The perimeter of the rectangular top of a bookcase is 54 in. Find the length of the width is 7 in.​

Answers

Answer 1

Step-by-step explanation:

P = L × B

54 = L × 7

54 = 7L

Therefore, L = 54 ÷ 7

L = 7.71

Jo is playing a game in which he must roll a die and toss a coin. What is the probability that Jo will roll a 6 and toss a heads? Make a list to support your answer.

Answers

Answer:

1/ 12

Step-by-step explanation:

Sample space :

(H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6)

Probability = required outcome / Total possible outcomes

Required outcome = roll a 6 and toss a heads = 1

Total possible outcomes = sample space = 12

= 1/12

What is the slope for (-2,1) and (7,1)

Answers

Answer:

m=0

Step-by-step explanation:

the slope (m) can be calculated from two points with the formula (y2-y1)/(x2-x1)

we are given the points (-2,1) and (7,1)

label the points:

x1=-2

y1=1

x2=7

y2=1

now substitute into the equation

m=(1-1)/(7--2)

m=0/9

m=0

the slope of the line is 0

Answers

Answer:

  152°

Step-by-step explanation:

If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.

The measure of each angle in the other congruent pair is 152°.

PLZ HELP!!!! solve for x​

Answers

Answer:

64 degrees

Step-by-step explanation:

Combining the 90 degrees, x degrees, and 26 degrees creates a flat angle or 180 degrees

so first, combine 90 and 26 degrees

90+26= 116

then subtract 116 from 180

180-116= 64 degrees

slope intercept form of points (0,4) and (1,3

Answers

Answer:

y = -x+4

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 4-3)/(0-1)

   = 1 /-1

  = -1

The y intercept is (0,4) or 4

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -x+4

Calculate the unknown sides and angles of the triangle ABC given.
Given the final answer correct to three significant figures.
C= 25.7° , b= 3.5cm, a = 6cm​

Answers

Answer:See below

Step-by-step explanation:

to understand thisyou need to know about:law of sinelaw of cosinePEMDASlet's solve:

there are 3 ways to solve SAS triangle

use The Law of Cosines to calculate the unknown side,then use The Law of Sines to find the smaller of the other two anglesand then use the three angles add to 180° to find the last angle.

first figure out [tex]\angle C [/tex]

to do so we will use the formula of law of cosine of C angle

[tex] {c}^{2} = {a}^{2} + {b}^{2} - 2ab.\cos(C) [/tex]

substitute the given values of a,b and [tex]\angle C[/tex]

[tex] \sf{c}^{2} = {6 }^{2} + {3.5}^{2} - 2.6.(3.5). \cos( {25.7}^{ \circ} ) [/tex]

simplify squares:

[tex]c^{2}=36+12.25-42.\cos(25.7^{\circ})[/tex]

simplify addition:

[tex]c^{2}=48.25-42.\cos(25.7^{\circ})[/tex]

square root both sides

[tex] \sf \: \sqrt{ {c}^{2} } = \sqrt{ 48.25-42. \cos(25.7^{\circ})}[/tex]

simplify:

therefore

[tex]\bold{c=3.23}[/tex]

use law of sine to figure out angle A

[tex] \dfrac{6}{\sin( \angle \: A) } = \dfrac{3.23}{\sin(25.7)} [/tex]

therefore

[tex]\bold{\angle A=53.66°}[/tex](use calculater to simplify it)

therefore

[tex]\angle B\: is\: 180^{o}-25.70^{o}-53.66^{o}[/tex]

[tex]\bold{= 100.64}[/tex]

Question 10 of 20. POOS The dimensions of a right rectangular prism are shown below. 1 in. How many cubes with side lengths of inch are needed to fill the prism without gaps or overlaps? 36 cubes 91 cubes 216 cubes 546 cubes

Answers

Answer:

546

Step-by-step explanation:

From the attached picture ;

Volume of a rectangular prism = (width * length * height)

Volume = 2 1/6 * 1 1/6 *1

Volume =. 13/6 * 7/6 * 1

Volume = 91 / 36 in³

Side length, a of cube = 1/6

Volume of cube = a³ = (1/6)^3 = 1/216

(91/36) ÷ 1/216

Total amount = P (1 + i)t Alisha has a five–year car loan of $15,000 with an interest rate of 6 percent. If the interest is compounded annually, how much will she pay in total for her car?

Answers

Answer:

$20070

Step-by-step explanation:

Given data

Time= 5 years

Principal= $15,000

Rate= 6%

Total amount=  P (1 + i)^t

substitute

Total amount=  15000(1 + 0.06)^5

Total amount=  15000 (1.06)^5

Total amount=  15000*1.338

Total amount=  $20070

En el transcurso del 2015 – 2018 visitaron alrededor de 8700 turistas la playa, de los cuales el 35,10% fueron Extranjeros y el 64,9% fueron nacionales. ¿Cuántos turistas fueron extranjeros y cuantos nacionales?

Answers

Answer:

Los turistas extranjeros fueron 3054 y los turistas nacionales fueron 5646.

Step-by-step explanation:

De acuerdo a la información proporcionada, debes calcular el 35,10% del total de turistas para determinar el número de turistas extranjeros y el 64,9% del total de turistas para encontrar el número de turistas nacionales:

8700*35,10%=3054

8700*64,9%=5646

De acuerdo a esto, la respuesta es que los turistas extranjeros fueron 3054 y los turistas nacionales fueron 5646.

Answers

Answer:

16 9/20 years old

Step-by-step explanation:

Leo is 13 3/ 4 years old.

Step 1

Sheila is 1 1 /2 years older than Leo

Sheila = 13 3/4 years + 1 1/2 years

13 + 1 + ( 3/4 + 1/2)

Lowest common denominator 4

14 + ( 3 + 2/4)

14 + 5/4

= 14 + 1 1/4

= 15 1/4 years old

Jane is 1 1/ 5 years older than Sheila.

Jane's age = 15 1/4 years old + 1 1/5 years

15 + 1 + (1/4 + 1/5)

Lowest common denominator = 20

16 + (5 + 4/20)

16 9/20 years old

Therefore, Jane is 16 9/20 years old
