Answer:

John scored 46 points out of 230 points in the test.

Step-by-step explanation:

Number of points achieved by john in the test = 46  

Percentage of points achieved by john in the test = 20%  

Let the total points be x,

Therefore, According to the question: 20% of x = 46 \Rightarrow 0.2x = 46  \Rightarrowx=\frac{46}{0.2}=230\Rightarrow x=230

Hence, total points in the test were 230.

What is the solution to 2x+y=1 and x-2y=3
Masteriza [31]

Answer:

Step-by-step explanation:

2x+y=1---------> y=-2x+1

x-2y=3

2) x-2(-2x+1)=3                          

x+4x-2=3

5x=5

x=1

3) 2x+y=1 when x=1

2(1)+y=1

2+y=1

y=1

the answer is (1,1)

Write a linear function whose slope is -4 and y intercept is -5. Explain what these values mean in the equation.
dsp73
In y = mx + b form, the slope is in the m position and the y int is in the b position.

y = mx + b
slope(m) = -4
y int (b) = -5
y = -4x - 5
or
f(x) = -4x - 5

Tree casts a shadow 30 feet long. A MHS student standing near the tree casts a shadow 9 feet long. The  student is 6 feet tall. What is the height of the tree? Show all work

<em><u>Answer:</u></em>

Option D

The height of tree is 20 feet tall

<em><u>Solution:</u></em>

From given question,

Shadow of tree = 30 feet

Height of tree = ?

Height of student = 6 feet

Shadow of student = 9 feet

We have to find the height of tree

We can solve the sum by proportion

\frac{\text{height of tree}}{\text{shadow of tree}} = \frac{\text{height of student}}{\text{shadow of tree}}

This forms a proportion and we can solve the sum by cross multiplying

\frac{\text{height of tree}}{30} = \frac{6}{9}\\\\\text{height of tree} = 30 \times \frac{6}{9} = 30 \times \frac{2}{3}\\\\\text{ height of tree } = 10 \times 2 = 20

Thus height of tree is 20 feet tall
