Answers

Answer:  -10; -2; 0

Step-by-step explanation:

≥ means greater or equal than.

-10 is equal -10, true.

-14 is less than -10, so false.

Based on these results, express the probability that a seventh grader chosen at

random will play the guitar as a fraction in simplest form?

Answers

Answer:

[tex]Probability = \frac{11}{40}[/tex]

Step-by-step explanation:

Given

See attachment

Required

The probability that a 7th grader selected will play guitar.

From the attachment, we have:

[tex]7th\ graders =11+8+8+13[/tex]

[tex]7th\ graders =40[/tex]

7th graders that can play guitars are:

[tex]Guitars = 11[/tex]

So, the probability is:

[tex]Probability = \frac{Guitars}{7th\ graders}[/tex]

[tex]Probability = \frac{11}{40}[/tex]

A trapezoid with an area of 36 inches squared.

What is the area of the enlarged trapezoid?
54 in.²
81 in.²
576 in.²
864 in.²

Answers

Answer:

B. 81 in.²

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.

The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

1.5 × 1.5 = 2.25

Area of new trapezoid: 2.25 × 36 in²

Area of new trapezoid = 81 in²

The area of the enlarged trapezoid would be 81 in² or option B.

The answer is b. 81 in.²

Answers

Answer:

[tex]V=502.5\ cm^3[/tex]

Step-by-step explanation:

The area of the pentagonal base, A = 33.5 cm²

The height of the prsim,h = 15 cm

We need to find the volume of the pentagonal base prism. The formula for the volume of the pentagonal base prism is given by :

[tex]V=A\times h\\\\V=33.5\times 15\\\\V=502.5\ cm^3[/tex]

So, the required volume is [tex]502.5\ cm^3[/tex].

If HI = 7, find KL.

Answers

Answer:

14

Step-by-step explanation:

(I go to a french school, so excuse my terminology, which might not always be correct)

The angle we can see, in GHI, is equal to 121°. JKL has an identical angle, meaning JKL is an enlargement (probably the wrong term, I apologise) of GHI. This means we can use the length of it's sides to find KL.

GH and GI are both multiplied by two (GH = 4 becomes JK = 8, GI = 5 becomes JL = 10) meaning you must multiply HI by 2 to find KL.

2*7 = 14

KL = 14

Two heads 35 Two tails 23 One head, One tail 52 What is the theoretical probability that a coin toss results in two heads showing?

Answers

Answer:

[tex]Pr = 0.25[/tex]

Step-by-step explanation:

Given

Two heads ---> 35

Two tails ---> 23

One head, One tail ---> 52

Required

The theoretical probability of 2 heads

When a coin is tossed, the probabilities are:

[tex]P(Head) = 0.5[/tex]

[tex]P(Tail) = 0.5[/tex]

So, the theoretical probability of 2 heads is:

[tex]Pr = P(Head) * P(Head)[/tex]

[tex]Pr = 0.5 *0.5[/tex]

[tex]Pr = 0.25[/tex]

Step-by-step explanation:

It states that the figures in the pair are similar

When you multiply 5*8 it gives you 40 on the first angle

If the figures are similar then the other angle will equal 40.

So we need to find out which number that is multiplied by 12 that will give you 40.

If we multiply [tex]12*3\frac{1}{3}[/tex], it should  give you 40.

Convert The mixed number into a improper fraction:

3 1/3=3*3+1/3

=10/3

Convert the element into a fraction:

12/1*10/3

Factor the number:

3*4/1=10/3

Cross - cancel the common factor: 3

4/1*10/1

Apply the fraction rule:

4*10/1*1

Multiply the numbers: 4*10=40

=40/1*1

Multiply the numbers: 1*1=1

=40/1

Apply the Fraction rule:

Together they ran a total of 30 laps. Runner B ran 6 more than twice as many laps as Runner A. Part A: Write an equation for this situation. Use a variable to represent the number of laps for Runner A. Part B: How many laps did Runner A run? Part C: How many laps did Runner B run?

Answers

Answer:

Step-by-step explanation:

Number of laps run by Runner A = x

Number of laps run by Runner B = y

Runner B ran 6 more than twice as many laps as Runner A.

b = 6 + 2a

Together they ran a total of 30 laps.

a + b = 30

Part A: Write an equation for this situation. Use a variable to represent the number of laps for Runner A.

Part B: How many laps did Runner A run?

a + b = 30

b = 6 + 2a

Hence:

a + 6 + 2a = 30

3a = 30 - 6

3a = 27

a = 27/3

a = 9 laps

Part C: How many laps did Runner B run?

a + b = 30

b = 30 -9

b = 21 laps

The price of an object with 13% value added tax is 5763 . what will be the value added tax amount ? find it​

Answers

Answer:

100. ~113

x ~ 5763(assume that X is price without VAT)

100×5763=113×x

X. =(5763×100)/113. (5763/113=51)

X= 51×100

X =5100

VAT=5763-5100

=RS.663

The value added tax amount will be "663".

Given:

Interest rate,

13%

Object price,

5763

The value added tax will be:

→ [tex]\frac{13 \ percent}{100+13} = \frac{VAT}{5763}[/tex]

→       [tex]VAT = 5763\times \frac{0.13}{1.13}[/tex]

What is the surface area of the rectangular prism?

36 cm²

108 cm²

72 cm ²


54 cm²

Answers

Answer:

SA = 108cm² (the 2nd option)

Step-by-step explanation:

h = 4

l = 3

w = 6

SA = 2(lw + lh + wh)

SA = 2((3)(6) + (3)(4) + (6)(4))

SA = 2(18 + 12 + 24)

SA = 2(54)

SA = 108cm²

The surface area of the rectangular prism is 108cm².

Calculation of the surface area of the rectangular prism:

Since

height = 4

length = 3

width = 6

So, here the surface area is

SA = 2(lw + lh + wh)

= 2((3)(6) + (3)(4) + (6)(4))

= 2(18 + 12 + 24)

= 2(54)

= 108cm²

hence, The surface area of the rectangular prism is 108cm².
