The equation would be y = 25x + 50
In order to find this equation, we need to know how much the gift from her grandparents was. To do so, we have to find out how much she's saved from dog walking.
Since she saves $25 a month for 7 months, we can find the total amount as:
25*7 = 175
Then we can subtract that from the total she has saved to find the amount for the gift.
225 - 175 = 50
Finally, we put the amount per month in the equation with the gift as the y intercept to create the equation above.
Answer:
9 books on each shelf
Step-by-step explanation:
43 + 29 = 72 books total
72/8 = 9 books per shelf
Answer: number= 5.5; equation: 4x+8=30
Step-by-step explanation:
Take x for the unknown number. Then just follow the words and turn them into mathematical symbols. Easy.
Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.
Step-by-step explanation:
For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.
in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.
Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.
Two triangles in sphere that are similar must be congruent.
So supplementary is an 180 angle and complimentary is 90 degree angle so that being said I could be wrong but that looks like a complimentary so a 90 degree angle it’s a 90 degree
