes 20.98

Slope:-

[tex]\\ \rm\rightarrowtail m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\rightarrowtail m=\dfrac{14-8}{7-10}[/tex]

[tex]\\ \rm\rightarrowtail m=\dfrac{-6}{-3}[/tex]

[tex]\\ \rm\rightarrowtail m=2[/tex]

Answer:

The line passes through the given points are ( 10,8) & (7,14)

here

x₁ = 10

y₁ = 8

x₂ = 7

y₂ = 14

We have been asked to slope of that line which passes through the given points .

Using Formulae

❍[tex] \bf \: m \: = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Put the given value we obtain

[tex] \sf \dashrightarrow \: m \: = \dfrac{14 - 8}{7 - 10} \\ \\ \sf \dashrightarrow \: m \: = \dfrac{6}{ - 3} \\ \\ \sf \dashrightarrow \: m \: = \dfrac{ - 2}{1} \\ \\ \sf \dashrightarrow \: m \: = - 2[/tex]

So, the slope of that line is -2 .

Answer: C

Step-by-step explanation:

[tex]25a^{2}=(5a)^{2}[/tex] and [tex]36b^{6}=(6b^{3})^{2}[/tex]

The slope is 3/2.

We take any two points, I took (-14,3) and (-12,6) for solving for the formula when finding slope.

The formula is Rise/Run or Change in Y/ Change in X.

y2-y1/x2-x1

6-3/-12-(-14)

= 3/2

Slope is 3/2

This is how to solve it.

Answer:

≈$3478.4

Step-by-step explanation:

Using the compound interest formula:

[tex]A = P(1+\frac{r}{n})^{nt}[/tex]

A = Total

P = Principle
r = Interest Rate

n = No. of times applied in each time period

t = No. of periods

In this case,

P = 3400

r = 1.14% = 0.0114

n = 12 (months)

t = 2 (years)

Hence,

[tex]A = 3400(1+\frac{0.0115}{12})^{12*2}[/tex]

[tex]A = 3478.372836......[/tex]

A ≈ 3478.4 (nearest cent)

To make this simpler, we know that [tex]0.15=\frac{15}{100}[/tex], so

   12 times [tex]\frac{15}{100}[/tex] = [tex]12 * \frac{15}{100} =\frac{180}{100} = 1.8[/tex]

Hope that helped!

Answer:

9.2 cm and 15% increase

Step-by-step explanation:

1.15*8 = 9.2

percentage increase

new square = 9.2*9.2 =84.64

old area=8*9.2 = 73.6

percentange increase = (84.64-73.6)/73.6 = 15%

Increase the width

As sides of square are equal

Area increases same as length i.e 15%

Answer:

Product before increasing: 4200

x after increase: 60 * 105% = 63

y after increase: 70 * 110% = 77

Product after increasing: 4851

Percentage increase in the product: 4851 / 4200 * 100 = 115.5%

Answer:

  156 °F

Step-by-step explanation:

Newton's Law of Heating results in the exponential function you show in your problem statement. We can use the given starting and "in-progress" temperatures and times to solve for the value of the factor "k" in the exponential function.

  [tex]T(t)=T_\infty+(T_0-T_\infty)e^{-kt}\\\\T(2.5)=123=305+(72-305)e^{-k\cdot2.5}\qquad\text{substitute given temps and times}\\\\\dfrac{123-305}{72-305}=e^{-2.5k}=\dfrac{182}{233}\qquad\text{subtract 305, divide by $(72-305)$}\\\\k=\dfrac{-1}{2.5}\ln\dfrac{182}{233}\approx0.0988127\approx0.099\qquad\text{rounded to 3 places}[/tex]

Then the temperature after 4.5 hours is ...

  T(4.5) = 305 -233e^(-0.099·4.5) ≈ 156 . . . . °F

It will take about 6.3 hours for the turkey temperature to reach 180 °F.

Answer:

1/2 or 6/12

Step-by-step explanation:

To get the area of the crate's top, multiply the length and width together. Should not multiply the height by anything because it simply measures the height of the box and not the length or breadth of any of its bases (the top and bottom of the box). When you multiply the length by 3/4 and the breadth by 2/3, you should obtain 6/12, or 1/2 yard squared, as your answer for the area of the crate's top.

To solve this problem, we are asked to divide the fraction. Whenever two fractions are given and the operation required is division, it is best to take the inverse of one of the fraction and then multiply it by the other fraction.

[tex]\frac{21}{58} / \frac{3}{8}[/tex]

This can become

[tex]\frac{21}{56} * \frac{8}{3} = \frac{7}{7} = 1[/tex]

Stem and leaf plots are used to visualize data, graphically

The true statement is (b) There are 30 buildings in the county that are taller than 50 feet.

From the stem and leaf plot, we have that the number of leaves is 30

This means that, the total frequency of the dataset is 30

So, the number of buildings taller than 50 feet is 30

Hence, the true statement is (b) There are 30 buildings in the county that are taller than 50 feet.

Answer:

A = 15 units²

Step-by-step explanation:

The figure has 1 pair of parallel sides and is therefore a trapezium.

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between bases and b₁, b₂ are bases

here h = 3, b₁ = 3 , b₂ = 7 , then

A = [tex]\frac{1}{2}[/tex] × 3 × (3 + 7) = 1.5 × 10 = 15 units²

The area of the square is the square of one of its sides. The area of the plate is 15 units².

The area of the square is the square of one of its sides.

[tex]\text{Area of square} = a^2[/tex]

The area of a triangle is half the product of its base and height.

[tex]\rm\text{Area of Triangle} = \dfrac{1}{2} \times Base \times Height[/tex]

The shape of the plate can be divided into two parts a square of side 3 cm and a triangle with of base 4 cm and a height of 3 cm, therefore, the area of the plate is,

[tex]\text{The area of the shape} = \text{Area of the triangle} + \text{Area of the square}[/tex]

                                 [tex]= (\dfrac{1}{2} \times 4 \times 3) + (3 \times 3)\\\\= 6 + 9\\\\=15\rm\ units^2[/tex]
