You are going to make cookies for a party. The recipe requires 3 cups of flour, 2 cups of chocolate chips and other ingredients. I also need to write an equivalent ratio that shows how much you need to double the original recipe, can someone help?
Answer:
Ratio of flour to chocolate = 6 : 4
= 3 : 2
Step-by-step explanation:
Original recipe
Flour = 3 cups
Chocolate = 2 cups
Ratio of flour to chocolate = 3 : 2
To double the original recipe
Flour = 3 cups × 2
Chocolate = 2 cups × 2
Flour = 6 cups
Chocolate = 4 cups
Ratio of flour to chocolate = 6 : 4
= 3 : 2

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.
Answer: [tex]w = 10[/tex]
Step-by-step explanation:
Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.
Step 1: Let 6w will be our length and let the perimeter be 140 cm.
[tex]6w, P = 140 cm[/tex]
Step 2: Perimeter means that you add up all the 4 sides of the rectangle.
[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]
[tex]P = 140, 14w[/tex]
Step 3: Divide both sides 14 to get the single w variable.
[tex]\frac{140}{14} = \frac{14w}{14}[/tex]
Step 4: Simplify.
[tex]10 = w[/tex]
Step 5: Flip sides.
[tex]w = 10[/tex]

It’s a 5 hour flight and she lives 3060 miles from you. How fast did the plane go?
Answer:
612
Step-by-step explanation:
the choice selections are 3.2m
5.0m
8.7m
and 11.2 m
Answer:
8.7m
Step-by-step explanation:
Use the Pythagorean theorem, a^2 + b^2 = c^2
a and b are the sides going either horizontally or vertically, it doesn't matter which is which as long as it's only between those 2.
c is the diagonal side, also called the hypotenuse.
so plug in:
a^2 + b^2 = c^2
5^2 + b^2 = 10^2
25 + b^2 = 100
subtract 25 from both sides
b^2 = 75
square root both sides
[tex]\sqrt{b^2} = \sqrt{75}[/tex]
b = 8.66, round it up and it's 8.7
Jose buys a bike for $185.00. He used a coupon that saved him 20%, how much did Jose pay for the bike?
Answer:
he paid $37 is the answer for the question
9514 1404 393
Answer:
$148
Step-by-step explanation:
The coupon saved ...
0.20 × $185 = $37.00
When that amount is subtracted from the $185 price, the amount is ...
$185 -37 = $148
Jose pays $148.
_____
Comment on the wording
It seems the question answers itself in the first sentence. Jose bought the bike for $185. If that is what he bought it for, that is what he paid.
We assume the intended wording is something like, "Jose bought a bike with a marked price of $185."
3) Write an equation of a
line that has a slope of -3
and goes throughh
the
point (-4, 6)
m = -3
point = (-4,6)
You need to put this in point slope form.
y - 6 = - 3( x + 4 )
distribute
y - 6 = -3x - 12
add 6 to 12
y = -3x - 6
answer : y=-3x-6

Please help I don’t understand
Answer:
[tex]y=-3\sqrt{x} +8[/tex]
Step-by-step explanation:
The question is asking you to write a function from the original function ([tex]\sqrt{x}[/tex]) w/ the given conditions.
It wants you to make a function that reflects over the x-axis; should be mirrored with the original function.
y=-[tex]\sqrt{x}[/tex] does just that.
Then it wants a horizontal stretch by 3.
[tex]y=-3\sqrt{x}[/tex]
Then move that graph up by 8 units.
[tex]y=-3\sqrt{x} +8[/tex]
Please know the transformation rules for functions to understand what you are doing better.
For a field trip, a bus company charges $100 plus a fee per student. The total cost is $350.00 for 70 students. Which equation models the total cost, y, of the field trip for x number of students?
what is the scale factor
Answer:
2/5
Step-by-step explanation:
Since it's from a big square to a smaller square, the smaller number will be at the top. Also, use the same side to find the scale factor, but since this is a square and all sides of a square are equal, it doesn't matter but in other shapes it does so practice i guess:
Left side of big square: 5
Left side of small square: 2
So scale is 2/5
To confirm:
5 · 2/5 = 10/5 = 2, we're right
QUESTION Lin’s father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied.
how much does lin father pay for the meal
Answer:
18.19
Step-by-step explanation:
First we must determine how much 15% of 20 is (3). Now we must subtract that from 20 (20-3=17$) Once we have that we must figure out how much 7% of 17 is ($1.19) Lastly, we must add the tax to 17.00 (17+1.19) to get 18.19.

Step-by-step explanation:
Polina the Polar Bear sat on an ice floe in the Arctic Ocean, north of Alaska. Polina was waiting for her mother, Bearnice, to return hwith some tasty seal blubber for lunch. Bearnice was hunting, waiting for seals to come up for air through holes in the ice, the same way Polar Bears have hunted in the winter for centuries. Except this year there was one big difference.
A lot more of the ice had melted last summer, and this winter it hadn’t refrozen as usual. A combination of warmer weather and changes in water and air currents was making the ocean warmer than anyone could remember, and Bearnice had to swim farther every day to find a good hunting spot.
As Polina waited for her mother to bring food back to her floe, the ice shrank bit by bit until she was sitting on very thin ice. As Polina waited helplessly, the furry white cub heard a deep voice coming from the direction of the sea.
“Hellooo little bear,” it said. Polina had never heard such a deep voice. She lifted her tired head to look out over the water, and was surprised that the voice seemed to come from a dark ice floe just offshore.
"No, wait!" It had a huge eyeball that was looking directly at her. It wasn’t an ice floe — it was the largest whale Polina had ever seen. It was also the first whale that had ever spoken to her.
“They call me Farswimmer,”said the whale, “because I travel all over the world, having adventures and learning new things. What brings you here alone, Polar Bear?” Farswimmer was very old, and he had seen many changes in his years of exploring the oceans. He certainly knew more about the world than most polar bears.
Farswimmer seemed like a nice whale, but Polina remembered Bearnice, her mother, and how she hadn’t come back from hunting.
Farswimmer blew a tall spout to distract Polina and stop her from crying.
When Polina told the whale her own story, he said, “I’m headed north anyway. You could ride on my back, and we can look for your mother. Are you ready for an adventure?” The next morning, Farswimmer and Polina charted their course and took off. Polina rode Farswimmer’s back and sometimes floated behind him, holding his tail. She also stood on his back and pretended she was surfing. It was a blast.
They took a break on an ice floe. Soon, they saw something in the distance that looked like another ice floe, but just to be sure, Farswimmer left Polina on the ice and swam to the floating object.
It wasn’t an object. It was an animal. Farswimmer used his fat nose to push the animal to Polina’s icy raft. When they got closer, Polina saw a familiar face.
“Mommy,” she yelped. Bearnice was very tired, but the sound of her cub’s voice made her happy. She opened her arms and the two embraced each other in a big bear hug.

Katie has a savings account that contains $230. She decides to deposit $5 each month from her monthly earnings for babysitting after school. Write an expression to find how much money Katie will have in her savings account after x months. Let x represent the number of months.
Given:
Initial savings in Katie's account = $230
Additional savings = $5 per month
To find:
The expression that represents the money Katie will have in her savings account after x months.
Solution:
Let x be the number of months.
Additional savings for 1 month = $5
Additional savings for x months = $5x
Now,
Total savings = Initial saving + additional savings for x months.
[tex]\text{Total savings}=230+5x[/tex]
Therefore, the required expression is [tex]230+5x[/tex].
