Yolanda participated In a walkathon in which each kilometer walked raised $10 for charity, her goal was to raise more more than $300 on Saturday and Sunday she raised $50 on Saturday which inequality is it?

Answers

x= amount of money needed on sunday

50+x(greater or equal to)300

Answer: The required inequality will be 50+x>$300

Step-by-step explanation:

Since we have given that

Amount raised for charity = $10

Amount raised on Saturday = $50

Amount raised on both Saturday and Sunday is more than $300.

Let the amount raised on Sunday be 'x'.

So, Inequality becomes,

Saturday + Sunday > $300

50+x>$300

x>$300-$50

x>$250

So, On Sunday he must raised more than $250.

Hence, the required inequality will be

50+x>$300

Claire's backyard is in the shape of a rectangle and has a length of 19.5 feet it cost her 945 to fence in the yard if fencing costs 15 per foot what is the width of Claire's backyard

Answers

If Claire's backyard is in the shape of a rectangle and has a length of 19.5 feet it cost her 945 to fence in the yard if fencing costs 15 per foot, then the width of Claire's backyard would be 12 feet.

To find the width of Claire's backyard, we'll first calculate the perimeter of the rectangle using the given length and the total cost of fencing. Then, we'll use the perimeter to find the width.

The perimeter of a rectangle is given by the formula:

[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]

Given that the length of Claire's backyard is 19.5 feet and the total cost of fencing is $945 at $15 per foot, we can calculate the perimeter using the cost of fencing:

[tex]\[ \text{Perimeter} = \frac{\text{Total cost}}{\text{Cost per foot}} \][/tex]

[tex]\[ \text{Perimeter} = \frac{945}{15} = 63 \text{ feet} \][/tex]

Now, we'll use the perimeter formula to find the width:

[tex]\[ 63 = 2 \times (19.5 + \text{Width}) \][/tex]

Divide both sides by 2:

[tex]\[ 31.5 = 19.5 + \text{Width} \][/tex]

Subtract 19.5 from both sides:

[tex]\[ \text{Width} = 31.5 - 19.5 = 12 \text{ feet} \][/tex]

So, the width of Claire's backyard is 12 feet.

The complete question is:

Claire's backyard is in the shape of a rectangle and has a length of 19.5 feet it cost her 945 to fence in the yard if fencing costs 15 per foot what is the width of Claire's backyard

Sandy's orchard has only apple trees and pear trees and she is wanting to add some avocado trees. Currently, there are 4 apple trees for every 3 pear trees. She is wanting to plant enough avocado trees so that she has 2 avocado trees for every 5 pear trees in the orchard.
Sandy is planting 18 avocado trees, making the ratio of avocado trees to apple trees be to .

Answers

For every 3 pears there are 4 apples; therefore 1 pear = 1.33 apple.And in every 5 pears, there are 2 avocados; therefore 1 avocado = 2.5 pears.Since there are 18 avocado trees, the number of pears would be 45 pear trees. And since there are 45 pear trees, there will be 59.85 apple trees, rounding it off to 60 apple trees. So the ratio of avocado trees to apple trees would be 18 to 60 or 18: 60.

a recipe calls for 4 tsp of baking soda and 1 fl oz of vanilla which measurment is greater?

Answers

In this problem, you are asked to compare two measurements in different units of measure. The first step to solve this problem is to make the other measurement have the same unit of measure as the other one. You convert 4 tablespoon to fl oz.

1 tsp = 0.5 fl oz

4 tsp = 2 fl oz

Comparing the two measurements, you can conclude that the 4 table spoon (equivalent to 2 fl oz) of baking soda is greater than 1 fl oz of vanilla.

stacy has hired tom to build her a doll house. The doll house will be a scale model of her home, and the scale will be 2 inches:3ft. The living room in stacy's house is 18 feet by 12 feet and has wall-to-wall carpeting. Hiw many square inches of carpeting will Tom need for thevliving room in Stacy's doll house?

Answers

Final answer:

To find the area of the living room in Stacy's doll house, we need to use the given scale of 2 inches:3ft.

Explanation:

To find the area of the living room in Stacy's doll house, we need to use the given scale of 2 inches:3ft. First, we convert the dimensions of the living room from feet to inches. The dimensions of the living room in inches will be 18 feet * 12 inches/foot = 216 inches by 12 feet * 12 inches/foot = 144 inches.

Next, we multiply the dimensions by the scale factor of 2 inches:3ft. The dimensions of the living room in the doll house will be 216 inches * (2 inches/3ft) = 144 inches and 144 inches * (2 inches/3ft) = 96 inches.

Finally, we multiply the dimensions together to find the area: 144 inches * 96 inches = 13,824 square inches.

What is the slope of this line?

Answers

Hello!

To find slope, calculate the change in y-values and divide it by the change in x-values:

y1 - y2 / x1 - x2

You have the coordinates (-4, 5), (0, 6), and (8, 8). You can use any combination of two of these points to calculate slope. I'll use (0, 6) and (8, 8).

6 - 8 / 0 - 8
-2 / -8
1/4

Answer:
The slope of the line is 1/4
Hello there! Slope is rise/run. The formula for finding slope is y2 - y1/ x2 - x1, where you subtract the first x and y-coordinates from the second s and y-coordinates. We will use the points (0, 6) and (8, 8). The values will represent each of these:

y2 = 8
y1 = 6
x2 = 8
x1= 0

That makes the problem 8 - 6/ 8 - 0. Let's subtract. 8 - 6 is 2. 8 - 0 is 8. 2/8 is 1/4 in simplest form. There. The slope of the line is 1/4.

the answer choice: Five of Jainie's friends are selected and asked for whom they intend to vote is the right answer because friends tend to be bias.

The polling methods likely to be biased are when Option d. Five of Janine's friends are selected and asked for whom they intend to vote.

When conducting a poll, it is important to ensure the sampling method is random and representative. Here are the methods and their potential biases:

Janine chooses 5 members that plan on voting for her and asks each to select another 5 members. These 25 members are asked for whom they intend to vote. — This method is likely to be biased because it relies on the initial selection of supporters, which creates a non-random and unrepresentative sample.Every 10th club member from a list of all members is selected and asked for whom the member intends to vote. — This method is less likely to be biased as it uses systematic sampling, which is more representative of the entire population.From a list of all club members, 25 members are selected at random and asked for whom they intend to vote. — This method is unlikely to be biased because it employs a simple random sample, ensuring each member has an equal chance of being selected.Five of Janine's friends are selected and asked for whom they intend to vote. — This method is likely to be biased due to the convenience sampling of her friends, which is not representative of the entire club.

What series of transformations to quadrilateral ABCD map the quadrilateral onto ​ quadrilateral EFGH to prove that ABCD≅EFGH ?




a reflection across x-axis, and then a translation 4 units left

a reflection across x-axis, and then a translation 4 units right

a reflection across y-axis, and then a translation 4 units right

a reflection across y-axis, and then a translation 4 units left

Answers

B:  a reflection across the x-axis followed by a translation 4 units right.

Comparing the points to their mapped images compares A to E, B to F, C to G, and D to H.  In each point, the y-coordinate switches signs and the x-coordinate is subtracted by 4.

Reflections across the x-axis will switch the sign of the y-coordinate, and reflections across the y-axis will switch the sign of the x-coordinate.  Since the y-coordinates are the ones whose sign changed, the points must have been reflected across the x-axis.

Translations to the left will cause the x-coordinate to increase, and translations to the right will case the x-coordinate to decrease.  Since the x-coordinate of every point was subtracted, this means that the translation must have been to the right.

The correct series of transformations is a reflection across the x-axis, and then a translation 4 units left.

Let's start by labeling the vertices of quadrilateral ABCD as follows:

A(2, 4)

B(4, 5)

C(5, 4)

D(4, 1)

If we reflect quadrilateral ABCD across the x-axis, the new coordinates of the vertices will be:

A'(2, -4)

B'(4, -5)

C'(5, -4)

D'(4, -1)

Now, if we translate quadrilateral A'B'C'D' 4 units left, the new coordinates of the vertices will be:

E(-2, -4)

F(0, -5)

G(1, -4)

H(0, -1)

These are the coordinates of the vertices of quadrilateral EFGH.

Therefore, it can prove that for the transformation to quadrilaterals ABCD≅EFGH by reflecting quadrilateral ABCD across the x-axis and then translating it 4 units left.

The smallest value it could be is 4 and the largest value it could be is 10.

The triangle inequality theorem states that any two sides of a triangle must have a sum greater than the third side.  Given the two sides we have, 7 and 4, the sum would be 11; this would mean that the missing side could be no more than 10.

If we take the unknown side and the smallest one we're given, we would have the inequality
