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?
Answers
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
The radius of a circle is 1 yard. What is the circle's circumference?
r=1 yd
Use 3.14 for .
Answers
2 x 3.14 x 1
Circumstance = 6.28 yd
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.

You invite your best friend Sheila out for a picnic on Thursday. Sheila tells you "If it rains, there is a 20% probability
that I will come, but if it's sunny, there is an 80% probability that I will come." You check the weather and see that
there is a 40% chance of rain for that day. What is the overall probability that Sheila will attend your picnic? Explain
how you found your answer.
Answers
Answer: 56%
Probably that it will rain and she goes + probably that it will be sunny and she goes

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
Answers
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

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
