Olivia picked 256 strawberries from the orchards fields. she divided the strawberries evenly into 6 baskets. how many strawberries are in each basket? how many are left over?
Answer:
42 strawberries are in each basket. 4 strawberries are left over.
Step-by-step explanation:
To find out how many she put into each basket, you need to divide 256/6. Your answer should 42.6666667. Round down to 42.
To find out how many are left over, multiply 42 x 6. You need to do this to figure out how many strawberries total she used trying to put them evenly into the baskets. Your answer should be 252. Then, you subtract 256 - 252. You do this to find out how many are left over. Your answer is 4.
The ratio of sugar to flour in the recipe is 1 to
2. If you use 5 cups of sugar, how much flour do
you need to use?
Answer:
10 flour
Step-by-step explanation:
1:2
5:x all you have to do is multiply by 2, sense the ratio is 1:2, flour will always be 2 times greater than sugar. so the answer is 5 x 2 =10
Solve for x in the equation 3x^2-18x+5=47
Answer:
x=3±√23thats the answer ^^
Step-by-step explanation:
plz give me brainlyest i need it
Answer:
Option 1
Step-by-step explanation:
[tex]3 {x}^{2} - 18x + 5 = 47[/tex]
[tex] = > 3 {x}^{2} - 18x + 5 - 47 = 0[/tex]
[tex] = > 3 {x}^{2} - 18x - 42 = 0[/tex]
[tex] = > 3( {x}^{2} - 6x - 14) = 0[/tex]
[tex] = > {x}^{2} - 6x - 14 = 0[/tex]
We know that
[tex]x = \frac{ - b + \sqrt{d} }{2a} \: or \: \frac{ - b - \sqrt{d} }{2a} [/tex]
Where D = Discriminant of the eqn.
Discriminant of the above eqn.=
[tex] {b}^{2} - 4ac = {( - 6)}^{2} - 4 \times ( - 14) \times 1 = 92[/tex]
So,
[tex]x = \frac{ - ( - 6) + \sqrt{92} }{2 \times 1} \: or \: \frac{ - ( - 6) - \sqrt{92} }{2 \times 1} [/tex]
[tex] = > x = \frac{6 + 2 \sqrt{23} }{2} \: or \: \frac{6 - 2 \sqrt{23} }{2} [/tex]
[tex] = > x = (3 + \sqrt{23} ) \: or \: (3 - \sqrt{23} )[/tex]
Triangle JKL is isosceles. The measure of angle J is 72 degrees and the measure
of angle K is 36 degrees.
Step-by-step explanation:
"which is the measure of angle L?"
the total angle measures of all angles on a triangle should always equal 180
72 + 36 = 108
180 - 108 = 72!
angle L is 72 degrees!
"which angle is the vertex angle?"
from my understanding, the angle opposite the base would be the vertex angle
since j and k are equal, we can only assume 36 is the vertex angle!
hope this helps! if so, pls give brainliest!

‐(5k – 3) ≤ 15 + 3k :) pls help
Answer:
k≥-1.5
Step-by-step explanation:
-(5k-3) ≤ 15 + 3k
-5k+3 ≤15 +3k
+5k +5k
3≤15+8k
-15 -15
-12 ≤ 8k
divide both sides by 8
-1.5 ≤ k
or k≥-1.5
Hope this Helps!!!
Answer:
Fraction Form:
[tex]k=-\frac{3}{2}[/tex]
Decimal Form:
[tex]k=-1.5[/tex]
Mixed Number Form:
[tex]k=-1\frac{1}{2}[/tex]
Step-by-step explanation:
The image below shows step-by-step on how to solve for k.

log3(2x-1)=3 help me out:(
Answer:
x = 2.
Step-by-step explanation:
(Brainliest?)
So log3(2x-1)+log3(x+7)=3 = log3(3^3) So (2x- 1)(x+7) = 27..... 2x^2+13x - 34 =0 (2x+17)(x - 2) = 0 ..so x = 2 or - 17/2. The solution x = - 17/2 is rejected since we cannot have log 3(2*- 17/2 - 1),a negative number. So the answer is x = 2.

What is the percentage decrease of y=320(0.665)^x
Answer:
33.5%
Step-by-step explanation:
The general form of an exponential equation showing decay is;
A = I(1-r)^t
The percentage part is 1-r
Equate this to what we have in the question
1-r = 0.665
r = 1-0.665
r = 0.335
This in percentage is 33.5%
Callum and Isabel have a total of 240 stamps.
The ratio of the number of Callum's stamps to the number of Isabels's stamps is 3:8
Callum buys some stamps from Isabel.
Please help I will award brainliest. :)
The ratio of the number of Callum's stamps to the number of Isabel's stamps is now 3:2
How many stamps does Callum buy from Isabel?
You must show all your working.
Original ratio: 3 + 8 = 11
240/11 = 21.818
3 x 21.818 = 65.5
11 x 21.818 = 174.5
New ratio: 3 + 2 = 5
240/5 = 48
3 x 48 = 144
2 x 48 = 96
Number of stamps bought = new amount - original amount:
144-65.5 = 78.5
Round to nearest whole number = 79 stamps bought

If the price is reduced by 30%, it is now 70% of the original price:
$70 × 0.70 = $51.10
The sale price of the headphones is $51.10.
how is the standard form, intercept form, and vertex useful when writing a parabola. (how is each form useful )
Answer:
The intercept form gives the x-intercepts, y-intercepts, and concavity of the parabola. Vertex form is most useful when graphing, since finding the vertex is much easier. Finally, standard form helps you find concavity and each a, b, and c terms tell different things about the postition of the parabola. Generally, this form is factored into one of the other forms. Hope this helped!
