5. 2.5 x + 20 = 25
Answer:
x= 2
Step-by-step explanation:
Subtract 20 from both sides
2.5x + 20 − 20 = 25 − 20
2.5x= 5
Divide both sides by 2.5
2.5x/2.5= 5/2.5
x= 2
help with finding g(f(x))
f(x) = x squared - 3x + 2
g(x)= x+2
Answer:
=x+2
Step-by-step explanation:
Answer:
g(f(x)) = x² - 3x + 4
Step-by-step explanation:
Substitute x = f(x) into g(x) , that is
g(x² - 3x + 2)
= x² - 3x + 2 + 2
= x² - 3x + 4

The freshman class of 175 students went on a field trip. For transportation, they needed both vans (which hold 5 students each) and buses (which hold 35 students each). There was a total of 11 vehicles used.
How many of each type of vehicle did they use?
Vans: _________________
and
Buses _________________
.
Answer:
You will need 7 vans and 4 buses
Step-by-step explanation:
7 vans would take care of 35
4 buses would take care of 140 kids
and it uses a total of 11 vehicles
Hope this helps
Answer:
Vans = 7
Buses = 4
Step-by-step explanation:
x = vans
y = buses
x + y = 11 (1)
5x + 35y = 175 Divide this equation by 5
x + 7y = 35 (2)
============
Subtract (1) from (2)
x + 7y = 35
x + y = 11
6y = 24 Divide by 6
6y/6 =24/6
y = 4
===========
x + y = 11
x + 4 = 11
x = 11 - 4
x = 7
Now Let's check it
x is the number of vans which holds 5 students each
7 * 5 = 35
y is the number of buses which holds 35 students each
4 * 35 =140
Total number of students = 35 + 140 = 175
So it checks.

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.
Answer:
140.6 feet
Step-by-step explanation:
In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.
Step 1
We have to find Angle M
Sum of angles in a triangle = 180°
M + N + O = 180°
M = 180° - ( N + O)
M = 180° - ( 90° + 62°)
M = 28°
Step 2
We find the length of MN
We solve using Sine rule
MN/sin O = NO/sin M
MN/sin 90 = 66/sin 28
Cross Multiply
MN = sin 90 × 66/sin 28
MN = 140.58 feet
Approximately = 140.6 feet

Determine the independent variable in the statement:
The longer April exercises, the more calories she burns.
1.Time spent exercising
2.Calories burned
Answer:
1
Step-by-step explanation:
because when April stops exercise the calories burnt will reduce
Answer:
it's Time spent exercising.
Step-by-step explanation:
Time spent exercising does not rely on calories burned for its value to change. However, the time spent exercising will determine how many calories are burned. This shows that calories burned is dependent on time spent exercising while time spent exercising is an independent variable.

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 6x
Explaination:
slope intercept form is just y=mx+b, and since the slope is 6, you plug 6 into m, and then the y-intercept is 0, so you can drop it out of the equation

After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand. Model this situation by writing an equation of the form c(t)=mt+b where c is the number of copies still on hand after t days of being available
Answer:
[tex]c(t) =-18t +212[/tex]
Step-by-step explanation:
Given
[tex](t_1,c_1) = (4,140)[/tex]
[tex](t_2,c_2) = (9,50)[/tex]
Required
Determine the equation
First, we calculate the slope (m)
[tex]m = \frac{c_2 - c_1}{t_2 - t_1}[/tex]
[tex]m = \frac{50 - 140}{9-4}[/tex]
[tex]m = \frac{-90}{5}[/tex]
[tex]m = -18[/tex]
The equation is then calculated as:
[tex]c =m(t - t_1) + c_1[/tex]
[tex]c =-18*(t - 4) + 140[/tex]
[tex]c =-18t +72 + 140[/tex]
[tex]c =-18t +212[/tex]
Hence, the function is:
[tex]c(t) =-18t +212[/tex]

aurora scored 572 marks out of 650 belle scored 450 out of 500 for the annual examination.
a. who performed better and by how much.
b .what percentage she scored
Step-by-step explanation:
a. Belle as she only missed 50 questions where as Aurora missed 78. (500-450) and (650-572)
b. Belle scored 90% (450/500=0.9)
Answer:
a. Belle scored better, by scoring 2% more than Aurora.
b. She scored 90%
Step-by-step explanation:
Make your denominator out of a 100
So you will divide by 6,5
572÷6,5/650÷65
= 88/100
=88%
And divide the other by 5
450÷5/500÷5
=90/100
=90%

Answer:

The value of measure of angle R is,
⇒ m ∠R ≈ 22.62°
What is mean by Angle?An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Reference angle = R
Side opposite to R = 5 cm
Adjacent side length = 12 cm
Thus, applying TOA, we have:
Tan R = opposite/adjacent
Tan R = 5/12
R = tan⁻¹ (5/12)
R ≈ 22.62°
Thus, The value of measure of angle R is,
⇒ m ∠R ≈ 22.62°

Find the Total surface area
A prism 11 in tall with a right triangle for a base with side lengths 6 in, 8 in, and 10 in.
A) 344 in2
B) 383 in2
C) 312 in2
D) 288 in2
Answer:
You may not recognize this...but the base forms a "Pythagorean" right triangle with legs of 6 and 8 cm
The area of a right triangle is (1/2) ( product of leg lengths)
So...the area of the base = (1/2) (6 * 8 ) = (1/2) 48 = 24 cm^2
And the volume of the prism is just the base area x height = 24 x 7 = 192 cm^2

Step-by-step explanation:
convert 16% to a decimal and multiply to find how much discounted then subtract that from the initial value

Answer:
$7.20
$0.636
$27.50
$53.3333333333
Step-by-step explanation:
16% × $45 = $7.20
8% × $7.95 = $0.636
$5.50 = 20%
20% × 5 = 100%
$5.50 × 5 = $27.50
$16 = 30%
30% × 3 and 1/3 = 100%
