Step-by-step explanation:
For every 15 situps Ryan does, he does 10 push-ups. Create a table of equivalent ratios that show the relationship between the number of sit-ups and the number of push-ups Ryan does.
Answer:
15/10, 30/20, 60/40, 120/80, 240/160, 480/320
Step-by-step explanation:
The number of push-ups is 2/3 the amount of sit-ups, so the ratio of sit-ups to push-ups is 3:2.
The easy way to do this is to double both 15 and 10 so your answer will stay an equivalent ratio. You will always have a 3:2 ratio this way.

Answer:
Baking a cake is a chemical change.
Step-by-step explanation:
The baking powder or baking soda will undergo a chemical reaction. The heat helps baking powder or soda produce tiny bubbles of gas which makes the cake light and fluffy. That's why chemical reactions are involved in baking a cake.

Do you want to buy the 101 disc CD charger for 108 and also the digital camera for 364 if the sales tax is 6.5 what is your after-tax total
Answer: 441.32 currency units
Step-by-step explanation:
The CD changer costs 108 currency units and the Camera costs 364 currency units.
First add these up to find out the total price:
= 108 + 364
= 472 currency units
The sales tax is 6.5% and this needs to be deducted from the total to get the after-tax total:
= 472 * ( 1 - 6.5%)
= 441.32 currency units

sec 330 find the exact value in simplest form with a rational denominator
Answer:
[tex]\implies \sec 3 30^o = \dfrac{2}{\sqrt3}=\dfrac{2\sqrt{3}}{3}[/tex]
Step-by-step explanation:
Given :-
[tex]\sec 330^o [/tex]And we need to find out its value . Firstly we know that 330° lies in 4th quadrant . And In fourth quadrant , cosine and secant are positive . Therefore , the result will be positive. Now we know that ,
[tex]\implies \sec (360^o-\theta)= \sec\theta [/tex]
Using this ,
[tex]\implies \sec (330^o) \\\\\rm\implies sec(360^o-30^o) \\\\\rm\implies \sec 30^o [/tex]
And the value of sec 30° is ,
[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}[/tex]
And by question we need to write it with a rational denominator .So on rationalising the denominator , we have ,
[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}=\boxed{\red{\dfrac{2\sqrt3}{3}}}[/tex]
Hence the required answer is 2√3/3.

jona is b kg weight.her mother is seven kg less than three time than jona weight.how old is mother?
Answer: (3b - 7)kg
Step-by-step explanation:
Jona's weight = b kg
Since Jona's mother's weight is seven kg less than three time than jona's weight. This will be:
= (3 × b) - 7
= 3b - 7
Therefore, the mother is (3b - 7)kg
Find all the zeros of the function: f(x) = x^2 - 2x - 3
Answer:
x= 3 and -1
Step-by-step explanation:
[tex]f(x) = {x}^{2} - 2x - 3[/tex]
add three to both sides
[tex]3 = {x}^{2} - 2x[/tex]
figure out what half of -2 is
half of -2 is (-1) than square that (-1)^2=1
the 1 is what you add to both sides
[tex]3 + 1 = {x}^{2} - 2x + 1 \\ 4 = {(x - 1)}^{2} [/tex]
than take the square root of both sides
[tex] \sqrt{4} = \sqrt{ {(x - 1)}^{2} } [/tex]
this than equals
+2=x-1
than to find the x values
2=x-1
+1 +1
3=x
-2=x-1
+1 +1
-1=x

The value of a new car decreases by 10% in the first year.How much will a car be worth after one year if it’s an initial value was $40,000?
Answer:36,000
Step-by-step explanation: if ten percent of 100 is 10 we can use the same concept on 40000 by dividing it by 10 because 10% can be roughly said as 1/10 so 1/10 of 40000 is 4000 which we will subtract 40000 by which results in 36000
Hope this can help you
Use the graph of the function,
f(x)=x-1/x^2+5x+6
to identify the function's
vertical asymptotes.
a. x=-1, x= 6
b. x=1, x=-6
c. x=-2, x=-3
d. X= 2, x= 3
Answer:
c. x = -2 or x = -3
Step-by-step explanation:
The vertical asymptotes occur where the denominator = 0. That happens when the f(x) is undefined. So,
x^2 + 5x + 6 = 0
(x + 2)(x + 3) = 0
x = -2 or x = -3
Which angles are adjacent to BFD? Select all that apply.
Answer:
<AFB
Step-by-step explanation:
First you must know the two adjacent angles are placed side ways in a diagram. Most of this angles are supplementary i.e their sum is 180 degrees. From the diagram shown, you can see that the two angles that are supplementary are <BFD and <AFB. Hence we can conclude that <AFB is adjacent to <BFD
Find the area of the figure.
plz i give brainliest.
Answer:
23.5 inches^2
Step-by-step explanation:
Area of triangle = 1/2 * base * height
area = 1/2 * (5+2) * (5+4)
area = 31.5 in^2
Area of rectangle = length * breadth
area = 4 * 2
area = 8 in^2
Area of figure = area of triangle - area of rectangle
area = 31.5 - 8
area =23.5 in^2

What is the first step in solving this equation ? y + 7 = 18
Answer:
subtract 7
Step-by-step explanation:

You need to get the y by itself, so you subtract 7 to cancel it out.
y+7=18
-7 -7
y=11
