Marry had 22 3/4 grams of salt. She used 7 1/4 grams to make spinach omelets and 4 7/8 grams to make mushroom omelets. About how much salt does Marry have left? Choose the best estimate.
Answer:
10 5/8
Step-by-step explanation:
We need to subtract (7 1/4 + 4 7/8) from 22 3/4 grams of salt.
We compute the whole numbers and fractions separately:-
7 + 4 = 11
1`/4 + 7/8 = 2/8 + 7/8 = 9/8 = 1 1/8.
So 7 1/4 + 4 7/8 = 12 1/8
Therefore:-
22 3/4 - 12 1/8
22 - 12 = 10
3/4 - 1/8 = 5/8
= 10 + 5/8 = 10 5/8 (answer)
Given that SU≅UT and SV>VT, identify a two-column proof that proves m∠SUV>m∠TUV.
Answer: Choice B
We start with SU = UT being given, and so is SV > VT.
The second line is UV = UV by the reflexive property to help us use the converse of the hinge theorem next.
The hinge theorem basically says that the more open an angle is, the larger the opposite side will be (the side opposite from the angle that varies). Imagine a door opening and closing. The further open it gets, the longer the rope will be that connects the door handle to the frame. Going in reverse, the converse says that if the opposite side of the angle gets bigger, then the angle itself gets bigger as well. The hinge theorem is handy to help compare two sides even if we don't know their exact lengths (we can figure out which side is larger than the other)
The conditions given that SU is congruent to UT and SV is greater than VT create a scenario where we can prove that the measure of angle SUV is greater than the measure of angle TUV.
Explanation:Given that SU≅UT means that segment SU is congruent to segment UT, and SV>VT meaning that segment SV is greater than segment VT, this sets up two important conditions for the triangle SUV. First, as SU is congruent to UT, this implies that ∠SUV is congruent to ∠TUV due to the Base Angles Theorem (If two sides of a triangle are congruent (equal), then angles opposite these sides are congruent). However, SV>VT creates an inequality which contradicts this, pointing towards the fact that ∠SUV is greater than ∠TUV.

What is the scale factor of △UVW to △ XYZ?
Answer:
B. 1/7
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are the same.
... UV/XY = 3/21 = 1/7 . . . . . matches B
_____
When we talk about the ratio "A to B", we usually mean A:B or A/B. There's the possibility that the question could be interpreted to mean, "what factor do I multiply by to get from A to B?" In that case, the result here would be 7, because XY is 7 times the length of UV.

Alice paid $21.75 for some packs of rice crackers. If each pack costs $1.75, how many packs did she buy?
We have dollars and dollars per pack, so we divide to get how many packs.

Odd that it's not a whole number of packs; please check the question carefully. Let's say she bought 12 and got some change.
My guess is the question really says Alice spent $22.75, so she bought 13 packs. Again check the question carefully. You don't need us to divide two numbers.

The price of gold is often reported per ounce. At the end of 2005, this price was $513. At the end of 2015, it was $1060. By what percentage did the price per ounce of gold increase?
Answer:
106.63%.
Step-by-step explanation:
We have been given that at the end of 2005, this price was $513. At the end of 2015, it was $1060.
To find the percentage of the price per ounce of gold increase we will use % increase formula.
[tex]\text{Percent Increase}=\frac{\text{Final value-Initial value}}{\text{Initial value}}\times 100[/tex]
Let us substitute our given values in above formula.
[tex]\text{Percent Increase}=\frac{1060-513}{513}\times 100[/tex]
[tex]\text{Percent Increase}=\frac{547}{513}\times 100[/tex]
[tex]\text{Percent Increase}=1.0662768031189084\times 100[/tex]
[tex]\text{Percent Increase}=106.62768031189084\approx 106.63[/tex]
Therefore, the price of per ounce of gold increased by 106.63%.
Answer:107
Step-by-step explanation:
So if it is incorrect for the other answer this is the answer, so do 1060-513=547, so it increased by that much, then divided 547/513= 1.06627680312 But that rounds up to 7 and since we know that the original was 100% of its amount we would add 100+7 which would be 107%

Each CD in a store costs $10, and each book costs $6. If you want to spend exactly $32, write an equation in standard form modeling this situation. Let c represent the number of CDs you buy, and b represent the number of books you buy.
Final answer:
To model the situation with an equation, use the quantities of CDs and books as variables c and b, and their prices to create the equation 10c + 6b = 32, which represents spending exactly $32.
Explanation:
To create an equation modeling the situation where you want to spend exactly $32 on CDs and books, we need to use the given prices for each item. Let c represent the number of CDs you buy at $10 each, and let b represent the number of books you buy at $6 each.
The total amount spent will be the sum of the amount spent on CDs and the amount spent on books. Using the price of each item, we can write the following equation:
10c + 6b = 32
This equation can now be written in standard form, which is Ax + By = C, where A, B, and C are integers, and A is non-negative. Therefore, our equation in standard form is:
10c + 6b = 32

The graph of an absolute value function opens down and has a vertex of (-3,0).
The domain of the function is ?
The range of the function is ?
The domain of the function is:
All real numbers i.e. (-∞,∞)
The range of the function is:
(-∞,0]
Step-by-step explanation:It is given that:
The graph of an absolute value function opens down and has a vertex of (-3,0).
This means that the graph of the function increases continuously in the interval (-∞,-3] and takes maximum value 0 when x= -3 and then decreases continuously in the interval (-3,∞).
Domain of a function--
It is the set of all the x-values for which a function is defined i.e. it is the set of all the values of the independent variable for which the function is defined.
Range of a function--
It is the set of all the values attained by a function.
We know that a absolute value function is defined all over the real line i.e. the domain of the function is the set of all the real values i.e. (-∞,∞).Also, the function takes all the value between -∞ and 0 and 0 is included.Hence, the range of the function is: (-∞,0].
The length of a rectangular is 5 centimeters less then it width. The perimeter of the rectangle is 26
Hi there! :)
Answer:
Length = 4 cm
Width = 9 cm
Step-by-step explanation:
Here's the information we know:
- Perimeter = 26 cm
- Width = x (I just replaced the width by "x" because it's what we are looking for)
- Length = x - 5
Now before we can do anything, you need to know what the formula for the perimeter of a rectangular is: P = (2 × Length) + (2 × Width)
Replace all the information you know in the formula and solve the equation by isolating "x":
P = (2 × Length) + (2 × Width)
26 = ( 2 × (x - 5)) + (2 × x)
Multiply "2" and "x" together → 2 × x = 2x
26 = ( 2(x - 5)) + 2x
Distribute the "2" to the entire parentheses → 2 × x = 2x & 2 × -5 = -10
26 = 2x - 10 + 2x
Add similar terms together → 2x + 2x = 4x
26 = 4x - 10
Add 10 to each side of the equation → 26 + 10 = 36
36 = 4x
Divide each side of the equation by 4 → 36 ÷ 4 = 9
9 = x ⇒ Measure of the width
Since the lenght is 5 centimeter less than the measure of the width, in order to find the measure of the length you'll need to subtract "5" from the measure of the width, which is "9":
9 - 5 = Length rectangle
9 - 5 = 4 ⇒ Length rectangle
There you go! I really hope this helped, if there's anything just let me know! :)

Triangle QRS is dilated about the origin by a scale factor of 2/3 to create triangle ABC . Are the two triangles congruent?
Answer:
No
Step-by-step explanation:
In a dilation, size is not preserved. Triangles must have the same shape and size in order to be congruent. If it is dilated by 2/3, then it gets smaller, and is therefore not the same size.
Final answer:
Triangle QRS is not congruent to triangle ABC after a dilation of [tex]\frac{2}{3}[/tex], but the two triangles are similar because their corresponding angles are equal and sides are proportional.
Explanation:
The question concerns the concept of congruent and similar triangles in geometry. When triangle QRS is dilated about the origin by a scale factor of [tex]\frac{2}{3}[/tex] to create triangle ABC, the two resulting triangles are not congruent because their corresponding sides are not equal in length. However, they are similar since the angles remain the same and the sides are proportional. Congruent triangles are identical in both shape and size, but similar triangles maintain the same shape while the size can vary in proportion.
