Answers

Answer 1

older

brother x+5=2*11

x=17

young

brother 2*(y+3)=11+3

y=4

Answer 2

17 years old is Jason's older brother.

and, 4 years old is Jason's younger brother now.

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Jason is 11 years old. His older brother is 5 years less than twice as old as he is.

let, Jason's older brother is x years old.

older brother x+5=2*11

x=17

again,

In 3 years Jason will be twice as old as his younger brother.

let,  Jason's younger brother now is y years old.

young brother 2*(y+3)=11+3

y=4

Hence, 17 years old is Jason's older brother.

and, 4 years old is Jason's younger brother now.

lines s and t intersect so that the measure of angle 1 is 85 degrees. if angle 2 is supplement to angle 1 what is the measure of angle 2 ​

Answers

Answer:

95 degrees

Step-by-step explanation:

The sum of two supplementary angles is 180 degrees

Given

angle 1 = 85 degrees

If angle 2 is the supplement of angle 1, then

<1 + <2 = 180

85 + <2 = 180

<2 = 180 - 85

<2 = 95degrees

Hence the measure of angle 2 is 95 degrees

A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $912 on props, and 24% of the total budget on equipment. What was the total budget for their student film?

Answers

Answer:

Total Budget: $1200

Step-by-step explanation:

76% = 912

1% = 12

100% = 12 x 100 = $1200

I brute forced till I got the number which multiplied by 76 came out to 912 from there I had what was 1% of the budget then I multiplied that by 100 for the answer.

The total budget for their student film is $1200.

What is the percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100.

A group of friends were working on a student film.

They spent all their budget on props and equipment.

They spent $912 on props, and 24% of the total budget on equipment.

Let us represent the total budget of the film as: x

The amount spent on equipment = $870

The amount spent on props = 24% of x

Total budget = Amount spent on equipment + Amount spent on props

x = 912 + 24% of x

x = 912 + 0.24x

x - 0.24x = 912

0.76x = 912

x= 912/0.76

x = $1200

Hence, the total budget for their student film is $1200.

F a student drives 30 miles north, the 40 miles east, then 60 more miles north and finally 80 more miles east, exactly how far is she from her starting point? (As the crow flies.)

Answers

Answer:

150 miles

Step-by-step explanation:

The movements are represented as:

[tex]N1 = 30miles[/tex]

[tex]E1 = 40miles[/tex]

[tex]N2 = 60miles[/tex]

[tex]E2 = 80miles[/tex]

Required

Determine the distance from the starting point

The student's movement is illustrated with the attached image.

First, calculate the total distance towards North.

[tex]N = N1 + N2[/tex]

[tex]N = 30 + 60[/tex]

[tex]N = 90[/tex]

Next, calculate the total distance towards East

[tex]E = E1 + E2[/tex]

[tex]E = 40 + 80[/tex]

[tex]E = 120[/tex]

The total distance from the starting point is calculated using Pythagoras theorem.

[tex]D^2 = N^2 + E^2[/tex]

[tex]D^2 = 90^2 + 120^2[/tex]

[tex]D^2 = 22500[/tex]

[tex]D = \sqrt{22500[/tex]

[tex]D = 150[/tex]

They employed less-experienced teachers than the Anglo schools. Chicano children were given shabbier books and equipment than their white peers and were taught in more crowded classrooms. Perhaps the greatest difference between the schools, however, was in their curricula. While geometry and biology were taught at the Anglo schools, classes at the Mexican schools focused on teaching boys industrial skills and girls domestic tasks.Many Anglo educators did not expect, or encourage, Chicano students to advance beyond the eighth grade. Instead, the curriculum at the Mexican schools was designed, as one district superintendent put it, to help these children take their place in society.Compare and contrast the Mexican schools to the Anglo schools.
