Can someone please help with this math problem

Answer:

n=58

Step-by-step explanation:

the square at the bottom right indicates that, that angle equals 90.

all the angles in a triangle add up to equal 180 so we subtract the angles that are given from 180 to get the missing angle

180-90-32=58

n=58

Answer:

assuming angle RST=90 degrees

h=19

Step-by-step explanation:

RU/h=h/UT

RU=RT-UT=42-12=30

30/h=h/12

h^2=360

h=18.97   rounded to nearest tenths=19

Answer: No, it is unlikely that a student chosen at random will have only 2 siblings.

Step-by-step explanation:

Given: Number of students with 2 siblings = 10

Total students = 6+7+10+3 =26

The probability of choosing a student with only 2 siblings = [tex]\dfrac{\text{Number of students with 2 siblings}}{\text{Total siblings}}[/tex]

[tex]=\dfrac{10}{26}\\\\=\dfrac{5}{13}\approx0.38<0.5[/tex]

Hence, it is not likely that a student chosen at random will have only 2 siblings.

Answer:

3w < 18

Step-by-step explanation:

To do 3 times if you put 3 against a variable that means to multiply. Since a number is unknown it turns into variable which is w in this case. Then less than 18 to do the less than symbol, think of them like crocodile they always eat the bigger number and since 3w is less than 18 the croc < eats 18. Thats just an easy way of remembering. Hope this helps :)

Answer: Yes

Answer:

[tex]P_1 = 24cm[/tex]

Step-by-step explanation:

Represent:

Phil's height with P

Suzanne's height with S

Phil's shadow with P1

Suzanne's shadow with S1

So, we have:

[tex]P = 51.2cm[/tex]

[tex]S = 5'4"[/tex]

[tex]S_1 = 76.2cm[/tex]

Required

Calculate the length of Phil's shadow --- Missing part of question

To do this, we make use of the following equivalent ratio.

[tex]P:S = P_1 : S_1[/tex]

Convert [tex]S = 5'4"[/tex] to cm

[tex]S = 5ft\ 4in[/tex]

[tex]S = (5*30.48+ 4*2.54)cm[/tex]

[tex]S = 162.56cm[/tex]

Substitute values for P, S and S1

[tex]51.2cm : 162.56cm = P_1 : 76.2cm[/tex]

Express as fraction

[tex]\frac{51.2cm}{162.56cm} = \frac{P_1 }{ 76.2cm}[/tex]

Make P1 the subject

[tex]P_1 = 76.2cm * \frac{51.2cm}{162.56cm}[/tex]

[tex]P_1 = 76.2cm * \frac{51.2}{162.56}[/tex]

[tex]P_1 = \frac{76.2cm * 51.2}{162.56}[/tex]

[tex]P_1 = \frac{3901.44cm}{162.56}[/tex]

[tex]P_1 = 24cm[/tex]

Hence, the length of Phil's shadow is 24 cm

Answer:

width = 5 ft

length = 9 ft

Step-by-step explanation:

Here, we want to get the length and width of the garden

length is 1 ft less than twice the width

if width = w

length = 2w-1

The product of the two is 45

so, we have it that;

w(2w-1) = 45

2w^2 - w = 45

2w^2 - w -45 = 0

2w^2 - 10w + 9w -45 = 0

2w(w-5) + 9(w-5) = 0

(2w + 9)(w-5) = 0

2w + 9 = 0

or w -5 = 0

w = 5 or-9/2

w cannot be negative, so we = 5

l = 2(5) -1 = 10 - 1 = 9 ft

Answer:

4x

Step-by-step explanation:

Answer:

A. 2x is correct.

Step-by-step explanation:

Finding the measure of the segment BC and ST by the Distance formula: B (5, 7), C (8, 8), S (1, 11), T (7, 13).

BC = √(8-5)² + (8 - 7)²

BC = √10

ST = √( 7 - 1)² + ( 13 - 11)²

ST = 2√10

Scale Factor = Image/ Pre-image = ST/BC = 2√10/√10 = 2

This means that the image, ST, is twice as large as the pre-image BC.

Answer:

a) x = 492/738

b) m<p = 39°

   m<n = 141°

Step-by-step explanation:

Find the diagram attached

a) The sum of angle on the straight line l is 180degrees

m<n + m<p = 180 degrees

Given

<p = 21x+25

<n = (675x-27)/3

Substitute the given values into the formula

(675x-27)/3 + 21x+25= 180

[(675x-27+3(21x+25))]/3 = 180

675x-27+63x +75 = 180*3

675x+63x-27+75 = 540

738x+48 = 540

738x = 540 - 48

738x = 492

x = 492/738

b) m<p = 21x+25

m<p = 21(492/738) + 25

m<p = 14+25

m<p = 39°

Recall that m<p + m<n = 180

m<n = 180-m<p

m<n = 180 -39

m<n = 141°

Answer:

I think 2 is the coefficient of x which is numerical.

3x+5x+1=17

x=2

y=5•2+1

y=1

(x, y)=(2, 11)

3x+2(4x+5)=43

x=3

y=4•3+5

y=17

(x, y)=(3, 17)

I think I did it right and I hope I helped you

Answer:

B, -3

Step-by-step explanation:

-4x+5=17

this equation can be used to determine the number

-4x=12

x=-3

l = 5 + 2w.

P = 88 cm.

P = 2 ( l + w )

88 cm = 2 ( (5 + 2w) + w)

88 cm = 2 (5 + 3w)

88 cm cm = 10 + 6w

88 cm cm - 10 = 6w

78 cm = 6w

78 cm : 6 = w

13 cm = w

The width is 13 cm.

Answer:

7 people went to the basketball game.

Step-by-step explanation:

Giving the following information:

They parked the car in a parking lot which charged $5. The cost per ticket was $24.

To calculate the number of people, we need to use the following formula:

Total cost (y)= x*24 + 5

173 = 24x + 5

168/24 = x

7 = x

7 people went to the basketball game.
