5)x= 67° and y= 32°

(x-15)°=52°(vertically opposite angles)

=>x= 52+15° = 67°

Similarly, 4y= 128°(vertically opposite angles)

=>y=128/4= 32°

6) x= 5° , y= 22°

12x+15=75°(vertically opposite angles)

12x=75-15°

12x=60°

x= 5°

Answer:

The surface area is 294 ft^2 (please give branliest)

Step-by-step explanation:

area of one side 49

multiply by 6 sides

The surface area of the cube is equal to 294 square inches.

How to calculate the surface area of the cube

In this problem we find the representation of a cube, whose surface area, that is, the sum of the areas of all faces of the cube, must be computed in accordance with this formula:

A = 6 · l²

Where:

If we know that l = 7 in, then the surface area of the cube is equal to:

A = 6 · (7 in)²

A = 6 · 49 in²

A = 294 in²

The cube has a surface area of 294 square inches.

Answer: x=8

Width=8 inches

Length=13 inches

Final answer:

The width of the rectangle is 8 inches and the length is 13 inches, as determined by solving the quadratic equation representing the area of the rectangle.

Explanation:

To solve for the dimensions of the rectangle, we need to find the value of x, which represents the width of the rectangle. The quadratic equation we have is x² + 5x - 104 = 0.

Factoring this equation, we are looking for two numbers that multiply to -104 and add to 5.

These numbers are 13 and -8, so the equation factors to (x + 13)(x - 8) = 0. Setting each factor equal to zero gives us two possible solutions for x: x = -13 or x = 8.

Since a width cannot be negative, the only sensible solution for this problem is x = 8 inches. Given that the length is 5 inches more than the width, the length will be 8 inches + 5 inches = 13 inches.

Dimensions of the rectangle:

Width = 8 inches

Length = 13 inches

Answer:

31

Step-by-step explanation:

The function given in this problem is described by the expression

[tex]f(x)=3x+1[/tex]

In this problem, we want to find

[tex]f(10)[/tex]

Which means that we want to evaluate the function when the value of x is 10, so when

[tex]x=10[/tex]

To solve the problem, we just need to substitute x = 10 into the expression of f(x). By doing so, we find:

[tex]f(10)=3\cdot 10 +1 = 30+1 = 31[/tex]

Therefore, the correct option is

175 went to screen 3

Step-by-step explanation:

10% is 50 so 50 x 4 =200

25% of 500 is 12, divide 500 by 4

35% is 25% + 10% = 125 + 50 = 175

Answer: AB=5.66, AC=4

Step-by-step explanation:

So this triangle is a 45-45-90 triangle, meaning it has one 90 degree angle and two 45 degree angles.

If you remember from geometry, the sides that have the same angle have the same length, and seeing as angle A is 45 degrees and side BC is 4, we can know for certain that angle B is 45 degrees and side AC is also 4.

This is because angle C is already marked as the 90 degree angle due to the square symbol in it.

Now to find side AB, we would use our friend the Pythagorean Theorem, which states that [tex]a^2+b^2=c^2[/tex].

Let a = side BC and b = side AC, meaning c = side AB.

Now plug in the values and solve:

[tex]4^2+4^2=c^2[/tex]

[tex]32=c^2[/tex]

[tex]\sqrt{32} =\sqrt{c^2}[/tex]

[tex]5.65685=c[/tex]

Answer:

He earned $9.25

Step-by-step explanation:

First, you have to create an equation.

346.88= 37.5h

Then divide 346.88 by 37.5

You get 9.25=h

Rodrick earned $9.25 per hour.

Rodrick earned approximately $9.25 per hour.

To find out how much Rodrick earns per hour, we need to divide his total pay by the number of hours worked. In this case, Rodrick worked for 37.5 hours and earned $346.88. So, to find his earnings per hour, we divide $346.88 by 37.5:

Earnings per hour = Total pay / Number of hours

Earnings per hour = $346.88 / 37.5

Earnings per hour ≈ $9.25

Therefore, Rodrick earned approximately $9.25 per hour.

Answer:

The correct option is;

(x, y) → (215·x, 215·y)

Step-by-step explanation:

An enlargement is a form of transformation involving an alteration of the size of the shape. When a shape is to be enlarged, the center of the shape is noted and the enlargement of the dimensions of the shape from that center is by multiplication of each point by the factor of the enlargement or the scale factor.

Therefore, based on the requirement for enlargement, and given the dimension of the point from the center as (x, y) the enlargement then is (215·x, 215·y), where 215 is the scale factor.

Answer:

A. (x, y) → (215x, 215y)

Step-by-step explanation:

Enlargement of a figure is the process of increasing the size of a given figure by the use of a scale. It requires the use of a scale factor that is greater than 1 to form an image. This is called dilation in transformation.

Transformation is the process of manipulating the size or orientation of a figure. To enlarge a shape, a center of enlargement is required.

Thus, the rule that signifies enlargement of a figure is ;

(x, y) → (215x, 215y)

This implies multiplying the initial coordinate x and y by a factor of 215 to produce a required size of an image.

Final answer:

Cruz's running speed is 10 mph, and his biking speed is 16 mph, which we found by setting up an equation representing the total distance he covered and the time spent on each activity at their respective speeds.

Explanation:

To determine Cruz's biking and running speeds, we can use the information given about the total distance and the ratio of his speeds. The information tells us that Cruz ran for 1.5 hours (from 6:00 to 7:30) and biked for 2.25 hours (from 7:30 to 9:45). If we let r represent his running speed, then his biking speed would be 1.6r because it's said to be 1.6 times his running speed.

Cruz's total running distance would then be r × 1.5 hours, and his biking distance would be 1.6r × 2.25 hours. We know that the total distance covered is 51 miles, so we can set up the following equation:

1.5r + 1.6r × 2.25 = 51

Now, solve for r:

1.5r + 3.6r = 51

5.1r = 51

r = 51 / 5.1

r = 10 miles per hour

Therefore, Cruz's running speed is 10 mph, and his biking speed is:

1.6 × 10 mph = 16 mph

Cruz's running speed is 10 mph, and his biking speed is 16 mph.

Answer:

The student answer is wrong. The correct length of the hypotenuse is 12

Step-by-step explanation:

The question is incomplete without diagram. Find the diagram attached below.

The longest side of the right angled triangle is the hypotenuse.

The side facing the angle 30° is the opposite side of the triangle.

To find the hypotenuse, we will use the SOH CAH TOA method in trigonometry identity.

According to SOH:

Sin30° = Opposite/Hypoenuse

Sin30° = 6/Hypotenuse

Hypotenuse = 6/sin30°

Hypotenuse = 6/0.5

Hypotenuse = 6×2

Hypotenuse = 12

The student answer is wrong. The correct length of the hypotenuse is 12

Answer:

(-16,24)

Step-by-step explanation:

In this problem, we have segment PR, where the endpoins have coordinates

P (-22, 32)

R (5, -4)

We want to find point Q along the segment such that

PQ : QR = 2 : 7 (1)

We can write the coordinates of point Q as

[tex]Q(x_P,y_P)[/tex]

So we can now rewrite eq(1) for both the x- and y- variable:

[tex]\frac{x_Q-x_P}{x_R-x_Q}=\frac{2}{7}[/tex] (2)

[tex]\frac{y_Q-y_P}{y_R-y_Q}=\frac{2}{7}[/tex] (3)

We start by solving eq(2) to find the coordinate x of point Q:

[tex]7(x_Q-x_P) = 2(x_R-x_Q)\\7x_Q-7x_P=2x_R-2x_Q\\9x_Q=2x_R+7x_P\\x_Q=\frac{2x_R+7x_P}{9}=\frac{2(5)+7(-22)}{9}=-16[/tex]

While for the y-coordinate:

[tex]7(y_Q-y_P) = 2(y_R-y_Q)\\7y_Q-7y_P=2y_R-2y_Q\\9y_Q=2y_R+7y_P\\y_Q=\frac{2y_R+7y_P}{9}=\frac{2(-4)+7(32)}{9}=24[/tex]

So the coordinates of Q are (-16,24).

The coordinate of Q is [tex]Q=(-16,4)[/tex]

To understand more, check below explanation.

To find the coordinate of Q, we use section formula,

                             [tex]Q=(\frac{m_{1}x_{2}+m_{2}x_{1}}{m_{1}+m_{2}},\frac{m_{1}y_{2}+m_{2}y_{1}}{m_{1}+m_{2}} )[/tex]

It is given that,

           [tex](x_{1},y_{1})=(-22,32),(x_{2},y_{2})=(5,-4), m_{1}=2,m_{2}=7[/tex]

Substitute above values in above section formula,

             [tex]Q=(\frac{(2*5)+(7*-22)}{2+7}, \frac{(2*32)+(7*-4)}{2+7})\\\\Q=(-\frac{144}{9} ,\frac{36}{9} )\\\\Q=(-16,4)[/tex]

Therefore, the coordinate of Q is [tex]Q=(-16,4)[/tex]
