Answer:
Weight in Kilograms = 0.8 Kilograms
Weight in grams = 800 grams
Step-by-step explanation:
Tyler has a baseball bat that weighs 28 ounces.
a) Weight in Kilograms
From the question:
1 kilogram = 35 ounces
Hence:
35 ounces = 1 kilogram
28 ounces = x kilogram
Cross Multiply
35 × x = 28 × 1
x = 28/35
x = 0.8 kilograms
b) Weight in grams
1 kilogram = 1000 grams
0.8 kilogram = x
Cross Multiply
x = 0.8 × 1000 grams
x = 800 grams
Is (2,6) a solution to this system of equations?
y = -1/2x + 7
y = 8x - 10
yes
no
Answer:
yes
Step-by-step explanation:
y = -1/2x + 7
6 = -1/2(2) + 7
6 = -1 + 7
6 = 6
y = 8x - 10
6 = 8(2) -10
6 = 16 - 10
6 = 6
Triangle DEF is dilated to create triangle DAB. What scale factor was used?
please hurry in less than 10 min
Answer:
Not sure how you would word it but the bigger triangle is 2 times larger than DEF.
Step-by-step explanation:
DE=4
AE=4
4+4=8
AD=8
Hope this helps!!
The scale factor used to create DAB from triangle DEF is 2.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
The length of the base of the triangle DEF is 4 units and of DAB is 8 units.
The length of the height of DEF is 3 units and that of DAB is 6 units.
From this, we conclude that the scale factor is 2 as 8 is a multiple of 2×4 and 6 is a multiple of 2×3.

Find the exact value of x using the pythagorean theorem.
Do the side lengths for a pythagorean triple?
Answer:
Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle. However, right triangles with non-integer sides do not form Pythagorean triples.

Answer:
19/15
Step-by-step explanation:
To solve this, we need to add 2/3 and 3/5, to do this, we need to find the LCM of 3 and 5, that is 15. We multiply 2/3 by 5/5 and 3/5 by 3/3. This gets us 10/15 + 9/15. When we add those together, we get 19/15.

In a survey of 3,500 people who owned a certain type of car,1,925 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: percent of the people surveyed that were satisfied with the car= 55%
Step-by-step explanation:
Step 1
Total Number of people in the survey who owned certain type of car = 3,500
Number of people that would buy that type of car again = people surveyed that were satisfied with the car= 1,925
Step 2
Percentage of people satisfied with the car= people surveyed that were satisfied with the car/Total Number of people in the survey who owned certain type of car x 100
=1925 / 3500 x 100
=0.55 x 100
=55%

Answer:
im guessing D sorry if wrong
Answer: D
Step-by-step explanation:
Since the scale factor is 4:1, you need to divide each side by 4.
10 / 4 = 2.5
12 / 4 = 3
Also you can clearly rule out answer choices b and c because they just don’t make since since the object is smaller than the scale drawing.

The seventh grade class is raising money to have a class trip at the end of the year. They began the year with $1500. They now have $1650 in the account. What is the percent of increase for the money the class has raised ?
Answer:
The percent of the increase for the money the class raised is 10 %
Step-by-step explanation:
Because if you divide 1500 by 10 you get 150 that means 150 is 10 % of 1500 and if you add 150 to 1500 you get 1650 so the increase of money the class raised is 10 %

An account with an initial deposit of 3,500 earns 7.25% annual interest, compounded continuously. How much will the account be worth after 30 years? Round to the nearest cent.
Answer: $28,575.05
Step-by-step explanation:
Formula: FV = (1+r/n)^nt
FV = future value of the deposit
P = principal or amount of money deposited
r = annual interest rate (in decimal form)
n = number of times compounded per year
t = time in years.
3,500(1+7.25%)^30=28,575.05468
Jamar wants to rent a car for a trip. He calls the rental company to get prices. Cars rental charges $99 for one week plus $0.11 per mile what is the slope
Can anyone help me answer this?
Answer:
Vertex is (-1,1)
Y-intercept is (0,0)
Axis of symmetry is x= -1
i need to identify the slope and the y-intercept of the line with a given equation, the given equation is y = 1/2x +5 . i need to graph it aswell.
Answer:
y-intercept: 5
slope: 1/2
Step-by-step explanation:
The equation y=1/2x+5 is an example of y-intercept form(y=mx+b). This is where b represents the y-intercept and m represents the slope. I will not graph this for you but can explain it.
First plot the y-intercept on the graph. (0.5). Then use the slope to find the next point off of the y-intercept. So for example, the next point would be (2,6).
Annie spent 2.5 hours doing homework. She spent 1/3 of the time on her history project. She spent 3/5 of the remaining time solving math problems. After that, Annie spent all remaining time writing an essay. How much time did Annie spend writing the essay?
Step-by-step explanation:
2.5 hours = 150 min
1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover
3/5 of 100 min is 60 min (1 hour) = 40 min leftover
She spent 40 min writing her essay
