Answer:
4.1 kilograms
Step-by-step explanation:
A farmer sells 7.6 kilograms of apples and pears at the farmer's market. 3.5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
= 7.6 kilograms - 3.5 kilograms
= 4.1 kilograms

Janine and her older sister Ingrid's ages are consecutive even numbers. When Janine's age is divided by seven, and Ingrid's age is divided by three, the sum of those numbers is fourteen. How
old are Janine and Ingrid?
Answer:
Janine is 28. Ingrid is 30.
Step-by-step explanation:
Let the ages be x and x + 2 for Janine and her sister, respectively.
x/7 + (x + 2)/3 = 14
Multiply both sides by the LCD, 21, to get rid of denominators.
21 * x/7 + 21 * (x + 2)/2 = 21 * 14
3x + 7(x + 2) = 294
3x + 7x + 14 = 294
10x = 280
x = 28
x + 2 = 30
Answer: Janine is 28. Ingrid is 30.
Answer:
Janine is 28 and Ingrid is 30.
Step-by-step explanation:
Let Janine's age be x years , then Ingrid's age is x+2 years.
From the given information we have the equation:
x/7 + (x + 2)/3 = 14
Multiplying through by the LCM of 3 and 7 (21), we have:
3x + 7(x + 2) = 294
10x + 14 = 294
10x = 294-14 = 280
x = 28, so:
Janine is 28 and Ingrid is 30.
Which graph represents the function f(x) = 3/2(2)x
The fourth graph represents the function [tex]f(x)=\frac{3}{2} 2^{x}[/tex]
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is [tex]y=\frac{3}{2} 2^{x}[/tex]
It is an exponential function and 2>1, therefore it is an increasing in nature.
put x=0 in the given function to find the y-intercept of the graph.
f(0)=3/2.2⁰
f(0)=3/2(1)
f(0)=3/2=1.5
So, the y-intercept is 1.5.
In figure 1 and figure 1 the y-intercept is 1, in figure 2 the y-intercept is 2 , therefore first three options are incorrect.
In figure 4 the y-intercept is 1.5, therefore the option 4 is correct.
Hence, the fourth graph represents the function [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

A baseball is hit in the air. Its height above the ground is described by the function
Ht=-16t^2+45t+5, where H(t) represents the height in feet of the ball t seconds after it is hit. To the nearest hundredth of a second, for how much time will the ball be in the air? Find algebraically.
help guys plz i suck at math, also step by step is needed Branliest is the reward like always
Answer:
2.9195
Step-by-step explanation:
To find the time we need to equate the function the zero and solve for t:
[tex] { - 16t}^{2} + 45t + 5 = 0[/tex]
Using the general formula we have that:
[tex]t = \frac{ - 45 + \sqrt{ {45}^{2} - 4 ( - 16)(5)} }{2( - 16)} \\ = \frac{ - 45 + \sqrt{2345} }{ - 32} [/tex]
then:
[tex]t = \frac{ - 45 + \sqrt{2345 } }{ - 32} = - 0.107 \\ or \\ t = \frac{ - 45 - \sqrt{2345} }{ - 32} = 2.9195[/tex]
Since the time has to be positive we conclude that the ball is in the air 2.9195 seconds.
Lanna's dad was teaching her about the stock market. He has 100 shares of Company A stock
valued at $45 a share and 250 shares of Company B stock valued at $22 a share. How much is
his stock worth?
Answer: $10,000
Step-by-step explanation:
Lanna's dad stock worth will be the value of the total shares in both company A and company B.
Value of stock in company A = 100 × $45 = $4500
Value of stock in company B = 250 × $22 = $5500
Total stock worth = $4500 + $5500 = $10,000

Answer:
19
Step-by-step explanation:
Rearranging the number in ascending order,
12,15,17,19,19,20,24,26
Median = The average of the 4th and 5th number
[tex] = \frac{19 + 19}{2} \\ = 19[/tex]
Answer:
19
Step-by-step explanation:
so first you have to order the values from least to greatest.
12, 15, 17, 19, 19, 20, 24, 26
there are 8 terms (note that 2 of them are 19)
n = 8
median = (n + 1) ÷ 2
=(8 + 1)/2
=9/2 = 4.5
it's 19 because the median falls between those two (19) data points.

Find the value of the lettered angles in these diagram
Answer:
1. m = 65°
x = 30°
2. x = 40°
Step-by-step explanation:
1. Since the figure is an isosceles triangle, m = 2x - 5
180 - 50 = 130 (Total degree for both m and 2x - 5)
130 ÷ 2 = 65 (m and 2x - 5 angle degrees)
65 - 5 = 60 (2x)
2 x = 60°
x = 60 ÷ 2 = 30°
2. I forgot the parallel rule for question 2, but I think X and 40° is parallel to each other?

a school has 36 fish swamps 4/6 of them's are boys how much are girls
Answer:
12 fish are girls
Step-by-step explanation:
multiply 4/6 by 6 which would be 24/36. Then substract 24 from 36 and you get 12.
Answer:
12 are girls
Step-by-step explanation:
Reason that since 4/6 of them are boys then that means 2/6 are girls
then convert 2/6 to decimal form which is 0.3333....
then multiply that by 36 which gives us 12
you could also go the roundabout way and convert 4/6 to decimal form and take that value and multiply it by 36 which gives us 24 then subtract 24 from 36 which still gives us 12

Let AB be the directed line segment beginning at point A(5 , 5) and ending at point B(19 , 16). Find the point P on the line segment that partitions the line segment into the segments AP and PB at a ratio of 5:2.
Answer:
(9, 57/7)
Step-by-step explanation:
Given the coordinates A(5 , 5) and B(19 , 16), divided by the point P in the ratio 5:2, to get the coordinate of P, we will use the formula;
P(X, Y) = {{ax1+bx2/a+b, ay1+by2/a+b}
X = ax1+bx2/a+b
Substitute the given values
X = 5(5)+2(19)/5+2
X = 25+38/7
X = 63/7
X = 9
Similarly;
Y = 5(5)+2(16)/5+2
Y = 25+32/7
Y = 57/7
Hence the coordinate of point P is (9, 57/7)
