Answer:
300 bags of dog food
Step-by-step explanation:
4b + 2b + b + b = 600
(dog) + (cat) + (bird) + (hamster) = 600
8b = 600
b = 75
Byron purchased 75 bags of bird food. He needs 4 times that of dog food. So, he purchased 300 bags of dog food.
A -foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a angle with a short vertical support.
Complete question :
A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.
What is the length x of a diagonal support, to the nearest tenth of a foot?
Answer:
13.80 feets
Step-by-step explanation:
Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :
To obtain x :
Sinθ = opposite / hypotenus
Opposite = 12.5 feets ; hypotenus = x ; θ = 65°
Sin 65 = 12.5 / x
0.9063077 * x = 12.5
x = 12.5 / 0.9063077
x = 13.792225
x = 13.80 feets

Evelyn bought 60 tickets for rides at an amusement park. Each ride costs 3 tickets, and Evelyn has been on x rides so far. Select all the expressions that show the number of tickets that Evelyn has left.
Answer:
I believe your answer will be E, A, and C
Step-by-step explanation:
If she has 60 tickets and each ride is 3 tickets but she has been on x rides you would do 3x and subtract that from 60.
Answer:
a,c,e
Step-by-step explanation:
60 is the total number of tickets, so b and d are wrong because you are no adding to the total number of tickets.
It costs $2.80 to buy 4 apples. You want to buy 7 apples. How much will that cost?
Answer:
$4.90
Step-by-step explanation:
Answer:
10 dollars
Step-by-step explanation:
4 / 2.80 = 1.42857142857
so that means 1.42857142857 is the cost of one apple.
1.42857142857 x 7 = 10
so your answer is,
it costs $10 for 7 apples.

is the point (1,-3) a solution to the system? show all your work
y>x-1
y >-x+2
Answer:
To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.
- x + 2 = - 1 + 2 = 1
Now - 3 < 1
Thus (1, - 3) is not a solution

Your class wants to raise more than $350 for the Freshman Party and you choose to sell candy and cookies to accomplish this task. You earn $6 on each basket of candy, b, and $3 on each box of cookies, c, that you sell. If the number of boxes of cookies sold is 78, at least how many baskets of candy will you need to sell to reach your goal?
Answer:
16 baskets of candy.
Step-by-step explanation:
78 boxes of cookies times $3 per box equals $234.
$350-$234=$116 left you need to make so-
each basket of candy earns $6, divide $116 by $6 to equal 56.
You will need to sell 56 baskets of candy at $6 each to reach your goal of $350 .

Jim invests $1240 at a 3.6 interest rate in an account that is compounded quarterly. What is the value of the account after 6 years
Answer:
$1507.84
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.6%/100 = 0.036 per year,
then, solving our equation
I = 1240 × 0.036 × 6 = 267.84
I = $ 267.84
The simple interest accumulated
on a principal of $ 1,240.00
at a rate of 3.6% per year
for 6 years is $ 267.84.
Find the measure of angle b
Answer:
26˚
Step-by-step explanation:
Since there is already two angles (The square in the corner shows that the angle is 90˚)
So subtract 90˚ with 64˚ which is 26˚
Answer:
this whole angle is equal to 90°
so the value of angle b = 90°-64°
so the value of b= 26.

Michelle says that the solution to the inequality 2(4y-3) > -22 is y > -3.5.
what was her mistake. What is the solution to the inequality.
Answer:
The solution of the given inequality is y>-2.
Step-by-step explanation:
The given inequality is :
2(4y-3) > -22
Using distributive property on LHS of the above inequality.
8y-6 >-22
Add 6 both sides of the inequality
8y-6+6 >-22+6
8y>-16
y>-2
So, the value of y is more than -2.

Answer:
x= -3/2 or x=1.
Step-by-step explanation:
First, make the equation into a factorable form by subtracting 2 from each side to get 2x²+x-3=0. Then factor that into (2x+3)(x-1)=0. Then, you would do 2x+3=0, 2x=-3, x= -3/2. After that, do the second equation x-1=0, x=1.

Answer:
[tex]x \approx 24\degree [/tex]
Step-by-step explanation:
In triangle BAC, by Pythagoras theorem:
[tex]AC^2 = BC^2 -BA^2 [/tex]
[tex]AC^2 = (15)^2 -(9)^2 [/tex]
[tex]AC^2 = 225 - 81[/tex]
[tex]AC^2 = 144[/tex]
[tex]AC = \sqrt {144} [/tex]
[tex]AC = 12\: cm [/tex]
In triangle ABD,
[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]
[tex] \tan \angle ABD =\frac{5}{9} [/tex]
[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]
[tex] \angle ABD =29.054604099\degree [/tex]
[tex] \angle ABD =29.05\degree [/tex]
Next, in triangle ABC, by sine rule:
[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]
[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]
[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]
[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]
[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]
[tex]29.05\degree+x =53.130102354\degree [/tex]
[tex]29.05\degree+x =53.13\degree [/tex]
[tex]x =53.13\degree- 29.05\degree[/tex]
[tex]x =24.08\degree [/tex]
[tex]x \approx 24\degree [/tex]

Write a reclusive rule for the sequence, then give the next two numbers in the sequence 6,1,7,8,15,23
Answer:
aₙ = aₙ₋₁ + aₙ₋₂
where:
a₁ = 6
a₂= 1.
Step-by-step explanation:
We have the sequence:
6, 1, 7, 8, 15, 23, ...
Is easy to see that this sequence works as follows:
You take 2 consecutive numbers, and the next number is the sum of these two.
Then we have:
6 + 1 = 7
1 + 7 = 8
7 + 8 = 15
8 + 15 = 23
Then the n-th term is equal to the sum of the (n - 1) term and the (n - 2) term.
This is written as:
aₙ = aₙ₋₁ + aₙ₋₂
Because in the recursive rule needs two previous terms, we need to specify the two first terms of the sequence.
Then we need to write also:
a₁ = 6
a₂= 1.
Write down in terms of n an expression for the nth term of the following sequence
