Malachy, Sushil and Fiona share some sweets in the ratio 7:1:1. Malachy gets 90 more sweets than Fiona. How many sweets does Sushil get?
Answer:
15
Step-by-step explanation:
Fiona (F) = Sushi (S)
Malachy (M) = 7 Fiona (F)
M = F + 90
F + 90 = 7F
6F = 90
F (Fiona) = 15
S (Sushi) = 15
check: Malachy (M) = 15 * 7 = 105
M-F = 105 - 15 = 90
Many families in California are using backyard structures for home offices, art studios, and hobby areas as well as for additional storage. Suppose that the mean price for a customized wooden, shingled backyard structure is $3,200. Assume that the standard deviation is $1,200. (a) What is the z-score for a backyard structure costing $2,300
Answer:
-0.75
Step-by-step explanation:
To get the z score we have to use this formula
Z = X-mean/standard deviation
X = 2300
Mean = 3200
The standard deviation = 1200
When we plug these values into the z formula above, we have:
2300-3200/1200
= -900/1200
= -0.75
the z-score for a backyard structure costing $2,300 is therefore -0.75

1. Classify the following triangles according to their (1) sides and (ii) angles,
(fig 1) A=8cm b=5cm c=8cm
Answer:
Isosceles triangle
Step-by-step explanation:
The given sides of a triangle are 8 cm, 5 cm and 8 cm.
We need to say that the type of triangle.
The two sides of a triangle are same i.e. 8 cm and the other side is 5 cm.
Such type of triangle in which two sides are equal, the triangle is isosceles. Here, two sides are 8 cm and the third one is 5 cm. It means the triangle is an isosceles triangle.

Use the distributive property to multiply.
-(-16m-1)
Answer:
16m+1
Step-by-step explanation:
Knowing about our proprieties about parentheses and negatives, let's solve this out.
A negative multiplied by a negative give you a positive
therefore....
-(-16m-1)= 16m+1
The -1 also receives the negative because the problem was in a parentheses :)

The formula for calculating your credit utilization ratio is pretty straightforward. To figure it out for an individual card, divide your credit card balance by your available credit line.
What you you do is divide the credit card ratio for each one.
For the first card: $2,397 (total on card) divided by 16,000, (the limit) is 0.149, we round that to 0.15. (15%)
For the second card: $1,218 (total on card) divided by 5,500 (the limit) which is 0.221. We round that to 0.22. (22%)
The question asks for the OVERALL, and that means to add. 22+15=37.
what is the answer to 3(x-4)=12 in simplest form ?
Answer:
x = 8
Step-by-step explanation:
You distribute the 3 to x and -4.
[tex]3x-12=12[/tex]
You add 12 to both sides.
[tex]3x=24[/tex]
Then you divide by three on both sides.
[tex]\frac{3x}{3}=\frac{24}{3}\\[/tex]
[tex]x=8[/tex]

Solve for the missing side to the nearest tenth.
16
30
X =
Answer: x=32
Step-by-step explanation:
Because a triangle is 180°, the missing angle in the triangle would be 60°.
Because of the 30°-60°-90° angles theorem, The side opposite 90° is double the side opposite 30°, which means that x=32.
Hello! :)
Please help me solve this + explain your answer :)
I will indeed give you Brainlst <3
Answer:
A
Step-by-step explanation:
The two triangles are congruent because if each triangle's angles add up 180 degrees, you can deduce that the triangles have atleast two congruent angles.
Triangle RST:
48 + 73 = 121
180 - 121 = 59
Angle R = 59
Angle T = 48
Angle S = 73
59 + 48 + 73 = 180
Triangle ABC:
73 + 59 = 132
180 - 132 = 48
Angle A = 59
Angle B = 73
Angle C = 48
59 + 48 + 73 = 180

Answer:
the green line
Step-by-step explanation:
its closest to the point
Hi there! The answer would be the green line and the dark blue line which is f(x)=2x+3 and h(x)=-2x+2.
Step By Step:
So you need to figure out the line for (2,-2).
This means that you would have to find a line that is between them which is the correct answer.
Well it can’t be orange since that it didn’t touch it and so can it not be red. So we have two answers left to choose from.
The last two pairs we have left would be the answer since they’re nothing touching the point for (2,-2).
This means that it would be D, dark blue and orange, or we can say f(x)=2x+3 and h(x)=-2x+2.

You have 7 cups of raisins. A recipe calls for 2/3
cup of raisins per serving. How many full servings can you make?
Answer:
10 servings
Step-by-step explanation
7 cups is equal to 21/3 cups. Since 21 isnt divisible by 2, you have to round down to the nearest divisible number, which would be 20. 20/2 is 10, so 10 is the answer.

Step-by-step explanation:
Convert 3 weeks to hours. Use a lable.
Answer: 504 hours.
Step-by-step explanation: I am assuming it says, use a table not a lable.
Well, I can't make a table, so I will tell you where to put everything in a table.
We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.
24 x 7 = 168 and 1 x 7 = 7
So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by the 3 weeks. So we multiply 168 by 3 which is 504.
So 504 hours are in 3 weeks.
