A triangle where one angle measures 20° and another angle measures 45°.Help please

Answer:

3 divided by 4 will equal 0.75 which is equivalent to 0.75. or you can do 6/8 which will also equal 0.75. and 6/8 is equivalent to 3/4. so therefore it's confirmed that 3/4 is equivalent to 0.75

Answer:

she needs to work 16 hours

Step-by-step explanation:

103° + 37° + < C = 180° { being sum of angles of triangle }

< C = 180° - 140°

< C = 40°

Answer:

Step-by-step explanation:

Scale factor  = 1 : 7

a)Let the length of the house in the scale drawing = x

1:7 :: x : 21

Product of means = Product of extremes

 7*x = 1* 21

     x = [tex]\frac{1*21}{7}[/tex]

     x = 3

Length of the house in the scale drawing = 3 in

b) Height of the real house =y

1 : 7 :: 4 : y

Product of extremes = product of means

1 * y = 7*4

   y = 7*4

   y = 28

Height of real house = 28 feet

Answer:

[tex]134 \frac{6}{5}[/tex]

Step-by-step explanation:

The computation of the distance travelled is shown below:

Total distance would be

[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]

Now if the same route would taken again in order to back home

So, the total distance would be doubled

[tex]= \frac{338}{5} \times 2\\\\ = \frac{676}{5} \\\\= 134 \frac{6}{5}[/tex]

Step-by-step explanation:

Angles QPS and QRS are supplementary as opposite angles of a cyclic quadrilateral.

Supplementary angles sum to 180°.

Correct choice is A

Answer:

x = 45

Step-by-step explanation:

Interior angles of a triangle sum up to 180

180 - 90 = 90

90 / 2 = 45

Answer:

X = 45

Step-by-step explanation:

Since all interior angles of a triangle add up to 180 and both of the missing angles are the same value, X would equal 45,

90+45+45=180

Answer:

Tallest = Morgan

Shortest = Suzanna

Step-by-step explanation:

Assuming Latisha = 1

0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.

1.09 is more than 1, Morgan is taller than Latisha.

Morgan is tallest and Suzanna is shortest, Latisha in the middle.

Answer:

0.225989

Step-by-step explanation:

3x+9+x-11=180

4x-3=180

4x=180-3

4x/4x=177/4x

0.225989

Answer:

=78 degrees

Step-by-step explanation:

complementary angles add up to 90 degrees

A + B = 90

3x + 9 + x - 11 = 90

3x + x + 9 - 11 = 90

4x - 2 = 90

collect like valuables

4x = 90 + 2

4x = 92

x =23

angle A = 3x + 9

             = (3 x 23) + 9

             = 69 + 9

             = 78

Answer:

a = 3.6

Step-by-step explanation:

[tex] \frac{2}{3} (6a + 9) = 20.4 \\ \\ \bigg( \frac{2}{3} . \boxed{6a} \bigg) + \bigg(\boxed{ \frac{2}{3}} . {9} \bigg) = \boxed{ 20.4} \\ \\ (2.2a) + (2.3) = 20.4 \\ \\ 4a + 6 = 20.4 \\ \\ 4a = 20.4 - 6 \\ \\ 4a = 14.4 \\ \\ a = \frac{14.4}{4} \\ \\ a = \boxed{3.6}[/tex]

Answer:

35y - 20

Step-by-step explanation:

Given

[tex]\frac{2}{5}[/tex](25y - 50) + 25y ← distribute parenthesis

= 10y - 20 + 25y ← collect like terms

= 35y - 20

Step-by-step explanation:

Put x as the width and x+8 as the length. The equation would be x(x+8)=33 and it would factor out as (x-3)(x+11). The width is 3 and the length is 11. The perimeter would be 28.

Answer:

you'll have to multiply 8 by itself to get your area so you have to do 8*8

Answer:

Names of Degrees

Degree Name Example

1 Linear x+3

2 Quadratic x2−x+2

3 Cubic x3−x2+5

4 Quartic 6x4−x3+x−2

Answer:

Quartic Trinomial

Step-by-step explanation:

Monomial = one term

Binomial = two terms

Trinomial = three terms

Polynomial = four or more terms

As the other answer says, the order for degrees is:

Linear - to first degree

Quadratic - to second degree

Cubic - to third degree

Quartic - to fourth degree

Quintic - to fifth degree

Anything above fifth degree is just said "__th degree"

Example: x^7 + x^2 + 5 would be seventh degree trinomial

Step-by-step explanation:

830(2) 28/13

​   ^ do that ok??????? plug it in!!!!!!!!

then do u know what u will get? u will get this !!!!!! y = 1145.09631989

round 2 da whole numba and den boom shakalaka B ) i got my question wrong so that i could put the right answer here. bye yall

The number of bacteria doubling every 28 hours will be 1145 after 13 hours.

The formula for exponential growth is y = y₀.e^(kt).

The formula for exponential decay is y = y₀.e^(-kt).

In the case of doubling the growth of bacteria, we can use the formula,

[tex]y_f = y_0\times2^{\frac{t_r}{t}[/tex], where [tex]y_f[/tex] represents the final population, [tex]y_0[/tex] is the initial population, [tex]t_r[/tex] is the time we are required to determine, and [tex]t[/tex] represents the time rate growth.

Therefore from the given information, the number of bacteria after 13 hours will be,

[tex]y_f = 830\times2^{\frac{13}{28}[/tex].

[tex]y_f = 830\times1.38[/tex].

[tex]y_f = 1144.86[/tex] or 1145 bacterias.

Q. In a lab experiment, 830 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 28 hours. How many bacteria would there be after 13 hours, to the nearest whole number?​

Answer: 52.8 kilometers

Step-by-step explanation:

This week she plans to run 2²/₅ times as much as last week.

If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.

First convert the improper fraction to a proper one:

2²/₅ = 12/5

= 12/5 * 22

= 264/5

= 52.8 kilometers
