The ratio of red marbles to black marbles is 4:7. If the bag consists of 77 marbles in all, how many red marbles are in the bag?
Step-by-step explanation:
The ratio of red marbles to black marbles = 4 : 7
Total no. of marbles = 77
4x + 7x = 77
11x = 77
x = 77/11
x = 7
The no. of red marbles = 4x
= 4 × 7
= 28
what is the area of the figure to the nearest hundredth renter the answer in the box 2yd 4yd
Answer:
9.57 yd squared
Step-by-step explanation:
we can divide this figure into two shapes: a rectangle and a semi-circle
since we know the length and width of the rectangle, all we ahve to do is multiply them together to find the area: 8 yd squared
for the semi-circle, we know the area is [tex]\frac{\\\pi r^2}{2\\}[/tex]
raduis is half the diameter so 1 yd
[tex]\frac{3.14(1)^2}{2}[/tex]
[tex]\frac{3.14}{2}[/tex]
1.57 yd squared
lastly, add the area of the two figures together 8+1.57

Find the product
(4x-5)(4x-1)
Answer:
80
Step-by-step explanation:
(4x-5)(4x-1) = 80
Answer:
16x² - 24x + 5
Step-by-step explanation:
Given
(4x - 5)(4x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(4x - 1) - 5(4x - 1) ← distribute both parenthesis
= 16x² - 4x - 20x + 5 ← collect like terms
= 16x² - 24x + 5

On a coordinate plane, a curved line labeled f of x with a minimum value of (1.9, negative 5.7) and a maximum value of (0, 2), crosses the x-axis at (negative 0.7, 0), (0.76, 0), and (2.5, 0), and crosses the y-axis at (0, 2).
Which statement is true about the graphed function?
F(x) 0 over the intervals (-∞, -0.7) and (0.76, 2.5).
F(x) 0 over the intervals (-0.7, 0.76) and (0.76, ∞).
Answer:
The answer is D
Step-by-step explanation:
EDGE2020
The answer is:
A) F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)
F(x) is the output, or y values, and the y values on this coordinate plane from (negative infinity, -0.7) to (0.76, 2.5) do not have values above 0. Hence, F(x) is less than 0 over the given intervals.

Answer:
y = 2x - 2
Step-by-step explanation:
Slope-intercept form is y = mx + b
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
(1, 0)
(2, 2)
(3, 4)
(4, 6)
m = [tex]\frac{2-0}{2-1}[/tex] = 2
y = 2( x - 1 )
y = 2x - 2
x + 10y = 30
to
y = mx + b form
Answer:
y = - [tex]\frac{1}{10}[/tex] x + 3
Step-by-step explanation:
Given
x + 10y = 30 ( subtract x from both sides )
10y = - x + 30 ( divide all terms by 10 )
y = - [tex]\frac{1}{10}[/tex] x + 3

An alloy is a mixture of metals.Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.
Answer the questions below. Do not do any rounding.
(a) How many grams of copper are in the resulting mixture?
Il grams
(b) What percentage of the resulting mixture is copper?
Answer:
(a) How many grams of copper are in the resulting mixture?
= 160 grams
(b) What percentage of the resulting mixture is copper?
= 61.5%
Step-by-step explanation:
(a) How many grams of copper are in the resulting mixture?
From the question: Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.
The number of grams of copper in the resulting mixture = 70 grams + 90 grams = 160 grams
(b) What percentage of the resulting mixture is copper?
70 grams of an alloy that contains 12% copper = 70 × 12%
= 70 grams × 0.12
= 8.4 grams
The number of grams of copper in the resulting mixture = 160 grams
The percentage of the resulting mixture that is copper is
=( 8.4 grams + 90 grams of pure copper/160) × 100
= 98.4/160 × 100
= 61.5%

What is the solution of the proportion 3/5=13/x ? Round to the nearest tenth if necessary.
Answer: x = 21 2/3
Step-by-step explanation:
3/5 = 13/x
cross multiply 5 × 13, then divide by 3.
65/3 = 21 2/3
It's like multiplying both sides by the reciprocal of the left side.
