Eli has a collection of football and baseball cards. In all, he has 360 cards in his collection. Twice the number of baseball cards is 30 less than three times the number of football cards. How many more baseball cards than football cards does Eli have?
Answer:
150 football cards
210 baseball cards
Step-by-step explanation:
b + f = 360
2b = 3f - 30
Change second equation to be: 2b - 3f = -30
Multiply first equation by -2 to get: -2b -2f = -720
Add to get: -5f = -750
f = 150
b = 360-150 = 210
What is the measure of angle CBD? ° What is the length of segment CD? cm Which trigonometric ratio can be used to compare BC to CD using angle CBD? What is the approximate length of BC? cm What is the approximate length of BD? cm
Answer:
Answer: The measure of ∠CBD is 36°. The length of segment CD is 6 cm.
The trigonometric function gives the ratio of different sides of a right-angle triangle. The length of the segment CD will be equal to 12cm (60/5).
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
1. For a regular pentagon, the measure of an internal angle is equal to 108°, therefore, the measure of ∠ABD is 108°.
2. Since the line CB is bisecting ∠ABD, therefore, the measure of the ∠CBD is 54°.
3. The length of the segment CD will be equal to the length of a side of the pentagon, therefore, the length of the segment CD will be equal to 12cm (60/5).
4. The trigonometric ratio that can be used to compare BC to CD using ∠CBD is Tangent.
5. The approximate length of BC can be determined as,
Tan(54°)=CD/BC
BC = CD/Tan(54°)
BC = 8.719 cm
6. The approximate length of BD can be determined using the Pythgorus theorem,
BD² = CD² + BC²
BD = 10.5835 cm

How do you do the Pythagorean Theorem? Also how do you do it with one leg and hypotenuse? Also how do you do it with 2 legs and no hypotenuse?
Answer:
Pythagorean Theorem = a^2 + b^2= c^2
Step-by-step explanation:
(3)^2+ (4)^2 = C
3^2= 9
4^2= 16
9+16=25
(2 legs no hypotenuse)
9^2+ b^2=7^2
9^2 = 81
7^2= 49
81-49= 32
(you have to sqaure root it because the oppsite of sqaured is sqaured root)
32 squared = 5.657
and rounded is 5.7

A function assigns the values. The value of (5r+1/5)² when the value of r is 0 equals 0.04.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function g(r)=(5r+1/5)², therefore, the value of the function when r=0 will be,
g(r) = (5r+1/5)²
g(0) = [5(0)+1/5]²
g(0) = (1/5)²
g(0) = 1/25
g(0)=0.04
Hence, the value of (5r+1/5)² when the value of r is 0 equals 0.04.

The angles of a triangle add up to 180 degrees.
(3x+5)+(2x+17)+(2x+18)=180
add the ones alike
3x + 2x + 2x=7x
5+17+18=40
so, 7x+40=180
we need to get the variable by itself so we take away 40 first by subtracting it from both sides of the equal sign
7x=140
we take away 7 from x by dividing it- opposite of multiplication is division
x=20
Answer:
x = 20
Step-by-step explanation:
3x+5° + 2x+18° + 2x+17° = 180° (sum of interior angles in a triangle is 180°)
collect like terms
3x + 2x + 2x + 5° + 18° + 17° = 180°
7x + 40° = 180°
solving for x
x = (180 - 40)/7
x = 140/7
x = 20

The circumference of the circle is 6.28 yards.
What is circumference of the circle?"It is the length of the boundary of the circle."
Formula to calculate the circumference of the circle:C = 2 × π × r, where 'r' is the radius of the circle.
For given example,
r = 1 yd.
π = 3.14
Using the formula for the circumference of circle,
⇒ C = 2 × π × r
⇒ C = 2 × 3.14 × 1
⇒ C = 6.28 yd.
Therefore, the circumference of the circle is 6.28 yards.

Step-by-step explanation:
Use the graph relations.
Answer:
7.5 lb
Step-by-step explanation:
Look at the points on the graph.
She paid $1 for 1.5 lb.
She paid $2 for 3 lb.
She paid $4 for 6 lb.
She paid $7 for 10.5 lb.
Now divide each amount of lb by each cost.
1.5/1 = 1.5
3/2 = 1.5
6/4 = 1.5
7/10.5 = 1.5
In every case, she got 1.5 lb for each dollar.
On the day she spent $5, she got 1.5 lb for each dollar.
$5 * 1.5 lb/$ = 7.5 lb
Answer: 7.5 lb
